Title: Application of lagging material inside chimney - by feeding material down while vibrating bell is drawn up chimney
Inventor: ROTH PETER
IPC: E04F21/14
Filed: 1979-09-14
Abstract: A lagging material (214) is applied to the interior walls of an old chimney pipe by feeding the material in from the top. A vibrating bell (212) is drawn up the chimney pipe (210) to compress the lining material (214) against the walls to form a solid coating (216).

Patent DE-2941498-A1 (DE)
Title: Gas turbine air compression - has air bled from compressor at part load to maintain turbine efficiency
Inventor: GASPAROVIC NEBOJSA PROF DR ING
IPC: F02C9/18
Filed: 1979-10-11
Abstract: Air is compressed in a compressor driven by the turbine and passed to a combustion chamber in which fuel is burnt. The resulting gases flow through the turbine which drives the compressor and a load. At part load operation some of the air is bled from an intermediate stage of the compressor and discharged to atmosphere. The mass flow through the combustion chamber and turbine is thus reduced at part load. Because of this the temperature at inlet to the turbine remains the same as at full load and the turbine efficiency is maintained at a high level.

Title: Electrolytic cell for sewage disposal - with concentric metal electrodes between plastic base and top cap
Inventor: HRSKA KARL DR
IPC: C02F1/461
Filed: 1979-12-22
Abstract: An electrolytic cell, e.g. for enriching a sewage with a sodium chloride content by a concentration of hypochlorite consists of an inner tube metal anode, surrounded by a concentric outer metal cathode. The two are held together by tie rods between a base plate and a top cap made of insulating material. The sewage enters at the bottom of the annulus, ascends in the annulus, descends in the anode and leaves through a hole in the centre bottom. An automatic degassing device for the hydrogen is arranged at the centre of the top cap and contains a shuttle valve with a plastic ball. This cell combines small overall dimensions with a short retention time. The sewage flow is free from dead end corners and utilizes the entire electrode surface area without dangerous hydrogen accumulations.

Title: Steplessly-adjustable belt transmission unit - has discs moved axially by ramp faces dependent on load
Inventor: KOERNER HELMUT
IPC: F16H9/12
Filed: 1980-01-09
Abstract: The transmission unit has belts working between pairs of discs hydrostatically adjusted in relation to each other in the axial direction, being particularly for a motor vehicle. In opposition to their hydrostatic setting, discs (3,4) axially adjustable in relation to each other on a shaft (1) are moved dependent on the load by the belts (10,11) under the effect of ramp faces in relation to discs on a second shaft. The ramp faces transmit torque as the discs turn in relation to the shaft, adjusting the discs (3-6) axially, and generating pressure between them and the belts to match the load.

Title: Copper tube for plumbing - where one end of tube is widened to form socket, so two or more tubes can be assembled via spigot and socket joints
Inventor: UHLMANN OTTO
IPC: F16L13/08
Filed: 1980-01-16
Abstract: The tubes are 5-10 metres long, and are in the half-hard or hard drawn condition, they may also be provided with a thermally insulating sheath. At least one end of the tubes is expanded to form a socket with a bore dia. slightly larger than the external dia. (o.d.) of the tube. The axial length of the socket is pref. equal to the od. of the tube. The socket is pref. formed by driving a mandrel into the end of the tube, the mandrel is then removed, and the socket is temporarily closed by a polymer plug, esp. a plug made of a foamed polyolefin. The plug may be heated so it fills the socket. For heating or sanitary installations in houses etc., where the socket provides an inexpensive means of joining two pipes and eliminates expensive pipe fittings, the number of soldered or brazed joints is also halved.

Title: Continuous vulcanisation in moving zone - comprises controlling peripheral vulcanising drum speed as a function of zone arc length
Inventor: ARLT GUENTER
IPC: B29C35/02
Filed: 1980-06-21
Abstract: Vulcanisation is carried out in a moving zone formed between the external periphery of a rotatable vulcanising drum and a flexible contact strip partly surrounding the drum. Novelty consists of controlling the peripheral speed of the vulcanising drum as a function of the continuously measured arc length of the vulcanising zone. The arc length of the vulcanising zone is measured as a function of the surface pressures on the outer periphery area of the vulcanising drum in the inlet- and outlet- zones of the vulcanising material. Faulty vulcanising causes can be overcome. The safety factor of rubberised fabrics, e.g. in inflatable rubber boats, can be increased.
