International Classification:

B23B 4700
B23C 528
B24B 4500

US Classification:

90 11A

Abstract:

Machine tools utilized in precision machine operations require tool support structures which exhibit minimal deflection, thermal expansion and vibration characteristics. The tool support structure of the present invention is a graphite fiber reinforced composite in which layers of the graphite fibers or yarn are disposed in a 0/90. degree. pattern and bonded together with an epoxy resin. The finished composite possesses a low coefficient of thermal expansion and a substantially greater elastic modulus, stiffness-to-weight ratio, and damping factor than a conventional steel tool support utilized in similar machining operations.

International Classification:

B01D 3502

US Classification:

210 94

Abstract:

A radiator cooling system filter assembly comprising a first housing member, a second housing member and a filter element. The first and second housing members are interconnectable with a snap fitting to form a filter element cavity into which the filter element is disposed during use. The first housing member includes a first cooling hose fitting at one end. The second housing member includes a second cooling hose fitting at one end. The first and second housing members are interconnectable in a manner such that when the first and second housing members are snapped together to form the filter element cavity, the filter element cavity provides a fluid pathway between the first and second cooling hose fitting. In addition, one of the first and second housing members is provided with a valve mechanism selectively operable by a user to provide a fluid pathway between the filter element cavity and the exterior of the cooling system.
