Patent GB-2249534-A (GB)
Title: Cleaning apparatus for endless conveyors.
Inventor: TUCKER ROBERT JAMES
IPC: B65G45/22
Filed: 1991-09-05
Abstract: Cleaning apparatus (1) includes a tubular device (2) which has a longitudinally extending slot (3) and input orifices (4 and 5) at opposite ends of the device. Screw threaded regions (6 and 7) of the tube (2) are arranged to allow respective hose connectors (8 and 9) of a supply hose (10) to be sealingly connected to respective ends of the device (2). The supply hose (10) has arms (11, 12) which emanate from a common source supply region (13) which, in turn, is connected in use to a fluid supply means (14). The fluid supply means (14) is preferably arranged to supply high pressure air to the device. The apparatus (1) is fixed adjacent to a load carrying surface of a conveyor with the slot (3) being disposed such that air flowing out thereof is directed at the load carrying surface. In use, the supply means is caused to supply air at high pressure through each arm of the supply hose (10) and, in turn, air flows through the input orifices (4, 5). Subsequently air flows out of the output orifice towards the load carrying surface of the conveyor and debris is removed thereby.

Title: Recirculating automatic document feeder
Inventor: SAEKI SHIRO
IPC: B65H85/00
Filed: 1991-10-03
Abstract: Documents to be recirculated past a platen 3, e.g. of a copier, are sequentially separated at 18, 19 from the bottom of a pile P, passed over the platen and then returned to the top of the pile for the next circulation, which is arranged to begin before the last document has returned to the top of the pile, thereby saving time. A gate 13 is initially lifted from the position shown and the pile is shifted to the left to enable separation and feeding of the documents. The gate then descends onto the shifted pile to catch returning circulated documents. When the feeding of the last document from the shifted pile is sensed, the gate is again lifted to start the next circulation. The last document or two from the first circulation is/are subsequently added to the top of the pile. The documents may be inverted at 42. <IMAGE>

Patent GB-2269252-A (GB)
Title: Telecommand of moving vehicles on rails
Inventor: WILLIAMS PHILIP ELPHEE
IPC: B61L3/22
Filed: 1992-07-30
Abstract: Powered lifts and Stairlifts and vehicles which do not have trailing cables may need to be remotely controlled by a Telecommand signal. This signal is conveyed to the moving vehicle by the use of Induction loop or radio technology and the rail on which the car runs is part of the loop or antenna. The command signals are picked up by a suitable receiver on the moving car and used to control its movement.   The use of the rail as a transmission line enables the receiver pick-up coil to be fixed at a consistent distance from the rail and provide the receiver with a reliable signal whether the rail is straight or curved. A separate wire inside or alongside the rail may be used instead. <IMAGE>

Title: Synthetic refuse container with identification means; reading code stored therein
Inventor: VAN DE WEYNGAERDT MARC
IPC: B65F1/14
Filed: 1992-08-25
Abstract: The synthetic refuse container is provided with an identification means for storing an identification code, which identification means is formed by a series of metal strips (4) which are embedded in a synthetic material in or on a projecting edge (5) of the container. The identification code is then determined by the number and mutual position of the strips, in particular the presence or absence of a metal strip (4) on a number of predetermined positions. Apparatus for reading this identification code detects by means of magnetic fields whether there is a metal strip (4) on these predetermined positions or not. The code can thus be read automatically enabling automatic registration of the refuse. <IMAGE>

Title: Electromagnetically operable double-seat valve
Inventor: BREHM WERNER
IPC: F16H61/02
Filed: 1992-10-27
Abstract: An electromagnetically operable double-seat valve has an electromagnet (13) which interacts with an armature (15) which is connected to a plunger (17). The latter acts on a longitudinally cylindrical valve member (12) which is constructed as a hollow body and, on its end facing away from the electromagnet, has a collar (32) which points radially outwards and interacts with two valve seats (33, 35) which are of flat construction. The one valve seat (33) is constructed on the valve housing around the slide hole (11) which accommodates the valve member (12), and the other valve seat (35) is constructed in a plate (31) which is arranged at the end of the housing hole (11). A compression spring (30) which acts on the valve member is also supported on the plate (31). In the illustrated, rest position, port (37) is connected to port (42) via a passageway (46) in the valve member (12). Energisation of the electromagnet (13) moves the valve member against the valve seat (35) and connects port (37) with a port (38, 39). <IMAGE>

Title: Optical filter
Inventor: COUPER JOHN HOWARD
IPC: H04B10/40
Filed: 1993-03-01
Abstract: An optical system is provided, comprising first and second waveguides 1, 2 constituting a transmission path for optical signals. Interposed in a gap 3 between the ends of the two fibres is an insert 4 which extends halfway down the gap. A wavefront of wavelength  lambda propagating between the waveguides encounters the insert and shears, and the portion passing through the insert is retarded with respect to the remainder. Depending on wavelength  lambda , the two portions may constructively or destructively interfere. For two propagating wavefronts at  lambda 1 and  lambda 2, one may be coupled into waveguide 2 whilst the other may be coupled out of the transmission path. An effective filter is thus provided. An application in a passive optical network is described. The insert may alternatively consist of a slot cut halfway into a single fibre. <IMAGE>

Title: Matrix type display
Inventor: IMAMURA YOHICHI
IPC: G09G5/00
Filed: 1994-11-10
Abstract: A matrix type display device simplifies the process in a display signal generating circuit 74 while relieving the load on an external CPU, and arranges freely character and icon display areas while preventing the quality of display from being degraded by the shadow phenomenon and others. A display code memory 30 stores character display codes and icon display codes for one image at a desired address arrangement. A pattern generating circuit 28 transfers image patterns for the display codes to a display signal transferring circuit 76 through a multiplexer 27. A decoder selecting device is responsive to a decoder select signal to select a decoder, thereby controlling voluntarily the timing of latch signal generation, Display signal input in the time division manner is latched in first and second latch circuits through the latch signal. Thereafter, the display signal is transferred to a signal electrode driving circuit 78 through a line memory to display an image on a matrix panel 82. The shadow phenomenon is reduced by displaying the icons at positions chosen in accordance with proportions of dots lit. <IMAGE>

Title: Railway signalling data checking system
Inventor: ROWBOTHAM ANTHONY JOHN RIGBY
IPC: B61L19/06
Filed: 1994-11-17
Abstract: In a microprocessor based interlocking system the various elements of the signalling system, signals, points and track circuits are identified by number or letter codes eg 3 or 4 digits or letters. These ID codes are stored in the system and compiled for processing in a control program which is extremely complex and may contain thousands of occurrences of the equipment ID codes. "Dyslexic" entry of a code initially will escape a check against a fist of valid codes if the false entry coincides with another valid code. In this invention valid codes are limited to those (for example) which have successive digits never decreasing, ie each digit equal to or greater than the preceding digit. In numerical codes the error can be detected from the code itself by merely comparing each digit with its predecessor. Dyslexic transcription will then produce a code infringing the rule and thus clearly invalid. <IMAGE>
