Title: Hydraulic drive for bicycle - has cams on chain wheel to give pumping action for transmission to piston operated rack
IPC: B62M19/00
Filed: 1975-10-22
Abstract: The hydraulic drive for bicycles replaces the usual chain. The chain wheel (1) has the teeth replaced by cams which push a piston inside a cylinder (2) contg. incompressible liq. and create liq. pressure. This liq. is fed, via a steel pipe to another cylinder (3). The second cylinder is connected to a rack (4) just below the free wheel and engages the teeth on it to propel the bicycle. The system is fixed on each side of the bicycle to give alternating action. The rack cylinders can be protected in plastic or aluminium.

Title: Convertor for shaft rotation into electric signal - whose frequency is proportional to the speed of rotation
IPC: G01P5/07
Filed: 1975-12-17
Abstract: It comprises two pulse generators at an angle from each other, generating two pulse trains (UA, UB) whose phase difference corresponds to the angle between them, and frequency is proportional to the speed of shaft rotation. Each pulse train is applied to a store which delivers an output pulse train (U1) whose frequency corresponds to the shaft speed of rotation. The shaft can be pendulum-like rotated to-and-fro over a certain, large angle without the store delivering an output pulse. The system forms part of a heat energy metering system which uses resistance thermometers (RF, RR) in the forward and backwards flow lines.

Title: Material for vacuum packaging of cheese, etc. - includes plastic film, partic. polyolefin, permeable to oxygen but not to moisture
IPC: A23C19/16
Filed: 1976-03-25
Abstract: Packaging material for products possessing microbial flora consists of a perforated sheet suppor, associated, on at least one of its faces, with a heat-sealable plastic film which is highly permeable to oxygen but only weakly permeable to moisture. The support is pref. microperforated, and is a cellulosic film, a metal sheet, a metallised sheet of film, or a thermoplastic film. The heat-sealable plastic film is pref. made from polyolefin or its copolymers or ionomers. The packing is esp. useful or cheese whose quality depends on the maintenance of living microbial flora. It can also be used for foodstuffs where quality or appearance depends on a continuous supply of oxygen. Vacuum packing under materials impermeable to gas is prejudicial to microbial flora, but the new material maintains them in a living state whilst the beneficial aspects of vacuum packing are retained.

Patent FR-2310006-A1 (FR)
Inventor: SAKSHAUG EUGENE CLEMENS
IPC: H01T1/16
Filed: 1976-04-30
Abstract: The electrical overvoltage suppresser (10) contains a valve section (12) and a discharge-path section (14) in a housing, all of which is connected in series between a power transmission line (16) and earth. The valve section (24) and the discharge-path section (28, 30, 32) each contain a multiplicity of units which are stacked alternately in a row. The valve section has an exponent n greater than 10 of the current/voltage characteristic I = K.V<n>, K being a constant and I and V being the current intensity and voltage respectively at the valve block. As a consequence of the low value of the follow current which can in consequence be achieved, no additional current-limiting means are required on the discharge-path section. The discharge-path section is constructed such that it carries less than 1/5 of the voltage across the suppresser during a discharge. The suppresser is also suitable for high-voltage DC systems.

Title: Recovering useful gases and liquids from solid and liquid materials - involves transporting materials on perforate belt below radiant heaters
IPC: C02F11/13
Filed: 1976-10-08
Abstract: Appts. for recovering useful substances from solid or liquid materials includes a horizontal air tight enclosure with a removable top supporting on its underside radiant heaters which closely confront the upper run of a continuous perforate conveyor belt used to transport the material to be processed through the enclosure. In use, an inert static atmosphere is maintained in the space above the belt to prevent combustion of the material which is formed into a layer of adjustable uniform thickness on the belt, and gaseous and liquid products released from the material migrate through the belt into collection chambers located below the upper run of the belt. Gases are released from the chambers to atmospheric conditions at a level below the upper run of the belt to assist in maintaining a static atmosphere above the belt. The distance between the heaters and the belt is adjustable to allow variation of the heating effect. Used for processing of coal, oil, shale, tar sands, asphalt, peat, lignite, wood, sewage, crude oil, petroleum fractions and gilsonite. No vaporization or cracking occurs.

The stepping mechanism has contacts used for individual units of the machine, and a stepping motor drives the stepping mechanism.
Patent FR-2383006-A1 (FR)
Title: Forming and crosslinking high-density polyethylene - by very high pressure compaction, moderate heating and then further heating
Inventor: DENIS GERARD MARIE
IPC: B29C48/04
Filed: 1977-02-28
Abstract: Powdered thermoplastic prods. are prepd. using a cross-linking agent and high pressure exerted upon the mixt. as it passes along and through a nozzle, followed by cross-linking after it leaves the nozzle. High pressure si exerted along the nozzle upon the powdered mixt. contained in it, thus causing the mixt. to sinter; the mixt. is melted while still within the nozzle, but at a temp. not high enough to initiate cross-linking; after leaving the nozzle the material then passes through a bath fo molten salt at a temp. high enough to activate the cross-linking agent and thus cross-link the thermoplastics material. Pref. a piston is used to apply an axial pressure of 1000 bar along the nozzle. The process is partic. for high-density polyethylene, where normally the material could not be made sufficiently fluid in the early stages of passage through the nozzle without producing such a high temp. that cross-linking would occur prematurely. The method using sintering by application of high pressure enables the material to be compressed through the nozzle and carries out the preforming at this stage, without reaching the activation temp. of the cross-linking agent.
