Abstract: Apparatus for a continuous tandem electrical heat treating process for wire conductors for cables uses electrical contact pulleys having faces of a high melting point conductive material such as tungsten-copper. The melting point of the material is at least 1200.degree. C. The novel apparatus has reduced wear, arcing and wire breakage. Free running pulleys are also used instead of driven ones to avoid excessive tension. The free running pulleys have low torque contacts to apply high electrical current to heat the wire.

Abstract: A method for making a black matrix type shadow mask color television tube. A shadow mask with standard size apertures is sprayed with a black brushing cellulose lacquer while at the same time drawing air, at high velocities, through the apertures to reduce the size of said apertures. A sufficient quantity of sprayed lacquer is utilized to obtain a 10% reduction in aperture size. The mask is then utilized to coat the tube's screen, i.e. its inside face, with a colloidal graphite paint to form the required adherent black matrix surface on said screen having a plurality of holes therein. The apertures of the shadow mask are then restored to their original size by rinsing the mask in acetone to remove the lacquer coating. The resultant original size apertures of the shadow mask are utilized to form the pattern of phosphor dots on the screen overlapping the holes in the black matrix.

Abstract: An electronic resistance arrangement having symmetrical structure and properties comprises four series-connected negative-resistance elements having negative feedback operational amplifiers. A measuring current can be fed to the center of the arrangement whereby both halves of the arrangement can be independently controlled for compensating a resistance.

Abstract: The bread composition includes six different proteins and an amino acid. Some of the proteins are complete and others incomplete. The individual proteins are blended according to the method in a proper combination to produce a bread product having a high complete protein composition.

Abstract: An arrangement for providing controlled annealing of parts within a furnace comprising a series of heat radiation distributors, thermal conduction dosing devices and heat accumulators positioned within the furnace to provide a temperature gradient in the radial direction of the furnace cross section. The controlled temperature distribution within the furnace provides a controlled temperature distribution to the objects within the furnace during the annealing process. This controlled annealing process is particularly applicable to a method for controlling the coercive force distribution within a magnetically hard reed armature for matching the coercive force distribution along the armature to the magnetic flux intensity of the reed contact assembly.

Abstract: According to the disclosure, a tool is provided for measuring the thickness of fat in a carcass and producing a signal representative of the measured thickness, and means is coupled to said tool for receiving and storing a value representing a measured thickness.The method includes inserting the measuring tool into the fat of a carcass to produce a signal representative of the fat thickness, continuously receiving said signal corresponding to the measured thickness, indicating on said tool when the fat thickness has been measured, and storing in response to said indication the signal corresponding to the measured thickness.

Abstract: The bread composition incorporates a cellulose additive in precise amounts to produce a resultant white bread product having at least 25% less calories than the comparable standard white bread product. The composition also includes taste enhancements so that the reduced calorie bread will have the same eating quality and texture as the standard white bread.

Abstract: An optical waveguide coupler made by integrated optical circuit techniques is employed to direct light from a document to be copied to a line of photosensors of a large scale integrated photosensor module. A plurality of optical waveguides are spaced widely along the document and closely along the photosensor array. Spaced channels are formed in a higher refractive index glass layer on a glass substrate. The higher index layer glass provides the plurality of optical waveguides separated by the channels.

Abstract: Preferential etches for Gallium Arsenide and Gallium Aluminum Arsenide materials provide a novel single crystalline layer thin film of GaAs for use as a free standing transmission secondary electron emitter or as a photocathode layer on an intermediate epitaxial layer of GaAlAs. Etching of a central area of a substrate layer of GaAs provides an annular rim supporting structure for the epitaxial GaAlAs and GaAs layers. A particular composition of hydrogen peroxide and ammonium hydroxide preferentially etches GaAs while hydrochloric acid preferentially etches GaAlAs.

Abstract: An expandable cover for books is provided for storing, protecting and labeling data processing sheets, accounting records, and the like, comprising a pair of cover boards hinged to corner members which carry openings for receiving sheet attaching means, spine elements for the back of the book cover which have at least one opening for receiving a back or spine protecting element therein, or alternatively, an expandable element such as a foldable material, stretchable material, or further alternatively, a slot in one of the spine elements which slidably engages the second spine element by means of a rivet like member.

Abstract: There is disclosed a method and apparatus for sorting and classifying cans involving a first step of magnetically separating ferrous and bimetallic cans from aluminum cans. The aluminum cans are then carried to a collecting point. The next step is to separate the ferrous cans from bimetallic cans by immersing both in a liquid bath. The bimetallic cans and some punctured ferrous cans (such as large juice cans) are collected from the top of the bath and carried to a size separating device. The ferrous cans, which are normally fully opened, sink in a bath and are collected by a conveyor from the bottom of the bath. The bimetallic cans and the punctured cans are separated by sizing conveyors and are collected in separate collection devices. The result is to achieve a separation of the three basic classes of cans, reliably and inexpensively.
