  • Patent number: 6607507
    Abstract: A single-use syringe has a barrel which can constitute a one-piece extrusion, and a shank which is reciprocably guided in the barrel and the distal end of which carries a plunger movable in the barrel toward and away from the needle-carrying front end portion of the barrel. The coupling between the plunger and the shank includes a set of circumferentially spaced-apart breakable spokes which can be of one piece with the distal end of the shank as well as with the plunger. The spokes break not later than when the shank completes a forward stroke during which the plunger expels a flowable substance, such as a medicine, from a chamber located in the barrel between the needle-carrying front end portion and the plunger. The plunger, the spokes and the shank can constitute a one-piece extrusion.

  • Patent number: 6572306
    Abstract: One or more electric and/or data transmitting cables are confined in an elongated strip-shaped body containing a hardenable resin or the like, and the body is placed against a portion of the internal surface of an underground sewage, water or other pipe. An expandible tubular liner is thereupon introduced into the pipe and is expanded to press the body against the pipe. The body is caused to set, by conveying a hot fluid through the liner and/or by electrically heating the cable or cables, and to adhere to the internal surface of the pipe. The liner can remain in the pipe and can be bonded to the strip-shaped body and/or to the remaining portion of the internal surface of the pipe. Alternatively, the liner is caused to collapse and is withdrawn from the pipe once the strip-shaped body is bonded to the internal surface of the pipe.

  • Patent number: 6321510
    Abstract: Sipping straws are confined in discrete envelopes while advancing in a single file of spaced-apart straws through a wrapping station. The envelopes are obtained from a continuous strip of wrapping paper which is conveyed to the wrapping station in the direction of advancement of the file of spaced-apart straws and is draped around the straws in such a way that one of its longitudinally extending marginal portions overlies and adheres to the other marginal portion with simultaneous formation of a seam rather than an outwardly extending fin. The thus obtained tubular wrapper is thereupon severed in the gaps between successive spaced-apart straws, and the end portions of the thus obtained discrete envelopes are sealed by knurling, e.g., simultaneously with severing of the tubular wrapper.

  • Patent number: 5593405
    Abstract: An endoscope has an elongated flexible guide the distal end of which can be introduced into a selected chamber of a human or other animal heart or into the internal space of another body organ. The tube confines a major portion of an elongated flexible sheath the distal end of which carries an inflatable balloon for the distal end portions of elongated flexible optical conductors some of which serve to illuminate selected portions of a surface bounding an internal space. The remaining conductors serve to transmit images of the illuminated portions of the surface toward the proximal end of the tube. When inflated, the ballon shields the distal ends of the conductors from contact with the body fluid in the internal space. A three-dimensional frame is provided to maintain the inflated balloon in any one of a number of different positions in a body cavity.

  • Patent number: 5279696
    Abstract: Uniting bands in the form of heat-sealable labels which bear encoded information are applied to exposed photographic films to join the films end-to-end. The encoded information is decoded by a reader before the labels are applied to the films to thus ensure that the hot sealing member which is used to apply labels cannot destroy or distort encoded information prior to decoding. Decoded information is used for the application of corresponding information to envelopes for exposed and developed films and for the prints of images of the respective film frames.

  • Patent number: 5271452
    Abstract: A continuous casting apparatus has a continuous casting mold which defines a casting passage. The walls of the mold are provided with conduits which are connected with a source of pressurized gas and open into the casting passage at locations downstream of that where the meniscus is normally established. During withdrawal of a continuously cast strand from the mold, gas is injected into the casting passage at a pressure sufficient to force the meniscus away from the walls of the mold. This eliminates the friction which normally exists between the mold and the meniscus so that the mold need not be oscillated during strand withdrawal. The continuous casting apparatus accordingly does not require an oscillating mechanism for the mold.

  • Patent number: 5267576
    Abstract: A cigarette rod making machine wherein the flow of loosely intermingled tobacco shreds, tobacco ribs and foreign objects (such as nuts, bolts, pieces of wire and/or particles of plastic material) is classified to segregate the ribs and foreign objects from the shreds. The ribs are thereupon separated from foreign objects in a sifter and are comminuted in a rotary cutter prior to being readmitted into the flow downstream of the classifying location(s). Successive increments of the flow are converted into successive increments of a stream which carries a surplus of shreds and is trimmed for conversion into a filler which is ready to be wrapped into cigarette paper. The comminuted ribs are admitted into the flow at a location such that they are confined in the central portion of the filler.

  • Patent number: 5263348
    Abstract: A cylinder lock for use in motor vehicles and elsewhere has a case for a rotatable and axially movable sleeve-like guide which receives a rotatable cylinder having a keyhole and being locked to the guide by tumblers when the key is withdrawn. A detent is installed between the case and the guide to normally prevent rotation of the guide except when the guide is acted upon by a large force which causes it to deactivate the detent as a result of certain axial movement of the guide and cylinder in the case. A clutch between the cylinder and a motion transmitting element for a bolt of the lock is engaged as long as the detent is operative but is disengaged not later than when the detent permits the guide to turn in the case.
