Patent FR-2295275-A1 (FR)
Title: Hydraulic control system using piston separating chambers - has control unit for electromagnetic valves adjusting chamber pressures
IPC: F15B11/08
Filed: 1975-12-19
Abstract: A piston (5) separates two pressure chambers (11, 12) to which electromagnetic control valves (32, 34) are connected via conduits (31, 33). These valves are controlled by a current from a control unit (C) and are connected to a reservoir (22). The chambers are also connected via conduits (25, 28) through anti return valves (27, 30) and throttle valves (26, 29) to a pressure source. The throttle valves each comprise a stop or variable throttle valve which are operated by differences of pressure in the conduits when the control valves are closed. Actual pressure is detected and compared with a nominal value in the control unit.

Title: Coin separator for coin counting mechanism - has coins passing through slot in rotating plate into guide chute
Inventor: NICOLAS BEZSILKO
IPC: G07D9/00
Filed: 1976-01-21
Abstract: The coin separator is used in a coin counting mechanism for preventing more than one coin being supplied to the counting mechanism at a time. The coins are supplied to a rotating plate, surrounded by a fixed ring and pass through a slot into a guide chute, delivering them to the counting mechanism. The slot for the coins is provided in the fixed ring around the rotating plate, at a height limited by an adjustable block. The height of the slot can be corrected by a thin block (42) when the separator is used with thin coins, to prevent two coins passing through together.

Title: Universal drive shaft coupling - has one yoke and splined sleeve formed integrally from rolled sheet
IPC: F16D3/26
Filed: 1976-03-05
Abstract: The universal shaft joint has one or more jaws with tubular portions made either by rolling a flat cut-out sheet or drawing out. It is shaped at one or both ends to form one or both halves of the jaw. The internal wall of the tubular portion has splines or protrusions for rotary drive transmission. The jaw can be formed by a length of tube, shaped at one end, or by two half-shells assembled by two axial welds to form the tubular portion. One end of each half-shell is shaped to form a half of the jaw. Alternatively, a section of flat sheet metal can be cut out to form the jaw halves, and then rolled to form the tubular part.

Patent FR-2354721-A1 (FR)
Title: Cutting animal skins for fur coats - esp. female mink to make full use of tail length
IPC: A41H41/00
Filed: 1976-06-17
Abstract: Symmetrically, one at each side of the tail, there are cut from the animal's back skin two wedge-shaped pieces which are acute-angled towards the front of the back skin. The two wedges are displaced tailwards, sewn to the sides of the tail and the two notches in the back skin are closed and sewn up. Instead of cutting out two wedges, an animal skin can be bias cut in parallel strips extending from a min-section of each side of the skin to areas between the tail and each rear leg. The strips are displaced tailwards and inwards along the bias angle, thus making full use of the tail length and reducing the max. width of the mid-section. Used for preparing animal fur skins, esp, mink, for making up into garments.

Title: Toilet pan UV disinfecting mechanism - uses switch adjacent to seat hinge to operate radiator when lid is lowered
IPC: A47K13/30
Filed: 1976-06-17
Abstract: The disinfectant device for the toilet pan leaves no residual traces, and operates by ultra violet rays on the inside surface of the pan on the top and on the lid. The ultra violet source is contained in the toilet lid(s). A second disinfectant lid folds down over the seat. When the lid is lowered, a switch lights up the ultra violet tubes or lamps.

Title: Guide roll track for continuous casting wide steel slabs - using hydraulic cylinders for individual clamping of each pair of rolls
IPC: B22D11/128
Filed: 1976-07-16
Abstract: Guide roll chassis for a continuous casting plant mfr. steel billets or slabs, esp. a chassis contg. driving and straightening-rolls located in pairs with individual adjustment of the gap between each pair of rolls. Each roll is mounted in a pair of bearings located on a traverse, and the two traverses are aligned by comb-shaped guides. The two traverses employed for each pair of rolls can be moved towards or away from each other via hydraulic cylinders; and at least the traverses carrying the idling rolls can be adjusted by thrust pieces on the frame of the casting plant. Both traverses pref. project outside of the comb-shaped guides, where the hydraulic cylinders are located near the ends of each traverse. Used e.g. for casting slabs with widths exceeding 2.2 metres. Each pair of guide rolls can be individually stressed to prevent the semi-solid slab bulging during the casting process; the roll gap can rapidly be altered to suit different slab widths; and the rolls are easy to replace.

This causes a modulated surface field, over the face (11) of the semiconductor element (10) onto which the light beam (Ii) is directed. The semiconductor material is such that one inter band transition is of the same order as the photon energy of the light beam. The semiconductor element (10) may be an IMPATT or TRAPATT Gunn diode, with an oscillation at a frequency of 1 Giga Hertz set up when a voltage above 8 volts is applied, with a superimposed modulation voltage provided by a 5 volt source (13) at a frequency of 100 Mega Hertz.

Title: Reproduction of pictures in relief - uses flexible film which is deformed by matrix and then filled with hardenable material
IPC: B44F11/02
Filed: 1977-06-02
Abstract: Coloured pictures can be reproduced in relief by first covering the flat surface of the copy with a thin layer of material which can be elastically deformed. A matrix is then prepared which embodies the required areas in relief. The matrix is then pressed onto the elastic layer until it is deformed to match the contour of the matrix. The matrix is then withdrawn and the reverse surface of the copy is covered with a material which fills all the depressions and subsequently hardens to complete the process.

Title: Appareil pour mesurer la hauteur, a partir d'un plancher, du chargement d'un bateau, au travers de marchandises interposees
IPC: G01B7/00
Filed: 1977-09-12
Abstract: L'invention concerne un appareillage pour mesurer une distance à partir du plancher magnétiquement perméable de la cale de cargaison d un bateau. Cet appareil comprend une antenne d'émission créant un champ magnétique bipolaire et une antenne d'émission sensible à ce champ. Les antennes sont éloignées, parallèlement au plancher, d'une distance d, l'axe du champ d'une antenne étant parallèle à ce plancher et celui de l'autre, coupant perpendiculairement cet axe, étant pratiquement perpendiculaire au plancher. La déformation du champ magnétique créée par le plancher se traduit, dans l'antenne réceptrice, par un signal qui est converti, dans un convertisseur logarithmique, en un signal proportionnel à la distance D entre l'antenne et le plancher, D étant du même ordre de grandeur que d.
