Title: Package dispenser for plurality of garments
Inventor: WOOD FREDERICK
IPC: B65D85/07
Filed: 1995-09-18
Abstract: A package dispenser for garments is provided with a body part shape, which holds the garments in an expandable shape. The garments are nested and are placed within each other, and the garments expand and conform to a proper expanded position for insertion of the body part therein into the innermost exposed garment of the plurality of nested garments. In one embodiment, when a vacuum is applied, the garments expand into an open position and the package sequentially dispenses the garments. The garments may be latex surgical gloves or condoms. In another embodiment, when the dispenser is in the form of a flattened container, when the flattened container is squeezed at an open end, the garments are maintained in an open, expanded state, wherein the user inserts the body part into the innermost garment of the plurality of garments. There may be a sealed leak-proof layer in between each garment. This provides extra cleanliness for the inside of the innermost garment that would otherwise be exposed to the outside air.

Patent CA-2160436-A1 (CA)
Inventor: NOEL THIERRY
IPC: E21B17/08
Filed: 1995-10-12
Abstract: Threaded coupling for metal tubes comprising a sleeve (10) with two female threaded sockets (8,9) into which the threaded male elements (2,3) of two metal tubes are screwed. These male elements each have an unthreaded end zone terminating at an end wall (11,12). The two end walls press on each other in the screwed position, forming a metal-to-metal contact. The peripheral unthreaded area next to the end wall has a convex conical surface (14,15) which makes contact with a concave conical surface (19,20) in the sleeve, with positive interference to create a watertight metal-to-metal contact. Shoulder stops allow the male elements to be positioned precisely within a well defined zone of tolerance relative to the centre of the sleeve. Method of forming the coupling is also claimed by screwing a first male element into the female until the coupling engages and its advance is blocked by the two shoulder stops making contact, then screwing in the second male element until the two end walls meet.

Filed: 1996-04-23
Abstract: Liposome-encapsulated quinolones and specifically liposome-encapsulated ciprofloxacin dramatically enhances macrophage functions, induces NO production and augments the production of cytokines, rendering the composition an immunoprophylactic and immunotherapeutic agent with unique clinical potential.  Liposome-encapsulated ciprofloxacin and other quinolones could be extremely useful in antimicrobial, anticancer and AIDS therapies.  In such cases, the immunological status of the patient is often compromised or suppressed, making them susceptible to microbial infections and to the development of tumor growth.  Selective augmentation of cellular immunity by activation of the microbicidal and tumoricidal activities of macrophages, induction of NO and cytokine production could be of primary importance to such patients in terms of protecting them against microbial infections and inducing their cellular host defence to tumor cells.

Title: Twist-on wire connector with torque limiting mechanism
Inventor: KORINEK CHRIS W
IPC: H01R4/22
Filed: 1996-10-11
Abstract: Ends of several electrical wires are joined by a connector to a predefined torque level. The connector includes a hollow body having a open end, a smaller closed end and an outer surface extending between the two ends. The outer surface has a portion with an equilateral polygonal cross-section for engagement by a tool to effect rotation of the body. The portion of the body is specifically designed with elements, such as the corners of the polygon, which become rounded when the tool applies torque that exceeds the predefined torque level. Such deformation of the body thereby prevents excessive torque from damaging the electrical wires. Another portion of the body is provided to enable another tool the engage the connector for removal from the wires.

Title: Three-dimensional braided covered stent
Inventor: THOMPSON PAUL J
IPC: A61F2/06
Filed: 1997-04-15
Abstract: A prothesis (18, 108, 120) for transluminal implantation consists of a flexible tubular three-dimensionally braided structure of metal or polymeric monofilaments (32, 110, 126), and polymeric multifilament yarns (42). The prosthesis can be elastically deformed to reduce its diameter through axial elongation. The monofilaments and multifilament yarns are arranged in axially spaced apart helices, concentric on a common central axis of the prosthesis. The monofilaments are selectively shaped before their interbraiding with the multifilament yarns, either by an age-hardening or other heat-setting stage, or a cold-working stage that controllably plastically deforms the strands. The shaped structural strands cooperate to impart to the prosthesis its nominal shape and resilience. The textile strands cooperate to provide one or more layers of sheeting (40) that reduce permeability and thereby enhance the utility of the prosthesis as a vascular graft. An alternative embodiment prosthesis (132) includes elastically and plastically deformable structural strands (140), selectively plastically deformed by cold working, then three-dimensionally braided to form the prosthesis.
