Title: Hill holder control system
Inventor: WOOLVIN PHILIP
IPC: B60T11/10
Filed: 1994-10-21
Abstract: A hill holder control system for a vehicle hydraulic braking system in which a valve (1) has an inlet (9) connected to a pedal-operated source of braking pressure and and outlet (10) connected to one or more brake actuators. An inclination sensitive valve member (14) is capable of closing off a valve seat (13b) to trap brake pressure in any brake actuator connected to the outlet and a command means (11, 15, 18, 19) is provided which is operated from an associated clutch pedal and which renders the valve member (14) operative to close off the valve seat when the clutch pedal is operated. The control system also includes a valve member disabling means (31) operable to unseat the valve member (14) from the valve seat (13b) to release any trapped brake pressure, and an electrical control circuit (40) including a "brakes operating" condition sensor (35), a "brakes released" condition sensor (34) and a clutch bite point condition sensor (36). The electrical control circuit (40) is arranged to operate the disabling means (31) when the three sensors (34, 35, 36) indicate the simultaneous presence of all three conditions to ensure a timed release of brake pressure on re-engagement of the clutch. <IMAGE>

Title: Lockable electrical plug and socket
Inventor: BRODIE JAMES STUART
IPC: H01R13/639
Filed: 1996-05-14
Abstract: A plug and eg wall socket are automatically locked together when interengaged and switch off the supply and reset the shutter (figure 4) when disengaged. In one embodiment, a notch or hole in one or more plug pins is engaged by a wedge or post of the socket shutter. A press button or key releases the shutter, which engages a tongue (figure 17) to switch off the supply. The notch may be provided in a removable non conducting pin (figure 10). Alternatively, a sprung latch can be used, or a notch in the face of the plug is engaged by a sprung tongue on the socket, which allows a conventional plug to be used if required, without locking. A coil around a female terminal can be fed with dc via a rectifier in the socket, to electromagnetically lock a plug pin in engagement.
Patent GB-2314018-A (GB)
Title: Partition or door mounted fire extinguisher
Inventor: HENMAN KENNETH MICHAEL
IPC: A62C31/28
Filed: 1996-06-14
Abstract: A small fire in a space can become a big fire when the supply of oxygen is increased. For example, if an armchair is on fire in a closed room, it may smoulder slowly for some time. But, if the door is opened, the chair, or the hot particulates and gases given off by the chair, may catch fire violently (in the latter case due to a phenomenon known as flashover). It would be useful if the danger of opening a door or the like could be reduced without the expense of a full sprinkler system. To achieve this object the present invention provides an arrangement for mounting in a partition, for connecting one side of the partition to the other, the arrangement being such that a supply of fire-fighting fluent material may be passed through it.
Patent GB-2304357-A (GB)
Title: Pressure-boost device for downhole tools
Inventor: MYHRE MORTEN
IPC: E21B23/04
Filed: 1996-08-13
Abstract: A pressure intensifier is used to boost the pressure from a downhole pump for operation of a downhole tool such as a packer or bridge plug. The pressure intensifier employs an unbalanced piston 48 which is initially fixed in a run-in position. The piston 48 has a flowpath therethrough in which is mounted a check valve 44. Initially, pressure is applied to above and below the piston 48 which results in an unbalanced force on the piston 48 due to its configuration. Flow to the tool initiates its actuation at this time. When the unbalanced force reaches a predetermined level, the piston 48 is no longer fixed to the housing and begins to accelerate. Acceleration of the piston 48 closes the check valve 44 due to the sudden decrease in pressure behind the check valve and an increase in pressure in front on the check valve as the fluid volume in front of the piston 48 is compressed. Due to the proportional relationship between pressure and area, a magnification of force originally delivered by the pump is achieved for completion of the setting of a downhole tool such as a packer or bridge plug or the like.

Title: Ink transfer printer using a porous roller covered by a heat deformable shape memory resin film having expandable through-holes
Inventor: SUZUKI MINORU
IPC: B41J2/325
Filed: 1998-10-09
Abstract: The printer includes an ink roller 10 which comprises a porous roller 3 and a shape memory resin film 2 (e.g. polyurethane) which covers the roller. The film is provided with expandable inclined through-holes (21,Fig.3C). In operation, the roller rotates in a clockwise direction such that a sheet P is nipped between the roller and a platen 8. A thermal head 7 selectively heats parts of the deformed film, according to image data, to a temperature higher than the glass transition temperature to change the shape of the respective through-holes of the selected parts (Fig.3C). Ink is then transferred from the porous roller onto the sheet P via the expanded through-holes. A sheath heater 9 heats the entire film in the axial direction of the roller to a glass transition temperature (Tg.Fig.2) or higher, which opens the through-holes sufficiently (Fig.3A) to allow ink to pass therethrough. A roller 11 compresses the film and a fan 13 cools down the film to a temperature lower than the glass transition temperature to collapse and close the through-holes (Fig.3B). A roller 12 cleans any excess ink from the film before it is heated by the head again. The operation is repeated until the image has been completed.
