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: A horizontally oriented three sided frame is adapted to hold a round hay bale. An endless chain driven conveyor in the floor of the frame causes the round bale to rotate about a longitudinal axis while simultaneously urging a portion of the perimeter of the bale against a sickle bar cutter arrayed just above the floor on one side of the frame. The cutter chops the hay bale into manageable portions for feeding to livestock. The sickle bar cutter includes a conventional reciprocating cutter bar with triangularly shaped cutting teeth arranged continuously along the bar. A specially designed blade guide allows the entire cutting surfaces of the teeth to extend past the blade guide as they reciprocate. This insures that the hay bale is fed rapidly into the reciprocating teeth since no blade guide teeth enter the cutting gaps between the cutting teeth as they reciprocate and thus do not interfere with the advancement of the hay bale into cutter.

Abstract: A device for tearing-up and stoking straw into a burner unit. A reciprocating slide is provided under a magazine shaft for straw bales, the slide having mutually staggered teeth on its upper side in a forward part of the slide and elongated fins extending in the direction of movement of the slide in a rear part. The part closest to the stoking channel constitutes a piston means for the conveyance and compression of comminuted straw. The straw is torn-up during the initial advance movement of the slide towards the channel because the teeth are in engagement with the bottom of the lowermost bale, whereas the bale is upheld by the teeth and the fins during the return movement of the slide. The piston means ensures that the shredded straw is pushed into a stoking channel for the combustion chamber of a boiler. Very compressed straw bales are thereby very uniformly comminuted and compressed before being fed into a burner unit.

Abstract: Soft-ice mixture, consisting of water or milk and commercially available powder, is frozen solid in a cylindrical container, then presented to a machine whereby the container is pressurized and which has an agitator that engages the surface of the solid to exert force along a narrow zone, whereby the material is locally melted. The momentarily melted material is immediately whipped by the agitator, before it refreezes. The agitator rotates at high speed (2,000 rpm) but advances into the material very slowly. For such action the agitator shaft is surrounded by an outer driver confined to rotation in one direction, with which the shaft has a splined connection, and the shaft in turn surrounds a threaded inner driver, with which the shaft has a threaded connection. For driving the agitator downward the inner driver is rotated in said direction, but slower than the outer driver; for driving it upward the inner driver is also rotated in said direction, but faster than the outer driver.

Abstract: Manufactured goods such as cast components to which molding sand is still adhering, are treated in a vibratory conveyor chute for cleaning and cooling the goods. As the goods travel down the chute they are exposed to force components extending perpendicularly and across to the travel direction along the length of the chute. These force components impose on the goods a revolving motion along a helical path. This revolving motion may be improved or intensified by directing the resulting force components (R, R') of the force causing the revolving motion to extend at a spacing from a so-called "center of gravity line" (S, S') defining or interconnecting the center of gravity points along the length of the vibratory chute system. This spacing causes a distribution of the goods (11) in the chute such that the goods (11) have a slanted surface (10) in the chute (1). Thus, the vertical acceleration values (k.sub.v) are larger at the upper return zone 26 than they are at the lower return zone 27.
