Abstract: ABSTRACT OF THE DISCLOSURE Disclosed is an apparatus for and a method of propagating bubble domains along fixed guidance channel forming stripe domains by capturing them in move-able stripe domains and then moving the capturing moveable stripe domains. The memory plane comprises a non-magnetic Gadolinium Gallium Garnet (GGG) layer which is a supporting substrate upon which are successively formed by the liquid phase epitaxy (LPE) method:  a first stripe domain layer, a first non-magnetic spacer layer; a second stripe domain layer; and a third non-magnetic spacer layer upon which is formed the necessary propagation circuitry. The method of propagating the bubble domains involves forming fixed guidance channel forming stripe domains in the first stripe domain layer, orienting moveable stripe domains in the second stripe domain layer in a direction orthogonal to the direction of the fixed guidance channels, establishing bubble domains at selected ones of each fixed guidance channel, moveable stripe domain intersection and finally oscillating the moveable stripe domains in a direction parallel to the fixed guidance channels by a time-varying, i.e., temporally changing, localized bias field gradient.  A moveable stripe domain in a first position under a bias field gradient producing strip line captures a bubble domain, slowly moves the bubble domain a predetermined propagation direction under the strip line and along its associated fixed guidance channel into a second position under the strip line and then sub-sequently quickly moves back to its first position under the strip line allowing the bubble domain to escape therefrom leaving the propagated, escaped bubble domain in the second position under the strip line to be captured by a next adjacent downstream moveable stripe domain.  Successive capture, propa-gate, escape operations propagate all the bubble domains along each capturing moveable stripe domain, in parallel, in the downstream propagation direction through the memory plane.

Abstract: CORRUGATED TUBING WITH VARIABLE DEPTH CORRUGATIONS          AND METHOD OF MAKING THE SAME                       ABSTRACT OF THE DISCLOSURE    Helically corrugated tubing with corrugations of variable depth is manufactured in a twisting machine by rotating one end of a deformable tube relative to the opposite end and simultaneously applying axially directed forces to the tube to progressively develop the helical corrugations in the tube wall.  The depth of the corrugations is varied by means of a tapered mandrel which is located within the tube while the corrugations are being formed.          Tubing sections with variable depth corrugations define flow paths in which the effective cross sectional area varies correspondingly, and such sections are useful in various heat exchangers.

Abstract: CARBON FOAM FUEL CELL COMPONENTS     ABSTRACT OF THE DISCLOSURE      In an electrochemical cell, such as a fuel cell, the gas distribution layer, which is the layer of material disposed directly behind and contiguous with the catalyst layer, is made from gas porous open cell carbon foam.          Vitreous carbon foam is preferred.  Vitreous carbon foam is extremely corrosion resistant to many of the very reactive chemicals which might be used as an electrolyte in a fuel cell, such as phosphoric acid.  It also has low electrical resistivity, good thermal conductivity, and can be made very thin and inexpensively.  Preferably the cell catalyst layer is applied directly to one surface of the foam layer.

The sheet molding compound on the roll is covered on both sides with a vinyl film.  The nipper rolls, in addition to drawing the sheet molding compound from the reel, also removes the vinyl film.  The top film on the sheet molding compound is wound on the upper nipper roll and the vinyl film on the lower surface of the sheet molding compound is wound on the lower nipper roll.       The nipper rolls are rotated by an air motor and the pressure between the nipper rolls is controlled by air cylinders.  An operator controlled air valve, when operated, causes the nipper rolls to rotate.  The pres-sure between nipper rolls is controlled by a separate air valve.  By this means the vinyl film can be re-covered in neat rolls.

Abstract: ABSTRACT           A threaded fastener incorporates a long-pitch helical thread rolled on a cylindrical blank of predetermined diameter, leaving untouched a section of the blank between adjacent turns or convolutions of the thread.  The thread has a crest which is greater in daimeter than the blank and a root which is smaller in diameter than the blank.  The contour of the thread in a plane including the longitudinal axis of the screw is unsymmetrical about a line perpendicular to the axis and passing through the crest, the flank of the crest facing the head end of the screw being more nearly perpendicular to the axis than the flank facing the work-entering end of the screw.  At each juncture between the root of the thread and the adjacent untouched blank sections, there is an outwardly extending helical bur or crest which functions as an auxiliary thread to improve the holding power of the screw.

Abstract: ABSTRACT         SPONGE CARRIER ADHESIVE PROCESS     A flexible, e.g. polyurethane, open cell foam sheet is impregnated with a controlled amount of a liquid poly-merizable resin system which cures at ambient tempera-ture, and the resin impregnated sheet is immediately chilled at a suitably reduced temperature, e.g. 40°F or below, to arrest polymerization or hardening.  The resulting resin impregnated sheet is stored at such reduced temperature.  When needed for adhesive bonding the chilled resin impregnated sheet, cut to the de-sired pattern or size, is applied between the surfaces of objects to be bonded, e.g. fiber reinforced poly-urethane insulation blocks and plywood strips, or such insulation blocks and the steel hull of a liquid natu-ral gas (LNG) container or marine tanker.  With or with-out the application of bonding pressure, as the temp-erature of the resin impregnated sheet rises to am-bient temperature, curing of the resin in the sheet to the solid state takes place, and bonding of the ad-jacent surfaces of the objects occurs, substantially without extrusion of any excess resin from the sheet, the open cell foam sheet containing the cured resin forming an integral part of the resulting bondline.
