Patent CA-2256677-A1 (CA)
Inventor: D ACCHIOLI VINCENZO
IPC: D04H1/54
Filed: 1997-05-28
Abstract: The present invention relates to the selection of materials which are particularly useful as fluid distribution material for being used in disposable absorbent articles by being characterised in that they have a wicking time of less than 120 seconds and a cumulative flux of more than 0.075 grams/cm2/ second for said preferential fluid distribution direction at 12.4 cm height, when applying the Vertical Wicking Test. A further useful selection criterion for such materials is a non-isotropic fluid distribution behaviour, expressed in that the wicking time in the preferential distribution direction is less than 80 % of the wicking time of perpendicular direction at 8.3 cm height, when applying the same test.

The invention can be potentially applied to other systems comprising a swellable hydrogel and a nonswellable hydrophobic polymer.
Patent CA-2263866-A1 (CA)
Title: Beam-type axle suspension system
Inventor: RAMSEY JOHN EDWARD
IPC: F16F1/387
Filed: 1997-08-27
Abstract: An air-ride beam-type axle suspension system for tractor-trailers and other heavy-duty wheeled vehicles having a brake chamber of an air brake assembly mounted on the beam, wherein the beam is tapered. Specifically, each beam of the axle suspension system tapers from a narrower width at its end that is pivotally attached to a frame rail of the trailer, to a wider width at its opposite end. The wider width of the beam enables a slack adjuster of the brake assembly to be disposed within the confines of the beam and still be accessible for repair, removal and/or replacement, without requiring an access cutout in the beam which could potentially weaken the beam structure. The tapered beam also provides, at its wider portions, efficient support for the axle and air springs of the suspension system, easier mounting of the suspension system on existing trailer frame rails and incorporation of a reduced-size pivot bushing at the narrower end of the beam, and optimizes the weight of the axle suspension system.

Patent CA-2269317-A1 (CA)
Inventor: COLE RUSSELL L
IPC: B29C44/36
Filed: 1999-04-16
Abstract: A method of filling an elongated generally lineal channel with polymeric resin foam, preferably polyurethane foam, using an application gun having a laser sight for accurately aligning the application gun relative to the longitudinal axis of the channel to be filled. The method of this invention includes locating the application gun nozzle opposite the open end of the elongated generally lineal channel to be filled, directing and aligning the laser beam along an axis generally parallel to the longitudinal axis of the lineal channel to a predetermined point exterior of the channel spaced from the open end of the channel, thereby aligning the application gun nozzle generally coincident with the longitudinal axis of the channel, using the application gun to direct a thin elongated stream of liquid foamable polymeric resin into the channel open end along an axis generally coincident with the longitudinal axis of the channel, and allowing the liquid polymeric foam resin to foam and rise through the channel, substantially filling the channel with polymeric foam.  In the preferred embodiment, the laser is fixed to the laser gun by a bracket which aligns the laser beam at a small acute angle to the axis of the nozzle of the application gun and the laser beam is then sighted to a point at or adjacent the opposed end of the channel accurately aligning the application gun with the channel to be filled in mass production applications.

Filed: 1999-10-04
Abstract: A boar cart (10) for carrying a boar through alleyways of a sow insemination area for interaction with the sows during insemination is formed by a cage for containing the boar including a cage floor (17) on which the boar stands, two sides (50, 51) each defined by vertical bars on a respective side of a longitudinal center line of the cage assembly for confining the boar so that the boar is maintained extending longitudinally of the cage, a front (52) and a rear (53) defined by vertical bars, at least one of which can be opened as a door to allow entry and exit. The cage is mounted on rear driving wheels (22) and front steering/caster wheels (35, 36). The cage is defined by a front portion (12) and a rear portion (11) connected together for pivotal articulated movement about one or two pivot couplings defining a vertical pivot axis (13) arranged substantially at the center line such that the cage can articulate to the left and to the right for navigating left and right corners in the alleyways while the boar is retained in the cage. The length of the cage is reduced by bowing the front and rear bars. The front steering wheels (35, 36) can be set to direct the steering slightly to the left or right so as to tend to guide the cage along one or other side of the alley where it has rollers (43, 44) to run along a rail and hold the boar close to the sows on one side.
