Title: Electrical socket
Inventor: REEVES STUART JAMES
IPC: H01R13/453
Filed: 1987-08-12
Abstract: A pluggable telephone socket comprises a housing (1,2) having therein a chamber (6) and an aperture (11) through which a pluggable telephone connector may be introduced into the chamber. A shutter (12) is movable between a closed position in which it obscures the aperture (11), and an open position in which it is displaced therefrom to allow entry of a pluggable telephone connector into the chamber (6). The shutter (12) has an angled face (16) such that movement of a pluggable telephone connector along a longitudinal axis and into the chamber causes the shutter (12) to be moved from the closed position to the open position.

Patent GB-2197387-A (GB)
Title: Air compressor
Inventor: RIDINGS JOHN
IPC: F04C29/00
Filed: 1987-10-23
Abstract: An air compressor driven by a 3- phase electric motor has a star-delta starter and, during its un-load condition, has the known facility to dump air whereby the power consumption of the motor is reduced during such a condition. In order to achieve a further reduction in the unload power consumption of the motor, the compressor is characterised by the inclusion of means, such as a pressure switch 26 or a timer (26', Fig. 4) forming part of a control circuit 23, 24 for causing the starter/motor to revert to its star mode when, during dumping, the air pressure in the delivery chamber 8 has fallen to a value at which the motor will run in a star mode without any tendency to stall. <IMAGE>
Patent GB-2214726-A (GB)
Title: Electrical adaptor
Inventor: JACOBS MICHAEL
IPC: H01R13/527
Filed: 1988-01-18
Abstract: The adaptor 20 provides a flameproof seal between LNG in a pressure vessel 12 and an electrical coupler 22 without nitrogen purging. Pins in the adaptor are connected to phase conductors 40 leading to an electric drive motor 16 of a submerged pump 14. The coupler connectors engage the opposite ends of the pins. Normal minimal leakage of LNG past primary O-ring seals passes out of the adaptor to atmosphere via a breather vessel 42. Excessive leakage causes pressure at an orifice restriction 127 and a pressure-responsive means responds to trip a circuit-breaker 28 to isolate the supply 26. A similar adaptor 54 can be used at the main tank 10. A valve means 44 allows testing and calibrating. A second outlet is directly connected to a breather vessel 42 and passes any leakage past secondary seals to atmosphere. The adaptor 20 comprises a housing containing a body of electricity insulating material through which at least one conductor extends. Seals 76, 78 exist between the housing and insulating material and seals 108, 110 exist between the conductors(s) and the insulating material. Passages 118 couple gas leakage past seals 108 to an annular passage 116 which receives gas which leaks past seal 76. The passage 116 is coupled to atmosphere. <IMAGE>

Title: Folding staging support assembly
Inventor: CRANFIELD JOHN HENRY
IPC: E04G5/06
Filed: 1988-03-01
Abstract: A folding staging support assembly for connection to upright members of scaffold structure comprises a staging bracket 26 pivotally connected to the upper end of a vertical bracket 10 which is itself releasably connected to an upright member. A brace 38 is pivotally connected between the bracket 26 and a sleeve 48 slidably mounted on the bracket 10. The sleeve 48 is fixedly supportable on the bracket 10 whereby the brace 38 supports the staging bracket 26 in a horizontal operative position. The bracket 26 may be pivotted upwardly to a substantially vertical inoperative position whereby the sleeve 48 slides upwardly of the bracket 10, the brace 38 thus pivoting also to a substantially vertical position adjacent the upright member 16. A pin 50 passes through an aperture in the sleeve 48 and an aperture 52 in the bracket 10 to retain the assembly in its folded inoperative position. <IMAGE>

Patent GB-2210125-A (GB)
Title: Insert
Inventor: BARNSDALE TIMOTHY JOHN RODERIC
IPC: F16B4/00
Filed: 1988-09-19
Abstract: The insert (10) is provided with at least one annular groove (16) in its outer periphery and with chamfered ends (14) for entry of the insert into a hole (30) in plastics parent material (32) with an interference fit so that the plastics material of the hole wall is temporarily displaced and then resiles into the groove (16) to retain the insert in position in the hole. Opposed shoulders (18, 20) of the groove (16) are sharp edged to shear or dig into the hole wall to also resist axial movement of the insert in the hole (30). The insert is primarily intended as an anti-creep spacer to take the compressive load of a bolt or like mounting of the component and so avoid or minimise such load on the plastics material which would otherwise cause creep of the latter and loosening of the mounting.

Title: Rigid-drawbar type trailer
Inventor: DOUGLAS PATRICK JOSEPH
IPC: B60G5/04
Filed: 1989-11-14
Abstract: A centre axle drawbar type trailer 10 has a tandem-axle wheel bogie set 14 which supports the chassis 12 in the region of the centre of gravity of the trailer 10. A rigid-drawbar 20 is attached to the chassis 12 and projects forwardly therefrom. The drawbar 20 is capable of extension and contraction between first and second positions. The suspension can be raised and lowered by varying the quantity of air in air springs 19. The trailer can thus be aligned with and positioned adjacent the load-supporting platform of a towing vehicle to facilitate load transfer between the towing vehicle and the trailer. The wheel arches are fixed to the axle beams to maintain a constant clearance around the wheels. <IMAGE>

Title: An optical system for the determination of the position of an object
Inventor: MORRISON JOHN MALCOLM
IPC: G01S5/16
Filed: 1991-01-09
Abstract: To determine the position of an object, photodiodes A - C on the object respond when illuminated by scanning horizontal and vertical fan-shaped beams emanating from source S. The beams are produced by the action of a laser beam through a Bragg cell or other electro-optic or acousto-optic device driven at a variable r.f. drive frequency. As an alternative, A - C may be replaced by light emitting diodes and the source S by a single photodiode. <IMAGE>

Title: Overflow filling for a siphon-discharge W.C. cistern
Inventor: LEE DAVID PETER
IPC: E03D1/38
Filed: 1991-01-15
Abstract: A WC cistern having a visual or audible overflow warning device, provides an indication of any increasing water level above the storage container's operating water level 12. The common siphon and overflow outlet 15, and alternative separate overflow outlet facility, enables overflowing water to be observed locally. As both overflow options allow overflowing water to discharge into the WC flushing pan, it removes the need for an external overflow pipe to be fitted to the storage container 10, simplifying cistern installation.   <IMAGE>

Title: A motor vehicle disabling system
Inventor: EALES GRAHAM DAVID
IPC: A61B5/18
Filed: 1991-03-12
Abstract: Referring to Figure 1, a disabling system comprises an Indicator Panel with eight indicators labelled according to functional features normally available in a motor vehicle, such as lights, windscreen wipers and hazard indicators among others. Two other indicators are marked Reverse Sequence and Start. Recurrent use of the brake pedal (BP) causes a clock (CK) to either illuminate the functional feature indicators rapidly or stop randomly with any four indicators on. When static, action is required corresponding to the indicators illuminated. When correct, the Reverse Sequence indicator will illuminate indicating that previous actions need to be reversed. If all actions are completed correctly before timer T1 expires, the Start indicator will illuminate and the vehicle will be enabled to start. If not completed correctly the whole procedure can be repeated three times, whereafter, if still unsuccessful, the vehicle is disabled for a number of hours. <IMAGE>
