Title: Trough wood grinder
Inventor: GOFORTH GEORGE L
IPC: B27L11/00
Filed: 1992-10-02
Abstract: ABSTRACT OF THE DISCLOSURE A wood grinding device for grinding and pulverizing wooden objects and materials into wood chips.  A trough into which the wooden materials are deposited is provided with a reciprocating action to transfer the contents of the through to a hammer and anvil unit.   The hammer and anvil unit includes a flywheel which is contained within an enclosure beneath the trough.  Rotatably mounted along the perimeter of the  flywheel  is a  plurality  of  hammers.    The  interior perimeter of the enclosure is formed with a plurality of anvils which coact with the hammers to pulverize the contents transferred from the trough.  The reciprocating action of the trough exposes the full length of the trough to the hammer and anvil unit.  In addition, dual lateral openings are provided in the enclosure which, in cooperation with a bi-directional capability of the flywheel, allows an operator to select the direction of rotation of the flywheel on the basis of which lateral opening to use,  or alternatively,  to selectively subject one edge of the hammers to the contents of the trough in order to promote more even wear of the hammers.

Patent CA-2082246-A1 (CA)
Inventor: KALLENBERGER HARVEY
IPC: F16H57/02
Filed: 1992-11-05
Abstract: The invention involves a machine, e.g., a walking dragline having a drive gear, a driven member which loads (and wears) gear teeth unequally and an interconnecting shaft.  The quill-mounted gear is separately supported by bearings.  The shaft can be moved axially and when so re-positioned, it is also separately supported by other bearings.  When the gear needs to be "indexed," (due to unequal tooth wear) the shaft is moved axially out of connection with the gear but remains connected to the eccentric.  The gear can then be indexed using its drive motor and the shaft can be re-engaged with the quill without the necessity of auxiliary lifting equipment and without disengaging the shaft from the eccentric.
Patent CA-2085499-A1 (CA)
IPC: E04D13/15
Filed: 1992-12-16
Abstract: This invention provides a panel assembly for buildings and the like comprising, in combination with structure supporting the assembly, an array of overlapping elongated metal panels, each panel including a lower edge, an upper flange, and a web including at least one outwardly protruding longitudinally extending stiffening rib.  The stiffening rib adjacent the upper flange has an elongated longitudinally extending groove and an extended bearing portion for contacting the structure when the panel is fastened thereto. These ribs provide structural support without purlins, sheathing, or the like.  A plurality of fasteners for attaching the panel assembly to the structure pierce the extended bearing portion and hold the bearing portion in contact with the structure so that when panels are affixed to the structure with the lower edge of one panel overlapping the upper flange of another panel, the groove forms a space between overlapping panels to prevent water from flowing around the stiffening rib adjacent the upper flange.

Patent CA-2088916-A1 (CA)
Title: Pile weatherstrip
Inventor: HALL ALFRED B
IPC: B29C65/08
Filed: 1992-06-12
Abstract: A pile weatherstrip has an elongate base strip (10) carrying a pile of thermoplastic fibres (11). A zone (15) is formed adja-cent the base of fibres fused together and compressed to reduce their width.  This provides a comparatively smooth and narrow zone that does not snag on the flanges of a carrier as the pile weatherstrip is inserted into the carrier. The zone (15) can be pro-duced by passing the weatherstrip through a nip formed by heated rollers (18).  In an alternative embodiment, the fibres are fused together for their whole height. This has the additional advantage of providing an air-impervious barrier.

Filed: 1993-06-21
Abstract: Glass sheets are heated to their heat softening temperature and transferred to a shaping station having an upper vacuum mold with a downwardly facing shaping surface corresponding to the desired shape of the glass sheet. The glass sheet is lifted into engagement with the shaping surface and held thereagainst by vacuum.  The mold and the glass sheet are then moved to a transfer station and the vacuum is released to deposit the shaped glass sheet onto a contoured conveying surface which generally conforms to the shaped glass sheet.  The glass sheet is deposited onto the contoured conveying surface as it is moving from the shaping station to the transfer station to impart movement in the glass sheet along the contoured conveying surface and minimize marring of the glass sheet as it contacts the contoured conveying surface.
