Abstract: U-Wp-1922 Gries WALL ANCHOR WITH SELF-DRILLING CAPABILITY     ABSTRACT OF THE DISCLOSURE            A unitary hollow plastic screw anchor which is capable of being hammered or otherwise driven into a hollow wall, with a weakened separation plane adjacent the entrance portion which is sufficiently strong to hold together during installation in the wall, and sufficiently weak to split apart when a screw is inserted into the installed anchor.          Features of the anchor include a generally cross-shaped entrance end for minimal penetration resistance, a generally rectangular interior with arcuate screw centering grooves, a single turn helix adjacent the wall-engaging flange thereof to start the screw, an internal step con-figuration to accommodate screws of varying diameter, and two longitudinal slots which compress during installation to further reduce penetration resistance.

Abstract: ABSTRACT OF THE DISCLOSURE         A latex of crosslinked silicone is prepared by emulsifying a vinyl endblocked polydiorganosiloxane and an organosilicon compound having silicon-bonded hydrogen atoms with water and surfactant, adding a platinum catalyst and then heating the emulsion to form the latex.  The water in the latex can be evaporated to provide an elastomer material.  Colloidal silica can be added to the latex to provide a product which is tougher.  Coating the latex on a substrate, such as a textile or paper, provides an elastomeric coated substrate, which provides water repellency, insulation and release properties to the substrate.

Abstract: ABSTRACT A wire matrix printer has a plurality of heads, each consisting of nine wires arranged in a slanting format The printer can be controlled to print Oreintal type characters such as Japanese by loading a wire image map of the characters into a memory.  The loading technique loads the memory in a slanted fashion corresponding to the slant of the print heads and reads from the memory in a bit column manner to correspond to the position of the various wires of the multihead print block.  The loading and unloading of the wire image memory is controlled by a pair of microprocessors operating respectively on different halves of the memory, such that at any given time, half of the memory is being loaded while the other half is being read from.  Thereafter, the memory is switched so that the loaded half is read and the previously read half is cleared and loaded with a new line of information.     Docket BC9-79-023

Abstract: SHEAR ACTION AND            COMPRESSION ENERGY ABSORBER                       ABSTRACT           An energy absorbing apparatus is provided to dissipate the energy of the impact force of a vehicle. A plurality of energy absorbing sheets are arranged in a stacked relation to resist the impact force and to thereby dissipate the energy of the force.  Each sheet has a honeycomb structure of hexagonal cells that are filled with a deformable material such as polyurethane foam and that are defined by walls of relatively rigid material.  In operation, an impact force is applied to the stack of energy absorbing sheets and each sheet is thereby caused to cut or shear into its abutting sheet so that at least a portion of the energy of the impact force is dissipated.  As the stacked sheets cut into one another, the energy of the force is further dissi-pated by the compression of the polyurethane foam of the sheets.

Imbedded within the surface of the housing that is located next to the skin of the human body  is  a protruding nodule.  This nodule is metallic and will normally be spherical in shape.  The nodule is to press against an acupuncture point of the human body.   An electrical conductor passes through the housing and is attached to the nodule.  This electrical conductor is connected to a source of electrical  energy.   This source of electrical energy is to transmit pulses of electrical energy in a preselected wave pattern to the nodule.  This source is electrically adjustable to vary the current to the nodule.

Abstract: Abstract of the Disclosure The rate at which glass batch is melted to a liquid state is improved by providing a series of depressions having sloped surfaces in the glass batch as the charging end of the furnace.  The sloped surfaces of the depression permit run-off of melted glass batch, thereby exposing the surface of fresh glass batch to the heat of the furnace.  Depressions in the glass batch are made by projecting periodically a plurality of hori-zontally spaced independently suspended and independently operable tapered pothole-producing members into the glass batch material and pushing the glass batch beneath the tapered member into the below the surface of the molten glass a distance about equal to the height of the glass batch blanket.  The action of the tapered member in producing the depression also provides a wave action to the body of molten glass in the vicinity of the charging end of the furnace, which enhances the rate of melting of glass batch materials.  Better coverage of the glass batch on the surface of the molten glass is also observed.

Abstract: OPTICAL TRIANGULATION APPARATUS & METHOD               ABSTRACT OF THE DISCLOSURE         The apparatus includes a light source for directing a measuring beam toward a workplace and a photo detector positioned to receive a portion of the measuring beam reflected from the workpiece.  A beam splitter is positioned between the light source and the workpiece to reflect a portion of the light source measuring beam to monitor photo detector.  The monitor photo detector receive the beam splitter reflected beam and provides an output signal representative of the position of the beam splitter  reflected beam, and hence, the position of the light source with respect to an idealized position.  In one embodiment, the photo detector develops a monitor output signal representative of the deviation between an Idealized Centerline and an Actual Centerline of the light source.  The monitor output signal may be employed for display purposes.  The monitor output signal may also be employed with positioning means to displace the light source from its actual position toward the ideal position so as to reduce the measurement error associated with the actual position of the light source.  Also, the monitor output signal may be employed to develop a compensating signal for reducing the measurement error associated with the actual position of the light source.

The plug may be inserted from a point where the line exits the earth.          Once the plug is inserted on the end of the heater element, the heater element is heated causing the plug to expand fitting it tightly inside of the line at or near the main.  The heater element may then be withdrawn, and the line may be cut adjacent the inserted plug.
