Patent FR-2541408-A1 (FR)
Title: Force-multiplying operational drive device
IPC: F16H21/40
Filed: 1983-02-22
Abstract: Force-multiplying operational drive device intended for moveable and immovable rotary mechanical machines (electrical energy production). It consists of a circular arc-shaped force lever 1 whose work is to propel a double roller 3 on one and the same shaft, from the absolute neutral point; this lever having its fixed pivoting point at 2, one of these rollers sliding in a circular arc-shaped support framework 4, the other being connected to a connecting rod 4 serving to actuate the crankshaft 6, the lever 1 forming, together with the connecting rod 5, a second force lever called a "knee joint" whose work is, on the one hand, to relay the lever 1 at the moment at which it digresses and, on the other hand, to produce progressive power as the two branches move away up to the end of the journey. In order to ensure operation of this device, there has been provided, on the one hand, an arm 7 having its fixed pivoting point at 8, this arm 7 being connected to the lever 1 by means of a connecting rod 9, its travel being equal to that of the connecting rod 5, it may therefore be actuated either manually (wheelchairs) or by pedals (bicycle application), or by a pneumatic jack, or by an electric reduction motor, according to the various applications of the method, according also to the size and required power of the machine, by multiplying up the initial force by means of a group of devices, the first actuating the second by means of its own gain in energy and so on, hence the possibility of recovering the initial drive force.
Patent FR-2523711-A1 (FR)
Inventor: BARDONG HELMUT
IPC: F28D1/053
Filed: 1983-03-17
Abstract: A heat exchanger, in particular a radiator for motor vehicles is described, which consists of a plurality of tubes, arranged parallel to one another, for conducting the heat exchange medium, which open into an upper and a lower water box, and of gill-like plate-shaped heat exchange ribs, which are arranged perpendicular to the tubes and rigidly joined to the tubes. These heat exchange ribs are provided on their front edges with bent-over end parts which are laid like scales over one another and thus form side parts on which it is possible to arrange fastening devices for angle brackets. When the heat exchange ribs are placed on one another, the effect of this configuration is that the side parts are simultaneously formed at the same time and it is subsequently only necessary to attach fixing angle brackets at points where it is desired to fasten the radiator.

Patent FR-2537409-A1 (FR)
Title: Lightweight safety belt clasp
IPC: B60R22/12
Filed: 1983-12-12
Abstract: The safety belt clasp has a slit through which the belt is passed and a connector (11) for closing with a connecting mechanism in a belt lock. At least the connector is made of a non-tempered drawn steel wire, pref. wire made of acid-resistant non-corrosive steel. A clasp of this kind can be made from standard materials which are much more economical than those made from steel plate. There is no noticeable waste material left over after manufacture also resulting in lower costs. The clasp is made smaller and lighter so that the belt automatically retracts much more easily without the heavier clasp at the end. The wire (10) is bent so that it has a closed form with part extending along the edge of the slit which is biassed by the belt when tension is applied.
