Patent FR-2294579-A1 (FR)
Title: Perpetual motion electricity generator - repulsion between magnets causes reciprocation resulting in current in coil
IPC: H02K53/00
Filed: 1974-12-09
Abstract: A generator operating with perpetual motion consists of a cylindrical mobile perm. magnet which rolls along a circular guided track down a slope until it meets another fixed permanent magnet which repels it. The repelling force is sufficient to bring the cylindrical magnet from this point back to its starting point from where it goes back down the slope repeating the cycle and thus creating a perpetual motion. The changing flux created by the motion of this magnet induces a voltage in a coil thereby producing electrical energy in the coil.

Title: Two-compartment bottle for two-component pharmaceutical prods. - which must be kept apart until the moment of injection
IPC: B65D81/32
Filed: 1974-12-18
Abstract: Two-compartment bottle is intended for pharmaceutical and veterinary prods. for use with substances which react with each other and must only be mixed immediately before injection. The bottle is made from two parts (1,2); part (2) is made from a plastic material while part (1) is made from glass. The base of part (2) consists of a membrane which separates the two compartments thus formed. One compartment is closed by a stopper which is fitted with a punch with its cutting blade near the membrane; this compartment holds the active powder, while the liq. is contained in the other compartment. The two are mixed by removing a safety ring and forcing the stopper downwards; the punch cuts the membrane and the powder falls into the liq. The mixt. is withdrawn by pushing the syringe needle through a rubber plug. Either of the two compartments may be chosen to hold the solid, although the upper is more usual. The mixt. is not prepd. until immediately before the injection.

Title: Microbiological diagnosis equipment for detecting pathogenic germs - contg. nutrient media test combination for analysing bacterial gps.
IPC: C12Q1/04
Filed: 1975-02-14
Abstract: Tissue samples are prepd by embedding in paraffin etc for microtome sections required for histological research by passing them in turn through dehydration, stabilisation and impregnation baths, arranged in a circle. The baskets carrying the samples are suspended from a rotatable spider and are lowered into the respective baths in turn by program control. This allows successive prepn of the tissue samples in charges as they become available in hospitals or research laboratories. Urgent samples can be treated faster and labour available is better utilised.

Title: Roller bellows for pneumatic cushioning - have fibrous layers with airtight bed preventing shifting of drive assemblies
Inventor: FARKAS OTTO
IPC: F16J3/06
Filed: 1975-04-18
Abstract: The roller bellows are for pneumatic cushioning, and are of a fibrous layered material with two plies. The two layers lie between the cover plate and the airtight bed. Under minimum load, the bellows are not crushed and have maximum radius of curvature. In this condition the bellows becomes smooth and maintains the seal and the angle. The air cushioning system lessens the possibility of sudden shifting of the drive assemblies of vehicles. Horizontal movement and slight changes of alignment are, however, not prevented. The space occupied can be greatly reduced, and the installation can also be lowered and raised.

Title: Combined overflow and plug fitting for bath - has plug which is lifted by tensioning deflected cable via winding drum at overflow
IPC: E03C1/232
Filed: 1975-12-04
Abstract: The combined overflow (2) and plugged (11) outlet (1) fitting for bath or shower includes a vertically reciprocating plug (11) which is lifted by a traction cable (7). The cable (7) is tensioned by a winding drum (17) and manually rotatable wheel (15) incorporated in the overflow outlet fitting (2). When untensioned the cable (7) is deflected by the plug (11), straightens upon tensioning, and thus lifts the plug (11) off its seat to open the outlet orifice. The cable (7) is guided in a pipe (4, 5) which connects the overflow outlet to the bath outlet pipe at the plug casing. An eyelet and a diametrically opposed sleeve (8) may be incorporated in the plug casing (1) to anchor and guide the cable (7) beneath the plug. The drum axle (18) may bear on a rubber disc (22) to provide a limited resistance to rotation and thus hold the plug in the open position.

Title: Switching circuit for programming facility for ECL ROM - has line selection circuits which allow setting voltage level to be applied for programming memory cells
IPC: G11C17/16
Filed: 1976-02-04
Abstract: A switching circuit provides a means of programming an ECL ROM. Each memory cell (SMA) in the matrix consists of a transistor (ST) and a fused resistance (RS). The memory cells are coupled to input lines (ZL) and output columns (SL). Address signals (Ao-A7) select the required lines and columns over address amplifiers (ADV1, ADV2). For the columns the amplifiers are coupled to a decoding circuit (DS) operating into four groups of switching stages (S5) and generating outputs to amplifiers (LV) during the read cycle.

Title: Printed coil on insulating board - has spiral turns of variable width increasing outwards (BR091176)
Inventor: HAAS DIETER
IPC: H01F27/28
Filed: 1976-05-10
Abstract: The coil is printed on an insulating plate and has a number of helical turns which are of different width. According to the requirements the width of the printed turns is smaller on the inner turn than on the outer ones, or the width may be reduced from the outer turns to the inner ones. Alternately part of the turns may be smaller width than another part of the coil. The width reduction in the coil part with the smaller width may be located between the coil terminals, where the turns run along a straight line. The design of the printed coil reduces the space requirements, while safeguarding a given quality with a maximum inductance.

Title: Printing rollers for applying multicolour designs to plastic film - film passing over successive rollers each transferring ink of different colour
Inventor: DOHERTY THOMAS HENRY
IPC: B44C1/04
Filed: 1976-06-18
Abstract: The multi-colour printing of designs on coating cloth and unsupported film made of plastic material involves the production of disordered designs of different format. Each of these is developed on a corresponding printing cylinder by, for example, an engraving technique. Cylinders of different diameter may be employed and the plastic film itself may be coloured, mulit-coloured or carry a definite recognisable pattern. A Light-transmitting ink of the required colour is applied to each cylinder and relative movement between the cylinder and the ink is created while the two are in contact. As the film passes over the various cylinders the required multi-colour design is built up from the various layers of different coloured inks which have been applied.

The interior is thus kept at excess pressure or under pressure. There may be two cavities in the wall between the outer and inner casings, so that the air first circulates in the first cavity, and then in the second before being discharged outside.
