Patent GB-2009564-A (GB)
Title: Telephone exchange apparatus providing short dialling
IPC: H04M3/44
Filed: 1978-12-06
Abstract: Address converter (V1, V2, V3) is used for addressing a short-dialling store (KW) on the basis of a calling subscriber's switching network terminal address which depends on a switching network classification into switching network units (KGABC1, KGAB1). The store can then emit a complete called subscribed number in response to a short dialling number transmitted by a calling subscriber. To keep down outlay a portion (V1, V2) of the converter is used in common both for addressing a main subscriber data store (TH) required for all subscribers and the short- dialling store. The converter provides branching of the addressing operation at a portion (V2) dependent on the classification of the switching network. A further portion (V3) is used for addressing the short dialling store in conjunction with a short-dialling number. The allocation of storage positions to a subscriber within the short-dialling store can be fixed variable to suit subscriber numbers of varying sizes. <IMAGE>

Patent GB-2014834-A (GB)
Title: Improvement in or relating to sprayers
IPC: A01G25/09
Filed: 1979-01-30
Abstract: A sprayer for use within agriculture has an elongate spraying boom (15) on an adjustable holder (10) on an agricultural vehicle. The spraying boom (15) and holder (10) are interconnected by the intermediary of a connecting shaft (14) and a supporting arm (23) which is pivotal on the spraying boom and whose angle with respect to the boom may be adjusted by means of a hydraulic piston and cylinder assembly. The connecting shaft (14) is perpendicular to the plane of the boom (15) and is disposed in spaced apart relationship above the centre of gravity of the boom. By regulating the angle of the supporting arm (23) with respect to the spraying boom (15), it is possible to adjust the positioning of the spraying boom in relation to the plane of the ground. For damping oscillation of the boom (15), the boom and the holder (10) are, moreover, interconnected by means of an oscillation damper (29). The oscillation damper is in the form of a double-action piston and cylinder assembly whose both cylinder ends are interconnected by the intermediary of a conduit which may be throttled. <IMAGE>

Patent GB-2046445-A (GB)
Title: The measurement of stopping times particularly of industrial machines
IPC: G04G21/08
Filed: 1979-04-11
Abstract: To measure the stopping time of an industrial machine it is desired to produce a timing signal at the instant when a stop button/switch is first touched by an operator. This will not necessarily be simultaneous with the operation of the stop button contacts. In the invention a touch switch A, affixed to the stop button surface (not shown in Figure 6) e.g. by contact adhesive, has two interdigitated electrodes 74, 75 on an insulating substrate 76. One electrode is earthed, as is a backing sheet 77, this arrangement reducing the risk of false actuation. The touch switch A is operated by a thimble B attached to the finger of an operator and including a metal cup 78 and a conductive soft foam rubber pad 79. The use of this thimble B eliminates problems which would otherwise arise from contamination of the electrodes 74, 75 by grease, etc., on the operator's finger; and from differences in conductivity of his finger depending on moistness, etc. <IMAGE>
Patent GB-2030392-A (GB)
Title: Analog-to-Digital Converter Apparatus for Condition Responsive Transducer
IPC: H03M1/52
Filed: 1979-07-27
Abstract: An analog signal VA representing the measured output of a condition responsive transducer is supplied to a dual slope integrating analog-to- digital converter 12 also receiving a regulated constant reference signal VA from which a signal Vmax is derived. Using an integrator 18 in a non- inverting mode, the A/D converter in sequence first integrates (Vmax-VA) for a fixed time period Tr and then integrates the sum of the first integrated signal and the reference signal VA for a variable time period TX down to VR as detected by a comparator 20. During integration, digital counts VD proportional to the variable integration period are accumulated and emitted for operating a digital device such as a digital display. Digital linearization of the converter output can optionally be provided by use of a programmed micro-computer reading a programmable-read-only- memory (PROM) to run a variable frequency clock. The clock is regulated to effect a first phase converter time corresponding with an even multiple of the power line frequency. <IMAGE>

Title: Pick-up tube having light pipe
IPC: H01J31/38
Filed: 1979-10-16
Abstract: Light conductor 28 in pick-up tube 10 transmits light from a light source (e.g. filament 20) to target 24 for biasing the dark current of the target, the light passing through conductor 28 being selectively modified so that the illumination and hence dark current of the target can be controlled. Modifications can be by roughening the end portions 36, 38 of the rod (also Figures 4a, b not shown), the stem 30, or branches 32,34. Other modifications are detailed w.r.t. Figures 5a to 8b (not shown). Single shaft conductors, Y-shaped conductors, and internally or externally mounted light sources may be used. Light conductor rod materials and dimensions are disclosed. The inner surface of anode G3 scatters light due to roughening target materials are specified e.g. PbO sensitised with H2S to extend the red sensitivity. The arrangement can reduce the problem of bias dark current deviations in tubes within a batch. <IMAGE>

Title: Digital video processor
IPC: H04N1/64
Filed: 1980-03-04
Abstract: Spatially adjacent lines L1, L2 of a digital television signal (sampling rate 4 fsc) are separated 40, 41 into high and low frequency components, the high frequency components are averaged at 42 and selected portions of the average are combined 47, 49 with selected portions of the low frequency signal corresponding to each line whereby the bit rate is halved (switches 43, 44 and 46 are each operated at 2 fsc). Recovery of a 4 fsc signal is by adding the averaged high frequency components of spatially adjacent lines to the low frequency component for each line. An application is the formation of a disc store of photographic slides or frozen video frames, and reference is made to the control of picture shape, size and orientation to cross-fading, and to the production of a composite picture of a number of stored pictures. <IMAGE>
Patent GB-2044091-A (GB)
Title: Mattress
IPC: A47C31/12
Filed: 1980-03-05
Abstract: A mattress for supporting the human body has shoulder-supporting and hip-supporting portions 5, 6 of less hardness than waist-supporting and foot-supporting portions 4, 7. The hardnesses of the shoulder-supporting and hip-supporting portions are inter-related to the maximum hardness of the waist-supporting portions so that the mattress biases the spine of the user into a shape consisting of two concave curves separated by a convex curve, which gives a more comfortable mattress and has medical and orthopaedic advantages. The mattress may comprise steel springs, or a foam plastics material which may be apertured, as at 9..11, or consist of regions of different bulk densities. <IMAGE>
Patent GB-2072830-A (GB)
Title: Stove grates
IPC: F23H15/00
Filed: 1980-03-26
Abstract: A grate is composed of bars G each pivotally supported eccentrically to its centre of gravity. The pivotal mounting H, J may be such as to allow considerable free movement (such as a small pin in a large hole). Riddling of the grate is achieved by causing the bars to rock upon their pivotal mountings which may be done by causing tripping members M to impinge against the lower portions of the bars. Should the tilting action be obstructed by a small foreign object the grate bar may rise within the confines of the pivotal fixing arrangement, thereby increasing the gap between individual bars and permit the foreign matter to be released. <IMAGE>

Title: Overload monitors
IPC: H02H3/00
Filed: 1980-04-17
Abstract: An overload monitor for electric- motor-driven machinery 10 measures (12-14) the power used during free running of the machinery to provide a datum power level. The datum power level is updated after each machine cycle, during a free running period, to allow for changes in oil viscosity, mechanical resistances etc. due temperature changes. During machine operation the monitor measures the power consumed above the datum level, and, if this exceeds a predetermined safe-power threshold, trips (19) the machine. <IMAGE>
