Title: Altitude compensated continuous flow oxygen regulator
IPC: G05D7/01
Filed: 1959-06-08
Abstract: 865,084. Respiratory appliances. ARO EQUIPMENT CORPORATION. June 8, 1959 [June 9, 1958], No. 19479/59. Class 81 (2) An altitude compensated oxygen regulator has a secondary pressure reducing stage comprising a plurality of aneroid-operated valves disposed to function in parallel and operate in sequence. The secondary pressure reducing stage may comprise a plurality of sections in parallel, each section comprising a plurality of aneroid-operated valves disposed in parallel and operating in sequence. In an oxygen regulator for use in an aircraft, oxygen at high pressure, e.g. 2000 p.s.i., passes through a first stage reducing valve 38 into a chamber B, the valve being controlled through a lever 46 by a diaphragm D3 exposed on one side to the pressure in the chamber B and on the other side via a conduit 92 to the pressure in an outlet chamber C of the device. The diaphragm D3 is urged by an adjustable spring in a direction tending to close the valve 38. Two secondary stage reducing valves 54, 54a arranged in parallel connect the chamber B with the outlet chamber C. Each secondary stage valve is controlled through a plunger 74, 76 and a diaphragm D1, D2 by an aneroid capsule A1, A2 disposed in a housing connected to the ambient atmosphere through a vent 84. The plungers bear against their respective diaphragms which are exposed to pressure in the outlet chamber C. The ratio of the effective areas of the aneroid capsule and the diaphragm associated with each secondary stage valve is such that as the ambient pressure falls due to an increase in altitude, a first secondary stage valve 54 only will open at lower altitudes, the second secondary stage valve 54a only opening at higher altitudes at which the first secondary stage valve will be closed by additional pressure acting on its controlling diaphragm. The first stage pressure reducing parts are contained in a housing mounted on a base 16 and are connected by conduits formed in the base with one section or several having sections arranged in parallel, each section containing a pair of secondary stage reducing valves and their associated parts. One or more secondary stage sections, each having an outlet 110 from its outlet chamber C for the connection of respirators, are used, dependent on the number of passengers to be supplied with oxygen. The aneroid housing vent 84 may be connected to a vacuum line for testing the operation of the device.

Title: Improvements in or relating to Demodulators for Frequency Modulated Signals
IPC: H04L27/14
Filed: 1967-04-28
Abstract: 1,182,508. Frequency discriminators. SIEMENS A.G. 28 April, 1967 [29 April, 1966], No. 19597/67. Heading H3A. In a frequency discriminator for demodulating frequency shift telegraphy signals, the input is amplified and limited in unit B to derive a square wave U1 the rising and falling edges of which synchronize respective pulse generators G1 and G2 operating at a common frequency greater than the channel centre frequency; the signal U s  from generator G1 operates an electronic switch S1 which allows the output signal U2 from generator G2 or its inverse to pass through the filter TP to output terminal U4. The frequency of generators G1 and G2 is fixed relative to the operating frequencies so that when the input is at its highest frequency the signals U s  and U2 are in phase (Fig. 3a, not shown) thereby producing a positive output signal; when the input is at the channel centre frequency (Fig. 3b) the signals U s  and U2 are in phase quadrature giving a zero output signal; and when the input is at its lowest frequency (Fig. 3c) the signals U s  and U2 are in anti-phase giving a negative output signal. In one practical arrangement (Fig. 4, not shown) the generators G1 and G2 comprise resonant circuits shockexcited through oppositely poled diodes from a differentiating circuit fed from the amplifier B, the resonant circuits feeding amplifier-limiter circuits. In another arrangement (Fig. 5, not shown) suitable for construction as an integrated circuit, the generators G1 and G2 are RC oscillators feeding amplifier-limiters which each provide two anti-phase outputs. The two output lines from generator G2 are connected to an output terminal (A) and are shunted by a pair of transistors (TS16 and TS17) controlled by the two outputs from generator G1 so that one transistor conducts and the other is cut off, this circuit being equivalent to a ring modulator.

Title: Digital sine wave synthesizer calculator
IPC: G01C19/04
Filed: 1975-05-12
Abstract: 1508377 Digital sinewave generators UNITED TECHNOLOGIES CORP 12 May 1975 [13 May 1974] 19795/75 Heading H3H An approximation to a sinewave is generated by stepping a main counter 120 up and down between the peak values, the rate of stepping being progressively decreased as the peaks are approached and increased as the peaks are left behind. In Fig. 5 when the state of counter 120 is between values representing  sin 60 degrees gate 122 passes every clock pulse from source 124 to the main counter 120. When this range is exceeded, a gate 144 is enabled whereupon a 4-bit "slope" counter 148 is decremented at 1/16 the clock rate, each decrement controlling gate 122 to stop out one extra clock pulse from the next 16 until all are stopped when the slope counter 148 empties at the sine wave peak. Logic 154 reverses the counting direction of both counters whereafter a progressively larger proportion of the clock pulses reach counter 120 as counter 148 is incremented; and so on. Thus the output varies linearly with time between the sin 60 degree values and in a segmented parabolic manner in the region of the peaks. Counter 120 may contain a positive bias. The output is fed to a digital-to-analogue converter (not shown) and may be used to sinusoidally modulate the angular momentum of a gyroscope. A square-wave signal is output on line 164.

Title: New or improved means for suppressing surge in liquid pumping mains
IPC: F04D15/00
Filed: 1947-07-25
Abstract: 631,986. Valves controlled by auxiliary valves. BLAKEBOROUGH & SONS, Ltd., J., and BROTHERTON, C. July 25,1947, No. 20005. [Class 135] Means for suppressing surge in a liquid pumping main comprises, in a branch b, Fig. 3, from the main, a surge-suppressor valve, which may be of the Larner-johnson type, normally held closed by mains pressure admitted through a solenoid-operated rotary valve d and a leveroperated valve e beneath an operating piston, and arranged to open when the pump stops. When the pump stops, the solenoid valve cuts off the pressure supply to both the operating cylinder c and timing cylinder f and connects both cylinders to the exhaust-pipe j, liquid from the cylinder f passing through a regulator valve i and from the cylinder c through the valve e. The operating piston is heavily loaded at c<SP>1</SP> and descends quickly to open the suppressor valve and discharge water from the main. The rate of descent of the timing piston, less heavily loaded at f is such as to allow stable conditions to develop in the main. As it descends, an abutment k engages a lever e<SP>1</SP> to move the valve e so that pressure raises the operating piston and closes the suppressor valve, the speed of closing being controlled by a pressuresupply regulating valve m. The timing piston remains at the bottom of its stroke until the pump restarts, whereupon the solenoid valve allows pressure through the check-valve g to raise the timing piston and restore the valve e to its original position. In the modification shown in Fig. 4, a second timing cylinder m<SP>1</SP> is provided when it is not desired to open the suppressor valve immediately the pump stops, the piston being normally raised by the mains pressure. When the pump stops, the solenoid valve d allows the main timing piston to descend at a rate determined by the valve p to actuate through a lever n<SP>1</SP> a valve n which allows the operating piston to descend and open the suppressor valve. Simultaneously the second timing piston is allowed to descend when the valve r is actuated by the main timing piston through a lever, the descent being controlled by the valve s. The second timing piston then actuates a lever-operated valve t which readmits pressure below the operating piston to close the suppressor valve. When the pump restarts, the solenoid valve allows the main timing piston to rise and return the valves rand n to their original positions, the valve r thus allowing the second timing piston to rise.
