Title: Apparatus and method for making free standing diamond
Inventor: FELLBAUM RANDY D
IPC: C30B29/04
Filed: 1996-01-24
Abstract: A mandrel for use in a diamond deposition process has surfaces with different diamond adhesion properties.  According to one embodiment, a mandrel is provided and has first and second surfaces on which a diamond film is deposited, with the second surface forming a perimeter around the first surface.  The first surface of the mandrel has a first diamond bonding strength which is less than a second diamond bonding strength of the second surface.   In an embodiment for forming a cup-shaped diamond film, the mandrel is a titanium nitride (TiN) coated molybdenum (Mo) substrate having a stepped solid cylindrical shape with a central mesa having a side wall or flank.  The side wall is etched near the top surface of the mesa to expose a molybdenum band and to form a second surface which bounds the TiN first surface.  When the molybdenum band loses efficiency as a result of diamond particles remaining in the molybdenum band after a diamond deposition procedure, a second strip of the TiN coating adjacent to the first strip may be etched or machined to expose a second band of molybdenum.  Other embodiments of the invention include machining the molybdenum band on the mesa top surface, machining a stepped molybdenum band, using a separate and detachable molybdenum foil or wire applied to grooves in the mandrel, and forming radial lines or patches on the surface of the mandrel.

Inventor: HOLLANDS KEITH G M
IPC: A61F5/448
Filed: 1996-04-15
Abstract: An ostomy coupling has first and second coupling members. These can be held together by a springy flexible split locking ring. A plurality of tabs, arranged, e.g. symetrically, on the limbs of the locking ring, can be withdrawn generally radially outwardly by movement of the locking ring to permit separation of the two coupling members. The movement of the locking ring which causes withdrawal of the tabs may be a vertically upward movement of the ring, or a vertically downward movement. The movement of the locking ring which causes withdrawal of the tabs alternatively may be a deformation of the ring in opposed horizontal directions. Preferably, however, the movement of the locking ring which causes a withdrawal of the tabs is a rotational movement relative to the second coupling member.

IPC: B01D35/06
Filed: 1996-12-30
Abstract: A filter element has an internal coil spring which is magnetized to remove magnetizable particles from a stream of lubricating oil prior to the oil passingthrough an annular filter media. The annular filter media is part of a cylindrical filter element which includes an end cap that closes one end of the filter element and an internal sleeve which defines a hollow core.
