Title: Distillation process using automated monobloc assembly - for recovery of soiled cleaning solvents from solns. with high solid content
IPC: B01D3/02
Filed: 1973-07-04
Abstract: Soiled solvents can be recovered from solns. with high solid content in a process which involves distillation followed by two-stage condensation. The appts. comprises a steel vessel for holding the soln. with internal heating coil, a finned air cooler, water cooled condenser and recovered solvent receiving vessel. The dirty soln. is distilled in the steel vessel and the pure solvent vapours are condensed in the air-cooler and water-cooled condenser before entering the solvent receiving vessel. Thermostats and/or level switches ensure the heating coil is isolated if the soln. level falls too low in the vessel, and a pressure switch and thermostat cut out the coil if cooling water flow is lost. Method is suitable for recovery of solvents used in e.g. paint workshops or printing industry, where solid particles enter the solution. Allows recovery of approx. 90% of solvent from solns. with high fine particle content. Can be batch or continuous process.

Patent FR-2271398-A1 (FR)
Title: IC engine with spring acting as crank - has ratchet output mechanism actuated by spring
IPC: F01B9/04
Filed: 1973-12-11
Abstract: The engine incorporates a piston-and-cylinder assembly, with injection, ignition and exhaust systems. There is no connecting rod assembly, this being replaced by a spring (3). The combustion can only be braked by the mechanical resistance of the spring, which thus stores all the resulting energy and releases it without loss through a rack and pinion ratchet mechanism (8). The output drive ratio can be varied dependent on the demand for power, thus making the firing less or more frequent by regulating the rate at which the spring expands again.

Title: Four stage fractionation of ground powders - using a mixture of stagnant and forced draught separators
IPC: B07B9/02
Filed: 1974-04-16
Abstract: Sepn. and fractionation of powders involves admitting the ground material first into a stagnant cyclone with a bottom outlet valve which exhauts material without allowing a countercurrent updraught. Fine dust entrained in the parent air flow is ducted away overhead for opt. pptn. filtration. The solids released by the cyclone dump valve drop towards a catch point but a countercurrent of fresh air return all but the heavier particles over a baffle into a hopper for a main fraction collection point. The particles heavy enough to fall in the first, stagnant, cyclone, but light enough to be carried in a forced air stream are drawn off for sepn. by a further cyclone discharging to a collection point for collecting the fine particles not entrained in the original air stream (6). The appts. is esp. for separating reground plastics etc and is suitable for semicontinuous operation, unlike conventional stack sieving.

Title: Portable self-closing liquid container of plastics sheet - is closed by sheets in contact at mouth
IPC: B65D33/00
Filed: 1974-05-06
Abstract: A container for liquids or other flowing media is consituted of two sheets of flexible, impermeable material, e.g., polyethylene, joined together by two opposite seams and having a mouth which is closed without the use of a separate stopper or clamp. When filled with liquid but not under pressure, the two sheets move apart from each other to provide the container void and taper towards one another at an angle of less than 90 degrees until they come into contact along a generally curved line; from this point onwards, in the normally filled but closed state, the two sheets lie in close contact with one another for a distance until the mouth of the vessel is reached. To eject liquid from the vessel pressure is applied to its sides; this causes the converging angle of the two sides of less than 90 degrees to be opened out so that the contact line forming the commencement of the sealed mouth is moved progressively forwards until it reaches the mouth and the vessel is thus open to discharge liquid. The container is any vessel for contg. liqs. which are to be discharged in portions are reqd. and where the vessel is to be closed again when desired without the use of a separate stopper, e.g. a portable drinking vessel.

Title: Resistive sensor for pyroelectric tube - has potential of back face of sensor raised to compensate ionic effect
Inventor: FELIX PIERRE
IPC: H01J31/49
Filed: 1975-12-23
Abstract: A potential compensating device for resistive sensors of pyroelectric tubes uses an ionic effect. The sensors are swept by a beam of electrons emitted by the cathode of the tube. The sensor then has a front face at an electric potential different from the potential of its back face. The back face potential varies according to the intensity of thermal rays received. The front face of the sensor is bombarded by ions which result from collisions between gas molecules and beam electrons. The ions then raise the potential of points of the front face of the sensor. The compensating bombardment is carried out during a phase different from the measuring phase. The measuring phases and the compensating phases alternate during operation of the tube. The device enables the back face of the sensor to be at a higher potential than the one obtained without its use.
