Abstract: An apparatus for treating a waste solution generated when a photosensitive material is processed by an automatic developing machine includes a waste solution reservoir which is maintained at a constant level. A drum, partially immersed in the waste solution, is rotated to coat its surface. The drum is heated to produce a waste vapor. The waste vapor is condensed by a condenser and filtered and solid wastes are scraped from the surface of the drum. The condenser has a drain tank for collecting condensate and a non-condensable gas component. The interior of the drain tank is sealed to form an air tight seal and has a vent for exhausting the non-condensable gas component from the interior portion to the outside. The air vent includes an absorption tower to treat the non-condensable gas component.

Abstract: Fibrous and gelatinous vegetable matter is liquefied and frozen so as to result in a frozen food composition which is dripless and cohesive when exposed to temperatures above its melting point and which has reduced fat and cholesterol content. A preferred vegetable matter is edible rhubarb leafstalks. Various flavoring agents may be added to the vegetable matter. The frozen food composition closely approximates the characteristics of high grade ice cream. Even closer approximation to ice cream may be obtained by using dairy products as flavoring agents.

Abstract: A method of decreasing the viscosity and improving the evaporability of sulfate black liquor from the cellulose cook includes raising the temperature of the black liquor above the cooking temperature so as to split the macro-molecular lignin fraction contained in the liquor. The temperature of the black liquor is maintained at the raised level for 1 to 60 minutes, preferably for 1 to 5 minutes.

Abstract: An apparatus for supplying both hot water and distilled water includes a water distillation unit having a steam generator, a condenser connected with the steam generator for converting steam into distilled water and a holding tank for receiving distilled water from the condenser. The condenser is in heat transfer relation to the interior of a water heater tank. Water level monitors are provided for monitoring the level of water in the steam generator and the holding tank and temperature sensors sense the temperature of water in the steam generator and water heater tank. When the level of water in the holding tank is above a predetermined value, the steam generator is de-energized and feed water is admitted to the steam generator to dilute the contents to a safe temperature before the contents are discharged to drain.

Abstract: The present invention is directed to the use of certain ethoxylated compounds to increase the yield of chemical pulping processes, the compound have the following structures: ##STR1## These ethoxylated compounds have molecular weights of from about 500 to about 30,000 the (CH.sub.2 CH.sub.2 O) comprising from about 20 to 80 percent of the compound; and a, b, and c are each at least 1. The compounds are surface active agents which are added to the cooking liquor. The wood chips are cooked from about one-half and ten hours at a temperature of from about 200 and 500 degrees Fahrenhelt in a liquor including sodium hydroxide, sodium sulfide, and the surface active agent. The wood plug would have a reject level of at least 5% when the chips are cooked in the absence of the surface active agent. The process provides a simultaneous reduction in the level of rejects and an increased yield of pulp.
