Abstract: An adjustable leveling system for leveling foundations subject to subsidence and frost heave and is particularly suited for use in permafrost and cold regions as characterized by an adjustable leveling system comprising a base for supporting a hydraulic leveling jack wherein the leveling jack has a hollow support tube mounted thereon and the support tube extends upwardly from the hydraulic jack.

Abstract: An anti-jacking pile solution particularly suited for use in permafrost or cold regions. The pile includes bond breaking material for preventing frozen soil from directly gripping a pile near the surface of the soil and pulling the pile upward. A collar is attached to the pile to prevent damage and/or displacement of the bond breaking material during driving of the pile. The pile may be attached to a building by way of an adjustable connection system allowing for future adjustments in the event of vertical movement.

Abstract: There is disclosed an athletic shoe that finds most efficacy with joggers. The shoe is supplied with a conventional upper and sole. The usual lacing arrangement is provided with the exception that additional lacing means is provided along both sides of the shoe whereby the counter containing heel portion of the shoe is constrained in a manner so that the heel portion of the athletic shoe is brought inward in the direction of the centerline of the shoe to effectively lock the heel portion with the front portion. The tying arrangement may be a continuation of the usual lacings or may be two separate laces, but in any event essentially locks the front and back of the shoe together. The lace arrangement extending to the counter or heel portion is positioned whereby the means is substantially parallel to a "spring" ligament as normally located in the foot.

Abstract: There is disclosed a cushion pad for sport shoes and the like and a method for manufacturing such a pad and the combination of such a pad with a sport shoe and the like. The pad of the present invention is fabricated from a flat web of closed pore foam of cross-linked ethylene vinyl acetate-low density polyethylene copolymer. The pad is formed between two opposing molds to present a shape having a cup-like depression adapted and constructed to accept essentially the heel portion of a human being. The so-formed pad is then cut out of the remainder of the formed web in a manner whereby the pad provides support from just in back of the first metatarsal joint to the sides and back of the calcaneus. It has been found that the resultant pad made within the purivew of the invention requires only a few sizes to fit most of the feet of possible users.

Abstract: An improved cold neutron radiographic apparatus and method are disclosed wherein neutron temperature is matched to the specific material to be examined. This can be done, in one embodiment, by placing a radioactive source of neutrons, such as californium 252, in a moderator such as solid methane and using a cryogenic refrigeration system to cool the moderator to any pre-selected cryogenic temperature.
