Abstract: MODULAR SCREW ANCHOR HAVING LEAD POINT      NON-INTEGRAL WITH HELIX PLATE     Abstract of the Disclosure A high strength, modular screw anchor is disclosed which exhibits enhanced failure resistance notwithstanding use of-essentially the same amount of material as conventional anchors, and which can be installed using existing installation equipment.  The preferred screw anchors of the invention include an elongated rod having one or more separate, specialized anchor members supported thereon, and an improved, obliquely oriented, beveled earth-penetrating lead to facilitate installation, particularly in rocky soils.  The anchor member includes a tubular, central, rod-receiving hub presenting a polygonal in cross-section bore therethrough, and an outwardly extending helical blade affixed to and coaxial with the hub.  In installation procedures the anchor rod is passed through the hub bore and the anchor member is operably coupled to the rod (as by resting it atop an outwardly extending shoulder provided on the rod); the tubular shank of a standard anchor wrench is next telescoped over the anchor rod and inserted into the hub bore such that a driving connection is established between the rod, shank and anchor member.  Axial rotation of the wrench thus effects corresponding rotation of the screw anchor for installation purposes.  The earth-penetrating lead of the screw anchor may be formed integrally with the major portion of the rod, or threaded thereon; in the latter case the overall length of the rod can be adjusted as desired.  The (Docket No. 16993) modular nature of the screw anchors hereof permits stocking of only a relatively few standard compo-nents which can be used as needed in the field to achieve a desired anchor configuration.

Abstract: VARIABLE VOLUME HYDRAULIC PUMP     ABSTRACT OF THE DISCLOSURE     A variable volume pump for satisfying the requirements of a hydraulic system while absorbing excess fluid volume when the full volume of fluid displacement from the pump is not required by the hydraulic system. The pump includes one or more lines of reciprocable pistons mounted radially around a crankshaft. The rotation of the crankshaft results in centrifugal flow of fluid through crankpin apertures for filling the pistons. Each piston includes a cylindrical tube portion which is slidably movable within a metering sleeve. The metering sleeve is spring biased towards a position for covering metering ports that are located around the periphery of the piston tube portion. When the fluid pressure in the hydraulic system acting on a metering sleeve abutment area exceeds the force of the metering sleeve spring, the metering sleeve moves thereby uncovering the piston metering ports. The movement of the metering sleeve permits the piston to travel an equal distance with its metering ports open. This results in the displacement of a fluid volume to a low pressure cavity within the pump until the piston metering ports are again closed by the metering sleeve. Thus, fluid flow from the pump is reduced in proportion to increased system pressure until a maximum desired output pressure is reached with minimum fluid flow.

Abstract: Video Overlay System Having Interactive Color Addressing Abstract Apparatus and method are disclosed for selecting colors for presentation in a display device such as a CRT. The apparatus includes a pair of video memories that store picture element (pixel) data for presentation at the same location of the display device.  A color map, or video look-up table, stores digitally encoded colors that are provided at its output in response to a digital input address.  The digital input address is partioned into several portions.  Pixel data from the first video memory supplies one portion of the digital input address while pixel data from the second video memory supplies another.          Neither video memory has priority in selecting the color presented on the video display although the color map is programmable to give effective priority to either one.         The digital address is further partioned into a third portion to thereby define the color map as a plurality of segments.  A data processor selects which segment of the color map is to be addressed by the video memories thereby changing priority and/or color palettes without alteration of the pixel data or the need to reprogram a segment of the color map.

Abstract: LIGHTING UNIT WITH IMPROVED CONTROL SEQUENCE              ABSTRACT OF THE DISCLOSURE      An energy efficient lighting unit is described designed for functional similarity to the incandescent light used in the home.  The lighting unit utilizes a metal vapor arc lamp as the main source of light supplemented by a standby filamentary light source.          The lighting unit includes means for converting 60 hertz ac to dc, and a dc energized operating network contain-ing a three transistor switch.  The transistor switch is used to provide dc and low frequency (120 Hz) ener-gization to the filament, and high frequency energiza-tion for both  filament and arc lamp.  The high frequency energization, which starts and transitions the arc lamp, is discontinued after the arc lamp is started.  In the final run state, the arc lamp, which is serially connected with the filament across the dc supply, is ballasted by the filament.  The transistor switch is controlled in its operation by control logic provided by an integrated circuit, which provides a complex control sequence, optimized for minimum electromagnetic interference for normal starts, "hot restarts", and a failure state, called "End of Life" in which starting attempts are dis-continued.

Abstract: CURLING SLIDER CONSTRUCTION           ABSTRACT OF THE DISCLOSURE         Conventional curling sliders often include trays-verse bars, or permanently situated slider strips adhesive-ly secured to the shoe sole or to a slider plate which in turn is secured to the sole.  When sliding, the instep area of the shoe bends severely and the strips or bars therefore reduce the flexibility of the instep area making the bending action stiff and somewhat inflexible as well as causing problems of adhesion to the strips or bars.  In the present invention, a plurality of relatively hard plas-tic buttons are provided which may be adhesively secured by the wearer, where desired and in a variety of shapes and patterns. The junction between the ice engaging surface and the walls of the buttons provides a smooth transition area thus preventing any scratching and scoring of the ice surface.
