Title: Easy off snowmobile trailer
Inventor: ANDOL MARK STEVEN
IPC: B60P3/06
Filed: 1998-02-13
Granted: 2005-06-28
Abstract: A snowmobile trailer comprising a rotatable first frame having a platform comprising two or more side-by-side decks each of which is independently tiltable to the trailer rear so that snowmobiles may be driven forwardly (of the snowmobiles) onto the tilted decks, then the platform rotated 180 degrees for unloading the snowmobiles whereby they may be driven forwardly (of the snowmobiles) off of the decks. The first frame is laterally supported relative to a second non-rotatable frame. A brake dampens tilting movement of a deck. A forward portion of a deck is covered by a shroud. One or more additional shrouds are pivotally attached to be disposed outside the shroud to further cover the deck or to pivotally be telescopingly received within the shroud to allow access to a snowmobile on the deck.

Abstract: PCT No. PCT/FR97/00546 Sec. 371 Date Jan. 22, 1999 Sec. 102(e) Date Jan. 22, 1999 PCT Filed Mar. 27, 1997 PCT Pub. No. WO97/37792 PCT Pub. Date Oct. 16, 1997This mold consists of a cooled mold body (1), made of copper or a copper alloy, on which sits a refractory feed head (2) and a purge slit (8) is made at the interface between said mold body and said feed head, via which a stream of a waste inert gas is injected around the internal perimeter of the mold. The slit is supplied via a plenum chamber (13) made within the mold, the plenum chamber being itself supplied with gas via inlets (12) which connect it to a pressurized-gas supply (20). The injection slit (8) is segmented around the mold perimeter with the aid of separating means (21) which also segment the plenum chamber into compartments (13', 13'', etc.) which are juxtaposed around the perimeter of the mold so that an inlet (12) runs out into each compartment thus formed. Thus, a plurality of elementary circuits (12'- 13''- 8'), which are mounted "in parallel" with respect to a single pressure chamber (20), are produced so that, overall, the injection of gas around the perimeter of the mold becomes insensitive to local perturbations such as local variations in the thickness of the slit.

Abstract: A self-coining fastener (50) which may be used to join at least two sheets of metal (110, 112) together without leaving a coining mark on one side thereof. The present self-coining fastener (50) therefore produces an entirely flush surface on one side of the joined layers (110, 112). The fastener (50) comprises a top surface (52) and a bottom surface (54), the top surface (52) having a larger diameter than the bottom surface (54). A groove (60) is formed around a perimeter of the fastener (50) in order to transition between the two diameter surfaces. Because the top surface (52) of the fastener (50) has a larger diameter, no coining ring is required in the upper die (140) which installs the fasteners (50). The larger diameter head (52) acts as a self-coining manner to push the metal in the joined layers (110, 112) into the central groove (60). The result is an installed fastener (50) in which the larger diameter top surface (52) is entirely flush with the top surface of the joined metals (110, 112), without the presence of a coining mark.

Title: A lamina stack with at least one lamina layer having a plurality of discrete segments and an apparatus and method for manufacturing said stack
Inventor: NEUENSCHWANDER THOMAS R
IPC: B21D28/02

Abstract: A laminated stack (82, 116) having a lamina layer comprised of a plurality of discrete lamina segments (121, 122, 136, 138) and which may also have laminas (118, 120) which define a plurality of outer perimeter configurations.  The invention provides a method and apparatus for manufacturing such stacks (116). Lamina layers (118, 120) comprising a plurality of discrete lamina segments (121, 122, 136, 138) are automatically stacked by positioning the uppermost lamina in a choke barrel (94, 148) near the lower die bed (166) surface and engaging the interlock tabs (144) of the discrete lamina segments (121, 122, 136, 138) with the interlock slots (146) of an uppermost lamina layer in the choke barrel (94, 148) prior to the complete separation of the discrete lamina segments (121, 122, 136, 138) from the remaining portion of the strip stock material (154). Each of the outer perimeter configurations has at least one common choke surface (150). The common choke surfaces (150) form, when the laminas (118, 120, 140, 134) are stacked, a choke contacting surface (150) on the outer perimeter surface of the lamina stack (116) which extends continuously in the axial direction from the top lamina (140) to the bottom lamina (118). A die assembly having selectively actuated punches (90) is used to stamp the laminas (118, 120, 134 140) with a plurality of outer perimeter configurations and the laminas (118, 120, 134, 140) are stacked in a choke barrel (94, 148) with an alignment surface which cooperates with the common choke surface (150) and securely holds the stamped laminas in position while the stack is being formed. Rotation of the choke barel (94, 148) compensates for strip thickness variations.
