Title: Variable output absorption heat pump - has heat exchanger formed by auxiliary absorber fed from conveyor outlet
Inventor: ALEFELD GEORG PROF DR
IPC: F25B30/04
Filed: 1979-03-03
Abstract: The absorption heat pump works with material contg. vaporising and absorbent ingredients, the former being ejected from it by an expeller with an adjustable heater. From the expeller the absorbent ingredient passes through an expander, while the vapour flows through a condenser where heat is conducted away by a heat exchanger, and then through an expansion valve reducing the pressure to below the vapour pressure at the expeller outlet. The vaporising ingredient then passes through a vaporiser to an absorber with heat exchanger extracting useful heat. The heat exchanger, to which vapour is fed, bypassing the vaporiser (30) from the expeller (10), is formed by an auxiliary absorber (42', 42"), to which working material is fed from the delivery outlet (52) as absorbent.

Title: Control of DC-energised gas discharge lamp - regulates lamp operation to give equal illumination time with each polarity
Inventor: KARIUS HELMUT
IPC: H04N1/028
Filed: 1979-12-14
Abstract: The control is for appts. typically photo copiers or image transmitters - employing gas discharge tubes with non-point forming illumination. Where such tubes are operated from a d.c. supply light emission from the anode falls off with time due to accumulation of active atoms, typically of mercury, at the cathode. To increase the useful life of the tube a control circuit is proposed which records and stores the polarity and duration of successive on periods. A polarity change is automatically ordered if the period immediately ending exceeded the length of the penultimate period of opposite polarity. In this way the lamp is operated, in the longer term, with equal periods at each polarity. As the atom migration effect is reversible the lamp life is extended.

Title: Sewage and industrial wastes utilisation - by precleaning, distillation producing steam for power generation, and heat pumps
Inventor: SCHYMURA HEINZ-JUERGEN
IPC: C02F1/04
Filed: 1980-01-29
Abstract: Municipal sewage and industrial wastes are passed through a precleaning station where the coarse solids are removed. The clarified liq. is then distilled to recover all chemical cpds. which are dissolved in the liq. The steam produced is passed through turbines to generate electricity and the remaining heat is extracted from it by heat pumps. The raw materials, recovered by the precleaning operation, can be used as building material or for landscaping. The steam, produced by the distillation, can be used for a district heating system after it has left the turbines. The resulting condensate is completely pure and causes no pollution when discharged in the drainage system. This eliminates the environmental pollution by imperfectly cleaned sewage and industrial wastes. It recovers valuable raw materials and chemicals and produces electricity from waste.

Title: Deep drawn thermoplastics beakers with labels fitted simultaneously - by looped label strip suspended in mould and tacked to thermoplastics foil in two places
Inventor: FINNAH JOSEF
IPC: B29C51/16
Filed: 1980-05-06
Abstract: Method of producing beaker-shaped packaging containers from plastics foil, with a label on a flattened outer region of the beaker wall, consists of intermittently advancing and heating a flat plastics foil, tacking the labels to it at intervals and deep-drawing the beakers into appropriate depressions in a mould so that the labels bond to them. An endless strip of labels is drawn from a reel and fed to the lower side of the advancing thermoplastics foil band, as it leaves two heating plates. The strip of labels is then formed into a loop associated with each beaker to be produced, tacked at its front and rear ends to the underside of the thermoplastics foil, and becomes bonded to the thermoplastics as the latter is deep-drawn into the form of a beaker. As the beakers are cut to separate them from the continuous thermoplastics sheet, so the label is simultaneously cut with its associated beaker. Different shapes and sizes of beakers can be readily accommodated.

Inventor: DUDECK GUENTER
IPC: C21D11/00
Filed: 1980-05-20
Abstract: A heat resistant powder is fluidised so the heater element can be immersed in the powder, and then the fluidisation is stopped. An electric current is fed through the element to anneal it; and the temp. of the element is measured by its thermal expansion. When the length of the element has increased by a specified amt., the electric heating current is switched off, and the powder is re-fluidised to cool the element. The pref. plant consists of a tank fitted with vibrators to fluidise the powder, and also with a perforated base used to feed an inert gas through the powder. The heater element is lowered into the powder by a jig with two clamps used to feed electric heating current through the element, which can also be stretched to length while hot. Process is used to stretch a tubular heater element to a required length; to anneal the element; and also to diffuse a protective coating, e.g. Ni, into the tube. A fully automatic process and plant with a low cost and low energy consumption is obtd. The plant provides savings in manual labour and in the vol. of inert gas required.
