Abstract: A new and distinct variety of Euyphorbia plant of the milii group has a very compacy habit with short internodes and very frequent branching that is productive of clavate branches which at the nodes bear persistent long acicular stipular spines. The leaves are oblanceolate to obovate and the plant develops pseudobracts as opposite to subopposite pairs on leafy stems and branches and which subtend a developing leafy branch and/or cyathial branch. The blades of the pseudobracts are usually variegated and have a basic field which in color is usually dominated by a red, purplish red and/or purplish pink hue. The basic field usually has streaks and/or blotches which vary in pattern and size and which in color are usually dominated by a yellow green hue. The inflorescence rarely exceeds three tiers of cyathia and the bract blades of the cyathia are in color dominated by a red and/or purplish red hue.

Abstract: The invention relates to a throttling-pintle nozzle for fuel injection in an internal-combustion engine, with a nozzle needle which lifts off from its needle seat under the pressure of the injected fuel counter to the direction of flow of the fuel.

Abstract: Mops and process for making closed or uncut end mops particularly using single ply cotton yarn having a high degree of twist. The yarn is processed through a fringe making machine into lengths of pre-sewn fringe and the high twist yarn tends to bunch together in thick, ropy masses of yarn strands. The fringe is affixed to mop backs to form a mop, and the mops are then soaked in a high temperature water bath until the ropy yarn strands relax, straighten and separate. The mops are rinsed and transferred to a high temperature hot air dryer and dried until the separate yarn strands twist about their looped ends to form separate, individual doubled ply yarn strands with uncut ends.

Abstract: According to the preferred form of the invention, a pair of thin wheels is rotatably mounted in the bottom of the body of a caster or other load supporting wheeled device in a bilaterally symmetrical array. Each of the wheels has a downwardly facing outer terrain-engaging surface in the general form of a frustocone, and an upwardly facing inner annular bearing surface which is opposed by a complementary annular bearing surface on the bottom of the body. Preferably one or more antifriction washers are interposed between the wheel and body bearing surfaces. This arrangement provides large bearing surface areas which are located directly above the lowermost apex of the frustoconical terrain-engaging surface so that direct vertical loading is applied through the bearing surfaces to the terrain-engaging footprint of each wheel, thereby avoiding cantilever action, avoiding any need for rollable bearings, and permitting the wheels to be very thin and of extremely low profile.

Provided in the areas of the channel junctions are additional support elements, in the ceiling channels, for trolley support. To enable a material- and weight-saving design, the support elements are inserted in the ceiling channels, on support arms, at a specified spacing above the trolley, while above the trolley there is a support plate mounted which is supportable from underneath by the support elements.

Abstract: A sanitary process for efficiently extracting crab meat substantially automatically is disclosed. Live crabs are cooked and debacked in a conventional manner. The debacked crab bodies are then prepared for centrifugally extraction of the meat by advancing the individual bodies serially along a processing line by a conveying means. The processing line trims the claws and legs from the crab and then removes the gills and other inedible materials by brushing in a water jet. The clean crab body is then longitudinally sliced into two half sections in a manner that removes the center partition of the crab body and exposes the meat conveying cavities. The individual half sections are then placed in a centrifugal machine which restrains the complete half shell by an openwork barrier as the meat is separated from the shell by centrifugal forces. The separated meat passes through the openwork barrier and is collected by individual meat receptacles located radially outward from the openwork barrier.

Abstract: A fastening device for connecting a rope to an object includes a shank which contains an aperture through which the rope loops, and in addition a hook at one end of the shank. The hook carries a keeper which pivots on it between closed and open positions, and is urged to its closed position by a coil-type compression spring which encircles the shank. The spring creates rope channels along the sides of the shank, and these channels confine the rope so as to maintain the loop at the aperture. However, the spring may be compressed to expose the aperture so that the rope may be maneuvered through it.

Abstract: A slide fastener 10 includes an end stop which is made of a thermoplastic material and allowed on melting by ultrasonic or high-frequency fusion to permeate yarns of fastener tapes, penetrate the interstices or openings in the tapes and fuse together at the confronting ends of the end stop with the tape sandwiched therebetween thereby firmly anchoring the same in place against movement even under increased stresses.

Abstract: A fastener and method of attachment of such fastener to sheet material to provide attachment of a tubular fastener to the sheet material by extruding, without severing, portions of the sheet material completely through openings on the base portion of the fastener. In one embodiment of the invention, the extruded material is clinched on the top surface of the base portion by clinch members integrally formed with the base portion. The fastener is internally threaded, lightweight and preferably heat-treated prior to attachment to the sheet material to provide fastener strength equivalent to or greater than that of much heavier nuts. Two types of such fasteners may be attached by a method which opens up a hole in the sheet material of a larger diameter than the major diameter of the threads in the fasteners while simultaneously clinching the fastener in place. This eliminates the need to use thread-cutting bolts.

Abstract: A scarfing apparatus for removing a weld bead from a tube being produced by a continuous method wherein the tube enters one end of a rotatable hollow spindle which supports a tool bit. The tool bit has an arcuate shape having a segment which extends 180.degree. or less about the periphery of the tube. The spindle oscillates rotationally causing the tool bit to rock back and forth across the surface of the moving tube to remove the weld bead. The tool bit is formed of carbide steel containing tantalum, titanium and cobalt. The tool bit has a forward face portion and a bottom face portion which define a tooling edge at their intersection. The bottom face portion slopes upwardly at an angle of approximately 3.degree. to reduce friction on the tube. For use with carbon steel tubing, a bit is used having a forward face portion angled approximately 15.degree. from the vertical. For use with stainless steel or aluminized material, a bit is used having a forward face portion angled back approximately 21.degree.

Abstract: A method is disclosed of manufacturing a piston having a skirt on which are formed a plurality of bearing surfaces, each bearing surface being at a predetermined axial position on the skirt, being spaced outwardly of the skirt to a required radial dimension and extending around the skirt with a required circumferential dimension. The method comprises forming the bearing surfaces in at least two stages. First a plurality of projections are formed on a skirt of the piston with each projection being at an axial position in which a bearing surface or surfaces are to be located. The radial and/or axial dimension of the projection exceeds the required corresponding dimension or dimensions of the bearing surfaces. A second step then forms bearing surfaces of the required dimensions. A second form of piston is formed with cylindrical portions which are alternately offset to one side or other of the piston axis to form, one each side of the piston, alternate projecting bearing surfaces and recessed skirt portions.
