Abstract: A method for property modification of bulk polymers, including polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), natural rubber and the like, by initially treating a short chain organic acid, having a carboxylic group (with dissociation constant between 10-2 to 10-6 cm-1, and less than 8 carbons); with an oxide, peroxide, hydroxide or halogen compound of a Group IA, IIA or IIB metal, or the metal itself, and preferably a divalent alkaline earth metal, for forming a metal ligand or complete metal salt of the acid. The bulk polymers, are thoroughly mixed with the complex metal salts, such as in an extruder, and free radicals are introduced into the mixture, such as by means of addition of a highly oxidizing material, such as a peroxide, to functionalize the bulk polymer with ionic polymerization sites, with a resultant homopolymer formation between the organic metal salt anion and the bulk polymer, as catalyzed by the metal cation at such sites. The polymerization is a substantially non-cross linked ionic one resulting from the dissociation parameters and short chain length of the complex metal salt. The metal salt anion appears to fill in gaps in the bulk polymer but without cross-linking. Resultant homopolymer materials including those containing bulk polymers of PE, PP and PVC show improvement in flow rate, elongation and tensile strength over the original bulk polymer materials, and natural rubber behaves like a thermoplastic polymer.

Title: Absorbent articles having improved surfactant-treated hydrophilic topsheets
Inventor: LEE YANN-PER
IPC: A61F13/511
Filed: 1996-03-20
Granted: 2001-10-02
Abstract: The present invention provides an absorbent article having a topsheet treated with a silicone-based surfactant to impart hydrophilicity. The absorbent article preferably includes a first, apertured, macroscopically expanded, three-dimensional, polymeric topsheet and preferably includes a second, apertured, macroscopically expanded, three-dimensional polymeric topsheet underlying the first topsheet. The multiple topsheets provide improved masking of bodily fluids absorbed and retained by the absorbent core. The first and second topsheets preferably include surfactants which impart hydrophilicity to differing degrees, and which preferably are selected from diverse surfactant categories. The use of a silicone-based surfactant imparts improved tactile qualities to the wearer-contacting surface of the first topsheet in comparison with non-silicone-based surfactants. These characteristics of the silicone-based surfactant provide improved dryness and cleanliness of appearance through low retention of fluid material at or near the surface of the topsheet itself and promoting fluid movement along the wetted surfaces and downward into the absorbent core.

Title: Self-locking lock
Inventor: GONSER GERHARD
IPC: E05B63/20
Filed: 1998-01-20
Granted: 2001-11-13
Abstract: The invention relates to a self-locking lock with a bolt, a lock swing catch andan auxiliary swing catch, in which the bolt and lock swing catch move outwardly to a locking position in spring-loaded manner and with the door closed, and are there lockable by a slide plate whilst the auxiliary swing catch presses on a locking plate. With the door open, the bolt is held back in a housing of the lock and is arrested by the auxiliary swing catch by means of the slide plate. In order to provide a lock secure against manipulation and reliable in operation, where an uncontrollable extension of the bolt is particularly effective prevented even in intermediate states of the opening and closing process, on opening the bolt leads compared with the lock swing catch and is arrested completely retracted in the housing of the lockwhile the lock swing catch is provided with a widening, for instance, a pivotable, spring-loaded swing catch part. As a result, the lock swing catch engages for a longer time on the locking plate and lags behind the auxiliary swing catch, so that the slide plate and bolt are arrested until the auxiliary swing catch arrests the slide plate and bolt. The lock swing catch widening has no effect on closing.
