Abstract: ELASTIC LEG DIAPER AND METHOD AND   APPARATUS FOR ITS MANUFACTURE             ABSTRACT OF THE DISCLOSURE The present invention is an elastic leg diaper and a method and equipment for its manufacture. 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. Diapers made using one of these materials as a backing sheet can be conventionally assembled. After assembly, the marginal areas, which may be either or both of the transverse and longitudinal margins, may be heated to a sufficient temperature for shrinkage to occur in the backing sheet. This shrinkage will only occur when the backing sheet is unrestrained. The method provides for the maintenance of longitudinal tension in the central portion of an end-to-end assembly of diaper units while relaxing the edge tension on the units. This is accomplished in the present diaper making machine by passing the assembly over a series of rollers which are of cylindrical form in the central portion and are tapered at each end. The marginal portions overhang the tapered portion where they are free to shrink after heating. If an elastic waist construction is desired, the diapers are similarly heated in an transverse direction whereupon any transverse tension is relaxed to enable transverse shrinkage to occur. While the preferred diaper uses the heat shrinkable material as the entire backing film, it is within the scope of the invention to insert ribbons of this materialalong the appropriate marginal edges of the diapers and use conventional backing film materials.

Title: Color display system and cathode-ray tube including a dipole lens for electrostatic convergence
Inventor: ALIG ROGER C
IPC: H01J29/50
Filed: 1987-06-05
Granted: 1991-01-08
Abstract: Abstract A color display system includes a cathode-ray tube and a yoke.  The yoke is a non-converging deflecting type.  The cathode-ray tube has an electron gun assembly for generating and directing three electron beams, located at the corners of an equilateral triangle, along paths toward a screen of the tube.  The electron gun assembly comprises three electron guns each including electrodes that comprise a beam-forming region and electrodes that form a main focusing lens in the path of an electron beam. The main focusing lens is formed by at least two focusing electrodes. The focusing electrode closest to the beam-forming region includes a separated part adjacent to the path of the electron beam.  Each separated part forms a portion of a dipole lens structure in the electron beam path.  Means are provided for applying dynamic signals to the separated parts which are related to the deflection of the electron beams.  The dipole lens structures establish electrostatic dipole fields in the path of the three electron beams that cause the beams to converge at the screen for all angles of deflection.

Abstract: AUTOMATIC DROP-OFF DEVICE FOR PERFORATING GUNS     Abstract A perforating gun assembly is set forth in the present disclosure.    It incorporates an upper elongate body having a firing head.  The body supports a lower carrier which encloses one or more shaped charges which are positioned for forming perforations into a formation of interest.   The sole means by which the carrier is attached to the body utilizes an upwardly extending set of parallel collet fingers having enlargements on the end. The collet fingers are locked in position against a conforming shoulder.   Locking is achieved by a pressure movable piston.  The piston is forced by detonation gases from the shaped charges away from the locked position, and the collet fingers are then permitted to flex,  pulling free of the conforming shoulder to enable the carrier to drop from the elongate body.
