Patent FR-2273466-A1 (FR)
Title: Tree felling machine - with cutter and gripping arms on frame on end of jib arm, has two hydraulic cylinders for moving sideways, backwards and forwards
IPC: A01G23/08
Filed: 1975-06-05
Abstract: A first hydraulic cylinder moves the device sideways; and a second hydraulic cylinder moves it forwards and backwards. Between the inlet and outlet pipe of each hydraulic unit is a control valve with a first and second position for closing and opening the duct between the two pipes. After the gripping-arms have fixed round a tree, a valve is in a closed position, and momentarily opens before the cutter operated. A cutter contact closes the circuit of a time-switch relay in one contact position of which is enclosed a circuit for the valve, operating a return force. In the other contact position of the relay, the operating circuit is opened and the release circuit for the cutter is closed.

Title: Measurement of moisture content of cereal grain - is effected by capacity meter employed as humidity meter
Inventor: BUGNOT DENIS
IPC: G01N27/22
Filed: 1975-07-02
Abstract: The moisture content of a given mass of cereal grain is determined from capacitive and resistance measurements of the grain since the electrical model is that of a capacitive resistive dipole. The poles of a container for a mass of grain (1) whose electrical analogy is a capacitor (C) in parallel with a resistor (R) are connected between the output of an operational amplifier (2) and one of its inputs. A triangular waveform (Ve) is supplied from a generator (3) to the other input on the amplifier and a detector circuit (8-20) measures the value of the voltage across the measuring resistor (r) when the waveform passes through zero volts to determine moisture content. The circuit corrects for measured value of container capacity.
Patent FR-2278397-A1 (FR)
Title: Treating grain with supplementary additives - by partially softening to prevent fracture, pressing to cause cracking and treating with a soln. or suspension of the additive
Inventor: LEWIS VICTOR M DR
IPC: A23L7/10
Filed: 1975-07-17
Abstract: Food products are made by (1) partially softening edible seeds (grain) to prevent their fragmentation under pressure, (2) pressing the seeds to cause cracks and fissures to form in them and (3) applying an additive to the seeds to impregnate them by way of the cracks and fissures. This method allows rapid and continuous treatment of a wide variety of seeds and grains, and permits incorporation of water-soluble additives and emulsions and suspensions of insoluble substances which penetrate the cracks and fissures in the seeds and thus overcomes the problems associated with the coating of seeds and grains as in known processes. Suitable starting materials are e.g. wheat, maize, rye, lentils, sorghum, rice etc.

Title: Drying articles with a solvent mixt. - contg. halogenated hydrocarbon and alcohol or ketone, then exposure to vapour of halogenated hydrocarbon
IPC: B01D12/00
Filed: 1975-09-26
Abstract: Objects are dried by treating with a liq. mixt. comprising >=1 halogenated hydrocarbon (I) and >=1 hydrophilic cpd. (II) which is an alcohol or ketone. The treated articles are then exposed to the vapours of a halogenated hydrocarbon (Ia). (I) and (Ia) may be same or different and are pref. trichloroethane, perchloro- or trichloro-ethylene or a trichlorotrifluoroethane; specifically they are both 1,2,2-trichloro-1,2,2-trifluoroethane. Pref. (II) are 5C alkanols or RCOR' (R and R' 5C alkyl) and make up 1-40 wt.% of the mixt. An appts. for drying objects by this process is also new. Inclusion of the inexpensive (II) reduces cost of the drying mixt.; only a single heated vat is needed; the equipment used is simple and by choice of solvents all metal or plastics articles can be dried even if they are dirty.
Patent FR-2326462-A1 (FR)
Title: Charging preheated coal into a coke oven - by starting and finishing the operation at much lower speeds
IPC: C10B31/00
Filed: 1975-10-02
Abstract: In an improved technique for charging a coking oven with preheated coal by means of a hopper and a rotary distributor such as a honecomb screen or a worm at the bottom of the hopper, the speed of rotation of the rotary distributor is reduced relatively to its normal speed, at the start and at the finish of charging. At the commencement of charging, the speed of rotation is reduced to two to four times less than the normal running speed, and is then raised gradually to the full speed until a few seconds before the conclusion when it is reduced again. Method prevents the considerable increase in pressure in the retort system at the start and finish of charging in the conventional manner, which may lift the plugs and the valve opening the distillation duct to atmosphere releasing tar laden gases.

Title: Vacuum operated floor cleaner - has brushes applying liquid detergent with pivotable inverted U-shaped vacuum heads
IPC: A47L11/30
Filed: 1975-10-23
Abstract: The manually propelled mechanical floor cleaner uses a brush action with the application of liquid detergent, and includes vacuum extraction of soiled liquids. The vacuum extractor heads may take the form of two inverted channel sections resp. locating transversely fore and aft of the machine. The heads pick up either free dirt or soiled liquid. The heads also effect partial drying of cleaned surfaces and can be pivoted relative to a transverse axis. The pivoting action inclines the leading head away from the machine, makes a contact seal with the trailing channel leg, and is effected by a system of cables and springs. The leading top edge of each head may be displacable by a cable.

Title: Electrolysis system for oxidation reactions - using extended surface electrode formed by conducting particles in cell
IPC: C25B9/16
Filed: 1976-12-21
Abstract: Electrolysis system for manufacturing chemicals are housing round which an electrolyte is circulated. Inside is a particulate electrode with insoluble conductor lines. Means of removing sludge and electrolysis products are provided. The particles are made from an electrically conducting material. The housing has electrically insulated walls contg. the particles into which are mounted the insoluble conductor lines. In contact with the electrolytes, the particles form layers of reduced conductivity. When a potential is appled to the conductors, this creates a bipolar effect on each of the particles. the housing is of reduced dia. in its upper section causing an acceleration of the electrolyte upwards propelled by the gas generated during the process. One of the conductors can be movable. Used with electrolytic processes making oxidising agents such as permanganates, dromates, dichromates and of Cl-O cpds. such as chlorates and hyporchlorites. Provides a compact electrolyser of high capacity which operates like a number of individual baths linked in series. A strong current can be applied to a large electrode surface on the particles, and use is made of a bipolar effect.

Title: Continuous flat plastics article prepn. - with common carrier tape turned for bilateral use of plastic double foils
IPC: B29C69/00
Filed: 1977-04-14
Abstract: Flat articles, made of plastic foil and welded at the contours, are produced by feeding a double plastic foil on a carrier tape into a welding and separating unit. The compound tape is then turned through 180 degrees by guiding it over a drum at 45 degrees to the direction of motion. In a second welding and separating unit, a second double plastic foil is applied to the other side of the carrier tape and used for the prodn. of a second line of articles. Used for mass prodn. of surgical gloves, bags or similar contoured articles with a welded joint on the contours, made of a plastic such as polyethylene. This reduces the mfg. costs of mass-produced articles by doubling the prodn. rate (using two welding units) and by saving high-quality carrier paper (applying articles on both sides of it).

Title: Cigarette handling conveyor belt reservoir - has horizontal buffer reservoir discharging horizontally into L=shaped belt conveyor feed system
IPC: A24C5/32
Filed: 1977-06-09
Abstract: The cigarette handling arrangement has a reservoir conveyor (35) made up of a belt conveyor (38) under a cover, which discharges horizontally between horizontal belt conveyors (1, 2) at one end at a higher level than the cover. The cigarettes are then discharged vertically downwards between further portions of the belts, which follow an L-shaped path.
