Title: Sealed cell having contact cap permitting bulging of the housing when the internal pressure is excessive without failure of electrical contacts in a stack
Inventor: BRETT RONALD
IPC: H01M2/02
Filed: 1991-09-30
Abstract: In a cell eg. a round Ni-Cd cell2 comprising a sealed housing including two parts acting as terminals of the cell, one of the parts being provided with pressure relief device eg. a pressure relief valve, a contact cap 1 is mounted on the housing which leaves an intermediate space 3 between itself and the housing into which the housing can expand when the internal pressure becomes excessive. In a stack bulging of the housing can take place without failure of the electrical contacts. The fact that the housing walls have the possibility of expanding guarantees proper functioning in the response of the pressure relief devices, which are preferably located on the housing parts contained by the contact caps. The contact cap thus reduces the risk of cell explosions. The mechanical and electrical connection is maintained. <IMAGE>

Patent GB-921528-A (GB)
IPC: G01S7/10
Abstract: 921,528. Television. KAISER INDUSTRIES CORPORATION. April 6, 1959 [April 11, 1958], No. 11603/59. Class 40 (3). [Also in Groups XXXIII and XL (c)] In a cathode-ray tube (C.R.T.) display arrangement (see Group XL (c)) on an aircraft, the display is afforded by a signal generator feeding video signals to the grid of the C.R.T. in a monitor 146, the video signal generation is synchronized by line and frame pulses from timing generator 100, and the display produced includes sky and ground textures and a horizon line, Fig. 1 (not shown). Illustrations are given of further " still " displays showing the change of presentation with changing altitude, Fig. 2 (not shown), bank, Fig. 3 (not shown), and pitch, Fig. 4 (not shown). The line (H) pulses are fed to circuits 101, 102, 103, each of which generates a rectangular pulse whose trailing edges are delayed according to the instantaneous values of the outputs of pitch 109, azimuth 111, and altitude 113 sensors. Variation of delay varies the spacing between the columns of ground symbols in the display. Triangular waves are generated in circuits 105, 106, 107 in response to the trailing edges of the respective rectangular wave inputs; and the triangular wave generator outputs are commoned into mixing circuit 136<SP>1</SP>. Pitch sensor output signals directly coupled to the mixing circuit adjust the vertical position of the first symbol, and the output signals of unit 104 also operate to adjust the skew of the circle columns relative to the centre column as the pitch changes; this is accomplised by variation of the amplitude of a saw-tooth generated in unit 274 which is triggered by each frame (V) pulse. A mixer circuit 140 is controlled by the output signals of a " horizon " generator 138 and by the output of a " speed " oscillator circuit 144; in order to obtain separate symbol elements having motion indicating movement of the aircraft over the ground, the output of circuit 139 is modulated by pulses from oscillator 144, the shape of the oscillator pulses determining the shape of the symbols which form the paths. Elliptical, quadrilateral, or triangular shapes may be provided. The frequency of oscillator 144 is controlled by the speed sensor output. Adjustment of oscillator frequency to less than a multiple of C.R.T. raster vertical sweeps causes the symbols to move apparently from the bottom of the display towards the horizon to create the illusion of backward flight; this is useful in helicopters. Roll sensor 148 controls rotation of the C.R.T. deflection yoke. A flight path, Figs. 7 ... 10, 13 (none shown), may be displayed. Radar terrain sensing means affords a profile of the terrain lying ahead of the aircraft, Figs. 11, 20 (none shown). The display may be arranged to be in colour, with different colours for different " cue " symbols, Fig. 23 (not shown). Symbols repre. senting, e.g. ships may be utilized as alternatives to the elliptical symbols in the ground portion of the display, Figs. 25 ... 28 (none shown). The invention may be applied to other craft, e.g. a submarine, or to land or space vehicles.

