The device involves modified male and female contoured members such as complemental ball and socket members which can be easily brought together into mating engagement by a uniform cable member passed through continuous openings in both contoured male and female members and is capable of drawing together the paired vehicles into precise alignment and positively seating the coupled members into mating relation with minimal physical effort.

Abstract: An animal restraining device especially useful for valuable and treasured dogs comprising an elongated flexible main cable member with each end having doubled-over portions joined to itself, each doubled-over portion having a sidearm end extension member fixedly joined to the doubled portion to constitute a bifurcated end assembly, and four swivel snap connectors joined to each of the four extremities of the two end assemblies for doubly safe connection to the animal and to an anchoring point. The similar end assemblies permit use of the device reversibly in varied arrangements.

Abstract: This invention relates to a process and apparatus for treating molten aluminum prior to casting by adding a hydrogen-containing treating gas to the atmosphere over the molten aluminum during melting. A preferred treating gas is finely-atomized water vapor which is added to the fuel-air mixture to be delivered to burners to obtain a disassociation of water vapor into hydrogen and oxygen. The added hydrogen satisfies the affinity of molten aluminum for hydrogen, the addition being controlled to near the saturation point temperature of hydrogen within the molten aluminum. Improved casting properties are obtained in the molded parts which have smaller grain refinement and greater dispersion of shrinkage on cooling to solidification. The treating gas may also consist of hydrogen gas or ammonia gas, the hydrogen being supplied over the molter aluminum when heated to a temperature ranging from about 1200.degree. F. to 1480.degree. F.

Abstract: This invention relates to rigid molded tong inserts for take-out tong members for handling hot glass articles and the like immediately following their molding. The inserts are utilized in pairs being heat and wear-resistant with exposed metallic working surfaces substantially surrounded by molded thermoset-hardened heat-cured insulating plastic material. The inserts have essentially flat parallel surfaces with a metallic reinforcing member integrally molded therewithin, the metallic reinforcing member having a semi-circular shaped exposed working surface adapted to directly contacting the finish area of the hot glass articles and a diametrically-disposed exposed flanged working surface adapted to non-wearing support within a retaining metallic take-out tong member.

Abstract: This invention relates to a combined vehicle-mounted carrier and dispenser for a cylindrical hay bale of substantial size and weight. An elongated finger-support member is pivotally mounted on the bed of a pick-up truck, a tractor hitch or other vehicle. The finger support member is T-shaped to retain a plurality of movable support fingers in cantilevered relation to penetrate and engage the bale. The finger support member is pivotally attached to a base member which is mounted on the truck bed. A power winch is located on said base member having a cable connected to the free end of the central arm member of the T-shaped finger support member. Tensioning means comprising a pair of aligned leaf springs is mounted between said pivotal finger support member and said fixed base member to maintain continuous tension on the cable and thus prevent any loose unwinding or unraveling of the cable on the power winch.

Abstract: This invention relates to a method of strengthening glass articles and, more specifically, hollow glass containers such as jars for containing foodstuffs. The invention is directed to a method wherein the hollow glass container is surrounded at its heel and bearing surfaces with a thin continuous frangible coating of a polymeric resin such as an epoxy resin. The resin is cured into a frangible thermoset condition to resist thermal shock breakage; however, any breakage of the container at its coated area will result in disruption of the surrounding coating evidencing such breakage. The coating is extremely thin and continuous, and readily applied, and may be used in combination with a foamed thermoplastic tubular sleeve snugly conforming to the body portion of the container. The conforming sleeve serves as a label and to provide an insulating jacket for handling the container when its contents are heated, such as in a microwave oven.

Abstract: An extruder apparatus control system wherein a temperature corresponding to that of the extrusion material is sensed at each of a series of zones extending along the apparatus extrusion chamber and also the velocity of the apparatus ram. The control system includes a command device for providing operating commands corresponding to a selected operating mode of the apparatus and a velocity command corresponding to a desired velocity of the ram for the selected operating mode. From these operating commands a controller establishes for a selected operating mode, a series of temperature set points, each corresponding to the desired temperature at one of the series of zones and from the velocity command, a velocity set point representing the desired velocity. Thereafter, the control system compares the set points with the sensed values and makes corrections as required to achieve and maintain an equality between them.

Abstract: There is disclosed a gaseous discharge display device having a plurality of gaseous discharge sites and at least one active, working dielectric surface exposed to the gas discharge at each discharge site. The active gas contacting dielectric surface is coated with a protective film in an amount sufficient to prevent the formation of undesirable contaminants on the active dielectric surface, particularly during the manufacture of the device. After the complete assembly and gas filling of the device, the protective film is removed from the vicinity of each gas discharge site by the application of a gas discharge voltage at the site sufficient to sputter the protective film away from the discharge site without sputtering the active dielectric surface.

Abstract: A rimless face panel is mounted on a funnel-shadow mask color selection device subassembly for a color television picture tube construction by indexing means establishing a unique positional relationship between the face panel and the mask.
