Abstract: The process of utilizing as a dog repellent, such as in a semiliquid slug bait or as a spray or as an impregnant or as a fertilizer component, material selected from the group consisting of methyl salicylate, birch oil, wintergreen oil, eucalyptus oil, pine oil and pine-needle oil.

Abstract: The casting wheel of a continuous casting machine is cooled by a conventional external spray cooling system, but the continuous band looped around the casting wheel to close a predetermined segment of it and thereby form a continuous moving mold cavity is not directly cooled. Rather, the band incorporates a layer of heat-insulative sheet material to deter heat transfer from molten metal introduced into the mold cavity through the band. The result is that the metal solidifies in a direction generally radially outward from the casting wheel toward the insulated band. Shrinkage of the metal occurs primarily adjacent to the band so as to eliminate or reduce internal shrinkage cracks and voids.

Abstract: Externally threaded opposite end portions of the bar of a barbell are insertable into the central apertures of cylindrical weights. Locking sleeves having manually retractable inward-projecting locking pins are fittable on the externally threaded bar end portions. With a locking pin in its projected position, the locking sleeve can be rotated like a conventional nut so as to advance toward or away from the weights. With the locking pin held in a retracted position, the locking sleeve can slide longitudinally in either direction along the threaded bar end portion without rotating.

Abstract: The leading end of tubular bag-making material is clamped between presser rods externally of the tubular material and a distender within the tubular material, and the clamping rods are moved upward to draw a bag-making length of material. The upper end of such length of material is spread by resilient wires to receive clamping means between them. The gripping rods are then withdrawn from the distender which falls freely through the bag-making material while the gripping rods are moved downward preparatory to gripping the next length of bag-making material and the bottom of the first length of material is closed and severed to complete a bag.

Abstract: Upright sidewall and end panels are bolted to a unitary base component having a treadmill so as to form a composite exercise tank. One end panel has a door of transparent sheet material with specialized hinges and locking mechanism to assure a leakproof fit. Water can be introduced into the tank to a desired level from a storage container, whereupon the treadmill is actuated for exercise or therapy. During use, water in the tank is recirculated through heating, cleaning and sanitizing equipment. After use, the water in the tank is emptied to the storage container and the user exits through the door.

Abstract: Conduits having the electric wiring for supplying power to lighting fixtures in an area classified as hazardous by reason of the presence of potentially explosive dust, vapor or gas have unobstructed interior passages for conveying nonexplosive gas under pressure from outside the hazardous area to each fixture. The pressure of gas in the conduit network can be monitored automatically and control mechanism can be provided to shut off the supply of electric power to the fixtures if the pressure falls below a predetermined pressure or a dangerous over-pressure condition occurs. At each fixture, the nonexplosive gas can be discharged along the face of the transparent fixture lens and/or along an exterior surface of the fixture housing to prevent build-up of potentially explosive agents and to cool the housing.

Abstract: Palatability of fish feed pellets is increased by coating preformed pellets with a coating of soft and flexible consistency that may be formed of alginate or guar gum set by calcium chloride solution or may incorporate gum tragacanth, pectin or gelatin.

Abstract: A specialized crusher has an upright compartment sized to receive an individual oil filter resting on a grate at the bottom. A crusher plate above the filter is guided for vertical sliding movement in the compartment and is moved up and down by a hydraulic jack. Downward movement of the crusher plate collapses the oil filter casing to compact condition and oil contained in it passes through the bottom grate into a spout leading to a receptacle. When a desired pressure has been reached, the jack automatically lifts the crusher plate and the collapsed casing can be removed for salvaging. All components of the apparatus are incorporated in a compact cabinet which can have a bottom drawer for the oil receptacle and a bin in which the collapsed casings can be collected.

Abstract: A normally horizontal base section supports the side section of a frame in upright position. A top section of the frame is normally positioned horizontally and has an open interior through which the lip of a bag can be inserted. The bag lip is wrapped downward over the outer periphery of the top section whereupon a rigid clamping ring is inserted over the top section to hold the bag lip in position. After filling of the bag, the clamping ring is removed, thereby releasing the lip of the bag for removal and, if desired, insertion of a new bag. When not in use, the base and top sections of the frame can be swung relative to the side section so as to extend parallel thereto for compact storage.

Abstract: In a planting device for attaching to an agricultural vehicle a planting slide is mounted on a frame for reciprocating sliding motion horizontally in the direction of travel of the vehicle under the influence of a hydraulically operable pressure cylinder. A support plate is mounted on the slide for sliding adjustment vertically, upwards and downwards, and a hollow, funnel-shaped planting spade is pivotally mounted on the support plate on an axis which extends transversely to the direction of travel of the vehicle.The tip of the spade is held in a forwardly directed pivoted rest position by means of a pre-stressed spring, but upon rearward pivotting of the spade, as occurs in operation when the support plate slides down so that the spade penetrates the ground, a control valve having a stem articulated to the spade activates the pressure cylinder to push the slide rearwards on the slide.

Abstract: A tunneling machine body carrying a rotary cutterhead can be advanced continuously by exerting advancing thrust forces on it, first by top and bottom bipods reacting from top and bottom anchor shoes, respectively, in anchored condition against the tunnel wall and alternately by side bipods exerting advancing force on the tunneling machine body and reacting from side anchor shoes set in anchored condition against the tunnel wall. The anchor shoes are floating relative to the tunneling machine body and connected to it only by the bipods producing the thrust for advancing the tunneling machine body. The top and bottom anchor shoes are directly connected by two pairs of upright fluid-pressure shoe-setting jacks extending chordwise between such shoes. The side anchor shoes are directly connected by two pairs of transverse fluid-pressure shoe-setting jacks extending chordwise between such shoes.
