Abstract: A rotary mixer and disperser head consisting of a shaft to which is connected a mixing chamber that is to be disposed into a vat or the like for dispersing, dissolving or blending of solids liquids or gasses with other liquids. The mixing chamber has secured to its upper and lower ends a plurality of impeller blades that have an end thereof located outside the mixing chamber to direct material into the mixing chamber and out through openings in the side wall of the mixing chamber during the mixing and dispersing thereof. The shaft for rotating the mixing chamber is merely located at one end thereof and doesn't extend into the mixing chamber and thus does not impede the mixing action taking place therewithin. The specific location of the blades, their relationship relative to the mixing chamber and their configuration provide for a very efficient mixing operation.

Abstract: A combinatorial data entry system useful with a computing apparatus comprises two multi-position switches. A data entry system useful with a telephone comprises one multi-position switch. Each multi-position switch includes a control knob, which can be manually tilted between a rest position and any of twelve tilted positions and is biased to the rest position, and twelve switchable devices, which may be electrical, opto-electronic, capacitive, or magnetically activated. Electrical switching devices having stationary and movable contacts are preferred. In each multi-position switch, each switchable device has a deactivated state and an activated state and corresponds uniquely to one of the tilted positions of the control knob. Each switchable device has an active output when switched from the deactivated state into the activated state.

Abstract: A predominantly paperboard pallet comprises longitudinally extending outer stringers, made from an intermediate article folded from a corrugated paperboard sheet so as to have a lower panel and six panels on each side of a vertical plane bisecting the lower panel. On each side thereof, an outer panel extends upwardly and outwardly from the lower panel, an outer panel extends inwardly from the upwardly and outwardly extending panel, to the bisecting plane, an inner panel extends downwardly from the inwardly extending panel, approximately to the lower panel, an inner panel overlies the lower panel and extends outwardly from the downwardly extending panel, to the upwardly and outwardly extending panel, an inner panel extends upwardly and inwardly, to the downwardly extending panel, and an inner panel underlies the inwardly extending panel and extends outwardly, to the upwardly and outwardly extending panel. The underlying panel is secured adhesively to the inwardly extending panel.

Abstract: A transanal inserter is disclosed which facilitates the atraumatic insertion of intra-anal surgical devices through the anus. The inserter has a tubular portion, a prolate distal end and a proximal end having a flange associated therewith. The prolate end is formed from a plurality of petal-shaped segments which deflect outward as an intra-anal surgical device is urged therethrough, into the colon or intestine. The flange formed at the proximal end of the inserter retains the inserter in place and prevents over insertion of the inserter beyond the anus. The inserter can be fabricated in varying lengths to accommodate surgical requirements. The inserter is fabricated from a plastic material with sufficient pliability to provide for deflection of the segments, while maintaining sufficient rigidity to prevent collapse of the inserter during insertion and use.

Abstract: A resilient clip or spring clip is disclosed which has a pair of jaw members and a generally U-shaped biasing member for connecting the jaws together and for biasing the jaws into a closed position. The biasing member has a pair of legs connected by a curvilinear central portion and a curvilinear support portion interior thereof. The central portion and support portion are connected by a bridge-like member, and define a channel therebetween. The sidewall of each jaw member has a closed sidewall extending along a substantial portion thereof and defines an arcuate surface. During actuation of the clip, the sidewall traverses through the channel in the biasing member, while the support portion defines and serves as a fulcrum for rotation of the jaws between the open and the closed positions, independently of any separate support member.

Abstract: A disposable absorbent garment, illustrated as a disposable diaper, includes a backsheet, an absorbent panel positioned on top of the backsheet, and a composite, three-component topsheet assembly positioned on top of the absorbent panel. The topsheet assembly includes a central portion generally overlying the absorbent panel, and a pair of side marginal portions joined to opposite side edges of the central portion. Each side marginal portion includes a plurality of segments, including an elasticized, standing gather segment for enhanced containment. The containment characteristics of the garment are further enhanced by joining the central portion of the topsheet assembly to each side marginal portion in spaced relationship to the associated backsheet of the garment.

Abstract: The invention provides a method for removing metal oxides and colloidal material from high-resistivity water streams at a relatively high removal efficiency. The method includes hydrating a highly ionized dual morphology ion exchange resin in a macroreticular, desiccated morphology to produce a macroreticular, hydrated morphology. A water stream which is brought into contact with the resin is purified. The water stream may, optionally, also be contacted with both a cation exchange resin and an anion exchange resin.The invention additionally provides a method for selecting ion exchange resins which are particularly suited for use in removing metal oxides from a condensate stream. The method serves to narrow the field of candidates for pilot-scale resin testing with industrial water streams.
