Title: Drying vegetable grains circulating in system - by alternately applying hot gas in short widely spaced periods
IPC: F26B3/06
Filed: 1974-10-29
Abstract: The system is particularly for vegetable grains which are passed through a drying zone where they come into contact with gas at high temperature, and are then rapidly extracted in order to undergo a rest period which is a multiple of that for which the grains are exposed to the gas. This cycle is repeated several times before the dried grains are discharged. The grains can be circulated continuously or cyclically, and the multiple value can be determined by the grain characteristics. There can be a column above a drying sleeve in turn surmounting an extraction sleeve, and a reservoir whose volume is a multiple of the grain volume in the drying sleeve. Means for heating the gas and delivering to the drying sleeve can be included together with a handling mechanism below the extraction sleeve, returning the grains to the reservoir or discharging them.

Patent FR-2270122-A1 (FR)
Title: Automatic lubrication cylinder for vehicle - has reduction gearing driving piston in replenishable lubricant chamber
IPC: F16N7/38
Filed: 1975-05-06
Abstract: The lubricant is contained in a cylinder and is pressed out of the cylinder by a piston whose rod is threaded on a shaft driven by a bevel gear which in turn is driven by a reduction gear train in the side of the housing, with the ultimate drive coming from the engine drive shaft. The amount of lubrication dosage is then proportional to engine life. The bevel gear is held in mesh by a spring and is pushed out of mesh by a spring loaded stop when the cylinder is empty. A flange at the far end of the piston rod touches the stop when teh lubricant is exhausted. A hand reset bevel gear operated by a spring loaded manual drive pulls the piston back, and also enables fresh lubricant to be drawn into the cylinder.
Patent FR-2311930-A1 (FR)
Title: Rotary piston IC engine - has stationary outer casing provided with valves and radially sliding vane engaging rotor
IPC: F01C1/356
Filed: 1975-05-23
Abstract: The rotor is mounted in the cylindrical casing. The spring loaded inlet valve is actuated by the cam through the push rod. As the space in the rotor passes the inlet valve, a fuel-air mixture is drawn into the engine. The sliding vave seals the space so that the mixture is compressed into the chamber. As the rotor continues to rotate the space comes in line with the chamber when the charge is ignited by the sparking plug. The increase in pressure due to the explosion exerts a resultant force to maintain the rotation of the rotor.

Abstract: A guide or presser roll for a textile machine is supported at each end by a spherical bearing assembly comprising a first bearing part having a spherical recess and a second bearing part having a spherical projection locating in the recess. The surfaces of the spherical projection and recess have spiral grooves to pump up and form a layer of lubricant (e.g. air, oil etc) between the two surfaces. One bearing part is connected to a stub shaft which does not pass through the roller. The roller is supported in both axial and radial directions by the bearings and is cheap to produce. The bearing does not wear quickly.

Title: Transverse cutter for cutting moving material - has cutter mechanism for reducing accelerations and for increasing format range
IPC: B26D1/42
Filed: 1975-09-30
Abstract: A mechanism for transverse cutting of a travelling strip, especially of corrugated cardboard has a rotating cutter driven by a motor with a control system. The accelerations of the cutter roller are kept very low without restricting the range of cutting format. The machine has at least one rotating cutter roller with a cutter which can move relative to the cutter roller (1). The cutter is connected to hydraulically actuated spring loaded piston (14) which slides within the cutter roller. The piston is controlled by a solenoid valve (11). The cutter is moved relative to the cutter roller so that the cutter does not carry out a cutting operation necessarily on each revolution. This arrangement results in lower accelerations than those met on using fixed cutters and the format range of cut sheets is greatly increased.

Title: Control circuit for vehicle window deicing heater element - has capacitor discharging to ultimately turn off transistor switch, preventing element being accidently left on
IPC: H01H47/18
Filed: 1976-05-03
Abstract: Transistorised circuit providing a defined time limit during which de-icing heating elements in motor vehicle windows are operated. The circuit prevents the de-icer being left switched on in error. The heater element (connected at four) is fed from the vehicle D.C. supply (4) via a relay (REL) operated two position switch (2). The relay itself is energised via two common collector connected transistors (T1, T2) which are driven into conduction by closing a control switch (6) allowing a delay controlling capacitor (C) to charge via the same switch in its OFF position (5). The heater can be switched off at any time by closing a further switch (8) which discharges the capacitor, immediately de-energising the relay.
Patent FR-2311999-A1 (FR)
Title: Solar energy collector section - has profiled blades reflecting radiation onto each other to increase efficiency of collection
IPC: F24S10/75
Filed: 1976-05-10
Abstract: The section is formed from a single extruded aluminium piece. It has a water tube (1) in which circulating water absorbs the energy collected and a collecting plate (2) extending above and below it. Curved blades project forward from the plate and are in one piece with it. The radii or curvatur of the top and bottom surfaces of the blades are such that all radiation falling on one blade is reflected onto the adjacent blade. Thus the section collects both direct and indirect radiation and the overall efficiency is increased. The section has a spigot (5) at the top and a slot (6) at the bottom by means of which it is joined to adjacent similar sections to form a complete collector.
