Title: Stop motions in tubular stranding machines
Inventor: GNENSCH EUGEN
IPC: D07B7/02
Filed: 1986-08-04
Abstract: The machine has a stranding tube (22, Fig. 2) rotating about a rockable bobbin cradle (23) to which a shutter (25) is attached. Two elements (24) rotate with the tube to produce signals in a stationary generator (11). Holes (20) in walls rotating with the tube (22) allow passage of a light beam as they rotate to produce a signal in a receiver (1, Fig. 1). A counter (8) counts a signal from the receiver (1) and is reset by a following signal from the generator (11). A counter (9) counts a signal from the generator (11) and is reset by following signal from the receiver (1). If the receiver or generator fail, or the light beam is interrupted by the shutter (25) rocking with undesired cradle rocking, then a counter memory fills and triggers a stop command in a flip-flop (17) via a NOR element (16). A clock generator (3) is used so that the machine is stopped if no signal is transmitted by the receiver (1) within a preset time. The preset time is lengthened during machine acceleration. <IMAGE>

Title: Electrochemical filter conditioning
Inventor: BOWEN WILLIAM RICHARD
IPC: B01D35/06
Filed: 1987-03-07
Abstract: A porous, electrically conducting filtration membrane 2 is conditioned by setting up an electrochemical cell comprising a first electrode constituted by the filter, a second electrode 5, and an electrolyte. Application of a potential across the cell results in restructuring or realignment of the layers formed on the filter during filtration. This realignment or restructuring is such as to prevent or substantially diminish the further fouling of the filter or membrane. The overall rate of filtration is therefore greatly improved. The electrolyte is normally the process feed. <IMAGE>

Title: Manufacture of switch pad arrays
Inventor: BRIGGS JAMES
IPC: H01H13/702
Filed: 1988-08-05
Abstract: A method of producing an array of switch pads, for use in push-button switches for a keyboard, comprises the formation by a moulding technique of a sheet of rubber or flexible synthetic material including a plurality of spaced apart and hollow cup-shaped protuberances 14 of a desired configuration. After moulding, each protuberance 14 is separated from each immediately adjacent one by parting the sheet between the protuberances 14. A panel of plastics or other sheet material 26 is produced having apertures 28 therein in a pattern corresponding to the keyboard in which the switches are intended for use. The separate protuberances 14 are individually inserted in the panel 26, each as a close fit in a respective one of the apertures 28. In the resultant switch pad array the protuberances 14 project at one side of the panel 26 and each of them may have an electrically conductive portion included therewithin. <IMAGE>

Patent GB-2240357-A (GB)
Title: Single action security catch
Inventor: MILLER HAMISH
IPC: E05C17/16
Filed: 1989-11-17
Abstract: A 'single action security catch' which can be fitted to any door and which comprises a sliding bolt 10 and a hinged slotted link 11. The sliding bolt 10 is fitted to the door and the slotted link 11 is fitted to the door frame. The slotted link 11 can swivel on a pivot pin 20 secured in an anchor bracket 16 which is secured fixedly to the door frame. The slotted link 11 can only move in a vertical plane and when impelled upwards (or downwards if fitted to a left hand door) it will cause the door to open because the sliding bolt 10 must follow the slot 15 in the slotted link 11. The door can only open to the extent of the length of the slot 15 unless the sliding bolt 10 is manually moved horizontally away and out of the slotted link 11. <IMAGE>

Title: Forming ohmic electrodes on diamond
Inventor: NISHIMURA KOUZO
IPC: H01L21/324
Filed: 1992-01-08
Abstract: A process for forming ohmic electrodes on a doped or undoped diamond film 2, comprises the steps of implanting ions of at least one element selected from the group consisting of B, Li, Na, Ar, C, Ti, W, Ta, Mo, Fe, Ni and Co in the diamond film at the surface areas to be formed with electrodes, forming electrodes OC on the ion implanted areas, and heating the diamond film formed with the electrodes at a temperature of 400 DEG C or more. With this process, charger carriers can be moved between electrodes and the diamond film to thereby obtain ohmic electrode-diamond film contacts, and also the surface recombination speed of the charge carriers is increased for reducing the contact resistance between the electrodes and the diamond film. In addition, by heating, the contact resistance is furthermore reduced. <IMAGE>

Title: Kerb negotiator
Inventor: VINCENT FREDERICK REGINALD
IPC: B62B5/02
Filed: 1992-01-13
Abstract: A kerb negotiator is a device which may be fixed to a wheelchair in order to help the pusher of the wheelchair raise the wheelchair up a kerb or similar obstacle, and consists preferably of two wheel arms 1 on which are mounted one or more sets of wheels 2. The whole assembly is secured to the wheelchair by means of mounting plates 5 which allow it to be pivoted by stepping on the foot bar 4.

Title: Motor control circuit for an electrically powered tool
Inventor: HONMA SHIGERU
IPC: H02P29/40
Filed: 1992-03-26
Abstract: A control circuit for use in an electrically powered tool, such as a screw driver or drill, includes a double-pole double-throw (DPDT) relay switch 3 having two wiper contacts movable between ON and OFF positions. A motor 4 is connected to a power supply 1 through the DPDT relay switch 3. To stop the rotations of the motor 4, the two wiper contacts trip from ON positions to OFF positions in ganged fashion. With the use of DPDT relay switch 3, even if one of the two wiper contacts undergoes a chattering action in its OFF position, the remaining wiper contact allows a large braking current to flow in a closed loop, whereby contacts of the DPDT relay switch 3 are prevented from being melted as a result of the braking current. <IMAGE>

IPC: H04L27/20
Filed: 1993-03-01
Abstract: In the modulation and demodulation of a plurality of frequency separated channels on a radio frequency carrier by digitally coded speech or data, the speech or data 3 is modulated on a digitally, generated sub-carrier by minimum shift keying 5 (or FSK) and after conversion to analogue form 11 the modulated sub-carrier is mixed 15 with an RF carrier 18 of fixed frequency to produce the signal for transmission 17. Reception and demodulation of the transmitted signal 31 are effected by the reverse processes. Frequency multiplication is effected after the digital to analogue conversion 11 by producing analogue samples of very short duration 12 and applying them to a suitable filter 13. Frequency division during the analogue to digital conversion 39 is effected by sub-sampling. Application is to CT2 cordless telephones, GSM, DECT, PCN, PHP, cellular radio telephones or paging systems. <IMAGE>
