Patent DE-3942347-A1 (DE)
Inventor: TREBITZ BERND DR
IPC: D06F75/18
Filed: 1989-12-21
Abstract: In a steam iron (1) with a water reservoir (8), a steam chamber (10) with steam outlet openings (11) in the iron soleplate (2) and a first valve (9) which controls the water supply from the water reservoir (8) to the steam chamber (10), the water flow through the first valve (9) is controlled via the iron pressure force or the iorn movements by the iron soleplate (2) being displaceable in relation to the first valve (9) so that the pressure ram (23) opens the valve (9). As a result of this, steam is only produced when the iron (1) is moved to and fro on the article to be ironed with a given iron pressure force. Setting the iron (1) down in the vertical position is then no longer necessary to prevent unnecessary steam outlet. <IMAGE>

Patent DE-4001525-A1 (DE)
Inventor: IRIE TOSHIMASA
IPC: F24H4/04
Filed: 1990-01-19
Abstract: A heat pump capable of simultaneously supplying cold and hot fluids comprises a refrigeration cycle including a compressor 1, a condenser 2, an evaporator 4 and expansion valves 3; a path for a fluid to be heated connecting from a feed inlet 15 of the fluid via the condenser to a hot-fluid outlet 12; and a path for a fluid to be cooled connecting from a feed inlet 16 of the fluid via the evaporator 4 to a cold-fluid outlet 13. A refrigerant liquid-gas heat exchanger 11 is interposed in the refrigeration cycle to cause heat exchange between the liquid refrigerant and gaseous refrigerant in countercurrent flow. Both paths for the fluid to be heated and the fluid to be cooled are constituted as a once-through path. In the condenser, the refrigerant and the fluid to be heated are passed in countercurrent flow. Thus, a short rise time of operation, and a higher-temperature hot fluid and a lower temperature cold fluid than usual are obtained.   <IMAGE>

Title: Removing condensable and sublimable cpds. from gases - by regenerating two=stage cooling, with intermediate mist removal, then warming to ambient temp.
IPC: B01D7/02
Filed: 1990-01-22
Abstract: Condensable and sublimable materials (A) are removed from gas streams by regenerative cooling of the gas to 0-180 (pref. -30 to -70) deg.C by passing it through a cold storage mass which is simultaneously warmed. Any mist formed by cooling but not deposited is removed in a separator and the gas is cooled further to below the m.pt. of the residual components to be removed. These impurities are deposited in a storage mass of large surface area and high pore vol. and the purified gas is then warmed back to ambient temp. by passing through a warm storage mass (which becomes cooled). Periodically the flow direction of the gas is changed so that the functions of the cooling/warming masses are switched. This causes solid impurities to meet and discharge of liq. impurities from the mass and separator. USE/ADVANTAGE - The method provides efficient removal of (I) and recovery for reuse, e.g. it is applied to materials evaporating from fuel or chemical storage taks. The use of regenerative cooling/heating reduces the energy demands of the process.
