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.
