Title: Call Routing in a Wireless Telecommunications System
Inventor: COOPER GUY ALEXANDER
IPC: H04Q11/04
Filed: 1996-10-09
Abstract: The present invention provides a central terminal, and method of operation of such a central terminal, for routing calls between a telephone exchange connectable to the central terminal and a plurality of subscriber terminals, the central terminal being arranged to communicate with the subscriber terminals via wireless links, and each subscriber terminal being arranged to support one or more lines to subscriber telecommunications equipment. According to the invention, the central terminal comprises a storage arranged to store a phone number list associating phone numbers for said subscriber telecommunications equipment with corresponding of said lines to subscriber telecommunications equipment. The present invention provides the central terminal with far more flexibility in the way it manages calls, since the central terminal is no longer restricted to performing fixed mapping. By providing a phone number list within the central terminal, associating phone numbers for said subscriber telecommunications equipment with particular lines, the central terminal is provided with more knowledge about the subscriber terminals and telecommunications equipment that it supports. The central terminal can use this phone number list to handle calls without utilising fixed timeslot mapping. Hence, assuming the exchange has the ability to include within a call directed to the central terminal information identifying the phone number to which the call is directed, the central terminal will be able to use the phone number list to determine which line should be use for transmitting the call.

Title: Fish pole retrieval system
Inventor: BAKER ROBERT GLYN
IPC: A01K97/24
Filed: 1997-10-01
Abstract: The retriever consists of a round or egg shaped flat piece of sinkable material with a section removed the same shape. A V cut is made on the inside of the rim. A slit no thicker than a 15lbs fishing line is made from the apex of the V cut towards the rim. A stainless steel blade is fitted across the slit. Directly opposite the V cut is placed a hole with a ring through it. Attached to the ring is a length of cord. An angler whose hook is snagged slides the retriever down his pole. It drops off the end, over the float and sinks down to the hook. By pulling the cord the line near the hook will slide around the inside of the retriever, enter the V cut and then the slit and be cut by the blade.

Title: Video camera recorder which records via a buffer store so that video data generated before the recorder is switched on is recorded
Inventor: DICKINSON LEO
IPC: H04N5/781
Filed: 1997-12-05
Abstract: A video camera recorder is provided with "hind-sight" by locating a buffer store between the camera pick-up (eg a CCD) and the recording device. The buffer comprises a RAM configured to operate as a FIFO buffer and is interposed between the input and the recording sections of a camcorder. The action of the buffer is to delay (eg for 10 seconds) the recording of the audio and video data to the recording medium for a period of time at least equal to the period between the operator triggering the recording control and the data being registered on to the recording medium. Prior to recording the buffer merely overflows. The arrangement may be used for time lase and slow motion video effects by using the buffer as a time shifter. The recorder may be used for surveillance enabling images before an event to be recorded, for car security and as an electronic still camera. Single frames or multiple frames may be stored for later retrieval on to the main recording medium. The data may be monitored as it flows through the buffer.

Abstract: 978, 516. Colour photographic developing processes. AGFA A.G. March 22,1962 [March 27, 1961], No. 11046/62. Heading G2C. In a colour photographic process the black and white development is effected in two stages, the first in a developer free from bromide ions and the second in one including bromide ions. The first developer advantageously has a pH value lower than 7, the second includes alkali and its use is followed by normal re-exposure and colour developing procedure. Improvements 'm coloured reproduction with levelling of gradation and reduction of fog are attained, especially with paper supports. An example describes a three-layer material using B.I.O.S. couplers and a baryter coated paper support, together with normal and neutral black and white developers and a colour developer for comparison purposes after stepwedge exposure of the material.

Title: Torque converter and lock-up clutch arrangement
Inventor: FISCHER ROBERT
IPC: B60W30/18
Filed: 1995-02-21
Abstract: A torque transfer system for the drive train of a motor vehicle equipped with a gear-change gearbox. The system includes a torque converter 11 which is in driving connection with a drive assembly of the vehicle and is in active connection through an output shaft with an automatic gearbox connected on the output side. A friction clutch 12 is mounted parallel to the hydrodynamic converter and will be operated by the pressurised flow medium. The clutch has a pressure chamber 24 between a turbine wheel of the converter and a ring piston connected to a friction disc on one side, and another pressure chamber 25 between the ring piston and a converter cover on the other side. The pressure chambers are designed so that a differential pressure existing between them determines the torque transferable by the friction clutch. The system also has a measured value detection system, a central computer unit and a hydraulic system which in conjunction with the computer unit produces a change in the differential pressure between the two pressure chambers and thus in the torque transferable by the friction clutch. The clutch is controlled in all driving gears and the torque converter has a torque conversion > 2.5.

Title: Method of processing seismic data
Inventor: DE HOOP MAARTEN VALENTIJN
IPC: G01V1/28
Filed: 1995-06-09
Abstract: A method is provided for processing seismic data samples obtained from seismic signals propagating in an anisotropic medium. The data samples are associated with scattering angles and azimuth at each migration dip at each image point of the medium. An inverse operator is then applied to the samples so as to provide intermediate anisotropic elastic parameter combinations for each migration dip at each point of the medium. The inverse operator comprises an inverse of a scattering function for variations in elastic parameters from a reference medium against scattering angle and migration dip. The intermediate anisotropic elastic parameter combinations are then migrated to their proper locations, using an inverse Generalised Radon Transform having defined Jacobians.

Title: Loading mechanism for an inkjet cartridge with a recess in a lower surface thereof
Inventor: MIYAZAWA HISASHI
IPC: B41J2/175
Filed: 1997-07-04
Abstract: The cartridge has a recess 15 (Fig.1), formed in a lower surface of the cartridge, which engages with a support rod 117 when loaded into a carriage. The support rod is held between the lower ends of lifters 115 (Fig.12(b)) supported by projections 116. On loading, the cartridge is placed within the carriage and a cover 110 is closed (Fig.12(c)). The cartridge is then guided by an inner surface of the carriage such that the projection 116 reaches the vertical portion of a groove which allows the projection to descend vertically. This allows the cartridge to change its inclined orientation to a horizontal orientation using the inner surface as a fulcrum. As the projection nears the lower end of the groove, the cartridge descends vertically and is pressed downwards by a cantilever (113a,Fig.12(d)) into position such that a supply port 10 (Fig.1) engages with a needle (119,Fig.12(d)).

Inventor: INAGAWA EIJI
IPC: H04N1/32
Filed: 1998-09-18
Abstract: A facsimile apparatus 1 is disclosed comprising a fax section 2 and a line control board 3. The apparatus is connected to a personal computer 4 via a first telephone line 11 and to an external fax 6 via a second telephone line 12. The personal computer can transmit image data directly to the external fax by dialling the corresponding telephone number. If the external fax is busy and cannot receive the image data, the image data and the telephone number of the external fax are stored in RAM 23 of the facsimile apparatus. The facsimile apparatus can then attempt to re-dial the external fax until a connection is established. The facsimile apparatus then transmits the image data stored in memory to the external fax. When a connection cannot be established a message is sent to the personal computer to inform the operator that transmission has been unsuccessful.
