Patent GB-2059705-A (GB)
Title: Electronic noise suppression
IPC: H04N5/217
Filed: 1979-10-02
Abstract: Charge-coupled devices (c.c.d.) delay lines, when used as temporary stores of information in electrical form, exhibit a tendency to distort the stored information. Each signal is affected similarly so the distortion is called fixed pattern noise. The invention overcomes this problem by a circuit arrangement which apparently eliminates the distortion. Alternate signals of a succession of signals are inverted by a variable-sign amplifier (2) before storage in a c.c.d. delay line (6) and re-inverted in a second variable- sign amplifier (9) after removal from the store (6); the result is to reverse the distortion on sequential signals and thus significantly reduce the effect of the distortion on any consecutive pair of signals. The main use of the invention is in infra- red imaging apparatus, providing a visible display of a scene viewed by infra-red detectors. (Fig. 1). <IMAGE>

Filed: 1979-12-20
Abstract: The apparatus comprises a set 10 of disposable casting moulds for casting cured plastics lenses, which comprises a strip 12 comprising debossed mould recesses (16) having the dimensions and contours required for the desired lenses. The strip is formed of a material which maintains its dimensional stability at the curing temperature of the cast plastics material 22 used to make the lenses and has sufficient strength that the strip can serve as a workpiece holder during subsequent machining and/or polishing of the cured plastics lens. The plastics material is cast and cured in the mould recesses, the latter being covered by a separate cover sheet 14 having depressions (20) fitting snugly in recesses (16). The plastics material may be cured by immersion of the filled and covered mould recesses in a bath of water 24 maintained at curing temperature.

Title: Arrangement for distribution of television games and the like
IPC: A63F13/12
Filed: 1980-01-25
Abstract: An ensemble of video game controlling programs are multiplexed (e.g., on a time division, word-interleaved basis) and distributed over a common communications link 11, e.g., a CATV cable. Each authorized TV user thereto connected has an adapter with a read/ write (RAM) memory 59. A particular game specified on an input device, e.g. a keyboard 42, selects the words of the game program listing for reception and loading into the RAM. Once loaded, the RAM causes the microprocessor controlled unit 30 to execute the selected game with operator participation in a per se conventional fashion, communicating with the TV receiver 67 via a modulator 44 feeding the aerial socket. For a new game the input device is changed to replace the adapter RAM contents with the instruction set for the new game. <IMAGE>

Title: Liquid fuel injection pumping apparatus
IPC: F02M41/14
Filed: 1981-10-21
Abstract: A liquid fuel injection pumping apparatus of the rotary distributor type has stop means defined by complementary inclined surfaces on a rotary portion 14a, coupled to a drive shaft and on the cam followers 44, 45 associated with the pumping plungers. The cam followers and the distributor member 28 are axially movable to vary fuel quantity. In order to vary the initial rate of fuel delivery one or a reduced number of plungers only is arranged to deliver the initial flow of fuel. This is achieved by axial adjustment of one or more cam followers 44a, 45a relative to the distributor member so that the associated plunger or plungers can move outwardly further during the filling stroke of the apparatus and will therefore be moved inwardly before the remaining plungers. Alternatively an axially movable part may be provided on said rotary portion. <IMAGE>

Title: Pivot joints for window stays
IPC: E05D11/08
Filed: 1982-01-13
Abstract: The invention concerns friction joints for foldable window stays including a mounting plate 5 and an arm 4 which are pivotally connected by a rivetted joint. The joint includes a rivet 1 having a head 7 received in a counterbored low friction bushing 2 which is non-rotatably seated in a recess 9 in the arm 4. The rivet shank 6 extends through aligned holes 10, 12 in the arm 4 and plate 5 between which a spacer 3 is interposed. The tail of the rivet is clinched on the underside of the plate 5 to locate the rivet against rotation relative to the plate 5 and by such clinching, frictional restraint is achieved in the joint. High loads on pivotal movement of the joint in use of a window stay are transmitted between the co-operating bearing surfaces of the bushing 2 and the rivet head and shank. An exemplary embodiment of a stay is also described. <IMAGE>

Title: Applying granules to tiles
Inventor: AMARAL JORGE MANUEL DE MIRA
IPC: B05C19/04
Filed: 1982-04-05
Abstract: Roofing tiles are partially granulated by passage in succession beneath a chute (7) which discharges granules onto a triangular deflector (8). The deflector (8) is pivotable about a horizontal axis between two positions so as to deflect granules in two directions. The position of the deflector (8) is controlled as a function of tile position. The deflector operates in one position to provide the leading edge (14) of a tile with granules (Figs. 3 and 4) and then in the other position to provide the top surface (15) with granules (Figs. 5 and 6). Granulation of the surface (15) continues up to cut-off point (16) to leave the remainder ungranulated, the deflector then pivoting (Fig. 7) back to its initial position. <IMAGE>
