Normally headers are large-diameter pipes with several connecting branches. Each branch will have its own isolation valves. They may require access platforms. 9. Platform piping is the major part of a model. As per each contract requirement, all pipes above a certain size will be included in ...

If the Getter Flash turns from silver to ash white you know the tube has been contaminated with too much oxygen from a vacuum leak. Dual Triode Tube The glowing hot tubes are the dual cathodes (this is a dual triode design). The horizontal lines across the cathode are the control grid ...
All implanted medical devices, from transient, easily inserted, and retrieved contact lenses, urinary catheters, and endotracheal tubes, to more permanently surgically implanted cardiac valves, embolic coils, vascular grafts, hip, knee and shoulder joints, pacemakers, coronary stents, and plastic surgery...
Nope. Integrated Circuits? Definitely not. What does that leave us with? Vacuum tubes (Valves for those across the pond), resistors, capacitors, relays, and… motors? Yep. Motors. The unit is artfully constructed, and we mean that quite literally- the build was clearly done with care and...

Groove Tubes are a company best known to guitar players for their matched sets of valves, but they also produce valve amplifiers, outboard processors and microphones. Their MD1, 2 and 3 mics have enjoyed success for a number of years, but now they've been given new amplifier circuitry to ...
Of course, tubes were generally phased out in favor of transistors largely due to their power and space requirements; [Mike] needs a stepladder to maintain this computer as well as around ten minutes each time he starts it up to allow the tubes to warm up, with each module needing over ...
including dual triodes. The glass envelope of an octal tube was cemented into a Bakelite or plastic base with a hollow post in the center, surrounded by eight metal pins. The wire leads from the tube were soldered into the pins and the pinched-off nub through which the air was evacuated...
associated pipes, valves, and instrumentation. In a manner analogous to that of a condenser, external reboiler heat exchangers may also provide vapor to (rather than remove vapor from) the column by heating a liquid stream removed from the bottom section of the column. Likewise, vapor and ...
