Abstract: In a process for producing asphalt-aggregate compositions in a conventional type dryer-mixer drum in which aggregate is exposed directly to flame and hot gases of combustion while it cascades in the rotating drum, and in which the flame and hot gases of combustion are directed into an input end of the drum, the improvement comprises separating the aggregate into a plurality of different portions or increments each having different particle size ranges, introducing the coarse or larger aggregate particles into the drum and directly exposing them to the flame, its radient heat, hot gases of combustion at the input end, and introducing the finer or smaller aggregate particles downstream from the input end and away from direct exposure to the flame and extremely hot gases in a temperature zone which will avoid overheating the fine particles.

Abstract: A speaker cabinet comprises an enclosure having a top, bottom, front, back and two side panels, each panel being contiguous with an adjacent panel along its four edges, and the front panel having a sound port and interiorally of which is mounted a speaker, an improvement comprising a sound post extending and wedged between the front and back panels, an elongated bass bar secured along its length to the front panel, a pair of elongated blocks, each extending between and contacting the front and back panels, one of the blocks being secured to the top panel along its length and the other block secured to the bottom panel along its length, and a support plate secured along the back panel and extending between the side panels.

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: Apparatus for forming a concrete shield around a sprinkler head is a frusto-conical shaped form having a removable concentric flexible sleeve therein. A rotatable trowel is positioned inside the form to smooth the upper concrete surface. An inverted cup adapted to fit over the head of the sprinkler during the concrete forming process prevents wet concrete from contacting the top of the sprinkler head.

Abstract: A liquid level control system for a hydrotherapy vessel has a pressure sensing device located in the vessel. The pressure sensing device activates a switch which shuts off the hydrotherapy pump when the water in the vessel drops below a predetermined level.

Abstract: A device for reducing firearm recoil comprises a case having an elongated interior chamber therein, a piston received in the chamber, a plurality of vanes extending from the piston surface, and a liquid substantially filling the chamber. The piston is supported between front and rear return springs. The device is inserted in a gunstock, and recoil energy of the firearm, when fired, is dampened or slowed as the case and liquid are driven rearwardly against the resistance of the piston.

Abstract: A custom grooming device has relatively opposing mirrors mounted on a base. A portable pistol-type hair dryer is mountable on the base; air from the dryer flows through a hose to an exhaust port located near one of the mirrors. The mirrors are adjustable in height and angle for viewing all parts of the head.

Abstract: A wallpaper paste applicator comprises a container having an inclined tray bottom portion along which a strip of wallpaper travels with its decorative surface facing downward. The paper is pulled through a slot in the forward portion of the apparatus formed by a vertically adjustable wall and the bottom of the tray. A quantity of paste is maintained on top of the wallpaper in the tray, and is distributed to the back of the paper by a flexible notched wiping bar.

Abstract: An improved intraocular lens comprises a plastic lens body and a plurality of flexible and memory retaining non-biodegradable strands, each strand having one end secured to the lens body and the opposite end unsecured. Preferably, the strands are composed of polypropylene. In cataract surgery, following either intra or extra capsular extraction, the lens of the invention is implanted in the posterior chamber.

Abstract: A wrist watch protector comprises a flexible wrist encircling band for covering the watch with a centrally located opening for viewing the face of the watch. A quick-opening flap secured to the top of the wrist band covers the watch crystal. Utilization of a watch-carrying band strap located between the band and the flap allows the protector to optionally serve as a watch band by threading the strap through the bracelet attaching pins carried by the watch body.

Abstract: The process of the invention comprises directly exposing asphalt-aggregate compositions to hot gases of combustion in which a resulting gaseous mixture comprises mineral particulate matter, nitrogen, carbon dioxide, water vapor, and volatile hydrocarbons resulting from exposure of the asphalt-aggregate composition to the hot gases of combustion, directing the resulting gaseous mixture to a treating chamber and injecting a flame into it. The apparatus according to the invention includes an elongated drum in which asphalt-aggregate composition is exposed directly to flame and/or hot gases of combustion therefrom, and means for exhausting the resulting gaseous mixture to a separate treating chamber.

Abstract: A device for exercising the lungs by forced inhaling or exhaling comprises a mouthpiece and a valve assembly incorporating a valve housing unit having a gas inlet port and a gas outlet port both communicating with a cavity in which a movable valve body is received and which valve body has a first passageway for directing gas between the inlet and outlet ports and a second passageway for directing gas between a by-pass port and the gas outlet port. The relative amount of gas passing through the gas inlet port and through the gas by-pass port is determined by the position of the valve body and can be regulated by moving the valve body. The device also includes means for monitoring the flow of gas passing through the gas inlet port and preferably the length of time of that gas passage, and means for counting sequential inspirations or expirations of the user during the exercise.
