Patent CA-2280534-C (CA)
Inventor: CARRIERE FRANCOIS
IPC: A61K9/22

Granted: 2003-08-19
Abstract: A process for the industrial manufacture in an aqueous medium of a slow- release excipient consisting mainly of cross-linked amylose having controlled release properties, for use in the preparation of tablets or pellets. A starch containing a high amount of amylose (high amylose starch) is first subjected to a gelatinization. The gelatinized high amylose starch is then cross-linked with 1 to 5 g of a cross-linking agent per 100 g of dry-based gelatinized high amylose starch in an alkali medium, thereby forming a reaction medium containing a reaction product consisting of a cross-linked high amylose starch slurry. The obtained reaction medium is neutralized, thereby forming by- products mainly consisting of salts, which are removed from the reaction medium. The recovered cross-linked high amylose starch slurry is then subjected to a thermal treatment at a temperature of at least 60 ~C and the thermally treated product is dried to obtain the requested slow release excipient. This process is economical and industrially advantageous since it is carried out in an aqueous medium.

Abstract: The invention relates to a snowboard (100), which includes upturned nose (10 8) and tail (112) portions and a central section (110). Two mounting zones (133 and 135), intended to secure the boots (132 and 134) , are located on the central section (110). The central section (110) also includes front (118) and rear (120) cambers, which enable the user to more easily control the snowboard (100). Users of snowboards (100) also have a natural tendency to lean in the direction of travel of the snowboard (100), which shifts the position of the rider's center of gravity slightly forward of the board's midpoint. To compensate, the front camber (418) may be made longer, taller and thicker than the rear camber (420). The front and rear cambers may also include mini-cambers (442 and 444) to further improve the user's ability to control the snowboard (400).

Abstract: A method and apparatus for forming a tube-encased fiber grating includes an optical fiber (28) which is encased within and fused to at least a portion of a glass capillary tube (120) and a substantially transparent index-matching medium (122), such as an optically flat window, having an optically flat surface (126) adjacent to the tube (120). A substantially transparent index-matching intermediate material (e.g., UV transparent oil) (124) is used between the window (22) and the tube (120) to substantially eliminate the interface between the tube (120) and the medium (122). A  pair of writing beams (26, 34) are incident on and pass through the medium (122), the tube (120) and intersect and interfere in a region (30) on the fiber (28). Also, the width (Wb) of the writing beams (26,34) may be set to be less than the width (Woil) of the intermediate material (124) to eliminate surface damage (ablations) of the tube (120). Alternatively, the medium (122) may have a geometry to eliminate surface ablations (e.g., a collar shape) and/or to match the shape of the tube (120). More than one grating or pair of gratings may be written in the tube-encased fiber or one or more gratings may be formed in multiple fibers (28, 250) encased in the tube (120). Further, high intensity writing beams (26, 34) on the fiber (28) may be achieved by having the medium (122) have a predetermined thickness (T).

Title: Apparatus and method for dispensing small quantities of particles
Inventor: MACMICHAEL BRUCE
IPC: G01G13/06
Filed: 2000-11-03
Granted: 2012-05-29
Abstract: There is disclosed an apparatus and method which is capable of dispensing very small (typically less than 5 mg) quantities of particles to a high accuracy in a repeatable way and without undue wastage. Also, the need for advanced particle formulation is reduced. The apparatus comprises a closed loop control system which uses an electro-mechanical actuator to deliver impact energy to a supply of particles initially held on a sieve in a hopper. The impact energy causes a small number of particles to fall through the sieve and onto a weight measuring balance. The weight obtained is scrutinised by a processor to see if further actuations are required. In preferred embodiments, the energy of actuation is varied in accordance with the rate of dispensation calculated by the processor. Also, a correction amount can be obtained to take account of the fact that the balance can take a considerable amount of time to settle to its final value.
