Abstract: TIME STAMPING FOR A PACKET SWITCHING SYSTEM            Abstract A communication method and packet switching system in which packets comprising logical addresses and voice/data information are communicated through the system by packet switching networks which are interconnected by high-speed digital trunks with each of the latter being directly terminated on both ends by trunk controllers.          During initial call setup of a particular call, central processors associated with each network in the desired route store the necessary logical to physical address information in the controllers which perform all logical to physical address translations on packets of the call.  Each network comprises stages of switching nodes which are responsive to the physical address associated with a packet by a controller to communicate this packet to a designated subsequent node.  The nodes provide for variable packet buffering, packet address rotation techniques, and intranode and internode signaling protocols.  Each packet has a field which is automatically updated by the controllers for accumulating the total time delay incurred by the packet in progressing through the networks.  Each processor has the capability of doing fault detection and isolation on the associated network, trunks, and controllers by the transmission of a single test packet.          The testing is done solely in response to the test packet and no preconditioning of controllers or networks is necessary.

Abstract: "GROUND WORKING SWEEP"          ABSTRACT OF THE DISCLOSURE     A ground working sweep comprises a flange for supporting the sweep body and provides two cutting edges lying in a horizontal plane extending rearwardly and out-wardly from a central point at the front of the sweep. The point lies forwardly and below the flange and the point and edges lie in a horizontal plane.  In comparison with the conventional sweep, a pair of wings are added at the rear ends of the cutting edges so as to provide an additional cutting edge having a sharp change of direction relative to the outward direction of the first cutting edge.  The outermost point of the cutting edge lies on an edge extending rearwardly from the cutting edge.  The change in direction in the cutting edge acts to cut weeds running back along the cutting edge and the wings reduce the tendency of wear to decrease the working width of the sweep.

Abstract: SIMULTANEOUS TRANSMISSION OF SPEECH AND DATA OVER                 AN ANALOG CHANNEL            Abstract The present invention relates to a technique for recovering each of an entire analog speech signal and a modulated data signal simultaneously received over a transmission channel such as a common analog telephone speech channel.  In the received composite signal, the entire modulated data signal is multiplexed within the normal analog speech signal frequency band where the speech is present and its signal power density characteristic is at a low level.  Separation of the speech and data signals at the receiver is effected by recovering the modulation carrier frequency and demodulating the received signal to recover the data signal.  The data signal is then (a) remodulated with the recovered carrier, (b) modified to cancel phase jitter and frequency offset errors detected during the data demodulating process and (c) convolved with an arbitrary channel impulse response in an adaptive filter whose output signal is subtracted from the received composite data and speech signal to generate the recovered speech signal.  To improve the recovered speech signal, a least mean square algorithm is used to update the arbitrary channel impulse response output signal of the adaptive filter.

Abstract: S P E C I F I C A T I O N      BE IT KNOWN THAT ROBERT G.BRIGHT, a British subject, of Viersen, Germany, have invented certain new and useful improvements in and relating to CHANNEL-SHAPED STRIPS, of which the following is a Specification.     ABSTRACT OF THE DISCLOSURE      A sealing, trimming or finishing strip has a metal carrier advantageously made up of U-shaped side-by-side metal elements interconnected by integral connecting links.  The carrier is completely embedded in flexible material, such as rubber or plastics material, which defines inner gripping and sealing lips.  A sealing portion is also provided.  Substantially all of the material on the inside of the carrier (including the material of the lips) is sufficiently transparent or translucent to enable the carrier, or at least the connecting links thereof, to be visible through it. This facilitates cutting of the strip into lengths, because it enables the cutter to be located so as to cut through the connecting links of the carrier, rather than through the U-shaped elements thereof.  The channel-shaped material externally of the carrier is visually opaque.

Abstract: ABSTRACT OF THE DISCLOSURE       A circuit for reducing noise and increasing the reliability of touch panels involves the use of a supplemental noise or electromagnetic interference pickup lead (63) which extends generally coextensively with the parallel connected outputs from a series of successively coupled photodetectors (42) and high pass filters (49, 58, and 60 and 64, 65 and 66) for substantially reducing the noise signals created by variations in the level of ambient light,  When the photodetectors output (46) is connected to one of the inputs (-) of a differential operational amplifier (56), and the com-pensating pickup lead (63) is connected to the opposite polarity other input (+), the noise is substantially can-celled out, and a cleaned-up photodetector pulse is provided.  A pulse forming circuit (74, 75 and 77) squares up the photodetector output signal pulse; and a hysteresis type storage or buffer circuit (76 and 78) is employed to indicate the presence or absence of photodetector output signals, from successive photodetectors, thereby indica-ting whether or not the light beams are interrupted either fully or partially.

Abstract: ABSTRACT A head assembly is disclosed for an internal combustion engine.  The assembly is comprised of a cast ceramic body with a coefficient of thermal expansion less than 1.0 x 10-6 in/in/°F (lithium aluminum silicate) fitting over the cylinder block of the engine to define a combustion chamber.  The ceramic body has passages for hot gases extending between the combustion chamber and a side wall of the body, but the body contains no passages for conventional water cooling.  A metallic shell sealingly envelops and is spaced from the body via compliant members and is effective to trap heat within the combustion chamber and passage means.  The shell sealingly clamps the ceramic body to the cylinder block of the engine.  The shell supportably carries mechanical subassemblies which extend into the ceramic body for controlling the flow of gases therethrough. The shell carries at least part of the compressive loading imposed by the clamping.

Abstract: ABSTRACT OF THE DISCLOSURE          A method and apparatus for anchoring rock bolts and cables in drill holes is disclosed.  The method of the invention comprises mixing a dry aggregate-cement mixture with a limited, predetermined amount of water in a water fitting and blowing the wetted cementitious mixture through a delivery tube into a drill hole, in which an anchor cable or rock bolt has been inserted, resulting in the cable or bolt becoming permanently anchored in the drill hole.  The use of a wetted dry cementitious mixture eliminates leakage of mixture from the drill hole and obviates the use of a plug, cover or collar plate.         The equipment includes a pressurized, dry mix delivery vessel, a source of pressurized air, a water fitting for wetting dry mix with water and a delivery tube for delivery of the wetted dry mix into the drill hole.
