Patent GB-1288118-A (GB)
IPC: G01C19/5691
Filed: 1970-07-02
Abstract: 1288118 Turn sensitive devices GENERAL MOTORS CORP 2 July 1970 [18 July 1969] 32079/70 Heading H4D [Also in Division G1] Rotation of a high-mechanical-Q member about an axis therethrough is detected by imparting radial vibrations to the member, the vibration pattern having a null region in the absence of rotation, and sensing radial vibrations produced at the site of the null region as a result of any rotation of the member. In the Fig. 4 embodiment, for use in an inertial navigation system, the member is a bell B supported by stem S on a plate 42 adjustably clamped to platform P. Radial vibrations (e.g. at 1600 Hz) of the bell are maintained by drive transducer E, pickup transducer X and amplifier 94. Transducer R is positioned at a vibration node and detects radial vibrations of the bell generated by Coriolis forces if there is any rotation of the bell about axis Z-Z. Transducer E is an electrode which drives the bell by electrostatic forces. Transducers X and R are screened electrodes which define with the bell capacitances which vary with the radial vibrations, the capacitance variations being arranged to amplitude-modulate carrier waves (e.g. of 50kHz). The modulated waves are amplified, rectified and then filtered at 84, 102 to provide two demodulated signals at the bell vibration frequency and of amplitude representing the vibration amplitude. The signal from 84 drives amplifier 94 and also provides a reference signal for a phasesensitive amplitude-detector 106. The amplitude and phase of the signal from 102 relative to this reference are detected at 106 and represent the rate and sense of the bell rotation. In another embodiment (Fig. 3, not shown), pickup transducer X is omitted and transducer E is driven by an oscillator whose frequency is adjusted for resonance of the bell. This adjustment, and optimizing of the transducer positions, are assisted by monitoring the oscillator signal and transducer R signal on a dual-beam oscilloscope. In modifications, bell B may be replaced by some other hollow or solid vibration-sustaining member, e.g. in the form of a ball, a ring, a disc, an eight-sided crystal, or an irregularlyperimetered plate mass-balanced along the directions of vibration.

Title: Method and apparatus for detecting the presence of at least one specified gas

Abstract: 1,121,853. Gas analysis; testing for leaks. NATIONAL RESEARCH DEVELOPMENT CORP. Nov. 5, 1965 [Aug. 7, 1964], No.32182/64. Headings G1B and G1S. In a method of detecting the presence of a specified gas e. g. helium one face of a membrane which is permeable to the specified gas and substantially impermeable to other gases is exposed to a sample of the gas under test whilst the other face of the membrane is exposed to the evacuating system of a mass spectrometer set to detect the presence of the specified gas. The method may be used to detect the presence of leaks in a closed container which is filled with the specified gas any leaks in the container allowing escape of this gas and thus enabling detection by use of the mass spectrometer. In Fig. 2 the membrane 15 which is of polyethylene terephthalate is folded and tucked into a slot 14 cut in a hollow brass member 11, the membrane being sealed to the edges of the slot by a cold setting cement. A connection 12 lends to the evacuating system of a mass spectrometer (not shown). Two brass tubes 16, 17 disposed as shown and provided with apertures 20, 21 are placed in the fold of the membrane and sample gas is drawn over the membrane, entering via the tube 16 and aperture 20 and leaving via the aperture 21 and tube 17 which is connected to a small pump. Helium in the gas sample will diffuse through the membrane and will be detected by the mass spectrometer. The tube 16 or an extension thereof may be used as a probe and may be passed over the outside surface of a vessel filled with helium and which it is desired to test for leaks. In an alternative arrangement the membrane is not folded but is held between a recessed block connected to the mass spectrometer and a sealing plate and inlet and outlet connections for a gas sample.

Abstract: 1,020,481. Nuclear power plant. ENGLISH ELECTRIC CO. Ltd. Aug. 28, 1962 [Sept. 8, 1961], No. 32272/61. Heading G6C. An alarm analysis system for a power station comprises a plurality of section analysers each responsive to faults occurring in an associated section of the power station equipment for determining the corrective action required upon the occurrence of one or more faults, and a master fault analyser for assessing at least some of the corrective actions determined by the section analysers and for assigning an order of priority to such corrective actions. In the arrangement shown there are seven section analysers SA1-SA7, each of which monitors the operation of part of the power station, e.g. SA1 monitors the nuclear reactor 10, the fuelling machine 11, and the effluent treatment plant 12. The section analysers are each arranged to respond to faults and to give output signals which in turn operate apparatus which gives indications of the appropriate operator action for correcting the fault, and at least some of the output signals of each section analyser are also fed to a master analyser MA. The master analyser determines whether there is any conflict in the instructions given by the section analysers, which may happen if two unrelated faults occur simultaneously, and the master analyser then determines the appropriate operator action.

Abstract: 1515747 TDM switching J DUQUESNE M ROUZIER M REVEL and O LOUVET 5 Aug 1975 [30 Aug 1974] 32711/75 Heading H4K A switching unit controls the transfer of both intelligence and signalling information between incoming and outgoing pcm TDM highways I & O. Intelligence and signalling information are transmitted in different formats and at different rates, and hence are written into different stores-6 and 7 respectively - at these respective rates. In order that both may be read out of the stores at the same rate, signalling information is read out of the signalling store 7 not only during a signalling time slot but also during one or more time slots which are not used for intelligence, e.g. synchronizing time slots. A delay arrangement, Fig. 6 (not shown) ensures that signalling information read out during a "spare" time slot is only transmitted along an outgoing highway during its appropriate signalling time slot.

Class 39(1) [Also in Group XXXVI] A switching device, particularly for use with an electroluminescent display device as described in Specification No. 888,433, comprises a layer 12a of electroluminescent material having a set of conductors 11a, 13a disposed on each face thereof in directions transverse to each other, and a plurality of photo-conductive cells each associated with the intersection of a different pair of conductors, each of the cells being provided with connecting leads 19, 20 by which they can be connected to external circuits 21 whereby a plurality of circuits can be selectively controlled, each by a different photo-conductive cell when energised by illumination thereof by fluorescence of the electroluminescent material at the associated intersection of conductors under the influence of signals applied to the conductors. The device can comprise a supporting plate 10a of glass on one face of which the set of conductors 11a, which are at least partially transparent, is printed, and on the other face of which the electrodes 17, 18 of the photo-conductive cells can be printed. The electrodes of the photoconductive cells can be formed by indium soldered to the plate by a tin/indium solder, and a layer of cadmium sulphide 16 can be provided as a photo-conductive layer overlying each pair of electrodes. The thickness of the plate can be so thin compared with the spacing of the intersections of the conductors and cells that fluorescence of the electroluminescent material at any one intersection of conductors is only effective to illuminate the associated cell, the illumination which would otherwise affect the adjacent cells being totally internally reflected within the plate. The cell circuits of the switching device shown in Fig. 2 can be energised by A.C. and used for controlling the crossed-conductors electroluminescent display device of Fig. 1. The ratio of the capacity of the two cells concerned to the capacity of the electroluminescent element involved should not exceed <SP>1</SP>/ 5  which is achieved by employing as thin a layer of phosphor as possible. As shown in Fig. 5 the conductors of the arrangement of Fig. 2 can be selected by the use of two further devices 22 and 23 constructed in accordance with the invention.
