Abstract: A signal intercept system intercepts an international calling frame, modifies a specific set of bits and then retransmits the frame in real time. The signal intercept system includes a communications processor and a signalling link interface. In one arrangement, the signalling link interface includes two intercept and transmit connectors and a coprocessor connector. In one arrangement, the communications processor includes a computer and a communications coprocessor. The computer maintains a data base with tables of such data as invalid calling card numbers. A computer program initializes and starts the communications coprocessor which handles high speed signal capture, manipulation and high speed signal retransmission. The communications coprocessor also interacts with the computer's data base to alter table parameters.

Abstract: A bracket stands upright on a base attached to the bracket with a hinge, the hinge being biased by a spring to hold the bracket upright and at right angles to the base. The bracket has horizontal slots located at intervals along its vertical length. A tray, containing holes designed to hold a pair of bowls, is attached to the bracket by a hinge. One of the hinge leaves connects to the tray. The free hinge leaf terminates in a flange adapted to fit in one of the horizontal slots on the bracket to support and hold the hinge and tray on the bracket. The height of the tray may be adjusted by placing the free hinge leaf into different slots. The hinge is configured to prevent motion of the tray downward below a horizontal position. The hinges allow the structure to be folded flat to allow storage in a narrow space when the structure is not in use.

Abstract: The waste stream is mixed with a solvent that absorbs the oily material without dissolving in the water phase. The remaining water/solids mixture is then separated by vibratory screening, and the solids are again contacted with solvent to remove the bulk of the remaining oily material. The remaining mostly solid material is screened again and then dried to remove any remaining solvent. The solvent is processed to remove the dissolved oily material, which is then sold or discarded. The water from the screening and drying steps is processed to remove any solvent entrained with the water, and the resulting solvent, solids and oil-free water is discharged.

Abstract: A method of forming a raised image of preselected pattern onto the surface of a fabric material by first laminating a thin film of vinyl onto the surface of the fabric and underlying the fabric with a thin layer of vinyl. A heated die of the image to be formed is then caused to be impressed in a highly forced engagement against the laminated film, while RF energy is applied to the die platen for a controlled time period. The die and image are permitted to cool in place after which the die is removed and any extraneous vinyl particles permeated during the heated engagement can be easily brushed from the fabric surface while the image pattern remains.

Abstract: Disclosed is an apparatus for protecting a swimming pool against damage due to forces created as water in the pool freezes and expands.

An annular centering surface within the receptacle engages the end of the rod to the center the rod within the connector. A plurality of evenly spaced dimples on the connector extend into the receptacle to the center the rod within the connector at a point spaced from the centering surface.

Abstract: An orthopedic pillow having separately adjustable neckroll and head-support sections. The neckroll section has a foam rubber pad rolled into a spiral roll and housed within a cylindrical case. The case can be opened to allow the pad to be removed and trimmed. The diameter of the neckroll can thus be adjusted to correspond to the contour of the user's neck. The head-support section has an outer section and an inner section. The thickness of the outer portion may be adjusted by adding or removing filler material. The thickness of the inner portion may be adjusted by adding or removing inlays in a stacked arrangement.

Abstract: A remote controlled spotlight system having a pair of spotlights on the ends of a horizontal shaft extending through a housing. A vertical shaft extends out of the housing for mounting purposes. An electric motor in the housing rotates the horizontal shaft about its longitudinal axis to aim the spotlights up or down. A second electric motor in the housing rotates the housing about the longitudinal axis of the vertical shaft to aim the spotlights left or right. The electrical motors are remotely controlled. An electrical power cord extends through the bore of the horizontal shaft, out through a hole in the horizontal shaft, and winds around the horizontal shaft at least twice. The cord then winds around the vertical shaft at least twice, and then passes through the bore of the vertical shaft to a power source.

Abstract: A drill pipe spinner having a body with an open throat for receiving a drill pipe. A pair of cylindrical driven rollers are mounted on the body for rotation about a vertical axis. A pair of pressure arms are pivotally mounted on the body for rotation about a primary pivot pin. A pair of secondary pressure arms are mounted on the primary pressure arms, for rotation relative to the primary pressure arm about a secondary pivot pin. A pair of cylindrical pressure rollers are mounted on the secondary pressure arms, for holding the drill pipe against the driven roller. A pair of piston and cylinder assemblies exert force on the secondary pressure arms, to cause the secondary pressure arms to rotate. The moment arms between the piston and cylinder assemblies and the primary pivot pins are shorter than the moment arms between the piston and cylinder assemblies and the secondary pivot pins.

Abstract: A torque wrench for making and breaking connections between sections of drill pipe. The torque wrench has upper and lower wrench assemblies, each having a gate, a latch, and a clamp. Clamping cylinders apply clamping pressure to the clamps. Torque cylinders apply torque pressure to the upper wrench assembly, to cause rotation of the upper wrench assembly relative to the lower wrench assembly. When the torque pressure is adjusted, a valve causes the clamping pressure applied to the clamping cylinders to automatically vary linearly with the torque pressure.

Abstract: Rotary power slips mounted in the rotary table of an earth drilling rig and having slips for gripping and releasing pipe in the rotary table. The air transfer ring has concentric grooves in the upper surface. An annular seal ring is secured to the body of the rotary power slips and has a pair of air passageways. The air passageways lead to secondary fluid conduits in the body, which, in turn, lead to each end of the pneumatic cylinders to raise and lower the slips. Expansive rings are secured to the surface of the air transfer ring by mounting the edges of the rings into the grooves in the air transfer ring. When air pressure is applied through one of the primary fluid conduits, one of the expansive rings expands and cooperates with the lower surface of the seal ring to form an expansive fluid duct. The air pressure flows through a perforation in the expansive ring into the expansive fluid duct, and then through the air passageway and the secondary fluid conduit to the pneumatic cylinders.
