Title: Pressure regulating mechanism applicable, for example, to pressurised aircraft cabins
IPC: B64D13/02
Filed: 1951-03-02
Abstract: 700,870. Fluid-pressure servomotor control-systems. GARRETT CORPORATION. March 2 1951 [March 20, 1950], No. 5139/51. Class 135 Mechanism for regulating the pressure in pressurized enclosures, e.g. aircraft cabins, comprises a control pressure chamber 27, pressure responsive means 31 for controlling the pressure in said chamber, said means having predetermined response characteristics, means for yieldably loading said pressure responsive means to thereby give said means different response characteristics, and lock-out means for rendering said loading means ineffective to give said pressure responsive means said different characteristics, so that the pressure responsive means will function in accordance with said predetermined characteristics. The outflow of air from the cabin 10 is controlled by a valve 12 comprising closure members 16 actuated by a diaphragm 23 subject on opposite sides to cabin pressure and the pressure in the control chamber 27. Air enters the control chamber through an orifice 27a and is bled off under the control of pilot valves 28, 29. The valve 28 is actuated by an evacuated bellows 30 and serves to maintain the cabin pressure substantially constant up to a predetermined altitude. Above this altitude, the valve. 29 operates to hold a predetermined differential between cabin and atmospheric pressures, and is actuated by the pressure responsive means in the form of a diaphragm 31 subject on opposite sides to atmospheric pressure via a pipe 39-and the control chamber pressure. The closure member 46 of valve 29 is carried by a yoke 42 attached to the diaphragm 31 and having an upstanding boss 41, and the differential pressure may be set by adjusting a spring 49. The yieldable loading means comprises a spring 55 arranged to be applied to the boss 41 at will by the pilot to reduce the differential pressure to a predetermined low value, e.g. when the aircraft is entering combat. The spring is locked out of engagement with the yoke by a lever 61 pivoted at 62 and actuated through a rod 65 by a diaphragm 66 loaded by a spring 91 and subject on its opposite sides to control chamber pressure and the-pressure in a chamber 71. Cabin pressure leaks into the chamber 71 through an orifice 72 and is exhausted to atmosphere through a normally open, solenoid-operated valve 80, whereby control chamber pressure holds the diaphragm 66 against its spring to retain the spring 55 away from the boss 41. To lower the differential pressure, the pilot operates a switch to close the valve 80, thus causing pressure to build up in the chamber 71 whereby the spring 91 moves the diaphragm 66 and hence the lever 61 to permit the spring 55 to engage the boss 41. Specification 655,601 is referred to.

Title: Improvements in photo-electric gauging apparatus
IPC: G01B21/08
Filed: 1945-03-02
Abstract: 588,679. Photo-electric gauges. BRITISH THOMSON-HOUSTON CO., Ltd., and HIBBERD, R. G. March 2, 1945, No. 5277. [Class 40 (iii)] [Also in Group XXXVIII] In a photo-electric linear dimension gauge, wherein the light incident on a photo-cell 15 from a source 14 controlled by a shutter 12, operated by a plunger 7 biassed towards engagement with the part 3 to be gauged, the cell output is amplified in a thermionic valve and indicated on a centre-zero meter 10 arranged to indicate the magnitude and sense of the deviation of the test piece from a standard. Two opposing currents pass through the meter 10, the valve-anode-current, and a backing-off current passing from battery 18 through resistance 9, meter 10, plunger 7, and test piece 3. With a standard piece in the gauge these two currents are balanced by adjustment of resistance 9 and if necessary resistance 11. With a test piece in the gauge any variation in the light incident on the cell 15 varies the potential drop across resistor 16 and hence the anode current, the meter deflection indicating the dimensional deviation, plus or minus, directly or the degree of deviation. Since both currents through the meter pass through the test piece the meter circuit is broken when the gauge is not in use. The valve amplification may be adjustable to vary the meter sensitivity.

Title: Improvements in pulse shortening circuit
IPC: H03K5/04
Filed: 1950-03-03
Abstract: 676,328. Pulse shortening circuits. TELEFONAKTIEBOLAGET L. M. ERICSSON. March 3, 1950 [March 3, 1949], No. 5439/50. Class 40 (vi). In a pulse shortening circuit the input pulse is applied directly and via a phase inverting and delaying means to a mixer circuit comprising two parallel connected valves so that an output pulse is produced whose duration is determined by the delay time of the delaying means. The negative going input pulse at terminals 1, 2 is applied directly to grid 13 of the double triode valve to cut-off the left-hand section so that the potential of anode 14 rises and is held at this level until the delayed positive going pulse applied at grid 12 via the phase inverting stage 4 and delay network 8 causes the right-hand section of the valve to conduct hard, thus lowering the potential of anode 15. A positive going output pulse is thus produced across load 16 the duration of which is determined by the delay introduced by network 8.

Abstract: 1,113,895. Periodic counters. FERRANTI Ltd. Feb. 7, 1967 [Feb. 8, 1966], No. 5528/66. Heading G1K. A maximum demand meter comprises a train of counter wheels 11, 12, 13, driven in dependence on electrical energy consumption, and a train of auxiliary wheels 21, 51, 61. These are driven through differential gears 22, 52, 62 by the wheels 11, 12, 13 when the demand in a period overtakes that in any preceding period, but are locked at all other times. The locking means comprise arms 33 on a shaft 34 urged by a spring 38 to hold detents 32 against cam surfaces 28 secured to the cages 27 of the gears 22, 52, 62 while detents 37 engage notches 36 in the wheels 21, 51, 61. In this position of the arms 33 the cages 27 of the gears are driven by the wheels 11, 12, 13 while they themselves are being driven and while they are being periodically reset under the control of a timer 46 and the wheels 21, 51, 61 remain locked. A detent 32 can only enter the notch in its associated cage 27 when the notches in all their cams are aligned and, after the initial period, this occurs only when the demand in a period reaches the previous maximum. Then the detents 32 engage the notches 31 to lock the cages and the detents 37 free the wheels 21, 51, 61, to be driven by the wheels 11,12,13 through the pairs of sun-wheels. At the end of such a period when the timer 46 closes contacts 42 and a solenoid 41 is energized it rocks the shaft 34 to move the detents 37 into the notches 36 of the wheels 21, 51, 61 in register therewith and closes the contacts 44 to operate the reset mechanism. At the end of other periods the wheels 21, 51, 61 are already locked and the contacts 44 closed, so that the closing of contacts 42 merely initiates resetting. Supplementary wheels are also envisaged to which the readings of the auxiliary wheels are transferred at the end of an accounting period when the auxiliary wheels are reset manually, the operation of a reset lever providing a one way drive for this purpose.
