Patent GB-2300138-A (GB)
Title: Seal arrangement in vacuum bagging moulding
Inventor: BUTTERWORTH PETER
IPC: B29C43/10
Filed: 1995-04-21
Abstract: An apparatus for forming composite articles comprises a stretchable membrane 12 adapted to be placed over an article 34 to be moulded on a platen 16, and carrying a seal 14 around its outer periphery characterised in that the underside of the outer periphery of the membrane 12 adjacent the seal 14 is provided with a vacuum path 32. There is a vacuum valve 39 and the provision of vacuum path 32 12 ensures that the vacuum drawn through this valve extends completely to the outer seal, holding the latter into sealing contact with platen 16. In order to initiate the seal, a framework member 38 is pressed around the periphery to hold the seal 14 in contact with platen 16 while the initial vacuum is drawn. Thereafter the framework 38 can be removed. The assembly may then be placed in an autoclave as before. The fact that no permanent manifold is in position allows the apparatus of the invention to be used with small autoclaves where there was insufficient clearance for an apparatus of the type having a permanent manifold. Morover, less clearance between the stack and the edge of the platen is required.

Title: The cyclic adaptation of gear-changing characteristic in an automatic gearbox of a motor vehicle
Inventor: TINSCHERT FRIEDO DIPL ING
IPC: F16H61/02
Filed: 1996-03-29
Abstract: A procedure for the cyclic adaptation of a characteristic for the changes in an automatic gearbox includes gear-change strategies which determine correction values to adapt the gear-change in response to external influencing variables such as gradient or catalytic converter temperature. An algorithm correlates the measured values of the external influencing variables and is used to adapt the characteristic in respect of both the coordinate indicating speed of travel and that indicating engine torque. Separate correction values may be used for upward and downward gear-changes. The speed-related coordinate of the point on the characteristic map representing kickdown may also be subject to a correction value.

Title: An international freephone service
Inventor: CONNOLLY DAVID
IPC: H04M3/42
Filed: 1996-11-08
Abstract: A Universal International Freephone Number (UIFN) toll free service is provided and controlled by Originating Network Operator (ONO) and Terminating Network Operator (TNO) control units 11 and 12 respectively which communicate with each other using a separate data network. The control units arrange for the connection of toll free calls on the telephone network. The calls are monitored and billing records are created for each UIFN customer by the control units. The calls are established by the TNO control unit 12 and are treated as if the UIFN customer had themselves made a normal International Direct Dial (IDD) call. Information regarding the available UIFN's is stored in the control units databases and can be updated when required. If a UIFN is dialled and not immediately recognised, the ONO control unit can broadcast the number on the data network in an attempt to contact the TNO which holds that UIFN on its associated database. The number may contain a marker to indicate the service required eg. Voice only, fax or Internet access and this can be used to set up an appropriate channel.

Patent GB-2314149-A (GB)
Title: Thermosyphon refrigeration apparatus
Inventor: PEARSON STEPHEN FORBES
IPC: F25B41/00
Filed: 1997-06-13
Abstract: A refrigeration apparatus operable either by thermospyhon or vapour compression circulation of refrigerant comprises a condenser 2 for condensing refrigerant, an evaporator 24 for providing cooling effect and delivering a partially evaporated mixture of liquid refrigerant and refrigerant vapour. A receiver 30 is located between the evaporator and the condenser which collects excess refrigerant charge during thermosyphon mode, which might otherwise collect in the evaporator and inhibit operation thereof. During vapour compression operation liquid collecting in the receiver is evaporated away by heat transfer in heat exchanger 12 with liquid refrigerant at high temperature from the condenser and/or by heat transfer in fluid cooling means 48 with a portion of the warm fluid (e.g. water) which is to be cooled in the evaporator. In thermosyphon mode boiling of refrigerant in the evaporator is assisted by heat exchange from warm fluid to be cooled in a fluid heat exchange coil 54 located in the inlet manifold 22 to the evaporator, the heat exchange coil having a surface treatment to promote boiling.

Title: High-speed dynamic CMOS latch, flip-flop, and frequency divider circuits
Inventor: KANNO HIROSHI
IPC: H03K5/156
Filed: 1997-06-17
Abstract: A high-speed dynamic CMOS flip-flop comprises two cascaded dynamic latches and an output circuit P5 ,N5. Each of the latches comprises a CMOS transistor pair N1 P1 or P3,N3 with an interposed clocked transmission gate P2,N2 or P4,N4. Use of the transmission gates in place of a single transistor (figure 1) allows the dynamic storage nodes 001-004 to be charged and discharged rapidly and symmetrically to good logic levels. This permits an improved output waveform, and allows a higher operating frequency or lower operating current at a given frequency. The flip-flop may be used to divide the frequency of the clock signal CLK,CLKB by connecting the output QB to the input DATA.

Title: Partially pressure balanced BOP ram assembly
Inventor: LEVETT BRYCE A
IPC: E21B33/06
Filed: 1997-12-17
Abstract: A blowout preventer (BOP) having a piston (34) which is movable within a ram housing (22) in response to hydraulic pressure to control a ram shaft (36) which operates a sealing block (30), is characterised in that the ram shaft (36) is in the form of a hollow sleeve.
