Abstract: ABSTRACT       " EQUIPMENT FOR DISENTANGLING BARS "            The invention relates to equipment for disentangling bars, particularly concrete-reinforcing bars. For this purpose it was already known to provide a storage bed consisting of relatively longitudinally spaced frames extending at right angles to the length of the bars and each  provided with upwardly directed substantially V-shaped mutually aligned cut-outs.  There were also provided vertically  liftable supports between said frames also extending at right angles to the length of the bars and each having a central portion formed with an upper edge of which the width is less than the maximum width  of  the  aforesaid V-shaped  cut outs. According to the invention a vertical slot extends downwards from the central portion of each liftable support, each such slot being provided with vertical guide  means  for  a  bulkhead which  is  vertically displaceable relative to its associated support.  In their raised position these bulkheads essentially form said central portions of the supports whereas in their lowered position they lie below the level of a conveyor formed by conveyor rollers mounted in the supports. After initial lifting of the supports some of the bars are left resting on said central portions thereof.When however the bulkheads are subsequently lowered those bars which were left on top of the central portions drop down said slots onto the conveyor rollers and are thereby very largely disentangled. This avoids the risk of bars slipping laterally off the supports during conveying because conveying now takes place  in a channel which is clearly delimited by the side walls of the vertical slots.

Abstract: DRIVE SYSTEM FOR AUTOMATIC CLOTHES WASHING MACHINE   ABSTRACT OF THE DISCLOSURE           A clothes washing machine wherein the clothes receiving basket is driven through a speed reduction transmission by an electronically commutated motor operable unidirectionally in one mode for rotating the basket to effect a spin extraction cycle, and in a second mode motor rotation is cyclically reversed to cause oscillation of the basket during the washing operation.  The speed reduction transmission is adapted to counteract the inertia of the basket generated by the high speed extraction cycle to provide a secondary braking action of the basket which supplements the dynamic braking capacity of the motor.

Abstract: CARRIER-PHASE ADJUSTMENT USING ABSOLUTE PHASE DETECTOR             Abstract Disclosed is a modulation-demodulation system and method for transmitting a plurality of sequentially received information bit sequences, thesystem including a transmitter (10) having a state machine (16) for expanding by a coding process each information bit sequence into an expanded bit sequence with a coded bit group portion and, in some cases, an uncoded bit group portion. The transmitter (2) further includes a modulator (18) for modulating a carrier signal by one of a plurality of multilevel symbols in a two-dimensional complex plane in response to each sequentially applied expanded bit sequence, with the coded bit group portion being used to specify a subset of the multilevel symbols which when rotated in the complex plane maps upon another subset for each adverse angular rotation and the uncoded bit group portion being used to specify for a selected multiple symbol subset the transmitted multilevel symbol of the carrier signal. The system further includes a receiver (50) having a demodulator (58) and slicer (60) for demodulating and detecting the modulated carrier signal to obtain the expanded bit sequences.   The object of the invention is to provide in the system a phase rotation detector (68), coupled to the slicer (60), for uniquely identifying each adverseangular rotation by analyzing a plurality of sequentially applied coded bit group portions; and a phase corrector (95), coupled to the phase rotation detector (68), for compensating for the adverse angular rotation.

Abstract: MODIFIED POLYESTER COMPOSITION          ABSTRACT OF THE DISCLOSURE         New and improved resin mixtures are disclosed comprising an aromatic polyester or copolyester resin; an aromatic polycarbonate resin, and a modifier combination therefor comprising an acrylate/methacrylate core-shell multiphase composite interpolymer resin and an olefinic resin selected from C1-C10 olefin homo-polymers and copolymers of an olefin and acrylic acid, methacrylic acid, or alkyl esters of such acids.  The resin mixtures exhibit retailed impact resistance at room temperature and improved tensile elongation, improved processability, moldability and extrudability. In a preferred embodiment, the acrylate/methacrylate core shell copolymer resin and the olefinic resin are precompounded to form a modifier concentrate.  Pre-compounding reduces the flammability hazards associated with blending rubber powders and avoids worker exposure to chemical dust.  In addition, the precompounded composition is more easily and completely dispersed in the other polymeric components providing improved part appearance and better melt flow and permits a reduction in the amount of core-shell interpolymer resin employed without sacrificing important physical properties.

Abstract: ABSTRACT           A boring head penetrates by means of a cylin-drical fastening spigot into a bore of a connecting shaft. A retaining screw with a conical turned end engages in such a manner in a conical transverse bore in the spigot that the boring head is tightened by wedge effect against the connecting shaft.  A cylindrical transverse bore is provided, approximately at right angles to the conical transverse bore, in the spigot, a longitudinally displaceable drive pin being supported in the cylindrical transverse bore.  The ends are, for example, turned to conical shape and penetrate with little clearance into recesses having a trapezoidal or semi-circular cross-section.  During the transmission of a torque, the drive pin is automatically centered, by which means the forces acting are evenly distributed between the two ends.  The device is also particularly suitable for the transmission of large torques with increasing or compelling requirement and is rotatively inserted to the left and to the right.
