Title: Armoured plate for preventing penetration by explosives - has bars on its surface with pure tungsten coating
IPC: F41H5/04
Filed: 1976-06-11
Abstract: The low weight armour plate is used for protection against the impact and exothermal effects of an explosive penetrating charge. Metal bars arranged on the armour plate prevent direct impact of the explosive charge and the heat developed is absorbed by metal bars. These bars are covered with high temperature resistant coating which also ensures protection against explosive charges which exert abrasive effect for facilitating penetration. The armour plate is covered with metal bars (7, 8) which prevent direct impact of the explosive charge on the armoured plate. These bars project at right angles from the armoured plate surface which is itself flat, convex or concave. The bars are coated with pure tungsten and they have a base and a head connected by a slender neck section. The bars are spaced closely together and may have different lengths.

Title: Concrete post moulding machine - has hydraulic jack to rotate mould frame in steps with cooling water supplied from rotating tank
IPC: B28B1/20
Filed: 1976-10-18
Abstract: The machine for moulding concrete posts consists of framework mounted on rollers which allow it to rotate about its vertical axis. The frame supports a tank which supplies cooling water to the moulds. The water flows out of the moulds into a tank at the base of the frame. A hydraulic jack rotates the frame in steps so that each mould is brought in turn under the hopper to receive the concrete. Using cooling water speeds up the rate of manufacture of the posts. Supplying this water from the rotating tank eliminates the need to seal rotating shafts.

Title: Electronic anti-theft device for vehicles - uses transistor circuitry and existing electrical system of vehicle
IPC: G08B13/22
Filed: 1977-02-21
Abstract: The electronic anti-theft device for vehicles has an alarm triggered in the event of a break in attempt or theft. A detecting unit is triggered by a fall in battery voltage using a capacitor in parallel with the polarisation resistance of the base of a transistor. A memory circuit holds the resulting signal. This is followed by a first delay, then a power stage controlling a solenoid relay controlling a sounding alarm. Finally a second delay stops the alarm after a preset time. The system may be stopped through an interruptor switch. It is easily fitted into the existing electrical system of a vehicle using e.g. inside light or boot light and the battery. A kaxon or siren is added also in interruptor switch with two additional thin leads which are suitably concealed.
Patent FR-2348288-A1 (FR)
Title: Coiler for draw frame and carding rovings into cans - has calender rollers absorbing centrifugal forces at high speeds
IPC: B65H54/80
Filed: 1977-04-12
Abstract: A rotary mechanism for laying down strands of fibres, esp. draw frame or carding engine rovings, in cans, has a rotating dish and a pair of calender rollers. These are positioned eccentrically to the dish so that the axis of rotation of each roller lies near enough in a plane to which the axis of rotation of the dish is at right angles. The axes of the rollers are arranged at right angles to the line of action of the centrifugal forces acting on the strand of fibres passing through, as the dish rotates, and the axis of the one roller is more-over offset to the axis of the other which lies nearer to the axis of the dish. At the high operating speeds now used, coilers in which the feed rollers are aligned radially to the axis of the dish, are subjected to centrifugal forces tending to throw the roving outwards and cause clogging of the mechanism leading to stoppages. Moreover, in the old design, since the delivery outlet must be vertical, the strand of fibres is diverted twice quite sharply.
