Title: Filled container vacuum closing machine - has centering system with tapered ring to compress edge of container onto lid
Inventor: LANG HANS-JOERG
IPC: B65B31/02
Filed: 1978-03-07
Abstract: The vacuum closing machine for fitting lids onto containers (7) which have been supplied with a loose lid (8) has a degassing position with a plate (13) which is lifted upwards by a cylinder (9) towards a sealing hood (19). Inside the vacuum chamber under the hood (14) is a piston which moves a block with a magnet in the centre downwards to centre the lid, and secure it initially in the presence of a protective gas. The block operates inside a ring shaped member to act as a reducing device. At the next stage, the top of the container with the lid in position is forced against the sloping interior (37) of another hood (36) so as the crimp inwards the edge of the container onto the lid. The stroke for the operating piston can be varied.

Title: Radio interference signals suppression system - uses auxiliary receiver tuned close to main receiver with signal comparator
Inventor: REHM SIEGFRIED ING GRAD
IPC: H04B1/10
Filed: 1978-03-23
Abstract: The device is used in esp. a recording monitoring radio receiver which performs an automatic search run. It has an auxiliary receiver tuned to an auxiliary frequency (f (+-) delta f) near the monitoring receiver (A) recption frequency (f). A level comparator (5) compares the levels of the two receivers (A, B), and when both signal levels are equal, evaluation of the monitoring receiver (A) output signal is prevented. RAndom noise across a wide frequency spectrum is thus filtered out and only the desired signal on a narrow bandwidth is processed.

Title: Coke wharf ramp - with curved profile on belt conveyor carriage to lift retainer beams for coke transfer
Inventor: NEUMANN HANS
IPC: C10B39/18
Filed: 1978-12-01
Abstract: A coke wharf for coke oven batteries separates the belt conveyor from the inclined ramp by a line of vertical retainer beams. A carriage which travels on rails above the belt is fitted with a bell-shaped curved which lifts the retainer beams by cams attached to them. This creates a passage for the cold coke to slide on the belt as the carriage travels along the conveyor. This ensures a uniform loading of the belt conveyor independent of the intermittent discharge of the coke from the quenching car.

Title: Flexible armouring for power cable - consists of helically wound metal strip bent into interlocking shape forming chambers matching bends
IPC: F16L11/16
Filed: 1979-05-14
Abstract: The power cable for e.g. a machine is protected by a flexible metal armouring which permits the cable to bend easily. This armouring is made from S section metal strip which is wound helically around the cable. Normally, the end (5) of each S section fits against the centre (6) of the next section, with a hollow space (11) between. When the cable bends, each S section slides over the next, reducing the size of the chamber. This chamber can be greater at one end than the other, to match the bend, and can be zero at one end. Alternative sectional shapers include a double bend at one end of the S shape, and various pressings with interlocking portions. The chambers can be filled with a substance such as a hard plastics material.

IPC: B60T13/16
Filed: 1979-06-29
Abstract: A servo assisted master brake cylinder has a floating master piston (10) and a separate input piston (8) linked to the brake pedal. The input piston has a control bore (7) to admit servo fluid to a pressure chamber (30) between the pistons, leaving the other brake circuit as a separate, sealed circuit witbout danger of dust and air affecting the braking. The servo pressure is provided by a pump circuit (P) which feeds a ring groove (24) in the side of the cylinder. In the rest position of the control piston tbis groove is connected to a venting groove (23) back to the pump. A displacement of the input piston shuts off the vent duct and applies the servo pressure progressively to the master piston.
