Title: Circuit arrangement for selecting a radio signal from a number of signals
IPC: H04N5/45
Filed: 1979-06-21
Abstract: A channel selecting circuit for a radio or television receiver has a controllable oscillator, the frequency of which is determined by a control loop depending on a binary number N supplied by a microprocessor (11) on the basis of code input data. The control loop has frequency dividing means (3, 4) providing a first signal from the oscillator depending on the number N, and a comparator (5) for comparing the first signal with a second frequency reference signal to provide a third signal for tuning. A memory (12) has cells for digital storage of data relevant to the signals being tuned. The number N can be supplied both in direct response to the coded input data or by calling up data from the memory (12). The overall situation of the memory (12) can be displayed to keep the user informed as to which signals have been memorised and which memory cells are available. A circuit is provided for checking the validity of data in the memory. <IMAGE>

Patent GB-2064355-A (GB)
Title: Fluidised bed combustor
IPC: F23C10/00
Filed: 1979-10-26
Abstract: A method of operating a fluidised bed combustor 1 comprises the steps of passing a pressurised oxygen- containing gas, for example air, through two vertically aligned beds 7 and 8 containing fuel material to promote fluidisation of the beds 7 and 8 and combustion of the fuel in the beds. The air also maintains the beds at a pre-determined temperature. The beds 7 and 8 are operated without a free-board between each bed. It is thus possible to achieve a rapid turn- down by slumping the lower bed by stopping the air supply thereto. A conventional fuel may be fired on one bed to help, with the aid of the deep beds which retain heat, the complete combustion of, for example, a particularly difficult waste fuel which is to be fired on the other bed. Heat and waste fuel can be transferred from one bed to the other bed. <IMAGE>
Patent GB-2037114-A (GB)
Title: A turn-off accelerating circuit for use with a power transistor
IPC: H03K17/042
Filed: 1979-11-26
Abstract: A darlington-connected power transistor pair, (T3,T4) switches current flowing through a load (13) and a flywheel circuit (C3, 24, 16). The current is drawn from mains (11) via a rectifying bridge (12) or from a standby battery (10), and the voltage applied to the load (13) is regulated by a circuit (23) which modulates the duty ratio of a rectangular wave applied to the base of the power transistor (T3, T4). Two techniques for assisting transistor turn-off are combined. During turn-off, a quench circuit comprising a first capacitor (1) and a diode (D1) shunts current around the power transistor until it is fully turned off. The first capacitor (C1) discharges during the next on period via the power transistor and a resistor (R1) to prepare the capacitor for the subsequent turn off. Part of the voltage then appearing across the resistor (R1) is used to charge a second capacitor (C2) via a second diode (D4) to provide a source of turn-off bias potential (point A) lying outside the range of potentials provided by the battery or the diode bridge. The quench circuit thus also acts as the primary source for the turn-off bias potential. The availability of such a source reduces the turn-off time of the power transistor and thereby reduces the capacitance required of the quench circuit. <IMAGE>

Title: Apparatus for the storage of sheets of paper
IPC: A61B17/00
Filed: 1979-12-04
Abstract: Apparatus for the storage of sheets of paper comprises an inclined transport track comprising two plates (12, 13) leading down to a store. The sheets of paper (B) enter between the two plates (12, 13) and are driven therebetween the store. A tubular chamber (25) is arranged laterally at the end of the lower plate (13), which chamber (25) is connected to a source of compressed air and is provided with orifices which direct the air at angles towards the bottom of the store which has a step by step movable bottom wall (32). Means (40, 47) for driving the sheets of paper into the store are provided, and, in use, jets of air prevent the front edge of each sheet of paper from rolling up as it enters the store and subsequently forms an air cushion for the entering sheet of paper to attach the sheet to the means for driving it into the store. A feeler (52) controls the step by step descent of the bottom wall (32) of the store as the sheets enter the store. <IMAGE>

Patent GB-2046525-A (GB)
Title: Manually operable electric switch
IPC: H01H9/02
Filed: 1980-03-04
Abstract: A manually operable electric switch 1 includes a control lever 2 pivoted at 3 to control the movement of a longitudinally slidable rod 11 which closes a microswitch 19 when the applied force is within a predetermined range and opens the switch 19 when the force is below or above this range. The initial movement of the rod 11 is controlled solely by a spring 13, but when an enlargement 12 on the rod 11 moves into contact with a ring 14, it moves it away from a shoulder 21 and further movement is controlled by the combined effect of the spring 13 and a spring 15 acting on the ring 14. Engagement of the enlargement 12 with the ring 14 coincides with entry of a roller 16 or an actuating arm 17 of the microswitch 19 into a recess 22 in the rod 11 to operate the micro-switch 19 and the contacts of the switch are therefore opened for an applied force either less than or greater than that required to bring the enlargement 12 into engagement with the ring 14. <IMAGE>

Title: Improvements relating to imaging devices
Inventor: IAN MACDONALD GREEN
IPC: G01S15/89
Filed: 1980-06-18
Abstract: An ultrasonic imaging system for generating a visual representation of objects in a field of view and also a visual representation of the range objects within a selected region of the field of view. The system has an acoustic wave generator (5) which insonifies the field of view with a continuous wave (CW) of acoustic radiation, reflections from the field of view being detected by an image converter tube (4) which is scanned, in raster fashion, to generate electrical signals which are then utilised to generate a visual display (11). A switch (12) is actuated intermittently to interrupt transmission of the CW acoustic radiation for a preset time interval and a pulse, of relatively short duration, is transmitted during that interval. As the pulse is transmitted the image converter tube (4) is scanned repetitively along a single, selected line corresponding to the selected region of the field of view, the electrical signals generated from each such scan being displayed successively (at 13), and being indicative of progressively greater ranges. <IMAGE>

Title: A permanent record medium
IPC: B41M5/124
Filed: 1980-07-03
Abstract: The medium comprises a plurality of layers of laminar material (15, 16, 17, 18, 19) including two outer layers (15, 16) of tear-resistant, transparent, impermeable material and at least one inner layer (19) sandwiched between the two outer layers, this inner layer being made from a material on which optically distinguishable marks appear when the record medium is subjected to localised pressure above a certain threshold value. This effect is obtainable by including with the inner layer (15) a material (14) incorporating micro-encapsulated inks which permeate the material upon rupture under pressure of the micro-encapsulation. A method of manufacturing identity cards and other such documents employing the permanent record medium is also disclosed.

Title: Drill stand work table feed
IPC: B23Q5/34
Filed: 1980-07-17
Abstract: An elevator for a drill stand table (16) comprises a sprocket chain (24) suspended at the top of the drill column (14) to extend vertically downwardly along the column, and a companion sprocket wheel (36) mounted on the table for rotation about a substantially horizontal axis. A friction brake mechanism (54, 56) restrains angular movement of the sprocket wheel and holds the table in the vertical position thereby determined. A crank (62) connected to the sprocket wheel (36) rotates the sprocket wheel up or down the chain (24) correspondingly to position the table (16). Optionally, a ratchet mechanism (70, 74) allows the crank to override the brake in the up direction of the sprocket to relieve required effort. Angular chain positioning is allowed by a bearing (32) supporting the chain bracket (34) running in a groove (30) in a column collar (28). <IMAGE>
