A method of production of disposable diaper pants or disposable sanitary panty with openable and resealable side panels. A row of absorption bodies is applied on a continuous web of inner or outer cover sheet material, after which a continuous web of outer or inner cover sheet material is applied and secured to the web with absorption bodies at parts lying outside the absorption bodies to form a web of diaper pants blanks. First side panels having two parts connected by a detachable and resealab...

The improved isotope separator comprises a vacuum vessel, a plasma generator located substantially in the center of the vacuum vessel, an electrode bounded by a hyperboloid of one sheet and a pair of electrodes bounded by a hyperboloid of two sheets, said electrodes being located within the vacuum vessel in such a way as to surround the plasma generator, a power source for supplying said electrodes with a fixed voltage and a pulsating voltage, and magnetic field generating means located outside ...

A method and system for separating radioactive waste containing volatiles, into light ions and heavy ions, includes a loader/transporter for transferring the waste into a high vacuum environment in the chamber of a plasma processor. During this transfer, gases of the volatiles are released from the waste, collected in a holding tank, and subsequently ionized in the chamber. As the volatiles are ionized, the ions are directed by a magnetic field into contact with the waste to vaporize the waste. ...

This method of making a draw sheet, suitable for hospital use, has plastic film to which is laminated a highly absorbent non-woven fabric over only that portion of the sheet which is on top when in use. The method is a continuous process that advances the web of plastic film from a supply roll and progressively folds film from both sides of the web over the top of the mid portion which is to be laminated to the absorbent material. The web becomes in effect a flattened tube. A web of the unwoven ...

The activity maintenance of the plasma initiators used during the upgrading of a hydrocarbon feedstock in a reaction zone using microwave radiation can be improved if molecular hydrogen is added to the reaction zone such that the weight ratio of carbon (in the molecules in contact with the plasma initiators) to hydrogen is maintained at less than 6:1 during upgrading.

Process for producing (cigarette) packs from blanks which are drawn off from a continuous material web wound as a reel, regions of glue arranged on both sides of the material web serving for connecting folding tabs. The regions of glue are positioned in different lines of the material web such that, in the would state, regions of glue on one side of the material web do not overlap with regions of glue on the other side.

The present invention pertains to a method wherein a concavoconvex cutting line is applied repetitively in a periodical way in the longitudinal direction of a continuous first web to form first and second partial webs; said first partial web is offset with respect to said second partial web in the longitudinal direction by a prescribed interval so that the concave edges and the convex edges of the first and second partial webs are positioned opposite to and aligned with each other, whereafter a ...

C.sub.2 + hydrocarbons can be effectively converted to primarily unsaturated hydrocarbons and hydrogen using microwave radiation in the presence of at least one plasma initiator that is capable of initiating an electric discharge in an electromagnetic field.

An apparatus comprising a mechanism for loosely folding a strip of assembly of a synthetic resin semipermeable membrane and a spacer in pleats of uniform or uneven width, and a mechanism for completely folding the folded portion of the assembly within a holding case. A plurality of such holding cases are utilized to prepare completely folded portions of assembly in succession as individually held in the cases to obtain pleated semipermeable membrane elements by a continuous operation.

A process for separating a product web into discrete products is disclosed. The process can include transporting the product web in a machine direction, creating a line of weakness in the product web, and separating the product web into discrete product elements at the line of weakness.
