Apparatus And Method For Automatically Producing Tissue Slides
View pageUS Patent:
6387653, May 14, 2002
Filed:
Apr 9, 1999
Appl. No.:
09/289181
Inventors:
John Voneiff - Baltimore MD
Jay Frederick Gibson - Pasadena MD
Jay Frederick Gibson - Pasadena MD
Assignee:
Culterra, LLC - Baltimore MD
International Classification:
G01N 130
US Classification:
435 4052, 435 405
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.

Method And Apparatus For Cleaning Containers
View pageUS Patent:
48835420, Nov 28, 1989
Filed:
Dec 22, 1987
Appl. No.:
7/136323
Inventors:
John Voneiff - Baltimore MD
International Classification:
B08B 102
US Classification:
134 21
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.
