Abstract:
An assembly is mounted to a soft serve confection freezer. It includes a set of modules in a circular array and separately replaceable in a magazine. Each module supports a container storing a dry food ingredient in particulate form, and has a motor driven product impeller for controlled discharge of particulates from the container to a blender assembly. The blender assembly has a housing and screw-type auger of cooperating configurations and which cooperate with a central passageway for frozen confection flowing from the freezer, to blend solids into the confection and discharge into a customer's container for immediate consumption. Control panel selection of ingredients by the operator according to the customer's order, is provided. Components are arranged to facilitate cleaning.
Abstract:
A polycondensation reactor for processing low viscosity polyester or another polymer into relatively highly viscosity polymer comprises a substantially cylindrical horizontal reactor vessel with a polymer inlet and a polymer outlet adjacent its opposite ends and a vapor exhaust opening in the upper side of the vessel at its outlet end. A polymer agitator is rotated axially within the chamber and includes plural alternating annular overflow and underflow baffles and multiple perforated film-forming screens disposed therebetween in parallel spaced relation to one another. The overflow baffles are in peripheral polymer-sealing relation to the vessel while the underflow baffles have multiple underflow recesses in their outer peripheries, whereby the baffles define a tortuous polymer flow path alternately through their respective polymer overflow and underflow openings to control residence time, distribution and viscosity growth as the polymer flows between the baffles. The baffles and screens are integrally fixed coaxially at their outer peripheries by axially extending wiper bars. Aligned openings in the baffles and screens along the rotational axis of the agitator provide for free flow of volatiles to the exhaust opening.
Abstract:
The bulk polymerization of monomers which produce polymer insoluble in the monomers, in which the polymerization is carried out in an autoclave mounted on a horizontal axis and provided with stirring means formed of at least two half-frames arranged symmetrically of the axis of the autoclave and fixed at each end to a rotatable stub shaft axially mounted in the autoclave, each half-frame having a peripheral member serving as a blade which, on rotation of the half-frames, passes in close proximity to the interior surface of the autoclave, and bracing means interconnecting the peripheral members of the half-frames.
Abstract:
A rotary agitator for use in a long cylindrical container, which may for example, be a chemical processing or reaction chamber. The agitator has two bearing members which cooperate with bearings in the container to support the agitator in the container. A plurality of helical blades are connected directly to each of the bearing members. A number of lattice rods are connected between the blades and the bearing members, and between the blades themselves. The bearings, blades and rods may be hollow and may define flow paths for cooling fluid.
Abstract:
A dynamic mixer, useful for mixing components of viscous compounds, in particular for components of dental impression compounds, and use thereof, the mixer having a mixing tube that contains a drivable rotor and that has on one end an end wall having at least two inlet openings for components, and at the other end an outlet opening for the mixture thereof. The rotor has a rotor disk having at least one entraining element that faces the end wall, and at least one rotor disk opening for the components to pass through to the side of the rotor disk that is remote from the end wall. At least one mixing element is arranged on the rotor hub between the rotor disk and the outlet opening. At least one projecting pin is arranged on the end wall toward the rotor disk, and the at least one entraining element has at least one recess for the at least one pin.
Abstract:
An application device for materials, in particular adhesives, including at least one cartridge receiving device for receiving a replaceable cartridge which contains a material and has a material outlet opening; a rotary device for metering or mixing the material, rotary device having a first engagement element; a drive device for driving the rotary device, the drive device having a rod which is mounted in a rotatable and axially movable manner and has a second engagement element at the end face; and a gearing unit for driving the rod in order to bring the first and the second engagement element into engagement with each other.
