Title: Intraocular lenses
Inventor: STOY VLADIMIR A
IPC: A61F2/16
Filed: 1987-11-23
Granted: 1994-01-25
Abstract: ABSTRACT OF THE DISCLOSURE    There  is provided a novel  intraocular lens and mode of insertion therefore.   The lens  is of conventional  shape and dimensions but is made of polymeric material having a softening point in the range of body temperature.   The lens, prior to insertion is dimensionally reduced to enable introduction thru a small  incision  by  compression  or  by  axial  extension.    The deformed lens is frozen in this configuration by cooling the lens below its softening temperature.   The cooled, deformed lens is then inserted into the eye.  The action of body heat, optionally supplemented by various non-harmful methods, permits the lens to regain its original configuration within the eye.

Title: Fabrication technique for low-loss fused taper directional couplers and pressure sensor produced thereby
Inventor: BILODEAU FRANCOIS
IPC: G02B6/28
Filed: 1988-01-11
Granted: 1992-10-20
Abstract: ABSTRACT             A method of forming a single mode biconical fiber optic coupler comprising holding 2 or more optical fibers parallel to and in contact with each other at spaced apart locations, exerting equal tension in opposite directions to the fibers at said spaced apart locations to stretch the fibers, fusing the fibers over a waist region, and scanning the tip of a flame from a microtorch back and forth along the fibers at a speed which is at least five times the speed of stretching of the fibers.  This results in an overcoupled low loss coupler, a pressure or a temperature sensor, comprised of at least a pair of monomode optical fibers fused and parallel at a stretched waist portion, each having biconical tapers at opposite ends of the waist portion, the cupler having exhibited at least about 500 power transfer cycles during stretching formation of the waist portion.
Patent CA-1313775-C (CA)
Title: Marine instrument
Inventor: BOUCHER STEPHEN G
IPC: G01P5/00
Filed: 1988-01-27
Granted: 1993-02-23
Abstract: MARINE INSTRUMENT Abstract of the Disclosure A through-hull speed sensor of the magnetized paddlewheel sensor type wherein a paddlewheel is rotatably supported in a cavity adjacent a magnetic sensing device which generates electrical pulses corresponding to paddlewheel speed as the wheel rotates when the vessel moves through water.  The sensor has improved low speed characteristics provided by a housing which extends the paddle wheel into the water below the hull.  The bow o f the housing provides a new leading edge, generating a smaller thickness boundary layer at the paddlewheel, so that the paddles project beyond the layer at low speeds.  High speed performance is improved by having a high ratio o f paddle fore-to-aft drag coefficient shape; keeping the periphery of the paddlewheel hub within, or flush with, the bottom of the cavity; a low paddle projection versus paddlewheel radius ratio; and by keeping the ratio of paddle cross-section versus available cavity cross-sectional space within an optimum range.

Title: Distributor for distributing liquid in an exchange column
Inventor: MICHELS CHRISTOPH
IPC: F15B15/00
Filed: 1988-03-01
Granted: 1991-09-24
Abstract: ABSTRACT OF THE DISCLOSURE      The distributor has a plurality of distribution channels with outlet openings in the lower region for expelling streams of liquid against opposed impact walls in order to form descending liquid films on the impact walls.  The impact wall  are spaced from the side walls of the channels by a distance greater than the thickness of the liquid film formed on the impact walls.  The kinetic energy of the liquid streams is relied upon to form the liquid film in parabolic-like shapes. Screening walls may also be disposed in opposition to the impact walls to preclude the entrainment of liquid in the rising vapor phase.

Patent CA-1327456-C (CA)
Inventor: RYDE MICHAEL J
IPC: B60H1/32
Filed: 1988-04-27
Granted: 1994-03-08
Abstract: ABSTRACT OF THE DISCLOSURE    A multicompartmented road vehicle e.g. a six-lane delivery truck has a separate refrigerator system for each lane, governed by a separate thermostat in each case.  The corresponding condensers are conveniently arranged in a bank or accumulation.  A common generator, preferably supplied with a sequencing arrangement to prevent start-up overload or casual overload generates the electrical power to drive the refrigeration systems.  The cost of initial installation is an acceptable proportion of the cost of a heavy truck, the cost of maintenance is less than for maintenance of complex valving, ducting and internal prioritizing logic systems as in interconnected refrigeration systems of the prior art, and the mass and size of the installation is again compatible with the truck size and shape.  Thus the normally counterindicated provision of separate rather than shared systems has unexpected advantage.  Also, the single on-board generator would be powerful enough to operate loading and unloading equipment when desired.

Title: Air suspension apparatus
Inventor: SCHULT LESLIE H
IPC: B62D53/08
Filed: 1988-06-29
Granted: 1992-06-09
Abstract: ABSTRACT           An air suspension apparatus is disclosed for use with the fifth wheel connection between a tractor and semitrailer.  The apparatus includes upper and lower frame sections that are connected by a hinge mechanism for relative pivotal movement.  An inflatable air bag is operably disposed between the upper and lower frame sec-tions, having a low ratio of effective surface area to internal volume and hence a very low profile.  An air reservoir defined by tubular framework surrounds the air bag and has an internal volume approximating that of the air bag.  The air bag and reservoir are connected by an air line with a very small cross sectional area as com-pared to the surface area of the air bag.  The reservoir and interconnecting air line effectively damp vibra-tional energy in the air bag as the tractor and semi-trailer move over the highway.

Granted: 1994-05-17
Abstract: ABSTRACT OF THE DISCLOSURE              A brace supports a form during placing of concrete and collapses into a compact state after use. The brace has a pair of channeled members. One channeled member attaches to the form; the other is anchored to a horizontal surface. A pivot joint between first ends of the channeled members allows them to pivot to and from an orientation in which they are overlaid with their channels facing towards one another. A telescopic member controls their relative angular orientation and consequently the orientation of the form. The telescopic member has inner and outer sleeves which are connected with pivot joints to second ends of the channeled members. The inner sleeve is formed with several transverse passages, and the outer sleeve has a single transverse passage that can be aligned with any passage of the inner sleeve. A locking member inserts through the aligned passages to fix the length of the telescopic member and can be removed to permit separation of the sleeves. When separated, the sleeves pivot into the channels of the channeled members. The channeled members can then be pivoted onto one another, producing a relative compact assembly.
