Title: Heat recovery from exhaust gases leaving boiler combustion chamber - uses gases to heat evaporator, as well as heat exchanger and condenser in heat pump circuit
Inventor: BEHRENS HARTMUT
IPC: F24D11/02
Filed: 1979-05-17
Abstract: The system is intended, e.g. for a central heating boiler, fired by oil or gas. The flue gases travel up a chimney after heating a heat transfer medium, which is e.g. water flowing through a pipe circuit contg. radiators. The chimney contains a shutter directing the flue gas onto the outside surface of an evaporator forming part of a heat pump through which a refrigerant circulates. The flue gas is thus cooled to below its dew point, thereby removing noxious substances before the cooled gas is released to the environment. The heat generated in the evaporator is transferred via a condenser forming a heat exchanger to the water employed to heat the radiators. The pref. plant includes a boiler from which flue gases can be directed into the heat pump circuit, which includes the evaporator, a compressor, and the condenser.

Title: Chlorinated fats to voluntary limit feed complement intake - by cattle and other ruminants, may also contain meat or fish meal, di:ammonium phosphate or ammonium sulphate
Inventor: BETZ NORMAN L
IPC: A23K20/158
Filed: 1980-08-27
Abstract: Compsn. contg. a chlorinated fatty substance is claimed, which contains sufficient bound chlorine so that when it is added to a feed complement it limits the ingestion of the complement by ruminants and limits feed consumption. The compsn. may also contain other substances which limit complement ingestion, such as flesh (e.g. fish) or meat meal, diammonium phosphate, ammonium sulphate or their mixts. The bound chlorine content of the fatty substance is pref. 0.2-7.0 wt.%, pref. above 0.5 wt.% partic. 0.9-1.5 wt.%. The fatty substance is usually animal or vegetable fats, which when chlorinated have pH 4.0-7.0. It is economic, when feeding cattle and other ruminants, to limit feed complements (proteins) to the amounts necessary to give good wt.gain or retention. This usually implies controlled rationing, to avoid the cattle eating more complement than is necessary. The present invention allows free-access by the cattle to the complement and automatically regulates the amount ingested.

Title: Fabric and thermoplastics sheet for tents or awnings - produced with thermoplastics foil drawn to reduce thickness before combining
Inventor: PAWELCZYK WERNER
IPC: B32B27/12
Filed: 1980-10-17
Abstract: A composite sheet composed of fabric faced with thermoplastic or elastomer is produced by conventionally calendering the thermoplastics or elastomer to produce the foil; this foil is then pulled from the last roll at a higher speed than the roll to reduce its thickness, and is then combined with the fabric sheet in a roll gap. The fabric sheet may be preheated before contact. The finished sheet may be subjected to an embossing process afterwards. Pref. thermoplastics or elastomer is calendered, and drawn from the last roll by a contact roll revolving at higher speed, the fabric passes over a heating roller before entering the roll gap where the two sheets are combined. The combined sheet leaving the roll may then pass over an embossing roll. Used for producing tent sheeting, tarpaulins, awnings, civil engineering fabric sheets etc. Arrangement enables wide sheets to be produced without excessively heavy roll pressures, but nevertheless with a very thin plastics foil, by the action of thinning the foil as it leaves the calendering section.

Title: Electrolysis cell for hydrogen esp. fuel prodn. - and sulphuric acid has porous ion exchange support structure between separators
Inventor: STRUCK BERND DIETER DIPL PHYS
IPC: C25B9/19
Filed: 1980-11-06
Abstract: Cell for the production of hydrogen and sulphuric acid from water and sulphur dioxide has an intermediate chamber which separates the anode from the cathode space and has electrolyte flowing through it; separators in the form of ion exchange membranes form the boundaries of this intermediate chamber. A porous supporting structure of ion exchange material is incorporated between these two separators. Preferably, the entire intermediate chamber is filled by the porous ion exchange material support structure and the separators with the electrodes directly adjoining them bear flat against this structure. More specifically, the supporting structure is of the same material as the separators and firmly bonded to them. Cell is used partic. for the electrolytic production of hydrogen and sulphuric acid by the sulphuric acid hybrid circuit process. Especially for the production of hydrogen as an energy carrier (fuel). It is found that, by incorporating an ion-conducting support structure between the separators, the internal resistance of a three-chamber electrolysis cell for hydrogen production can be reduced and the functioning rendered more efficient. In particular the migration of sulphur dioxide into the cathode space is prevented.
