Patent CA-2500423-A1 (CA)
Inventor: NORTON JOHN D
IPC: A61N1/39
Filed: 2003-09-26
Abstract: A method and an apparatus for performing maintaining a charge in an electric al energy storing device, such as a capacitor. A set-point voltage for the electrical energy storage device is used during an initial device charging process to charge the storage device to the set-point voltage. A charge maintenance process is also performed that offsets charge loss due to leakag e currents, polarization currents and the like. The charge maintenance process involves providing a charge maintenance current to the storage device until the storage device is therapeutically discharged (e.g., during cardiac defibrillation therapy delivery).

Patent CA-2502891-A1 (CA)
Inventor: GELLMAN BARRY
IPC: A61F2/82
Filed: 2003-10-10
Abstract: A stent for treatment of a body lumen through which a flow is effected on either side of a sphincter, said stent comprising one or more windings and having an inner core substantially covered by an outer core and including a first segment, a second segment, and a connecting member disposed between the segments. When the stent is positioned within a patient's urinary system, the first segment and second segments are located on either side of the external sphincter to inhibit migration of the stent while not interfering with the normal functioning of the sphincter. The outer coating comprises an absorbable material that provides temporary structural support to the stent. After absorption of substantially all the outer coating of the stent, the remaining relatively compliant inner core facilitates easy removal by the patient by pulling a portion of the stent that extends outside the patient's body for this purpose.

Title: Density-controlled particulate suspensions for foodstuff, cosmetic, pharmaceutical and other uses
Inventor: DING LI
IPC: A61Q5/02
Filed: 2003-11-26
Abstract: Stable and uniform distribution of gel beads or other particulate material, dispersed in a liquid medium can be obtained by including a density-reducing agent within the gel beads to provide the particle with a desired bulk density, for example a density close to that of the disperse liquid medium.  Suitable density control can prevent migration due to gravity leading to settling in storage. Gel beads formulated with agar are suitable for use in cosmetics and for inclusion in cosmetics formulating processes which may employ modestly elevated temperatures. Attractive and novel cosmetics bead suspensions are described. Additional to cosmetics, pharmaceutical, foodstuff and other applications are disclosed. Examples of suitable density~ reducing agents include very low density hollow polymeric microspheres and temperature-sensitive expandable thermoplastic microspheres.

Title: Improved adhesive-spreading unit, in particular for bonding machines
Inventor: CERCIELLO ANTONIO
IPC: B05C1/12
Filed: 2006-03-29
Abstract: An improved adhesive-spreading unit, in particular for bonding machines, of the type comprising a set of rollers (12, 18, 20), each of which rotates at a higher speed than the preceding one, the first roller (12) being in contact with a tank (16) of adhesive and the last roller (20) sliding in contact with a film (21) on which said adhesive is to be deposited, which said unit also comprises devices (23, 24, 30, 31) designed to distance said rollers from one another and bring them into contact when the film has been loaded into the machine, and that includes a single actuator unit (23, 24) for the movement of said rollers. Said actuator (23, 24), during the first stage of its travel, brings a rubber-clad roller (18) into contact with the first roller (12) that takes up adhesive from a tank, and during the second part of its travel moves said two rollers (12, 18) to bring the rubber-covered roller into contact with a third roller (20), which transfers the adhesive to the film and vice versa.      The result is a more compact unit which eliminates the need for two motors, as is the case with known units, because all the movements of the various parts are driven by a common actuator.

Abstract: Measurements are taken of moisture, BTU/lb (British Thermal Units per pound), ash, forms of sulfur, volatile material, grindability, and absorption properties of any of a wide variety of mine-run solid fuels. Using that information, a dry electromagnetic process technology has been developed that can be controlled and monitored to selectively alter and enhance solid fuel properties for the application in question. Specific changes include altering the mechanical structure and chemical composition of solid fuels such as coal, coal coke or petroleum coke, increasing the BTU/lb to optimum levels, decreasing all forms of sulfur, and decreasing ash, while maintaining the BTU/lb of the fuels. A new family of solid fuel designer coals not found in nature can be produced via these methods and apparatus.
