Abstract: ABSTRACT OF THE DISCLOSURE             A digital carrier signal demodulation circuit is used in the carrier digital transmission system utilizing a 16-ary APK (Amplitude and Phase Keying) signal produced by the vector superposition of a second path signal consisting of a four-phase shift keying signal upon each phase of a first path signal consisting of a four-phase shift keying signal, the level of the second path signal being lower than that of the first path signal.  The received 16-ary APK signal is de-tected with the reference carrier extracted from the received signal, regenerated to reproduce the base band pulses of the first path signal.  The recovered base band pulses remodulate the reference carrier to produce the first path signal.  The phases of the recovered first path signal and received signal are compared to phase lock a voltage controlled oscillator thereby producing the reference character.

Abstract: A B S T R A C T      Method and apparatus for coating pipe utilizes a cen-tral coating station to coat pipe joints moving on two parallel spaced apart coating lines.  Two coating applicators disposed in opposed relationship adjacent the respective coating lines both receive coating material from a single central coating preparation station by a reciprocal conveyor.  Coating material is alternately supplied to the opposite applicator as different pipe sections are moved at intervals to first one applicator and then the next.  The conveyor is moved by a reversible prime mover.  A brake is automatically activated to slow the conveyor whenever a reversing switch is thrown.  This assures that the coating operation at the opposite applicator will begin in a minimal amount of time.  A holding hopper is also provided for receiving prepared coating prior to deposit on the reciprocal conveyor.  The holding hopper has a capacity adequate to allow to to continue receiving coating material for a period of time during reversal of the conveyor thus eliminating the need to stop the coating preparation apparatus.

Abstract: ABSTRACT OF DISCLOSURE            Essentially nonreflective coupling for ultrasonic waves is provided between a fluid medium confined in a rigid container and a biological specimen, such as a human body, through a container closing bellows system which incorporates a thin, flexible closing membrane that contacts and conforms to the contours of the specimen.  A supportive bellows system between rigid parts of the fluid container and the membrane gives the membrane the essential properties of conforming to the contours of a specimen having variations in curvature (concavities and convexities) while having the ability to contain the fluid medium without rupture or undue distension when it is not supported externally, as by contact with the specimen.  The supportive bellows system utilizes a pair of flexible toroidal members, one tubular and one U-shaped in cross section, attached to one another in series and having internal venting so that pressure within the toroids is governed by the pressure of the fluid inside the coupling bellows system.  The container closing bellow system is fluid filled, the flexible closing membrane is tautly stretched over the tubular toroid member so that it is supported by the bellows system and forms a fluid-tight closure, and a vent means is provided to adjust pressure inside the said container closing bellows system.

Abstract: ABSTRACT OF THE DISCLOSURE A container for liquids for use in medicine and surgery is made of flexible plastics material and a container volume is defined by heat seals at each end of the container. At one end of the container there are three ports one being a filling tube and the other two being outlet or additive ports which are sealed by frangible membranes.  To allow for expansion of air in the volumes outside those membranes the outer end of each of those ports open into expansion chambers defined by further heat sealed seams of the sheet or tube material forming the container.  A line of weakening enables these expension chambers to be torn off immediately before the use of the appropriate port so as to gain access to the port but so as meanwhile to have preserved the sterility of the outer surface of the membrane.

Abstract: IMPROVEMENTS IN SWITCH OPERATING MECHANISMS          FOR HIGH VOLTAGE SWITCHES            ABSTRACT: A three-phase, high voltage switch arrangement is operated through a connected drive shaft by a switch operating mechanism that can be either driven by motor power or manually operated.  When manual operation is desired, a crank handle is folded out of a stored position to an operating position.  An improved mechanism is provided to prevent the crank handle from operably engaging the switch operating mechanism until stored torsional energy (i.e., the potential energy due to torsional strain) in the drive shaft has been released, thereby avoiding improper operation, such as unexpected whipping of the handle.  In addition, when the crank handle is folded out to its operating position, the motor is disabled so that the motor can not be operated while the handle is engaged with the mechanism so that the handle cannot be driven by the motor. When it is desired to dis-connect the switch operating mechanism from the switch so that maintenance and testing can be performed, a selector handle may be operated that disconnects the drive shaft from the operating mechanism and locks the drive shaft so that the switch cannot be accidentally opened or closed due to wind or vibrational forces.  Also, while the selector handle is being operated, the motor cannot be operated while the drive shaft is being disconnected and locked.

Abstract: ABSTRACT OF THE DISCLOSURE       A vibration attenuating device to be used in conjunction with reciprocating-motion type impact mechanisms having working and stop members that are axially movable relative towards or away from one another.  The members define a pressure chamber therebetween, which is in communication with a source of pressure medium and is sealed by a flexible sealing material such as an O ring.  Each member is acted upon by a compression spring exerting a force on the individual member in a direction towards the other member.  The introduction of the pressure medium into the pressure chamber results in a cycle comprising the 1) members being forced away from each other, 2) the pressure medium escaping from the pressure chamber and 3) the members being returned to their original positions by the action of the springs.  The invention provides a completely balanced two mass system which is particularly useful in conjunction with impact mechanisms used for hand tools.  This balanced two mass system attenuates tool vibrations that would normally be trans-mitted to the operator of this tool.

Abstract: A B S T R A C T         In a method of error detection in a digital system, it is known to receive from a transmitter a serial  pattern of digits in which each digit, as transmitted, is a predetermined function of two or more digits each preceding that digit by a particular spacing in the pattern, and to compare a digit in the received pattern  with the combination, in accordance with the said predetermined function, of two or more digits preceding that digit by the said particular spacing in the received pattern and to generate an error indication when there is no correlation.  In this invention, the comparison is repeated for succeeding particular digits in the received pattern whilst omitting for use as the particular digit one or more digits in every n (where n is an integer greater than two).  The fact that not every digit in the received sequence is used as the particular digit provides a simplification of the circuitry required.  Every third digit in the received pattern may be taken as the particular digit and the received pattern may be a pseudo-random binary sequence of maximal length. Circuitry to implement the method may comprise shift-registers, means to divide digits between the shift registers and modulo-2 adders.

Abstract: Abstract of the Disclosure A nuclear fuel rod assembly is provided comprising a tube having a portion thereof defining a fuel chamber for nuclear fuel pellets, end closure means defining one end wall of said chamber and a stop member defining the other end wall.  The stop member is slidable within the tube and constructed to permit egress of gas from the chamber into a second portion of the tube.  Compression spring means are located inwardly of  the stop member and are adapted to abut a stack of fuel pellets within the chamber. A sleeve member is axially located in the tube and is slidable therein, a plurality of holes extending radially through the  sleeve member between the inner and outer surfaces thereof.  A ball is located in each said hole, and a tapered member extends axially into the sleeve from said stop member and tapers in a direction away from the spring.  The tapered portion of the member contacts the balls within the holes formed through the sleeve, whereby movement of the tapered member under the influence of the compression spring forces the balls outwardly into wedged engagement with the inner surface of the tube.  With the foregoing arrangement, a secure abutment means is provided for the compression spring without occupying the relatively large amount of space required by the conventional sleeve abutments of prior art devices.
