Abstract: MOUNTING BRACKET ARRANGEMENT FOR ALIGNING OPTICAL SYSTEM COMPONENTS          ABSTRACT      A mounting bracket arrangements for an optical component (10) which must be precisely oriented on a base structure (12) and held securely against vibrations, the arrangement including a bracket assembly (14) having first and second bracket plates (24, 26) extending orthogonally with respect to each other. The component (10) is secured to subplate (20) in turn attached to the first bracket plate (24) with a pivot screw (38) and a pair of locking screws (34, 36) so as to enable pivoting adjustment, secured by tightening all of the screws. The second bracket plate (26) is attached to the base structure (12) by a pivot screw (56) and a pair of locking screws (52, 54) so as to enable pivoting adjustment, thereafter secured by tightening all of the screws. A torque plate (50, 62) is installed beneath each set of locking screws to prevent disturbing the adjusted position as the locking screws are tightened. Pairs of aligned holes (68, 70, 74, 76) are formed in the subplate (20) and first bracket plate (24) and second bracket plate (26) and base structure (12) to enable a tool inserted in the holes to be used to adjust the position of the parts.

Patent CA-2049443-A1 (CA)
Inventor: YOUNG DOUGLAS L G
IPC: D21D5/16
Filed: 1991-08-19
Abstract: An apparatus, for pressurized screening of a fiber/liquid suspension to separate the fibrous fraction into an accepts portion and a rejects portion, has a housing having an inlet with a heavy and large material trap, an accepts outlet, a rejects outlet, and a dilution liquid inlet.  A hollow cylindrical screen having an open top and bottom communicates with the fibrous suspension inlet chamber and the rejects outlet chamber.  Accepts fibers in the suspension pass through apertures in the screen to the accepts chamber and are discharged through the accepts outlet.  Rejects discharge through the rejects chamber.  A rotor having at least four regions, a closed top, and a bottom mounted drive mechanism is coaxially mounted within the screen.  Hydrodynamic pulses are induced in the suspension in the screening region by a pattern of bumps and/or depressions impressed upon the rotor surface.  The fibrous suspension is maintained at a relatively constant consistency within the screening region by the pumping action of the rotor and by providing dilution liquid to counteract thickening of the suspension.  A dynamic bar screening device directs stones and other large objects out of the fluid stream and into an annular trap and also deflocculates the suspension.

Title: Crimped continuous filament yarn with color-point heather appearance
Inventor: COONS ANDREW M
IPC: D02J1/08
Filed: 1991-09-20
Abstract: A process for making a heather-dyeable or precolored heather yarn product comprises supplying a first crimped continuous filament yarn in the form of a loose matrix substantially free of filament entanglement and a second crimped continuous filament yarn which is differentially dyeable or precolored with respect to the first yarn.  The second yarn is fed through a first entangling or interlacing zone and exposure of the second yarn to a fluid jet in the first entangling zone is randomly controlled to produce a color-point yarn product as the second yarn exits the first entangling zone, in which the color-point yarn product has relatively compact nodal regions of high entanglement of the filaments of the second yarn separated by bulkier regions of the same filaments relatively free of entanglement.  The first yarn and the color-point yarn product are then fed through a second entangling zone which randomly entangles filaments of the yarns from yarn to yarn  and in which yarn-to-yarn filament commingling is substantially prevented within the nodal regions of the color-point yarn.  An apparatus for performing the process includes a randomly controllable fluid valve supplying fluid to the fluid jet in one embodiment, and a randomly controllable yarn guide to move the yarn into and out of the fluid jet in another embodiment.

Title: Interdigitation-fusion liposomes and gels
Inventor: BONI LAWRENCE T
IPC: A61K47/24
Filed: 1991-01-11
Abstract: This invention relates to interdigitation-fusion (IF) liposomes and gels. These liposomes and gels capture high solute to lipid ratios, including bioactive agent. This invention also relates to the discovery that the fusion of liposomes to produce IF gel and liposomes according to the present invention is size dependent. The present invention also relates to a method for producing IF liposomes and gels. In the method of the present invention, sized liposomes formed by sonication, extrusion or alternative processes are fused in the presence of ethanol or other suitable inducer. This process results in a composition of the present invention in gel form. To produce liposomes, the gels are exposed to a temperature usually but not necessarily above the transition temperature (Tm) of the lipid used. The temperature required by the methods of the invention is that temperature which induces a change in the material properties of the mixture. The inducer may also be removed. The result is a composition comprising liposomes containing high solute to lipid ratios. The IF liposomes and gels of the present invention may be used in combination with numerous solutes, especially including bioactive agents.
