Patent FR-2293851-A1 (FR)
Title: Stacked diode and rectifier circuit with circuit boards - has beginning sections of conductive tracks forming terminals accessible near board edges
IPC: H05K3/36
Filed: 1975-11-28
Abstract: The conductive tracks of the circuits are provided on two circuit boards sandwiching an insulating securing plate, whose apertures retain diode elements for discrete contacting. The tracks (L1, L2) of the circuit boards (1, 2) are produced by etching or printing and the conductor beginnings (A1, A2) form connecting terminals, freely accessible near the circuit board edges. The conductive tracks have multiple interruptions and branching over a part of their length. All conductive tracks forming contacting points at their ends (E1, E2). The contacting points are aligned not only on both circuit boards, but also with the diodes (D) held in the apertures (B) of the intermediate fastening plate (3).

Title: Liquids to replace water as turbine driving fluid - of specified physical constants esp. pentachloroethane
IPC: F01D25/00
Filed: 1976-02-23
Abstract: A process using driving fluids with a low heat of vaporisation, such as are required to drive a turbine for example, comprises using, instead of water, a liq. of boiling point 125-200 degrees C specifically pentachloroethane. The liqs. are used in turbines and other motors which are driven by steam. The use of the liqs. to replace water increases the thermodynamic yield, which is the case of steam turbines is very low, (about 35%), because of the high heat of vaporisation of water (537 Mth) and specific heat (1) which result in heat loss in the condensation system.

Abstract: The heating device employing positive temperature coefficient semiconductor (PTCS) heating elements comprises the PTCS heating element (2), upper and lower insulating plates (3,4), a heat emission plate (5) and a case (6) for entirely covering the layers of the PTCS heating element and the upper and lower insulating plates. The device produces heat from the emission plate, the heat being evenly distributed over the plate. The PTCS element is not readily disengaged by a shock to the device, which is simply constructed for ease of manufacture.
Patent FR-2310460-A1 (FR)
IPC: E05D15/52
Filed: 1976-05-04
Abstract: In two-wing windows or doors without a setting wedge, a flush bolt is arranged in the rebate of the lower wing, in order to secure this wing against the fixed frame even when the upper wing is opened. In the flush bolt (11), the drive of the bolt rod (14) takes place in a largely play-free manner via an eccentric (34) mounted in the long hole (35) of the bolt rod. The eccentric is arranged on the pivot axis of the pivoting lever (28), which pivot axis is perpendicular to the baseplate (17) of the housing (16) of the flush bolt. By means of the eccentric drive of the bolt rod (14), a positive drive of the bolt rod takes place, along with a reduced constructional height of the flush bolt. In addition, with the upper wing tilted, unauthorized actuation of the flush bolt from outside is prevented, since the pivoting lever is restricted in its pivoting possibility by the overhang of the tilted wing.

Title: Sorter for small nuclear fuel spheres - uses rotatable perforated disc and low pressure suction
IPC: B65G47/14
Filed: 1976-06-04
Abstract: The appliance sorts small spherical nuclear fuel elements of different sizes, density, and roundness. The elements are sucked up by a rotating disc with a ring of perforations of smaller diameter than the particles, and a pneumatic pressure differential across the disc. Adhering particles are removed by a gas jet. The pressure differential is removed, and by blowing from the opposite side of the disc, the elements are ejected individually. The disc (2) rotates beside a blow nozzle. A gas pressure tube (5) leads through that chamber, and ends on the disc opposite to the element ejection channel (6).

Inventor: ZWEIGLE DIETER
IPC: G01G17/02
Filed: 1976-09-29
Abstract: A balance consits of a measuring appts. fitted in a balance assembly and presenting and oscillating system comprising (i) a mechanically operating pulse generator, which undder the influence of a load, can be displaced, for the determn. of the true wt. of the load, from its rest position, at least in the direction of the gravitational force and (ii) a time measuring device by means of which at least the instant at which a sinusoidal damping curve produced by teh oscillating system start can be perceived in order to determine the wt. The pulse generator has a part capable of oscillation and of receiving the load which rests on a support displaceable in the direction of oscillation, which for the determn. of the true wt. can be displaced at a constant speed. The time which has elapsed during the descending motion of the support from a fixed starting point to at least the sepn. of the part capable of oscillation from the support, can be measured by means of the time measuring device intended for the determn. of the wt. The point of release from the support defines the instant of the start of the sinusoidal damping curve, produced by the part of the pulse generator capable of oscillation. The oscillating system is simplified using the adjacent time measuring device as an integral part of the equipment for direct determn. of wt.

Title: Height regulator for hydrofoil - has height sensor signals compared with upper and lower height reference signal and control by fins mounted on foils
Inventor: HIRSCH IRVING ALFRED
IPC: B63B1/28

Title: Porous fabric construction - has groups of warps and weft strands to give an integral separating layer between woven layers
IPC: D03D11/00
Filed: 1977-01-13
Abstract: In weaving a highly porous and open fabric, strands are used as the weft in two groups of planes along the line of warp intersection. The first group is composed of parallel planes under each other th give successive and equidistant levels and lines; the second group is also formed into parallel and equidistant planes under each other to lie on successive ranks or in successive columns. The warps have a group which follow the same path through the wefts. Each warp is displaced from its neighbour by a given number of ranks or columns. The fabric also has a second group of warps associated with at least a fixed number of wefts. The warps in the second group run alternately above and below the successive strands of the various weft columns so that in this line or level an integral separating layer is formed within the scree or screen thickness of the woven fabric. The fabric has a high porosity with some 80% of its structure being empty space, with many applications, particularly in bonding together two incompatible materials as the separating layer insulates against any reaction.
