Abstract: A rip fence for a table saw includes a frame having a front portion and a rear portion. A front clamping lever is pivotably supported in the front portion of the frame for movement between a clamped and an unclamped position. A handle is pivotably supported in the front portion of the frame for movement between a locked and an unlocked position. The handle includes a lever portion that engages the front clamping lever and moves the front clamping lever from the unclamped to the clamped position when the handle is moved from the unlocked position toward the locked position. A rear clamping lever is attached to the rear portion of the frame and movable between a clamped and unclamped position. When the front clamping lever is moved to clamped position by the lever portion of the handle, continued movement of the handle to locked position results in the handle pulling the rear clamping lever from the unclamped to the clamped position.

Abstract: During the parallel splitting up of workpiece panels, in particular, consisting of laminated, compressed wood, it is usually not possible to prevent one of the two panel sections resulting after completion of the last separating cut, more particularly, that which was clamped in the feeding device, from warping on account of material tensions, thereby rendering it useless. In order to avoid this, it is proposed that the trimmed edge of the last remaining panel section facing away from the cutting plane be released prior to the final feeding procedure to be carried out, that it be clamped again immediately thereafter, that a further trimming cut be made on the panel section, and that this panel section then be fixed following the final feeding procedure and trimmed anew. In this process, the last resulting panel section is relieved of tension before being finally trimmed along its two longitudinal sides. This ensures that the trimmed edges subsequently produced thereon are exactly parallel to one another.

Abstract: A foodstuff such as a sausage is sliced in a predetermined slicing direction into a succession of slices each having a respective width measured parallel to the slice direction. This succession of slices is then deposited on a support in a plurality of rows with the slices in each row offset from one another by a predetermined first distance and the rows offset from each other by a predetermined second distance. The width of the slices is continuously measured as they are cut and at least one of the distances is automatically varied in dependence on the measured width to produce a uniformly overlapping array of slices. In addition the machine can calculate the weight of a given slice by combining the width with the slice thickness and the slice density, and this weight can be divided into a desired weight to determine how many slices at the predetermined size are needed to make up the desired weight. A signal can indicate then when this weight is reached.

Abstract: A microtome, in particular an ultramicrotome, has a drive-control system by which the movement of the specimen arm, relative to the knife, is subdivided into a comparatively slow cutting movement and a more rapid return movement. The drive-control system gradually decelerates the specimen arm at the transition, from the comparatively rapid return movement to the slower cutting movement, so that a jerk, which would generate mechanical vibrations in the drive system, is avoided and the specimen arm is smoothly decelerated from the comparatively high speed to the lower speed.

A threaded spindle serves to advance the blade bracket and thus the blade. The blade is retracted from the specimen after each cutting process, independently of the advance of the blade slide. For this purpose, the blade holder is merely tilted slightly by being raised around an axis, which forms an acute angle with the cutting edge of the blade. The blade holder is raised by a lever arrangement, coupled through a shaft and a pivot bearing with the drive shaft of the specimen slide.

Abstract: A slicing and measuring apparatus for sausage and the like has a table which supports the foodstuff to be sliced and is displaceable back and forth adjacent a blade which is continuously rotated by an electric motor.

Thereafter this volume is mulitplied by the density of the foodstuff to determine the weight of the slice and the weight of successive slices can be added to determine the total weight sliced.
