Filed: 1956-09-04
Abstract: 832,356. Valves. GAS COUNCIL. Dec. 3, 1957 [Sept. 4, 1956], No. 27040/56. Class 135. A chamber 11, which houses a diaphragm 12 of reinforced rubber or other flexible waterproof material, incorporates a pocket 13 in its bottom wall 10 that communicates with the inlet 2 by a tube 14 whilst the space above the diaphragm 12 is open to the outlet 3 through a port 15. The diaphragm 12 has an upper plate 16, spaced from the diaphragm by a washer 28, and a lower plate 17, the whole being carried by a spindle 19 that is ball-jointed to the closure member 22 provided with a gas-tight cap 29; the spindle passes through a tube 24 in the outlet 3. In the valve closed position shown, the plate 17 fits into but does not touch a recess 27 in the wall 10, the diaphragm around plate 17 seating on the wall 10 and forming a seal therewith whilst the inlet pressure only acts on the diaphragm 12 over the area of the recess 27, therefore the inlet pressure must be greater than that in the outlet before the valve will open. In the latter position, shown dotted, the inlet pressure acts over the whole diaphragm area but the valve is only maintained open so long as the upward force on the diaphragm is greater than the opposite force due to outlet pressure acting thereon in conjunction with the weight of the closure member 22 and other moving parts. Port 15 is of larger section than tube 14 whilst both are small compared to the inlet 2 and outlet 3 so that pressure fluctuations are damped before reaching the chamber 11. The valve can be made to close when the inlet pressure is greater or less than the outlet pressure by adjusting the weights of the moving parts and/or the effective area of the upper diaphragm face.

Title: Optical gauging system
Inventor: WESTBROOK MICHAEL HEREWARD
IPC: G01B11/24
Filed: 1960-08-05
Abstract: 963,842. Electric selective signalling systems. ASSOCIATED ENGINEERING Ltd. July 31, 1961 [Aug. 5, 1960], No. 27230/60. Heading G4H. The invention provides systems for gauging an engineering component, e.g. a piston wherein gauging at a number of heights can be performed at the same time. In a first embodiment, Fig. 1, a piston 6 to be gauged is placed before a short persistence cathode ray tube 1 which is displaying a raster with one beam, and with another is producing a single trace in synchronism with the horizontal sweep of the raster. A scale 4 is placed in front of the single trace, so that a photo-cell 11, viewing the light spot, produces timing pulses. The timing pulses pass to a gate 14 which is open only when photo-cell 10 is receiving light from the raster. A further gate 15 is opened under control of unit 23 when the scanning electron beam has reached a certain level on the raster so that the pulses relevant to that line are passed to a counter 24. The number of pulses counted will be the number corresponding to one line of raster scan less the pulses blocked by the presence of the piston. Unit 23 provides further pulses which correspond to the correct width of the piston at the height under consideration, and these pulses are also fed to counter 24. If the final count on unit 24 is above or below a certain value the piston is too narrow or too wide. Unit 23 is programmed so that a plurality of measurements is made during one raster scan. The counter outputs may operate a reject mechanism, or control the machine producing the pistons, and may be recorded by a printer. In a second embodiment, Fig. 3, the piston 36 is carried on a moving platform which is associated with a moirÚ fringe grating system. An optical unit 42 coacts with the grating system to produce pulses indicative of the movement of the platform. Each of these pulses is fed to gates 55 and also causes one vertical scan of the beam of a short persistence c.r.t. 31, and unit 47 produces brightup spots on the tube face, the spots being positioned on the scan according to the several heights at which gauging is to be performed. The spots are detected, unless obscured by the piston, by a photocell 40 whose output closes gates 55. Unit 47 supplies a pulse to each gate in turn concurrently with the corresponding bright-up pulse. Thus counters 56, each representing an individual gauging level, count the moirÚ fringe pulses fed to them when the piston is obscuring the scan spots at those levels. Unit 47 also supplies, for each level, a count representing the correct or desired width of the piston. By comparing the counts the piston is found to be of correct or incorrect size.
