Seen here – the sight glass and automatic air vent at the high point of the system.
Until today I never gave too much thought to this cooling system, and it seems I should have done so more often as it was sitting there at zero pressure. Yikes. In fact… its pressure had gone so low that the janky little pressure gauges were doing this.
I have no idea how it managed to slip around to the wrong side of the pin, but it’s a really garbage tier gauge so I guess that’s no surprise.
Refilling the system is a matter of just opening the vent caps on the air vent valves, admitting fresh coolant to the system via that tap on the pump suction side, and creating backpressure in the system by closing the suction side valve partially. This causes backpressure to build up in the system and compress the air bladder inside that tank while making the pump draw more coolant in from the source. Once it’s run for a while you can close the vent caps on the valves so they don’t, uh—
yeah I wonder if this is why and where the pressure all got out — all the vent caps were open, and, ew
The instruction manual on this GatesAir system states that you don’t really need to worry about overfilling it because that spring loaded relief valve will lift and burp out the excess if it gets over the maximum of 75 PSI.
Both of the two transmitter cabinets in this installation have their own cooling system, and there’s a third for the glycol solution cooled RF loads. That one’s holding its pressure just fine.
Now for… uh… cursed things
Speaking of toilets— it was time to give amplifier #3 on the Space Station Toilet a new Barnstead filter. As I experienced previously, touching anything on the Barnstead led to leaking as the shrunken hardened gaskets started crumbling. I think I’d kinda vaguely alluded in a previous post to this filter holder unit having hilariously cursed input and output connectors, but I hadn’t gotten good pictures of the thing. I had, however, looked all over Thermo Fisher’s catalogs and webpage trying to find the proper gaskets for this thing and could never find the same series of connectors. Their current models of the Barnstead filter holders do not use this same stuff. This raises the question of which of the two is true:
1) Thermo Fisher switched suppliers for their filter holder assemblies at some point in time, the new manufacturer uses a different system, and they do not have parts in stock for the old system.
2) Thermo Fisher has realized this old system is complete garbage and does not even want to admit to having ever made it.
I’m leaning towards 2. Without further ado, here’s… this thing. The fitting can swivel a bit, but doing so tends to lift the two pins out. You can see their heads here.
Removing the pins releases the connection completely.
Looking down the bore at the weird gasket:
And finally, the connector itself, with BIG RAUNCHY MOLD MARKS THAT JUST MAKE LIFE DIFFICULT:
YUCKY STUFF AHEAD
So my coworkers had told me in the past about some kind of “carbon” that tended to circulate in the system on this transmitter, likely contributing to how it lays waste to the cooling water flow sensors. I was a little baffled, where would this come from? This system is just supposed to be full of PURE deionized water to maintain proper electrical resistivity and not clog things up. Well then, uh—
Imagine my amazement and horror when I dropped the Barnstead filter housing down and just saw it fill up with this inky yackage.
I poured it into a clear plastic water bottle for inspection. It looks like diluted India ink, and thankfully, smells like nothing. Coarse particles settled to the bottom, but even after sitting a couple hours, not everything settles out. I’m wondering if this is the result of the Barnstead filter just releasing small activated charcoal particles when the water flow stopped and reversed a moment, or if that’s really just… floating around in there. If so, where is all that coming from? Ew ew ew ewwwwwwwwwwwww
Let’s just say the only way out of this one is an emergency capital expenditure request that’s being made as I speak. The servo balanced LTC output is somehow half burned up on the working one of the two and this can’t be fixed without taking the unit out which means NOOOOOO TIMECODE *whistle boing*
That remains unfixed but I’m really happy for an unrelated and wonderful reason.
Yeah that’s apparently not a thing at all here. I’m so glad. I think at worst maybe one of my coworkers was very slightly confused because he was used to referring to me by male pronouns and I guess kinda questioned that for a moment but that really doesn’t bother me at all. I have thought maybe I should introduce myself using they/them to avoid confusion but… whatever works.
Oh and yes this was me being rather lazy, really I just wanted to wear my favorite dress at work somehow and then realized I had a set of cat ears that matched it! It worked out so well and everyone was trying to figure out what anime I was from. Well….. I’ve often thought a somewhat ridiculous anime about broadcast engineering should exist— think maybe what you’d get if you crossed Azumanga Daioh with a TV and radio station. Meow.
