Abstract: A slicing machine has a housing, a rotatable blade on the housing having an edge defining a blade plane, and an input table on the housing displaceable parallel to the plane past the blade edge and having a holder adapted to hold a foodstuff to be sliced by the blade. The foodstuff is movable from a starting position by the table and holder toward the blade to slice the foodstuff. An abutment plate on the housing is displaceable between a shield position lying generally on the blade plane and a retracted position offset away from the table from the blade plane. An actuator connected between the housing and the plate sets the plate in its positions. A sensor generates an output when the foodstuff is moved out of the starting position. A control unit connected between the sensor and the actuator displaces the plate out of the shield position when the output is generated.

Abstract: A microtome with a drive device is described, which has a shaft and a handwheel, arranged thereupon, with a grip. For locking the drive device, an electromagnet is firmly arranged on the housing frame of the microtome. The latter is in effective connection with an indexing ring, axially displaceable on the shaft. A control device, which is electrically connected to the electromagnet and to a sensor, controls the electromagnet in response to a signal of the sensor. The sensor triggers the signal by the position of an indexing ring arranged axially displaceably on the shaft. The said indexing ring is movable in frictional connection with a pin arranged in the grip and axially displaceable by means of a lever. The lever is actuated by seizing of the grip and the locking of the drive device is cancelled.

Abstract: A sawmill carriage is provided with crosswise disposed guideways along which knee members travel for advancement of a log toward a saw plane. Linear actuators for each knee member are embodied in parallel hydraulic cylinders above and below a slide also on the guideway to reduce overall carriage width. A first linear actuator serves to position the slide while the remaining linear actuator is carried by the slide and has a piston rod end coupled to the knee member. The linear actuators function both in singular and in simultaneous modes to provide desired knee member movement and speed. The linear actuators are of the type providing a feedback signal which is processed by a controller for programmed operation of the actuators. Rail components of the guideways support the knee member and the slide on separate portions of the rails.

Abstract: A microtome has a frame structure in which an object holding member for holding an object to be thinly cut is movable with an oscillating movement by a drive device. The object holding member has a cutting thickness feed member and an object return member, the latter including a switch element disposed on the object holding member for oscillating movement therewith. 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.

Abstract: A band-saw-cutting system for cutting sections from a work in a substantially continuous, automated manner. The system includes a work carrier adapted to support one or more pieces of work and to be reciprocated to carry the work from a home position to a forward position in a cutting stroke to cut the work and back to the home position in a return stroke. The system includes blade-moving means for automatically moving the blade out of the cutting plane of the blade during each return stroke such that the work will not contact and rub against the blade during the return stroke, and for moving the blade back into the cutting plane prior to the initiation of the next cutting stroke. The system further includes means for automatically moving the work transversely against an adjustable fence to position the work relative to the cutting plane to cut desired thicknesses from the work during each cutting stroke.

Abstract: Disclosed is a traversing microtome having a base (10) and a movable carriage (13). A blade holder (12) with a blade (16) is mounted on the base (10), and an object holder (14) is mounted on the carriage (13). To carry out the cutting process, the carriage (13), together with the object holder (14) and the object (15), is moved against the stationary blade (16). Between the guide rails (18,18') of the base (10) and the carriage (13) a bearing gap (30) with a width of a few microns is created by means of air bearing elements (21,21'), and consequently only a minimal force is required to move the slide (13). Between the air bearing elements (21,21'), magnets (22,22') are arranged so that their attracting forces act against the air pressure of the air bearing elements. In this manner, the force needed to arrest the motion of the carriage (13) at any given location of the guide rails (18,18') is extremely low. The carriage (13) cannot be moved when the supply of air is interrupted.

Abstract: An apparatus for selective attachment to a rotary microtome in order to permit separation of the specimen from a cutting knife during the return stroke of the specimen. A small frame is adapted to fit within the conventional specimen holder or chuck of the microtome; and the frame carries a solenoid with a movable core. Attached to the forward end of the movable core is an auxiliary specimen holder; attached to the other end of the core is a plate against which a compression spring constantly presses. The preferred power supply for the solenoid is a filtered 30 volt DC power supply. The solenoid is energized only during the downward, cutting stroke of the microtome, and it is de-energized before the arm starts its return stroke. The spring urges the specimen holder away from the knife when the solenoid is de-energized. The apparatus may be readily installed on any conventional rotary microtome with minimal skilled labor; and it may be removed at will to restore the microtome to its original condition.
