Abstract: Manually operated pincer mechanism for rapid shutoff of a pipeline that has developed a break or leak. The pincer mechanism is actuated by a manually operated hydraulic jack. The jaws are designed to shutoff small diameter steel pipe with the lower jaw in the upper position and with adapter members attached to both jaws with the lower jaw in the lower position is able to squeeze off plastic pipe up to a larger specified diameter. Removal of the plastic adapter jaws and with the lower jaw in the lower position permits booming down on patches for steel pipe up to a larger specified diameter for welding.

Abstract: Apparatus for handling large rolls of paper or spools of wire including a pair of outwardly extending arms, supported by air bearings, which straddle the roll or reel along the axis in a lower hemisphere. The roll is lifted upon inflation of the bearing and transported to its desired location. The parallel arms are adjustable toward and away from each other to accommodate rolls of varying diameters and may include stabilizing members for use with a reel in the event the arms are not of a sufficient length to extend beneath both flanges.

Abstract: The method includes the following steps: (1) a microsheet of glass is drawn from a glass melt; (2) a reflective layer, such as silver, is deposited on one surface of the microsheet; (3) a first flexible backing layer, such as fiberglass, is bonded to the reflective layer; (4) the combination of the microsheet with the reflective layer and the first backing layer is formed over a mandrel which is preferably in the form of a parabolic cylinder; and (5) a honeycombed layer, with a second fiberglass backing layer, is then bonded to the first backing layer. The product produced by the steps 1-5 is then cured so that it retains the desired configuration; i.e. parabolic-cylindrical, after it is removed from the mandrel.

Abstract: Reversible, elapse-time indicator utilizing two solid electrolyte cells in which current of one polarity is applied to one cell to cause silver ions to move from the positive electrode to the negative electrode. When all the ions have been removed from the positive electrode after a predetermined specific interval of time, the cell resistance increases to trigger an alarm such as a lamp. While the first cell is timing out, the second cell is being charged from a zero time value by a current of an opposite polarity equal to the time begun within the first cell. When the time interval has elapsed, the cells are reversed so that the second cell now becomes the timing device and the first cell is being recharged.

Abstract: The process includes the steps of (1) forming a pattern of indentations and adjacent boundary ridges in a base layer of glass which is heated to a temperature where it is formable but not flowing, (2) depositing electrically conducting first connecting elements on the upper surface of the base glass layer, with each first connecting element extending from an indentation to a point on an adjacent ridge, (3) positioning a solar cell into each indentation in the base glass layer in such a manner that the lower surface of the solar cell comes in electrical contact with one end of a first connecting element, (4) depositing electrically conducting second connecting elements which extend between the end of the first connecting elements on a ridge to the top surface of a solar cell in an adjacent indentation, and (5) forming a top glass layer which is in intimate contact with the product of steps 1-4.

Abstract: A game involving strategy, perception and decision making wherein the board comprises a base member having a plurality of horizontally slidable members having a plurality of uniformly spaced marker receiving positions. Each player has a definitive number of markers and each turn is initiated by a roll of a pair of dice or other random selection means. Upon the completion of a roll or turn, a player will place a marker upon any one of the slides in a receiving position corresponding to indicia shown upon his side of the board. A score is tabulated at the end of a turn by counting the number of markers belonging to the scoring player in a line either perpendicular to the direction of slide movement or diagonally across the board. One of the "slides" may be fixed to establish a stable base for building scores but will still be a part of the scoring procedure.

Abstract: The characters are produced electronically through the implementation of character instructions which are stored in a memory in the form of a series of binary words. Each binary word is an instruction for producing a single straight-line portion, or stroke, of a complete character. Each such instruction word contains a count portion, which identifies the length of the stroke, a slope portion, which identifies the slope of the stroke, and a visibility portion, which identifies the visibility of the stroke. The character generator includes a counter which is preset to the amount of the count portion of each instruction word. The counter is counted down by a clock operating at a predetermined frequency. The slope portion of each instruction word is converted by a decoder into its respective X and Y component parts. These X and Y components are then applied to separate data channels which include adder/subtractor units under the control of the clock.

Abstract: A shearing interferometer which includes a laser source, a reflector structure and an interference detection system. The reflector structure is mounted on an object, the angle of which, relative to a reference line, is to be determined. The reflector structure includes a transmission hologram and a retroreflector, wherein the transmission hologram is so constructed and positioned relative to the retroreflector that two or more parallel beams of preselected separation (shear) are produced for each incident beam. The difference in optical path length of a given pair of the parallel beams will vary depending on the object angle, and hence, the interference effect of the given pair of parallel beams will also vary in accordance with object angle. The interference effect is summed at a detector, and then analyzed by a tracking circuit to determine object angle.

Abstract: The structure includes a base surface which is divided up into a plurality of relatively narrow, substantially rectangular portions which are arranged in a substantially grid-like pattern. Each portion includes a putting green surface region which includes a hole adapted to receive a conventional golf ball. Nearly all of the portions include a combination of one or more of the following surface regions in addition to the putting green surface region: a water hazard region, a sand hazard region, a rough region, and a fairway region. Obstacles may be present in one or more portions and the terrain of the portions may vary. A starting area is provided on a selected one of the surface regions of each portion.

