Abstract: The present invention relates to a covered yarn for constituting at least a portion of a remedial-support article. In accordance with the invention, the covered yarn is formed of an elastic central core of translucent material, and of at least one covering yarn, likewise of translucent material, and wrapped around the central core. The invention also provides a remedial-support article in which at least the essential portion is constituted by the above-specified covered yarn. In particular, when the remedial-support article comprises a knitted face yarn and a weft yarn, it is advantageous for the weft yarn to be constituted by the above-specified covered yarn, the face yarn itself being constituted either by a traditional yarn, or else likewise by the above-specified covered yarn.

Abstract: An anvil for a wood chipper includes an anvil body having a top surface, a bottom surface, and longitudinally extending side surfaces between the top and bottom surfaces. At least one of the side surfaces is adapted to accept an insert shaped and dimensioned to fit into the adapted side surface of the body. Means within the body for firmly holding the insert in contact with the adapted side surface are also provided. The insert presents a leading edge functioning as the anvil's leading edge.

Abstract: The invention relates to a remedial support appliance for medical use, comprising an elasticated knit main portion for compressing a leg or an arm in order to treat venous or lymphatic insufficiency. According to the invention, the main portion is extended upwards by an elasticated garter band constituted by an elasticated lace or braid covered on the inside with a pattern made of an antislip material, the fibers constituting the braid or the lace of said band being selected in such a manner that the band presents an elongation characteristic of shallow slope and simultaneously exerts pressure on the limb concerned that is less than the pressure exerted thereon by the main portion of the appliance in the vicinity of said band.

Abstract: A soil retention wall system 10 includes a plurality of vertical piles 12 placed in spaced succession. A plurality of hollow polymeric lagging members 14 are stacked transversely relative to, and spanning between, successive piles to form the wall. Each lagging member is formed from a shell having a major wall 106 defining top and bottom surfaces 28 and 30, and first and second endwalls 36 and 38 each adapted to be engagable with an adjacent pile. In a preferred embodiment, the shell 24 is of unitary, one-piece construction.

Abstract: A multilayer decorative composite, essentially of thermoplastic thermoshrinkable material, for packaging, and a process for applying such composite. The container carries on its outer surface a film of thermoplastic thermoshrinkable material of coefficient of shrinkage substantially identical to that of the plastic material of the body of the container, so that it remains intimately thermally bonded to the walls of the container during shrinkage of these latter at the time of cooling, for example after thermoforming.

Abstract: Corn sterilizing machine of the type using rotary blades. The machine uses a castrating head in the form of a case enclosing a rotary blade. The front surface of the case has a slot allowing for the introduction of the panicle to be cut. Each one of the vertical edges of the slot has a pivotable shutter having two upper and lower ramps, respectively.

Abstract: An ampule for an automatic hypodermic syringe comprises at least two axially aligned and hermetically separated compartments containing respective medicated substances. A nipple member is disposed at one end of the ampule. A needle holder is slidably mounted in said nipple member and supports a hollow needle. An intermediate partition normally hermetically separates the two compartments. The intermediate partition has a valve member adapted to open a path of flow through the intermediate partition to bring the second of the compartments into communication with the needle hollow after a first of the compartments is substantially emptied. Preferably, there are two intermediate partitions and three compartments.

Abstract: A quick-coupling connector for an air valve comprising, in one-piece molded plastic construction, a body for receiving the air valve, an operating member rockably mounted on the body about a pivot axis, a strap which defines a preloaded leaf spring joining the operating member to the body and defining a preloaded leaf spring for urging a clamping member carried by the operating member toward a clamping position.

Abstract: End members for flexible connectors for bicycle pumps are provided, a first end member is fixed to one end of a flexible tube and to be connected to a valve of a tire and the second end member is to be connected to the other end of the flexible tube for connection to a pump. The first end member is made of one piece of molded construction and, at one side of a middle zone has an anchoring stub which carries a cap at its free and by means of at least two frangible bridges. At the other side of the middle zone the first end member has means for linking the connector with the valve of a tire. The middle portion also has resiliently deformable portions for holding the connector in a bore in the handle of the pump. For assembling the first end member with the tube, the cap is fitted over an end portion of the tube and, the bridges are severed and the anchoring stub is engaged inside the flexible tube.

Abstract: A portable pump for inflating tires, particularly bicycle tires. The portable pump comprises a pump body in which there is movably disposed a piston mounted to the end of a rod which is operable in a reciprocating motion. The reciprocating motion is effected by movement of a handle attached to the rod and a spring which is interposed between the pump body and the handle. The piston rod, at its terminal portion remote from the piston, has an extension capable of sliding movement within the handle and which also carries at least one locking structure. The locking structure permits either immobilizing the extension within handle with the spring being neutralized, or sliding movement of the extension in the handle against the force of the spring.

Abstract: An emergency release device for the strap of a toe clip for a bicycle pedal. The release device comprises a release member pivotally mounted on free end of the toe clip. One end of the strap is attached to the release member and the other passes through an aperture in a buckle associated with the release member. In one embodiment the buckle consists of a buckle lever, and a passageway is provided through the release member itself. In another embodiment the release member is releasable attached to the buckle. The release member includes a latching member and in response to the pivoting of the rider's foot in the pedal the force exerted on the strap displaces the latching member to its inoperative position. The release member pivots relative to the toe clip thereby permitting the rocking of the buckle lever in the first embodiment or the release of the buckle through a hooking member in the other embodiment.

Abstract: In apparatus for rejecting from coins or tokens those whose magnetic characteristic exceeds a prescribed threshold, said apparatus comprising a path for the coins having an opening in which a first magnet engages when a magnetic coin passes along the path opposite the opening and, upstream of the first magnet, a second magnet, the improvement that the magnets are carried by an integral mounting and are separate pole pieces and the second magnet is shaped or positioned so that the magnetic force passing in front of it along the path is less than that with which the first magnet is attracted by this same coin when it passes in front of the opening.
