Abstract: ABSTRACT      A rolling machine for reducing the cross-sectional dimensions of an elongate workpiece, such as a steel billet, has two pairs of alternately operating rolls, each of which is journalled in an individual roll carrier.  Each carrier is rotated about a carrier axis which is inclined at an angle of about 45° to the axis of rotation of the roll journalled in the carrier.  The carrier axes form the sides of a square around the pass-line which is normal to the plane in which the carrier axes are located.  As the carriers rotate the two pairs of rolls alternately sweep over the workpiece and intermittently contact and reduce the workpiece in directions which are mutually at right angles.  To avoid the formation of sharp edges to the rolled workpiece, either each roll is collared to enclose a work-piece edge, or each carrier additionally carries an edger roll which rounds that edge.

Abstract: NUMERICAL DISPLAY USING PLURAL LIGHT SOURCES AND HAVING A  REDUCED AND SUBSTANTIALLY CONSTANT CURRENT REQUIREMENT     ABSTRACT OF THE DISCLOSURE:       The present invention relates to a numerical display having a reduced dc current requirement per character display site. The invention is applicable to a variety of numerical displays including seven segment and 4 x 7 matrix displays using light emitting diodes, and low voltage incandescent segmented units designed to replace light emitting diode displays. A practical application is for displaying time in an ac powered clock or clock radio in which it is desirable to keep the dc current requirement of the display to a substantially constant minimum suitable for use with a low cost, transformerless power supply conventional with radio receivers. The current requirement of a character display site is reduced over that of full parallel operation by selectively serializing certain light sources in a manner leaving the display control circuitry uncomplicated by permitting each light source state to be controlled by a shunt control switch sharing a common bus. Since a seven segment display may assume 27 or 128 characters and only l0 (or 11) characters are used in a full numerical font, considerable control flexibility may be sacrificed by serial segment connection before any useful characters are eliminated. A display site having a full numerical font may be reduced from 7 to 4 branches and its current reduced 43% relative to full parallel operation under shunt control. Shunt control, which diverts, rather than prevents, current flow in the display, permits the display current to remain substantially constant irrespective of the numbers displayed. When the dc current drain of a time display is comparable to that of a radio and the ac component is tolerably low, the two may be serially connected without sub-stantially increasing the dissipation over that of the clock or the radio alone.

Abstract: ABSTRACT OF THE DISCLOSURE         A mass of diamond crystals in contact with a mass of eutectiferous silicon-rich alloy are disposed in a container and placed within a pressure transmitting powder medium.  Pressure is applied to the powder medium resulting in substantially isostatic pressure being applied to the container and its contents sufficient to dimensionally stabilize the container and its contents.  The resulting shaped substantially isostatic system of powder-enveloped container is hot-pressed whereby fluid eutectiferous silicon-rich alloy is produced and infiltrated as a bonding medium uniformly through the interstices between the diamond crystals and producing, upon cooling, an adherently bonded integral body.  The body contains diamond crystals ranging in size from about 1 micron to about 1000 microns.  The density of the diamond crystals ranges from about 70% by volume up to about but less than 90% by volume of the body.  At least about 85% by volume, and preferably 100% by volume, of the portion of the bonding medium in direct contact with the surfaces of the diamond crystals is silicon carbide.  The diamond body is substantially pore-free, and is useful as an abrasive, cutting tool, nozzle or other wear-resistant part.

Abstract: ABSTRACT OF THE DISCLOSURE      A surface acoustic wave device is used as a unique word detector and coherent demodulator for a digital code differential phase-shift signal. The device improves code word detection by providing a coherent reference with a correlation gain of 10 log M dB. M is the additional number of fingers introduced into the surface acoustic wave device, which determine the phase of the unique word. To achieve this result with higher reliability and higher correlation coefficient, use is made also of a few bits of the clock recovery which precede the unique word in a preamble as used in Time Division Multiple Access (TDMA) systems. The device requires two interdigital output transducers, one of which provides maximum output in response to surface acoustic waves representing the unique word, and the other of which provides a maximum output in response to surface acoustic waves corresponding to a preassigned pattern of the unique word, such as a sequence of all zeros combined with a partial sequence of the clock recovery bits. The outputs of the two interdigital output transducers are maximized at the same instant to detect the auto-correlation peak of the unique word with performance equivalent to coherent demodulation. Also, clock and data are recovered in the second set of interdigital transducers.
