Patent DE-4015273-A1 (DE)
Title: Dry-cleaning machine - has air recirculation through heater to remove per-cpds. and give drying action for spot identification
Inventor: FRAUENDORF MANFRED
IPC: D06F43/08
Filed: 1990-05-12
Abstract: To extract per compounds and identify spots in garments, after the cleaning and drying cycles in a cleaning machine, the inner air of a 2 m3 cabin is recirculated through a heater, selectively warmed by steam, electrical current or hot gas, to flow through the cabin and the garments. The heating action accelerates the dispersion of remaining per compounds from the garments, and they can also be steam heated. After a given time interval, an exhaust flap and exhaust fan are started in parallel, and the air charged with per compounds is fed through the exhaust channel to an active carbon filter for disposal. The length of the heating and blowing  the exhaust fan can be varied as required by overwriting the programmed times. In the program, a steaming phase follows the heating and air exhaust cycles. In parallel, the temp. is raised to ironing temp. of 65-70 deg.C through the heater and the recirculating fan. On reaching the ironing temp., the garments are dampened by a steam blast for 10-15 secs. The steam blast gives the pulse to open the exhaust flap at the exhaust channel and, in parallel, the exhaust  fan is started to dry the parts for later spot identification and further minimise the residual concentration of per compounds. ADVANTAGE - The system gives a per compound presence of 7 ppm in a zone of  m3, which is within the legal requirements.
Patent DE-4017303-A1 (DE)
Title: Cross-wound bobbin winder - has doffer which exchanges bobbins and start winding according to pattern of paired bobbins at intermediate store
Inventor: KATHKE GREGOR
IPC: B65H67/06
Filed: 1990-05-30
Abstract: To produce cross-wound bobbins at a winder, where the winding stations give bobbins with two preset wound yarn lengths, the bobbin which has been fully wound first is placed in an intermediate storage zone until the other bobbin is ready. When the doffer replaces a full bobbin with an empty sleeve, the number of bobbins in the intermediate store is taken in account at that winding station when generating a coded start command signal for the length of yarn to be wound on to the sleeve for the next bobbin. If the doffer detects that there are no bobbins in the intermediate store, when a bobbin is removed at a winding station, then its coded command start signal for winding on to the new sleeve is for the longer length of yarn to be wound. Unfinished bobbins, or bobbins which do not meet given quality criteria, are not placed in the intermediate store by the doffer. When the second finished bobbin is laid in the intermediate store, the formation of a pair of bobbins is reported by the doffer through a signal to the control, to prepare the removal of the paired bobbins. The doffer does not change the bobbin at a winding station if the intermediate store is occupied by two bobbins, nor if the intermediate store contains only one bobbin which carries the longer length of wound yarn. ADVANTAGE - The method ensures that, when winding bobbins in pairs, the winding action is correctly performed even in the event that one of the pair is absent.

Inventor: JUCHEM FRANZ-JOSEF
IPC: A21D6/00
Filed: 1990-11-26
Abstract: Semi-prepared products containing flour have hitherto been made stable by deep freezing. A new process of bacterial reduction is to be developed which enables these products to be put into interim storage with normal cooling without significantly changing them. A suspension is prepared from flour and a liquid, such as water, eggs and/or milk, which is treated for 5 to 240 minutes with a gas to which it is inert such as carbon dioxide at a pressure between 2 and 100 bar. In this way, all bacteria are significantly reduced, so that instead of deep-freezing, storage in a refrigerator until the finishing processing of the semi-prepared product is adequate. The process is suitable for all mixtures containing flour and a liquid, and leads to no contamination of the semi-prepared product.

