Abstract: A method for manufacturing boots of rubber or the like wherein the successive boot building operations are carried out on lasts carried by a movable conveyor indexed to and through stations spaced along a line. An elastic sock is mounted on each last at the first station, an adhesive or a chemical reactant such as a coagulant solution are applied to the sock, latex dip coatings are applied, and binding, foxing, toe caps, insulation and the like applied before vulcanization and final lacquer spraying and trimming at indexed stations.

Abstract: A water reservoir tank storing a primary body of water for release to a toilet bowl for flushing is associated with a pressure tank that stores a minor amount of water at a pressure considerably higher than that of the primary body and is discharged during flushing to join the water released from the reservoir tank and impart increased overall energy to the water in the bowl. A predetermined time delay is introduced between start of the flushing action and discharge of water from the pressure tank. The pressure tank is automatically discharged and recharged during each flushing cycle.

Abstract: A method for the manufacture of a force transducer consisting of a base carrying a stud which carries a set of shear sensitive elements, each having a seismic or force transmitting mass attached to it, the masses being fixed to shear sensitive elements fixed to the stud by means of a cylindrical spring clip surrounding the force transmitting masses and supplying elastic force through the elements to be fixed to the stud, the method involving cutting of slots which are parallel to the axis of the rod with a depth greater than the height of the shear sensitive elements, insertion of shear sensitive elements into the slots, pressing of a cylindrical spring clip around the slotted part of the rod, and cutting radially into the rod so as to remove the material making up the bottom of said slots.

Abstract: A novel forced air fireplace heating unit in which a plenum for delivering heated air to a room or other space overlies a double jacketed furnace and communicates with an air heating space between the furnace's jackets, whereby air introduced into the heating space by convection or by a blower flows through the heating space and then through the plenum for delivery to the area to be heated.

Abstract: A method of using fluorinated hydrocarbons as a carrier to convey mined coal to a separation station. The carrier acts as a parting liquid for beneficiating the coal. The carrier is recovered and returned to the mine for conveying more coal. Some of the returned carrier may be used at the mining face as a dust suppressant. Ash from burning the coal may be returned with the carrier where it is disposed of as waste material.

Abstract: Coal is separated in a gravity separator using a fluorinated hydrocarbon parting liquid. The cleaned coal is burned and the ash mixed with recovered parting liquid and returned to the gravity separator. Additives may be dispersed in the parting liquid to alter the physical and/or chemical characteristics of the products. The additive may be a dustproofing or a waterproofing agent.

Abstract: A device or system for cleaning windshields, headlamp lenses, rear view mirrors, reflector means, or the like of a vehicle. The system is installed in the vehicle, preferably in the engine compartment, and includes a liquid container, a conduit from the container to a steam generator, including a pump and a stop valve downstream of the pump to prevent return flow of liquid from the steam generator to the container. Engine exhaust heat or an electric heater is used for heating the steam generator, and an outlet conduit with nozzles direct steam from the generator to the vehicle parts to be cleaned. The system has a shunt conduit from the liquid supply bypassing the steam generator and connected to the outlet conduit downstream of the steam generator and steam from the generator mixes with the liquid from the shunt conduit and the mixture advances and flows out to the vehicle part or parts to be cleaned.

Abstract: A component unit for excavating, compacting and loading material on a horizontal or sloping surface. A carrier beam pivotal in the horizontal and vertical plane carries via a plurality of elastic members an excavating blade and further an amplitude limiter between said beam and said blade. The amplitude limiter comprises a sliding body carried by said blade and provided with a top sliding surface and a side sliding surface having an angle of preferably 135.degree. to the top sliding surface. The carrier beam carries partly a top block above and adjustable in relation to the top sliding surface partly a stop member portion along and on a small distance from the side sliding surface.

Abstract: A dishwasher water distribution system with a lower wash arm assembly and an upper wash tower, the wash arm assembly including a rotatable wash arm releasably fastened to a unitary distributor structure, the entire wash arm assembly with its distributor being telescoped on a lower stationary water inlet component and rotated and lifted by water pressure to sealingly engage and rotate the wash tower, the wash arm assembly being guided in its vertical shift by a bearing rod about which the entire wash arm assembly, as well as the wash tower, rotates. The lower wash arm assembly can be lifted from the bearing pin and the wash arm can be removed from the distributor by releasing clips integral with the unitary distributor structure.

Abstract: A fuel-air supply system for a combustion engine wherein unmixed supplies of liquid fuel and combustion air are heated and after heating are bypassed around the engine's carburetor for delivery to the engine in place of the fuel air mixture from the carburetor when the temperature of the liquid fuel being heated rises to a pre-selected temperature.

Abstract: Methods of and apparatus for cleaning coal in which fluorochlorocarbons are used as parting liquids. Various novel techniques, components, and combinations thereof are employed to maximize efficiency; to minimize costs and adverse environmental impacts; to make it possible to recover coal of a character which has heretofore been economically unrecoverable; to produce a superior product; and to reach other worthwhile goals.

Abstract: A gas turbine engine having a turbine with internally cooled, stationary nozzles, a rotor with internally cooled blades, and systems for supplying air to the nozzles and rotor and for cooling the nozzle case.

Abstract: A device for transfer of fresh air or air mixed with gases, vapors, smaller particles etc. in one or other direction between a stationary place and a moving place. A stationary elongated box is in communication with the stationary place and has a slot in its longitudinal direction and said slot closeable by a tightening band bearing on contact surfaces at each side of the slot and on the outside of the box. A hollow connection body projects through and is movable along said slot and is in communication with the moving place. Said connection body is provided with slide shoe or shoes in the slot and carries a press roller at each end of the slide shoe or at each slide shoe pressing the band against said contact surfaces and backing rollers lifting the band from engagement with the contact surfaces.

Abstract: A golf ball wherein an elastomeric spherical core is formed with a series of narrow shallow surface channels each lying on great circles passing through opposite pole areas, and similar hemispherical cover shells are compression molded upon the core and joined along a transverse seam lying in a plane that intersects all of the great circles, preferably at about 90.degree..

Abstract: Processes for making polymeric compositions which have methacrylic and/or acrylic chains grafted onto a copolymerized vinyl diene substrate. The compositions, which are novel, are particularly useful as impact modifiers for polyvinyl chlorides.
