Title: Domestic waste water heat recovery - in tubular coil surrounding plastic waste water container
Inventor: DEUBNER FRANZ
IPC: F24D17/00
Filed: 1979-02-12
Abstract: The heat of waste water from domestic appliances is recovered by inserting a plastic container with the waste water into a thin-walled tank, filled with water, in which a tubular coil carries the water to be heated. Brushes, fixed to a central rod, can be used to keep the bottom and side walls free from deposits, which are flushed out through a hose at the top. This eliminates any possible contamination of the clean water and ensures good heat transfer by keeping the container walls clean. Specifically an outer tank is filled with neutral water at atmospheric pressure to house a tubular coil for preheating cold clean water. An inner container, made of plastic, holds the hot waste water and is covered by the neutral water.
Patent DE-2907653-A1 (DE)
Title: Textile machine yarn monitor - has electrically conductive sensor for electric registration of yarn presence and speed of travel
Inventor: UNGER LOTHAR DIPL PHYS
IPC: B65H63/032
Filed: 1979-02-27
Abstract: Using a resistance of a high ohm value the charge is measured as a current to determine the presence of a yarn and its speed of travel. The current led off the yarn by the sensor is passed into an input amplifier with a high ohm value. It is then filtered and passed through a further amplifier acting as a rectifier to a comparator. The registered signal is compared with a reference signal, and the difference between them is used to illuminate an indicator or trip a stop circuit on the machine. The reference signal is extracted from the measured signal by a deep pass filter or a high order filter. The design gives a rapid and positive indication of a yarn break, using simple circuitry, when working with high yarn speeds, without being affected by dirt.

IPC: B01D53/26
Filed: 1979-03-27
Abstract: In this method a steam jet pump (70), into the high pressure inlet (71) of which steam is introduced from a hot steam line and from the low pressure inlet (72) of which a proportion of the hot steam emerging from the nest of tubes (18) is drawn, is used to prevent overcooling of the condensate in the tubes (22) of a reheater (10). The scavenging steam emerging from the steam jet pump under high pressure is then led to the inlet chamber (33) of the head (19) of the nest of tubes (18). <IMAGE>

Title: Car engine oil filter - connected to vacuum source to remove water by degassing
Inventor: ZIMMER CORNELIUS P
IPC: B01D29/00
Filed: 1979-04-20
Abstract: Oil from the lubrication circuit of internal combustion engines is regenerated and/or filtered in a casing contg. a folded filter paper cylinder, coarse and fine charcoal layers. A space is left above the oil as it overflows at the filter outlet. This space is connected to a vacuum source such as the suction side of the carburettor of the engine. The vacuum removes from the oil most of the moisture and the acids contained in it. The result is a better lubricity of the oil and a longer life for the engine; the absence of moving parts makes the device functionally more reliable.

Title: Coal dust gasification under pressure - with flow deflector near reactor discharge end
Inventor: SEIPENBUSCH JUERGEN DIPL ING
IPC: C10J3/46
Filed: 1980-05-06
Abstract: Pulverised coal gasification under pressure is carried out in a reactor where pulverised coal and/or a coal dust-liq. mixt. is injected and gasified in the presence of steam and oxygen to a gas contg. CO and H2. The coal dust particles are directed at least at the discharge end of the reactor against the inside wall of the reactor and/or on internal fitments representing a slag film carrier for the formation and maintenance of a fluid slag film. The reactor receives the coal dust through a burner, together with steam and oxygen. The refractory lining is cooled either just by the heat dissipation of the steel shell or by a built-in forced cooling. The reaction rate is stabilised by retaining a part of the coal dust particles on the surface of a flow detector. This improves the carbon conversion rate and compensates for the lower temp. gradient near the discharge end by a longer residence time. The thermal efficiency is increased.

Title: Gas burner regulation control - allows independent regulation of air valve for cooling after combustion cycle
Inventor: ALBERS LOTHAR
IPC: F23N5/12
Filed: 1980-06-16
Abstract: The gas control adjusts the gas supply and the air supply valve in dependence on a supplied regulation signal. A further input receives a second regulation signal used for independent adjustment of the air valve when the gas valve is closed. The second regulation signal is pref. supplied via an optical signal coupling. Pref. the second regulation signal is fed to an OR-gate with a second input receiving an air valve adjustment signal obtained from the first regulation signal via a programme control to adjust the opening of the air valve in accordance with the setting of the gas valve. The OR gate may also receive a fault signal from a selection circuit for the regulation control. The output of the OR gate is pref. fed to an AND-gate with two further inputs respectively receiving a signal indicating that the regulation control has been switched 'ON' and that the function of the regulation control is operating correctly.