Title: Fine grain bed decontamination - by using suspension with nutrient salts for microorganisms in a bio-reactor to degrade toxic organic matter
Inventor: KLEMPS ROBERT DR
IPC: C02F3/12
Filed: 1991-05-24
Abstract: To decontaminate fine grain beds, soiled by toxic organic matter, a suspension is formed from the bed material and water. The water contains the nutrient salts for the metabolic activity of the micro organisms, in the form of phosphates, trace elements, co-substrates e.g. sugar, ethanol or lactic acid. The bed/water suspension, at a rate of up to 50 wt.%, is agitated in a mixer or directly in a bioreactor. As an oxidising agent, nitrate is used alone or combined with other oxidising agents e.g. sulphate, bivalent Fe or Mn and CO2. When all the components for the bio process have been added, the suspension is stirred in the bioreactor at 10-20 deg.C with air exclusion. USE/ADVANTAGE - The process is for the decontamination of masses contaminated by toxic organic matter with a high fine grain content, e.g. loose or overgrown beds, sludge, harbour slick, or the fine grain fraction pptd. from earlier chemical/physical bed cleaning stages, and inert carriers soiled such as by aliphatic and aromatic hydrocarbons, polycyclic and halogenised hydrocarbons and cyanides. The technique gives an effective cleaning action to fine grain and clogged bed material, under controlled conditions, in a cost-effective action and economic time scales.

Title: Animal pharmaceutical for control of pigeon populations - comprises non-resorbable carrier in which substance inhibiting reproduction is uniformly distributed
Inventor: RADEMACHER KARL-HEINZ DR RER N
IPC: A61K9/22
Filed: 1991-06-06
Abstract: Animal pharmaceutical (I) for the temporary inhibition of the reproduction of town pigeons consists of a carrier formed from a hard, non-resorbable matrix in which is homogeneously distributed the active ingredient which is at least one substance which inhibits reproduction. Pref. reproduction inhibitors are sparingly water-soluble and the matrix is a PMMA. Carrier is approximately the size of a grain of maize and coating is coloured and flavoured. Active ingredient is steroid hormones, esp. levonorgestrel and ethynyloestradiol, esp. in amts. of 0.3 mg and 0.1 mg respectively. (I) can also contain other substances which influence reproduction, esp. substances which affect calcium metabolism. USE/ADVANTAGE - (I) is readily eaten by the pigeons, along with their feed and lies in the pigeons' stomachs for several months. Active ingredient is released as (I) is abraded by the stones in the pigeons' stomachs and so a uniform concn. of active ingredient in the birds is obtd. over several months. In female birds, temporary sterilisation is obtd. and in male birds the mating instinct is reduced, while the general health of the birds is unaffected. Pigeon population is reduced by natural deaths and is not over-compensated for by reproduction.

Title: Energy generation system using earth surface heat - uses circulated refrigeration medium vapour fed through expansion turbine
Inventor: NITSCHKE R-PETER
IPC: F24J3/08
Filed: 1991-12-06
Abstract: The energy generation system provides heating and hot water for a single family home using a Savonius rotor with a refrigeration medium vapour passed axially across it, for providing turbulence with a reduced pressure at its core. The higher radial pressure at the turbine rotor surface drives a second rotor. The refrigeration medium vapour is fed through a pipeline system for heating to 0 degrees C.

Patent DE-4190653-A1 (DE)
IPC: C02F1/44
Filed: 1991-03-06
Abstract: In a process for supplying or processing washing water for washing installations for vehicles, the contaminated water in a water-preparation or purification installation passes through at least one mud separator (1) and at least one oil separator (2), which separate gas and mineral oil in floating form or in droplet form, into at least one buffer container (3) from which the water for the washing operation is withdrawn and the contaminated water undergoes filtration during processing. According to the invention, the water from the buffer container undergoes fine filtration (5), without the use of flocculation agents, in particular salts, to filter out the floating oil-laden dirt particles or the floating oil particles mixed with dirt, before it is used for washing operations. The water so filtered, which still contains the essentially stably emulsified residual oil constituents, is used, in particular directly, for washing operations, or in automatic washing machines or installations. At least one washing operation, preferably the preliminary wash and/or main wash, is carried out with this filtered water.