I wish to point out something ridiculous here. In the photo I took in the dark, a lot of that light reflecting off my dress is a whole stack of windows open on my desktop PC as I give our ChyronHego graphics systems their weekly, uh, wash, rinse, and tri-color foaming wax or whatever. These things are high maintenance and just as I was about to leave for the afternoon to go take a cat nap, the Camio Luci component of…. whatever….. Blew The F Up.
Guess what turned out to secretly actually just be Software As A [dis]Service with a weird local hardware-ish interface to the on site newsroom automation all along?
*Scooby Doo villain unmask scene!*
Yeah apparently ChyronHego support told us yes they’re down and we can’t generate any supers or lower thirds because…. Blurrrrrppp. Excuse me, I think I need to go sharpen my claws on the cat tree.
It’ll still start and stop recording video on time. It’ll still play out video. It still archives video properly.
But that’s where it ends because once it’s taken a nice hit (in this case due to bad LTC timecode that was passing through a distribution amp that shat out its power supply capacitors) it will just
It will just
No timecode. No more timecode. Ever.
And this completely thunderfucks your editing workflow.
Seriously. All I can get out of it after fixing the bad DA is the Summit 3G client machines assuring me in their logs the LTC timecode (which provides the time of day in hours, minutes, seconds, and frames- 29.97/sec because NTSC) is present and good and then it just
And then it Makes Shit Up as it goes along
So far I’ve received clips where the TC starts at 00:00:00.00 and never advances as recording progresses, regardless of the Free Run setting, and that’s a major Everlasting Cockstopper because it makes it impossible to set an in and out point to generate a subclip later…
I’ve gotten clips where the timecode starts rolling correctly BUT it’s 23 minutes and some odd sec/frames in the past which is really strange but you can still mark in and out…
And I’ve gotten clips where the time starts at 00:00:00.0 but counts up properly. Weird but also harmless
But until its desired behavior is fully back I’m getting nonstop phone calls about it and it’s all just a great pile of piss streaming forth from a god awful product that never, ever, fully worked as advertised and was constantly unstable for the first few months we had all our eggs inexorably in it’s basket.
Stratus, let it be known I hate your lifeless yet malevolently vile shitty software driven guts and you make me wish I could just put everything back on fucking U-matic tape.
73’s and go fuck yourself, you piece of techbro turd. Guess I’ll be trying to get an appointment with one of Ass Valley’s two support techs tomorrow.
I mean seriously, you’re telling me it’s possible to combine the output of two transmitters and NOT allow RF to directionally flow the wrong way out of the system like letting the output of one of the transmitters appear at the other? Of course you’d have to go and call one of the systems for this a Magic Tee Combiner.
And then you have this one that’s also filters made of giant metal tubs. What magic is going on? Seriously? I hope whoever gets to sit there with an analyzer and tune all those gribbles gets paid very well for this because they’ve deserved it for going this far down the rabbit hole. My brain would just blow a capacitor.
Ever had water start gushing out of something that’s fundamentally made of eldritch terror and high voltage? Why I’ve never…..
And it gave me a nice shower the moment I got the door open. And I accidentally did the Wrong Button Thing again in the confusion.
So the fitting that became a showerhead is the one on the left. I didn’t get a picture of it but basically it’s the same as half of that coupler I found in a parts box that’s sitting on top… However it didn’t have the O-ring. The snapped trapezoidal profile ring sitting on the right sits in the bottom of the socket. The fitting plugs in there, held against the trapezoidal ring by two locking pins, you can see the head of one of them on top here. I can’t identify the type of connector or even find any evidence that it ever existed. Anywhere. Needless to say I didn’t have a spare for that ring, but luckily taking one of the round o rings off that close nipple and putting it in the seat in the socket and reinstalling the thing worked! No more warm shower of DI water.
Oh, and now I know how the funky bascule bridges work. A rather buzzy motor cranks up in there and rotates pinion gears that engage with rack gears on these two long braces on each side of the bascule, which protrude outward from the waterway to lift the well balanced assembly. You would be well advised to stay clear of that counterweight as it comes awkwardly close to the road surface as it nears fully open!
And this is uhh, Stuffing Shit In Tower Elevators, Medium Difficulty Level. I rode down squatted inside the cabinet and it wasn’t the best. The elevator is kinda both bigger and smaller than it looks as it’s a weird shape and the control cabinets stick out. If there isn’t a large object rammed in the, there’s enough space to comfortably sit down on the floor as it slowly creeps its way up or down at 85 feet per minute.
