Patent GB-2009686-A (GB)
Title: Marine access systems
IPC: E06C9/14
Filed: 1978-12-13
Abstract: A system for the safer transfer of persons between vessels or between a vessel and an offshore structure. The system may be a flexible elastic structure which in use is hung between and attached to both vessels used in the transfer and tolerates relative motion of the vessels. In one form the structure is a tube in complete or skeletal form with internal projections to act as rungs or treads. In another form the structure is a ladder with elastic sides (4a, 4b) and stiff treads (3) and capable of about 15% lengthwise extension. The elasticity is very useful in easing the deck-to-ladder transition on a small vessel as the ladder-foot (2) can be held in a steady relation to the deck, not hitherto possible. <IMAGE>

Title: Laundry bleach system
IPC: D06F39/02
Filed: 1980-01-31
Abstract: A system for supplying washing solution, for example bleaching solution, to washing machines utilises a closed supply loop 1 which incorporates a stock tank 3 for containing reduced bleaching solution, a pump 4 for continuously circulating bleaching solution from the tank 3 about the supply loop 1, and outlets 5 for enabling bleaching solution to be discharged from the supply loop 1 to the washing machines.

Title: Telephone line circuit; current supply arrangements
IPC: H04M19/00
Filed: 1980-05-02
Abstract: A telephone line circuit comprising a terminal 1 for connection of a wire of a subscriber's line for applying thereto a line current which is determined by the impedance of the subscriber's line and an alternating current 4 which is superimposed on the line current, the circuit further comprising an amplifier 2 and a current injection circuit 11, 12 connected to the output of the amplifier for supplying a portion of the line current, determined by the impedance 12 of the current injection circuit, the amplifier supplying the remaining portion of the line current.

Patent GB-2057065-A (GB)
Title: Fuel injection pumping apparatus
IPC: F02M59/10
Filed: 1980-06-24
Abstract: A liquid fuel injection pumping apparatus comprises a reciprocable pump plunger 16 operable by a tappet- assembly 17 and a rotary cam 12. The tappet assembly includes a cylindrical body 35 slidable within a bore 18, the body 35 carrying a cross pin 38 which supports a roller 37 engageable with the cam. The cross pin has radiussed ends so that if it moves axially while exposed beyond the end of the bore it will engage the bore and move axially to its correct position. With cams designed to give maximum plunger movement the pin is exposed for an appreciable time and heavy wear of the pin and bore can occur. The cam is therefore designed to allow outward movement of the plunger but then to hold the plunger until just before inward movement of the plunger is required to take place. Whilst the plunger is held the filling port of the pump is at least partly uncovered. The cam has a trailing flank 41 which comprises a first part 42 during which the plunger can move outwardly, a second part 43 during which the plunger is held against outward movement and a third part 44 which allows the full outward movement. <IMAGE>

Title: A device for developing control of sphincter-type muscles
IPC: A63B21/008
Filed: 1981-01-14
Abstract: A device for assisting a person to exercise and improve his or her control of sphincter-type muscles includes an elongated support member which carries or in part defines an annular cuff. The member and the cuff are in communication and are filled with a fluid. The cuff is dimensioned and positioned to be capable of sensing small movements of the muscle of interest. The device has means whereby the cuff can be filled to a predetermined pressure with fluid. The said means may consist of a pre-inflated and pre-pressurised bulb or chamber 224 connectible to the interior of the member and hence to the interior of the cuff by a valve 230 located between the bulb and the member. Alternatively the said means may consist of a contractible chamber in fluid communication with the interior of the member via a non-return valve, the chamber being associated with a stored-energy means which upon appropriate triggering, releases its stored energy so contracting the chamber and urging a portion of the fluid therein into the member and the cuff. <IMAGE>
Patent GB-2070898-A (GB)
Title: PCM detector
IPC: H04N9/85
Filed: 1981-02-25
Abstract: In a pulse code modulation (PCM) detector, an integrator integrates the central portion of each signaling interval of a PCM input signal for a time less than the reciprocal of the PCM baud rate. Means responsive to the integrated signal or a manifestation thereof performs a comparison operation at the end of the integration period and stores the result until the end of the next following period. The integrator is reset between integration periods when transitions of the signal are likely to occur, whereby immunity to PCM signal amplitude variations and transition edge distortion is enhanced and the probability that the integration will be monotonic is enhanced, thereby reducing the detector error rate. Preferably a change source provides a predetermined quantity of charge continuously or in discrete amounts to the integrator during the central portion of each PCM signaling interval.
Patent GB-2073832-A (GB)
Title: Safety Device for a Manually- operated Change-speed Gearbox
IPC: F16H61/16
Filed: 1981-03-02
Abstract: A safety device for a manual gearbox having a plurality of ranges of gears prevents selection of one of the ranges at such times as engagement of a gear within that range would cause overrevving of the associated motor. In the safety device, a centrifugal body (10) is received in an annular synchronizing body (13) and has a radial bore (11) in which is a spring (12). The spring at one end acts on the bottom of the bore and at the other end on a pressure member which abuts a recess (4) in a sliding sleeve (3), the position of which determines the gear range selected. The recess (4) has a stop (5) at one end, and if cengrifugal force overcomes spring action the centrifugal body is forced outwardly of the synchronizing body and an attempt to select a lower range of gears will be prevented by interaction of the centrifugal body with the stop. <IMAGE>
