Title: Rinsing and spinning in program-controlled washing machine - has several stages to cut water consumption without impairing rinsing effect
Inventor: KOEHNE JENS DIPL ING
IPC: D06F35/00
Filed: 1991-05-15
Abstract: A process is for rinsing and spinning laundry in a program- controlled washing machine. After the ending of the main wash, the washing solution is initially pumped off and intermediate spinning is carried out at 1,000 rpm. The drum speed is then lowered to 100 rpm and a specific amount of rinsing water is sprayed into the drum while the pump is switched off. The drum is subsequently brought to a speed of 800-1,000 rpm and the washing solution pump is switched on. After several such rinsing and spinning procedures, the washing is redistributed by means of reducing the drum speed while an increased amount of rinsing water is injected into the drum. After the redistribution, the drum speed is again raised to 800-1,000 rpm and additional rinsing and spinning processes are carried out in the same way. ADVANTAGE - Water consumption can be reduced without impairing the rinsing effect.
Patent DE-4117284-A1 (DE)
IPC: B01D61/14
Filed: 1991-05-27
Abstract: Gas and liquid separation with membranes has either been achieved by organic polymer membranes, which are limited by low temperature stability and a separation mechanism through adsorption or solubility in the membrane matrix, or by inorganic membranes, whose gas and liquid separation efficiency is limited by Knudsen diffusion. The membranes of this invention show a temperature stability up to 500 DEG C and a gas separation with separation factors better than the Knudsen limit. Continuous microporous inorganic membranes of any desirable thickness can be prepared by e-beam evaporation of metal oxides on a support membrane, which has substantially larger pores than the metal oxide membrane. It is advantageous when the support membrane consists of the same material as the microporous membrane. The membranes are of porous structure with a narrow pore size distribution of pores, where the majority of the pores have diameters smaller than 1 nm. The membranes can be used in all areas of gas and liquid separation, where the selective separation of smaller molecules from mixtures is desired (f.e. gas concentration by removal of water from natural gas, hydrogen from synthesis gas). The membranes can also be used for the concentration of aqueous solutions (fruit juices with retention of aroma compounds, vitamines and other compounds important for the flavor and nutritional value of the juice; biological liquids like lymphe, blood, or others with retention of valuable compounds including small peptides, hormones, antibiotics and others) and for the concentration of organic solutions with retention of molecules larger than the solvent including oligomers and polymers. The membranes can also be used for the concentration of waste water with retention of organic contaminants like phenol resins and coal oil at coking plants. If the membranes have been made catalytically active, the membranes can also be used for the selective and poison resistant conduction of heterogeneously catalyzed three phase reactions by having the reaction gas diffusing through the catalytically active membrane to react at the other side of the membrane with the liquid, consisting of molecules too large to penetrate the pores.

Title: Method of affecting end dia. of heated rollers - used in e.g. paper polishing and super-calender assemblies, comprises blocking heat loss by having external insulation at end zones
Inventor: GEROMILLER JOHANNES DIPL ING
IPC: D21F5/06
Filed: 1991-08-29
Abstract: To effect the dia. profile of the end zones of heated rollers such as in paper polishing and super calender assemblies, the heat loss at the end zone of the roller is blocked by external insulation. This increases the mean temp. of the roller and enlarges the dia. of the end zone of the roller and at the edges of the paper web. Pref. at least one thermal insulation body is round the ends of the roller mantle, as a thermal insulating varnish or a ring which slides axially over the end of the roller mantle. The ring can be fixed in place, and can be insulating tape wound round the end of the mantle. The ring can also be screwed into place, or it can be a U-shaped profile, open to the roller mantle. The ring can be held in place by mountings, with connections for the feed and exhaust of a heated or cooled medium. ADVANTAGE - The assembly gives a simple setting for the roller dia. and its temp. to avoid over pressing of the paper material without separate systems for the body of the roller and its end zones
