Title: Apparatus for using hazardous waste to form non hazardous aggregate
Inventor: KENT JOHN M
IPC: F23G5/16
Filed: 1990-11-28
Abstract: Hazardous waste is formed into non-hazardous non-leaching aggregate by introducing the material to a rotary kiln where the large solids are at least partially combusted to form a primary aggregate. Gaseous combustion by-products and waste fines from the waste materials are introduced into at least one oxidizer having water-cooled metal walls. Some of the waste fines are melted to form a molten slag-like material that is removed from the apparatus and cooled to form non-hazardous aggregate. The portion of the material in the oxidizer that is not melted, is cooled, neutralized and subjected to a solid gas separation. The solid is reintroduced to the oxidizer with the primary aggregate where they are either melted or entrained within the molten material and become an integral part of the non-hazardous aggregate. <IMAGE>

Title: Process for extracting impurities from natural cellulose
Inventor: MAGIN BERTHOLD
IPC: D06L3/02
Filed: 1991-01-07
Abstract: ABSTRACT OF THE DISCLOSURE         Disclosed is a method of extracting impurities from natural cellulose.  The method includes placing the material in a kettle and evacuating the material preferably in the dry state.  Subsequently, a treatment liquid is introduced into the kettle to impregnate the material.  The treatment liquid may be lye or acid and may optionally contain other chemicals.          The amount of the treatment liquid is not more than 3 parts by weight per part of the material.  Subsequently, saturated steam of a temperature above 100°C is conducted through the impregnated material until an excess pressure of at most 8 bar is reached in the kettle.  The material is kept at this pressure for about 1 to 5 minutes.  After releasing the pressure from the kettle, the material is washed in the hot state.  If necessary, the treatment steps can be repeated, possibly with the use of different recipes for the treatment liquids.  By employing the evacuation step and a small amount of the treatment liquid, the treatment time is substantially reduced.

Abstract: A signal processing system of an optical fiber gyro comprises a light emitting element for generating a monochromatic light, a fiber coil, a branching element for dividing the monochromatic light into clockwise and counterclockwise lights, for transmitting the clockwise and counterclockwise lights to opposite ends of the fiber coil, respectively, and for uniting again the clockwise and counterclockwise lights into a coherent light, a light receiving element for detecting an intensity of the coherent light, and an auxiliary light receiving element for monitoring an output of the light emitting element.  When the light emitting element output is less than a predetermined value, a power for driving the light emitting element is controlled so that a direct current component or even times higher harmonics component of a sensor signal obtained from the light receiving element becomes constant.  When, on the other hand, the light emitting element output has reached the predetermined value, the light emitting element output is controlled by a monitoring signal of the auxiliary light receiving element so that it does not exceed the predetermined value.
