Abstract: PROCESS FOR MAKING HIGH-STRENGTH, HIGH-YIELD     SULFITE-MODIFIED THERMOMECHANICAL PULP AND A LINERBOARD COMPOSITION PRODUCED THEREFROM                     ABSTRACT         A high-strength, high-yield sulfite-modified thermomechanical pulp is formed by subjecting lignocellulose to multistage mechanical attrition, the first stage being conducted at elevated temperature and pressure and the second stage being run under atmospheric conditions. A sulfite chemical is added to the lignocellulose prior to the second stage, the lignocellulose being sulfonated so that a percent bound sulfur level of at least about 0.15% is provided. A novel linerboard composition is unexpectedly produced empoy-ing replacement quantities of the above described pulp.

Abstract: OPTICAL DETECTION WEIGHING SYSTEM                  Abstract of the Disclosure An optical detection system for a weighing scale includes an apparatus for generating a moire fringe.  Unlike prior moire-type systems, however, the present scale is constructed with a substantially rigid tare, so that movement of the moire is limited to only a portion of one fringe line.  Movement of the tare, and the pan carrying the load, are visually not apparent.  Response time is greatly enhanced by the inventive system and accuracy is improved due to minimized hysteresis loss;  The invention detects an optical shifting of the fringe line, rather than a counting of a number of fringe lines as with prior highly deflective scale systems.

Abstract: METHOD FOR MONITORING THE CONCENTRICITY  OF PLASTIC COATINGS ON OPTICAL FIBERS                  Abstract of the Disclosure The concentricity or eccentricity of a plastic coating on an optical fiber is determined by monitoring the absence or presence, respectively, of a particular intensity peak in the bac light pattern generated by a light beam incident upon the fiber as the fiber is drawn, coated and pulled through the light beam.  The particular intensity peak monitored results from the rays of minimum deviation which traverse the optical fiber only once as the incident rays are refracted and reflected through the coated fiber to form the backscattered light pattern.  The position of the coating applicator is automatically adjusted if this intensity peak is electronically detected.

Abstract: ABSTRACT OF THE DISCLOSURE   A bland protein product having a texture and mouth feel simulating animal meat is prepared from a dough-like mixture of proteinaceous material and water. The proteinaceous material can comprise relatively low protein content blends or even single ingredients such as soy flour. The process comprises continuously extruding the protein dough in the form of a relatively thin sheet of semi-rigid protein material into a confined treating zone while simultaneously subjecting the thin sheet in the extrusion die to externally applied heat to texturize both surfaces of the sheet before it enters into the confined zone. In the confined zone a stream of heated gas is directed at the thin sheet of surface-texturized protein to break off the leading segment of the sheet and further to propel the segments through the confined zone where additional texturization takes place. Finally, the protein segments are passed through a back pressure means at the end of the confined zone, and recovered in usable form. Apparatus for performing this process is also disclosed,

A slotted annular wall is interposed be between the chamber and the buckets, with the wall forming the entrance for dis-charged coolant fluid into the chamber. The wall has a plurality of adjacent sharply angled faces forming the annular inner surface and has slotted passages extending angularly and radially through the wall at the converging bases of adjacent angled faces. The angled faces of the inner surface diffuse the impact of the coolant fluid and direct the fluid to the passages and into the chamber.

Abstract: ABSTRACT OF THE INVENTION        A low-cost accessory for a conventional tank-type wet-pickup vacuum cleaner which converts such a vacuum cleaner into a self-contained hot water extraction type of carpet shamponer and floor cleaner suitable for use by homeowners. The accessory includes a reservoir which attaches compactly to the vacuum cleaner. The reservoir is intended to be filled with a cleaning solution of hot water and detergent and includes means for feeding the cleaning so1ution to a spray nozzle located behind the vacuum pickup nozzle. A hand-controlled valve permits the operator to dispense cleaning solution and to interrupt the flow of solution while vacuuming the wetted floor or carpet. In a pre-ferred embodiment the reservoir is a pressurizable toroidal-shaped tank which fits around the vacuum cleaner. The reservoir is pressurized by an integral manual air pump. An indicating pressure relief valve provides a measure of air pressure and prevents over pressurization of the reservoir. The air pressure forces cleaning solution to the spray nozzle. In a modified embodiment, a motor driven pump assembly is employed to deliver detergent fluid to tne point of use thus, eliminating the need for pressurization of the reservoir.

Abstract: ABSTRACT A method for preparing blood samples contain-ing red blood cells for automated analysis wherein the blood sample on a slide (20) is spun to create a mono-layer of randomly distributed red blood cells (40, 42, 46).  To inhibit cell morphology distortions from oc-curring during drying.  The morphologies of the cells contained in the monolayer are preserved by a fixing agent after monolayer preparation but prior to drying when such distortions would otherwise develop.  The method and apparatus are particularly useful for fixing red blood cells to prevent loss of or deformation of a central pallor which would be detrimental to a sub-sequent automated analysis.  A vaporous fixing agent may be conveyed through a conduit (26) into a spinning chamber (14) enclosed by a cover (24) of a slide spin-ning apparatus to provide a fixing atmosphere therein to begin fixing the wet cell before they can dry.
