Abstract: The invention combines a plurality of ultrasonic ranging transducers (11) arrayed proximate the end (12) of a movable robot arm (13), all transducers (11) being mounted to a common base so as to be pivotally movable both horizontally and vertically relative to the robot arm (13) by stepping motors (17 and 20). By controlling the pivotal movements of the transducer array (10) by a microcomputer (22) so as to look in the direction of intended travel of the robot arm end (13), and as to the robot arm end (13) moves, unexpected objects in the path of the robot (14) or aberrant motion by the robot (14) become easily detected. Upon the sensing of an obstruction to the direction of motion of the robot arm (13), or aberrant motion thereof, a signal from the microcomputer (22) to the robot (14) controls will halt further operation until the obstruction is removed or the problem corrected.

Abstract: A tensioner (10) is disclosed for use in tensioning connecting lines (16) connecting a marine riser (14) to a floating platform (12). The tensioner (10) is a passive system which incorporates a series of cylindrical elastomeric members (42, 54, 60) which are deformed in torsion to exert the proper tension on the connecting line (16). A specially tapered drum (30) is provided on the tensioner so that the radial distance from the axis of rotation of the drum to the position where the line leaves the drum varies to compensate for the variation in torsional moment of the elastomeric members so that a predetermined tension can be maintained on the line (16) as the line is payed out and taken in from the tapered drum.

The apparatus comprises a heat source for directing pulsed infrared radiation onto a test surface; a scanner for scanning the test surface for infrared radiation being emitted therefrom; a detector for capturing said emitted radiation and converting it into a signal representative of the thermal characteristics of the surface; and video display apparatus for visually displaying the signal as a thermal map of the surface. The method comprises the steps irradiating a test surface and detecting temperature differentials that occur on the irradiated surface.

Abstract: Disclosed is an electric service entrance cable comprising parallel insulated conductors, helically covered by evenly distributed uninsulated conductors, covered by longitudinally wrapped polyester glassed-backed reinforcement tape bound by helically wrapped fiberglass strand and an outer covering.

Abstract: A method of fabricating articles from precipitation hardening aluminum alloys wherein the alloy is thermomechanically treated to control the characteristics of its microstructure before forging occurs in hot dies in an isothermal condition so that deformation occurs at a minimum strain rate. The forging temperature is above the solutionizing temperature of the alloy being forged.

Abstract: A method of and apparatus for detecting fuel leaks employing color variable indicators. The method comprises the steps of preparing and applying a water soluble non-staining indicator dye to a test surface, observing color changes indicative of hydrocarbon leaks and removing the indicator dye from the test surface. The apparatus comprises in combination means for preparing the indicator dye, means for applying the indicator dye to the test surface and means for removing the dye from the test surface. The indicator dye comprises a major portion of a dry inert mineral carrier from about 0.1 to about 5.0 weight percent of a direct dye which is non-staining on painted surfaces and which does not migrate into or penetrate polyurethane or epoxy resin base painted surfaces, and from about 0.1 to about 1.0 weight percent of a surfactant.

Abstract: Disclosed is an apparatus and method for automatically centering a metering pin in the pouring spout of a molten metal pouring pot.

Abstract: A compound angle disk cutting apparatus (11) comprises a stock feed and orienting mechanism (13) for feeding and orienting stock to be cut, a cut piece handling mechanism (15) for manipulating a workpiece cut from the stock, a cutting member (19) and a cutting member positioning mechanism (17). The various components of the apparatus (11) are configured such that any engagement of the cutting member (19) with a workpiece has a common center point of cut (21). The point of cut (21) is defined as the point of coincidence for the center of rotation of the stock workpiece, the center of vertical pivot of the cutting member (19), the center of horizontal pivot of the cutting member (19), the vertical-tiltable travel of the cutting member (19) as well as the transverse-rotatable travel of the cutting member (19).

Abstract: A housing (110) defines an enlarged central bore (162), from which protrudes a multi-conduit nipple (126). An elastomeric seal (128) flexibly joins the inner end of the nipple to the outer end of a respective sliding seat (116), the inner end of the seat being adapted to slide longitudinally within the central bore, whereby the elastomeric seal located is subjected to a shearing action as the nipple is pivotally deflected relative to the housing. One or more piston disks (174, 176) extend across the enlarged central bore so as to define a series of individual pressure chambers (182, 184, 186). A plurality of hollow cylindrical sleeves (188) extend through the disks, with the interior of each sleeve functioning as a continuation of a respective conduit through the connector.
