US Patent:

Filed:

May 7, 1980

Appl. No.:

6/147680

Inventors:

Angel C. Martinez - La Habra CA

Assignee:

Borg-Warner Corporation - Chicago IL

International Classification:

F16J 1534

US Classification:

277 15

Abstract:

A balanced mechanical seal between two zones having different fluids, at least one of which may be corrosive, abrasive, of different lubricity, of elevated temperature and with other undesirable properties or characteristics. A buffer fluid is introduced into one zone at a constant rate so as to flow to a location radially inwardly of contacting seal faces and then radially outwardly of said seal faces. The flow serves to cool and lubricate the seal faces and substantially prevent the flow of fluid from the other of the zones radially inwardly across the seal faces. The ratio of areas which determines the seal balance is such that in the direction of buffer fluid flow it is of relatively low value. However, in the opposite direction of fluid flow, the balance is a much higher value. Thus in the event of buffer fluid failure, flow of the undesirable fluid across the seal faces is substantially prevented, thus preserving the faces from substantial damage from that undesirable fluid.

Abstract:

A versatile wall decorating system is provided with self-adherent, pre-cut decorative appliques that removably attach onto substrate sheets adhered to walls. Both the appliques and the substrate sheets utilize a reusable, non-permanent adhesive coating. Such a coating permits rearrangement of the appliques on the substrate sheets and rearrangement of the substrate sheets on the walls, in a peel-off/press-on manner. Each applique provides decorative imagery of a common theme. Additionally, the substrate sheets may include decorative imagery which cooperates with the appliques to create a decorative wall scene. The appliques can also be adhered to surfaces other than the substrate sheets. The decorative scene presented by the wall decorating system is easily changed by repositioning the appliques or by removing appliques of one theme and substituting therefor appliques of a new theme.
