Abstract: A TOOL UNIT FOR COLLECTIVE BREAKING           OF OPTICAL FIBERS                 Abstract of the Disclosure The end faces of a plurality of parallel optical fibers are all located in one plane at right angles to the general direction of the fibers after simultaneous cutting by a tool unit comprising a sliding shoe which carries a cutting-tool support.  During translational displacement of the shoe, the cutting edge of the tool scores each optical fiber in turn.  A flat, parallel array of fibers is stretched tangentially to the top generator-line of a bearing cylinder and held in position between two clamping members on each side of the bearing line.  At the level of the notch formed in the glass fiber by scoring, each optical fiber is split in transverse cross-section by applying an abrupt tensile stress or flexural deformation to the fiber.

Abstract: ABSTRACT OF THE DISCLOSURE          A motor having a rotor shaft extending through a casing, the shaft carrying an armature is disclosed, in which the distance between the assembled front and rear bearings of the motor is affected by accumulated manufacturing tolerance.  The distance is therefore indeterminate, being variable in the order of plus or minus .060 inches.  The end of the assembled rear bearing is a first reference point.  A self-locking unitary retainer ring grips the shaft in a location on the shaft axially outboard of the rear bearing.  The retaining ring is referenced to a variable second reference point at the end of the motor casing.  The location of the second reference point varies in accordance with the variable accumulated tolerance for a given motor.  The retainer ring can be moved along the rotor shaft, and the spacing of the inner surface of the retaining ring from the assembled rear bearing is automatically determined by a spacer of fixed dimension, the spacing corresponding to the difference between the substantially fixed distance from the first reference point at the end of the assembled rear bearing to the second reference point at the end of the casing and the sum of the thickness of the spacer and the thickness of the retainer ring.

Abstract: TITLE A PARTICULATE SOLIDS CONVEYING AND DRAINING DEVICE     INVENTORS Frederick W. Meadus Bryan D. Sparks ABSTRACT OF THE DISCLOSURE         A particulate solids conveying and draining device, for mounting in a solids outlet wall, comprising a funnel-shaped rotor with particulate solids scooping members attached thereto.  Each particulate solids scooping member comprises a paddle scooping portion leading to a liquid draining, particulate solids spilling, rib portion.  In operation, the rotor is rotated so that the particulate solids scooping members scoop a slurry of the particulate solids and, on rotation, drain liquid therefrom through liquid return ports to the centre of the funnel-shaped rotor and back to the slurry.  When particulate material reaches its angle of repose on a particulate solids scooping member, it tumbles across and off the rotor on the other side of the outlet wall to that at which the slurry is situated.

Abstract: "Esters of mercapto acyl-carnitines, process for their prepara-tion and pharmaceutical compositions containing same".                Abstract of the disclosures A novel class of esters of mercapto acyl-carnitines is dis-closed, wherein the mercapto acyl radical is the radical of sat-urated mercapto acids having from 2 to 10 carbon atoms. These esters of mercapto acyl-carnitines are prepared e.g. by first preparing the corresponding ester of halogen acyl-carnitine and then substituting therein, by nucleophylic substitution, the -SH group for the halogen atom.    These esters of mercapto acyl-carnitines are useful therapeu-tic agents, e.g. for the treatment of intoxications and burns, and as mucolytic agents.

Abstract: ABSTRACT     A high speed code processing system for error correcting code is disclosed.  It uses bit parallel residue generation for cyclic codes.  This minimizes the time delay for cyclic code processing.  Residue generation of the bit string is accomplished by processing multiple bits in each clock time in-stead of the conventional bit-by-bit implementation.  Thus, the checkword calculation and the syndrome calculation are accomplished at a significantly higher speed than the conventional shift register approach to provide a system capable of on-line residue generation.

Abstract: ABSTRACT The device for identifying registering marks in colour printing includes two reading heads (30 and 31) connected by an amplifier (32) to an analyzing device (33) to treat the information read on the web (2) running over an engraved cylinder (38).  An angular encoder (37) calculates the angular posi-tion of the engraved cylinder (38) while it rotates, and transmits it to the analyzing device (33) which memorizes the received information from case to case.  The analyzing device (33) also sends out a signal (36), in order to control the idler roller (41) creating a positive or negative elongation of the web (2) between two points (47, 48) of it.  The elongation, thus achieved, allows the identification of the registering marks, by comparing the two different registering mark reading results.
