Patent GB-2273396-A (GB)
Title: Electrical connector
Inventor: BOWMAN MARTIN ROBIN
IPC: H01R13/24
Filed: 1992-08-29
Abstract: An electrical connector consisting of two halves which self locate when brought together. The connector is contrived to facilitate separation and accept re-connection with other components of compatible design and dimensions. The first half consists of an insulated cartridge, containing a spring loaded rolling ball, housed in an engineered component. The second half consists of a conductive insulated ring housed in a second component which may be protected by a seal. When the two components are brought together and a mechanical joint formed, the ball makes contact with the ring producing an electrical connection. Should either component be rotated during connection, the ball will wipe clean against the ring face. On completion of the joint the optional ring seal encloses the joint giving complete protection. The body of the engineered component provides the second conductive current path. The connector is capable of reliable operation under hostile conditions eg. with a drilling string or crushing apparatus. <IMAGE>

Title: I.c.engine with combustion in communicating cylinders.
Inventor: MERRITT DAN
IPC: F02B23/08
Filed: 1993-06-25
Abstract: An internal combustion engine has first and second cylinders (12, 14), the first cylinder (12) having a larger swept volume than the second cylinder (14) and the second cylinder being formed in the crown of the first cylinder. First and second pistons (16, 18) are reciprocable respectively in the first and second cylinders (12, 14), the second piston (18) being formed as a protrusion on the crown of the first piston (16). The first cylinder has an air inlet (25) and an exhaust outlet (27) whilst a first fuel source (34) provides fuel to the second cylinder (14). The second piston has a crown (35) which is spaced from and connected to the crown (36) of the first piston and which has an edge (37) which is relatively thin in the axial direction compared to the spacing of the first piston crown from the second piston crown. This defines a combustion space (20) between the piston crowns and a side wall (14a) of the second cylinder (14) when the pistons are substantially at the inner dead centre position. The combustion space (20) communicates with both cylinders (12,14) during part of the expansion stroke. A spark plug (52) is provided communicating with the combustion space. Inhibiting means is also provided for inhibiting ingression prior to the pistons (16,18) arriving at or adjacent the inner dead centre position. This can take the form of a gap (128) between the second piston crown (35) and the second cylinder side wall (14a) with a peripheral groove (39) in the second cylinder wall at its upper end to enable the fuel/air mixture in the second cylinder (14) above the crown (35) to bypass the piston crown when the latter is at its inner dead centre position and enter the combustion space (20). The geometrical compression ratio of the engine, being the ratio of the volumes within the cylinders available for occupation by gas at the piston outer and inner dead centre positions, is chosen to ensure that the pressure and temperature reached in said combustion space near the end of the compression stroke are insufficient to cause spontaneous compression ignition of the fuel used. The ignition process is started with a spark and allowed to continue by compression ignition. After the spark ignition process begins, the flame raises the pressure and temperature of the gas in the combustion space sufficiently to cause compression-ignition of the remainder of the vaporised fuel as it ingresses into the combustion space under the action of the smaller piston and mixes with more air. <IMAGE>

Patent GB-2284728-A (GB)
Title: Low power, addressable data communications device
Inventor: ALLEN STEVEN PETER
IPC: H04W52/02
Filed: 1994-12-01
Abstract: An electronic tag 10 receives a data message (18, Fig. 2) that has a wake-up section (20) followed by a session section (22). A power manager 28 decodes the wake-up section (20) using a low power decoder 34 that remains energised during a standby state of the tag 10. When an ID detector 40 in power manager detects a predetermined ID code (26, Fig. 3) in the wake-up section (20), a switch 32 is closed to connect a power source, such as a battery 17, to a controller/transceiver 30 which may then decode, process and respond to the information in the session section (22). A particular tag may be uniquely addressed by a combination of the ID code (26) in the wake-up section (20) and identification data in the session section (22). The power manager 28 includes a synchronizer 38 that produces a sync signal in response to a preamble (24, Fig. 3) in the wake-up section (22). The synchronizer 38 goes to a low power state when the sync signal is produced. The sync signal also enables the ID detector 40, which has been in a low power state previously. The interrogation signal carrying the data message (18) encodes the wake-up section (20) at a lower data rate than the session section (22), so that the power manager 28 operates at the lower data rate thus enhancing the low power consumption in the standby state. <IMAGE>

Patent GB-2307658-A (GB)
Title: Open-ended spanner
Inventor: WILLIAMS JONATHAN
IPC: B25B13/46
Filed: 1995-11-28
Abstract: An open-ended spanner comprises two jaws 11,12 connected by a throat 14, the jaws being mounted on a handle 13, each jaw incorporating an inward facing flat, the flats being substantially parallel to each other such that the jaws will engage the flats of a nut, this arrangement being as found in a conventional open-ended spanner. However, a first jaw 11 is of conventional length whilst a second jaw 12 is substantially shorter in length than the first jaw such that, in use, with a nut engaged between the jaws the first and longer jaw can exert a turning force on the nut when the spanner is rotated in one direction, whereas the second jaw is too short to exert a similar turning force when the spanner is rotated in the opposite direction, thus creating in effect a ratchet-like action with no moving parts.
