Title: Hydraulic control valve arrangement - contains direction valves, pressure compensation valves, pre-control pressure monitors, back pressure valves
Inventor: SUMIYOSHI TOSHINARI
IPC: F15B13/04
Filed: 1974-08-30
Abstract: A hydraulic system has valve units each with valves which may be parallel switched between the pump and the supply and return conduits of the control units, as well as between the latter conduits and the return conduit to the tank. Pressure compensation valves adjust the opening dependant upon the pressure difference above the corresponding direction valve. A second pressure compensation unit has a single valve between the pump supply and return conduit, to form an auxiliary connection to the direction valve. Pre-control pressure monitors between each direction valve, and the second compensation valve, monitor the fluid pressure and the valve position, and contain back pressure valves connected to each direction valve, to transmit the pressurised fluid from the valve under the highest pressure, to the second compensation valve. A pressure-compensated relief valve coupled to the monitors, releases a small amount of fluid from the monitors at any time, when under pressure.

Title: Windmill for charging compressed air reservoir - has blade angle varied by wind with limit parallel to horizontal axis of rotor
IPC: F03D9/02
Filed: 1974-09-12
Abstract: The blades (7) pivot between a neutral position in the plane of the rotor (6) on which they are mounted and an active one which is a function of the wind force, in one direction or the other. This pivot movement is limited to the point where they are parallel to the rotor axis (5). The rotor drives a compressor (8) charging a reservoir (2) which acts as the base of the windmill. a brake (9) can be provided to slow down the rotor when the wind is too strong. The blades can be fixed by elastic devices to the ends of the rotor spokes, limiting the pivoting movement if the wind is too strong.

Title: Continuous conveyor system for oranges - has pad containing granulated particles and carrying goods along horizontal path between loaders and ejectors
IPC: B65B25/04
Filed: 1975-09-16
Abstract: The conveyor is for the transportation of sensitive goods, esp. oranges, between a supply station, where the goods are supplied free falling, to an output station. The conveyor has a continuous row of support pads. Each pad has a cover contg. displaceable granulated particles. Before arrival at the supply station, the particles in each pad are subjd. to a displacement force, so that the pad is outwardly arched. The displacement of the particles due to the force of the falling object is utilized to accommodate and reduce the active impulse forces, and to form a seat for the object during movement towards the output station. To form the outward movement, the pads are turned upside down, when they return from the output-to the supply station via the lower section of the conveyor.

Title: Off-shore platform incorporating structure including hollow column - with hollow sliding element forming float supporting bridge, eliminating need for mechanical lifting equipment (BR 26.9.78)
Inventor: NOBLANC ALAIN GUY NOEL
IPC: E02B17/02
Filed: 1977-03-03
Abstract: An off-shore structure, designed to rest on the sea-bed or on a body of water to support industrial or scientific installations, comprises a hollow vertical column in which a hollow elongated element slides vertically. The element has a water-tight wall and bottom and forms a float which can support a bridge above the water. The structure can be ballasted so that it rests on the sea-bed or on a body of water. The height at which the element floats can be regulated and it can be fixed to the structure. The element can be submerged over most of its height and fixed temporarily in that position. The bridge can float on the water above the top of the element in that position and can be fixed to the element. The structure and the bridge are constructed separately on land and towed to their site. The structure is ballasted so that it rests on the sea-bed and the element is ballasted to bring its top just above the surface. The bridge is brought over the element, ballast is taken out of the element so that it lifts the bridge above the water, and the element is fixed to the bridge and to the structure. Problems associated with mechanical lifting equipment are avoided.
