Patent CA-2053098-A1 (CA)
Title: Internal safety valve and pump system
Inventor: ZINK DONALD L
IPC: F04B43/10
Filed: 1991-10-09
Abstract: An internal valve and metered positive displacement pump for a pressure fluid tank. The tank defines a fluid compartment, and first and second vessels are positioned within the protective envelope of the tank. A bellows pump assembly disposed in the first vessel includes a bellows and a piston cylinder arrangement positioned within and attached to the bellows. Pressurized fluid is pumped into and out of the first vessel to actuate the piston cylinder arrangement.      With this actuating movement fluid is pumped from the compartment through a valve in the second vessel and into the second vessel for removal therefrom. The valve is normally closed against the working pressure of the fluid in the compartment by a spring bellows relief assembly in the second vessel. The force of the fluid pump by the piston cylinder arrangement opens the valve, and a check valve pre-vents fluid from flowing back from the valve into the first vessel. A passageway through the first vessel allows the pressurized fluid in the compartment to bear on the bellows and thereby bias the piston cylin-der arrangement to an up (or down) position.

Title: Reinforced thermoplastic components for use in the manufacturing of ophthalmic lenses and methods of making such components
Inventor: ROTENBERG DON H
IPC: B24B13/005
Filed: 1991-10-22
Abstract: ABSTRACT OF THE DISCLOSURE           Components for use in the formation of a finished or partially finished ophthalmic lens, such as lens blocks and prism rings and edging blocks and adapters for example, are formed from a carbon fiber reinforced crystalline thermoplastic containing at least 30% by weight carbon fiber based on the total weight of the component.  The reinforced thermoplastic has a minimum tensile strength of at least about 20,000 psi, a minimum flexural strength of 2 x 104 psi, a minimum flexural modulus of 2 x 106 psi, and a specific gravity of less than 1.60.  The lens block includes a unique arrangement of ribs to strengthen the block and increase its heat transfer properties.  Metal finishing centers are inserted into the block and are  ultrasonically vibrated or heat staked in order to cause the plastic material to flow around and into serrations formed on the finishing centers.

Title: Method of manufacturing a plastic-coated steel mesh sports face mask
Inventor: MARTINITZ FRANZ W
IPC: A42B3/20
Filed: 1991-12-05
Abstract: A wire mesh face mask for hockey or other sports is manufactured from a steel having carbon content in the range of AISI grades C-1018 to C-1038,and preferably C-1022. The mask is made by forming a grid of generally horizontal wires overlaid by generally vertical wires, shaping the grid into a mask shape, welding the wires to each other where they intersect, heat treating and quenching the grid to increase hardness, dipping the grid to coat it with an epoxy coating. This combination of materials and processes permits the use of a thinner wire than has previously been possible in face masks.
Patent CA-2056819-A1 (CA)
Title: Piston assembly with pivot-connecting rod
Inventor: HAMY NORBERT
IPC: F16J1/14
Filed: 1991-12-02
Abstract: ABSTRACT OF THE DISCLOSURE            A piston assembly comprises a piston head adapted for reciprocating movement in a cylinder and a connecting rod for connecting the piston head to a crankshaft. The connecting rod has a big end for pivotal attachment to the crankshaft and a little end for attachment to the piston head.  A coupling unit pivotally attaches the little end to the piston head while ensuring lateral displacement of the pivot point in the same direction as the lateral movement of the connecting rod during rotation of the crankshaft.  In this way the angular displacement of the connecting rod is reduced during the crankshaft cycle and the efficiency of the engine is improved.

Title: Window stays
Inventor: GRIFFIN KENNETH G
IPC: E05C17/24
Filed: 1991-12-12
Abstract: ABSTRACT OF THE DISCLOSURE            A window stay restricts opening of a hinged window leaf by providing an arm connected between the window and a fixed frame.

Patent CA-2061903-A1 (CA)
Title: Compression spring fluid motor
Inventor: WALTON FRANK
IPC: F03C1/007
Filed: 1992-02-26
Abstract: A reciprocating primary fluid driven motor has a stepped piston in a housing having a center hanging actuator rod which extends into the piston to periodically cooperate with an axially shiftable connector member in the piston which operates valves which establish the reciprocating stroke of the piston by opening and closing valve members on the larger and smaller faces of the stepped piston. A block member with compression spring drivers pivotally mounted inside the piston slides on the actuator rod during movement of the piston. The drivers are compressed in response to spaced stops on the actuator rod during continued movement of the piston until a sudden over-center movement of the block member shifts the connector to operate the valve members to cause reciprocation of the piston. Quiet operation during shifting is provided by shock absorbers. No sliding seal with the actuator rod is necessary. Provision for bleeding air from the housing chamber facilitates startup. The stepped piston is connected to a secondary fluid additive pump to inject metered amounts of secondary fluid into the primary fluid stream.
Patent CA-2062985-A1 (CA)
Title: Safety ladder (the)
Inventor: GARSON SHAWN
IPC: E06C1/383
Filed: 1992-03-13
Abstract: ABSTRACT OF THE DISCLOSURE         A new safety ladder is presented which comprises two generally parallel elongated substantially rigid support members, one of which is adapted to be secured to a wall of a building. A plurality of spaced apart rungs are each pivotally secured to each of the rigid support members and the support members and rungs are movable from a storage position (with the rungs generally aligned with the longitudinal axis of the support members) to a use position with said rungs generally perpendicular to the support members. A double release mechanism is provided for securing the ladder in the storage position, latching in two places. One of the support members provides a bias to move the ladder by gravity to the use position, assisted by a spring-loaded mechanism. A stop mechanism is provided, preferably associated with the rungs or with one of the upright support members, for determining the use position, with the rungs generally perpendicular to the support members. The stop mechanism is further assisted by an automatically adjusting moveable leg, which extends to the natural grade of the landscape for maximum stability. This safety ladder is advantageously used in domestic single family dwellings where it can be secured adjacent to a second story window and is releasable at a position on the lop of the ladder generally adjacent to the window such that during a fire the ladder may be moved from the storage position to the use position for evacuation of the second story. Furthermore, the release mechanism is designed to be burglar proof. It is designed to be permanently secured to the exterior wall of the structure and in the storage position looks much like a down spout.

Patent CA-2086256-A1 (CA)
Title: Shape sorting
Inventor: COOK NIGEL R
IPC: B07C5/10
Filed: 1991-06-25
Abstract: In order to provide an accurate sort into may different classes, objects are passed through a viewing zone and viewed at the same instant by a number of viewers. Signals from the viewers are processed to provide signals representative of the maximum, minimum and mean of the blockiness and symmetry of the object, and the maximum and mean of the convex hull deviance of the object. The signals, together with an edge-breakthrough count are subjected to a linear transformation to provide a normalised shape parameter which is then assigned a value of 0 to 15, for each class being sorted, on the basis of the expected occurrence of the value of the parameter in that class. Each pair of secondary shape parameters so determined is used to derive a decision value from the table specific for that pair of secondary shape parameters. The shape class of the object is ascertained on the basis of a majority vote for all the shape decision values. The tables are "learnt" by the machine by feeding a statistically significant number of samples representative of a number of shape classes through the machine.
