Abstract: ABSTRACT OF THE DISCLOSURE            In a packet-switched communications network, the variable component of a delay suffered by the first packet of a message is estimated at a receiving node and compared with a desired minimum delay selected to be just sufficiently large to encompass most expected delay variations, the result of the comparison being used to set a clock controlling reconstitution of the received signal so as to subject the received packets to a delay approximating to but not less than the desired delay.  The estimate of the variable delay component is successively updated during reception of further packets to converge on the actual value of that component, the clock at the receiving node being updated accordingly to bring it into synchronization with a transmitter clock, sub-ject to a lag equal to the desired minimum delay.

Abstract: Abstract:          A solid product resulting from the nucleated growth of the product on solid material of either the same or different composition and having a density higher than the reaction medium is formed from one or more liquid phase reactants by a method which comprises tangentially introducing the liquid phase reaction medium into the lower, smaller end of an inverted, frusto-conical reactor-separator, thereby imparting an upward swirling motion to the reaction medium in the reactor-separator, the horizontal velocity at the bottom of the reactor-separator being sufficiently large to cause fluidization of larger, solid product particles and con-centration of them in the central lower portion of the reactor-separator and the vertical velocity at the top of the reactor-separator being sufficiently small to avoid carry-over of the smaller solid particles but sufficiently large to concentrate them in the upper portion of the reactor separator; at least periodically recovering the larger, solid product particles in spherical form from the bottom of the reactor-separator; and recovering fluid products from the top of the reactor-separator.  The method described is useful in a variety of reactions wherein a solid product forms by a nucleated growth mechanism.  Examples of such reactions include thermal upgrading of petroleum derived feedstocks and coal liquids, synthesis  of zeolites and Ziegler-natta polymerization of olefins.

Abstract: PIEZOELECTRIC MICROPROBE                 Abstract of the Disclosure A probe detects sonic energy in liquids and in mater-ials containing liquids such as the flesh of living beings, the probe being particularly adapted for medical ultrasonics.          The probe is constructed of materials having acoustic imped-ances substantially equal to that of water to maximize the transfer of sonic energy in a living being to an electric signal within the probe for accurate detection of high fre-quency pulses having a duration less than a microsecond.  A piezoelectric polymer serves as the transducer and is mounted at the end of the probe housing between a thin metallic window which serves as one electrode, and a metallized rubber rod which serves as the second electrode and sonically insulates the transducer from the housing.  An acoustically absorbent ring affixed to the perimeter of the face of the probe, and a flaring of the back end of the probe, reduce the diffraction and reflection of acoustic waves for improved accuracy in the measurement of submicrosecond pulses.

Abstract: ?1608 ABSTRACT OF THE DISCLOSURE         An arrangement for bidirectionally driving a hammer bank shuttle assembly along a linear path in a line printer includes an opposite pair of circular, rotatable elements having an elongated shuttle assembly mounting element and an elongated counterbalancing element extending between the pair of rotatable elements on the opposite sides thereof.  Pole pieces and a magnet disposed between and adjacent the shuttle assembly mounting element and the counterbalancing element provide magnetic flux which flows through portions of the opposite elements to attract and maintain the elements in contact with the opposite rotatable elements.  A pair of serially coupled coils mounted on the counterbalancing element and disposed within the air gaps formed by the pole pieces and the magnet are energized by a cyclically varying signal to bidirectionally drive the shuttle assembly mounting element and its included hammer bank shuttle assembly along the linear path as the counterbalancing element is caused to reciprocate between opposite limits of movement defined by an opposite pair of resilient elements in the path of movement of the counterbalancing element. In an alternative embodiment the coils are disposed between the counterbalancing element and the shuttle assembly mounting element so as to form air gaps with and magnetically interact with a first pair of magnets mounted in spaced-apart relation along the length of the counterbalancing element and a second pair of magnets mounted in spaced-apart relation along the length of the shuttle assembly mounting element.

Abstract: METHOD AND APPARATUS FOR TESTING      SNUBBERS INN SITU                   Harry E. Sulzer Telford, Pennsylvania ABSTRACT OF THE DISCLOSURE           A method and apparatus for testing seismic shock ab-sorbing snubbers in situ.  Such snubbers are used in power plants in association with piping that is yieldably attached by way of pipe hangers or supports to the plant building structure. Typically, snubbers are operatively connected between the pipe and the building or other support structure.  Such snubbers per-mit free motion of the pipe in response to slow thermal expan-sion or contraction of the pipe, but resist or damp rapid motion of the pipe induced by seismic shock or vibration.  In a method aspect of the invention, the snubber system permits testing in situ by loosening, but not disconnecting, a connection between the snubber and the pipe (or, alternatively, between the snubber and the support structure) to permit limited motion between two relatively movable sections of the snubber, without inducing movement of the adjacent pipe; then applying a test force be-tween the relatively movable sections of the snubber to cause relative movement therebetween to determine the operation of the snubber.

Abstract: Abstract of the Disclosure A lightning detection system utilizes a gated magnetic direction finder for determining the range and direction of lightning discharges to ground.  Logic circuitry is provided for controlling gating circuits within the direction finder so that the direction measurement is made during the initial few microseconds of the return stroke waveform, thereby minimizing errors caused by nonvertical lightning channels to ground, branches and in-tracloud discharges.  Distance measurements are made by analyzing the ampli-tude of the detected return stroke waveform, or by utilizing two or more geographically separated direction finders and triangulation techniques.  The waveforms of the signals received by the direction finder are analyzed to determine whether the discharge is a ground stroke or another type of dis-charge, or background noise.  Further circuitry can be used to distinguish between various types of ground strokes, such as first strokes or subsequent strokes in a flash.
