摘要： The novel method comprises (1) producing in one major surface of a metal masking plate an array of substantially-parallel grooves separated by ridges of plate metal, (2) producing in the other of said major surfaces an array of generally rectangular-shaped depressions opposite the grooves and extending only partially through the plate and less than the distances required to connect to said grooves, (3) filling the grooves with an electrically-insulating material, (4) removing the ridges of metal down to depths to connect with the depressions, thereby producing an array of substantially-rectangular apertures through the plate and electrically-insulating strips across the apertures and (5) covering selected surface portions of the electrically-insulating material with an electrically-conducting material. Before step (3), the surface of the grooves are coated with a resistive or semiconductive material, such as black iron oxide.

摘要： A bidirectional disappearing plug member and plug assembly is capable of blocking pressurized fluid flow from opposing axial directions in a flowbore. In a preferred embodiment, the plug member, which blocks flow through the flowbore, may be readily and at least partially dissolved through the application of at least one pressurization and depressurization within a tubing string above the plug assembly. Construction of the plug assembly permits the plug member to be conveniently emplaced in a fluid-filled wellbore by permitting fluid flow around the plug member during the emplacement process. The plug member may then be secured within the plug assembly to block fluid flow from either axial direction. Operation of a plug rupture sleeve or mandrel, for at least partially dissolving the plug member, may be controlled by a ratchet assembly or linear indexing apparatus requiring multiple pressurizations and depressurizations before the plug member is exposed to wellbore fluids and thereby at least partially dissolved.

摘要： A steam pressing machine comprising a perforated steam platen and means for pre-heating the platen, e.g., an electric heater, is improved by providing it with a source of superheated steam for ejection out of the platen, rather than saturated steam. This allows the use of lower platen temperatures, and, therefore, lower fabric temperatures. Pressing is faster, because the fabric takes less time to cool, and nap-crushing and shining are less of a problem.
