Patent CA-2286349-A1 (CA)
Title: Production of functional proteins: balance of shear stress and gravity
Inventor: HAMMOND TIMOTHY GRANT
IPC: A61K38/00
Filed: 1998-04-07
Abstract: The present invention provides a method for production of functional proteins including hormones by renal cells in a three dimensional co-culture process responsive to shear stress using a rotating wall vessel. Natural mixture of renal cells expresses the enzyme 1-a-hydroxylase which can be used to generate the active form of vitamin D:1,25-diOH vitamin D3. The fibroblast cultures and co-culture of renal cortical cells express the gene for erythropoietin and secrete erythropoietin into the culture supernatant. Other shear stress response genes are also modulated by shear stress, such as toxin receptors megalin and cubulin (gp280). Also provided is a method of treating in-need individual with the functional proteins produced in a three dimensional coculture process responsive to shear stress using a rotating wall vessel.

Patent CA-2300035-A1 (CA)
Inventor: PAGELS DONALD D SR
IPC: B23B41/02
Filed: 2000-03-03
Abstract: A line boring apparatus comprising a motorized spindle and tool support mounted on a support frame for motion along two axes perpendicular to a rotational spindle axis. The spindle is also supported for motion along the spindle axis relative to the tool support. A tool cradle is supported beneath the spindle on the support frame and stores boring bars of differing outside diameters equipped with support bushings having outside diameters equal to an inner diameter of the tool support. A CNC is programmed to actuate an axes drive to cause the spindle to select a boring bar and bushing from the cradle. The CNC and axes drive then move the bar and bushing to a predetermined boring position axially aligned with an interrupted line bore to be machined in a workpiece. The CNC then commands the spindle to advance axially toward the tool support, removably engaging the bushing in the tool support and continuing to push the boring bar through the engaged bushing while rotating the bar and boring the interrupted line bore in the workpiece.
