Title: Automobile engine with four cylinders in V - has reversible dynamo forming brake or motor and charging or discharging battery
IPC: B60K6/24
Filed: 1974-06-05
Abstract: The engine has a reversible electrical generator which can act as a brake or as a motor, to charge or dicharge a battery of accumulators. In combination with the reversible generator is reversible control switch. The object of the system is to save fuel by regaining energy normally absorbed by the brakes when going down hill or when stopping and by reducing engine fuel consumption at low loads. The engine crankshaft runs in roller bearings as do the connecting rod big ends. This reduces friction and so fuel consumption.

Title: Anti locking vehicle braking system - monitors wheel speed and corrects that brake pressure up and down
Inventor: KERVAGORET GILBERT
IPC: B60T8/34
Filed: 1974-06-14
Abstract: An anti-skid braking system generates signals of wheel speed and a control signal relative to the risk of wheel locking on brake application. It then closes the fluid source to the affected wheel brake and modulates the pressure in this brake when the signal is received and compares pressures between the master and brake cylinder and adjusts pressures accordingly. The modulator is a valve receiving master cylinder pressure via an orifice (136) to a chamber with a spring (138) and ball (136) and piston (137) arrangement, the far side leading to the brake cylinder (114). Below the ball is a rod (146) controlled in movement by an electromagnet (164) and ball valve (142) in association with other fluid passages (130, 147, 132) and a spring diaphragm re-feed device (270).

In one embodiment, Fig. 1, a fixed metallic shaft 14 is trapped between the parts 10, 12 which are provided with a seating to receive the shaft 14. The parts 10, 12 are caused to undergo alternating motion relative to one another along a line D. In a modification, Fig. 2 (not shown), a shaft (18) is trapped between the parts and is formed with splines or is of non- circular cross-section so as to slide between the parts but not rotate about its own axis. In another embodiment, Fig. 3, the object 22 comprises a shaft with a circumferential groove therein so that, after welding, it is held against longitudinal displacement but is able to rotate. In a modification, Fig. 4 (not shown), the object (24) is longitudinally splined and has a circumferential groove therein to prevent movement in any direction. In a further embodiment, Fig. 5, a grid 26 is trapped between the parts 10, 12. The alternating motion between the parts 10, 12 may be linear (arrow D 1 ) or angular (arrow D 2 ). Thermoplastic material flows between the orifices of the grid. In a modification, Fig. 6 (not shown), a metallic braided element (28) is trapped between the parts. In yet another embodiment, Fig. 7 (not shown), a rubber diaphragm (30) is trapped between the parts. For small objects, no initial seating is provided in the parts 10, 12. Prior to inserting the object, it may be momentarily heated, e.g. by the passage of electric current therethrough.

Title: Anchovy cream for preservation in tubes - is prepd. by mixing salted and fresh anchovies and sterilising
IPC: A23L17/00
Filed: 1974-11-08
Abstract: Anchovy cream, for preservation in tubes, is made by mixing salted anchovies with fresh or frozen anchovies, pounding the mixt. and filtering it, after the addition of vegetable oil and food seasonings; the treated mixt. is introduced into tubes which are then sealed to undergo a heat treatment accompanied by a counter pressure to prevent their deformation during this heat-sterilisation. The tubes are enamelled before filling; they are afterwards packed and distributed inthe usual manner. The cream is part. homogeneous; it maintains this homogeneity for a long time. The paste is generally more plastic and pliable than pastes made hitherto because the addn. of fresh anchovies provides fibres which confer a certain structure. The vegetable oil can be olive oil and the seasonings may contain spices. The addn. of fresh or frozen anchovies to the salted and matured anchovies noticeably smooths the cream by reducing the % of salt.

Title: Book cover with rigid and flexible sheets bonded together - with hinge line formed by weld of modified thickness between sheets
IPC: B42C7/00
Filed: 1975-12-17
Abstract: Bookbinding cover is mfd. by bonding together two sheets one rigid and one flexible, then forming >=1 hinge line between the flat covers and spine of the binding in the form of a weld between the sheets. The thickness of the rigid sheet is greatly reduced in the weld, while that of the flexible sheet is maintained. Pref. the sheets are made of synthetic plastic materials, and the weld is formed by localised application of electric currents, both to join the edges of the sheets together and to form the hinge line. This method economically combines the rigidity of the sheet forming the flat covers and spine, with optimum flexibility for the hinges between the flat covers and the spine.

Patent FR-2350873-A1 (FR)
IPC: F04B7/04
Filed: 1977-01-07
Abstract: The appliance has an improved dosing accuracy, to dispense chemicals into a line carrying flowing water. The appliance furthermore is self-venting, self-priming, safe to run dry, and self-flushing. To this end, a chamber (21) having a flexible wall section (28) is arranged in the connecting line from the pump discharge side to the water line (17). The flexible wall section (28) delimits an air volume, which is small compared with the chamber (21), in a side chamber (30). Said air volume prevents, by causing the flexible wall section (28) to bulge, any pressure fluctuation in the chamber (21) as a result of the pump motion.
