Title: Machine a couler de type a roue rotative
Inventor: SHERWOOD WILLIAM LYON
IPC: B22D11/06
Filed: 1996-07-18
Abstract: Roue à couler qui porte une paroi (8) de moulage rotative de rayon interne sur son bord et possède un secteur (11) de moulage non rotatif comportant au moins un segment de moulage (10) rigide possédant une paroi (12) de moulage de rayon externe, et oscillant de manière circonférentielle autour d'un support fixe (34) externe. Ladite roue à couler comporte sur sa périphérie des rails de guidage (5, 6) circonférentiels le long desquels des rouleaux (15) de guidage à fonction de came portant les segments non rotatifs (10) agissent pour maintenir un espace libre étroitement régulé entre les bords des parois de moulage de rayon interne (9) et de rayon externe (12) pendant toute la durée de la rotation. Le secteur de moulage (11) non rotatif peut être conçu en tant qu'ensemble unique ou en tant que segments multiples (10) fixés ensemble par charnière en vue de l'oscillation provoquée par un seul oscillateur (32), chaque segment comprenant son propre système de rouleau de guidage. Chaque paroi intérieure de caisson se dédouble pour constituer la paroi (12) externe d'enveloppe de moule, qui peut être refroidie par de l'eau pulvérisée (39) projetée par des buses (38), ou par fermeture étanche et mise sous pression de segments (10) à travers lesquels est maintenu un flux régulé de liquide de refroidissement. En raison de la construction rigide de la roue et de la fermeture, la présente invention peut également être adaptable à la coulée de planches larges pour des laminés plats, par simple augmentation de la largeur de la roue par rapport à la profondeur de l'enveloppe de moulage. Certains modes de réalisation comportent des digues (44) latérales à largeur réglable pour régler la largeur de la planche coulée, et un espace supplémentaire pour des buses d'entrée intégrées pour la coulée de planches minces. La présente invention est adaptable pour toute une série de produits sous forme de filet métallique comprenant des sections structurales. Dans un mode de réalisation, la présente invention comporte des segments (90) de rouleau non oscillants qui portent une série de cylindres non commandés (69) au lieu de la paroi (12) de moulage de rayon externe, après formation d'une peau solide cohésive sur la partie en cours de moulage. Cela élimine considérablement la friction de fermeture et assure un contact non coulissant à pression régulée entre le produit de moulage et la roue, ce qui permet la propulsion dudit produit par friction statique le long de l'arc de contact avec la roue, plutôt que par traction à l'aide de cylindre de retrait suivant l'évacuation, ou par des cylindres entraînés le long de la partie de confinement. Divers autres caractéristiques et avantages de l'appareil sont également décrits.

Inventor: ROTSTEIN ORI
IPC: A61K31/121
Filed: 1999-04-09
Abstract: Manipulation of the intracellular redox state has been shown to alter cell activation pathways with resultant changes in cellular function. Previous studies have suggested that thiol oxidation, using the glutathione-depleting agent diethyl maleate, was able to inhibit endothelial cell activation. We hypothesized that this agent might exert beneficial effects following endotoxemia in the rat, a model where transendothelial migration of neutrophils is central to the development of hepatocellular injury. Sprague Dawley rats treated intraperitoneally with LPS (200 µg/kg) plus D-galactosamine (600 mg/kg) developed hepatocellular necrosis, as evidenced by liver enzyme release and morphological changes. Pretreatment with diethyl maleate abrogated this injury in a dose dependent fashion. Histology revealed reduced neutrophil accumulation in both the parenchyma and sinusoids, consistent with reduced neutrophil sequestration and transendothelial migration. This effect appeared to be related to the ability of diethyl maleate to prevent LPS-induced upregulation of both VCAM-1 mRNA and ICAM-1 mRNA in the liver as well as reducing TNF mRNA expression. In addition, diethyl maleate prevented hepatocyte apoptosis followings LPS treatment. The effect was reproduced when TNF was used as an inflammatory stimulus, suggesting a direct protective effect on the hepatocyte. Taken together, these studies show that redox manipulation through thiol oxidation may represent a novel approach to preventing liver necrosis and apoptosis in inflammatory conditions.

A thumb rest extends outward from the outer flange along the lower edge portion thereof and centrally thereof. This rest has an upwardly curving outer end portion which tends to assist in retaining the thumb on the rest and preventing any accidental slipping therefrom. An upper flange, which is preferably coextensive with the length of the rim mount, tapers upwardly and inwardly relative thereto, providing a scraping edge against which the filled spoon can be easily slid to level the food, preferably no higher than the upper rim of the spoon. It will also be recognized that this upper flange an effective splatter shield for the outwardly positioned thumb. As a variation, the handle accessory can also incorporate an elongate support projection integral with the outer flange and extending from the lower edge thereof in alignment with the thumb rest. This support projection arcs downwardly and inwardly beyond the inner flange so as to underlie the side and bottom of the bowl for a substantial transverse portion thereof. In this manner, the support projection itself provides for a direct support of the bowl with or without an actual positioning of the hand beneath the bowl.
