Title: Improvements in or relating to pneumatic pressure output relays
IPC: G01F1/38
Filed: 1958-04-14
Abstract: 892,056. Fluid-pressure servomotor-control systems. BAILEY METERS & CONTROLS Ltd. April 14, 1958 [April 12, 1957], No. 11870/58. Class 135. In a process controller having a nozzlebaffle pair and an associated negative feedback bellows or diaphragm the nozzle back pressure is not transmitted directly to the bellows or diaphragm but via a relay having proportional plus integral action. In the first example, Fig. 1, the controller 1 is responsive to changes in flow in a line 3 and adjusts the diaphragm operated regulating valve 6 in line 7. The pressure drop across the orifice 2 is reflected by the diaphragm 12 which is connected via a link 21 and a sealing diaphragm 23 to a balance beam 22 which carries a baffle 24 which cooperates with a nozzle 25. The nozzle back pressure is transmitted to a relay 35 the output signal from which is fed to the diaphragmoperated valve 6 and to a feedback bellows 32 which acts on a beam 30 carried by springs 31 and abutting a settable nut 29 on a screwed rod 28 carried by the beam 22. The relay 35, Fig. 2, comprises a four part body 41-44 supporting three diaphragms 46, 47, 48, which define chambers 49-52 and which are rigidly connected by a member 45 loaded by a spring 53 in the chamber 52. The chamber 51 has an exhaust port. The chamber 52 is connected to the nozzle 25. A valve spindle 62 having two closure members 61, 63 is controlled by the member 45 to discharge air from the chamber 52 via the valve 61 or to admit air to the chamber 52 via the valve 63. The chamber 52 is connected via an orifice 70 to the positive feedback chamber 49 so introducing integral action. The pressure in the chamber 52 is reflected in the bellows 32, Fig. 1, and constitutes the relay output signal. In another example, Fig. 8, changes in a variable condition are transmitted via links 303, 301, and a screw 312 to a baffle 315. The nozzle back pressure is transmitted to a relay 310 which is similar to the relay 35 of the previous embodiment and the output signal from which is fed to the line 319 and to a feed back diaphragm 306 which acts on the lever 301. In another example, Fig. 9, a change in a variable pressure is detected by a Bourdon tube 401 which is connected via a link 402, a pointer 403, a link 404 to a lever 405 carrying a baffle 406 which co-operates with a nozzle 407. The nozzle back pressure is fed to a relay 413 the output signal from which is led to indicating and/or recording and/or regulating means and to a feedback bellows 410 which acts on a lever 408 carrying the nozzle 407 and connected by a link 411 to a pointer 412.

Title: Improvements in or relating to air-brake systems
IPC: B60T17/00
Filed: 1930-04-15
Abstract: <PICT:0352972/III/1> Compressed air for air-brake systems is dried by passage through a mass of porous adsorbent material such as silica gel.  The deposition of frost or ice in or adjacent the triple valves which would prevent the proper working of these is thus prevented. The arrangement shown in the Figure comprises two containers 26, 26a each containing a cartridge of the adsorbent material one or the other of which is in use while the other is being reactivated. With the valves 30a, 31, 28c, 32c, 34, 35 in the position shown, the air supplied by the compressor to the main reservoir 13 flows through a separator 16, to separate condensed water and oil, and the container 26 of adsorbent material to the main pipe 32 of the brake system. Meanwhile heated air is drawn by a fan S through a heater 36 and the other container 26a to reactivate the adsorbent material therein.  By adjusting the valves the air from the reservoir 13 may be passed through the container 26a and the heated air through the container 26.  The heating medium for the heater 36 may be hot gas from the locomotive smoke box or steam from the locomotive.  The silica gel may be produced as described in Specification 136,543, [Class 1 (i), Chemical processes &c.], or instead of this, the gels of the oxides of tin, aluminium, titanium or tungsten or gels comprising one or more of these with or without silicon oxide may be used.

Patent GB-580891-A (GB)
Title: Improvements in and relating to time base generators for cathode ray tubes
IPC: H03K4/20
Filed: 1944-06-28
Abstract: 580,891. Saw-tooth generating circuits. DEBSKI, J. M. June 28, 1944, No. 12251. [Class 40 (v)] In a saw-tooth time base generator, in which a rectangular pulse is applied to a valve having a condenser connected between anode and control grid to produce the saw-tooth output, a modifying potential is applied to one or more electrodes to modify the generator output. The modifying potential may be applied to the control and/or screen grid and may expand or contract the time base. The anode current of Miller time base valve V is normally zero due to bias on the suppressor grid, but upon a positive square wave being applied over coupling condenser C1, the suppressor grid rises to earth potential, allowing anode current to flow and the anode potential to fall linearly as condenser C discharges to generate the time base voltage. Upon an additional positive pulse being applied over coupling condenser C2 and variable resistance R2 to resistance R3, diode V1 conducts, increasing the rate at which the grid potential of valve V rises and hence the rate of discharge of condenser C. At the cessation of the additional pulse, the condenser C discharges at the previous rate. In a modification, Fig..4 (not shown), the additional pulse is also applied to the screen grid and may be negative to contract the time base. A tetrode operating with low screen voltage may be used in place of the pentode, the main pulse raising the screen potential to an operating value. A variable delay network may be inserted between the pulse generator and the valve V to allow adjustment of the commencement of the expanded portion of the time base.
