Abstract: A rotary microtome (1) for producing thin sections for histology is used for specimens (6) of different sizes. To maintain optimized cutting conditions, an adaptation to different specimen sizes is required without incurring disadvantages in terms of operation. An adjustment possibility is provided for the length of the vertical cutting movement (10). However, the moment that is generated by the vertical carriage (7) and that acts on the drive shaft (12) then changes. To maintain balanced moments of the drive movement, the counterweight has to be accordingly adapted by an adjustment weight (31). For this purpose, means are provided which, in an ergonomic and effective manner, permit the adjustment of the cutting stroke and also the necessary adaptation of the counterweights in one operation step.

Abstract: Novel modifications to a standard Pro-lok Blue Punch manual punch press machine have been developed which permit the modified machine to accurately and consistently cut Sargent brand L and R series keys to code. Modifications to the same machine are presented such that both Sargent L and R series keys may be cut to code on the same Pro-lok Blue Punch manual punch press machine. Primary features of the modifications are (1) moving the indexing stops from the lower jaw to the upward facing surface of the die and (2) providing two indexing stops on the die such that each stop is laterally positioned on opposite sides of the punch from the other.

Abstract: A microtome having a rotatable platform and a fixedly mounted cutting blade which is disposed perpendicularly to the axis of a shaft about which the platform rotates. With each rotation, it carries the specimen holder beneath the blade. The height of the cutting edge of the blade relative to a specimen mounted atop the holder determines the thickness of any section cut therefrom. After each cut, the holder can be automatically raised in height by a predetermined increment to allow another section of the same thickness to be cut. Mechanisms are also provided which eliminate play in both the radial and axial directions between a cylindrical housing supporting the platform and the shaft, so that the microtome can be used to make extremely precise cuts of specimens.

Abstract: A device for controlling the drive and forward feed of a microtome, particularly an ultramicrotome, includes a driving motor for moving a specimen or knife and a servomotor for generating a forward feed of the specimen towards an edge of the knife or vice versa. A high travelling speed of the specimen needed for rapid initial cutting is coupled to a high rate of forward feed. One single switching operation is performed, for instance, by a snap-engaging step switch via relay switches. The driving motor and the servomotor can be simultaneously switched over to pairs of values which correspond to subsequent rough cutting and ultra-thin cutting. Individual values for cutting speed and forward feed are separately preselected, readjusted, and read from a display. Selected program stages are indicated by signals.

Abstract: A key-cutting device includes a holder which holds the key blank. The holder is movable between initial and cutting positions. When the holder is in a cutting position, a cutter is moved to cut one or more notches in the key blank. An actuator is connected with the base to move the holder from the initial position to the cutting position. The actuator includes an improved saddle assembly in which a leaf spring is connected with a force transmitting member. A body of polymeric material is disposed between the leaf spring and the force transmitting member. Force is applied to a free end of the leaf spring to move the holder from the initial position to the cutting position. Upon continued operation of the actuator, the leaf spring is deflected about a fulcrum which is at least partially formed by the body of polymeric material. As the leaf spring is deflected, the body of polymeric material is resiliently compressed.

The frame structure carries first and second abutments arranged at the respective end portions of the path of movement of the switch element which oscillates with the object holding member. The switch element is thus displaceable by co-operation with the first and second abutments between first and second positions respectively; when the switch element is in its first position the object holding member is in a position in which it is set back from the cutting plane while when the switch element is in its second position the object holding member is in a position of being advanced into the cutting plane for an object-cutting operation.
