Abstract: Cars of a multi-car train are loaded while in transit utilizing an overhead loading hopper into which a load out conveyor delivers bulk material such as coal in quantums to fully and evenly fill the individual receiving cars as each passes beneath the hopper and each quantum of material delivered to the hopper is specially measured to equal the predetermined gross loaded weight of the car in loading position less the car's actual weight as it was measured in transit. Loading of each car from the hopper is regulated by the speed of the conveyor and by an operator controlled diverter gate which initially directs the coal through an aft chute of the hopper which each car reaches first and then through a fore chute to complete its loading.

Abstract: An air compressor has a low torque motor driven piston of the rocking rod type which operates in a cylinder with a closed head containing a discharge check valved port to a compressed air receiving chamber. The piston contains an intake port provided with a thin flexible metal spring closure strip which is inclined at a small angle to the valve seat about said intake port to open on the downstroke of the piston, close on the upstroke thereof and remain open when at rest to facilitate start and restart of the air compressor.

Abstract: A whole fruit size grader comprising a horizontally oscillating table having a generally horizontal flat area on which fruit to be sized is loaded and a sorting area which slopes therefrom downwardly to a prime size fruit collecting area or station. Said sloped sorting area embodies closely spaced side-by-side troughs extending in the direction of the table oscillation. These troughs communicate at their upper ends with the loading area to receive the fruit in response to table oscillation, have oppositely sloped side walls for guiding the fruit to the lower discharge end thereof, and have tapered discharge openings upstream of their lower discharge ends for separating the undersize fruit from the prime size fruit and have associate means in the form of horizontal fins over said discharge openings which retard the fruit as it moves over said discharge openings to influence the separate collection of the undersize fruit.

Abstract: Means is provided in a blast joint, for an oil well, whereby the elements of the blast joint are designed and organized to overcome adverse external conditions encountered in the installation of the joint, as well as those encountered in the operation of the joint in the well, to maintain the structure and operability of the blast joint in a condition favorable to its effectiveness in protecting the production tubing from erosion at its production location in the well.

Abstract: The utility hoses of a welding gun are connected to the inner body of an insulative-sleeve enclosed utility station through which a consumable electrode feeds to the gun. The inner body establishes communication of the gun hoses with sources for said utilities and utilizes couplers which quickly connect and disconnect both the gun hoses from the station and the station from the supply sources for the utilities required by the gun.

Abstract: A method of shaving hair from the human body with a razor wherein the skin area after washing is wet with water and the edge of the razor is wet with a water repellant organopolysiloxane fluid such as dimethyl polysiloxane.

Abstract: A welding gun has a separable nozzle embodying longitudinally curved inner and outer concentric sleeves, and fore and aft-mounted bodies to which the opposed ends of the concentric sleeves are brazed to define an annular gas manifold between the sleeves into which gas feeds through the aft-mounted body. The aft-mounted body detachably seats within a tubular handle and it contains a bore through which the consumable wire electrode feeds to the central bore of the inner sleeve. The fore-mounted body provides for connection of an adapter by which a current pickup tube is fixed to the curved nozzle in line with its inner sleeve to receive the wire electrode. Said fore-mounted body is ported at spaced intervals for discharge of gas from the manifold through the adapter and about the current pickup tube when assembled thereto.

Abstract: The invention provides a blast joint which comprises basically an extended series of short cylindrical rings preferably rectangular in longitudinal axial section, composed of an abrasion resistant material such as cemented tungsten carbide, and disposed coaxially in contact with each other between end retaining rings mounted upon a supporting steel tube which comprises a single section or joined sections of a production tube.

Abstract: This invention relates to an instant silvering solution that does not require the use of applied electrical current for plating the surfaces of copper and copper-based metal electrical connections and contacts. It is particularly designed for the application to these copper and copper-based metal surfaces for the purposes of reducing electrical resistance and the resulting heating created, caused by the build-up of copper oxide on these surfaces.

Abstract: A disc harrow has a shock absorbing and frame attitude maintaining mechanism which embodies a bell crank lever pivotally connected at its apex to the hinged hitch structure of the implement frame. One arm of the lever is operatively connected through a rigid link to the rockshaft which is axially rotated to raise and lower the transport wheels of the implement. The other arm of the lever is connected to one member of a vertically extending spring-loaded link having a second member anchored to the implement frame. This second member has a pair of stops between which a spring is confined in compression; and the first member acts on the spring against one or the other of said stops in response to both raising and lowering of the transport wheels to maintain a constant frame attitude.

Abstract: The outer edge of teeth of tire buffing machine blades is interrupted by oppositely curved arcuate slots which are cupped on centers disposed below the center on which the adjacent one of the leading and trailing deeper cutting side edges of the tooth are cupped. Between said arcuate slots, the outer edge has a shallower arcuate notch the ends of which are obtuse to the tooth outer edge. The portions of the tooth outer edge between the arcuate slots and the tooth cutting side edges are displaced laterally to opposite sides of the teeth and the inner portions of the tooth outer edge between said arcuate slots and the notch are transversely offset to the remainder of the tooth such that the teeth successively present to the tire surface being buffed a first sharply acute deeply cutting edge, then a sharply acute lighter cutting edge of shallower depth followed by an obtuse buffing edge and a more bluntly obtuse second buffing edge which act to finish the tire surface to a required texture.
