Abstract: ABSTRACT OF THE DISCLOSURE Precipitated silicas having a very high structure as defined by the ability of a silica material to hold water in its wet cake, high absorption, and very high surface area can be produced by controlling the rate of acidulation during their production between the levels of 1/x and 2/x hydrogen mols/ minute, where x is the weight ratio of sodium oxide of silica to the alkali metal oxide, and maintaining this same low rate during the entire course of the addition of acid to the solution of alkali metal silicate at temperatures of between 150 and 170°F. The control of the index of refraction of the silica so produced is achieved by introduction of controlled amounts of adduct material such aluminum sulfate to the acid prior to its intro-duction to the silicate solution.

Abstract: ABSTRACT OF THE DISCLOSURE           The invention is concerned with Specific sorbents based on hydrophylic polymeric gels, preferably or a macroporous charac-ter, which carry covalently bonded D-aminoacid or a peptide containing D-aminoacid units.  The basis carrier which is prepared by copolymerization of hydroxyalkyl esters of hydroxylalkylamides of acrylic or methacrylic acid with crosslinking acrylate or methacrylate comonomers is modified by reaction with diamines, aminoacids or dicarboxylic acids and the resulting carboxyterminal or aminoterminal groups are condensed with D-analogs of aminoacids or peptides.  The peptide containing D-aminoacids can be also stepwise synthetized on the surface of the carrier.  The specific sorbents of the invention are used as insolubilized inhibitors in the affinity chromatography of proteolytic enzymes.  They do not undergo an irreversible inactivation during repeated appli-cation and are suitable for technological purpose because of their mechanical and hydrolytical stability.

Abstract: DATA PROCESSING SYSTEM     Abstract of the Invention A data processing system in which the operating logic thereof is arranged to provide for an overlapping of the access, or "fetch" operations  such that access to a second memory module can be obtained by a processor unit before a data transfer has been completed with respect to a first memory module and read-out of the second memory module can process during the rewrite cycle of the first module to reduce the overall processing time.  Such operation is made even more effective by arranging the system to utilize memory interleaving techniques.  Further, the system of the invention can provide for multiprocessor operation with a single memory system by the use of appropriate time-sharing techniques wherein processors can be operated in time-phased pairs, suitable multiprocessor control logic being arranged to provide for preselected priority allocations among the multiple processors to permit the most effective management of the multiprocessor system.

Abstract: ABSTRACT    A driver circuit that permits full duplex transmission of digital data on a single signal line includes apparatus for enabling a receiver of a station having a transmitter and a receiver to ignore outgoing digital signals from the transmitter of the same station and receive incoming signals. The circuit includes two current switches and a differential amplifier that combine the incoming and outgoing digital signals in the signal line to form a composite signal which shifts between predetermined amplitude levels and that recover the incoming digital signals from the composite signal.  Using such n circuit a full duplex transmission system of a plurality of stations connected to a common single signal line is provided.  Such a system can be operated in a broadcast mode wherein one station can trans-mit signals to the remainder of stations.

Abstract: ABSTRACT A chain switch sewing machine is operated by two substantially parallel and horizontal levers, one of which is medially pivoted in the head and the other in the base.  The levers are connected together by a link and actuated by a crank directly connected to the upper level. The upper lever, which is slidable along its fulcrum to accommodate the throw of the crank, actuates the needle bar.  The lower lever actuates a swingable hook by means of a cam secured to the hook and pivoted therewith in the base.  A feed dog supported for vertical and horizontal movement in the base has a camming portion interposed between the cam and hook and which is also actuatable by the lower lever and by the cam.      A thread tensioner has smooth plastic surfaces between which the thread is passed and which can be urged together with variable tension by a cam acting through a spring.

Abstract: ABSTRACT                 In the manufacture of cathode ray tubes, the neck of the tube consisting of a lead-containing glass is closed by a glass base plate having sealed therein a number of contact pins on which an electrode system for generating at least two electron beams is mounted. The periphery of the base plate is sealed to the wall of the neck of the tube by local heating, the base plate being supported by a supporting member having guide holes and reference holes cooperating with the contact pins to determine the centering and the rotational position of the electrode system relative to a re-ference system of axes. In order to prevent (or inhibit) the lead released from the lead-containing glass during sealing from penetrating into the reference holes, said reference holes are substantially spaced from the base plate. This is realised in a simple manner by means of a supporting member in which each reference hole is coaxial with a guide hole and spaced from the surface of the member supporting the base plate.
