Abstract: This disclosure includes entry and delivery clamps arranged on opposite sides of a multiplaten press for clamping belting in order to apply a tension to the belting prior to pressing. The tension is applied by moving the entry clamp in a direction away from the press. The belting is fed over support rollers on opposite sides of the press which receive the belting from different openings of the press. These rollers are caused to move before the press is closed to maintain the belting away from the hot platens of the press, then moved in concert with and in the direction of the platens during pressing and then, if required, they may be moved independent of the platens when the press has been opened after pressing to effect a stripping of the belting from the platens.

Abstract: An endless belt conveyor extends from below a rolling part formed of each roller clearance of a series of linearly arranged rolling roller devices. The conveyor is either fixed or elevatably adjustable. Each roller device is driven by one common motor to the rolling part of the next rolling roller device so that a wheat flour band advancing while being rolled, in series, by each rolling roller device may be automatically introduced into the next rolling roller device. The band may be supported in case it becomes loose while being rolled and may be automatically introduced into the rolling part of the next rolling roller device even if it breaks.

Abstract: Process and apparatus for forming essentially spherical solid pellets directly from a melt, and particularly solid metal pellets such as iron and lead. The melt from a column of a preset height is directed through one or more orifices in a way to form a jet which experiences an upwardly directed trajectory path and which under the influence of vibratory action breaks up to form pellets of a predetermined diameter. Adjustments of the column height and/or vibration frequency are used to control pellet diameter. The pellets may be formed and solidified in a controlled atmosphere; and in the case of iron pellets, the carbon content of the pellets may be adjusted, to attain a desired degree of hardness, either before or after pellet formation. Iron pellets thus formed are particularly suitable as substitutes for lead pellets in ammunition.

Abstract: Organic waste materials are mixed and batches are separately brought into the form of a coherent substantially homogeneous pulp with a moisture content between 50 and 55% by weight, by heating with exhaust gases, drying in an oven, admixing dry material, and spraying dry material with liquid manure recuperated from the waste materials. The pulp is chopped and immediately thereafter extruded to form frangible strands, sections of which are allowed to break off, without cutting, and to further break by dropping onto a conveyor. Breakage into pellets is completed, without the use of a conventional pelletizing drum involving compression of the pellets, in a vibrated fluidized bed where the pellets are superficially dried to a non-tacky state, drying being completed in further non-vibrated fluidized beds.

The bundles are then removed from the bundling station ready for shipment or storage.

Abstract: A calender especially suitable for use with rubber and plastic material. One of two opposed rolls is movable toward and away from the other through direct action of long-stroke fluid actuators that move the bearing boxes on opposite ends of the movable roll. Roll spacing is directly sensed by position-sensitive transducers acting between opposed bearing boxes and responsive to the relative roll positions. The transducers signal changes and initiate correction to retain roll spacing at a set distance. The fluid actuators are controlled to separate the rolls upon power failure and to prevent roll contact in the event work product is not between the rolls.
