Abstract: A device 10 for crushing medicaments originally formed in pill of tablet contour into a fine powder. An impact device 140 moves from a first energy stored position latched thereagainst spring pressure awaiting tripping of the latch or cam 190 by the pill which has been ensconced in a container embodied as an envelope 260. The envelope 260 is placed in a slot 84 and oriented to trigger a switch 234 which releases from a captive position the hammer 142. The hammer 142 advances linearly impacting against an anvil 89 upon which the envelope 260 and the enclosed pill awaits. The explosive force of the hammer 142 creates a powder substance because of the explosive nature of the hammer's 142 contact against the anvil 89. While the hammer 142 is being withdrawn under motor drive 212, the envelope 260 may be removed for access to the interior contents for subsequent dispensation.

Abstract: Brittle material (1) is ground batchwise as a bed of particles by compression between non-yielding hard surfaces at a pressure of at least 50 MPa. In order to reduce the energy requirement and machine expenditure needed for fine, superfine and microfine comminution, the bed of particles is subjected to repeated stressing by pistons (4) in different directions and at least in part successively. The stressing preferably is accomplished by groups of two opposed pistons (4), which are offset at an angle with respect to each other and which are rendered active one after the other. The stressing is repeated in another plane of the grinding chamber. Wet grinding is carried out in a closed grinding chamber from which the liquid expelled from the voids between the particles being ground can drain through at least one aperture of narrow cross section.

Abstract: The present invention discloses a device for recycling a tube such as a core having housing which has an upper side, a lower side, and a first side. Attached to the upper side is an input chute. The input chute receives the core. The bottom end of the core is fed into a traveling horizontal blade as well as a splitter blade. The travelling horizontal blade makes a horizontal cut proximate to the lower end of the core whereas the splitter blade makes a cut proximate to the lower or distal end of the core in a vertical direction. The same piston that pushes the splitter blade and traveling blade into the core then pushes the core into a stationary blade which makes another horizontal cut and separates a piece from the core which then drops into a storage area. The same piston which pushes the splitter blade and traveling blade can then push the pieces in the storage area toward a discharge chute.

Abstract: A crusher is disclosed, which comprises a stationary blade and a movable blade, the movable blade being capable of being rotated by a driver, e.g., an oil hydraulic cylinder, toward the stationary blade to clamp an object to be crushed between the stationary and movable blades and crush the object. The movable blade has tip projections projecting outwardly so that an object projecting from a road or ground surface can be clamped at its stem between the tip projections of the movable blade and the tip of the stationary blade. The object thus can be crushed from the stem. The stationary blade has a hollow frame to reduce the weight of the crusher.

Abstract: A rock crusher includes a dual cam shaft drive mechanism for imparting substantially linear motion to a movable jaw between a pair of fixed jaws. A driven cam shaft coupled to the movable jaw cooperates with another cam shaft also coupled to the jaw to impart this motion to the jaw. In one embodiment, the maximum eccentricity of the driven cam shaft is less than the maximum eccentricity of the other cam shaft so that the other cam shaft oscillates and imparts the desired motion to the movable jaw. In another embodiment, the cam shafts have the same maximum eccentricity and are synchronized to move together, such as by gears, during crushing.
