Title: Piston engine cylinder head has auxiliary piston - free-moving in one, and damped in opposite direction
IPC: F02D15/04
Filed: 1974-06-06
Abstract: The auxiliary piston is co-axial with the main piston and is spring-loaded against the pressure in the cylinder. The auxiliary piston is provided with means which allow free movement in the direction of the force of the spring and act as a brake on movement in the opposite direction. These means preferably comprise an enclosed cylinder filled with liquid and containing a piston connected with the auxiliary piston.

Title: Fuel injector mechanism for engine suction tube - has electric air flow measuring means hydraulically controlling fuel flow
IPC: F02M69/26
Filed: 1974-09-23
Abstract: The mechanism is intended for application to combustion engines running on fuel mixture with external ignition and provides continuous fuel injection in the suction tube. The tube contains air flow measuring means and the throttle valve. The amount of fuel injected is in direct proportion with the air flow measured. The measuring means generate an electrical control signal corresponding with the air flow rate which signal in turn produces a hydraulic control signal which regulates the fuel flow in proportion to the air flow. The hydraulic control flow may be variable by a solenoid system arranged in a hydraulic pilot pressure circuit. The solenoid may act on a differential pressure valve, which is a flat-seated diaphragm valve, whose diaphragm is moved in the open direction by the varying force from the solenoid.

Title: Rotary compressor with screw rotors - improves efficiency by varying rotor tip clearance from inlet to outlet
IPC: F04C18/08
Filed: 1974-12-09
Abstract: The male rotor (8) has lobes projecting beyond the pitch circle. The female rotor (9) has matching helical recesses extending inwards from the pitch circle. When the compressor is not running the clearance between the lobes is a maximum but as the rotors expand due to the heat of compression, the clearance diminishes and this reduction is a maximum at the delivery end of the rotors and may be insufficient to prevent contact. To mitigate this effect the rotors are so shaped that the clearance when cold varies from a minimum at the inlet end to a maximum at the outlet.

Title: Solid fuel open fire for space heating - has hollow base with vertical partitions forcing air along zigzag path
IPC: F24B1/188
Filed: 1975-03-21
Abstract: The fire is built on a hollow hearth (1) which takes the form of a rectangular box let into the base of the fireplace. It is surrounded on its sides and underside by insulating material (3) to prevent undesirable loss of heat. Air from the surrounding room is blown into the box by a fan and leaves through an opening on the other side. It can either leave directly to the room containing the fire or deducted to other rooms. Vertical partitions within the hollow hearth divide it into a series of serpentine passages through which the air must flow. This prolongs the time spent by the air beneath the fire and thus allows time for it to heat to a higher temperature.

Title: Protective covering for the ground for industrial uses - comprises sand, a polymerisable support, e.g. synthetic rubber and a reinforcement of nylon fibres
IPC: E01C11/16
Filed: 1976-10-22
Abstract: A protective covering for the ground is resistant to the passage of heavy vehicles, and does not allow the penetration of contaminated water into the sub-soil. It comprises a hardening viscous mixt. spread over the ground, to a depth which may be of the order of five mm. Covering comprises an elastic matrix, e.g. a polymerisable paste or synthetic rubber which hardens at the ambient temp. and a reinforcement of nylon fibres. A cement powder may be added to the mixt. to absorb water given off during the polymerisation. Covering is strong and the covering contains embedded trapped particles of sand, which are not affected by washing action of rain and any toxic components therefore do not contaminate the sub-soil.

Title: Automatic bale tying apparatus - has baling press piston with passage for needle taking thread to knotter
IPC: B65B13/28
Filed: 1976-12-06
Abstract: The baling press has a piston with a passage through its front face through which a needle (10) can pass. When a bale (8) is formed to the required size, the needle is lowered, taking a thread from the upper bobbin and also picking up a thread from the lower bobbin.

Patent FR-2336598-A1 (FR)
Title: Vehicle disc brakes with differential control - has mechanical link to brake front wheels through reaction of rear brakes
IPC: F16D65/18
Filed: 1976-12-21
Abstract: The disc brakes of the front and rear wheels are braked by separate circuits linked by a mechanical link operated by the reaction of the rear brake. The rear brake calipers are on swivel mountings and as they brake they are dragged with the brake disc to press the mechanical link. This operates a second hydraulic master cylinder to operate the front brakes. The system ensures that the rear brakes engage immediately before the front brakes. The system is adjusted so that the front brakes operate at a set value dependant on the rear brake reaction, to achieve a properly balanced braking. No complex brake force distributors are required and the system operates safely with little chance of error.
Patent FR-2336673-A1 (FR)
Title: Specimen introduction appts. for liquid chromatography - has non-return valve to retain column liquid opened by needle
Inventor: AMSTUTZ RENE
IPC: G01N30/22
Filed: 1976-12-22
Abstract: Feed appts. for high pressure liq. chromatography columns comprises a housing, with feed inlet, into which the injection needle can be introduced. A non-return valve normally keeps the feed inlet closed and thus isolated from the high-pressure liq. in the column. To introduce a specimen, the injection needle is inserted into the feed inlet and forces back the non-return valve either by direct pressure of the needle tip upon the tapered point of the valve, or if the needle is short, by the higher pressure of the injected specimen. Previously where a polymer partition was used, and was pierced by the needle, after a certain number of uses this polymer started to absorb small quantities of specimens and thus contaminated further specimens. With the new arrangement, this difficulty does not arise. A satisfactory seal is provided by a succession of sealing plugs, each having a smaller internal dia. than the previous one, thus facilitating introduction of the needle tip.
