Inventor: DIAMOND RICHARD B
IPC: A61M5/178
Filed: 1998-10-27
Abstract: Method and apparatus for holding and selectively positioning medical needle and syringe assemblies.  The device comprises the combination of a housing and a retainer insert interconnectible therewith.  The retainer insert is provided with a plurality of retainer holes formed thereon for receiving and frictionally retaining a needle cap extensible through respective ones thereof. Each respective needle cap retained thereby is oriented such that when the needle portion of a needle/syringe assembly  is  placed  therewithin,   the  assembly  is maintained  in  fixed  position.    Following  use,  the contaminated needles are removed from the device and disposed of via conventional means while the needle caps remain frictionally retained within the retainer insert. In the preferred embodiment, the retainer holes formed on the retainer insert are arranged in a row-like fashion to organize use of multiple needle/syringe devices, and may further be formed to take any of a variety of shapes necessary to provide adequate frictional retention of a given needle cap.

Title: Modular conveyor system having multiple moving elements under independent control
Inventor: FORTUNA JEFFREY JOHN
IPC: B65G54/02
Filed: 1998-05-01
Abstract: The modular conveyor system (20) comprises n interconnected track sections (26), forming a continuous track (24), wherein each track section (26) features a plurality of individually controlled coils (35) stretching along the length thereof. Plural pallets (22), each having thrust producing magnets, travel independently along the track (24). The track (24) also comprises multiple linear encoder readers (50) spaced at fixed positions therealong, and each pallet (22) includes a linear encoder strip (45) having a length R greater than the spacing E between the readers (50). Track section controllers (90) associate the encoder strips (45) with only one reader (50) at any time in order to resolve the position of the pallets based on the fixed position of the readers and the relative positions of the strips in relation thereto. The section controllers (90) also regulate and commutate the coils (35) of the corresponding track sections (26) in order to independently control each pallet (22).  Communication links (92) interface adjacent section controllers (90) and enable them to transfer the pallet position-detecting responsibility between one another when a given pallet straddles adjacent track sections (26). The section controllers (90) also provide coil regulating signals to each other in the event a given moving element spans coils (35) situated in adjacent track sections (24). The electromagnetic structure and distributed control architecture of the conveyor system (20) enable it to independently control multiple practical pallets yet be constructed out of modular track sections, with little practical restriction on the length of the conveyor system or the number of pallets controlled thereby.

Filed: 1999-12-07
Abstract: A shield is provided for the protection of the inner convolutions of a coil of sheet material, the coil having a central opening adapted to be engaged by a lifting device such as a probe inserted into the opening and then raised. The shield has a first section for insertion into an end of the central opening of the coil, the first section being part-cylindrical and shaped to span a substantial part of the periphery of the central opening. The shield further has a second section attached to the first section and extending outward to an outer edge, so that the second section abuts the end of a coil into which the first section has been inserted. At either peripheral end of the first section there is a wing section angled generally outwardly away from the axis of curvature of the first section so that, when the first section is positioned against the top of the central opening of a coil, the wing sections bear against the inside of the central opening and urge the first section upwardly, thus keeping it in place.

Title: Absorbent interlabial device treated with a polysiloxane emollient
Inventor: KLOFTA THOMAS JAMES
IPC: A61F13/82
Filed: 1998-06-03
Abstract: Absorbent devices, and more particularly absorbent devices that are worn interlabially by female wearers for catamenial purposes, incontinence protection, or both, that have an emollient composition on their body-contacting surface are disclosed. The interlabial device has a body-contacting surface that is pre-moistened or pre-treated with an emollient to prevent drying of the wearer's labial tissue and to reduce friction of the structure against the wearer's labial tissue. The absorbent device is preferably capable of maintaining contact with the inside surfaces of the wearer's labia majora when worn. The emollient composition comprises a plastic or fluid emollient such as mineral oil, petrolatum and/or polysiloxane an immobilizing agent such as a fatty alcohol or wax to immobilize the emollient on the body-contacting surface of the device, and optionally a hydrophilic surfactant to improve wettability of the coated surface. Because the emollient is substantially immobilized on the surface of the absorbent device, less emollient is required to impart the desired therapeutic or protective emollient coating benefits.
