Abstract: A chair apparatus for supporting a back of a person. The chair apparatus has a backrest and at least one support member attached with respect to the backrest. Each support member extends away from the backrest and forms an implantable element which can be inserted into and beneath a ground surface, such as into sand or dirt.

Abstract: A process for forming peelable seals between a layer of spunbonded olefin material and an unsupported film of polyethylene or to a supported film of a laminated or coated backing, such as polyethylene coated Mylar, to form a peel-seal packet, container or pouch. The spunbonded olefin material is first pretreated with a heated die in the areas that are to form the peel-seal with heat and pressure suitable to render uniform surface characteristics to the spunbonded olefin. The heat, pressure and dwell time of the pretreatment are sufficient to eliminate the high spots and internal weaknesses of the spun-bonded olefin material following which a web of synthetic polymeric material having a heat sealable surface may be peelably sealed by a conventional heat sealing method.

Abstract: An inflatable kite exhibiting excellent lift and stability characteristics without an auxiliary tail and comprising an inflatable body member provided with a rounded leading edge and having a substantially teardrop shape, two inflatable opposing rearwardly projecting side members attached to said body member and together forming a single inflated volume, a web of flexible sheet material connected between each side member and said body member and extending over at least about 50% of the area defined by said body member, the side member and a straight line joining the rear extremities of said body member and said side member, and a line attachment member bonded to said body member; the ratio of the maximum width to the length of the inflated kite being about 0.5 to 1.5.

Abstract: An inflatable kite exhibiting excellent lift and stability characteristics without an auxiliary tail, even in small size kites from about 12 to about 18 inches long. The kite of this invention comprises an inflatable body member provided with a rounded leading edge and having a substantially teardrop shape, two inflatable opposing rearwardly projecting side members attached to said body member and together forming a single inflated volume, a web of flexible sheet material connected between each side member and said body member and extending over at least about 50 percent of the area defined by said body member, the side member and a straight line joining the rear extremities of said body member and said side member, and a line attachment means bonded to said body member, the ratio of the maximum width to the length of the inflated kite being about 0.5 to 1.
