Patent CA-2381019-A1 (CA)
Title: Hay conditioning apparatus
Inventor: MACKIE PETER GILBERT
IPC: A01D82/02
Filed: 2000-09-15
Abstract: A hay conditioning apparatus (20) includes a first roller (22) which is rotatably mounted in a fixed mounting and a second counter-rotating (compression) roller (24) which is rotatably mounted in connection with a moveable mounting (26). The compression roller (24) is in rolling contact with the first roller (22) and is adapted to receive pre-cut hay therebetween for conditioning. The moveable mounting (26) allows the second roller (24) to be displaced relative to the first roller (22) as the hay passes between the rollers (22, 24) and also includes a hydraulic cylinder (32) for applying a compression force to the compression roller (24). As the pre-cut hay passes between the rollers (22, 24), it is subjected to a predetermined compression force sufficient to substantially flatten any green nodes on the hay and thereby accelerate drying of the hay.

Abstract: A drawer interlock system for a multi-drawer filing cabinet includes respective cam units, one associated with each drawer. The cam units are aligned on a common axis and each unit includes an in-line cam assembly that includes a rotary cam and two stationary cams, one above and one below the rotary cam. When a drawer is opened, the rotary cam is turned, causing axial displacement of the stationary cams, which takes up available "play" in the system, locking the cam units of the other drawers and preventing them being opened.

Abstract: An accurate, portable skate blade gauge comprises an extruded body having a blade-receiving recess, a clamping screw for pressing the blade against a side wall of the recess, and a pivoted indicator arm having a base near the pivot for engagement with the blade edge, and a pointer remote from the pivot for indicating squareness of the blade. The pivot is a resilient pin of spring metal disposed in a hole in the gauge body and fixed to the bottom of the hole. A clearance between the pin and the wall of the hole allows the pin to flex when the skate blade is pressed against the base of the indicator. The resilience of the pin ensures that the blade remains in firm contact with the base of the indicator arm to achieve precise and accurate measurements.

Title: A process for generating electricity with a hydrogen fuel cell
Inventor: DUTIL FREDERIC
IPC: H01M8/0668
Filed: 2002-07-10
Abstract: The object of the invention is the coupling of a hydrogen fuel cell to an enzymatic process for the production of electricity and the transformation and sequestration of CO2. Gaseous CO2 emissions from processes such as hydrocarbon reforming are transformed into carbonate or bicarbonate ions and hydrogen ions by the enzymatic system in order to prevent their contribution to the greenhouse effect.      The hydrogen ions resulting from the enzymatic process are recovered and combined in order to supply the hydrogen fuel cell. Finally, water, a by-product of the oxidizing reaction of the hydrogen fuel cell, is recovered and recycled back into the aqueous enzymatic system.

Title: Valve pin cross over nozzle
Inventor: RICK ROBERT
IPC: B29C45/32
Filed: 2002-10-09
Abstract: According to the present invention, a cross over nozzle is provided of two parts which, when joined, define a housing having a passage extending therethrough, a tapered valve seat extending about the passage and a valve member having a tapered valve head disposed in the passage for engaging the valve seat. The two parts are axially separable at an interface extending through the valve seat/valve head. In order to open the valve, both valve parts are first joined and then moved together as one member in the same direction relative to the housing axially away from the valve seat. Similarly, the valve members are jointly moved into engagement with the valve seat before the cross over nozzle is separated. Accordingly, unlike the valve gate design, the valve interface between the two parts of the valve head isn't exposed to molten resin and therefore molten resin isn't trapped therebetween to cause a string upon opening.
