Abstract: ABSTRACT OF THE DISCLOSURE         A collar lock and seal assembly for releasably locking a well tool such as a pump in a well flow conductor, such as casing or tubing, and sealing with the flow conductor around the assembly to restrict flow to a path into the pump.  The assembly has an annular support surface engageable with a no-go shoulder in the flow conductor, radially movable locking keys for expansion into a locking recess in the flow conductor above the no-go shoulder, a longitudinally operable bypass valve, and interference fit annular seals.  First shear pins hold the assembly unlocked while running in and second shear pins are  activated to lock the assembly at operating position.  The seals and connected parts are coupled to resist rotation by the pump when locked in a well casing.  In operation the assembly is coupled in a tool train including an electric well pump, valves, and related structure.          The tool train is lowered on a cable in a well casing until the flow conductor no-go shoulder is engaged.  The bypass valve allows lowering in a closed liquid filled system.  Upon engagement with the no-go shoulder the keys are locked outwardly, the bypass valve is closed, and the seals form a pressure barrier around the assembly to limit flow into the pump and resist rotation of the assembly by the pump.  The collar lock dog and seal assembly is unlocked for removal by a longitudianl upward force applied to the cable.

Abstract: ABSTRACT     A punch guide and stripper is molded from plastics material to the exact configuration of the punch and is supported and reinforced by a rigid punch receiving member to engage a workpiece around the slug to be punched therefrom and strip the punch from the workpiece without bulging or damaging the work-piece. The plastics material is molded in situ around the active end or nose of the punch within a rigid metal punch guide at the punch exiting end of the guide to a height or thickness sufficiently to guide and laterally support the nose of the punch throughout its stroke. The surrounding rigid punch guide pre-vents lateral displacement or distortion of the plastics material and terminates either flush with or just short of the workpiece engaging face of the plastics material. The active end of the punch is of smaller diameter than the main body of the punch and may have any desired configuration with a shoulder extend-ing from the reduced section to the full diameter of the punch.          The punch is projected from the surrounding guide beyond the maximum stroke of the punch thereby providing a molding chamber or cavity bounded by the nose or head of the punch, the shoulder, and the surrounding punch guide. A hardenable viscous plastics material is poured into this chamber, cured or otherwise hardened to form the stripper body, the punch is retracted, and the hardened plastics material is ground flush with or just beyond the end edge of the guide to form the workpiece engaging face.          An undercut can be provided in the guide to further anchor the stripper body.

Abstract: ABSTRACT OF THE DISCLOSURE     Apparatus is disclosed for making a reticulated sheet material from a sheet metal strip which travels through the apparatus at a substantially constant velocity.  The appa-ratus includes rotary piercing means which pierces the central portion of the strip to provide slits arranged in a predetermined pattern; and plural rotary reticulating means providing simultaneously increased splay of the slits, and increased displacement of web segments out of the general plane of the central portion to form alternating rows of upwardly and downwardly directed openings.            Plural rotary forming means convert the flat sheet metal strip into a channel-shaped product.  A cutoff device is incorporated at the end of the line to cut the reticulated sheet product to desired lengths.            In a preferred arrangement, the sheet metal strip undergoes a preforming operation which rigidifies the strip prior to piercing, and undergoes a final forming operation after reticulation.  In an alternative arrangement, the strip undergoes a preforming operation after piercing but prior to reticulation, and undergoes a final forming operation following reticulation. In a further alternative arrangement, the strip undergoes a complete forming operation after piercing and reticulation.

Abstract: MULTIPLE LIP SEAL I ABSTRACT OF THE DISCLOSURE A multiple lip seal for oil and like fluids. The seal has an annular metal or like rigid casing portion of generally U-shaped cross section. A seal body is bonded to one flange of the U, and the body includes axially spaced apart, radially extending lips formed integrally with said body. In the preferred form, the flange about which the body is formed extends axially a distance at least as far as the extent of the multiple lip so that there is radial support for each of the lips, while the oppositely directed or other flange of the U-shaped casing remains free from rubber for mounting in a machine counterbore. The axially inner, intermediate and outer lips have different inside diameters in some cases and have the same diameters in other cases. Preferably, the body is thickest, and the radial extent of the lips is the shortest, at the axially inner portion of the seal. The seal assemblies can be made in either radially inwardly-acting form or in radially outwardly-acting form, depending upon the intended application. The U-shaped flange provides convenience of mounting and enables the minimal amount of rubber to be used, while providing the radial support for the axially inner seal lips referred to above.
