Title: Improvements in or relating to boiler feed regulator valve mechanisms
Inventor: WOOD GEORGE
IPC: F22D11/00
Filed: 1954-04-02
Abstract: 770,954. Fluid-pressure servomotor control systems. VICKERS-ARMSTRONGS (ENGINEERS), Ltd. March 10, 1955 [April 2, 1954], No. 9706/54. Class 135. A feed water-regulator valve for steam boilers is connected at 5 to the feed water pump and at 3 to the boiler and encloses a slidable valve member consisting of a closure element 7 coacting with a seat 4a and a piston 8 above which is a pressure chamber 2a in which a variable control pressure dependent upon the liquid level in the boiler and set up by the operation of a gear motor 11 and gear pump 12 is effective on the piston 8. The gear motor 11 is fed from the inlet to the regulator through a pipe 15, an adjustable valve 14, and conduit 13 and it discharges through a passage 17 leading to the outlet 3. The pump 12, which is directly driven by the motor 11, has an inlet 18 connected to the boiler at the liquid working level and a restricted outlet 19 to the outlet space 9 of the motor. The arrangement is such that when the liquid level in the boiler is below the working level steam is pumped by the pump 12 resulting in a comparatively low pressure drop across the motor 11 with consequent low pressure above the piston 8 allowing the valve to be opened by inlet pressure. When the water level in the boiler is above the working level and the pump 12 is pumping water, putting a greater load on the motor 11, the pressure drop across the motor is greater resulting in sufficient pressure in the chamber 2a to close the regulator.

Title: Sound detectors
IPC: G01S3/82
Filed: 1974-11-27
Abstract: 1487364 Sound direction detectors MARCONI CO Ltd 27 Nov 1974 [6 March 1974] 9954/74 Heading G1G The direction of a sound source is detected by an array of omnidirectional microphones Fig. 1, wherein, the elements of each pair AB and CD are connected together in phase opposition such that an output signal is produced when the detected sound is in a direction other than that normal to the line joining a pair. In Fig. 3, from each pair of so-connected microphones, two difference signals are derived in phase opposition and applied respectively to a modulator 1, 2, 3, 4. A frequency source 5 generates a low frequency reference signal which is phase shifted by shifters 6, 7, 8, 9 to a degree corresponding to the relative phase shifts of the signals applied to the modulators (pair CD being in phase quadrature with pair AB) and modulates the higher frequency difference signals, which modulated signals are combined at 14. The phase of the combined signal is analogous to the rotating polar diagram of microphone sensitivity 15. Microphone E produces an omnidirectional response signal, which may be phase shifted at 17 to compensate for any overall shift in modulators 1-4, and which when subtracted from the signal from each microphone pair produces an effective cardioid pattern Fig. 2, (not shown). The signal from E is subtracted from the combined signal in comparator at 16 to produce effectively rotating cardioid pattern 18, which results in an effective cartesian co-ordinate response: 1 + cos(wt + °) where w is the reference angular frequency and ° is the angle of the sound direction relative to to some datum e.g. north. ° is detected in phase comparator 19 and the direction is displayed at 20, e.g. on a C.R.T. For sounds of short duration, the C.R.T. can incorporate a storage facility to enable the direction to be measured by the operator.

Title: Means for controlling electronic discharges and devices making use thereof
IPC: H01J25/16
Filed: 1940-06-07
Abstract: 541,631. Cathode-ray tubes. STANDARD TELEPHONES & CABLES, Ltd. June 7, 1940, No. 9976. Convention date, June 15, 1939. [Class 39 (i)] Electron discharge apparatus for use as a detector, amplifier, oscillation generator &c. comprises means for providing a magnetic field, a beam of electrons in the direction of the magnetic field and having velocities transverse thereto and a transverse highfrequency electric field, whereby the beam of electrons is separated into two groups having differing transverse velocities. Means, such as a diaphragm electrode, or a reflecting electrode allow a selected group to pass through a further transverse high-frequency electric field for the abstraction of energy from the beam. Preferably the beam of electrons originates from an annular cathode and is formed into a cone by a focusing electrode . Apparatus embodying the invention is shown in the drawing. An envelope 50 has a tubular body part with two pairs of oppositely disposed arms 51, 52 and 53, 54. Sleeves 61, 62 are disposed across the pairs of arms and have aligned apertures 64... 67. Dielectric guides, such as 56 are sealed to the ends of the arms by insulating members 57 with a partition 59 and internal conducting coating 60. A circular thermionic cathode 69,, shield 70 and diaphragm 71, electrically connected and mounted on the sleeve 61 in abutment with the apertures 64...67, provide the beam of electrons along the direction of the magnetic field represented by pole pieces 80, 81. A tubular electrode 68 mounted in the tubular part of the envelope, reflects one group of electrons, and the other group is collected by the electrode 77. The incoming signal, represented at 82, sets up a high-frequency electric field across the sleeve 61 ; and the output signal is transmitted at 83. The device may be tuned by reflecting pistons 84, and feed-back coupling obtained by the Lechner wires 86, or by a second beam of electrons transversing the envelope in the reverse direction.

The breaker is withdrawn for isolation by rotation about pivot 12 by means of a linkage 17, 18, the common pivot of which is engaged by a cam 19 operated by a handle 20, the lever 15 being then actuated upwards from the position shown to change the busbar-connections. The weight of the structure is counterbalanced for horizontal and vertical movement by springs 24, 23, respectively operating in tension and compression, and the breaker is itself actuated by the handle 21 and flexible cable 22. The cable contact 7 is engaged by either limb of the lower contact 9.

Title: Fsk discriminator
Inventor: HUGHES PATRICK MICHAEL
IPC: H04L27/14
Filed: 1996-07-18
Abstract: The outputs of two filter channels for accepting two keying frequencies are compared to produce the output. Each channel uses finite impulse response transversal filters; preferably with an impulse response of duration comparable with the symbol period of the incoming signal. Each channel has a pair of filters for accepting phase quadrature components (or, alternatively, quadrature synchronous demodulators followed by filters): the filter coefficients differ from sinusoidal by (or, in the alternative case, are formed by) a modification function which is the same for both filters of the pair.
