Abstract: Food products having high dietary fiber content and unexpected organoleptic characteristics, the invention takes the form of a substantially solid or semi-solid substrate formed primarily of dietary fiber soaked in or permeated by a flavorful material such as a natural juice, liquefied or pureed fruit or the like, the combination then being at least partially lyophilized to a solid or semi-solid consistency. The concentration of the natural juice or other flavorful material within a framework or lattice provided by the dietary fiber causes a burst of flavor to be experienced when eaten. While the lyophilized substrate can preferably be consumed as a bar-like comestible with or without the addition of other materials such as coatings, fillers and the like, the invention contemplates the formation of the substrate as flakes, as a cookie, as a candy such as a semi-soft roll or sheet consumed flat or as a rolled sheet among other forms. In all forms, the inventive food product provides healthful benefits known to be associated with desirable intakes of dietary fiber and tasteful enjoyment due to taste characteristics not previously present in food products of high fiber levels. The invention further relates to the methodology for preparation of the present food products.

Abstract: The invention takes as its basis the problem of creating a safety sealing device for gas pipes by which the bearing of the valve body should be frictionless, require no maintenance and which causes only minimal flow resistance. Further the safety sealing device should not require outward sealing connections. It should be easy to install and able to be fitted into existing gas piping or fittings without having to change them.    The problem is solved in that with safety sealing devices with a valve body (6) which can be pressed against a valve seat (1), whereby the valve body (6) is supported so that it is movable in the axial direction of the valve seat (1) is against the force of a locking spring (8), the valve body is conducted only through a spring and is otherwise freely movable without additional support points.       The invention concerns a safety sealing device for closing gas conduits in cases of damage, e.g. pipe bursts or hose ruptures, in order to prevent an uncontrolled leakage of gas and thereby a dangerous situation.

Abstract: A method of automatically assembling wiring devices of the type having mounting straps in a continuous sequence, the disclosed wiring device being a duplex wall receptacle. A strip of the mounting strap material is fed longitudinally, being alternately moved by equal increments and stopped to place each segment of the strip progressively at a plurality of operational stations. Portions of the strip are removed to form blanks for the mounting straps which remain mutually attached at positions along each side of the strip which form end portions of the blanks and, ultimately, of the mounting straps. One or more additional strips in which ground contact blanks have been formed are fed in a direction perpendicular to that of the first strip and the ground contact blanks are staked to the mounting strap blanks and severed from their respective strips. Front and rear housing sections, the latter having terminal members positioned therein, are moved from opposite sides of the strip in which the mounting strap blanks are formed into mutual engagement, enclosing a medial portion of the mounting strap. At the endmost station, the strip is severed to provide a fully assembled wiring device.
