Patent GB-2093736-A (GB)
Title: Electro-fluidised bed recovery of metallic values
IPC: B01J8/42
Filed: 1982-02-09
Abstract: A method of recovering a metallic value from a metalliferous fume, i.e. gaseous effluent containing metalliferous particles, arising in smelting, refining and similar processes. The fume is drawn through a fluidised bed of particles (16) of metalliferous mineral or metallurgical flux, to which an electric field and a liquid binder are applied, to provide a product having a strongly adhesive outer layer of fume and a core of co-extractable mineral or flux, well suited to recovery by established extraction techniques. Two fluidised beds may be used in series in a method of partially segregating a fume of mixed metalliferous species, where one species has been generated by chemical reaction and nucleation in the gas phase, whereby the recovery of metallic values may be further facilitated. A pre-charging corona electrode (18) may be used. <IMAGE>

Title: Electromagnetic irradiation apparatus for destruction of tumours
Inventor: ENGLAND ERIC
IPC: A61N1/40
Filed: 1983-08-12
Abstract: For heating internal body organs or the interior of limbs by e-m radiation to kill malignant tissue, three 120 DEG -spaced radiators 2 are located in a tank 1 so distanced from one another as to produce a voltage standing wave pattern having a maximum within the trunk or limb 3 at the operating frequency. The radiator impedances and operating frequencies are adjusted so that the non-absorbed radiation received by each radiator from the other two is correct in phase and amplitude to substantially cancel the power otherwise reflected back from the third radiator to the RF source, thereby producing effective matching and preventing damage to the RF sources due to a high voltage. Either two or four (at the points of an equilateral tetrahedron) radiators may be used in similar arrangements. <IMAGE>

Title: Coin handling apparatus
Inventor: STEELE LEONARD MARMADUKE
IPC: G07D3/14
Filed: 1983-10-12
Abstract: A coin handling apparatus has a hopper to direct coins against the lower part of a rotating disc 8. Projections on the disc cooperate with an upstanding wall 9 surrounding the disc to define recesses that can each accommodate one coin. The coins in the recesses fall onto a ramp 12 adjacent the top of the disc and roll down the ramp sequentially. The coins are identified and passed to appropriate outlet passages. The coins may be identified by projecting an image of a coin onto an elongate photo-sensitive device, or by detecting the phase shift created in a signal passing through a coil when a coin passes the coil. <IMAGE>

Filed: 1984-01-11
Abstract: A projection optical system for projecting an enlarged image of an object including an optical fiber lens array and convex and concave lenses arranged in object and image spaces, respectively of the optical fiber lens array. The optical fiber lens array and convex and concave lenses are so arranged that a conjugated image of the object with respect to the convex lens and a conjugate image of the enlarged image with respect to the concave lens are formed at such positions that conditions of the optical fiber lens array necessary for projecting an erecting real image of unit magnification are satisfied. When the convex and concave lenses are arranged in the image and object spaces of the optical fiber lens array, a reduced image of the object is projected. An optical scanning apparatus is formed by arranging a plurality of projection optical systems side by side to form a long continuous scanning line. <IMAGE>

Title: Preventing drying out of printing ink upon stoppage of a printing machine
Inventor: LINDEN ALFRED
IPC: B41F13/42
Filed: 1984-01-17
Abstract: A method of preventing the drying out of ink upon stoppage of a printing machine involves a printing machine equipped for this purpose. The printing mechanism (29) is wholly or partly encapsulated e.g. by a hood (31) to provide an essentially gastight space which is filled with a protective gas e.g. through a duct (34) or with gasified solvent, the solvent being the same as that of the printing ink. After stoppage periods the encapsulation is removed, the protective gas or the solvent escapes, and the machine is ready for renewed printing without the machine having to be completely freed from printing ink at the start of the stoppage period. The part encapsulated at least includes the duct and fountain roller. <IMAGE>

Title: Control System Monitor
Inventor: CORBIN MALCOLM JOHN
IPC: G05B23/02
Filed: 1984-02-06
Abstract: In a control system monitor (10) signals (11, 12) are received from points in the controlled system (not shown). The signals are band limited by filters (14, 15) respectively to provide matched band limited signals (16, 17) for correlation by comparison logic (18) to provide failure flag output (19). The invention is based on the realisation that signals in different parts of the system should correlate if suitably conditioned, and that the result of the correlation is indicative of performance. The problems associated with prior art performance monitors and then difficulty of detecting common made errors may be overcome. <IMAGE>

Patent GB-2165116-A (GB)
Title: Optical receiver
Inventor: CHOWN DAVID PHILIP MARTIN
IPC: H04B10/43
Filed: 1984-09-29
Abstract: 57 In an optical receiver for the reception of a modulated light beam, the beam falls on a PIN diode (D1) connected to the input of an amplifier (-A) which has a feedback resistor (R1) across it. This resistor is shunted by the series combination of a Schottky diode (D2) and of a PIN diode (D3). The former diode ensures that a high magnitude pulse does not leave the receiver undesirably insensitive to a following smaller pulse. The latter diode, due to its low self-capacitance and low leakage, overcomes distortions due to the Schottky diode's higher self-capacitance and leakage. These effects are enhanced by providing. the series-connected diodes with a low value (e.g. 0.2 volts) of reverse bias, due to the different connections of the diodes (D2, D3) and the feedback resistor (R1) to a potential divider (R2, R3) between the amplifier output and a point at a reference potential.

Patent GB-2167029-A (GB)
Title: Article feeder
Inventor: TURNER WILLIAM JAMES
IPC: B65G31/04
Filed: 1985-11-01
Abstract: In order to feed a succession of objects by projecting them fairly accurately in a certain direction and at a certain speed, the feeder has a circulating conveyor belt 1 which is engaged by a roll 7 in such a way that the part of the belt immediately downstream of the roll 7 extends in the direction of feed (V). The roll 7 has a circumferential channel in which is located a resilient outer layer 10 which engages the successive objects 11. In this way, the layer 10 ensures that the objects 11 are travelling at a speed close to the circumferential speed of the roll 7 or belt 1, and the belt 1 locates the upper part of the object 11 as it leaves the nip. The objects 11 are fed between the belt 1 and roll 7 by means of a nozzle 12. Alternatively the belt may have the resilient layer. <IMAGE>

Title: Bar-code reader
Inventor: FELLOWES COLIN VICTOR
IPC: G06K7/10
Filed: 1985-11-19
Abstract: A bar-code reader for use in, for instance, retail outlets or libraries, is coupled to a data collection device by ultrasonic means. The reader is in the form of a wand (10) having a light emitter (16) and a light sensitive receiver (20) at one end and an ultrasonic transmitter (22) at the other end. Battery power is saved by operating the light emitter (16) in a pulsed mode during a quiescent state of a control circuit, and only switching to continuous operation when the white lead-in portion of a bar code is detected. Ultrasonic coupling of the wand (1) to the data collection device allows cordless operation, and, if required, several wands can be so coupled to the same device. <IMAGE>

Title: Cleaning of spraying apparatus
Inventor: ROBERTS GARY SKONE
IPC: B05B15/02
Filed: 1986-03-19
Abstract: For cleaning a spray gun 10 its air cap is removed and its spray outlet 16 is sealingly coupled to a conduit coupling 40. Cleaning solvent is then passed through the gun and coupling, and is collected in a reservoir 26 without being sprayed into the open air.
