Patent GB-2115365-A (GB)
Title: An apparatus for supplying flowable solid fuel
Inventor: LINK OTMARK
IPC: F02B19/14
Filed: 1983-01-24
Abstract: An apparatus for supplying stationary small- to medium-sized heating plant with flowable solid fuel such as coal dust or coal breeze has a vacuum conveyor running from a fuel storage container of the apparatus to the heating plant (1) for transporting the fuel from the container (2) to the boiler. The blower (7) of the conveyor has an aspiration port joined up with the container. The container has flexible walls of textile material and has an air blow- off line and a filter sheet for separating the coal dust from any coal dust-air mixture produced. This design makes it possible for the heating plant to be run automatically with the least leakage of dust and volatile substances out into the air. <IMAGE>

Title: Screw fasteners
Inventor: WILCOCK PETER DAVID
IPC: F16B23/00
Filed: 1983-06-13
Abstract: The head of the screw fastener has a conical depression 3 in it, which acts to guide a driving tool 5 into a driving recess 4 in the screw head as it is turned, even though the driving tool may not be presented accurately  to the screw head. Another feature is that the metal of the screw head is thickest where the applied torque is greatest. The driving recess may be a slot 4 as shown, or may be in the form of two crossed slots or a hexagonal recess. The screw may be of the headless (grub screw) type. <IMAGE>

Patent GB-2125686-A (GB)
Title: Separation of silage
Inventor: VAN DER LELY CORNELIS
IPC: A01F25/20
Filed: 1983-08-09
Abstract: A quantity of silage is separated from a bulk mass of the silage using a machine which has support means comprising a horizontal row of pointed tines (60) and upwardly extending blades (87, 88). The machine is reversed into the silage to cause the tines (60) and the blades (87, 88) to penetrate the silage. A severing member (53) comprising further blades is then lowered into the silage from above, to sever block of the silage which can then be carried away by the machine for use. The cutting action of all the blades may be enhanced by vibrating them. The severed block of silage may be displaced to rollers (22, 23) for chopping the silage up for discharge by means of conveyor (38). The machine can be given an additional function if the two top rods (49) are replaced by hydraulic rams. Operation of the rams enables the member (53) to be pivoted upwardly an rearwardly, and then on its return to roll a bale of crop formed in the field into the loading space between the sidewalls (17). <IMAGE>

Title: Stud welding apparatus with two wire control
Inventor: GLORIOSO PAUL A
IPC: B23K9/073
Filed: 1984-08-07
Abstract: The apparatus includes a tool 10 for welding studs by a drawn-arc technique and a control circuit 12 remote from the tool 10. Tool 10 includes a solenoid coil 38 and a core 36 movable thereby thus moving a stud 18 between a projecting and a withdrawn position in a spark shield 22. Welding current is applied to the stud via cable 32. The trigger 48 can close switch 58 thus completing a circuit from power source PS through wires 60 and 62, limiting resistor R1 and a blocking diode in wire 64 and wire 66. This causes a light-emitting diode OPTe in a sensing circuit SC to emit a burst of infrared light which is detected by photosensitive diode OPTd which initiates the welding sequence. Sensing circuit SC may be replaced by other low current requirement relaying circuits. The present apparatus requires only two wires to both initiate and control the weld cycle. <IMAGE>

Title: Cordless telephone system
Inventor: TATTERSALL PAUL RICHARD
IPC: H04M1/733
Filed: 1984-09-14
Abstract: A cordless telephone system includes a base station (15) connected to extension lines (L101 to L124) and a PABX (11) and a cordless handset (H101 to H124) corresponding to each exchange line. The base station includes ring detectors (119); a control unit (117), switches (121) and basesets (B101 to B108). In a system with 24 extension lines 24 handsets and eight basesets, the basesets transmit and receive signals over respective frequency channels, and three handsets share the channel of each baseset. With dynamic channel allocation, all of the handsets (H201 to H224) are adapted to be frequency agile and can communicate with any baseset (B201 to B208). Each baseset is allocated a different frequency channel. An idle marker tone generator (231) in the base station, under the supervision of a control unit (217), causes an idle tone to be transmitted from a free baseset. All free handsets tune to this tone; the first incoming or outgoing call seizes the free channel and the idle tone is transmitted over a new free channel. <IMAGE>

Title: Method and plant for reducing oxidic material
Inventor: SANTEN SVEN
IPC: C21B13/12
Filed: 1984-11-05
Abstract: The invention relates to a method and a plant for reducing oxidic material, while simultaneously generating a gas suitable for the recovery of thermal energy. A reduction gas (18) is produced containing mainly carbon monoxide and hydrogen from carbonaceous or hydrocarbon-containing material by means of thermal energy from at least one plasma generator (10) in a separate gas- generating shaft (11). The reduction gas thus produced, after optional sulphur separation (22) and after temperature adjustment, is conducted to a reduction shaft (1) containing the oxidic material. The partially spent reduction gas (4) withdrawn from the shaft is freed (5) from water and dust-like particles, after which a part-flow (6) of the return-gas is used for recovering thermal energy, while a part-flow is returned to the process (via 8). <IMAGE>

Title: A method of detecting sound impulses
Inventor: SANDOE IAIN DEREK
IPC: G01S5/22
Filed: 1985-10-05
Abstract: In a method of associating sound impulses derived from a common sound source, e.g. a gun or mortar, the sound impulses are detected by a plurality of spaced apart detector clusters (not shown) each of which comprises a plurality of sound detectors. The method includes the step of analysing data calculated from signals derived from the detector clusters, which data is indicative of the time of arrival and the angle of arrival of the sound impulses at the detector clusters, to associate those signals and thereby associate the related sound impulses which arise from the common sound source. The progressive 'filtering' action involves first monitoring a primary channel for an arrival, then choosing a secondary channel from the knowledge of the approximate angle of arrival in Channel 1 and searching for angles of arrival compatible with the known extent of the area of observation, thereby choosing a predicted time window for searching in Channel 2. A third channel is then examined using time and angle windows, and so on. <IMAGE>

Patent GB-2170373-A (GB)
Title: Image processing method
Inventor: MITA YOSHINOBU
IPC: H04N1/40
Filed: 1985-12-24
Abstract: In a digital copying or facsimile machine, where Moiré patterning is to be avoided, but characters and line drawings are to be reproduced with high definition, an edge detector 1, 2 controls S3, S4 the ratio with which a smoothed image singal S6 and an edge emphasized image signal S11 are mixed 305. Edge detection circuit 1 uses linear differentiation with a peak response frequency lower than that of a mesh image which is not to be treated as an edge containing image, whilst edge emphasizer 5 uses quadratic differentiation and has a higher peak response frequency than that of the edge detector 1. In an alternative either one of the edge emphasized image signal S11 or the smoothed image signal S6 are selected (Figure 27A). The edge emphasis circuit 302 may be omitted, the input image signal S1 then forming an input to multiplier 8 (Figure 33). <IMAGE>
