Patent CA-2140587-A1 (CA)
Title: Container bag
Inventor: PROFFITT ROBERT J
IPC: B65D88/16
Filed: 1995-01-19
Abstract: A container bag which comprises a body of flexible material having lifting loops across the corners thereof and baffles to maintain a square configuration is characterised in that a liner is provided sealed to the baffles.    The use of baffles in square configuration FIBC's has hitherto prevented the use of a liner since the baffles would prevent the liner fitting properly in each of the corners of the bag.  In accordance with the present invention the baffles within the liner and are sealed to it before the latter is affixed to the FIBC.    In this manner, an FIBC can be produced which has both baffles giving it a square configuration and a liner to prevent ingress of moisture  and air. The  liner taking  on the  'square' configuration imparts it to the FIBC as a whole.   The baffles may protrude from the liner and be attached to the FIBC walls, or they may be wholly within the liner. In either case, the liner will preferably be impervious to air and moisture and may be a polyolefin sheet material.

Patent CA-2147582-A1 (CA)
Title: Torsion bar assembly
Inventor: WARNER CHARLES E
IPC: E05F1/12
Filed: 1995-04-21
Abstract: A torsion bar assembly for a dishwasher door having a stainless steel torsion bar enclosed in an elongated stainless steel tube such that the bar rotates within the tube as the door is moved between an open and a closed position.  One end of the bar and tube are fixedly disposed in a rectangular boss which is fixedly attached to the dishwasher door; and a second end of the tube and bar are releasably disposed in a cylindrical boss which is welded to a door hinge.  The bosses are attached on opposite sides of the interior door panel, so that the torsion bar extends substantially the width of the door.  The torsion bar is protected from water by the corrosion-resistant tube, and by a pair of quad-rings which are disposed in recesses in the cylindrical boss.  The quad-rings prevent water from seeping through the boss and reaching the torsion bar.  When the ends of the torsion bar are disposed in the bosses, the bar is spaced within the tube to permit the bar to rotate independently of the tube.  This rotation builds up torque in the torsion bar.  This torque is released when the door is closed, to supplement the effort needed to close the door.

Patent CA-2150584-A1 (CA)
Inventor: OWENS N DOUGLAS
IPC: E05D15/26
Filed: 1995-05-31
Abstract: An anti-float system for operable partitions in a movable wall system.  The anti-float system includes first and second camming assemblies, each including a trolley camming surface, cooperatively positioned along the operable partition track.  Preferably both of the trolley camming surfaces are spring biased to camming positions where they define a passageway through which a portion of the trolley passes when the trolley moves along the track.  The passageway is narrower than the width of the trolley portion.  When the trolley portion enters the passageway while traveling in the wall extending direction, the trolley portion engages the trolley camming surfaces and forces the surfaces outward from their camming positions against a resistance provided by the biasing springs in order for the trolley to pass.  The camming assemblies are also movable from a camming alignment to a retracted alignment when the trolley portion travels in the wall stacking direction through the passageway.

Title: Controlled release growth hormone containing microspheres
Inventor: AUER HENRY
IPC: A61K9/26
Filed: 1993-12-02
Abstract: Growth hormone polymeric controlled release systems are described wherein the growth hormone retains good biological activity and is released over an extended period of time following administration by injection. In the preferred embodiment, human growth hormone polymeric microspheres are made using very cold temperatures to freeze the polymer-growth hormone mixtures into polymeric microspheres with very high retention of biological activity and material. Sustained release of biologically active growth hormone is achieved when the microspheres are tested in vitro, extending over a period of greater than one day to several months. Altered release can be achieved by inclusion of degradation modifiers, pore forming agents, and stabilizers of the growth hormone.

Title: Hydraulic system for dynamic braking and secondary steering system supply
Inventor: SIMMONS GERALD PAUL
IPC: B60T13/16
Filed: 1995-09-08
Abstract: In certain machines, such as construction equipment, it is desirable to provide a supplemental fluid supply for hydraulic steering systems to maintain sufficient fluid flow should a failure occur in the primary fluid supply.  It is also desirable to provide retarding or dynamic braking to help control speed of the machine when operating downhill with a heavy load.  A ground driven pump is provided to supply fluid to a selector valve for selectively directing the output of the ground driven pump to a steering system or a dynamic braking system.  The selector valve is responsive to pressure in the steering system to direct flow from the ground driven pump to the steering system when the pressure drops below a predetermined level.  The operator may selectively direct flow from the ground driven pump to the dynamic braking system when dynamic braking is needed.  A dynamic braking valve may be operator controlled to regulate the degree of dynamic braking required to maintain the desired machine speed under specific operating conditions.  In this manner a supplemental supply is provided which may be selectively directed to the steering system or the dynamic braking system.

Title: Method of producing sugars using strong acid hydrolysis of cellulosic and hemicellulosic materials
Inventor: CUZENS JOHN E
IPC: C13B20/14
Filed: 1994-03-25
Abstract: An economically viable method for producing sugars using concentrated acid hydrolysis of biomass containing cellulose and hemicellulose is disclosed. The cellulose and hemicellulose in the biomass are first decrystallized and then hydrolysed to produce a hydrolysate containing both sugars and acid. Silica present in the biomass can then be removed for further processing.  The remaining solids are then subjected to a second decrystallization and hydrolyzation to optimize the sugar yields. An improved method for separating the sugars from the acid in the hydrolysate is also disclosed. The resulting sugar stream can then be fermented, using an improved method which allows both hexose and pentose sugars to be fermented simultaneously.

Title: Hammer drill with inclined clutch plate
Inventor: DIBBERN JOHN E JR
IPC: B25D16/00
Filed: 1995-09-19
Abstract: A hammer drill may be set for operation in a hammer mode or a drill mode through a mode selector 41.      In the drill mode, output shaft 25 is locked in a forwardly biased position and is rotatably driven through spur gears 29, 31. In the hammer drill mode, output spindle 25 is rotatably driven by spur gears 29, 31 and is axially reciprocated by hammer clutch 55. An output clutch plate 57 of clutch 55 is axially and rotatably fixed to spindle 25 and has a first annular tooth array 63 on rear face 61. An input clutch plate 59 of clutch 55 is axially and nonrotatably fixed in tool housing 15 and has a second annular tooth array 67 on a forwardly inclined front face 65. Tooth arrays 63, 67 are engageable in the hammer mode. Output clutch plate 57 is shiftable in use in the hammer mode to position the rear face 61 generally parallel to the front face 65. The forward inclination of input clutch front face 65 compensates for the movement of output clutch rear face 61 from a no-load to a load position so that the faces 65, 61 are generally parallel in use.      By ensuring parallelism of the clutch faces 65, 61 in use, clutch 55 has a significantly improved life.