Abstract: A circular saw blade having mounted on the outer circumference thereof a plurality of spaced conical teeth in lobes separated by aerodynamically designed gullets. The teeth are integral portions of elongated shafts and the axis of the elongated shaft is mounted at a slight angle from the perpendicular to a radius of the blade itself. The gullet is of a configuration wherein the turbulence created by the blade moving rapidly through the air generates an outward flow of air removing the particulate waste generated thereby eliminating clogging and the resultant friction.

Abstract: The graphic generator includes a coding section which produces a series of data words which describe the input data to be displayed in terms of change of slope over time. Each data word contains enough information to describe one line on a display raster. The data is displayed as a three variable image, one variable being in the horizontal dimension of the raster, another variable being in the vertical dimension of the raster, the other variable being the intensity information of the display, which is superimposed on the vertical axis of the display through a summation of the vertical deflection circuit. The lines of the raster may be rotated with the superimposed intensity information being held constant as a reference, so that the view of the image appears to change, thus providing a three dimensional view of the image.

Abstract: Diesel fuel injection system in which a standing high-pressure wave is maintained in the common rail and which utilizes injectors which function as gates or valves. Electronic controls sensitive to engine demands based on speed and load electronically control the injectors to vary both moment and duration of fuel injection time. Input signals, as determined by engine speed by way of the distributor, vary the injection timing according to an advance curve at the distributor correlated to piston position. Duration of the injection cycle (quantity of fuel injected) is controlled electronically and variably in relation to throttle position.

Abstract: In one application, the apparatus is used with unstable laser resonators which include a gain region defined by a concave mirror and a convex mirror. The apparatus includes a spectral line selection medium, such as a multiple band pass filter or a multiple diffraction grating, which is located so that the laser beam directed out of the laser gain region impinges thereon. A retroreflector is positioned so that the spectral lines selected by the line selection medium are reflected back into the laser gain region along the propagation path of the incident beam, resulting in a lockup of the laser at the selected spectral lines.

Abstract: An extendible probe comprising an electrode and a body having two parts which cooperate to clamp the electrode in a desired position. The electrode comprises an elongated length of small diameter, electrically conducting, non-corrosive material which is electrically insulated except for the tip of one end, which is exposed and formed to a point. The two-part body has a longitudinal opening therethrough, which receives the electrode. The front part of the body, referred to as the tip, includes a tapered collett which extends away from the rear end thereof and which is compressed under pressure against the electrode, which passes therethrough. The rear part of the body, referred to as the barrel, overlays the collett and threadably engages the tip of the body. This arrangement permits controlled longitudinal movement of the barrel relative to the tip of the body.

Abstract: An electrode which is adapted to be used on a human body and suited for transmitting electrical impulses into the body.

An electrically conducting snap fastener is embedded in the electrode and is in electrical contact with the screen. The metal fastener provides a terminal connection for a conventional electrical lead, which carries the electrical impulses from a source thereof to the electrode.

Abstract: An otherwise conventional soccer shoe having two visually distinctive areas located in two regions of the shoe where proper contact with a soccer ball should be made. The first area covers a substantial part of the toe region of the shoe and the second area covers a substantial part of the instep sidewall region of the shoe. The two areas are visually distinctive from the remainder of the shoe.

Abstract: The nozzle and laser channel walls for a supersonic electrical discharge gas laser are formed from fully contoured single pieces of dielectric material. The axially symmetric, two-dimensional wall contours of the combined nozzle and laser channel describe a continuous extension of the subsonic flow plenum, into which the gas is initially introduced, and which is located upstream of the combined nozzle-laser channel. A high precision portion of the contour of the combined nozzle-laser channel extends from a beginning point in the nozzle inlet region near the throat to a termination point which is beyond the nozzle exit plane a distance equal to approximately one-half of the nozzle exit height. The high precision portion is a region of continuous curvature supersonic expansion.

Abstract: The article is a combination of a protective pad, a cover element and two elastic strips. The protective pad is somewhat wider than it is long. The top and bottom edges of the pad are substantially straight, while the central portion of each side edge is cutaway, leaving two protrusions at the opposite ends of each side edge. The cutaway opening in each side edge extends a substantial distance into the pad, and a further keyhole-shaped opening, central of the cutaway opening, extends even further inwardly of the pad. The pad is covered with the stretchable fabric cover element, which follows generally the outline of the pad. The two strips of elastic connect the opposed side edges of the pad-cover combination at each end thereof, with the elastic strips being sufficiently short that they tend to draw the sides of the pad-cover combination toward each other, thereby curving the surface of the combination so that it will conform to the user's limb.

Abstract: The apparatus is adapted to fit on the lower surface of conventional toilet seats, and comprises (1) a base element, (2) a support element, including handle, rotatably secured to the base element, (3) an elongated fluid carrying arm extending from the support, and (4) a sprayhead. By rotating the handle, the sprayhead moves through a relatively shallow arc from a retracted position adjacent the lower surface of the seat at the rear thereof through an operative path beneath the opening in the seat. The axis of rotation of the support element and the configuration of the fluid-carrying arm are such that the focal point of the arc of the sprayhead is several inches above the plane of the seat.
