Abstract: A toolhead having a spindle mounted in axially spaced bearings wherein one of the bearings is allowed to slide axially during dynamic effects on the bearings or thermal expansion and contraction of the spindle, the axial movement being made possible by the provision of rows of barrel-shaped rollers.

Abstract: Apparatus for feeding to a mold a plasticized synthetic material containing a foaming agent, the apparatus using a heated extruder and its associated transfer cylinder which emits the material in a thin stream by means of a nozzle.

Abstract: Remote shift for a vehicle in which a shift lever at a remote station operates transmission gears in a motor vehicle by operating a piston and valve which produce and control hydraulic pressure which operates actuating pistons at the gears.

Abstract: An injection carburetor having a rotatable control element for regulating air and fuel flow and adjustable needles for further controlling fuel flow at high speed and low speed, or an adjustable needle and a fuel tube having a T-shaped slot therein covered and uncovered by axial movement of a tubular control member.

Abstract: Driver for fasteners, wherein a slidable element contacts a work surface to allow fasteners to be driven, but otherwise inhibits the driving of fasteners.

Abstract: A liquid polymerizable material which may be used, for instance, for the coating of wood or other substrate, which material, when cured, is fire-resistant and protects the substrate. The material cures without application of heat and is formed from methyl methacrylate monomer, a hydroxy alkylacrylate or diacetone acrylamide monomer, a chlorinated hydrocarbon, an antimony compound, a zinc compound, a filler, and a catalyst-promoter system.

Abstract: A frame for holding an animal feeding bottle; the frame and bottle can be hung in the animal cage.

Abstract: The invention is concerned with an injection molding apparatus in which thermoplastic material mixed with an expanding agent is kept in a plastic state below the reaction temperature of the agent and is passed generally continuously through an inter-connecting passage to a transfer cylinder; by flowing through the passage, the mass is heated above the reaction temperature and the built-up pressure prevents foaming of the thermoplastic until it is injected into a mold.

Abstract: Switch actuator having a base adapted to be mounted adjacent a switch and an elongated lever hingedly mounted on the base to make it possible to operate the switch by means other than the fingers.

Abstract: Game racket having a rigid open cellular network defining the contact surface rather than the conventional stringing, the network and a frame being cast as a single unit and a resilient cylindrical grip being forced over a handle of rectangular cross section and the network consisting of plates whose greatest thickness is less than the width and length.

Abstract: A skating rink comprising a rigid wall forming the periphery of a closed area, and a sheet, spread over the area and the wall, to form a water container. The wall is formed of elongated flexible tube of plastic sheet which is placed in a peripheral configuration and then filled with space-filling, rigid material, either water, which is allowed to freeze, or formed-in-place plastic foam. The sheet is held in place either by tucking its edges under the wall or by wire clips which hold the sheet and wall together. A plastic foam blanket can be used to reduce puncturing of the wall.

Abstract: An intermediate semi-trailer unit which is towed by a highway tractor and tows a standard cargo semi-trailer. The standard trailer is attached to the intermediate trailer unit by a fifth wheel mounted on a portion of the chassis which permanently extends rearwardly beyond the cargo container of the intermediate trailer unit. The fifth wheel is positioned over or ahead of the rearmost bogie of the intermediate trailer unit. Means are provided to form, temporarily, a horizontal platform over the fifth wheel for the loading and unloading of the cargo container.

Abstract: Rolling mill for high production capacity and large bundle weights using one furnace followed by a roughing line and with separate intermediate- and finish-roll lines for each roll line.
