Abstract: Abstract of the Disclosure Precision makeup at high speed of the most used forms of pipe and casing for production wells is assured by a novel coupling system. A pipe collar is provided with an internal precision makeup ring whose length along the pipe axis assures precise positioning and engagement. When the nose of the pipe is engaged with metal-to-metal contact against a reference shoulder on the precision ring a side surface on the nose end of the pipe engages a center seal ring disposed in the side wall of the collar between the reference shoulder and the threaded portion. This seal constitutes an effective barrier against the leakage of high internal pressures into the thread engagement region. End seals are mounted in grooves in the end recess portions of the collar, outside the threaded engagement region, to provide seals against external pressure, which can also vent internal pressures that are in excess of a predetermined threshold. With this arrangement, a modified standard collar or a manufactured collar can be placed on a pipe or casing off the drill rig floor, with the axial length of the precision ring being selected to assure makeup tightness adjusted to particular axial strees conditions. Makeup on the right floor requires only stabbing of the next pipe section into the collar and engagement until metal-to-metal contact is achieved and seals are concurrently established. Pipes and collars can readily be prescreened to eliminate a minor proportion of elements whose thread tapers vary more than is permissible for the given conditions.

Abstract: ABSTRACT OF THE DISCLOSURE         Rapid lock or synchronization between a reference oscillator and a voltage controlled oscillator in a phase locked loop circuit is achieved by a synchronizing circuit.  The synchronizing circuit senses the magnitude of the ramp signal produced by the phase locked loop circuit, and produces a blocking signal when the ramp signal exceeds a predetermined level.  This blocking signal is applied to one of the oscillators to block that one oscillator pulse during the blocking signal, thus moving the two oscillator signals closer together more quickly, and thus providing lock of synchronization more rapidly.

Abstract: INTERPOLATING FUNCTION GENERATOR       FOR TRANSMITTER SQUARE ROOT EXTRACTION             ABSTRACT OF THE DISCLOSURE      A function generator for extracting the square root or other function of a pulse width modulated input signal is disclosed.  The function generator utilizes a ROM table (12) which contains values of the inverse of the desired function.  Two eight-bit counters (26, 28) are clocked in proportion to the duty cycle of the input signal and the duty cycle of a flip-flop (22), which is related to the out-put of the ROM (12).  The counters (26, 28) keep a running average of the comparison of the foregoing duty cycles  and,  in turn, cause a four-bit up/down counter (30) and the ROM (12) to cycle in time between the value in the ROM (12) above and below the exact input value.  In this manner, the output of a four bit up/down counter (30) is an accurate interpolated representation of the square root of the input signal.

Abstract: ABSTRACT OF THE DISCLOSURE             A vending or dispensing machine is operable in triple depth, double depth, and single depth operating modes.  A cradle which is rotatable through 360° is used to separate cylindrical articles from a number of tandem nonstaggered vertical columns.  The rotatable cradle separates a single can or other cylindrical article from each of the columns disposed in a storage zone above the cylindrical cradle and drops the cans into an escrow zone.          One of the cans in the escrow zone is immediately dispensed.  If operating in a triple depth mode, the remaining two cans are held by side mounted pivotable escrow members which are controlled and movably operable by the cradle itself.  Upon a second activation the cradle moves further in its sequence allowing one of the escrow members to release its hold on a second can such that that can drops into a dispensing zone accessable to a consumer.          A further activation of the cradle causes it to release the second escrow member such that the third and last can in the escrow zone is released for gravity movement into the dispensing zone.  The cradle then rotates around and segregates three more cans from the columns as the sequence starts over.

Abstract: "THREE-DIMENSIONAL RETICULATED STRUCTURE HAVING       TAPERED ENDS"                         Abstract A three-dimensional reticulated structure or space lattice structure is formed of metal rods tapered at their ends so that the loss of cross-section leads to a thicken-ing of the tubular wall of the rod, whereby it can be threaded at its ends by removal of material without losing mechanical strength. This is preferably attained by coining through at least six successive passes in dies of increasing ly smaller dimensions. The knots or junctions are bored metal cups, said rods converging into the bores thereof and being fixed simply by bolts. A plug of concrete reinforced with steel fibres closes the base of the cup while allowing its reopening for inspection and maintenance, and provides further mechanical strength to the assembly.

Abstract: ABSTRACT OF THE DISCLOSURE A dryer felt comprising a plurality of spiral coils disposed in a common plane and arranged in a side-by-side relationship with adjacent coils being intermeshed and joined together in a hinged relationship by a hinge yarn. During manufacture, the fabric is subjected to a heat treatment under controlled tension to cause the spiral coils, which are normally circular or elliptical in cross-section to assume the shape of the hinge yarns which are typically of rectangular, elliptical, D-shape, dog bone or two or more circular cross section yarns with the long side of the stuffer yarn lying in the plane of the fabric. In this way, the air voids within the fabric are substantially filled by the hinge yarns to reduce permeability, while the flattened spiral coils provide smooth paper-receiving and machine roll contacting surfaces on the resultant dryer felt. The coils are formed from yarns having a non-circular cross section and with their respective longer axes oriented in a direction generally parallel to the upper and lower surfaces of the felt. -21-
