Abstract: A suspender system includes a pair of suspenders for holding work trousers. At the front end of each suspender strap is a patch of the hook component of a hook and loop fastener. A similar patch of hook component is found at the back end of each strap. The waistband of a pair of trousers has the mating loop component of the fastener stitched to its inside. The suspenders are therefore attached to the trousers without the use of conventional metal clips, which can damage surrounding objects which they contact and can damage and deform the trouser waistband.

Title: Methods for use of mpl ligands with primitive human stem cells
Inventor: YOUNG JUDY C
IPC: A61K35/12
Filed: 1996-10-29
Granted: 2009-01-20
Abstract: Myeloproliferative leukemia receptor (mpl) ligands, such as thrombopoietin, act on a primitive subpopulation of human stem cells having the characteristics of self-renewal and ability to give rise to all hematopoietic cell lineages. Thrombopoietin supports both megakaryocytic differentiation and primitive progenitor cell expansion of CD34+ and CD34 sub-populations (CD34+Lin-, CD34*Thy-1+Lin-, and CD34+Lin- Rh12310). Thrombopoietin also stimulates quiescent human stem cells to begin cycling. Thus, mpl ligands are useful for expanding primitive stem cells for restoration of hematopoietic capabilities and for providing modified human stem cells for gene therapy applications.

Title: Simplified keyboard and electronic musical instrument
Inventor: PAWLOWSKI J THOMAS
IPC: G10H1/20
Filed: 1996-06-26
Granted: 2002-08-13
Abstract: Disclosed is an electronic musical instrument comprised of operators organized in repeating patterns of seven. The operators are electronically interpreted to correspond only to the valid notes of a selected scale.      The repeating patterns of seven notes directly corresponds to the vast majority of music theory and thus constitutes an enormous simplification in the art of learning, performing and composing music. The present invention enables users of the electronic musical instrument to master chord and note progressions in any scale and mode by learning only a single set of note patterns, in contrast to the myriad scales, chord and note patterns which must be learned on traditional keyboard and pedal devices.

Granted: 2005-01-04
Abstract: A modular gas control device for use with a compressed gas cylinder (111) comprises a primary module (152) and a secondary module (252) mounted on the primary module. The primary module comprises a first supporting body (154) having a first main gas flow path (155) through the body. The supporting body has input connecting means (156) for mounting the body on the cylinder (111) and connecting the gas flow path (155) to communicate with the gas cylinder through a first flow path (157). Pressure reducing means (166) provides gas in the flow path at a lower pressure than in the container. Output connecting means (170) downstream of the pressure reducing means provides a low pressure outlet from the main gas flow path. A high pressure shut off valve (164) is positioned upstream of the pressure reducing means, and filling means (161, 160) allows filling of the cylinder with compressed gas through the input connecting means (156) along a second flow path (159) separate from the input flow path (157). The secondary module (252) has a corresponding supporting body (254) and main flow path (255) and corresponding output connecting means (270) and corresponding input connecting means (256) for mounting the secondary module (252) on the primary module (152). The supporting body (254) of the secondary module has a combination of two or more functional components comprising means for measuring and/or varying parameters of gas flow in the second supporting body, and/or for switching and/or venting and/or mixing gas flow in the second supporting body.

Granted: 2005-02-15
Abstract: The present invention relates generally to an apparatus for mixing or dissolving a particulate solid or gel in a liquid to form a solution of a substantially homogeneous concentration. In one example, the apparatus (10) comprises a vessel (18) having a cylindrical portion (20) formed integral with a large diameter end of a conical frustum portion (22). The vessel (18) includes a series of liquid inlets (24A, 24B, 24C) and a solution outlet (26). The liquid inlets (24A, 24B, 24C) are located in a wall of the cylindrical portion (20) and conical frustum portion (22), and the solution outlet (26) is formed at a small diameter end of the conical frustum portion (22). An elbow-shaped nozzle (28A, 28B, 28C) is connected to each of the liquid inlets (24A, 24B, 24C), the nozzles (28A, 28B, 28C) designed to direct a flow of liquid parallel to an inside surface of the vessel (18). The apparatus (10) also comprises a venturi (30) located adjacent the outlet (26) so as to create a low pressure zone downstream of the venturi (30) and thus suck or draw liquid (14) or solution (16) from the vessel (18).

Title: Training weapon system
Inventor: FRANZEN ARNE
IPC: F42B8/10
Filed: 1998-05-29
Granted: 2002-02-19
Abstract: The invention relates to a training weapon system for a portable recoilless anti-armour weapon of the type which comprises a sub-calibre insert barrel (1) arranged in the bore of the launching barrel of the full-calibre weapon. In order to improve the accuracy of the system and make it more safe as well as less expensive when compared to previous systems of this type, the sub-calibre insert barrel (1) has a rifled bore to make the training projectile spin stabilized. The forward aligning member (5) for centering the insert barrel (1) is engaging the ridges of the rifles in the rifled portion of the barrel in the recoilless full calibre weapon. By such an arrangement it can be avoided that length tolerances give rise to undesired radial deviations which might result in a mis-alignment of the insert barrel (1) within the gun bore.  This could happen with the forward aligning member engaging the conical, smooth-bored firing chamber in the barrel.

Patent CA-2274417-C (CA)
Inventor: BLUMTHAL WILLIAM MICHAEL
IPC: F25D3/11
Filed: 1999-06-07
Granted: 2003-03-18
Abstract: The method of the invention is based on the comparison of local vapor concentrations at the inlet and outlet refrigeration ports and taking action based on that comparison. Control apparatus incorporating the invention is installed inside a refrigeration enclosure, adjacent to a port, preferably at the lowermost port. If the enclosure contains multiple ports at similar height, then each port has a form of the control apparatus attached to it. The control apparatus adjusts a flow of vapor leaving the interior of the enclosure. The control apparatus includes a duct assembly and a blower system. The bottom portion of the duct assembly is a tunnel enclosure through which a conveyor belt passes. Connected to an inside edge of the tunnel enclosure is a duct that extends upward from the conveyor belt. A blower for this duct either sucks vapor away from the conveyor belt or blows vapor from the enclosure interior toward the belt.      Regardless of the flow direction, a vapor curtain forms inside the tunnel enclosure and represents a transitional region from all vapor to all air. Control of the blower for the duct assembly is based on vapor concentrations in the tunnel enclosures adjacent to each port. A microprocessor compares measured concentration levels and alters the blower motor frequency in such a manner as to minimize the difference in concentration levels at each port.
