Title: Safety sheath for needles, sharp instruments and tools
Inventor: ORGAIN PETER A
IPC: A61M5/32
Filed: 1991-05-16
Abstract: A reusable arrangement to protect against accidental contact with the surfaces of needles and other invasive medical instruments.  In one embodiment, the invention comprises a collar that engages a sharp surgical instrument in advance of its sharp end. Attached to the collar by means of a flexible hinge is a slotted longitudinal member (21), which swings over the sharp end of the instrument, thereby engaging either the collar or the portion of the instrument just in front of the collar and also retaining the instrument behind a keeper shelf (44). In second and third embodiments, the collar extends into an arcuate sheath, which is molded to assume a rest position that bends away from the sharp end of the instrument. This arcuate sheath ultimately forms an elbow curl (52) and extends back toward the collar, thereby forming upper and lower arcuate portions. The lower portion terminates in a set of flanges (56) that help define a trough (54) to carry the sharp end of the instrument. In a fourth embodiment, the keeper shelf (44) is modified so that it may be engaged with the opposite side of the longitudinal member (21) to lock this member over the sharp instrument. The longitudinal member may also be equipped with wing member (92) to facilitate movement of the sharp instrument around the keeper shell (44). In a fifth embodiment, the locking mechanism comprises a set of flanges (97) depending from the longitudinal member (21) that are gripped by complementary catches (98) on the collar when the device is placed into the closed position.

Title: Tool for pulling clutch from washing-machine motor
Inventor: RUBINO MICHAEL
IPC: H02K15/00
Filed: 1993-03-01
Abstract: ABSTRACT OF THE DISCLOSURE    A tool for pulling off the clutch mechanism of one specif-ic maks of waching machine. The tool has  main mounting plate from each end off which passes therethrough an elongated screw. The mounting plate has an enlarged central hole for passing therethrough a large tubular member which is threaded on its outer circumferential surface, and which is hollow in it in-terior. The tubular member receives in its hollow interior the tubular sleeve of the clutch mechanism when the tool of the invention is used for pulling the clutch mechanism off from the drive shaft. At the bottom of tubular member, there is provided a larger-diameter head, having a pivotal latch. After placing the tubular member over the tubular sleeve, the pivotal latch is closed over cutout portion at the lower portion of the tubular sleeve, whereby the latch is thus in locked engagement with the tubular sleeve but free of contact with the inner drive shaft. The tool is then used by rotating a nut mounted on the upper end of the tubular member and above the mounting plate. Since the bottom heads of the two screws at the ends of the mounting plate are in contact against the motor housing, rotation of the nut causes the tubular member to be lifted up thereby,  bringing along with the enlarged bottom head and tubular sleeve,  and,  therefore,  the entire clutch mechanism along with it.

Title: Apparatus for dispensing flowable materials from a pouch
Inventor: WIRSIG RALPH C
IPC: B65D83/00
Filed: 1991-11-13
Abstract: An improved piston for a pouch dispenser is disclosed. The dispenser is adapt-ed to contain a pouch (52) of flowable material, and has lid (35) to keep the pouch within the dispenser and a piston which is adapted to move toward the lid and press against a first end (113) of the pouch, and push the flowable material out of the pouch through a hole in the second end of the pouch. The piston (47) has a peripheral lip (115) extending towards the second end of the pouch. The peripheral lip extends for a length sufficient to cause the film from which the pouch is made to pleat (116) in a di-rection transverse to the longitudinal axis of the dispenser when the material in the pouch is squeezed from the pouch by the pressing action of the piston. The lid (35) and piston (47) are adapted to allow the peripheral lip to nest with the lid and to prevent the pleats from hindering essentially all of the material from being squeezed out of the pouch.

The bottom end of the load cell is attached to the support frame so that the support frame is suspended by the load cells when the lifting mechanisms are extended. The lifting mechanisms and linkage assemblies of the weighing cells are attached to the truck or trailer frame.    A lock down mechanism integral to the load cells secures the load support frame when the lifting mechanism is in a rest position.
