Patent number: 8146388Abstract: An apparatus for drawing a glass ribbon including a shroud surrounding the glass ribbon and an edge roll that penetrates the shroud to contact the glass ribbon. The apparatus includes regulating a pressure within the seal assembly to be equal to or less than a pressure within the shroud and prevent ingress of relatively cooler outside gas into the hot interior of the shroud. The edge roll utilizes an air bearing to minimize friction that can produce periodic fluctuation of the ribbon as the edge roll is displaces in response to variations in the ribbon thickness or equipment dimensions.Type: GrantFiled: October 29, 2009Date of Patent: April 3, 2012Assignee: Corning IncorporatedInventors: James G.

Patent number: 4838145Abstract: A hydraulic system has a rotary valve which controls multiple hydraulic dces such as double-acting piston type actuators and which prevents deactivated devices from creeping. The valve has an outer housing and a rotatable inner member which form high pressure inlet, low pressure outlet, and control stages. The control stages utilize partial commutators (part circumferential grooves) and ports on the valve member selectively to couple control ports of the housing respectively to the inlet stage or the outlet stage by rotating the inner valve member (the control ports being connected to the hydraulic devices). At the inlet and outlet stages, the valve member has full annular commutators which communicate continuously with a high pressure inlet port and a low pressure vent port of the housing as the valve member is rotated. The valve member also has internal passageways which connect each control stage partial commutator and fluid port to either the inlet commutator or the outlet commutator.Type: GrantFiled: June 18, 1987Date of Patent: June 13, 1989Assignee: The United States of America as represented by the Secretary of CommerceInventors: Alexander H.

Patent number: 4685661Abstract: A programmably controllable vise has mechanisms for automatic adjustment of orkpiece position relative to three orthogonal axes. The positions of the vise jaws (during clamping) establish workpiece position along a first axis, and stop members (e.g., piston actuated stops) selectively extendable from the jaws establish workpiece position along a second axis. Two levelling bars supported adjacent the jaws by respective servo-actuators (e.g., double-acting piston type actuators) which adjust the bars along the jaws establish workpiece position along the third axis, as well as workpiece tilt about the first and second axes. Because the adjustments may be made automatically, the vise may operate unattended, with workpieces being loaded and unloaded by a robot. The vise jaws preferably incorporate replaceable jaw elements which are constructed for attachment and removal by a robot and which may be machined to accommodate non-prismatic workpieces.Type: GrantFiled: June 21, 1985Date of Patent: August 11, 1987Assignee: The United States of America as represented by the Secretary of CommerceInventors: Alexander H.
