The movable blade is supported by the bell cranks which hold the sharp edge of the movable blade parallel to the sharp edge of the lower blade during the entire reciprocal path traversed from open to closed position and back to the open position. The lever is connected to links provides leverage to force the movable blade down into contact with the stationary blade.

Abstract: The invention relates to a microtome having a blade oscillating transverse to the direction of advancing the cut, for sections on soft tissue samples. The oscillation frequency of the blade is controlled variably by the rotational speed of an electric motor. At the same time, the oscillation amplitude of the blade is also adjustable variably with the aid of an adjustable eccentric or a displacement device. This makes individual adjustment to the consistency of the tissue sample possible, which leads to improved quality of the microtome sections, in particular to a reduction in the waviness of the sections. This makes significantly thinner microtome sections possible, with corresponding advantages during microscopy.

The blades successively perform a movement of penetration into the interior of the container, a movement of angular pivoting along an arc of a circle corresponding to the height of the container, and a movement of withdrawal from the container, so as to assure by the combination of these movements the slicing of all of the layers of food.

Abstract: The blade having a convex or concave edge and a workpiece engaged by the blade are relatively displaced by an oscillating parallelogrammatic linkage so that an arcuate contour is cut in the workpiece. The oscillating radius of the parallelogrammatic linkage and the radii of the curvature of the blade and the cut contour are dimensioned so that the contact between the cutting edge of the blade and the workpiece is a quasi-point contact. This allows rapid cutting for thin pressure-sensitive materials.

Abstract: The invention pertains to a saw, in particular to a jig saw or scroll saw, with a saw blade which is driven by a force acting on a parallelogram of rods. A saw blade is attached to a connecting shank which joins two longitudinal side arms. The two longitudinal side arms are designed to move in their longitudinal direction. On at least one of the two longitudinal side arms a guide element in the form of, for example, a turning roller, is positively guided against a stationary guide surface which is at an angle, preferablye an acute angle, to the connecting shank. As a result of this positive guidance, the backward movement of the saw blade from the cut edge during the return stroke is reduced to a desired value. Thus a jig saw of small size, but with a large stroke, can be realized in which the saw blade is guided parallel to the cut edge at all times but is moved back by a small amount from the cut edge during the return stroke.

Abstract: A wire saw has a wire wound a number of turns around a plurality of multigrooved rollers to form rows of the wire between the rollers which cut a workpiece. By reversibly rotating the multigrooved rollers, the wire is moved gradually from a wire feeding side to wire recovery side of the saw while undergoing a reciprocating motion between the multigrooved rollers. In addition, the multigrooved rollers are rotated around a fixed axis to swing the wire in a manner that provides contact with the workpiece which is quite close to point contact. Thus, a concentrated load is applied to the workpiece fully utilizing the permissible tension on the wire, and thus accelerating the cutting speed and raising the cutting accuracy.

Abstract: A vertically disposed nozzle continuously extrudes a descending column or bar of semi-frozen confection which passes through a ring gear. A cutoff wire is anchored to the ring gear and to a second, laterally adjacent ring gear. Slip rings adjacent the ring gears electrically energize and heat the cutoff wire. Both gears are driven in the same direction, and the anchor points are located to maintain uniform interspacing and thus keep the cutoff wire linear to transversely slice the moving product bar. The gears and cutoff wire are adjustably mounted to be unitarily tilted from the horizontal so that the product bar is repetitively severed along parallel lines to produce slices each having uniform thickness, with the severance lines perpendicular to the side surfaces of the product bar. A wiper is arranged to clean the cutoff wire after each cutting stroke so that the product will not accumulate and burn onto the cutoff wire.
