Title: Converting animal excreta into nontoxic products - with a composted mass from waste or sludge
Inventor: KNEER FRANZ XAVER
IPC: A01K1/015
Filed: 1975-12-23
Abstract: The process utilises a moist compost of average degree of ripeness, obtd. by biological decompsn. from waste and/or sludge, as the mass to react with the excrement. The compost has a water content of 30-55%, a pH of 5-6, and organic substance content of 55-70%, little mould, a fine, crumbly structure, a brown, turf-like appearance and an earthy smell. It also contains the microorganisms Actinomycetes globisporus, flavus and farinosus, fusngi (Coprinas spec., Aspergillus spec. and Mucor) as well as mites, nematodes and enchitrae. The process is used esp. for the battery raising of pig and small animals (e.g., fowl) whose excrement can lead to stomach and intestinal infection. Cleaning their stalls/pens is also hazardous for humans due to the high ammonia content of the air and other noxious gases. This process allows the excrement to be degraded in situ, thus avoiding these problems and improving the animals' health.

Title: Pipe coil for underfloor heating - is held in registers so that alternate straights lengths cross each other
Inventor: HASENMAIER HANS PETER
IPC: F24D3/14
Filed: 1976-04-06
Abstract: A pipe coil embedded in a floor for hot water heating is made of plastic tube. The tube is arranged in a continuous coil with semi-circular round sections joining alternate lengths of straight pipe. The circular sections extend over more than 180 deg. so that alternate straight sections are at an acute angle to each other. Alternate straights therefore cross each other between bends. Each straight passes first over and then under another straight between opposite bends. The pipe is held in registers with slots for the pipe. The registers are at each side of the coil at the ends of the straights and commencement of the bends. This arrangement enables the crossovers to fit in a confined depth.

Patent DE-2646690-A1 (DE)
Title: Oxygen and steam mixer for cellulose bleaching - has air fractionating plant supplying liquid oxygen to steam nozzle
Inventor: LINDE GERHARD DIPL ING DR
IPC: F25J3/04
Filed: 1976-10-15
Abstract: The oxygen is produced by low temperature fractionating of air. This oxygen is supplied at ambient temperature to the inlet of a nozzle compressor operated with high pressure steam. The low temperature fractionating is carried out in two pressure stages. The oxygen is drawn in liquid state from the low pressure stage. It is evaporated with a proportion of the air to be separated. This air is compressed to a higher pressure than the main quantity of air to be separated. The mixing arrangement is highly reliable in operation and no oxygen compressor is used.
