Title: Improved syringe guard system for a unit dose syringe
Inventor: MITCHELL DAVID W
IPC: A61M5/24
Filed: 1999-11-08
Abstract: A guard for a medical cartridge, such as a pre-filled syringe, includes a bo dy having an open proximal end communicating with a cavity for receiving the cartridge, and a shield slidably attached to the body. The body has a semi- rigid cantilever member on its distal end from which a stop tab, having a sloped distal edge and a blunt proximal edge, extends. The shield includes a n elongate opening for receiving the stop tab, thereby allowing the shield to slide between unguarded and guarded positions for exposing and covering a needle, respectively. During assembly of the shield and body, the stop tab slidably engages an assembly tab on the shield, deflecting the cantilever member inward while the stop tab passes under the shield, the sloped distal edge of the stop tab minimizing damage to the stop tab or shield. In the guarded position, the blunt proximal edge of the stop tab engages a proximal  wall of the elongate opening to prevent further distal movement beyond the guarded position. The body and shield include cooperating detents and distal  detent pockets having oblique proximal corners that mutually engage to preve nt proximal movement from the guarded position. Proximal detent pockets are als o provided that include sloped distal edges terminating in blunt distal corner s. The detents include sloped distal edges terminating in blunt distal corners that engage the distal corners of the proximal detent pockets to create an initial resistance to distal movement from the unguarded position.

Title: Authenticating method between a smart card and a terminal
Inventor: COOREMAN PASCAL
IPC: G06F21/44
Filed: 1999-11-04
Abstract: The invention concerns a method enabling a smart card and a terminal whereto it is connected to authenticate each other. The invention is characterised in that at the end of each transaction the terminal calculates, from data representing the card at said transaction end, a secret code CSC¿2? which is recorded in a zone ZCSC with unprotected access in the card memory and an authentication certificate CA¿2? which is recorded in a zone ZCA with protected access of the memory by presenting a secret code CSC¿2?. At the next transaction, the terminal calculates, by means of data contained in the card, a secret code and an authentication certificate which are compared to those previously recorded to perform authentication. The invention is applicable to smart cards.

Abstract: The invention relates to a method for separating lignocellulose-containing biomass, especially wood, into the essential components in the form of lignin, hemicellulose and cellulose, with the following steps:  a) pre-hydrolyzing the lignocellulose-containing biomass by treating it with water or steam; b) extracting the hydrolyzed hemicellulose obtained by pre-hydrolyzation with an aqueous medium; c) extracting the process-modified lignin that remains in the residue with an alkanolamine, isolating the lignin, recovering the alkanolamine, whereby the alkanolamine is not substituted by alkyl groups at the nitrogen atom, and d) obtaining a cellulose raw material. The inventive method is characterized in that hemicelluloses and lignin can be specifically separated from the cellulose in two different process steps. For this purpose, simple and commercially available system components can be used that facilitate an economical operation also with small installations.

Patent CA-2378960-A1 (CA)
Title: Rotary piston engine
Inventor: DI PIETRO ANGELO
IPC: F01C1/04
Filed: 2000-07-14
Abstract: A non-reciprocating engine comprising a hollow cylindrical shaft driver (13) located in a cylindrical stator cavity (14) of a stator. A number of expansion chambers (43) form between the outer wall of the shaft driver, the stator wall and movable dividers (25) which extend from the stator to bear on the shaft driver. The expansion chambers expand and contract during operation of the engine. An output shaft passes centrally through the stator cavity and shaft driver and has offset bearings (34) which bear on the inside surface of the shaft driver. Inlet ports in a removable inlet end plate of the stator allow pressurised air or air/fuel mixture, for example, to be introduced into the expansion chambers. Sequential expansion and contraction of the chambers around the circumference of the shaft driver causes a combination of orbital and rotational movement of the shaft driver and consequential rotation of the output shaft. The shaft driver rotates at only a fraction of the speed of rotation of the output shaft (in the order of 1/10th - 1/20th the speed of rotation of the output shaft). One orbit of the shaft driver is equivalent to one rotation of the output shaft.

Inventor: DOLLAR CHARLES RANDALL II
IPC: G06F19/00
Filed: 2002-03-27
Abstract: Disclosed is an arc detection circuit for monitoring an electrical distribution system which results in detecting arcing in the electrical distribution system and the ability to provide notification and protection for such arcing. The system functions to monitor the electrical distribution system to sense the frequencies of signals in the system using appropriate filtering. One type of filtering which may be used is based upon a heterodyning circuit which provides variable frequency filtering for filtering a signal representative of the current in at least one electrical circuit of the electrical system. The heterodyning circuit output is configured to produce a signal which may be logarithmically related to the filtered signal. If the output signal exceeds a predetermined limit (representative of noise) for a predetermined period (representative of a typical arc duration), the system generates an arc signal. The arc signal may then be used to operate a circuit interrupter or an indicator in a circuit protection system.

Title: Printing device or printing method
Inventor: SCHULTHEIS BERND
IPC: B41M1/34
Filed: 2000-08-11
Abstract: The invention relates to a printing method using at least one transfer roller, whose roller surface is charged with a coating material, for example a toner.  Said coating material is directly or indirectly transferred from the transfer roller to a support surface of a transfer element, before being transferred at least partially from the transfer element to a workpiece to be coated.  According to the invention, the transfer element has a stretching element which forms the support surface and said support surface is stretched in the direction of the surface by means of a stretching device. This ensures that a method of this type can also be used as a simple means of coating 3-dimensional surfaces which are curved in space.

Title: Long-life traveling spark ignitor and associated firing circuitry
Inventor: SUCKEWER ARTUR P
IPC: H01T13/50
Filed: 2000-06-16
Abstract: An ignitor and associated electronics for igniting a combustible mixture in a cylinder of an internal combustion engine are described. The ignitor includes at least two spaced-apart electrodes that define a discharge gap. The space between the electrodes is substantially filled with a dielectric material. The dielectric material is spaced-apart from at least one of the electrodes to provide an air gap over which an initial voltage breakdown between the electrodes will occur. The air gap serves to vary the location of the initial breakdown and as a barrier to a short circuit between the electrodes due to carbon and/or metal deposit buildup on the dielectric material.     The associated electronics provide a first potential between the electrodes that generates a plasma between the electrodes. Then the volume of the plasma is increased by the application of a second potential that creates a current through the plasma. The plasma, as well as the current passing through, is swept outward due to the interaction of Lorentz and thermal expansion forces with the plasma. Also described are relative orientations of the electrodes that lead to greater plasma formation.
