Abstract: A method for treating process material can include introducing process material into two different vessels, raising the temperature within one of the vessels through the introduction of steam to heat the material in the vessel, and reducing the temperature in the one vessel while also increasing the temperature in the other vessel by venting the interior of the one vessel to the interior of the other vessel.

Abstract: An improved portable, large volume cement mixer that includes a self-supporting inclined plane secured atop a wheeled main frame that provides basic structural support without the need for ancillary lifting equipment. The inclined plane is constructed in upper and lower hinged truss beams, upwardly hinged for operation and downwardly hinged for transport. A trolley carrying a cement mixer drum is then movable along the length of the inclined plane during operation, whereupon large batches of cement may be mixed and dispensed into waiting local carriers or trucks.

Abstract: A large volume cement mixer that is readily mobile and can be set up for use with a concrete batch plant at a given location. The cement mixer is carried on an elongated frame having wheels on one end and a gooseneck connection on the front end for towing purposes. A longitudinally movable carriage is carried on top of the elongated frame and the carriage is adapted to carry a large cement mixer mounted thereon. In operation, the elongate frame is braced in approximately 45.degree. angle attitude as the carriage supports the cement mixer in generally horizontal, rotatable fixture. Hydraulic devices are provided for rotating the cement mixer during the mixing mode of operation and, after completion, the carriage structure is hydraulically controlled to move upward along the elongate frame to a dump position whereupon the cement mixer is rotated forward and the mixed concrete is allowed to fall to a discharge position.

Abstract: A vertical screw mixer consisting of an elongate container having a bottom, first end, a second end, and containing walls which extend between the first end and the second end. At least one opening whereby raw materials are directed into the container. A plurality of generally conical processing screws are positioned at spaced intervals between the first end and the second end. Each of the processing screws has an axis of rotation which is angularly offset from vertical by inclining the axis of rotation toward the second end of the container, such that a flow of material is promoted from the first end toward the second end. A processed material outlet is positioned adjacent the second end whereby processed material exits the container.

Abstract: A mixer having a drum and a motor drivingly connected to the drum. The drum is mounted on a pivotting arm in a cantilever fashion. The pivotting arm has a bushing coaxial with an axis of the drum. The pivotting arm has a cable channel formed therein so as to enable an electrical connection to the motor. The motor has a drive shaft in driving connection with a transmission connected to the drum. The motor has a stator secured to a flange affixed to the bushing. The shaft has an eccentric engaging the step-down transmission so as to cause the drum to rotate relative to a speed of the motor. The electrical connection extends through a hole in the bushing. The electrical connection extends to a switchplug of a pivot axis of the pivotting arm.

Abstract: The apparatus is capable of supplying curds continuously, and comprises: a horizontal channel with a tapered bottom, having a feeding auger arranged in the bottom and actuatable by motor means; several cradles with semicircular section, rotatably carried in a horizontal position in the channel above the auger, and having a diameter slightly less than the distance between opposite walls of the channel, and actuatable by actuator means to take a first position with their mouths looking upwards and a second position with their mouths looking downwards; and several cheesemaking tipping vats arranged side-by-side with the channel and adapted to pour curds into the cradles while the latter are in their first position.

Abstract: An improved tiltable rotating concrete mixing drum has a relatively flat rear conical charging zone, a front conical zone having a central discharge opening for discharging materials when mixed and a generally cylindrical central zone disposed between front and rear conical zones in which the overall length-to-diameter ratio is reduced. The improved mixing drum has two sets of mixing blades, one in the central or mixing zone and one in the front or discharge zone which is scoop-shaped and configured to increase the efficiency of mixing along the horizontal axis of the drum by increasing the overall mixing efficiency.

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: Certain improvements are provided to the mechanical aspects of a tilt mixer which include a novel boggy, adjustable roller arrangement on the drum track which produces an improved distribution of the stresses produced by the extremely heavy rotating drum which reduces the wear on both individual rollers and on the track. An unique dual staggered-tooth gear drive is provided having two spaced sets of teeth each addressed by a pair of motor shaft mounted drive gears on each of a pair of flanking motors in which the teeth of the two sets are staggered or offset by one-half of the gear pitch. This produces a tighter, quieter drive which has been found to reduce gear wear. In addition, a unique torque tube system which possess a great deal more strength than previous drum tilt axles is provided to support the pivotal action of the drum thereby enabling the tilt point of the drum to be moved forward toward the discharge end of the mixers.

Abstract: An improved integrally mounted and operated dust hood is disclosed for a tilt mixer which minimizes the environmental effect of dust formed in the mixer which escapes from the discharge end of the drum. The integrally mounted dust hood of the invention includes a shaped sheet metal hood member which is hinge mounted from the forward drum support and operates in conjunction with the tilting of the mixer.

Abstract: A pedal latching mechanism for a machine to mix mortar and plaster, which includes a latch activated by a pedal lever, the latch mechanism including a rod biased against the vertical surface of the drum of the mixer and engages with a protuberance formed by a piece of metal welded to the vertical surface of the drum and bent in such a way as to form an inclined plane.During the rotation movement of the drum for the unloading of the mortar, the latch which is locked by the pedal, remains in contact with the surface of the inclined plane at first and then with the vertical surface of the piece of metal. When the drum returns to the upright position, the latch resumes automatically its latching position against the protuberance since it is biased by a spring.

Abstract: Improved apparatus for mixing concrete or the like is described and includes a support frame, a rotational drive mounted to the frame, a drum liner support rotatably connected to the rotational drive and a drum liner connected to and supported by the drum liner support and comprising a container having one open end for receiving therewithin the material to be mixed.

Abstract: A portable concrete mixing and transport device comprises a trailer having wheels and a drum supported above the wheels, said drum being movable into and out of engagement with the wheels. Concrete mix carried in the drum is agitated by pulling the trailer with the drum in contact with the wheels, causing the drum to rotate. The drum may be tilted to allow pouring of the mix. The device allows for convenient and inexpensive transport and mixing of small quantities of concrete.
