Abstract: A spout for a container is provided with depending wings extending down from a bottom edge of the spout. The depending wings terminate in a point for piercing a container. The depending wings permit the spout to pivot ninety degrees from the container to extend from a container at a ninety degree angle therefrom. The spout has side walls with upper edges having arcs of ninety degrees. The spout is inserted into a container with a ram which drives the spout against a ramp to rock the depending wings upward with respect to the bottom edge of the spout. Thereafter, the ram drives the points into the container and the upper edges of the side walls of the spout contact the container and cam the spout back to a horizontal position to insert the ninety degree spout with the depending wings into a container.

Abstract: A low friction, dry lubricant impregnated anti-extrusion apparatus for engagement with an annular seal or packer, wherein said packer is used to seal the annular space of a well or pipe bore. The low friction, dry lubricant impregnated anti-extrusion apparatus being designed to generally avoid absorption of the compression setting forces, wherein the compression setting forces are in turn substantially transmitted through the anti-extrusion apparatus to the packer to effect radial expansion of the packer to seal the annular space, while generally preventing the extrusion of the packer at high pressures and avoiding high frictional contact between the anti-extrusion apparatus and an inner surface of the well or pipe bore.

Abstract: A method for fabricating protective seals or "boots" for electric switches, such as push button and toggle switches, is described. In place of traditional rubber molding techniques, the seals are made by thermoforming a plastic film, preferably polyurethane, over a mold containing the nut portion of the seal and pins configured for a suitable shape for toggle or push button switches. Inexpensive stamped, threaded nuts can be employed, and this, together with reduced tooling costs and the efficiency of the method, produce extremely economical electric switch seals. The seals themselves offer unique benefits in that the thin, yet tough, plastic film does not interfere with the functioning of the switches, while providing prolonged service life under difficult conditions. Utilizing clear urethane film, the resultant seals provide clear viewing of the functioning of the switch within.

Abstract: An extendible and tiltable shim is provided having a hingeably connected leg that is extendable. The leg can extend to adjust the height and the angle of the shim. The shim is mounted to a structure member and abuts to a frame member. The structure member can comprise a rough opening in a wall. The frame member can comprise a door jamb or a window jamb. The method of the invention includes an initial step of attaching the bottom plate of the shim to a structure, extending the leg to contact the frame member, and adjusting the extension of the leg to center and plumb the frame member. The shim accurately and reliably adjusts a door jamb or window jamb within a rough opening in a wall for proper alignment. The shim tilts at an angle and offsets to accommodate crooked and misaligned wall structure. The shim can easily retrofit to a standard door jamb or a window frame for the purpose of aiding in the square alignment of the door jamb or window jamb within a rough opening in wall structure.

Abstract: A method for applying a high moisture permeability floor covering material to a concrete surface and product thereof. The method comprises the steps of first applying a layer of inert fibers to the concrete surface. To the fiber layer is applied an aqueous acrylate polymer emulsion to form localized bonding penetrations of the emulsion through the layer of fibers to the concrete surface and to form a continuous coating of emulsion on the upper surface of the layer of fibers. The coating is applied so that the coated fiber layer has interconnected moisture transmission passageways communicating with the concrete surface and extending throughout the fiber layer for redistributive diffusion under the continuous coating of moisture vapor from high emission surfaces of the concrete to lower emission surfaces of the concrete. A further layer of high viscosity aqueous acrylate polymer emulsion is applied to said continuous coating and set.
