Abstract: A system for inspecting first and second surfaces of a cutting member, such as a tooth of a carbide tooth circular saw blade, includes a support for carrying the cutting member, the cutting member being movable relative to the support to position the surfaces to be inspected within an inspection zone. First and second video cameras mounted on the apparatus relative to the inspection zone provide output signals representative of the images of the first and second surfaces, respectively. A computer responsive to the output signals generated by the first and second video cameras analyzes the output signals and calculates selected attributes of the surfaces presented for inspection. A frame grabber captures video images of the surfaces. A first video monitor coupled to the computer displays images of the surfaces being inspected while a second video monitor coupled to the computer displays graphical data relating to selected geometrical attributes of the surfaces.

Abstract: An apparatus for blood sample treatment involves lysis, filtration and culture, the apparatus being in the form of a unitary culture chamber assembly consisting of an upper chamber for receiving a blood sample, this upper chamber receiving lysing solution squeezed from an attached bag which is subsequently detached. The upper chamber is located over and is in telescopic engagement with a lower chamber, and then vacuum is applied to the lower chamber to accomplish filtration. The lower chamber is then detached and discarded. The upper chamber is sealed and an attached bag of culture medium is squeezed to introduce the medium into the upper chamber from the bag. This second bag is detached, leaving the upper chamber as a complete blood culture system.

Abstract: An apparatus for blood sample treatment involves lysis, filtration and culture, the apparatus being in the form of a unitary culture chamber assembly consisting of an upper chamber for receiving a blood sample, this upper chamber receiving lysing solution squeezed from an attached bag which is subsequently detached. The upper chamber is located over and is in telescopic engagement with a lower chamber having a pointed hollow needle engageable through a rubber diaphragm in the bottom of the upper chamber when the upper chamber is pressed down. This is done after complete blood lysis, and then vacuum is applied to the lower chamber to accomplish filtration. The lower chamber is then detached and discarded. The diaphragm is sealingly covered and an attached bag of culture medium is squeezed to introduce the medium into the upper chamber from the bag. This second bag is detached, leaving the upper chamber as a complete blood culture system.
