Title: Low temp. refuse carbonisation drum - with hollow ribs for heating gas circulation and charge mixing
Inventor: KIENER KARL DIPL ING
IPC: C10B1/10
Filed: 1977-03-24
Abstract: A low-temp. carbonisation drum for rubbish such as domestic and industrial wastes, worn tyres or plastic scrap, has hollow tooth-like ribs on the inside of the horizontal drum which form the passages for the counter flow of the heating gases. At the refuse charging end the heating gases are collected and returned by a blower to the discharge end where additional burners may be used. The ribs assist in the thorough mixing of the charged rubbish and provide a greatly increased heating surface. The heat input can be controlled within wide limits.

Title: Power cylinder distributor block - has differential piston controlled by three identical integral flow control valves with equalising operation
Inventor: STUMPMEIER FRITZ ING GRAD
IPC: F15B13/08
Filed: 1977-04-25
Abstract: The distributor block is used to control a set of power cylinders having different piston areas. The valve belonging to the larger piston area can be adjusted optionally to the piston area of the power cylinder connected to it, without influencing the operation of the other valves built into the block in module fashion. Each power cylinder is controlled by four two-way valves (PA, PB, AT, BT). The valves (PA1, 2, 3) pressurise the load of the piston areas (A) and the valves (PB1, 2, 3) load the piston areas (B). A pump (12) is connected to channels (13) in the block. The fluid displaced from the cylinders (1, 2, 3) flows through channels (14), distributing valves (AT1, 2, 3) and (BT1, 2, 3) into a tank (15). The distributing valves of each cylinder side are interconnected by distributing elements (16) fitted in lateral channels.

Title: Electrical cable extrusion monitor - surrounds cable with resistance probe whose length varies with cable diameter
Inventor: GOEHLICH LOTHAR ING GRAD
IPC: G01B7/06
Filed: 1977-06-28
Abstract: A measuring jig surrounds a cable (8) and has a number of probe arms (10) which bear on the surface of the cable. Each probe arm has a hinged parallelogram mount (16) so that it tracks substantially parallel to the cable sheath and carries a roller (11) to reduce frictional resistance between the cable and the measuring jig. A measuring resistance wire (20) is held in tension by means of a spring (23) and is fed by way of pulleys (21, 22) to guide rollers (18), one of which is mounted on each probe arm with its axis parallel to that of the cable. The resistance wire surrounds the cable completely and electrical contact is made at two points. As the cable dia. varies during extrusion, so the length of resistance wire between the two contacts alters. The change is measured resistance provides a means of monitoring the cable diameter.

Title: Solar energy plant including cells supplying circulating pump - to protect against overheating and ensure economic operation
Inventor: SCHOEN KURT DIPL ING
IPC: F24J2/40
Filed: 1977-12-10
Abstract: A heating installation utilising the energy of the sun is protected not simply against uneconomic operation when the temp. at the collector is lower than that in the storage vessel, but also protects the collector itself against damage by overheating in the event of a power failure to the pump. Beside the collectors, solar cell(s) are provided and are connected to the pump motor. This is partic. advantageous since precisely when overheating could cause damage, the output of the solar cells would be at its maximum.

Title: Continuous casting plant with upward extn. of prods. e.g. tubes - using set of rolls followed by flying shear and manipulator transferring prods. to down moving endless conveyor
Inventor: ZABAVA JURIJ G
IPC: B22D11/126
Filed: 1978-03-07
Abstract: The plant has >=2 chill moulds for the simultaneous casting of >=2 prods., e.g. tubes. Above each mould is a set of extn. rolls lifting the casting out of the mould, and driven by couplings and pairs of worm drives so the cast tube can only move upwards. Above the set of extn. rolls is a flying shear in a housing travelling on vertical guides in synchronisation with the cast tube so he latter is cut to length while moving upwards. The cut length of tube is then gripped by a manipulator, which swings the tube from its vertical position into a horizontal position, so it rolls down a chute and into a through mounted on an endless conveyor belt. The belt is fitted with an endless row of troughs used to lower the cut lengths of tube into a storage bin.
