Title: Microbiologically sterile flushing water for lavatories - is produced by gamma rays from liq. drawn from disposal tank and is discharged normally
Inventor: BANSEMIR KLAUS DR
IPC: E03D5/016
Filed: 1975-06-23
Abstract: The steriliser for making microbilogically sterile flushing liquid is used in toilets drawing flushing liquid from disposal tank with pump driven liquid circulation. The water for flushing is drawn from the disposal tank and filtered for flushing. No disinfectants are added because sterilisation is carried out by gamma ray irradiation. The gamma ray source is installed between the pump and the flushing liquid container connected to disposal tank. The liquid used for flushing must dwell for at least two seconds for radiation. Additives such as dyes and aromatic substances are mixed into flushing liquid. Especially blue dyes can be added. The advantage is elimination of disinfectant supply and metering systems into recirculating flow, although radioactive waste is produced. The gamma ray source (4a) is held in a container through which the contaminated liquid flows into flushing tank (5).

Patent DE-2638425-A1 (DE)
Inventor: SCHLOESSER HELMUT
IPC: B65H63/06
Filed: 1976-08-26
Abstract: When the thick place (8) of the thread (7) travels past the drive (P) of the switch (17), the latter is switched on immediately at the start of the travel past the thick place. The voltage of the source (16) is thus applied to the reset input (R) of the digital counter (11). According to the pulse train occurring at its clock input (C), the latter begins to count immediately. The number of its counting pulses to the emission of a pulse signal is permanently set. The switch (17) remains switched on only during the travel past the thick place (8). If there is no overshoot in the digital counter because of a short thick place, the evaluation logics (12) do not receive a pulse signal. If they receive a pulse signal because of a long thick place, the relay (14) is cut in by means of the following transistor (15) and generates an evaluatable signal. Moreover, this is stored in a memory device of the evaluation logics, which can be erased again by an external signal by means of an erasing device. The pulse train can be generated by an oscillating-crystal oscillator (24) with frequency divider (25), by an adjustable RC-oscillator (29) or by a machine-cycle sensor. <IMAGE>

Title: Domestic laundry drying cabinet with heat exchanger - has automatic controls and air circulating system ensuring uniform drying
Inventor: BALTES HANS
IPC: D06F57/12
Filed: 1976-10-18
Abstract: Flat goods, esp. items of domestic laundry are dried in a cupboard; air being drawn in from outside, compressed and heated. The air blown through from one side of the interior of the cupboard is directed against the edges of the goods, and is drawn away from the other side with part of its heat energy exchanged with the cold air coming in, or with an auxiliary stream of cold air or water. The drying air from the laundry items is blown into a condenser for the removal of part of the water carried over, and simultaneous cooling before being vented into the atmos. The fresh air is drawn in by a fan and fed through the condenser for preheating. It goes then through a heater to the goods to be dried. When the drying air is moved in a closed circuit, the condenser is cooled by a stream of air returned to the outside, or by a stream of water. Overcomes the problem that in conventional dryers the items near to the air outlet require a longer drying time. This extends the drying period of the whole charge and puts out very hot air.
