Title: Heat pump for room heating - has condensation temp. regulated by controller affecting only secondary circuit
Inventor: BIEN WOLFGANG
IPC: F24D19/10
Filed: 1980-12-24
Abstract: The heat pump for room-heating has a primary circuit containing a compressor, a condenser, and expansion valve and an evaporator. A secondary circuit extracts heat from the condenser, and contains a circulating pump and heat accumulator, the latter connected by feed and return pipes to the room-heating circuit. The condensation temp. is regulated by a controller (5,10,11,12,7) affecting only the secondary circuit so as to give ideal operating conditions with max. evaporator output and automatic expansion control, which is by thermostat. This prevents premature fall in the evaporator pressure, and the cut-off point of the low pressure pressurestat is only reached below 3 deg. Celsius.

Patent DE-3115769-A1 (DE)
Title: Blocking pin of a cylinder lock
Inventor: ZAHRADNIK PAVEL
IPC: E05B27/00
Filed: 1981-04-18
Abstract: The invention relates to a blocking pin of a cylinder lock, which serves for ensuring a higher security of the insert locks of the pin system. The previous use of blocking pins does not sufficiently ensure absolute security against an opening of the cylinder lock. The invention achieves a new version of the blocking pin, with the result that greater security against the opening of the insert of the lock is ensured, this being achieved in that the two ends of the pin are of conical shape and are formed from cone sides at the angle  alpha in such a way that, during rotation, the two cone sides rest with the entire generatrix against the wall of the orifice in the body of the insert. The advantages of the version according to the invention reside primarily in the increased security of the lock, so that the possibility that the lock will be opened by the reciprocal use of a similar type of closure on the key is eliminated. The two-sided conical blocking pin according to the invention can be used on all types of locks which employ a pin system.

Title: Softening device for domestic appliances, in particular for dishwashers
Inventor: SCHMIDT RUDOLF
IPC: A47L15/42
Filed: 1982-03-16
Abstract: In order to match the brine requirement needed to regenerate the ion exchange filling to the local degree of water hardness and, consequently, to the degree of exhaustion of the ion exchange filling, a water collection container (4) is provided above the salt container in a softening device. The volume of water which can be accommodated in the water collection container and which is used to introduce an appropriate amount of brine from the salt container into the ion exchange container can be adjusted to the local water hardness by means of a stopcock (15) which can be of compact design and can be rotated satisfactorily by means of a setting knob (13). Depending on its rotary setting, the stopcock provides a connection to one of a plurality of riser channels (21-23) by means of a transverse bore (16). The level of the openings of the riser channels of different height determines the possible filling levels (11, 26, 27) of the water collection container. If the stopcock is in a closed position, the water collection container can be filled up to its upper overflow edge (7) at a further filling level (6). <IMAGE>

Title: Process and agents for treating waste waters containing organic, water-insoluble substances in emulsified form
Inventor: WALD KLEMENS DIPL CHEM DR
IPC: C02F1/52
Filed: 1982-03-26
Abstract: In a process for treating waste waters containing organic, water-insoluble substances in emulsified form, in particular waste waters from vehicle washes, in which the emulsion is broken, the substances to be eliminated are flocculated by means of a water-soluble, organic, polymeric flocculating agent and are then separated from the water, a simplification of the treatment process is achieved in that a preferably water-soluble, polymeric aluminium chloride (PAC) is first metered into the emulsion and that then the organic flocculating agent is metered in. The polymeric aluminium chloride is used in a concentration between 3 and 1000 ppm, preferably between 15 and 80 ppm, and the organic flocculating agent is used in concentrations between 0.01 and 100 ppm, preferably between 0.3 and 2.0 ppm. Both agents can be added as an aqueous solution to the waste water. The water-soluble, polymeric aluminium chloride acts as an emulsion breaker in the treatment of the waste water described above.

Abstract: The invention relates to an arrangement for keeping livestock, such as pigs, cows, poultry, rabbits, in which the animals are kept individually or in a number together in stackable containers (boxes 2), these boxes (2) being arranged next to and above one another. The animals do not leave the boxes (2) during their entire rearing and during transport. During rearing, the boxes (2) are arranged offset in a step-shape in such a manner that the dung area (3) which has gaps is situated at the rear lower end of the box (2) freely above a manure pit (4). During transport, the boxes (2) can be both laterally offset and stacked above one another in the same direction. In the boxes (2), the air for inhalation is separated from the remaining stall air. This takes place via fresh-air supply nozzles (8) in the breathing region of the animals and can be increased additionally by a transverse diaphragm (flap 29) which surrounds the neck of the animal. It is particularly advantageous if each fresh-air supply nozzle (8) is assigned a draw-off pipe for the purpose of removing the exhaled air. Moreover, there can be provided in the body air part (14) of a box a warm-air nozzle which contributes to accumulating the body air and to raising the body air temperature (bed system). <IMAGE>
