Abstract: A water walker which is attachable to a user's foot and which, when used in pairs, i.e., one walker for each of a user's feet, allows the user to move across the surface of a body of water while standing upright, includes a buoyant flotation member, a pair of spaced apart runners longitudinally extending along the bottom of the buoyant member, and at least one water control mechanism in the space between the runners. Each control mechanism includes opposed baffles which extend towards one another a distance less than one half the spacing between the runners, and a pivotable gate which is positioned to allow water to pass between the baffles when the walker is moved forward, but which is biased so as to be repositioned to prevent water from passing between the baffles once the walker has completed its forward movement. Each buoyant flotation member includes an overhang portion on the side thereof opposite the adjacent member to enhance the stability of the walker.

Abstract: This invention discloses an improved inflatable swimming ring. Two semicircular and light-weight, hard members are adhesively welded on an outer face of a conventional swimming ring band, the ends of which members are adapted automatically to be connected with each other by the tensile force on the internal pressure of the swimming ring when it is inflated. Conversely, the two members are spontaneously separated as air within the swimming ring band is exhausted, making it easier to store the band. With this invention it is possible to prohibit the distortion and the deformation of a conventional swimming ring, to stabilize the ring and to facilitate its multipurpose usage.

Abstract: A slide fastener is provided with flanges projecting forwardly of the front or diverging end portion of a slider body to form a V-shape. The flanges define a pair of diagonal guide faces for guiding foreign matter inwardly toward the central bridge portion of the slider body. Fastener element-receiving openings are formed by the edges of the flanges which also form the guide faces. If foreign matter, such as waste thread, is lodged between teeth of the fastener elements, it is guided along the slider guide faces from the outer edge of the slider to the central bridge thus removing the foreign matter. As a result, jamming of the slider is prevented.

Abstract: The invention relates to a pneumatically powered tool for expanding elastic rings. The expander includes four prongs which in use are passed through a ring and forced apart by a pneumatic ram to stretch the ring into a square by a reverse cam action of a pneumatic ram thereby opening two jaws which each carry one prong. The second pair of prongs are carried by two arms each linked to a jaw so as to open and close with the jaws. The arms are also directly coupled to the ram so that when it acts to open the jaws it also slides the arms longitudinally along the jaws so that the arm prongs are forced longitudinally apart from the corresponding jaw prongs.When a double acting pneumatic ram is used a tool mounted two-section two-way rocker valve directs compressed air to the appropriate side of the ram piston and allows air to be exhausted from the opposite side.

Abstract: The invention is concerned with the reduction of the vibration transmitted from a mechanism having at least one element rotating at a fundamental frequency and one or more cyclically displaceable further elements connected to said rotating element, and in which the displacements of said further elements produce an aggregate cyclic linear exciting force of fundamental frequency and harmonics thereof acting on the same line. To prevent transmission of vibrations produced by said exciting force from the mechanism to its support means, the mechanism is constrained to prevent all degrees of freedom of movement relative to the support means except for movement under the influence of said linear exciting force which is thereby isolated from the support means. The mechanism also has balancing means integral with or attached to said rotating element for balancing any rotating force produced at said fundamental frequency.
