Abstract: The addition of aqueous dilutions of a sulfonic acid source of 0.2% to 0.8% acid concentration to an aggregate or to a composition of asphalt and aggregate in hot asphalt plants enables a decrease in the amount of asphalt required in comparison to compositions not so treated while achieving comparable strengths and durability when the composition is laid down as road paving material. The improved distribution of asphalt reduces usage by 10% to 40% and permits the incorporation of additional finely divided material to achieve higher strengths, or, inversely, to permit a higher percentage of voids to exist in the completed materials so as to provide for a porous paving material with suitable strength. The use of water in quantities of from 1,000 gallons to 3,000 gallons per 100 tons of aggregate and a sulfonic acid source in quantities of from 0.5 to 8 gallons per 100 tons of aggregate to provide an aggregate-acid-water composition having an initial pH of less than 3.

Abstract: Solar parabolic reflecting troughs are formed from long strips of sheet metal by applying equal bending moments to each long edge of the strip to draw the metal into a parabolic shape. While maintaining the metal in parabolic form, the trough is stress relieved by heating.

Abstract: A therapeutic incentive spirometer comprises a spirometer body having an outer wall and an inner wall, separated by a passageway, an interior chamber defined by said inner wall, a gas outlet for directing gas out of the chamber, a gas inlet means for directing gas into the chamber.

Abstract: Soil compositions suitable for use as building materials and having significantly improved properties of thermal or energy conductants and energy resistance as well as improved stress, compression, bearing, sound absorbing and structural integrity characteristics comprise a soil combined with cellulose, sodium silicate, and potassium or sodium hydroxide in specific proportions. The composition may also include clay and mineral fillers, depending on the characteristics of the soil.

Abstract: An improved earthen composition suitable for building construction comprises soil, a sulfonic acid, cellulose and a cementing agent comprising a calcium cement such as Portland cement, lime or calcium carbonate and/or an asphalt cement such as asphaltic concrete, asphalt, or tar. The compositions are prepared in an aqueous mixture, which is then tamped or consolidated, and dried.

Abstract: A hand-held device for selectively lifting a dutch oven or the oven lid comprises an elongated handle having a prong member secured at one end, the prong member having a first leg extending at an obtuse angle from the handle and a second leg extending at an acute angle therefrom, and a heel member secured on the second leg. The device is used for lifting an oven lid by directing the first leg beneath the lid handle with the heel resting on and stabilizing the lid. The oven is lifted by catching the bail on with the slanted second leg and lifting up.

Abstract: A card deck comprises high and low red and black cards, high cards having an indicia thereon and low cards lacking such indicia, and high cards of a third color, preferably gold or silver. In a preferred deck, there are 16 low red cards, 16 low black cards, 8 high red cards, 8 high black cards, and 4 high gold cards. The invention includes game board playing surface for selecting or guessing different cards or hands to be dealt by a dealer.

Abstract: A system for transporting baggage, or other articles, comprises a trailer having a plurality of cases secured thereon, each case for receiving two baggage containing mobile capsules, having a lift means for elevating and holding one of the capsules above the other capsule within the case, a ramp and conveyor for engaging a capsule at ground level and moving the capsule along the ramp into the case, and drive means associated with the system for the lift means and conveyor.

Abstract: An improved apparatus for recycling asphaltic concrete includes an inclined chute for introducing composition into an open port into which a burner also feeds hot gases of combustion. The apparatus provides for improved continuous processing by feeding composition containing relatively large particle sizes into the open port and recovering heated composition adjacent the opposite drum end.

Abstract: A hair curling device combines a larger roller member comprising first and second crescent-shaped cylinder portions, each having a slot extending along their respective lengths and defined between two substantially parallel edges and along which the two cylinder portions are attached, the first cylinder portion having a greater diameter than the second cylinder portion, the second cylinder portion being secured interiorly of the first cylinder portion, whereby the second cylinder portion defines an elongated slot in which a second and relatively smaller roller is removably secured. The slot diameter is critically greater than the smaller roller diameter, and in a preferred embodiment, the slot is provided with a plurality of nipples or ribs for maintaining a spacial relationship between the smaller roller and slot surface.

Abstract: In a process for producing asphalt-aggregate composition in which used asphaltic concrete is recycled by being heated and mixed in a rotatable drum into which flame and hot gases of combustion are directed, the improvement comprises introducing virgin aggregate in a hot zone of the drum and directly exposing the aggregate to the flame and/or hot gases of combustion, and introducing particles of asphalt-aggregate composition downstream from the hot drum input end, away from direct exposure to the flame and extremely hot gases, in a cooler temperature zone. An improved apparatus includes means for introducing the aggregate at the input drum end for direct exposure to the flame or hottest gases, and means for introducing the used and recycled asphalt-aggregate composition in a cooler drum zone.

Abstract: Custom bathing vessels are preformed away from the job site by constructing a structural plywood shell, and coating the inside of the shell with a fiberglass/resin mixture. The unit is shipped to the job site, where an asphalt-impregnated felt membrane and a surface coating, such as tile, are applied.

Abstract: Automatic fishing apparatus has a rod-holding tube concentrically mounted in a pivoted sleeve which is biased toward an armed position. A solenoid-actuated latch maintains the sleeve in the armed position. The tube is separately biased in the sleeve to permit movement of the tube against a trigger which actuates the solenoid. A calibration circuit permits adjustment of bias on the tube when the tube is in the cocked position.

Abstract: An apparatus for heating and mixing an asphalt-aggregate composition comprises a drum rotatable about an axis, having a mixing and heating chamber with a restricted port at one end into which a flame and hot gases of combustion are directed and through which exhaust gases simultaneously pass to atmosphere, and a heating means comprising a burner nozzle for directing flame and the hot gases of combustion into the chamber at the restricted port. The nozzle is adjusted relative to the port whereby the volatiles from the asphalt are ignited and burned within the mixing chamber prior to being vented to the atmosphere from the restricted port. Composition may also be introduced and/or removed from the chamber through the restricted port.
