Title: Method for manufacturing refastenable fastening systems including a female loop fastening component and the products produced therefrom
Inventor: THOMAS DENNIS ALBERT
IPC: A61F13/62
Filed: 1995-10-26
Abstract: The invention is a refastenable mechanical fastening system including rows of female loops (22) joined to a substrate. The loops taper from the base (26) to the distal end (30) and are typically nonperpendicularly oriented relative to the plane of the substrate (24). The shanks (28) of each loop may also have an azimuthal angle relative to the machine direction of the substrate. Each loop includes an opening (32) for receiving a portion of the prong (34) of a male hook component. The loops are manufactured by the process of extruding liquid material through the apertures (56) of a depositing member onto a moving substrate (24) to form the base of the loop, stretching the liquid material in a direction parallel to the plane of the substrate, severing the stretched material to form a distal end which fuses with an adjacent amount of stretched material to form a loop. The advantageous usage of the fastening system (110) in an article of manufacture, such as a disposable absorbent article, and more specifically, a diaper (100) is also disclosed.

Abstract: Système de lit (20) permettant de limiter à une durée prédéterminée le temps de gonflage de chacun des différents matelas gonflables à ventilation (22) raccordés au système (20). Chaque matelas (22) comprend un raccord (30) équipé d'une cheville (48) sollicitée par un ressort qui permet d'activer un commutateur de pompe (56) lorsque le raccord (30) du matelas est convenablement appareillé avec un adaptateur de pompe (40), ce qui facilite le gonflage du matelas. La pompe (24) est programmée pour s'arrêter au moment prédéterminé et ne plus fonctionner tant que le commutateur de pompe (56) n'est pas réinitialisé. La cheville (48) est positionnée et conçue pour être rendue mécaniquement inopérable pendant le processus de réinitialisation du commutateur (56), ce qui permet d'éviter que chaque raccord (30) de matelas ne mette en marche le commutateur de pompe (56) une deuxième fois.

Title: Mercaptoketones and mercaptoalcohols and a process for their preparation
Inventor: LEVIN JEREMY IAN
IPC: A61P29/00
Filed: 1997-06-23
Abstract: This invention relates to matrix metalloproteinase (MMP) inhibiting compounds ofthe formula:     (see fig. I) where R1 is C1-C12 alkyl, straight or branched and optionally substituted by halogen, hydroxy, C1-C6 alkoxy, amino, carboxyl, C1-C6 alkoxycarbonyl, carboxamido, nitrile, mono- or di-(C1-C6)alkylamino, thio, C1-C6 alkylthio, aryl, -Oaryl or -OCH2aryl where aryl is optionally substituted with C1-C6 alkyl, C1-C6 alkoxy, carboxy, halogen, cyano, nitro, carboxamido, or hydroxy; and C1-C6 alkanesulfonyloxy. R2 is .alpha.-OH or .beta.-OH and R6 is H or R2 and R6 together are carbonyl; the chemical intermediates; and processes for the preparation of these compounds and the intermediates thereto. Matrix metalloproteinases (MMP) are a family of zinc-containing calcium dependent proteinases, including stromelysins, collagenases, and gelatinases. These MMP enzymes are capable of degrading the proteinaceous components of connective tissue and appear to be involved in tissue remodeling, i.e., wound healing and connective tissue turnover. Unexpectedly, the mercaptoalcohols with the S-configuration at the hydroxyl-bearing carbon have been found to be at least 4 times more potent than the analogous (R)-alcohols both in vitro and in vivo in inhibiting the MMP enzyme..

Filed: 1996-08-14
Abstract: This invention relates to novel opioid peptides for the treatment of pain as well as a method for the preparation thereof and pharmaceutically acceptable compositions comprising these peptides. The invention also relates to methods for controlling pain in patients using compositions of the invention and the use of said compounds in the preparation of formulations effective in pain treatment. The peptides of this invention have a high degree of selectivity for the .mu.-opioid receptor. The peptides of the present invention are particularly well-suited as analgesic agents acting substantially on peripheral .mu.-opioid receptors. Because these peptides act peripherally, they substantially avoid producing side effects normally associated with central analgesic action.
