Abstract: A frame member, as is used for office and other furniture, such as desks, chairs and other components, is formed from a length of rigid tubing, of polygonal cross-section, and bent on a diagonal. The tube is bent by bending around an arcuate bending member having a peripheral groove which is a cross-section corresponding to about half the cross-section of the tube. The tube is gripped against the periphery of the arcuate bending member, by a gripping member, the bending member and gripping member moving about an axis to bend the tube. The tube is held in contact with the arcuate bending member by an elongate bending member which is slidingly supported on a fixed base and moves with the tube over the fixed base as bending progresses. The tube is supported against collapse by a stationary internal non-deformable member.

Abstract: An arrangement for retaining and positioning a tapered journal sleeve or bearing on the tapered journal of a rolling mill roll utilizes a circumferential groove in the cylindrical end of the roll, in which groove a number of cylindrical rollers are placed. The rollers have a diameter which is greater than the depth of the groove. Thus the rollers project outwardly from the groove and act as a stop for an extractor sleeve. Hydraulic fluid is used to force the tapered journal sleeve onto or off of the tapered journal of the rolling mill roll.

Abstract: A bundle of three or more rows of end-joined cans (preferably in multiples of two rows) arranged around an axis of the group, clamped into a unit by flexible ties, such as: loops of adhesive strapping tape: apertured strips or tapes of thin metal, cloth or plastic, with tape ends fastened together by adhesive on the tape, or bolts, rivets or the like thru tape-end or network apertures, or snap fasteners with a stud on one end of each cloth or plastic tape loop and a crown on the other: loops of cord with bands; or the like. This bundle may be used on the tubular framework of a wall, ceiling or roof of a stationary building, mobile home, trailer or vehicle, the framework preferably stuccoed on one side and stuccoed, plastered or otherwise wall-finished on the other.

Abstract: An upright-wall, ceiling or roof made of panels fastened together along contacting panel edges. Each panel is made of a can-supporting planar element (a sheet of plywood, masonite, plastic or the like), reinforcing bars defining outer edges of the panel, cans between the reinforcing bars, wide-mesh wire or plastic panel-reinforcing network on the cans, and molded matrix material (foamed, cellular, polyolefin plastic, or concrete of portland or other cement and sand or porous aggregate -- for example, cinders, vermiculite, pumice, charred sawdust or the like) on the cans. The can-supporting element is placed in a mold, cans are put on this element optionally parallel to it but with their axes preferably perpendicular to it, the wide-mesh network is placed on the cans, and the moldable plastic material in fluent form is poured or injected into the mold thru the wide mesh of the network around the cans and on the network.

Abstract: A contruction member, usable in exterior or interior walls, ceilings or floors, including: a stiff, planar, can-supporting panel or board; cylindrical or otherwise non-rectangular, parallel-axes cans having end covers fixed to the panel or board, these cans being preferably of metal but optionally of dense, strong plastic or glass, of the new or used type, having lengths that are less than twelve times their diameters; optional insulation inside the cans; large-mesh metal or plastic fencing, fixed to can ends; and porous, insulating, strength-providing adhesive material around portions of the can sidewalls, bonding and bracing the cans together into a bar, panel or block, part of this material being in layers within recesses of the can-end covers that are spaced from the panel or board.

Abstract: A simplified, economical vehicle is disclosed. A steerable front wheel, on the side of the vehicle toward the center of a roadway, is turned by motorcycle-like steering forks. A single powered rear wheel, aligned with the front wheel in a fore-and-aft driving axis, is driven, without a differential, by an electric motor or other motive power. In three of the inventive forms there is only the one front wheel; in another, preferred form there is at least one other front wheel, on the side of the driving axis away from the center of the roadway. It is optionally on the ground all the time during land travel -- or, optionally, normally clear of the ground and contacting it only when the vehicle tilts dangerously toward this wheel. It is swivelly mounted for turning into the plane of vehicle motion. Optionally, there is a second front castor wheel, on the side of the steerable wheel toward the roadway center.

Abstract: A method and apparatus for removing entrained matter from the intake air of a chain saw internal combustion engine of the type including at least one piston and cylinder, a crank shaft, and a carburetor.The apparatus includes a shroud surrounding at least one end of the crank shaft with an air inlet fashioned into the shroud at a position adjacent to said one end of the crank shaft and an air outlet fashioned into the shroud at a position remote from the air inlet. An air passage opens into the shroud adjacent the crank shaft for providing fluid communication between the interior of the shroud and the carburetor. The crank shaft is provided with a hub having on opposite faces thereof a first and second cascade of radial flow compressor blades to centrifugally impel air and entrained particulate matter away from the crankshaft. The compressor blades serve to remove at least a portion of the entrained matter from the combustion inlet air prior to the air entering the air passage for delivery to the carburetor.

Abstract: A winged aircraft, adapted to takeoff and land with its longitudinal axis at a very steep angle of inclination, including: balloons that have a center of buoyancy forward of the center of gravity and tend to turn the craft into the said steep angle; a controllable-thrust stern-elevating propeller in an upright wind tunnel, having a lift rearward of the center of gravity that in horizontal flight balances the torque of the balloons; and an elongated, stiffly resilient body frame of a multiplicity of inflated small tubes extending in the fore-and-aft direction, supported by longitudinally spaced, rounded ribs, disks or the like. This frame is round in the middle and somewhat streamlined at each end, its stern portion rearwardly sloping downward at its top and upward at its bottom. The assembly of tubes, preferably extending from the foremost to the rearmost parts of the frame, is flattened into substantially linear, horizontal shape at the rear portion.

Abstract: A low-cost building, building section or wall, usable as a house, mobile home, vehicle, or part of these or other structures, having numerous parallel rows of end-joined used or new cans, each can preferably consisting of a tube and can-cover elements at ends of the tube and containing thermal insulation, which may be only dead air in the relatively small hollow can space but preferably includes loose small portions of low-cost insulating material, such as sawdust, vermiculite, cotton linters, dry sand or dust, ashes, cinders, ground bark, rice or other seed hulls. Abutting pairs of can cover elements are tightly held together by connecting means which may be bonding material (epoxy putty, solder or the like) or bands of slightly stretchable adhesive tape which encompass and adhere to portions of juxtaposed pairs of the end-joined cans. A layer of mesh sheathes one side of each group of the can rows, and the other side is sheathed with wall material which may be mesh or insulating solid panels.
