  • Patent number: 7111535
    Abstract: A microtome includes a knife holding device for a cutting element (16) and a specimen holding device (12). Associated with the specimen holding device (12) for 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 a feed movement. A sender (20) is associated with the first drive device (18) and is connected with an electronic control means (26). A first operating element (28) controlling the first drive device (18) has a standard mode, in which the cutting movement of the specimen holding device is controlled by rotation of the first operating element (28), and a second mode, in which a continuous cutting function is activated by pressing the first operating element (28). A second operating element (44) controlling the second drive device (38) also has corresponding rotary and pressing modes.

  • Patent number: 7066067
    Abstract: A microtome, in particular a rotational microtome, comprising a base frame (10) on which is provided a specimen holding device (32) for performing a vertical cutting movement. The microtome further has a knife holding device (12) for a cutting element (24) which is formed by a cutting knife (26) or a cutting blade combined with a blade holder. A considerable cost saving and a substantially enhanced level of torsional stiffness and stability when the cutting forces take effect is achieved in that in the microtome the knife holding device (12) has two side plate portions (14) which project forwardly from the lower end portion (16) of the base frame (10).

    Abstract: 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.
