A 2,2-difluoro-2-desoxycarbohydrate is used to prepare antiviral nucleosides.

To produce the bags, two tapes (15, 16) of a sealable material are guided between two rotating sealing rollers (10). Three edges of the bag (19) are first sealed, after which a metered quantity of filling material is introduced from a filling material container (3) through the edge of the bag which is open at the top, and then the bag is fully sealed. To permit production of bags (19) of any size ...

The invention provides method and apparatus for forming upper stops of a concealed type slide fastener. A concealed type slide fastener comprises a pair of fastener stringers each consisting of a fastener tape having a turn-up along one side thereof and fastener elements of thermoplastic resin secured to the turn-up. Portions of the elements are fused to form upper stops. In the method and apparat...

Polymeric materials (and articles made therefrom) including polyurethanes, polyesters, polyolefins, polyamides, polysiloxanes, vinylic and acrylic polymers are rendered biocompatible by including with the polymeric material hyaluronic acid or a salt thereof. The hyaluronic acid may be coated onto the surface of the polymeric material, dispersed throughout the body of the polymeric material, or bot...

A device for connecting a plurality of elongate objects e.g. pipes comprises a rigid open-ended tube (20,25) that is capable of being joined to the elongate objects to form a connection between the objects. The tube has a dimensionally recoverable skirt (2l,27) in the region of one, and preferably each end thereof which can be recovered about the join between the tube and object, and the device ha...

An apparatus and a method for forming a compartmentalized flexible plastic enclosure with selectively communicable compartments utilizing a pair of plates and at least one thin plastic sheet sandwiched between the plates. One plate has a surface which is conventionally plane facing the sheet and the other plate has a surface which includes a network of ridges facing the sheet and forming a sealing...

An injection port for injecting fluid through a needle into the contents of a container. The port has a covering film securing a sterile pad of resealabie material to a base member having a portion pierceable by a needle. A tear strip is heat welded to the cover so as to form a removable tab comprised of a welded tear strip section, a welded cover section and an unwelded lap forming a grip for rem...

An improved method for forming closed burstable pouches having breakable seals. The method includes selection of a laminated polymeric film which has two principal layers-an outer layer which is responsive, and an inner layer which is non-responsive, to a radio-frequency (RF) welding field, the inner layer being of a biaxially-oriented polymeric material such that its cohesive strength in its thic...

Disposable diapers having elasticized waistbands which are shaped to conform to the wearers' waists and methods of making them. The shaped disposable diapers are made by affixing an elastomeric material having a heat unstable state and a heat stable and elastic state to the diaper while the elastomeric material is in its heat unstable state and then heating the elastomeric material while the diape...

The disclosure relates to a boom structure in an oil-spill-combatting system. A water craft (2) has booms extending to each side, and the ends of an oil collecting rope (4) are secured to the ends of the booms. Oil is recovered from the rope by running the rope (4) through an apparatus (3) which is situated at the aft of the craft (2). The rope is run first in one direction and then in the opposit...

A sanitary napkin. The sanitary napkin comprises a central absorbent pad and flaps extending from each longitudinal edge of the central absorbent pad. The body of each flap contains a flexible axis about which the flap can fold on itself. The sanitary napkin preferentially bends at the line of juncture between each flap and the longitudinal edge of the central absorbent pad. When the sanitary napk...

A sanitary device, e.g. a sanitary napkin is provided which has an absorbent matrix and a fluid impervious baffle. Part of the fluid impervious baffle is a heat fusible sheet which is adhered to the absorbent component by fusing. The absorbent component may have heat fusible material interspersed therein and may have a fluid pervious upper layer which is essentially coterminous with or wraps about...

An absorbent structure comprises a moisture-permeable layer, and an absorbent batt of loosely-compacted, cellulosic fibers and containing a reservoir capable of receiving body fluid discharged. The reservoir is formed by compression of the fibers in the reservoir zone.

A disposable diaper comprises a liquid-permeable surface sheet, a liquid-impermeable backing sheet, and an absorbent pad sandwiched between the two sheets, characterized in that water-absorptive, shrinkable fiber strings, which contract lengthwise on contact with water and are rendered stretchable, are secured to the two sheets, extending midway longitudinally of the diaper in parallel along, but ...

The invention provides a novel composition useful as a heat-resistant coating material on the surface of a metal or ceramic article or as an adhesive agent for bonding metal articles, ceramic articles, or articles of a metal and a ceramic.
