Abstract: A starch-based alkaline curing adhesive is disclosed. The adhesive, when employed in the preparation of corrugated paperboard provides the paperboard with superior water resistant bonds. The adhesive contains from about 6 to 35%, based on total weight of the adhesive, solids basis, of a latex polymer of a halohydrin quaternary ammonium monomer.

Abstract: A rotary internal combustion engine capable of operating under compression ignition, comprises a cylinder bore in a stator sealed between parallel end walls, an engine shaft journaled in the end walls, concentric with the cylinder bore, an air-compressing rotor keyed eccentrically to the engine shaft, the rotor generally annular, traveling clockwise, a wiper vane across its head sucking in air through a one-way inlet port in the perimeter of the cylinder bore, at the same time compressing the air ahead of it which was inhaled during the preceding revolution.

Abstract: The invention engine comprises a compressor with a rotary piston in a cylinder bore in a stator and a U-shaped box-like combustion-expansion compartment, conveniently called a U-box, immediately above and riding on the rotary piston, the U-box and the compressor unit contained between the same parallel end walls. The rotary piston is eccentrically mounted on a shaft which is concentric with the cylinder bore and is supported in bearings in the end walls. A wiper blade is fitted in a groove across the piston head to yieldably sweep the cylinder bore to generate a suction stroke behind it, drawing in air via a one-way inlet port in the perimeter of the cylinder, and a compression stroke ahead of it to compress the air drawn in during the preceding suction stroke. The U-box is in the shape of a rectangular plate bent upward at two places to form two parallel vertical sides of equal height and a base plate between them.

Abstract: A rotary internal combustion engine comprising a cylinder bore in a stator sealed between parallel end walls; a power shaft concentric with the cylinder bore journaled in bearings in the end walls; an annular eccentric piston fixed onto the engine shaft just clearing the end walls and the cylinder as it rotates. A first abutment with one end pivotally anchored in the stator near 10:00 o'clock, the other end projecting clockwise and free to swing vertically in the cylinder space, seals the space between the cylinder and the piston from end wall to end wall, forming the counter-clockwise end of a combustion-expansion chamber. A second abutment, pivotally anchored in the stator near 2:00 o'clock, its free end projecting counter-clockwise and sealing the space between the cylinder and piston from end wall to end wall, forms the clockwise end of the combustion-expansion chamber. Both abutments are spring biased downward toward the piston.

Abstract: In the novel method, before an electron-gun mount assembly is sealed into the neck of a CRT, at least the high-voltage electrodes and the adjacent portions of the focus electrodes are dipped into an aqueous solution consisting essentially of hydrogen peroxide and water. The solution contains substantially more than 10, and preferably about 30 to 50, weight percent of hydrogen peroxide.

Abstract: A rotary internal combustion engine comprising a cylinder in a stator sealed between parallel end plates, a power shaft concentric with the cylinder bore and journaled in bearings in the end walls, an annular eccentric rotor fitted onto the shaft, and an annular piston concentric with and fitted over the rotor making sliding sealing engagement with both end plates. An abutment centered preferably between 10:00 and 10:30 o'clock on the stator seals the space between the cylinder and piston from endplate to endplate and forms the counterclockwise end of a combustion-expansion chamber. A second abutment, centered preferably between 1:30 and 2:00 o'clock, seals the space between the cylinder and piston from endplate to endplate and forms the clockwise end of the combustion-expansion chamber. The combustion chamber centered at 12:00 o'clock comprises a shallow arcuate cavity adjacent the path of the piston and opening into the cylinder.

Abstract: The present invention provides a solar heating system which is particularly suited for use in a building, such as a greenhouse, having walls defining an enclosed interior with at least one of the walls including a light transmissive area for admitting light into the interior of the building. In accordance with the invention a solar heat collector is positioned underlying the light transmissive area of the building wall, with the collector comprising a plurality of elongate radiation absorptive heat conductive elements for receiving solar radiation and being heated thereby. The heat conductive elements extend longitudinally downwardly and are positioned in laterally spaced relation from one another for admitting light therebetween into the building while also serving for partially shading the interior of the building.
