Abstract: A fluid control valve has a cylindrical body member with inlet and outlet passages in spaced relation to one another. A control stem is movably positioned in a control chamber formed by the body member. A split expandable sleeve in the control chamber is movable by the control stem to provide overall volume control.

Abstract: A hunting arrow has a shaft with a steel tip and a game penetrating two-part fletch. The first parts of the fletch are made of thin flexible razor sharpened steel that are in alignment with the remaining parts of the fletch which are usually flexible plastic or feathers. The razor sharpened steel parts of the fletch insure a large initial wound and faster kill.

Abstract: A mixing valve has a cylindrical body member with inlet and outlet passages in spaced relation to one another. A control stem is movably positioned within the body member which defines a mixing chamber. A split expandable sleeve in the chamber is movable by the control stem to provide for regulation of outlet fluid temperature through mixing. Overall volume control is achieved by longitudinal movement of the control stem and dual valving action.

Abstract: An inflatable dock seal for closing the area around a dock opening in a wall with respect to a railway car or the like is secured to said wall by devices comprising uninflated tubular members attached to said inflatable dock seal and rigid structural members positioned in said uninflated tubular members so as to extend longitudinally of the sections of the inflatable dock seal. Clamps are affixed to the wall in which the dock opening is located and adjacent thereto and the uninflated tubular members with their rigid structural members are engaged by said clamps to secure the dock seal to the building about the dock opening therein.

Abstract: A runner for hot metal as from a blast furnace is formed of a series of interconnected modular units which are prefabricated from consumable combustible, and/or disintegrable materials of desired densities resulting in a calculated exposure life determined by the amount, the time and the temperature of the molten metal handled by the runners. The modular runners are formed of a mixture including clay, wood chips, paper pulp and/or any combustible material, which when mixed or blended with any refractory produces a consumable, disintegrating combustible mixture that has a disintegration or combustion rate dictated by the density of the compaction of the material in the finished product.

Abstract: A lighted coaster for drinks provides a base with a light source, a reflector adjacent the light source and a translucent supporting surface upon which a glass can be placed.

Abstract: An extensible room for travel trailers having a floor, walls, and roof section is arranged for sideward movement into and out of an opening in one of the trailer walls, the extensible room is suspended from overhead telescopic supporting frames and a drive assembly for moving the extensible room is provided.

Abstract: A process of treating coke oven doors and jambs with a material containing micro micron particles of graphite in a liquid carrier is described that forms a penetrating lubricating adhesive coating on the coke oven doors and jambs which acts to prevent leakage of tar and other coke by-products as heretofore common in the art and the resultant inability of maintaining a sealing relation between the doors and jambs.

Abstract: A vehicle sun visor is provided with several generally rectangular visor extensions, each of which is formed of a transparent shaded synthetic resin material, the shading comprising extremely fine evenly dispersed magnetizable powder, such as ALNICO, or iron. A section of the material after the magnetizable powder has been magnetized by electromagnetic means is attached to the conventional sun visor and the additional generally rectangular sections are adjustably positioned thereon or one upon another as desired to effect a desirable sun screen and/or glare shield for the driver of the vehicle.

Abstract: A tennis racket construction comprising a frame having an ovaloid head portion terminating in a pair of closely spaced parallel extensions which are adapted to receive a handle with the head portion of the frame being defined by the oppositely curving portions of the frame. A flexible metal throat is positioned between the oppositely curving portions of the frame to complete the ovaloid shape of the head of the racket and to provide the sole support for adjoining strings attached thereto.

Abstract: A corner wedging consumable hot top for ingot molds is formed of four side board sections and four corner wedges made of a combustible consumable material capable of being wedged in opposed relation within an ingot mold so that the hot top formed thereby conforms with the cavity shape in the ingot mold and when ignited by the molten metal poured therein supplies heat to maintain a pool of molten metal as necessary for filling cracks and pipes in the cooling ingot.

Abstract: A self-adjusting easy on tire chain for use on automotive or similar vehicle tires consists of a chain having a spacing and alignment bar with a fastener for securing the chain in the proper position on a tire.

Abstract: A floor or roof drain fitting includes a flanged tubular member for positioning in an opening to form a drain structure. A sleeve is engaged about the tubular member such as by threaded engagement therewith with the upper portion of the sleeve being of considerably larger diameter and provided with a plurality of circumferentially spaced finger-like sections which are frangible. Tubular members may thus be clampingly secured in an opening in a floor or roof to form a water tight drain fitting.

Abstract: A shotgun butt cup comprises an elongated cup-shaped pad for receiving the butt portion of a shotgun or the like stock. The butt cup is secured to a strap for placement around the shoulder of the user so that the same gun placement and alignment can be maintained on each shot.

Abstract: A knee brace designed to help stabilize the knee ligaments and provide support for the knee joint, comprises a tubular elastic sheath placed over the knee, a strap attached midway between its ends to the sheath which wraps around the sheath and crosses behind the knee cap in a crisscross manner to achieve the added support of the knee ligaments. The knee brace contains no supportive rigid components and does not impede normal flexability of the knee joint. An apertured disc is positioned on the sheath by the strap which applies pressure on it to relieve the pain associated with Osgood-Schlaughter disease.

Abstract: An improved ascension pipe elbow lid for coke ovens forms a communication means between the coke oven and the volatile products collecting main. The improved structure incorporates a vent which is sealed to prevent the escape of pollutants into the atmosphere.
