Patent FR-2273576-A1 (FR)
Title: Air purification by filtration through activated carbon - with automatic charging and variable carbon thickness
IPC: B01D46/30
Filed: 1974-06-06
Abstract: A method of filtering air through active carbon and automatically charging the carbon, incorporates the use of a storage hopper, a filter and a recovery hopper. The storage hopper is either placed above the filter, in which case the carbon flows by gravity, or to the side, in which case the carbon is charged by a screw conveyor, or similar. A valve, of any suitable king, e.g. a slide valve, is fitted between the hopper and the filter. The filter can be a panel, a pleated filter, circular or any other suitable form. A valve is fitted between the filter and the recovery hopper, which may be a trough with a screw conveyor. The valves may be operated manually or by a motor and reduction gear, with a programmer. Suitable for use in all air filtering installations. The replacement of active carbon when it is saturated with impurities can be carried out without stopping the operation, or removing the filter and possibly damaging it. The replacement takes only a few seconds and the operation is cheaper than with existing methods.

Title: Pliers type staple binder - has lever operating clinching jaws on frame
IPC: B65B13/34
Filed: 1974-06-28
Abstract: The binder has a pair of opposed clincher jaws pivotally mounted on a frame. The jaws are connected to and movable between open and closed positions by a sliding member which is moved by an operating handle pivotally mounted on the frame.

Title: Concrete mouldings mfr - using inexpensive mould liner made of polyester laminated with glass fibres
IPC: B28B7/36
Filed: 1975-01-28
Abstract: Concrete mouldings mfr. comprises pouring concrete into a vessel consisting of a mould-liner which has a continuous surface and is moulded in synthetic resin, and located in a strong supporting mould, the latter not possessing a precision surface because the surface of the mould-liner determines the dimensions and the appropriate surface finish of the parts being made. After moulding, the part is extracted from the mould liner without difficulty due to the lack of adhesion between the concrete and the liner which is made using a simple pattern and several successive layers of the liner matl. the pattern being used to make the required number of liners whereas the supporting mould has unlimited life. The mould-liner has a continuous surface, so the moulded parts have no flash due to joint-lines and the liners are simple to make and inexpensive, the supporting mould does not require a precise finish.

Title: Commercial vehicle hydraulic tailgate lift - with self blocking hydraulic servo motor to control inclination of lift
IPC: B60P1/44
Filed: 1975-02-25
Abstract: The hydraulic tailgate lift is controlled by sets of parallel levers and a large hydraulic servo under the chassis. A second, smaller hydraulic servo is fitted between the bottom of the lift and the levers to act as the diagonal strut for horizontal support. The servo piston is curved and rests against a bearing surface on the lever, so that when the servo operates it alters the inclination of the lift. This enables the lift to be sloped towards the ground for easy access of loads, and towards the lorry, during lifting, to prevent the loads from slipping off. A non-return valve inside the servo locks the servo in the event of hydraulic loss, i.e. severed pipe, so that the load does not slip off.

Title: Internal combustion engine fuel injection system - cuts off fuel supply when engine exceeds predetermined speed
IPC: F02D1/04
Filed: 1975-05-15
Abstract: Fuel is supplied to an engine by the pump (P) which is driven by an eccentric mounted on the camshaft. This ensures that the quantity of fuel supplied is proportional to engine speed. The stroke of the pump (P) is varied by capsules (CP, CT, CP1) which sense atmospheric pressure, temperature and manifold pressure respectively. The fuel flow from the pump can be cut off completely by the electro-magnetic by-pass valve (S). This valve operates when the engine speed exceeds the intended speed of the vehicle as for example during deceleration. The engine speed may be measured by a computer counting ignition impulses or by a tachometer.

Title: Brine pickling of meat - with a system for injecting an accurately measured amount of brine uniformly into the meat
Inventor: LANGEN BERNARDUS GERTRUDA
IPC: A23B4/28
Filed: 1975-06-17
Abstract: Uniform and precision metering of a predetermined quantity of brine to be injected into meat is achieved by injecting it at low but constant pressure, partic. in such a way that (a) the injection begins automatically as soon as a needle has to overcome the resistance of the meat and (b) the brine feed stops if the resistance disappears or if it rises sharply due to the presence of a bone in the meat. Method is partic. useful where separate loose pieces of meat of widely varying thickness are to be pickled, and ensures uniform brine impregnation.
