Abstract: The system for removing the soil gas from the ground surrounding the building structure, includes a clean-out pipe, an air duct system, and a fan. The clean-out pipes are installed inside the building structure, accessible from the ground level and near junctions between the interconnecting pipes and the drain tile. The air duct system is securable to a clean-out pipe, and the fan is installed inside the air duct system. The air duct system is disconnected from the clean-out pipe during the cleaning of the drain tile system. The pressurized fluid projecting through the tip of the rocket nozzle, removes any obstructions in the drain tile, and the pressurized fluid projecting rearward from the nozzle, propels the rocket nozzle through the drain tile system. The air duct system is then connected to the clean-out pipe. The venting of air away from the drain tile system creates a negative pressure, which draws the soil gas into the porous drain tile.

Abstract: While chain tensioners are used with chains on the engine of a motor vehicle, conventional blade spring configurations do not apply consistent forces throughout the life of the chain. The chain tensioner comprises two blade springs mechanically interlocked within a shoe, the shoe being adapted to contact the chain of the motor vehicle. The two blade springs each have a minimal form radius that is substantially smaller than the minimal form radius of a single blade spring, the single blade spring being otherwise identical to the two blade springs, and the thickness of the single blade spring being the same as the combined thickness of the two blade springs.

Abstract: This is a new apparatus and method for cleaning debris from the inside of a foundation drain tile, the drain tile being in the immediate proximity of the perimeter of a building structure. A rocket nozzle which is in fluid communication with flexible tubing and a high pressure water supply, and a foot pedal control valve is used for starting and stopping the fluid flow. An opening in the tip of the nozzle enables pressurized water to be discharged through the tip in a forward direction. At least two apertures are disposed along a nozzle recess. The tubing is secured to the nozzle and is in fluid communication with the nozzle. An on-off foot pedal control valve is used to start and stop the water flow into the tubing and into the nozzle. As pressurized water is supplied to the nozzle and projected through the apertures, the nozzle is propelled in a forward direction through the drain tile.

Abstract: A device for sterile disposal of a device used to withdraw or inject fluids from or into the body comprising a tubular sheath disposed in a rolled-up fashion around the body fluid device proximate one end thereof. The length of the sheath is great enough to permit the sheath, when unrolled, to extend beyond the end of the body fluid device and for a sufficient distance to permit ready enclosure thereof and subsequent sealing off of the contents of the sheath. A method for using the device is also disclosed. The device is particularly useful in combination with a catheter of conventional design.

Abstract: A dust-proof seal has a metal plate attached to a slider and a rubber member adhered to the metal plate. The metal plate has an opening to allow a guide rail to pass therethrough, and the rubber member has protrusion protruding inwardly beyond the inner edge of the opening of the metal plate. A pressing member defined by a wire spring is mounted in a channel formed in the rubber member at the periphery of the lip portions and exerts a spring force to press the lip portions against the surface of the guide rail to thereby bring the lip portions elastically in contact with the guide surface to wipe out any dust deposited thereon.

Abstract: The invention involves an inexpensive, rugged, flexible, composite plastic backlight panel that provides an even heat distribution across the entire surface of the backlight panel for a convertible top of a vehicle. Two wires are connected to the car battery. A series of conductive members are each in electrical engagement with each of the wires, forming a closed loop electric circuit. The conductive members are printed onto one of the laminates, forming an interlayer thereon. An inner transparent plastic laminate, and an outer transparent plastic laminate are sandwiched around one end of each of the wires, and the interlayer. The laminates including the wires and members are bonded together and the resulting panel is secured to the convertible top thereby forming the backlight panel. When the circuit is energized, the electrical energy is converted into thermal energy that is transmitted to the outer laminate.

Abstract: A hull form for a vessel which hull form is deep-Vee based and is constructed and arranged for use in a displacement mode. The hull includes a bow section which incorporates a plurality of lateral grooves or, alternatively, a single lateral formation and which extends below the base or datum line of the hull in a streamlined teardrop configuration. Preferably, the hull has deep-Vee deadrise angles (1) whose magnitudes in the region of the transom of the hull are not less than 20.degree.. The surfaces extending between the keel and the water line length are non-planar and have developable convex and concave geometry, all buttock lines of the hull having a negative inclination of between substantially 1/2.degree. and substantially 4.degree.. The invention enables the known advantages of deep-Vee based hull forms to be used in displacement mode vessels having relatively large displacements where, heretofore, "round-bilge" hull forms very greatly predominated.

Abstract: A thermal wave imaging apparatus generates a real time image of the surface and subsurface of an opaque solid object. A.C. electrical signals indicative of the configuration of the surface and subsurface of the object which are generated during a thermal wave scan of the object by a first heating beam which generates a localized temperature gradient on the object and a deflectable second probe beam heating beam, which deflection is detected by a detection device mounted adjacent to the object, are stored in an image memory under the control of a central processor. A refresh counter generates sequential, incremental signals used to control the X and Y axis deflection of a display monitor. Such signals also address the image memory and generate output data controlling the intensity of the display point at each generated X and Y axis deflection point.

Abstract: This new technique for stacking multiply folded optical paths in an extended region of a laser resonator within a gaseous medium. The path segments are connected together by a set of mirrors located along the resonator perimeter. Moreover, this invention involves a system of stacking unit tiles, each minim containing a multiply folded path, into larger domains. A multiplicity of mirrors is located in the laser resonator around the perimeter of stacked minims. A longer optical path is achieved without a corresponding increase in the number of folding elements, by stacking the minims together and thereby extending the length of the folding elements. The resulting domains fully cover the plane with a grid of evenly spaced and intersecting optical paths. The laser resonator can be used in either a laser oscillator or amplifier, and in either pulsed or continuous wave mode.

Abstract: A cranking fuel control method and apparatus for combustion engines. The method includes the steps of delaying the injection of fuel to the engine until one or more of the operating parameters of the engine, such as the engine rotational speed, the crankshaft rotation angle or the cylinder gas combustion pressure has reached a predetermined value. The fuel is then injected into the cylinder(s) at the required quantity for optimum starting of the engine. The method and apparatus can be used in fuel pumps with mechanical governors or with engines having electronic fuel controls.