Filed: 1992-07-29
Abstract: A component 110 which has a projecting spigot 112 for receiving a flexible tube 114 also has a protective cap 118 surrounding the spigot. If an excessive sideways force is exerted against the spigot 112, then the cap 118 prevents the spigot from moving beyond its elastic limit and thus helps to prevent the spigot fracturing from the component. <IMAGE>

IPC: F16K31/385
Filed: 1993-03-03
Abstract: A valve for use in a fire extinguishing system comprising a valve member 12 with a predetermined area on its inlet side exposed to the inlet pressure to produce a force tending to open the valve a larger area on its opposite, control side exposed to the pressure in a chamber 20 to produce a force tending to close the valve a passageway 32 through the valve member and a one-way valve 38 in the passageway 32 permitting fluid flow only from the inlet side to the control side of the valve member. The chamber 20 is vented to atmosphere when fire sensors 28 are activated, and the inlet pressure lifts the valve member 12 off its seat 10 to open the valve. The one-way valve 38 prevents unintentional opening of the main valve in the event of the temporary loss of inlet pressure. A weak spring 44 may urge the valve member 12 against seat 10. <IMAGE>

Title: Vapour air freshener device
Inventor: FORSTER JOHN TREVOR
IPC: A61L9/12
Filed: 1994-12-13
Abstract: An air freshener in the form of a cyclically movable mobile element such as the handle of a toilet cistern incorporating a perfume reservoir. The reservoir is in communication with an absorbant pad which when dosed with perfume, emits a perfume vapour to the surrounding atmosphere. In the normal position of the toilet cistern handle, the reservoir is out of communication with the absorbant pad, but when the handle is depressed, the perfume is fed to the absorbant pad through a constricted orifice such that a discrete amount of perfume is delivered to the absorbant pad which then evaporates to scent the air. The amount of scent emitted is, therefore, dependent on the number of cyclical movements of the handle. Emission of air freshening perfume is thus carried out on an automatic basis, in contrast to prior art air freshening devices and methods. <IMAGE>

Title: Procedure for calibrating the wheel speeds of a motor vehicle
Inventor: BAUMANN MATTHIAS
IPC: B60T8/172
Filed: 1995-05-10
Abstract: To compensate for differences in size of individual tyres, wheel speed measurements are automatically calibrated subject to certain conditions. The procedure is stated to be rapid and accurate and establishes wheel speed correction factors if:     i) the vehicle speed is above a set minimum speed; ii) the vehicle acceleration is between set positive and negative limits or the driving torque is within a specified range;   iii) no braking has occurred for a minimum period; and iv) effectively straight-line travel has occurred for a minimum period.   Straight-line travel is inferred if the time derivative of the left/right speed deviation of the wheels of at least the driven axle falls below a limiting value. The correction factors are established with respect to a reference speed, which may be the mean of the filtered wheel speed values. The factors may be adjusted incrementally.

Patent GB-2311918-A (GB)
Title: Audio signal decimation
Inventor: GREENWOOD JONATHAN MARK
IPC: H04N5/60
Filed: 1996-04-02
Abstract: NTSC signals have a frame rate of 29.97 frames per second. In SDI, audio data is sampled at a rate 30n where n is an integer, e.g. 48K samples per second. Thus there are 1601.6 samples per frame. Although there are an integer number 8008 samples per five frame sequence, two frames have 1601 samples and 3 frames have 1602 samples. This creates a variable storage requirements from frame to frame and causes problems in editing. The SDI audio data is separated from associated video and decimated by a factor h, where h = 4 for example in a signal processor 2, 3, 4, 5 and 6. The decimated data is written into a FIFO circuit 3 at the rate 30n over h synchronously with frame timing under the control of a frame reference generator 9. A fixed integer number n/h of samples is written into the FIFO in each frame under the control of a write control circuit 8. n/h = 400 for example, where n = 1600 and h = 4. Any additional sample in each frame is dropped. The 400 sample frames are stored on a disc 14. If it is desired to reproduce the samples, they are written into a FIFO 12. A read control circuit 13 reads the samples out synchronously with the video frame rate. In three frames 400 samples are read out: in two frames 401 samples are read out.
