Abstract: A snowshoe crampon system has toe and heel crampons which are fabricated from strong, hard abrasion resistant material such as stainless steel, titanium, or tool steel, the toe crampon having a depending formed skirt and a trio of tooth pairs depending angularly therefrom, namely: a pair of forward climbing teeth, a pair of lateral traction teeth and a pair of rear braking teeth, each tooth of each pair having an outwardly curved, convex, crowned outer face which Is grooved to form a gusset, each tooth pair being disposed at such an angle as to contribute to the traction provided by the other two pair; the heel crampon having two pair of teeth, namely: a pair of lateral traction teeth and a pair of rear braking teeth, the pair of lateral traction teeth being disposed on a plane parallel to the direction of snowshoe travel and the pair of rear braking teeth being disposed at an angle relative to the direction of snowshoe travel.
Abstract: A transparent shield is provided for a blackjack or other card table for use by a dealer and players for playing a card game, the shield having a closed front face and an open rear face for providing a space above the table accessible by the dealer for dealing the cards but denying access to the players, thereby preventing marking of the playing cards.
Abstract: A trampoline which incorporates a flexible mat supported above a support frame by a number of spaced flexible rods; each rod is secured at one end to the mat and at the other end to the support frame.
Abstract: Ornamental supports for supporting various items such as shelves, hanging plants, curtain rods, decorative fixtures, flag poles, name plaques, or the like and so constructed that ornamentation associated therewith may be easily be removed and replaced with other ornamentation thereby permitting the substitution of different ornamentation appropriate for differing tastes, different holidays, and different seasons of the year.

Abstract: A tramper's pack includes a sac 3, a shoulder harness 6/7, a supporting frame 4 and a hip belt; the frame 4 is secured to the rear surface of the sac 3 between the top of the sac 3 and a position approximately level with the wearer's lumbar dorsal pivot, but is free to flex relative to the sac below that point; the lower end of the frame 4 is load bearingly connected to the hip belt 9; a load spreading member 20 which incorporates a pair of wing portions 20 a is arranged to spread load from the area of the lumbar dorsal pivot outwards downwards to contact points on the hip belt 9, to which the wings are connected by flexible connection means.
Abstract: A unitary clothespin or multipurpose clamp molded from a resilient plastic material having a hair-pin like configuration comprising a loop for permitting suspension, the loop terminating in a pair of confronting gripping jaws, the jaws being releasably, and pivotally interconnected and being movable between a closed, gripping position in contact with each other and an open, nongripping position not in contact with each other upon the application or. release of a squeezing compressive force upon the loop.
Abstract: A substantially rigid or semi-rigid chair suitable for white-water use with a hydrodynamically efficient underwater profile, capable of efficient human propulsion, using hands and/or legs, which supports the user in a semi-reclining position and which is sufficiently maneuvrable, in both forward and reverse direction, to enable the user to engage in white-water river use. In one embodiment, the chair consisting of two floats (2, 3), rigid/semi-rigid seat base (4), bow hull floor section (12) an adjustable seat back (8) and a waterproof covering (7). The floats (2, 3) are separated by a rigid/semi-rigid central section (15) comprised of the seat base (4), bow hull floor section (12) which extends from the bow (6) for a majority of the chair's length, and together with the seat back (8) providing a semi-reclining body position enabling the user to use hands and/or legs for propulsion/maneuvring.
Abstract: A segmented seal ring and spring system for very low pressure drop zones in steam turbines for minimizing leakage between rotating and stationary components, and preventing damage and wear thereto, including a segmented seal ring, with first springs biased against the seal segments to urge the segments radially inwardly toward a small clearance position of the seal ring with respect to the turbine shaft secondary springs to counter the weight of the segments; with the combination of said springs gently urging the seal segments into the small clearance position while allowing clearance enlargement with small resulting forces on the shaft during periods of misalignment and rubbing.

Abstract: A snowshoe has an integral deck and frame molded from a high impact, plastic material, the frame having integral molded hubs for accepting a unique binding pivot system which includes a molded two piece axle with integral bearings journalled in the molded hubs of the frame, the axle being located in close proximity to the operating plane between the snowshoe and the snow, a non-slip, easy-to-adjust binding, and a steel crampon having teeth with rounded edges which diminishes the risk of children being cut by sharp, pointed teeth.
Abstract: An inflatable chair suitable for white-water use consisting of two inflatable floats (2, 3), rigid/semi-rigid seat base (4), bow hull floor section (12) an adjustable seat back (8) and a waterproof covering (7). The two inflatable floats (2, 3) are circular in cross section and taper at both ends to conical points (10, 11) at the stern and (13, 14) at the bow (6). The floats (2, 3) are separated by a rigid/semi-rigid central section (15) comprised of the seat base (4), bow hull floor section (12) which extends from the bow (6) for a majority of the chair's length, and together with the seat back (8) providing a semi-reclining body position enabling the user to use hands and/or legs for propulsion/manoeuvring.
Abstract: A method for preventing or precluding migration of termites or insects through a possible area of migration for example between a concrete slab (13) and a brick wall (28) erected on the slab (13) including the step of applying to a possible area of migration as for example a join line (15) between the slab (13) and wall (28), a settable or curable barrier material which defines a barrier to termite or insect migration through said area. The barrier material may define a physical barrier or may incorporate a chemical to define a chemical barrier. The method may be used also for preventing termite penetration along pipes (19) penetrating a slab (13) by providing beads (68) around the pipe (19) within the slab (13) or at the junction between the pipe (19) and slab (13).

Abstract: The bar of a chain saw is attached to a jig which includes a support block pivotally attached to a pair of spaced support arms extending outwardly therefrom for supporting a log or branch to be cut, and fingers extending angularly forwardly and upwardly from the ends of the support arms for scooping up logs and branches from the ground onto the support arms and into contact with a pair of spaced upright, toothed stop arms on the support arms which prevent kickback or twisting of the log or branch as it is being cut by the chain saw as the support block is pivoted relative to the support arms between non-use and use positions.
Abstract: A dual purpose rule guard for two-piece rotary cutting dies consists of a pair of confrontable allochiral guards. Each defines on its confronting surface a first portion thereof recessed inwardly therefrom and a second portion thereof projecting outwardly therefrom. The guards of the pair are interdigitable for assuming an interlocked position with respect to each other to insure the correct alignment of the cutting dies and of their rules. Additionally, each guard is so positioned relative to its cutting die that its second outwardly projecting portion projects outwardly of the confrontable edge or join line of the cutting die so that it functions as an overhang to keep the knife at the join line upwardly and away from any storage surface.
