Abstract: The invention is an apparatus for mixing fluent material. A hopper is pivotably mounted to a frame on a pivot axis that is substantially spaced from the axis of rotation of a mixing paddle. Because the pivot axis is substantially spaced from the axis of rotation, the mixer can be loaded by the operator at a low charge height and subsequently dumped at a higher dump height. Horizontally adjustable arms in combination with vertically adjustable legs provide for adjustability in length, width and height of the apparatus for stability when the hopper is fully dumped.

Abstract: A bearing and seal assembly for supporting and sealing end portions of a rotatable paddle shaft in the end walls of a mortar mixer or the like. Each bearing and seal assembly includes a bearing and seal housing removably attached to an end wall of the mixer drum by bolts to facilitate replacement of the bearings and seals as becomes necessary during use. The outside wall of the housing includes a peripheral ring or shoulder for engagement with a conventional bearing puller to facilitate removal of the housing, bearings and seals as a single unit. Preassembled housing, bearing and seal units can then be used as replacements. The bearings and seals are also spaced longitudinally to provide a space for abrasive materials that may migrate past the seals to extend the life expectancy of the bearings by decreasing exposure to contamination.

Abstract: In order to make good-quality concrete, a concrete mixer for mixing materials of concrete by rotation is provided so as to enhance fluidity of a mixture. A mounting frame 7 supporting a drum 2 of a concrete mixer 1 fixes a vibration device 25 via a mounting plate 21. A pair of arms 20 is integrally formed with both ends of the mounting plate 21, while rollers 24 rotationally supported by one ends of the arms 20 respectively contact the outer periphery of the drum 2. A vibration of the vibration device 25 is transmitted from the rollers 24 rotatably supported by the pair of arms 20 to the drum 2, so that the drum 2 vibrates while it rotates. Accordingly, a mixture is liquefied, and thus concrete having a good quality can be produced.

Abstract: A portable mixing device for quickly and efficiently combining dry constituents with water to form a mix having a thin batter consistency and no unmixed material. Mounted on a wheeled, pivoting frame, a single individual can use the device to mix the material and pour it in the proper location. The device includes a cylindrical mixing drum and agitation tool mounted within the mixing drum. The agitation tool includes a motor and housing, a drive shaft, wiping assembly, and mixing assembly. The stationary wiping assembly, which extends downward into the mixing drum co-mingles so as to pass closely between and among the blades of the rotating mixing assembly such that the flexible edge portions of the wiping assembly blades are in intermittent contact with the blades of the mixing assembly. The “wiping” action of the wiper assembly on the mixing assembly insures complete and efficient agitation and mix of materials.

Abstract: A portable apparatus adapted for use in filling chuck holes in paved surfaces with a sulphur-based material that has been heated to a plasticized condition. The apparatus includes an electrically heated furnace in which an auger is mounted for the purpose of moving a sulphur-based material through the furnace at a controlled rate (e.g., about 2 feet per minute), such that the material will be elevated to a temperature of above 305 degrees Farenheit (the melting point of sulphur) to produce a tenacious filler material. The furnace is heated by tubular resistance heaters that are bent in a spiral fashion around a mandrel, so that they may be placed in intimate contact with the exterior of a tube which constitutes the core of the furnace. The furnace is fed by a hopper that is mounted above the entry point for the auger, so that dry material may be fed--by gravity--into the furnace whenever a gate-valve mechanism is opened.

Abstract: A system for adding a predetermined volume of particulate material to a reactor which includes an inclined track mounted on the reactor such that a lower end of the track terminates adjacent an opening in the reactor, and a slideable container mounted on the track for sliding movement from an upper end of the track to the lower end of the track, the container having an internal volume equal to the predetermined volume, and having a forward wall which can be opened to discharge the contents of the container.
