Patent FR-2291461-A1 (FR)
Title: Solar energy water storage heater - has insulated wall mounted vessel and circulation only to replace drawn-off water
IPC: F24J2/04
Filed: 1974-11-15
Abstract: The heater has no moving parts of controls, and it and the reservoir form a single simple vessel enclosed in an insulating casing (3) water circulation being initiated by consumption. The vessel is thin enough for good penetration of the rays, but not laminated, so as to give good convection, so that temperature are kept uniform between two demands for water. It can be thin enough to mount in a wall (2) below a window etc. The effect of shadows on the working surface can be counteracted by ray reflection from the walls of the opening.

Title: Hydraulic turbine blade control assembly - applies opposite blade rotation forces by rotary gate ring and servo motors to reduce vibrations (BR310876)
Inventor: CASACCI SEVERIN
IPC: F03B3/18
Filed: 1975-02-07
Abstract: A hydraulic turbine blade control assembly has one(7) of each pair of blade pivot shafts (7, 8) connected by a lever and link with a gate ring(2), the rotation of which is controlled by the servo- motors (4) and (5) with supply pipes (9) and return pipes (10). Each lower shaft (8) is actuated by the servo-motor (3) with supply pipes (11) and return pipes (12). The resultant couple on each blade (1) is the difference between the couples applied by the two sets of servo-motors. Because there is a force acting on both shafts (7), (8) play in the pivots is eliminated with a consequent reduction in blade vibration. Shear pins (6) prevents any overload being transmitted to the blades.

Title: Car seat with vertical adjustment - has cam plate to pivot between fixed vertical guides to raise and tip seat (BE130976)
Inventor: PEZIER YVES
IPC: B60N2/16
Filed: 1975-03-12
Abstract: The car seat is mounted on a special mounting comprising two fixed vertical supports on the car floor and with the seat linked to the inside faces of the support by a special clamping cam (41). The clamping cam has gear teeth (42) at either end, to engage teeth on the vertical faces of the vertical supports. Pressure faces, operated in conjunction with a hand control lever push against either face to disengage the cam at that end and to tilt it either up or down. This causes the seat to pivot about a horizontal transverse axis on the other end of the cam. Repeated operation of the cam on either side tilts the seat forward or backwards about either axis, or raises and lowers the seat in discrete steps.

Title: Contour determination method for fragile objects - utilises simultaneous photographic recording of light and shade on object
IPC: G01C11/00
Filed: 1975-03-20
Abstract: Photographic recording of light and shade is employed to obtain the shape and dimensions of contours of an inaccessible object at a distance. This technique is used where moulding or mathematical determination is not possible on fragile or original objects. The shape and dimensions of a large object (10) are obtained by photographing (P1, P2) simultaneously areas of light and shade on the object when light is projected (70) onto it. The cameras (P1, P2) and light projector (70) are mounted on a carriage (72) which moves uniformly in a direction (74) perpendicular to the projection plane. The cameras are mounted equidistant from the object and photograph at a plane of projection (76) separating light and shade. The photographs are superimposed to reproduce the object for modelling.

The central trough (4), or point of the M, can be above the base or in contact with it, both giving good crushing resistance. At the point (5), holes (6) are pierced along the pipe length, this area being enlarged to contain a wick (8) of rot-proof material. The remainder of the trough is filled with sand (9). End caps. connectors, crosses and tees are provided. The system is buried in the ground and fed with water at intervals.

Abstract: Between the wood components (1) to be assembled, junction plates (3), having on their two faces spikes arranged in a rosette pattern, are inserted, the length of the spikes being preferably greater than the minimum thickness of the wood components. Pressure is then applied to the latter to force the spikes into them. The alternate spikes extend in opposite directions, and they are formed by pressing out triangular segments of a circle from a plate blank.

The arches (10) of the brackets are of flexible material, both supporting the apron and holding it taut. Where the apron is in the form of a net (7) the upper and lower ends of this can be formed by bolt-ropes (6) with rings (5) sliding on horizontal bars (4,8). The net ends are secured by rings engaging with the ends of the bars. The bracket arches can be of polyester resin reinforced with glass fibre.
Patent FR-2346979-A1 (FR)
IPC: A23B4/00
Filed: 1976-04-06
Abstract: The apparatus is composed of a chest (33) as well as of a leaktight bell (36) with a semi-cylindrical vault (45) and faces (46), which may be closed over moulds which are filled with blended ham and carried by a roller conveyor (35). The edges of the bell are equipped with the seal (52) closing the inner volume hermetically. The lowering of the bell (36) over the chest (33) is damped. Once the apparatus is closed, a vacuum pump is put into operation until the desired vacuum is obtained, and then a circuit commands the automatic re-opening of the bell after a specific period of time. The degassing apparatus operates virtually entirely automatically and can be integrated into a moulding line comprising conveyors for transferring the moulds filled with hams.

Title: Synchronising mechanism for automobile gearbox - has sliding sleeve connected to synchronising rings at low speed (SW 12.12.77)
IPC: F16H61/16
Filed: 1976-05-17
Abstract: The constant mesh gears (2, 3) of an automobile gear box are mounted on needle roller bearings in the shaft (1). Either gear (2, 3) can be rotationally connected to the shaft (1) by sliding the internally toothed sleeve (5) which engages teeth on the inner ring (4) and the dogs (8 or 9) of the required gear wheel (2 or 3). To facilitate engagement at low speeds the synchronising rings (6) and (7) are provided with teeth that engage sliding weights (14). These sliding weights slide in slots in the sleeve (5) and at low speeds fall towards the centre and engage slots in the rings (6, 7). At high speeds when synchronisation is not required the weights move outwards and release the ring (6, 7).

Title: Raw cement flour prepn. - with analysis after grinding controlling additive input to crusher
IPC: C04B7/38
Filed: 1977-06-27
Abstract: Raw cement flour is prepd. from raw mineral and additives, added in the crusher and ground directly into flour which is formed into a heap large enough for a week's run in the factory, so as to adjust the compsn. chemically for homogeneity. The flour leaving the grinder is sampled and analysed from time to time so that the compsn. can be adjusted by altering the scheme of additives at the crusher and opt. at the entrance to the grinder. The formation of the heap is stopped when its average compsn. corresponds to that required, and a new heap is started. Improved homogeneity or product is achieved.

Title: Solar energy collector - comprising absorbent elements connected in parallel between heat transfer fluid mains arranged within case for max. efficiency
IPC: F24S10/75
Filed: 1977-07-08
Abstract: Solar energy collector comprises a rectangular case with a face exposed to the sun closed by a transparent plate, contg. absorbent elements in which a heat transfer fluid circulates, and which are connected in parallel between a cold and hot mains are placed in the case. The heat transfer fluid circulates in the same sense in the two sections of the two mains between which the absorbent elements are connected. The two sections are situated along two opposite sides of the case. The collector is principally for absorbing solar energy, but it may be used to collect other forms of energy, e.g. from a well-insulated building, and it may operated by absorbing radiation, by conduction and by convection. The length or width can be varied by varying the number of modules and their length while retaining equal flow distribution between the elements so that efficiency is increased. The arrangement of the internal structure gives increased useful absorbing surface and minimises loss of heat through the side walls and cooling of the liq. circulating in the hot main.
