Abstract: ABSTRACT OF THE DISCLOSURE    CERAMIC ARTICLE, RAW BATCH FORMULATION, AND METHOD       An impervious, virgin soda-lime glass-based ceramic article is disclosed.  The impervious ceramic article of the present invention is prepared from a raw batch formulation including virgin soda-lime glass cullet and clay.  The article of the present invention has aesthetic and physical properties which are precisely reproducible.  A raw batch formulation for making an impervious soda-lime glass-based ceramic article is also disclosed.  In a preferred embodiment, the raw batch formulation includes greater than 60 to about 85 weight percent virgin soda-lime glass cullet; from about 15 to about 40 weight percent clay; and from about 0 to about 10 weight percent flint.  A method for making an impervious virgin soda-lime glass-based ceramic article is further disclosed.  The method comprises dry-mixing a mixture including virgin soda-lime glass cullet and clay to form raw batch material; adding a sufficient amount of a volatilizable liquid to the raw batch material while mixing at a sufficient speed to produce granules of the raw batch material; heating the granules to remove part of the volatilizable liquid therefrom to form partially dried pellets; uniformly distributing the partially dried pellets in a die cavity of predetermined shape; uniformly applying pressure to the uniformly distributed partially dried pellets in the die cavity to form a green body compact; drying the green body compact to a moisture content of less than about 1 weight percent by weight; and firing the dried green body compact to form an impervious virgin soda-lime glass-based ceramic article of predetermined shape.

Abstract: ABSTRACT OF THE DISCLOSURE         A start signal is generated for parallel-synchronous operation of three substantially identical data processing units, an array of three identical unit outputs parallel-synchronously assuming concurring binary states, or a plurality of output arrays transmitting mutually like data words, respectively.  Due to individual random start-ups, the units are caused to perform in parallel mutually different data processes.  Each of three EXOR-responsive bit comparators or word comparators, respec-tively, are connected via the output arrays to two of the units. The start signal is sent from an AND-element having its inputs connected to three monostable elements, the inputs of which are connected to the bit comparators, or is sent from an AND-element which has its inputs connected to the word comparators, respec-tively.

Abstract: A thermoplastic tape is wrapped around a package and is tightened by the disclosed strapping or banding apparatus. The ends of the plastic tape can be welded together by a combined strapping and sealing apparatus or even with a separate sealing apparatus. The strapping apparatus includes a positioning system which ensures that a slotted wheel intended for tightening the plastic tape, once the operating cycle is complete, always assumes an optimum position for the re-insertion of the plastic tape. The use of the strapping apparatus is thereby substantially facilitated, since the operator normally does not have any hands free to adjust the slotted wheel that would otherwise be necessary for tape insertion.

Abstract: A cribbing device for trenches which includes a pair of opposing supports spaced apart by a spreader, each support having a plurality of guide profiles and a crosspiece. The crosspiece is disposed transversely to the longitudinal axis of the trench, and the guide profiles are arranged adjacent each other on said crosspiece. The guide profiles include a plurality of legs disposed vertically and extending outward from the crosspiece, and a plurality of flanges disposed vertically and secured to the legs at the ends of the legs opposite the crosspiece. The flanges project beyond both sides of the legs. A plurality of cribbing boards each having a guide bar which supports a guide head is provided. The guide head is in the form of a slotted hollow box section and extends vertically beyond the board at its vertical face side. The width of each guide profile flange is slightly smaller than the inside width of the guide heads. The slot of the guide heads corresponds to the legs of the guide profiles, and the inside spacings between the legs of the adjacent guide profiles is slightly larger than the total width of the guide heads. The boards may, therefore, be guided and supported by the supports by engaging the guide heads of the boards with the guide profiles of the supports thereby permitting the boards to be passed by each other on parallel planes and to be supported by the supports in a form-locked manner.

Abstract: Production of core antigens of the virus HTLV-III and their use in detection of antibodies in sera of AIDS and pre-AIDS patients, and to biochemical and immunological analysis of antigens associated with the virus HTLV-III. The utilization of p24 and p41 core antigens enables a greater specificity of detection. It is shown that antigens associated with the infection of human cells by the virus are specifically recognized by antibodies from AIDS patients. Specifically, HTLV-III isolated from AIDS patients and transformed by occultivation with an HT cell line is specifically detected by antibodies from human sera taken from AIDS patients. The p24 and p41 antigens are used to monitor the precense of HTLV-III in cultured cells and cell-free culture fluids, where virus infection is suspected, and also to monitor antibodies in human sera. The method of detection of antibodies preferred is a radioimmunoassay (RIA), ELISA (an enzyme-linked immuno-sorbent assay) or indirect immunofluorescene assay.
