A microtome comprising a knife holding device for a cutting element (16) and comprising a specimen holding device (12) for a specimen which is to be cut thin is described. Associated with the specimen holding device (12) for performing a cutting movement is a first drive device (18) and associated with the specimen holding device (12) or the knife holding device is a second drive device (38) for performing a feed movement. A sender (20) is associated with the first drive device (18). The sender (20) is connected with an electronic control means (28). Control of the first drive device (18) is effected by means of a first operating element (28). Control of the second drive device (38) is effected by means of a second operating element (44). To achieve an excellent degree of operating comfort for the microtome the first operating element (28) has two control modes, namely a standard mode and a second mode. In the standard mode the cutting movement of the specimen holding device is controlled by rotation of the first operating element (28). In the second mode a continuous cutting function is activated by pressing the first operating element (28). Corresponding to the first operating element (28) the second operating element (44) has two control modes, namely a rotary mode and a pressing mode.

In a resonating assembly, a beam having a pickup thereon is positioned proximate to a magnet which passes across the pick up at a predetermined frequency. The passage of the magnet across the pick up establishes an alternating magnetic field that in turn causes the beam and pick up to vibrate. A blade is mounted on the beam and vibrates therewith so that when the blade is brought into engagement with a layer of sheet type work material the vibratory amplitude of the blade causes the blade to cut through the material as it is moved in engagement therewith.

In a preferred embodiment, a sealing tape dispenser, includes a retracting tape guide which is mechanically linked to an access cover so as to be automatically retracted upon cover opening to allow larger tape rolls to be loaded and to enhance unobstructed access to the machine. In a second preferred embodiment, a sealing tape dispenser, includes a cutting blade lift and interlock mechanism as to assist in clearing tape jams by mechanically lifting the cutting blade to a raised position whereby unobstructed access is gained to the tape path and an interlock is disabled so as to prevent further tape dispenser operations while the cutting blade is in a raised position.

A rotary knife incorporates the use of an electronically controlled, active damping system to control vibrations of knife cylinders. The system preferably uses pairs of electromagnetic actuators to provide opposing pulling forces on a ferromagnetic portion of a lever arm that is mechanically coupled to the stationary support shaft for the knife cylinder. Vibration sensors, preferably accelerometers, are used to monitor vibrations of the respective knife cylinders. A digital signal processor implementing a state space control system controls the electromagnetic actuators to actively cancel vibration energy in the knife cylinders.

A rotary knife incorporates the use of an electronically controlled, tuned mass active damping system to control vibrations of the knife cylinder. The system preferably uses one or more electromagnetic actuators to provide force on a tuned mass which is mechanically coupled to the knife cylinder. Vibration sensors, preferably accelerometers, are used to monitor vibrations of the respective knife cylinders and tuned masses. A digital signal processor implementing a state space control system controls the electromagnetic actuators to remove vibration energy from the system. An active damping system in accordance with the invention is more effective in removing vibration energy than passive systems, especially in heavy-duty applications.

A magnetic device (22, 222 or 322) for scoring glass (150) and a method for using the device to score glass. The system (100) for use with the device includes a scoring board (12), a scoring guide (18 or 218) and the device. The scoring guide has a smooth, flat outer surface (18E or 218C) and is constructed of either a magnetic or magnetically attractable material. The device includes a body (24 or 325) and a blade unit (26). The body has a smooth flat end and is preferably magnetic. Alternately, the flat end is constructed of a magnetically attractable material. To score glass, the glass sheet is placed on the scoring board and the guide is mounted on the board over the glass. The guide is mounted adjacent and parallel to the line to be scored on the glass. The flat smooth end of the device is mounted on the flat smooth outer surface of the guide so that the blade (26B) of the blade unit is aligned with the line to be scored. The user then exerts a downward pressure on the device and moves the device along the guide.
摘要:
Dimpling of a workpiece by rebounding of a magnetic repulsion punch mechanism, when operated at high punching rates, is avoided by application of a damping pulse at a point at or subsequent to a mid-point of a return stroke of the punch from the workpiece and preferably within the last 10% of the return stroke. This damping pulse is preferably a fraction of the pulse width and of approximately the same amplitude as a driving pulse applying kinetic energy to the punch for causing punching of the workpiece. At high punching rates the kinetic energy of the return portion of a punching stroke is substantially determined by elastic rebounding of the punch from a guide bushing. The removal of kinetic energy during the return portion of the stroke allows the return of the punch to a position close to a rest position during a very short interval with small overshoot under control of mechanical damping. Since dynamic damping may be substituted for much of the mechanical damping in the punching arrangement, high quality punching may be accomplished at much increased punching rates. A preferred form of monitoring punch position employs RF reflected inductance and may be used to form a time expanded image of punch movement.
