Patent CA-2142116-A1 (CA)
Title: Agricultural machine
Inventor: WILLIAMS MERVYN W
IPC: A01F29/10
Filed: 1993-08-09
Abstract: The specification discloses an agricultural machine (2) for cutting long stemmed animal feed material such as hay and comprises a cylindrical cutting drum (4) mounted for rotation about a substantially horizontal axis (6). A plurality of cutting blades (8) project radially outwards from the circumferential surface (10) of the drum (4). The machine (2) also includes a moveable bed (14) on which, in use, lies the material to be cut. The bed (14) can turn about a horizontal pivot axis (16) adjacent the drum (4).  Hydraulic cylinders (18) connected between a frame (20) of a support for the machine (2) and the bed (14) are provided to turn and hold the bed (14) at different angles about the pivot axis (16). The bed (14) includes first, second and third adjacent flat sections (22, 24 and 26) arranged in a U-like configuration. The hydraulic cylinders (18) are used to control the elevation of the bed (14) and therefore the rate of feeding of the material to be cut to the cutter drum (4). A shutter arrangement (42) is located beneath the drum cutter (4) to control the length of time that the material is in contact with the cutting blades.

Title: Method for the storage of entomopathogenic nematodes
Inventor: BEDDING ROBIN A
IPC: A01N63/00
Filed: 1993-09-10
Abstract: Long-term storage of infective third stage juveniles of nematodes belonging to the genera Steinernema or Heterorhabditis is effected by mixing together an aqueous cream of the nematodes and particles of a highly water-absorptive material. The water present in the mixture is such that the mixture, after equilibrating, has a water activity in the range of from 0.80 to 0.995 (prefer-ably 0.95 to 0.99). The preferred absorbent material is anhydrous polyacrylamide gel in the form of particles having an average mass of 0.01 gm. For optimal survival of the nematodes, the equilibrated mixture should be stored at a temperature in the range of from 1 °C to 30 °C, in an atmosphere which maintains the water activity of the mixture in the range of from 0.80 to 0.995.
Patent CA-2148510-A1 (CA)
Title: Brushless permanent magnet condenser motor for refrigeration
Inventor: BAKER GERALD N
IPC: H02K5/22
Filed: 1995-05-03
Abstract: A motor, described as a brushless permanent magnet (BPM) motor, has a cup-shaped, open bottomed enclosure having a side wall and a top wall defining a lower interior space.  The side wall has a port interrupting a bottom edge.  A printed circuit board or other motor electric circuit is positioned above the top wall, below the stator.  Electrical conductors electrically connected to the electric motor circuit extend through the top wall and into the interior space.  Current supply conductors extend through the side wall port and are electrically connected to the electrical conductors from the circuit.  An enclosure cover member has, projecting into the interior space, at least one deflectable prong with an overhanging lip, and a strain relief block positioned adjacent but spaced from the side wall port.  The cover has a tool-receiving aperture to permit engagement of a tool with the prong.  A ledge, carried by an inner surface of the enclosure, is positioned complementarily to the prong lip to permit the lip to engage a surface of the ledge remote from an inner surface of the cover to hold the cover in position, but to permit the displacement of the prong by a tool inserted through the cover aperture to release the prong and the cover.  In the illustrative embodiment, conductor wires from a circuit board mounted above the top wall are mounted in a connector block within the enclosure, and the lip-engaging ledge is part of the connector block.  The enclosure and the cover preferably are constructed from electrically insulative material.

Title: Spring-Biased Latch
Inventor: GAURON JACQUES P
IPC: F16B2/06
Filed: 1995-11-10
Abstract: A spring-biased latch is disclosed for removably attaching a first component, such as a seat, to an elongate member, such as the tubular frame of a wheelchair.  The spring-biased latch comprises a body portion having a top and a pair of leg members that are adapted to removably receive an elongate member, a catch arm pivotally attached to the top of the body portion, and a release lever pivotally attached to the top of the body portion.  The catch arm and release lever are configurable in a first position where the inboard end of the release lever abuts the inboard end of the catch arm such that the catch arm braces a portion of the wheelchair seat between the outboard end of the catch arm and the tubular frame of the wheelchair.  The catch arm and release lever are also configurable in a second position where application of force to the outboard end of the release lever pivots the inboard end of the release lever away from the inboard end of the catch arm such that the catch arm pivots away from the wheelchair seat so that the catch arm does not brace a portion of the wheelchair seat between the outboard end of the catch arm and the tubular frame of the wheelchair.  To re-secure the wheelchair seat to the tubular frame of the wheelchair, application of force to the outboard end of the catch arm pivots the catch arm and release lever so that the inboard end of the release lever abuts the inboard end of the catch arm and the outboard end of the catch arm braces a portion of the wheelchair seat against the tubular frame of the wheelchair.
Patent CA-2164311-A1 (CA)
Title: Tufted articles and related processes
Inventor: HAMILTON WAYNE M
IPC: D05C15/34
Filed: 1994-05-25
Abstract: Processes for tufting substrate or primary carpet backing (111) using conventional double needle bars (116, 112) but in which the needles may be shifted less than a full gauge. Processes of the present invention may employ a conventional double needle bar tufting machine (133) to which is added means for shifting or indexing the hook bar (134) laterally to the machine direction of the substrate being tufted. Timing of shifting of the hook bar (134) may be coordinated with timing of shifting of the needle bar (133) and advance of the substrate (111) through the machine to allow piles (132) to be tufted into the substrate (111) at any desired lateral position with respect to previously tufted piles. The invention creates additional pile color pattern alternatives and eliminates repetitive patterns otherwise necessitated by full gauge shifting. Elimination of repeat color sequences reduces matching color sequences on adjoining edges of adjacent carpet tiles made from such substrate which otherwise accentuate or highlight the seams between carpet tiles.
Patent CA-2165869-A1 (CA)
Inventor: MIRIGIAN GREGORY E
IPC: A61F2/00
Filed: 1995-12-21
Abstract: A thermally activated occlusive implant delivery assembly is provided.  The assembly includes an occlusive implant device and a pusher.  The pusher has a distal section and a proximal section.  The distal section includes a coupling portion which is shape memory material and exhibits different configurations depending on the coupling portion's temperature.  The coupling portion interlockingly engages the implant when it is in one of the configurations and releases the implant from interlocking engagement therewith when in another one of the configurations.  In operation, the assembly is introduced into the body of a mammal via a guide catheter suited for the particular lumen being navigated.  When the implant is positioned at the desired site, the coupling portion of the pusher is thermally activated to effect the return of its original, pre-set configuration, which is originally formed to release the implant from interlocking engagement therewith.  The pusher can then be readily removed from the mammal without imparting any significant force on the implant during retraction.
