Title: Process for glucan preparation and therapeutic uses of glucan
Inventor: KELLY GRAHAM EDMUND
IPC: A61K36/00
Filed: 1996-03-13
Abstract: A process for the production of .beta.-(1,3)(1,6) glucan from a glucan containing cellular source is described, together with compositions and uses/methods of treatment involving glucan. The process of the invention comprises the steps of: (a) extracting glucan containing cells with alkali and heat, in order to remove alkali soluble components; (b) acid extracting the cells of step (a) with an acid and heat to form a suspension; (c) extracting the suspension obtained of step (b) or recovered hydrolyzed cells with an organic solvent which is non-miscible with water and which has a density greater than that of water separating the resultant aqueous phase, solvent containing phase and interface so that substantially only the aqueous phase comprising .beta.-(1,3)(1,6) glucan particulate material remains; wherein the extraction with said organic solvent provides separation of glucan subgroups comprising branched .beta.-(1,3)(1,6)-glucan, and essentially unbranched .beta.-(1,3) glucan which is associated with residual non-glucan contaminents; and (d) drying the glucan material from step (c) to give microparticulate glucan.

Patent CA-2226475-A1 (CA)
Inventor: LAMB JOHN B
IPC: E03F5/16
Filed: 1998-01-08
Abstract: An oil trap for a catch basin comprises a continuous trough which contains one or more oil-absorbing socks and has a plurality of holes formed through its bottom.  The trough is adapted to be mounted in a catch basin so that a substantial portion of the water entering the catch basin will fall into the trap and come into contact with the oil absorbing socks before it drains out of the trap.  When the water comes into contact with the socks, oil contaminants contained in the water are absorbed by the socks, such that the water leaving the trap contains less oil contaminants than when it entered the trap.

IPC: G04F10/00
Filed: 1996-09-27
Abstract: An apparatus and method for monitoring and motivating user compliance for orthodontic headgear (24) of the type using a linear spring-force module (22).  The spring-force module (22) includes first (38) and second opposite attachment members that are interconnected to provide spring tension when moved linearly apart. A position sensor (16, 18, 19) detects linear movement between the attachment members. A microprocessor (12) receives signals from the position sensor to determine wear duration, force magnitude, and whether such movement is sufficiently variable to be biological in origin or is attempted mimicry. Multiple determinations made by the processor are recorded over time to provide an evaluation of headgear wear compliance and to provide ongoing motivation for user compliance.
Patent CA-2234590-A1 (CA)
Title: Centrifugal jig
Inventor: COSTIN C PATRICK
IPC: B03B5/22
Filed: 1998-04-09
Abstract: An improved jig screen 10 for a centrifugal jig includes a recovery zone 30 and a stratification zone 20 adjacent to one another. The stratification zone 20 is constructed to prohibit outward radial passage of slurry particles while permitting fluid pulsations to be imparted to the slurry during jig screen 10 rotation. The stratification zone 20 axially leads to the recovery zone 30. The recovery zone 30 has openings permitting passage of particles in the slurry and through which fluid pulsations are directed to the slurry during jig screen 10 rotation. The combination of applying centrifugal force and fluid pulsations to a pre-stratified slurry more effectively separates the heavy particles passing through the recovery zone 30 of the jig screen 10 from the lightweight particles discharged at its exit end.

Title: Device for collecting a blood sample from a plastic segment tube
Inventor: SAGSTETTER WILLIAM E
IPC: A61J1/14
Filed: 1997-03-05
Abstract: A device (10) for collecting a blood sample from a plastic segment tube (50) into a receptacle (60) uses a cylindrical housing (11) containing a hollow needle (15) to puncture the segment tube (50) as it is inserted into the upper port of the device (10). A series of ribs (14) with tapered medial edges are arranged in a radial pattern around the needle (15) within the upper port to guide and support the segment tube (50) as it is inserted. The ribs (14) are separated by slots (13) that also guide the sealed end (51) of the segment tube (50). An annular recess (16) around the lower port of the device (10) holds the rim of the receptacle (60) and allows blood released by the punctured segment tube (50) to drain into the receptacle (60). The annular recess (16) accommodates a wide range of test tube diameters, and exerts only a downward force on the rim of the receptacle (60) when a segment tube (50) is inserted into the upper port of the device (10).
