Title: Intraocular lens folder
Inventor: VAN NOY STEPHEN J
IPC: A61F9/007
Filed: 1994-01-18
Abstract: An intraocular lens folder (10) having a generally planar, open frame (12) in the shape of a rounded "A" with a rimmed, open head (14) at die top of the "A". The base of the "A" forms a pair of opposing legs or handles (16) that join to form a hinge (23) at the crotch where the handles attach to the head. The hinge allows the handles to be squeezed together and yet spring apart when released. Squeezing the handles causes the top edge (20) of the head rim (18) to compress and move toward the hinge. The open head contains a plurality of projections terminating in open, relieved jaws (24, 26, 28) into which the IOL  is placed. The location of the projections is such drat when the handles are squeezed together and die rim moves toward the hinge, two of the jaws move toward each other, causing the IOL to be folded in half.

Patent CA-2160296-A1 (CA)
Title: Co-adhesive system for bonding wood, fibers, or agriculture based composite materials
Inventor: SLEETER RONALD T
IPC: C08L97/02
Filed: 1995-10-11
Abstract: The invention provides an adhesive system comprising a blend of resin and a co-adhesive conjugated triglyceride, which is especially well suited to bonding composite panels such as oriented strand board, particle board, plywood, MDF, hardboard, and similar panels. The resin is a fast acting bonding material which forms a mat of fibers into a self sustaining panel within a time limit during which a press may be economically utilized.      The triglyceride acts slower so that, after the panel is formed, there is enough time to penetrate the fibers to a depth that results in a superior bonding.

Patent CA-2160824-A1 (CA)
Title: Locking pin apparatus
Inventor: ROBINSON HOWARD W
IPC: E02F9/28
Filed: 1995-10-18
Abstract: A locking pin for use captively retaining a tooth on an adaptor portion of an excavating tooth and adapter assembly has a primary wedge member with an integral spring extending upward from the member's distal end. A first positive stop means extends from the wedge member while an opposing second positive stop means extends from the integral spring. After insertion, the locking pin prevents separation of tooth from adapter portion while the first and second positive stop means prevent accidental loss of the locking pin from the assembly. To remove the locking pin, a force sufficient to separate the first positive stop means from the pin is exerted to drive the pin from the assembly. In another embodiment, the integral spring extends from a lateral surface of the locking pin. In another embodiment, the locking pin comprises stop means which are radially extendable by spring means. In another embodiment a non-integral spring is attached to the locking pin and allows for the use of a different material for the spring.

Patent CA-2172798-A1 (CA)
Title: Method to produce cyclic esters
Inventor: VERSER DAN W
IPC: C08L67/04
Filed: 1994-09-13
Abstract: Disclosed is a novel integrated process for production of cyclic esters which includes recovery of starting materials, such as lactic acid from a dilute aqueous lactic acid-containing solution, by solvent extraction. The starting materials are then formed into cyclic esters by removal of water wherein the concentration of higher molecular weight oligomers is maintained below about 20 wt% of the reaction composition. The process further includes providing a recovery solvent for the reaction composition and separating the cyclic esters from the starting materials and higher molecular weight oligomers by liquidliquid equilibrium separation. The present invention is further directed toward independent novel unit operations of the overall process. The present invention provides for the efficient production and recovery of cyclic esters due to integration of the various unit operations by use of appropriate solvents and recycle streams. In addition, high rates of conversion of starting materials and high rates of selective production of cyclic esters are achieved by appropriate control of process parameters.

Title: Drain-and-fill methods and apparatus for automotive cooling systems
Inventor: CREERON RICHARD F
IPC: F01P11/02
Filed: 1996-08-09
Abstract: A drain-and-fill machine is disclosed that can accommodate a cooling system having an inlet-side thermostat. The drain-and-fill machine includes a reservoir of fresh or recycled antifreeze/coolant and a reservoir to receive used antifreeze/coolant.  The drain-and-fill machine introduces the fresh or recycled antifreeze/coolant into the cooling system of an automobile while simultaneously draining the used antifreeze/coolant into the used coolant reservoir. When the engine is cold, the engine's inlet side-thermostat will prevent new antifreeze/coolant from entering the cooling system, thereby making it possible to drain the used antifreeze/coolant from the cooling system, without simultaneously replenishing the cooling system with fresh or recycled antifreeze/coolant. The present drain-and-fill machine includes a thermostat disposed in the reservoir drain line having similar operating characteristics to the engine's inlet-side thermostat. The drain line thermostat will thus prevent the used antifreeze/coolant from being drained from the engine's cooling system when the engine's inlet-side thermostat is closed, until the coolant has reached a sufficient temperature to allow both the inlet-side and drain-line thermostats to open.

Title: Process and device for determining the characteristics of a motor vehicle's built-in shock absorbers
Inventor: LANGLECHNER RICHARD
IPC: G01M17/04
Filed: 1995-08-17
Abstract: A process is proposed for determining the characteristics of a motor vehicle's built-in shock absorbers. The vehicle is driven onto a ramp support which is then quickly removed, causing the vehicle to drop onto a base whose distance below the ramp support corresponds to the residual rebound clearance associated with the particular vehicle design; the changes in the so-called wheel contact force when the car hits the base are measured. The process is characterized by the fact that the vibration characteristics of the body and one wheel at a time ate measured, the measurement results, together with the measured values of wheel contact force, are fed into the known differential equations governing damped oscillations, and the characteristic data for the vehicle structure, namely, the body- and heel masses, spring stiffness and damping constants, are calculated.
