Abstract: PCT No. PCT/EP95/04438 Sec. 371 Date Apr. 20, 1998 Sec. 102(e) Date Apr. 20, 1998 PCT Filed Nov. 10, 1995 PCT Pub. No. WO96/15378 PCT Pub. Date May 23, 1996A self-drilling and thread-forming screw comprises a threaded shank, a drilling section arranged in front of the shank and having a uniform diameter, and a thread-free flow-forming section widening conically between the drilling section and the shank. The drilling section has two chip grooves which run diametrically opposite one another, are bounded by flute edges and cutting edges, and end in a drilling tip with the cutting edges running together at the tip. The diameter formed by the cutting edges is smaller than a minor diameter of the threaded shank, and the largest diameter of the flow-forming section corresponds to the minor diameter of the shank and includes a symmetrical polygonal cross-section with rounded-off corners in a region adjoining the shank. The chip grooves also extend from the cutting edges over a substantial part of the flow-forming section, the flute edges run in the direction of the shank tangentially into the rounded-off corners, a transition region is provided between the drilling and flow-forming sections, and bead-shaped prominences are formed on the drilling section remote from the chip grooves. The prominences form an increasing cross-sectional extent as they merge continuously in the transition region into the rounded-off corners diametrically opposite one another, such that this extent is equal to the diameter formed by the cutting edges in the transition region and is greater than the diameter formed by the cutting edges in the flow-forming section.

Title: Buckle with a pawl, particularly for a snowboard
Inventor: DODGE DAVID
IPC: A43C11/14
Filed: 1995-01-25
Abstract: A snowboard ratchet-type buckling arrangement (12) includes a housing (18) and a strap (20) slidably received within the housing (18). The strap (20) has a rack of teeth (22) on its upper surface. A tab (32) is pivotally mounted to the housing (18) about a first axis (26) and is spring-biased (36) into engagement with the rack of teeth (22) on the strap (20). The tab (32) allows the strap (20) to move in a first direction and prevents movement of the strap (20) in a second direction. A lever arm (24) is pivotally mounted about the housing (18) about the first axis (26) and a second axis (30) which is spaced from the first axis (26). When the lever arm (24) is pivoted about the second axis (30), saw teeth (38) engage the rack of teeth (22) on the strap (20) to incrementally ratchet the strap (20) through the housing (18) in the first direction.

Title: Aqueous agent
Inventor: XIAOHONG CI
IPC: C08F20/00
Filed: 1993-10-19
Abstract: An aqueous composition is described. The composition comprises a film-forming latex polymer having anionic character; a water-soluble or water-dispersible polymer formed from at least about 20% by weight monomer containing amine functional groups; and a volatile base in an amount effective to raise the pH of the composition to a point high enough where essentially all of the amine functional groups are in a nonionic state; and optionally a water-soluble or water-dispersible multivalent metal. The composition provides an aqueous, quick-set noncementitious composition which is easily applied, develops early cohesive strength and leaves no waste under all curing conditions. The invention is particularly useful as an adhesive used in exterior insulating and finishing systems. The composition also provides an aqueous, exterior, quick-set coating composition having early washout resistance and dirt pick-up resistance. The invention is also particularly useful as a binder used in a traffic paint and as a base coat and/or top coat in exterior insulation finishing systems.
