Abstract: The disclosure provides methods for improved hematopoietic stem cell transplantations, including methods to enhance protection from graft versus host disease while maintaining effective immune responses such as graft versus tumor immune responses. The disclosure provides methods for administering, for example, hematopoietic stem and progenitor cells, regulatory T cells, and conventional T cells, wherein the conventional T cells are administered after the hematopoietic stem and progenitor cells and regulatory T cells. The disclosure also provides methods for administering, for example, hematopoietic stem and progenitor cells, regulatory T cells, and conventional T cells, wherein the regulatory T cells have not been cryopreserved prior to administration.

Abstract: This invention is constructed of strong lightweight durable material like synthetic thermoplastic resin 5 mm thick or another material with similar characteristics. The material is cut into panels of a specific shape and dimension and bonded together with a proprietary adhesive process. The worktable surface is rectangular. Underneath the work table are two rectangular panels, each attached vertically at a 50° opposing angle, apart 6½? at the top and 15.5? at the bottom. These are referred as the angled gravity studs. Underneath and 14? from the top is a rectangular panel, which is attached horizontally from side to side. This is the stabilizing bar. At the bottom top side of the worktable is a rectangular panel, attached horizontally and from side to side. This is the shelf panel. The work table is grasped by two hands and lifted up and over the crown of the steering wheel.

Abstract: A reflexive fuel heating system for fuel entering the fuel filter of an engine comprises a heat exchanger disposed between a fuel tank and the fuel filter for transferring heat generated in a gear type fuel pump to the fuel.

Abstract: An apparatus and method for processing image data to derive edges and line segments. Image intensity data is processed in one dimension along a series of scan lines to produce an intensity curve (10). Pairs of points along a scan line curve (10) representing curvature extrema (20) are checked to determine if the intensity difference between the curvature extrema (20) are characteristic of edges. Edge points are then determined between pairs of curvature extrema. Edge points found between curvature extrema (20) are then correlated with other edge points in previous scan lines to determine if they fall within a range of predicted line segments. Line segment data may then be processed at higher levels to identify objects in the data.

Abstract: A rotatable regenerator of toroidal configuration is frictionally driven by a single roller disposed internally of the toroid.

Abstract: A method of detecting fires utilizing its flicker frequency spectrum provides a standard theoretical flicker frequency spectrum which is compared to the real time spectrum over a 2 second time period. The comparison includes whether or not the real time fire spectrum deviates from the idealized fire spectrum by a minimum amount and has further discrimination against false fire signals, including the extent of time of the real time spectrum is outside a predetermined window and a limit on maximum deviations.

Abstract: A method of making a turbine nozzle comprises the steps of forming a destructible mold in the configuration of a fluid passage through said nozzle, coating the mold with a succession of layers of different materials, removing the mold so as to form a hollow vane segment, assembling a plurality of hollow vane segments in a circumferential array, and bonding the vane segments to one another to form the nozzle.

Abstract: A rotatable toroidal regenerator has a pair of circumferentially spaced annular seals disposed thereabout that separate the hot and cold sections of the regenerator from one another.

Abstract: A puffable food composition is provided by extruding a mixture of ground animal parts and starch whereby the mixture is at least partially gelatinized during extrusion into a shape-sustaining form. The form is puffed either at the die of the extruder, or in subsequent hot oil frying, or both. With added flavoring, the puffed composition has the taste, texture and mouth feel of fried pork skins. The process accommodates a wide variety of animal parts without the necessity of substantial changes in the process parameters.

Abstract: A puffable, thermoplastic composition derived from animal parts is prepared by drying substantially raw animal parts to a moisture content between 10% and 25%, comminuting those parts and mechanically defatting the comminuted particles to a fat content of less than 18%. The defatted particles are macerated in an extruder at temperatures less than 330.degree. F. and under sufficient pressure to cause gelatinization of the particles. The resulting thermoplastic moldable mass is extruded to a shape sustaining form and cooled to below 215.degree. F., after which it is cut into puffable pellets. The pellets will be at least partially gelatinized animal parts, have a moisture content of less than 15%, a fat content of less than 15% and the protein thereof will not be subjected to denaturing temperatures in excess of 330.degree. F. The pellets may be puffed in hot oil to a product which resembles fried port skins or they may be thermo-formed into a decorative shape, e.g., in the shape of a chewable dog bone.
