Patent FR-2241266-A1 (FR)
Title: Trousers with slimming effect on appearance - have each of two parts divided into three interconnected, oversewn sections
IPC: A41D1/06
Filed: 1973-08-23
Abstract: Trousers have each of their 2 parts divided into 3 longitudinally adjacent sides, permitting thinning down and tapering a silhouette by optical appearances. The 3 sides of each part are connected together by seams and are oversewn, giving the appearance of a geometrical figure, and provided with a means for facilitating walking. Pref. the geometrical figure is of 3-sides appearance. To facilitate walking, a slit placed at the front is formed by the termination of the join at several cm from the bottom.

Title: Multi-stage lifting jack - has supporting head locked at max height while lowering jack for reengagement
IPC: E02B17/08
Filed: 1974-05-30
Abstract: The jack lifts a supporting head, which is then locked in position at the maximum height. A component is then released from the head and sinks with the jack head, after which it is locked into engagement with the head again and the operation is repeated. The height of lift obtainable can be limited merely by the number of lifting operations it is desired to perform with the jack. The ground support plate can have a frame sustaining the jack at a height clear of the ground, the head having a frame whose components slide on the support plate frame. Locking and unlocking of the component can be effected by insertion and removal of a pin.

Title: UHF tuning for television receiver - permits multi standard working with single oscillator and tuned 1/4 wave line
Inventor: HULIN GILBERT
IPC: H03J5/24
Filed: 1974-06-26
Abstract: A tuner for multi national standard receivers, works in the UHF bands and has a single transistor connected as a modified Colpitts oscillator. Part of the resonant circuit is formed by a 1/4 wavelength line (7). One end is earthed and the other is connected to a variable capacity diode (9) that provides tuning for one standard as a supradyne oscillator. Standard changing is achieved by another variable capacity diode connected at a given point along the line. The circuit then operates as an infradyne oscillator. This gives a simple tuning circuit for UHF receivers working between the national standards of, say, France and Germany.

Title: Double acting anti-return drive - has double ended spring within cage to act as locking device
IPC: F16B1/04
Filed: 1974-08-08
Abstract: The cylindrical drive bar (1) rotates over a short spindle (8) and has a semi-cylindrical internal end (1c).

Title: Modular structure for house building - has a number of concrete cells which form a single room
IPC: E04B1/348
Filed: 1974-08-21
Abstract: The concrete cells used for assembling larger buildings have thin walls which are arranged side by side on each storey and a gap is left between the cells. These cells are connected by members which bridge these gaps. These connectors do not fully penetrate the cell wall and are used to ensure that the cell walls are not distorted when the space is filled with concrete, this also ensures that the plastering on the inner walls of the cells is not destroyed due to the pressure exerted by the concrete within the gaps. These gaps can be completely or partly filled with concrete. The building is erected by fitting the cells and then fitting the connectors into the gaps for prevention of lateral displacement of adjacent walls.
