Title: Machine for the automated packaging of needles and attached sutures and method of utilizing the packaging machine
Inventor: DEMAREST DAVID
IPC: A61B17/06
Filed: 1995-01-11
Abstract: An automated machine for the high-speed packaging of multiple surgical needles each with an attached suture into a tray and detachable cover structure providing a suture package utilized for the packaging of the needles and attached sutures. Additionally, the automated packaging machine incorporates operative mechanism adapted to wind the sutures into a peripheral channel of the tray and facilitating the attachment of the cover to the tray which contains the needles and attached wound sutures, and from which cover there is concurrently formed a separate product-identifying label as a component of the tray upon removal of the cover to gain access to the contents of the tray.  The automated packaging machine also provides for a rotary turret or turntable for the high-speed sequential loading of successive forwardly indexed trays with the needles and attached sutures; the indexed advance of the needle and suture-filled tray to a suitable suture-winding station of the machine, the subsequent conveyance of the trays containing the needles and attached wound sutures to a cover-applying station of the machine to provide the suture packages, and the subsequent automated removal of the completed suture packages from the machine.  Furthermore, the present invention is also directed to the provision of a novel method for the automated packaging of multiple surgical needles and attached sutures into trays and the application of covers thereto in sequential production steps through the intermediary of the automated packaging machine facilitating the high-speed output of suture packages containing multiple needles and attached sutures.
Patent CA-2140518-A1 (CA)
Inventor: POLLART KENNETH A
IPC: A23L5/10
Filed: 1994-05-10
Abstract: A self limiting dispersion of a conductive material in a binder is disclosed wherein the conductive material consists essentially of a carbon material having a structure selected to undergo percolation when dispersed in the binder at a concentration of from about 10 weight percent to about 45 weight percent. The binder comprises a thermoplastic material selected to go through a first order phase transition or a second order transition at a temperature from about 200 °F to about 480 °F and the dispersion is formulated near the conductance percolation threshold so that its electrical conductivity drops precipitously ((e.g., at least about 1.5 to about 2 orders of magnitude) above the binder transition temperature. The dispersion of the conductive material in the binder is especially suitable for use as a self-limiting microwave heater material which is either a molding composition, surface coating composition, and especially a composition that can be applied to a substrate by printing.

Title: Crosslinked cellulose products and method for their preparation
Inventor: GRAEF PETER A
IPC: D21H11/20
Filed: 1993-06-25
Abstract: The invention is a method of making a wet formed, sheeted, readily reslurriable sheeted crosslinked cellulose and the products made by the method. Crosslinked wood pulp fibers tend to be quite brittle. If crosslinked while in sheeted form, the sheets cannot be readily defibred, either in a wet or dry state, without serious fiber degradation. The sheet products of the present invention can be easily redispersed or repulped in water without significant fiber breakage. The present products are made by including within the sheet, while still in wet form, a debonding or softening agent which is preferably added before the latent crosslinking reactant. Most preferably the debonder is added prior to the headbox of a paper machine and the crosslinking reactant is applied near theend of the forming wire or at the press section. The treated sheet is dried conventionally. Crosslinking may occur entirely during drying or during a period of additional heating, usually at a temperature in excess of 100 °C for a short period of time.  Conventional debonding agents and crosslinking reactants are suitable. The softening agent apparently reduces or prevents adhesive bonding between adjacent fibers caused by polymer formation external to the fibers under reaction conditions.

Abstract: A method for controlling spread in cookies uses in the cookie dough a shortening comprising geometry-altering triglycerides bearing long C16 to C22 saturated fatty acid residues and short C2 to C4 acid residues. In a preferred embodiment, the triglycerides have a solid fat index of about 10 % to about 70 % between 15°C and 30°C, and the long residues are a mixture containing at least about 75% stearic acid residues while the short residues are derived from a mixture of acetic and propionic acid, a mixture of acetic and butyric, or a mixture of acetic, propionic and butyric acid. The method is especially adapted to reducing spread in cookies containing an ingredient that promotes spread such as polydextrose. Cookies prepared with polydextrose and geometry-altering triglyceride compositions are low in calories.
