Abstract: In order to reduce the conversion and cleaning effort between pre-dispersion by a dissolver (2) and fine dispersion by an agitating ball mill (3), it is proposed to combine both devices in a single container. The casing (31) of the agitating ball mill (3) is in the form of a toroidal annular channel with a central hole (34). The drive shaft (21) of the dissolver (2) runs through said central hole (34) in the agitating ball mill (3). Dispersion may take place in the dispersing device simultaneously or in succession. The agitating ball mill (3) is preferably lowered inside the container (1) along the common axis after a pre-determined time and caused to act on the substance to be dispersed (5).

Abstract: A forging or cold-pressing tool comprising an annular combination of nib pieces held in a case and having a regular polygonal die bore inside the nib pieces, each of the nib pieces having an approximately isosceles trapezoidal cross section. Opposite ends of each nib piece before assembly make an angle .alpha. smaller than an angle obtained by dividing 360.degree. by the number of nib pieces. When held in the case, the nib pieces are elastically deformed by a tightening force of the case, whereby the butting end faces of each pair of adjacent nib pieces are entirely pressed into contact with each other under a pressure increasing from portion to portion toward the die bore. A layer for giving improved resistance to seizure is formed over the surface of each nib piece.

Abstract: A process for economically handling spent mercury containing lamps in an efficient manner while protecting the environment against the release of mercury vapors into the atmosphere along with creation of non-toxic recyclable by-product materials therefrom is disclosed. The process includes the steps of: transporting a lamp crushing apparatus on a mobile vehicle to a site whereat mercury containing lamps are collected; loading the mercury containing lamps within a closed chamber defined by the lamp crushing apparatus; and, crushing the mercury containing lamps within the closed chamber while simultaneously extracting substantially all hazardous mercury vapors from the closed chamber during the crushing process to create non-toxic recyclable by-product materials from the lamps loaded into the closed chamber.

Abstract: A die set (24) for use with a stamping and forming machine (10) includes two opposed tooling plates (50, 52) arranged to undergo reciprocating motion with respect to a base plate (40) toward and away from a strip of material (30) that is fed along a feed path (38) between the two tooling plates (50, 52). Each tooling plate has a tool attachment surface (58, 60) facing inwardly toward the feed path (38) for the attachment of punch and die tooling assemblies (26, 28) for performing the stamping and forming operations on the strip of material. Each of the tooling plates (50, 52) includes four guide posts (82) that extend outwardly in a direction away from the feed path (38) so that the area (98) between the opposing tool attachment surfaces (58, 60) is maintained clear for the operation and maintenance of the punch and die tooling assemblies (26, 28).

Abstract: A bowl mill having a separator body, a grinding table and a plurality of grinding rolls for exerting grinding forces on material to be ground is provided with a plenum and a vane assembly for controlling the pressure conditions in the separator body. The vane assembly includes a plurality of vanes which rotate within the plenum to propel air from the plenum into an upper region of the separator body. This arrangement prevents or minimizes the penetration or migration of ground material into a lower region of the separator body of the bowl mill.

Abstract: A die tool monitor and analysis system identifies tooling changes and maintains tooling in an optimal position, thus maintaining the quality of the manufactured product within a desired tolerance band. A die tool force monitor and analysis system identifies changes in the operational conditions within a press. These identified changes are indicative of tooling changes and in conjunction with a thermal control system, facilitate the thermally induced expansion and contraction of a tooling support structure. The expansion and contraction of the supporting structure displaces the tooling member relative to its counterpart tooling member.

Abstract: The hammermill includes a housing, a working chamber defined by a polygonal screen, an inlet to the chamber, an outlet and a plurality of free-swinging hammers attached to a driven rotor. Support brackets extend the length of the housing and mount deflectors for eliminating tangential motion of materials being comminuted in the working chamber in the region of the deflectors. Side doors mount screen carriages for movement toward and away from the doors. In a closed position of the door, springs bias the screen carriages into engagement with wear-linings and the support brackets. The doors are pivotal away from the housing for access to the screens and the interior of the working chamber. A bottom screen carriage is movable toward and away from the chamber for access to the bottom screen sections.

Abstract: A reforming apparatus, and method of using the same, is provided for reforming the bottom of a container to increase the dome reversal pressure and improve the drop resistance of a beverage container. The invention is particularly apt for use in reforming a beverage container integrally formed from a thin metallic sheet. Such containers generally have an open top portion connected to an outer wall that is disposed about a container axis. The outer wall is connected to a bottom portion having an annular support surface, an outer surface for connecting the annular support surface and the outer wall, a recessed or dome surface, and an inner surface for connecting the annular support surface and the dome surface. The invention provides a container rotating device for spinning, supporting, and positioning a container during reformation. A container positioning assembly is included to accurately position the container relative to reforming tools (e.g., rollers).

Abstract: A channeled pulp rotor for use in a generally cylindrical or tub shaped pulper apparatus to make a slurry out of a mixture of solid and liquid materials for such things as paper making includes a rotor hub having at least one vane extending radially from a central axis of rotation of the rotor hub. The vane defines an impact surface between opposed top and bottom surfaces for impacting the solid materials upon rotation of the rotor and the impact surface defines a feed channel. The bottom surface defines a defibrating channel continuous with the feed channel so that materials flowing along or positioned in front of the rotating impact surface flow into the feed channel and continue from the feed channel to flow into the defibrating channel. In alternative embodiments, the feed channel and defibrating channels are eccentric to the axis of rotation of the rotor so that entries of the feed channel and defibrating channel are closer to the axis of rotation than exits of the channels.

Abstract: In two-roll machines for high-pressure disintegration of granular material, in which typically only one of the two rolls is motor driven, while the other roll is driven by means of friction via the granular material pressed in the roll gap, and thus operates as a drag roll, it is proposed to equip the drag roll with a separate, smaller drive mechanism including a separate smaller drive motor. This drive is thereby dimensioned in such a way that the startup of the drag roll is ensured and a drop in revolutions per minute of the drag roll is avoided. Alternatively, this separate drive is enlarged in such a way that it can transmit 10% to 40%, preferably 20%, of the total required drive power.

Abstract: A rotatable throat for a coal pulverizer is improved by creating a high pressure drop in the air ports which surround the throat. The lower portions of the air port nozzles are made of vanes and relatively thin sides, and shaped to provide air entrance areas from five to six times the release points of the nozzles.
