Title: Information duplicate distribution over a network
Inventor: NISHINA TOSHIHIDE
IPC: G06F17/30
Filed: 1995-04-18
Abstract: When definition information required for communication over a network is distributed to other information processing units that are connected to the network if this information is modified, this modification is relayed to the other information processing units, the contents of this modification are managed by a management list, and the differential between the information before said modification and the information after said modification is extracted by a differential extraction means and then transmitted. Transmission is executed to the partner in order from the definition information of the unit close to the side of transmission according to the positional relationship as seen from the side of transmission. At this time, the relay prompt information that prompts the relay of the modified information and the definition information that is to be transmitted are coupled into one data set, and then transmitted. Although verification and recording of the information being received are executed sequentially in the relay of the definition information, the subsequently received information is verified at the same time as the previously received information is being recorded.

Title: Charger apparatus eg for image forming apparatus
Inventor: OKAMURA TAKEHIKO
IPC: G03G15/02
Filed: 1994-03-17
Abstract: To reliably and uniformly maintain a discharging gap formed in the vicinity of a contact zone N between a charging member 101 and a photosensitive member 110, an electrostatic force is generated between the two members 101 and 110 which is greater than the mechanical force between them. The charging member 101 may be formed by a flexible film 102 with both ends supported by members 103 to 105. The film adopts the shape shown in fig 1B, i.e. radius of curvature of the film 102 in a zone P2 located downstream of the zone N in the rotating direction of the member 110 to be charged is smaller than the radius of curvature of the film 102 in an upstream zone P1. A formula for the maximum height of projections on the film 102 is developed, and examples of materials for the film are described. <IMAGE>

Title: Switched lampholder with lamp presence sensing
Inventor: LILLEY JOHN
IPC: H01R33/96
Filed: 1995-11-24
Abstract: A switched lampholder has sensing means 50 to sense whether or not the cap part 20 of a lamp 21 is retained in the holder 19, and a switch actuating means including an operating member 50 which causes the switch 43 to break the electrical connection to the lamp when the cap part of the lamp is not retained in the socket. The actuating means 50 moves the switch 43 between a make state and a break state and has a cam surface 57, 58 such that, when the switch 43 is in the break state, the switch encounters a first resistance to movement towards the make state when the cap part of a lamp is in the holder, and a second, greater, resistance to movement towards the make state of the switch when no such cap part is in the holder. The difference in resistance to movement of the switch is created by interaction between the switch 43 and either cam surface 56 of the operating member (inclined at about 45 DEG  to the vertical) when a lamp is in the holder, or cam surface 57 of the operating member (inclined at about 30 DEG  to the vertical) when the holder is empty. <IMAGE>

Title: Shape memory activation of steam vents
Inventor: KWOK CRENNER LUP HIN
IPC: F16K31/00
Filed: 1996-02-02
Abstract: A steam vent arrangement for a cooking utensil includes an aperture 10 in a lid 11 of the utensil.

Patent GB-2311851-A (GB)
Title: Wigner energy measurement
Inventor: PRESTON STEPHEN DAVID
IPC: G01N25/72
Filed: 1996-04-03
Abstract: Wigner energy in a graphite block 12 which has been irradiated by neutrons is measured by a rapid non-contact method. The surface 13 of the block 12 is subjected to a thermal perturbation from a heat source 16, and the subsequent surface temperature change * capital Greek delta *T is detected from the emitted infra-red radiation. The thermal conductivity k, and hence Wigner energy E, can then be calculated. The thermal perturbation may be applied by a laser, a flash lamp, by a hot air blower or by electro-magnetically induced currents. The thermal conductivity may be determined by measuring the temperature increase of an irradiated block at a preset time after a prolonged heating period and comparing it to that of a non-irradiated block. Alternatively, a very short heating period may be used. Further a single irradiated block may be used and a series of temperature change measurements taken at varying times after a rapid thermal perturbation.

Title: Milling method for liners extending into deviated wellbores
Inventor: DAVIS JOHN PHYLLIP
IPC: E21B7/06
Filed: 1996-07-11
Abstract: An apparatus and method of milling a liner 40 extending from a deviated wellbore 44 into a main wellbore 42 is disclosed. The liner 40 is inserted through a window and cemented in place with the cement extending back into the main wellbore 42. Spacers 54 are provided on the liner 40 to keep it away from the main wellbore 42 casing wall 46 to facilitate the proper operation of the washover tool 68. A top end taper is provided to help the washover tool reorient over the tubular liner 40 if milling requires more than one trip into the well. A diverter 50 is insertable prior to installation of the liner 40 to assist in getting the liner 40 to extend through a window. Upon milling through the liner 40 the washover tool 68 straddles the diverter 50 and latches into it to facilitate not only the removal of the diverter 50 but also the entrapment of any debris created by the milling operation. Suitable sealing is provided with the diverter 50 to keep the cement away from the latching mechanism during the cementing operation.
Patent GB-2317786-A (GB)
Title: Cellular communications system with narrow beamformed control channel
Inventor: CRICHTON PAUL
IPC: H04B7/26
Filed: 1996-09-25
Abstract: In response to a system access request on a wide area control channel RACH from a communication unit 42, a base station 32 having an adaptive array of antenna elements forms a directionally radiated narrowbeam control channel BCCH 51 to the unit and transmits control information so that the unit configures itself for communication to and from the base station on a narrowbeam traffic channel TCH. The control channel is not continuously transmitted and not capable of being received by all communication units in a particular cell thus reducing co-channel and adjacent channel interference. Each base station receiving the request transmits such a BCCH and the communication unit selects the strongest signal or the base station receiving the strongest RACH signal is used. The position of the BCCH can be optimised as the communication unit moves, by monitoring RSSI or BER at the unit and re-transmitting a narrow beam RACH signal when necessary for location indication, or monitoring the unit's transmissions at the base station. Alternatively the radiation pattern may be periodically oscillated or pulsed to adjust its width to gain information regarding the exact position of the communication unit. Handover is achieved by retuning to a new base station 26 which has been given the location of the unit 42 by the old base station 32 so that the new base station can direct its BCCH to it.

Title: Feedback rf power control with offset stored during off period removed during on period
Inventor: KINGSWOOD ANDREW CHRISTOPHER
IPC: H03G3/20
Filed: 1997-10-29
Abstract: A power control loop for a BTS (Base Transceiver System) is described which allows the power control to take into account compensating values which are detected during guard periods between signal bursts in an RF communication system. The power amplification factor is thus modified in dependence on the detected level of the amplified signal in a feedback loop, modified by the compensating value. This is used to remove an offset voltage Voff which exists in the guard period. Use in a TDMA system is described.
