Title: A device for suspending and/or lifting objects under water
Inventor: MILLIGAN DONALD LINDSAY
IPC: B63C7/10
Filed: 1982-11-27
Abstract: A device for suspending and/or lifting objects under water comprises a body having walls defining an at least partially enclosed space which, in use, is closed in its normally upper region and provided for receiving pressurised gas to provide buoyancy; means for permitting attachment of said body to said object; and a gas spill means to communicate said space with the exterior thereof at different vertical levels in the normal disposition of use of the body to permit the volume of air within the body to be controlled even with continued supply of pressurised gas. <IMAGE>
Patent GB-2112447-A (GB)
Title: Lifting device and a method of lifting for mesh sheets
Inventor: DAYSON ROBERT
IPC: B66C1/34
Filed: 1982-11-30
Abstract: A device for lifting bodies of mesh sheets comprises a shank 12 having two shank arms 12a, 12b. A pivot rod 10 is attached to the shank 12 midway along its length and extends perpendicular to the shank, which has a spike 16 at one end to engage the bundle, and a hole to receive a lifting member 30. The rod 10 is rested on the upper mesh sheet of the bundle with the spike 16 in the bundle. A lifting force applied by the lifting member causes the device to rotate about the rod 10 until the spike 16 engages the bundle, which then begins to rise. After use, a downward force on the shank arm 12a again rotates the device about the rod 10 and disengages the spike 16. The device can then be removed from the bundle. The pivot rod may define any of a set of pivot axes. <IMAGE>

Title: Fuel supply system for an internal combustion engine
Inventor: MOORE JOHN HOWARD
IPC: F02D41/24
Filed: 1983-03-14
Abstract: A fuel supply system for an internal combustion engine includes a mechanically actuated fuel pump 10 which has at least one electromagnetically operable valve 15 for controlling an operating parameter of the pump e.g. fuel delivery. A transducer 17 is provided which provides an indication of the position of a moving part of the pump which determines the fuel delivery. The system also includes an electronic control system 13 which determines the current flow to the valve and hence the position of said part. When the pump is manufactured there is created during its testing test data which is stored in a memory 22 which conveniently is secured to the pump. The test data in the memory is utilised by the control system during normal operation of the fuel supply system. In an alternative arrangement the test data may be in a form which can be used to update a memory in the control system 13 or supplied in a form 24 which can be inserted in a socket 23 in the control system 13. <IMAGE>

Title: Vehicle safety device
Inventor: DEVINE WILLIAM DAVID
IPC: G07C5/08
Filed: 1983-07-19
Abstract: A vehicle safety device comprises a switch (18) controlled sensor (10) operable to detect the movement due to fatigue, illness or the like of a vehicle driver from a normal driving position, and to activate a warning device (11, 12, 13) either audible (11) and/or visual (12, 13).

If not the clutch (22) may be disengaged, vehicle brakes (15, 17) applied, and/or engine stopped by interruption of fuel supply (27) or electrical supply (24). A programmable activating device (48) for the solenoid operated locks (47) of the vehicle (43) may immobilise the vehicle (43) and/or activate the warning device (11, 12, 13), the activating device (48) being operable in response to selection of predetermined digits stored in a memory of the activating device (48). <IMAGE>
Patent GB-2125726-A (GB)
Title: Controlling width of plastics film
Inventor: LOOSER GOTTLIEB
IPC: B29C48/92
Filed: 1983-08-16
Abstract: In producing tubular films by blow-extrusion or the so-called trapped bubble process the total air flow for internal cooling is governed by a primary air flow 153, 169, 154, and a secondary air flow 171, 14, 172, branched-off therefrom. The internal cooling is thus enhanced without mechanical calibration of the tubular film. The width of the film is monitored by sensor 18 and any deviation of the continuously measured actual width from a set or reference value of the width of the tubular film initiates a signal to valve 14 for controlling the secondary air. The flow rate of the secondary air is maintained at less than one percent of the flow rate of the primary air. The control of the secondary air is coupled via 140 and 142 or 143 and 144 with the adjustment of the primary air flow by 161, in order to adapt the latter adjustment thereof in case that the deviation of the width of the tubular film from the set or reference value is not eliminated by the secondary air control within a few seconds. <IMAGE>
Patent GB-2125533-A (GB)
Title: Solar energy collection system
Inventor: JESCH LESLIE F
IPC: F24D17/00
Filed: 1983-08-17
Abstract: A solar energy collection system, instead of using a closed primary loop in heat exchange relation with a secondary loop passes water to be delivered to the end user through the collector 3 prior to storage in a storage tank 6. The flow rate of water through the collector is varied by means of a pump 4 or valve so as to increase as the power available for collection increases. Furthermore unlike conventional systems where the amount of water in the tank 6 is maintained substantially constant, the level is allowed to vary within wide limits, the tank only being refilled when adequate power is available at the solar collector 3. <IMAGE>

Title: Vehicle deceleration sensing dual brake circuit liquid pressure control valve
Inventor: MORIYA MICHIO
IPC: B60T8/28
Filed: 1983-12-02
Abstract: A vehicle deceleration sensing type dual circuit brake fluid pressure proportioning valve assembly maintains even braking pressure in the event of failure of one of the braking systems and automatically sets a split point pressure in dependence upon the load on the vehicle. Two proportioning valve mechanisms (6, 6') are arranged coaxially within a valve body, with two plungers (8, 8') extending outwardly from a hollow liquid-pressure-operated piston (9). A common spring (12) pushes the plungers apart. Another liquid-pressure-operated piston (15) disposed coaxially with the two plungers, receives the outward end of one (8) of the plungers, and is moved rightwards by increasing inlet pressure PM acting in chamber (14) to compress the common spring (12) until the inertia valve (20) closes at a preset vehicle deceleration. On failure in either circuit piston (9) is displaced to prevent closure of the LH proportioning valve or delay closing of the RH valve. <IMAGE>
