Patent FR-2269662-A1 (FR)
Title: Automatic chain tensioning link - has two sliding wedges within tapering bore housing
IPC: F16G11/12
Filed: 1974-05-03
Abstract: Either a weight or a spring force can be used to take up slack. The weight of one of the elements (6) typically provides the take up force. The two sides (4, 5) of the link are slightly convergent towards the top and between them contain two wedges. One wedge (6) is attached (7) to the chain (13) and slides along one inner face (5) of the link. The other complementary shaped wedge (9) fits between the first wedge and the other face (4). At the other end of the link is the remaining connecting element (3). If the chain becomes slack, the block (6) slides down and the other block (9) slides down faster. This provides a "gearing" element which causes the parts to lock firmly together when chain tension is reapplied.

Title: Electronic brake control for trailer - with sprung inertial mass and magnetic detector to operate brakes without direct line
IPC: B60T8/17
Filed: 1974-11-15
Abstract: The trailer braking system is controlled by a special electronic inertial sensor to operate the brakes when the towing unit brakes, without any brake line connections between the towing unit and the trailer. A sprung inertial mass is displaced by the retardation and moves over a magnetic sensor, with the output of the sensor proportional to the amount of retardation. The output of the sensor controls the amount of braking control for the trailer brakes to prevent the trailer from jackknifing or overrunning. For added control, the circuit is coupled to the brake pedal by a single electrical connection so that the trailer brakes only operate in conjunction with the towing unit brakes.

Title: Moulding thin walled containers by intrusion and injection - increasing shot volume by fifty to sixty percent
IPC: B29C43/42
Filed: 1975-07-25
Abstract: Articles of high and low density polyethylene, etc., are produced on injection moulders with single or dual plasticising cylinders and nozzles, by a technique incorporating the following steps- 1) a mass of thermoplastic material is introduced into an extended mould cavity having a larger volume than that of the product, 2) a further quantity of thermoplastic material is fed in, 3) either before, at the start of or during the feeding of the second thermoplastic material, the volume of the moulding cavity is reduced to correspond to the dimensions of the finished article, and 4) a further mass of the first thermoplastic is injected so as to fill the mould inlet funnel. In the first step, the material is intruded with the plasticising screw held at a predetermined point. In the second the material is injected into the mould. The first material may form the skin whilst the second forms the core of a composite product. Makes it possible to produce articles with good surface characteristics, with the thinnest possible walls, e.g. 2 to 4mm, and with a flow/wall thickness ratio of >=30. The products have a volume, normally 50-60% more than the nominal size of the shot. With articles of a suitable profile and the right material, the excess may be raised to 100%.
