Patent FR-2706997-A1 (FR)
Title: Device for protecting an armoured structure from high energy projectiles
IPC: F41H5/007
Filed: 1975-03-18
Abstract: The structure to be protected comprises main armour 1 and auxiliary armour 2 spaced from the first one on the side to be protected. On the side facing the main armour 1, the auxiliary armour 2 comprises acceleration means, consisting for example of an explosive layer 3 provided with a metal coating 4. The acceleration means can be triggered by the arrival of a projectile in order to project the auxiliary armour 2 towards the main armour 1. The projection velocity reduces the relative impact velocity of the projectile on the auxiliary armour 2. Application to armoured structures, particularly for the protection of armoured vehicles.

Title: Async. motor with cage rotor - has water cooled stator and air cooled rotor enabling higher power operation
IPC: H02K9/16
Filed: 1976-04-21
Abstract: The async. motor has its stator cooled by water and its rotor by air in such a way that greater power is attained and performance is relatively constant over long periods of time. The cooling channels in the stator or in the rotor carry air out in opposite directions. The ends of the stator's cooling channels or the pressure rings of the rotor are arranged such that the cooling channels (at the level of their two extremities) open alternately into free space or into the space enclosing the winding overhang at the front of the motor. It is not necessary that both the stator and the rotor having cooling channels one or the other is sufficient.

Title: Speed control unit for induction motor - provides two out-of-phase variable frequency voltages for two or three phase windings
Inventor: BREGEAULT MARC
IPC: H02M7/538
Filed: 1976-06-15
Abstract: A speed control unit for two-phase or three-phase induction motor can be used in ventilation equipment. It provides two out-of-phase variable frequency voltages and does not need the use of a compensating capacitor at the motor. The unit operates from a voltage (V1) which can be varied. It has a sub-unit (2) which transforms the input voltage (V1) into another voltage (V2). The second voltage (V2) varies linearly with time. Another sub-unit (3) generates two voltages (Va1, Va2) can be set by the amplitude of the first voltage. Two power amplifiers (4, 5) are used to give two control voltages (V4 V5) for the motor.

Title: Colour phase correction in SECAM system TV receiver - has switching circuit with two comparators and gating circuits
IPC: H04N9/70
Filed: 1976-07-01
Abstract: In the SECAM television system a receiver colour demodulator employs a control circuit to adjust a switching circuit to produce a correct phase output. By using two comparators at the output of the colour identification signal integrator improved operation of the switching circuit is achieved. A demodulator and phase correction control circuit contains a switching circuit controlling demodulator operation and whose colour identification signal is integrated. The integrator output is applied to level comparators with reference voltages. Depending on the colour identification signal their logic output signals are applied to gates with a signal obtained from the vertical synch. signal. Gate output signals are applied to a flip flop to ensure the colour blocking circuits in the demodulators are in the correct phase.

Patent FR-2320175-A1 (FR)
Title: Extrusion nozzle for thin coatings on carrier bands - has bottom front edge designed to act as doctor
IPC: B29C48/07
Filed: 1976-08-06
Abstract: An extrusion nozzle for coating a band of carrier material with a plastic mass, comprises a hollow body extending across the full width of the carrier material. Fittings are attached for feeding and recycling the plastic mass through the extruder body, the bottom from edge of which is designed to act as a doctor. The distance at which the doctor is positioned from the carrier determines the width of the outlet slot of the nozzle, which is located so that the hollow cavity of the extruder noxxle is enclosed by its side walls. Coatings of magnetic dispersions less than two millimicrons thick for recording tapes, can be produced without difficulty. The forces necessary to hold the extruder down can be reduced considerably, so that much greater variations in pressure in the flow can be tolerated.

Title: Mixing pump blending two liquids in required proportions - utilises pistons in variable volume chambers to control auxiliary liq. supply
IPC: B07C5/34
Filed: 1976-08-13
Abstract: An auxiliary liquid which is mixed with another liquid such as water is required to be in specific proportions. This is effected by a water counter comprising two pairs of chambers with variable volumes which also ensure correct dosage of the auxiliary liquid. A counter comprises two cylinders (1a, b) in which pistons (2a, b) form two variable volume chambers (3a, 3a', 3b, 3'b). A shaft (4b) ensures operation in synchronism. Each chamber communicates with an inlet pipe through an orifice and via spring loaded valves. Each chamber communicates with an outlet pipe through an orifice (11) and spring (14) loaded valves (12). As the pistons move the chamber contents are alternately emptied while operating a piston (2b, b) in cylinders (27b) connected to inlet values (28) for auxiliary liquid.

Title: Coal pick with integral securing ring - has shoulder on stem part matching shoulder inside hole in holder
Inventor: WETZCHEWALD KARL HEINZ
IPC: E21C35/18
Filed: 1976-09-07
Abstract: A coal pick (3) for a mining machine is secured in a holder (1) which has a hole (2) to receive the stem of the pick, having a shoulder (4) port of the way down. This gives a larger diameter mount for the hole. The pick carries a securing ring (6) around its stem, underneath the enlarged head. The stem is also stepped, having a shoulder (5) matching the shoulder (4) of the hole. The stem of the pick is larger above this shoulder, thus matching the shape of the hole. In an alternative design there is a shoulder immediately under the head, instead of on the stem, and there are no matching shoulders inside the hole.
