Patent FR-2086249-A1 (FR)
Title: Plastic packaging containers prodn
IPC: B29C51/42
Filed: 1971-04-21
Abstract: Packaging containers are produced by deep drawing heated plastic film, which has at the beginning of shaping a different temp. at different positions in order to alter the extensibility of the film. The temp. of the film parts which are extended most during deep drawing is lower than the other parts. When the temp. of the film parts which are subjected to the greatest extension during deep drawing, is less than that at the other parts, then the reduction in wall strength of these parts is less than for a uniformly heated film. Consequently the container has a more uniform wall strength.

Patent FR-2224067-A1 (FR)
Title: Safety device for self propelled cultivator - uses double arm dead-man type pivoting beam to control fuel supply
IPC: B60K28/04
Filed: 1974-03-29
Abstract: The device consist of a pivoting beam, one arm of which is connected to a valve control while the other arm, which is brought into operation when the gear lever is put into reverse, cuts the fuel supply and stops the engine. When the machine is travelling in reverse the operator holds down a hand lever which operated on the first arm. This prevents the second arm from cutting the fuel supply. Should the operator fall, however, he would release the first arm, allowing the second arm to carry out its function of cutting the fuel supply and stopping the engine, thus avoiding injury to the operator.

Title: Aerodynamic sepn of mix including particles of plastic - in free fall through an ascending airstream, without centrifuging (PT180576)
IPC: B07B7/02
Filed: 1975-03-24
Abstract: Appts. for aerodynamic sepn. of mixt. including plastic particles liable to pick up random electrostatic charges, leading to erratic grading in a centrifuge, is for the recovery of re-usable material in the plastics industry.
