  • Patent number: 7600457
    Abstract: An apparatus and method for producing tissue slides is disclosed. The apparatus includes a holding assembly for manipulating the sample block, a blade assembly for preparing a thin section from the sample block, and a transfer roller mechanism for transferring the thin section to a receiving medium. The apparatus further includes a controller that may track the sample block and thin section. The method includes the steps of first locating a sample embedded within a support medium, which may be paraffin or a similar medium. Next, the embedded sample is oriented in such a way that its working surface is presented. This orientation may entail determining the orientation of the embedded sample with respect to the blade that will produce the largest cross-sectional area. Next, a slice of the sample from said embedded sample is removed and subsequently transferred to a suitable receiving medium, which may include a microscope slide.

  • Patent number: 4883542
    Abstract: The disclosure relates to a method and apparatus for cleaning container bodies. The containers are moved through a station where they are subjected to a neutralized atmosphere created by directing ionized atmosphere over the container bodies as they move through the station. The bodies are also subjected to wiping action of brushes to remove particulate material therefrom. A vacuum system is employed to completely remove the particulate material from the atmosphere.
