  • Patent number: 5161446
    Abstract: In order that biological and histological sections may be produced without the risk of injury and at an expenditure acceptable for hobby and instructional purposes, a specimen arm whose distal end carries a specimen holder is supported on the base plate of the microtome. The specimen arm is attached to the base by a spindle which is mounted on the base plate such that it can be displaced in the direction of the cutting knife. An adjusting member is provided for adjusting the position of displacement of the spindle. Uniform section thicknesses are facilitated by a locking ball received in the adjusting member. A clamp is provided on the base plate for holding commercially available cutting blades at the required clearance angle of the cutting edge. Movement of the specimen arm can be brought about by means of a handle or a crank. When the specimen arm is tilted away, unintentional contact with the cutting edge is prevented by a movable blade guard.

  • Patent number: 5141064
    Abstract: A damping mechanism is disclosed for use with a displacement measuring device, such as a load cell of the type immersed in a motion damping liquid contained within a housing. The mechanism includes a shear plate adjustably supported by the housing within the damping liquid for movement towards and away from a facing surface of the load cell, which is supported for movement within a plane disposed parallel to the shear plate, for purposes of controlling the thickness of the layer of damping liquid disposed there-between. The thickness of the layer determines the damping characteristics of the mechanism.
