Abstract: A cover for a luggage case, embodying decorative side panels of simulated multi-laminar construction. Portions of the periphery of the principal sheet of covering material are cut away and decorative strips fastened in overlying outwardly projecting relation to the cut away portions to complete the outer contour of the principal sheet. The edge of a surrounding strip is attached, as by stitching, to the outer peripheral edge of the combined principal sheet and decorative strips. After securing the overlapping ends by stitching together, the surrounding strip is readily disposed at a right angle for attachment to the shell of the luggage case.

Abstract: A reagent and a method for using the reagent for treating a solid material disposed in a liquid medium and having an oxygen-controlled surface condition. The reagent includes a liquid hydrocarbon, a reducing material and an activator material. The liquid hydrocarbon has a specific gravity different from the specific gravity of the liquid medium. The reducing material is present in an amount sufficient to establish a reducing environment around the solid material for breaking the oxygen control on the surface of the solid material. The activator material is present in an amount sufficient to establish an electrostatic charge on the solid material after the oxygen-controlled surface condition has been broken. A more specific feature of the invention is directed to the method of flotation of extremely fine bituminous coal having an oxygen-controlled surface condition. The reagent is useful in froth flotation processes and in bath flotation and separation processes.

Abstract: A golf putter with an adjustable sighting device to improve accuracy of putting, particularly on hilly terrain. A directional dial is fixed above the club head with a pointer just below the dial being rotatable by the golfer to different positions relative to the dial to fix a direct line between the ball and the cup independently of the angular position of the club head. The pointer is carried in a horizontal position generally at right angles to a rod that rotates in a bore within a tubular fitting by which the club shaft is secured to the club head. A steel cable coaxially secured to the rod extends telescopically through the hollow club shaft to a rotary cap or knob on the upper end of the club shaft by rotation of which the golfer is able to adjust the pointer relative to the dial to obtain a directional fix on the cup.

Abstract: A collar holder is provided for securely holding collar tabs and providing a decorative and ornamental effect in the form of an elongated face plate having a front and back surface, a pair of resilient jaws fixed at one end to said face plate on the back surface intermediate its length the other end of said jaws being freely movable toward and away from the back surface of said face plate adjacent its end, a plurality of interdigiting teeth on each of said jaws and the back surface of said face plate adjacent their ends, an open generally curved receptacle opening in said jaws and back surface adjacent said teeth and between said teeth and said one end of the jaws fixed to the face plate and decorative means on the top surface of said face plate.

Abstract: A derail guard to prevent derailment of railed vehicles which can be readily attached to existing equipment is disclosed. The derail guard is particularly useful for track construction and repair equipment.

Abstract: An inertial switch device, for installation in an electrical circuit of an automotive vehicle, to signal excessive rates of acceleration, deceleration and turning for the purpose of preventing abusive driving which wastes gasoline. The switch device comprises a housing having a closed chamber with a concave bottom surface containing a globule or drop of mercury and a plurality of circular contacts supported therein so that the drop of mercury successively contacts them when a momentum force causes the drop of mercury to climb a side of the dish. The circular contacts are of increasingly larger diameter as the drop climbs the side of the dish with increasing inertia and are arranged in circuit-closing relation to a warning signal device, either audible or visible.

Abstract: A conduit end is sealed around one or more than one insulated conductor by using a chamber (4) having a peripheral wall, a base with an opening through it communicating with the conduit (2) and an opening opposite the base. The conductor(s) (3) extend through both openings; a pre-formed annular body of a setting resin composition (8) is inserted while in a pasty or viscous condition into the chamber to encircle the conductor or conductors. Axial pressure is then applied to the still pasty or viscous annular body to cause it to flow and form a sealing body in peripherally continuous contact with the chamber and with the, or each, insulated conductor, after which the resin composition sets. A kit for use in the method is also claimed.

Abstract: A method and apparatus are provided for heating and/or drying particulate materials such as coal wherein the particulates are fed into a direct heating fluidizing chamber, carried in a stream of heated oxygen-free gas at a temperature sufficiently high to heat the particles to a preselected temperature. The particles are then removed from the gas stream at the preselected temperature and then the gas is reheated in a heat exchanger and recycled. Where the particulate material to be dried yields a vapor, such as steam, the vapor is used as the transport or fluidizing gas. Means are provided for removing and/or condensing such vapor beyond the amount needed for fluidization.

Abstract: A method for producing kaolin pigments of improved coated brightness and opacity is provided in which kaolin is degritted, heated to the level of substantially minimum brightness and then leached. The kaolin may be comminuted before treatment, after heating or after leaching to control particle size distribution.

Abstract: A dome structure having a stabilizer pole forming the apex of the dome. A plurality of spaced riser beams are arched and terminate at the apex and join a plurality of arched panel members. Each of the panel members taper from a wide base to a narrow top at the apex. Each panel member is formed with an interfitting edge flange which attaches to a riser beam through a resilient connection.

Abstract: The mill comprises essentially a roughing train having a reversing roughing stand or stands and a finishing train having a reversing finishing stand or in-line finishing stands, the roughing and finishing trains being disposed with pass lines parallel to each other and at different elevations, the work in the roughing train progressing in the opposite direction from the work in the finishing train. The roughing train for strip and light plate is provided with a hot upcoiler at each end positioned above the table so that slabs and breakdowns pass beneath them, but adapted to coil and payout strip of coiling gauge. The delivery end of the roughing train is laterally opposite the entry end of the finishing train and separate mechanisms are provided for transferring coils and plate broadside from roughing train to finishing train.
