Abstract: Improvements made to wheeled skate-skis with brakes usable on most terrains are: a hand controlled hydraulic fluid braking assembly, having a sole, resilient, curved spring, brake shoe, providing performance in comparison with the braking performance of a roadway motor vehicle; a chassis with a foot receiving body portion formed on a convex camber and made of materials which are flexible, under the weight of a person, thereby providing a spring like suspension, and with upwardly directed curved forked ends to position wheel axles higher above the ground to lower the foot receiving body portion, to thereby lower the center of gravity of the sportsperson, while moving on the wheeled skate-skis; a binding which is a combination of an outer shell of a firm material and an inner liner of soft material, which together are adjustable to fit different sizes and types of athletic shoes selected and worn by sportspersons; and a removable mud flap supportable on the binding to deflect water and/or debris thrown by a rea
Abstract: A laser lighting assembly, mounted on a forklift, will be projecting a light beam parallel to and in the same plane as a fork, which itself is parallel to a floor or ground level. Until the forks are parallel to the floor or ground level the laser light will not be continuously on. When an operator of the forklift is adjusting the forks to be level, and then parallel to the floor or ground level, as the level positions are being approached, the laser light appears in a blinking sequence with the off periods initially being longer and then becoming shorter as the level positions are approached. Then when the level positions of the forks are reached the laser light is on full time.
Abstract: Asphaltic concrete compounds comprised of asphalt cement and aggregate have, as a substantial portion of their respective aggregates, anthracite coal particles and fines, which are added specially as a lossy microwave material. These asphaltic concrete compounds are particularly useful when laid down as a pavement, or a top layer of a pavement, which thereafter can be freed of ice, by using microwave energy to debond the ice. The debonding of the ice occurs without causing any noticeable melting of the ice, and the debonded ice is thereafter easily lifted and removed from the pavement of the way, serving as a roadway, highway, runway, or walkway. Also these asphaltic concrete compounds are particularly useful as patching materials when damaged pavement is being repaired, especially during cold weather.

Abstract: Shipping and storage pallets and for handling goods and products are made of corrugated cardboard and corrugated plastic board arranged in respective vertically positioned side by side adhered laminations, which are die cut in respective patterns, to create both longitudinal members and transverse members, which are interfitted, via die cutout portions, to form a main pallet support. There are different sizes of different strengths and different configurations of these main pallet supports. Also the main pallet support, in addition to being shaped to receive tongs of a forklift, are also shaped to position different items of specific shapes, such as cylindrical shapes. Both the longitudinal members and transverse members, in some embodiments, include surrounding sleeves of wall corrugated materials. These various pallets are movable by using forklifts, preferably approaching in one of at least two different directions, which are perpendicular to one another.
Abstract: A laser lighting assembly, or another type of a directed high intensity collimated beam of light assembly, mountable on a forklift, or like purpose lifting and carrying equipment, to project at least one light beam, which is always directed parallel to and in the same plane as a fork or pair of forks, which are movably mounted on the lifting and carrying equipment for being raised and lowered. The projected light beam, during operations of the forklift, reflects from a changeable spot location on a load to be lifted, which is supported on a pallet, or is supported on a like fork receiving structure. When the fork is being either raised or lowered to be inserted, for example, in a fork receiving volume of a pallet, an operator of the forklift is observing the changeable spot location.
Abstract: An adjustably directable clean air delivery supply assembly which provides clean air for use in weather protected environments. This assembly is, doorway passable and rollably positioned, to be utilized where activities require very clean air per strict specifications. When located, the device can quickly be unfolded and positioned for operation to produce clean air in the desired direction at minimal-eddy producing airflow. Surrounding unfiltered air is drawn in just above floor level through a pre-filter into a airtight lower hollow housing, which contains an interior powered air moving assembly, and discharged upwardly into the tower hollow housing which is supported on top of the lower hollow housing. Secured to the tower hollow housing is an adjustable telescoping height and rotatable positioning structural tube, which receives and directs the air upwardly through a self-sealing bellows into the top final filter hood assembly.
Abstract: An improved corner-rounding milling cutter preformed indexable and insert therefor.

Abstract: A combined vapor barrier and water assembly for securement to the underside of covers of heated water tubs and pools stands by and around an intentionally made drain opening in an otherwise water tight cover, to provide a drain passageway to be used, if necessary, whenever rain water might unwantedly enter the interior of the cover, and while standing by, to provide a vapor barrier preventing heated vapors from rising upwardly through the drain passageway. In a preferred embodiment, at least two dense weave cloth members, spaced apart, each extend completely across the cross section of the drain passageway, while positioned within a hollow contoured housing of the assembly, which is adapted to be secured to the underside of the cover round the intentionally made drain opening, to provide the drain passageway for the exiting rain water that might unwantedly collect in a cover which was originally watertight.
Abstract: A butterfly damper for installation in duct work through which air and/or gases will be flowing either under a positive or negative pressure has: an outer cylindrical surface structure made of a fixed strong material; an inner flexible cylindrical surface structure made of a resilient material; a circumferential portion of compressible material, which is always tending to return to the non-compressed form thereof, which is initially compressed between the outer cylindrical surface structure and the inner cylindrical surface structure, whereby the inside diameter of the duct body portion, initially, is uniform throughout the length thereof, and, thereafter, when the initial compressive force becomes less effective, the compressive material expands causing radially inward movement of adjacent circumferential portions of the inner flexible cylindrical surface structure; a blade to be moved across the flow of air and/or gases into sealing contact with the radially inwardly moved circumferential portions of the in

Abstract: When a dental patient is having one or more of his or her front teeth aesthetically improved, when a dentist cements thereon a porcelain veneer, which becomes a porcelain laminate extending across the front surface of the patient's tooth, the method steps followed and the equipment used have been improved. The improvements center both on obtaining more quickly and more accurately a noble metal foil matrix, which conforms to the front surface of the front tooth die of the patient, and on applying the porcelain ceramic slurry on the conformed noble metal material, to compensate for the shrinking of the porcelain during the firing thereof. The improved equipment is a forming machine which utilizes a constant pressure source of compressed air to move a piston in a cylinder, with the piston moving one metal die to contact another metal die, each die having an aligned rubber insert, and each rubber insert having an alike aligned receiving space.
Abstract: In restrained sealed bolted joints of fluid piping systems, including both plastic and metallic pipe, improvements have previously been made in providing adequate grip rings to keep the inserted ends of pipe in place. When larger diameter pipes, especially larger diameter plastic pipes, were inserted into these sealed bolted joints, some difficulties were encountered. Therefore, a compression control ring is now provided to controllably transfer and to limit the tightening force component, which moves the gasket into sealing contacts with the respective pipe sections being joined. Also circumferentially spaced skid pads are positioned about each grip ring, assuring each respective grip ring will not prematurely commence gripping a pipe. In addition, the gland has been improved, so any possible large assembly forces, or any large fluid pressures in the piping system will not be effective in distorting the gland.
