Granted: 1993-01-26
Abstract: 13725b ELASTIC LEG DIAPER AND METHOD AND  APPARATUS FOR ITS MANUFACTURE               ABSTRACT OF THE DISCLOSURE The present invention is a method for manufacture of elastic leg and/or waist disposable diapers. A preferred form of the diaper uses for the entire moisture impermeable backing sheet an elastomeric material of the type that is heat unstable and relatively inelastic in its unshrunk form and stable and relatively elastic in its heat shrunk form. Numerous materials of this type are available. Included among them are block copolymers which include a rubbery material as one component, polyurethanes, and irradiated polyethylene. Alternatively, a conventional polyolefin backing sheet may be used with strips of the heat shrinkable elastomeric material bonded in appropriate marginal locations in the waist or leg zones. These marginal zones are then heated to an appropriate temperature and any tension on the sheet relaxed to allow shrinkage and elasticization to take place. Following this step the sheet may then be retensioned to about its original dimensions and combined with a cover sheet and absorbent filler to form diapers.

Title: Sleeper for the attachment of covering material to a surface
Inventor: GRONAU ARTHUR W
IPC: E04F15/04
Filed: 1989-08-07
Granted: 1994-05-17
Abstract: ABSTRACT OF THE DISCLOSURE           A sleeper is disclosed comprising a guideway, a resilient strip, a nailing bed and a spring.  The guideway is an elongated channel of C-shaped cross-section with three fully closed faces and a partially open face.  A plurality of the guideways are fastened to the floor base and the resilient strips placed in the bottom of the guideways.  The nailing bed is an elongated wooden element with an elongated protrusion. The nailing bed defines an inverted T-shaped cross-section and is placed in each guideway above the resilient strip.  The protrusion of the nailing bed extends through the partially open face for attachment to the flooring material.  The nailing bed is shorter than the guideway to leave sufficient room within the guideway at at least one end of the guideway for the spring.  The spring is inserted with one end against the end of the nailing bed.  The spring is then com-pressed and a stop inserted through the guideway to maintain the spring in the compressed condition.  The spring acts to bias the nailing bed and the attached flooring material in a direction defined by the guideway.

Abstract: A valve plug having a valve plug housing shaped to fit in a bonnet cylinder of steam control valves has a pressure seal ring groove for holding a pressure seal ring therein. The pressure seal ring groove has a pair of walls and a bottom surface end and anti-wedging relief groove formed in one wall of the pressure seal ring groove adjacent the bottom surface thereof to prevent the wedging of a pressure seal ring between a valve plug and a bonnet cylinder bore wall.

The valve plug housing pressure seal ring groove can be an annular groove having an annular pressure seal ring therein and the relief groove can be an annular groove formed in one wall of the pressure seal ring groove adjacent the pressure seal ring along the seal ring contact surface of the pressure seal ring. The relief groove has a pair of sidewalls and a bottom surface with one wall forming an extension to the pressure seal ring groove bottom surface so that wear on the pressure seal ring groove wall enlarges the width of the pressure seal groove to prevent a step forming therein and wedging of the pressure seal ring between the valve plug and the bonnet cylinder bore.
