Patent CA-2159322-A1 (CA)
Title: Lubricating oil dewaxing using cold solvent recycle process
Inventor: GOULD RONALD MICHAEL
IPC: C10G73/04
Filed: 1994-04-21
Abstract: A process for solvent dewaxing a waxy oil feed to obtain petroleum oil lubricating stock comprising the steps of contacting a warm waxy oil feed by indirect heat exchange first with cold filtrate, then with refrigerant to crystallize and precipitate the wax in the oil feed to form an oil/solvent/wax mixture. The oil/solvent/wax mixture is diluted with cold solvent to adjust the viscosity of the mixture and the mixture is filtered to remove the wax from the cold oil/solvent/wax mixture. A cold wax cake is recovered and a cold oil/solvent filtrate stream is recovered. The cold ail/solvent filtrate stream is fed, at the filtration temperature, to a selective permeable membrane. The membrane selectively separates the cold filtrate into a cold solvent permeate stream and a cold filtrate stream which contains the dewaxed oil and the remaining solvent.
Patent CA-2161745-A1 (CA)
Inventor: FRITZ ALAN H
IPC: B05B1/30
Filed: 1995-10-30
Abstract: A two component external mix spray gun having a pneumatically operated valve for controlling the injection of a catalyst into pattern shaping air passages in the gun. The catalyst is contacted with the atomized fluid externally to the spray gun. A trigger sequentially operates air and fluid valves to provide atomization air and pattern shaping air prior to opening the fluid valve. The pneumatic catalyst valve is responsive to an increase in the air pressure downstream from the air valve to inject the catalyst into the pattern shaping air prior to the opening of the fluid valve. The catalyst impinges on the atomized fluid externally to the spray gun along with the pattern shaping air. The invention may be incorporated in either a hand held spray gun with a manual trigger or an automatic spray gun with a controller.

Title: Quartz nozzle for fixed head burner
Inventor: MARCHIONDA JOHN PAUL
IPC: F23D14/32
Filed: 1995-12-19
Abstract: In a fixed head burner (13), which may be used in the manufacture of optical fibers and preforms for optical fibers, a machined quartz nozzle (10) is provided for insertion into a threaded aperture (14) of the fixed burner head (13), the quartz nozzle (10) being sized to provide sufficient space between the quartz nozzle (10) and the burner head (12) to allow for relative differences in thermal expansion and contraction to prevent stress fracture of the quartz nozzle (10).  A seating surfaces (85) is machined on the quartz nozzle (10) for contact with a machined surface (90) of the burner head (12), and the quartz nozzle is held in place by a spring (18) placed behind the quartz nozzle (10), the spring (18) being held in place by a threaded end cap (24).  The secure retention of the quartz nozzle (10) within an aperture (14) in the burner head (12) is further aided by the pneumatic pressure of gases applied to a rear surface (20) of the quartz nozzle (10).  During exposure to high temperatures, erosion of the quartz nozzle (10) may occur, however, the erosion by-products do not contaminate a preform or an optical fiber being heated by the burner head (12).

IPC: A01N25/34
Filed: 1996-07-15
Abstract: A planting system involving a non-damaging stimulus (3) which is placed in the vicinity of a propagule (2) causes a naturally defensive substance (5) to be produced by the propagule. This substance may exist within an encapsulant (1) for a period of time so that the propagule may have enhanced disease control until it develops sufficiently to fend for itself. In one embodiment a large encapsulant surrounds a potato tuber. This encapsulant may include chitin to cause the release of chitinase through intermediate stimulants such as mRNA and activated carbon to absorb or release particular substances. The encapsulant is bound through the use of pentosan which acts with flaked chitin to achieve an outer casing and further protect the propagule both mechanically and chemically.

Title: Apparatus for delivering printed products to a further-processing location
Inventor: KELLER ALEX
IPC: B65H29/66
Filed: 1996-07-24
Abstract: Folded printed products are conveyed in a first imbricated formation up to a stop by a first conveying device. In the first imbricated formation each printed product rests on the following printed product with its leading bottom edge formed by its folded edge. At the stacking location formed by the stop, the printed products are stacked up in layers to form an intermediate stack. The uppermost printed product is moved by a lifting member into the conveying region of a removal conveyor and then to a further-processing station. The removal conveyor has a conveying wheel that is driven synchronously with the lifting member, and a pressing-on member that, as a strand of a belt conveyor, is assigned to a part of the circumferential surface of the conveying wheel. The conveying wheel and the pressing on member together form a guidance gap for the printed products. The conveying wheel is provided with a plurality of cutouts that are distributed uniformly on the circumferential surface. The folded edges of the printed products are introduced individually into the cutouts by the lifting member. The printed products are then directed into the guidance gap by virtue of the rotation of the conveying wheel. A second imbricated formation is formed, in which, once again, each printed product rests on the following printed product and the leading folded edge is located at the bottom.

Filed: 1996-08-13
Abstract: A stereo camera allows a rapid photographing and stereo effect correcting function to be compatible by providing a mechanism for automatically adjusting a distance between optical axes of photographing lenses and a manual adjusting mechanism.  Lens shifting cams are provided symmetrically at a base frame of the stereo camera, and urged by a spring so that the inner surfaces of the lens shifting cams are pushed upon the right and left lens boards independent from each other.          The lens shift cams are formed to automatically focus the photographing ranges of the right and left photographing lenses of a focal distance irrespective of the feeding amounts of the photographing lenses, and the distance between the optical axes are automatically adjusted being interlocked to the focal adjustment.  If the subjects of remote range and close range are mixed, the manual adjusting lens shift knob is operated to move the lens boards in approaching direction by lens shifters to be finely adjusted to the optimum distance between the optical axes.
