Patent GB-2241900-A (GB)
Title: Board game
Inventor: PEARLMAN STEVEN
IPC: A63F11/00
Filed: 1990-03-17
Abstract: A board game comprises a hexagonal board and a plurality of small hexagonal spaces disposed on the board. Selected spaces carry a letter of the alphabet. Means of random selection are arranged to determine     (i) a letter of the alphabet:   (ii) a subject category: and optionally (iii) the length of a word, position of a letter in a word or the frequency of occurrence of a letter in a word.   From the information given by the random selection means (roulette wheel, dial and pointer, cards, dice or electronic device) each player in turn attempts to identify a word in the time allowed by a timer. <IMAGE>
Patent GB-2233086-A (GB)
Title: Optical displacement encoder
Inventor: DONOVAN PAUL M
IPC: G06F3/038
Filed: 1990-05-14
Abstract: To minimise power consumption in optical encoding, a light source (D1, D2) is pulsed and a detector (PT1, PT2) is activated in synchronism with the light source. Light interrupting means such as a slotted encoder disc (18) opens and closes the optical path from the light source to the detector resulting in a pulsed electrical output signal for use in encoding. A pair of encoders responding respectively to movement in X and Y directions may be used in a mouse for cursor control of a computer display system, the two light sources being pulsed alternatively to minimise peak power consumption. <IMAGE>

Patent GB-2236393-A (GB)
Title: Seismic migration using a multiprocessor computer
Inventor: MOORHEAD WILLIAM DEAN
IPC: G01V1/36
Filed: 1990-09-24
Abstract: In a preferred embodiment of the present invention, methods are provided for Kirchhoff-migrating seismic data using a parallel computer. The methods of the present invention preferably use a multiprocessor machine that is interconnected to form a hypercube. The presently preferred method is to build up one or more migrated output traces in each processor (node) designated as a "migration" processor mig 1-M, as input traces are passed from migration node to migration node along a nearest-neighbor chain. When an output trace is completed, it is sent by a migration node to storage via an appropriate I/O processor and the migration node begins building a new output trace. There is essentially no limit to the length of seismic line which can be so migrated. Alternatively, the input traces may be held in the migration nodes and the output traces passed from node to node along a nearest-neighbor chain, or the input and output traces may be passed in opposite directions along the chain. Further, the use of multiple migration chains allows for efficient operation over a wide range of number of available processors. <IMAGE>

Title: Method/apparatus for disposing of filter cartridges.
Inventor: WOLF JOACHIM
IPC: B09B3/00
Filed: 1991-06-07
Abstract: The method involves condensing solvent residues from e.g. varnishes, paints, adhesives coating masses etc in a condensate collecting tank 38. The filter cartridges, together with solvent residues are ground in a sealable container 11 with heating of said cartridges together with the solvent residues; gaseous solvent is drawn from the sealable vessel into a solvent condenser 33 by a negative pressure pump 43 connected to the solvent condenser; and condensate that has precipitated in the solvent condenser 33 is fed to condensate collecting tank 38. As shown, container 11 has a lid 13, a shaft 21 bearing blades 23, 24, and a shell 26 feeds in heat. Control and regulating apparatus 48 controls an electric motor 16, and heat input. Attached to lid 13 is a nozzle 29 which merges into a solids separator 31 from which a negative pressure-resistant pipe 32 passes to condenser 33. Inlet 49 serves to introduce inert gas e.g. nitrogen. <IMAGE>

Title: Locks with inductive code transmission
Inventor: NIEUWKOOP EVERT
IPC: G07C9/00
Filed: 1991-12-18
Abstract: An electronic lock is constructed to resemble the appearance and functionality of a conventional cylinder lock. Its key (22) has a bit (24) in which is mounted an integrated circuit chip (27) storing the key code and including a transmission coil for inductive coupling with reading means of the lock. The latter includes a coil (33) for generating a high frequency alternating magnetic field across a localised region of the keyway (12) concentrated via a toroidal ferrite core structure which defines a gap spanning the keyway through which the chip (27) passes when the key bit (24) is inserted. This core structure includes a U-shaped part (31) in the stationary lock housing (30) around which the coil (33) is wound, and two parts (35) mounted in the barrel, one to either side of the keyway (12), which register with the part (31) in the housing when the barrel is in the key-reading position. Further ferrite pads (28) may be mounted to either side of the coil in the key itself, to register with the ferrite parts (35) in the barrel. By this means, optimum flux coupling between the lock and key may be achieved, thereby minimising power consumption. <IMAGE>   <IMAGE>

Title: Reciprocating cutter blades of power driven tools
Inventor: HAYDAY GEOFFREY DENIS
IPC: B23D49/00
Filed: 1993-07-21
Abstract: A cutter arm of a power tool comprises two reciprocatable cutter blades A, B having cooperating teeth which are not uniformly aligned allowing the cutting load to be distributed over the cutting cycle. A spacer tooth d on one of the blades ensures that groups of teeth 1, 2 are simultaneously at different parts of the cutting cycle thus evening out the cutting load. Consecutive teeth may be offset by increasing amounts along the length of the cutter arm (figs 4 - 6). The power source to drive the cutters may be an electric motor, compressed gases or an internal combustion engine. This cutter arrangement may be utilised on hedge trimmers, agricultural combine harvesters, river weed cutters, grass cutters, power carving knives, power saws and hair or wool clippers. <IMAGE>
Patent GB-2282721-A (GB)
Title: Latching three-state output driver
Inventor: HOWARD DAVID WILLIAM
IPC: G06F3/00
Filed: 1993-09-30
Abstract: A functional block, such as a random access memory, provides a data signal to one input 12 of a multiplexer 26 and then via a three-state buffer stage 24 to an output signal line 6. The other input of the multiplexer 26 receives a recirculated value from the output signal line 6. In operation, the buffer stage 24 is enabled as soon as the functional block 10 is enabled. A data valid signal indicating when the data signal from the functional block is ready for output switches the multiplexer 26 from selecting the recirculated value to selecting the data signal value. The signal on the output signal line 6 always has a defined state derived from either the existing output signal level or, when it becomes available, the new data signal. Power wastage through the driving of spurious signals on the output signal line 6 is thus avoided. <IMAGE>

To avoid cavitation damage in the region of the sealing surfaces, a throttle is disposed downstream of the sealing edge (17). The throttle may be provided by an annular groove (62) in one of the conical surfaces (13, 15). <IMAGE>
