Abstract: The invention relates specifically to an improved method of joining plastic socket fit piping components for vacuum, pressure, and structural applications where a leak and contamination free connection is needed. A unique Dual Face/Circumferential Elastomer Seal is installed in a special Seal Groove located on the end of the male component. The male components are then inserted into the female sockets until contact is made between the Dual Face/Circumferential Elastomer Seals and the Female Socket Base Surfaces. The final assembly is evacuated with a vacuum pump to actuate and fully compress the seals. The final assembly is then checked for leaks. If the connections are to remain under vacuum and the ability to disassemble is advantageous, no further work is required.

Abstract: A light-up coaster for beer bottles, and the like, has an outer housing in which is vertically-slidable an inner housing. The upper surface of the inner housing is used to support a bottle thereon, and a spring biases the inner housing upwardly. A pair of switches are controlled by the movement of the inner housing. The first switch is a normally-closed switch, and the second switch is a normally open switch. The two switches are arranged in series with a light bulb and battery power-source. When there is no bottle supported on the upper surface of the inner housing, the upper surface of the inner housing is raised by the spring to its highest level and into abutting contact with an interior, upper, annular lip of the outer housing. In this state, the first switch is closed but the second switch is open.

Abstract: A method of producing a truck-like conversion van starts with a conventional, cargo van, and vertically cuts the conventional van only partially along a vertical section of the main frame of the vehicle, just rearwardly of the side doors of the van. Thereafter, a horizontal cut is made starting from the bottom of the vertical cut and progressing rearwardly all the way through the frame or existing floor of the van. Thus a rectangular-shaped slab or cutout of the conventional van is removed. The horizontal plane in which the horizontal cut is made is above the top of the rear tail lights, so that, not only are all of the mechanical parts of the original van retained, but also the same, original tail lights are also retained. After the slab has been cut away and removed, a truck-bed liner-insert of the invention is inserted into the cut-away, rear portion of the van, which rear portion is partially hollow, by which the liner-insert may be received therein.

Abstract: A dual-section nozzle-head for use in a vacuum-packaging machine. The first section of the nozzle-head is provided with an interiorly-located manifold, that fluidly connects a series of first orifices, the exit-ends of which are located at the tip of the nozzle-head, so that these orifices may be fluidly coupled to the interior of packages at a sealing station of a vacuum-packaging machine for evacuating the packages via a vacuum source to which the orifices are connected. Interspersed between these first orifices are second orifices, which also have their exit-mouths at the tip of the nozzle-head. The second orifices are spaced apart, one from the other, along the length of the nozzle-head, and are coupled to a second manifold that is positioned exteriorly of the housing of the nozzle-head. The second manifold is coupled to a supply of protective inert gas.

Abstract: A method of separating a lighter gas from heavier gases. A series of pumps is used. A gas to be separated out from a mixture of gases is introduced at an exhaust port of one of the pumps, with the lighter gas among them traveling upstream into a container.

Abstract: A device for squeezing out the contents of a tube, such as toothpaste. There is provided a flat, lower frame upon which is supported a squeezable tube whose contents are to be dispensed. Extending upwardly from the top, flat surface of the frame are two pairs of two guide-posts. The two pairs of guide-posts are aligned and are spaced apart along the length of the top surface of the frame. The two-guide posts of each pair are laterally spaced apart, whereby a tube may be inserted on the top surface and between the upstanding posts of the pairs of guide-posts. Mounted for manual, vertical movement along the two pairs of guide-posts are a pair of spaced-apart slide-blocks, one such slide-block for one such pair of guide-posts. Each slide-block has a pair of oppositely-disposed through-holes through which pass the two guide-posts of the respective pair. Both slide-blocks are used during the dispensing of the contents of a tube positioned on the top surface of the frame, between the guide-posts.

Abstract: A plurality of pairs of identifying tags are provided. Each pair is made up of two identical tags, with each tag of each pair having a main, elongated, body-portion, preferably made of plastic, such as polyvinylchloride, in which is embedded a thin, elongated strip of flexible, pliable steel wire. In the preferred embodiment, the main, elongated body-portion is formed along a portion of its length with toothed projections which serve in aiding to retain the tag in a hole, when the respective tag is to be used for identifying a hole associated with a mating screw. The embedded steel wire helps to retain the shape of the tag when the tag is bent or wrapped about a workpiece or component being identified. In one embodiment of the invention, the ends of the steel wire project outwardly beyond the ends of the plastic main body-portion, so that the ends of the wire may be twisted together to removably hold tag on the workpiece or component being identified, after the tag has been bent thereabout.

Abstract: A pair of spaced-apart, parallel rings is provided, with each ring provided with a plurality of semicircular loop portions pivotally connected to the respective ring about its circumference. Each ring has two sets of a plurality of semicircular loops, a first outer set that is pivotal in a first direction away from the other ring, and a second inner set that is pivotally connected to the first set of loops of the other ring. The loops of each set are arranged in an overlapping manner, so that when one of the loops is rotated, all of the loops of that set are concurrently rotated. Since the inner sets of loops of the two rings are pivotally interconnected, rotation of any loop of either of the two second inner sets will concurrently rotate the other loops of the second inner sets. Rotation of these loops of the second inner sets is achieved by drawing closer the two rings or by pulling them apart. The two first outer sets of loops are free to rotate in either direction.

Abstract: A barricade or barrier for road-warning signs, which utilizes just one vertical, mounting support-pole to which is mounted the road-hazard or road-warning sign, or the like. The single, vertical support-pole is mounted to a base made of a used tire by means of a pair of bracket-arms, with the two bracket-arms being vertically spaced apart and extending transversely to each other. The two bracket-arms are bolted to the used-tire base, with the upper bracket-arm being bolted to the upper, annular surface of the used tire, and with the lower bracket-arm being bolted to the bottom, annular surface of the tire-base, whereby the two bracket-arms sandwich the tire therebetween for a strong, stable mounting of the support-pole secured to the two bracket-arms. The support-pole is removably mounted to the mounting bracket-arms, and itself is modular in construction to allow for easy assembly and disassembly, and to ensure proper mounting of the two bracket-arms to the tire-base.

Abstract: An improved tool for pulling off a rotor of a motor from a shaft or a fan from a shaft, which improved tool is provided with hooked arms that are releasably but securely held at one end in the housing, without the use of retaining clips, so that the arms do not fall off during use or become lost, and so that they do not interfere with the use of the tool when using the securing bolts for pulling off a rotor. The hooked arms of the invention are also hexagonal shaped, and securing bolts are provided with hexagonal-shaped recesses in their heads, so that the hooked arms may themselves be used for rotating the securing bolts when pulling off a rotor of a motor from a shaft.

Abstract: A switch for connecting a load to a power source has a first rotatable ratchet wheel which meshes with a unidrectionally rotatable second ratchet wheel, which meshes with mating teeth on an interior-facing surface face of a stationary ratchet face. The ratchet wheels are biassed together via a spring such that one end may be brought into contact with a load, while the other end is in contact with a power source. The switch moves the one end into or out of contact with the load for making or breaking the electrical circuit.
