A bedspring includes a plurality of spaced parallel longitudinal cross wires and a plurality of spaced parallel transverse cross wires connected to each other at respective cross points and having the ends thereof connected to a frame. The cross wires together form an intersecting grid-like array. Coil springs each have a coil turn at one end thereof which is positioned in a space in the grid-like array of cross wires. Each coil turn is interposed between one pair of transversely extending cross...

An artificial nymph comprising a flat thin frame made of wire or a thin piece of material, relatively broad as compared to its thickness from top to bottom, a hook having a shank extending longitudinally of the frame, and thread material wound on the frame and hook shank forming a flat, thin and broad body simulating a nymph. The shank of the hook may be integral with the frame or may be located above or beneath the frame preparatory to winding and tying of the body material.

Camber is automatically attained in the chords of a truss by means of tensioned tensors and compression members between the top and bottom chords of the truss.

Gold films are used as an alloying flux to form 5 micron thick film seals mostly below 300.degree.C. Pyrex was sealed to Quartz, ULE*, Cervit*, Germanium, Gallium Arsenide, (GaAs), invar and copper. The seals can also be used as current feed throughs and as graded seals and are particularly applicable to gas laser devices.

The compositions (toners) are useful in electrostatic printing and xerography and are a mixture of base and modifier particles with the base particles having a dielectric constant K and the modifier particles being of a normally solid, inert, non-hygroscopic, inorganic compound which compound has a dielectric constant K' of at least 10 and sufficient to give a K'/K ratio of at least 2 and an electropositive metal containing moiety chemically associated with an electronegative moiety. The metal o...

A shoe having an upper and a sole molded thereon with a disc molded in and rotatable in said sole and having a ground-engaging pad secured thereto and the method of coating the disc with a releasing agent, supporting the disc in the sole mold together with the upper so that the injection of sole material forms a sole bonded to the upper with the disc molded therein but because of the releasing agent is rotatable. This abstract is not to be construed in any way to define or limit the invention se...

A cartridge comprising a projectile and a cartridge case is formed with a neck at its forward end, and a sleeve-shaped holder for the projectile inserted into the mouth of the neck. A portion of the holder which is conically expanded by the insertion of the projectile bears against the inside of the neck of the cartridge case.

The specification and drawings disclose a load bearing structure and method for forming the same. In particular, the drawings show a catamaran-type sailboat including a pair of hulls having thin aluminum outer skin. The rigging, sails and deck are supported from rigid frame or load distributing members positioned within the hulls and spaced from their outer skin. Plastic is foamed in place in the hulls and encloses the frame members. The plastic foam bonds the frame to the skin of the hulls and ...

A building construction and method which utilizes columns and precast concrete, generally rectangular, horizontal floor slabs. A first set of columns is erected at the building site and post-tensioned. Then the horizontal slabs are lifted up and positioned with the corners thereof resting on the upper ends of the columns. In the preferred embodiment, each slab has a vertically extending pin secured to the slab at each corner. After the slabs are positioned on the columns, a locking ring is dropp...

A brassiere is provided with two cups, one or both of which is filled with an integral, artificial breast. Each of such artificial breasts contains a substantially conical outer surface of foamed polyester material, filled with chips of foamed rubber substance to approximate the size and elasticity of the natural breast, and a back panel of flat material covering the base of the conical form. A number of flat leaden weights are attached to the inner surface of the back panel to bring the weight ...
