Title: Live body cell ionisation appts. - has pairs of electrodes constructed to provide positive and negative energy respectively
IPC: A61N1/20
Filed: 1976-04-12
Abstract: The apparatus ionises the cells of a live body, generating itself the energy for ionisation. It has a set of four electrodes, each with one or more components of conductive metal, while two of them also have a component of spongy material which can be impregnated with any suitable liquid. The conductive metal components of each of the electrodes have an electrical potential such that the combined use of two generates positive energy, and that of the two others negative energy. Two of the electrodes can each comprise a single component of conductive metal.

Title: Seagoing oil rig support structure and deck - constructed by floating the fully equipped deck onto the submerged support structure before towing into position (NO 14.12.77)
Inventor: LAMY JACQUES-EDOUARD JEAN
IPC: E02B17/02
Filed: 1976-05-20
Abstract: The deck is constructed in the form of a water-tight hull so that it floats and comprises >=2 separate pieces which are assembled after positioning on the support structure. The rig is assembled by immersing the support structure to a depth such that the part to which the deck will be fixed is level with the deck. After being fixed the platform is floated up again, when it can be towed out to its installation site. It allows the mounting of a prefabricated deck constructed in either concrete or steel. The method of assembly eliminates the use of barges or cranes when placing the deck on the support structure. Mounting of the deck with most, or in some cases all, of its equipment in place, is possible. It reduces the delay normally experienced in mounting the deck and its equipment. Security of the platform during assembly is increased. In facilitating the construction, the cost is reduced.

Title: Fibrous filter - operating with surface filtration on a circulating fluid e.g. cutting oil to maintain a low conc. of microorganisms as well as solids
IPC: B01D35/157
Filed: 1976-06-10
Abstract: Filter containing a mass of fibres with fluid inlet and fluid outlet surfaces a boundary to a fluid inlet and fluid outlet chamber respectively, so formed that it accepts the flow of the fluid from the fluid inlet to the fluid outlet chamber. These chambers are additionally interconnected by a draw-off element so constructed that it carries a part of the fluid flow from the inlet chamber directly into the outlet chamber. The part flow passes along the fluid inflow and out-flow surfaces of the fibre mass, resulting in a surface filtration in contact with these surfaces. Pref. the fibres are cellulose, cotton, viscose, rayon, polyamided, polypropylene, glass, SiO2, aluminosilicate, asbestos, or metal oxide, esp. polycrystalline ZrO2, Al2O3 or Al2O3/SiO2. The utilisation of surface filtration enables satisfactory filtration and removal of growing microorganisms to be continued for extended periods even where, as in a cutting oil, additional solids must also be removed.

The window (3) is formed in the top of the housing (2), and is equipped with a shutter (5) adjusting the area of the window left free for the passage of light. In addition, a three-position switch (8) cuts off the current to the light source, or causes it to function at two different levels of intensity. Removable feet on one of the large vertical walls of the housing allow it to be hooked in position on a wall or partition.

Title: Continuous measurement system for fluid flow - utilises chamber with outlet controlled by pivoting paddle and pressure differences
IPC: G01F1/28
Filed: 1976-08-12
Abstract: A flow meter provides continuous and instanteous measurement of fluid flow. The fluid passes through a chamber whose outlet is controlled by a pivoting paddle and by upstream and downstream pressure differences. Two annular chambers (2, 3) are separated by a section (4) containing several calibrated holes (18). One chamber (3) contains a pivoting paddle on a central head (14) forming a dynamic control compartment which communicates with the upstream compartment (8) in the other chamber through a window (17) while a static resistance chamber (16) communicates with a downstream compartment (10) via calibrated holes. Pressure differences are applied to the paddle opposing spring (25) action to obtain balace. Angular position of the paddle is indicated on a dial (30).

Patent FR-2375556-A1 (FR)
Title: Solar energy heater for mounting on vertical walls - having asymmetrical, multicoloured projections to absorb the sun's heat
IPC: F24S10/55
Filed: 1976-12-23
Abstract: It has as flat wall at the back, and the front, heat absorbing wall as many assymetrical projections. The distance between the two walls may vary depending of the vol. of hot water required. The water circulates between the two plates, entering by a tube at the base and leaving through a tube at the top. A shutter can be closed over the front absorbant face at night to prevent heat loss. The solar heater can be placed vertically on a wall and is easy to make. By varying the colour of the faces of the projections, the dark, sombre aspect of the front face of the heater can be avoided, thus making it more acceptable on a building wall.

Title: Thyristor a electrode de court-circuit d'emetteur pour commande de commutation a tension nulle
Inventor: HEINECKE RUDOLF AUGUST HERBERT
IPC: H01L31/16
Filed: 1977-02-25
Abstract: Thyristor de puissance dont la couche de commande de type P comporte des régions de surface 21 traversant la couche cathodique N**+. Selon l'invention, les régions 21 sont isolées de la cathode par des gorges circulaires 12 analogues à celle il qui isole le contact de gâchette et elles sont reliées à une quatrième électrode (émetteur). Le court-circuit émetteur-cathode peut ainsi être contrôlé par un commutateur électronique extérieur, par exemple un transistor. Pour un signal de gâchette d'amplitude définie, le thyristor ne peut être amorcé tant que le court-circuit est fermé ce qui permet de réaliser un circuit de commande de commutation à tension nulle extrêmement simplifié. Application particulière aux photothyristors pour relais statiques à isolement optique des circuits de commande et de puissance.

Patent FR-2357735-A1 (FR)
IPC: F02F7/00
Filed: 1977-07-01
Abstract: The oil sump (12) is provided with an outer flange (10), on which a rubber-elastic profile section (14), closed over the circumference of the flange, is slid. This profile section serves for sealing and centring of the oil sump (12) in an oil sump frame (5) and for isolating the structure-borne noise of the crank case (1) from the oil sump (12). The metal parts adjacent to the profile section (14) partially enclose this in order to largely protect it against the hot oil and against mechanical damage. The profile section (14) presents different degrees of stiffness in different directions in order to improve sealing and the isolation of structure-borne noise. The profile cross section comprises two hollow bodies, for example rings, connected by a bridge. The profile section (14) presents different degrees of stiffness especially in two planes perpendicular to one another.
