Abstract: L'invention porte sur un mélange de polymères à forte résistance à la chaleur, à faible dégagement d'hexane et à module d'élasticité contrôlable. Ledit mélange comporte au moins un premier polymère d'éthylène sensiblement linéaire, le composant A, et au moins un deuxième polymère d'éthylène à ramification homogène, à ramification hétérogène ou à densité peu élevée. Sous forme de film, le mélange se caractérise par sa température de début de thermoscellage t sensiblement inférieure à son point de ramollissement Vicat ainsi que par sa forte adhérence ultime à chaud; sous forme d'articles moulés, le mélange se caractérise par son fort gauchissement sous l'effet des micro-ondes et son faible module d'élasticité. Ledit mélange est particulièrement bien adapté pour constituer la couche étanche de structures multicouches servant par exemple pour des produits à cuire dans leur emballage, des emballages remplis à chaud, ou des films de protection rétractables; en ce qui concerne les articles moulés, le mélange peut servir de récipient (couvercle compris) de stockage d'aliments en réfrigérateur et en four micro-onde conservant à basse température une souplesse en facilitant l'ouverture.

Title: Winding machine for winding a travel web of paper
Inventor: KRUGER JENS
IPC: B65H18/20
Filed: 1997-06-20
Granted: 2000-06-13
Abstract: To achieve this object, the winding machine of the invention includes two parallel wound web roll support rollers which are spaced apart and on which the roll being wound is supported. The gap between the support rollers and below the supported wound roll is to be pressurized. A pressure chamber is defined by the support rollers, the wound roll above, and from below by a cross member which bridges over the distance between the support rollers and closes the bottom of the gap. End walls close the ends of the chamber.      The cross member is movable between a sealing position where it is in contact with, or at least is sealed with, the two support rollers and bridges the gap between them to an open position where it opens the gap between the support rollers. The cross member is movable either down out of the gap, laterally out of the gap, or a combination of both, by reciprocating swinging, or oblique movement, and the like. The cross member has at least one passage which connects the pressure chamber with a source of compressed air through an intermediate conduit. An elongate transverse distributing pipe arranged at a distance from the cross member has a pressure connection through the conduit leading to the cross member.

Granted: 2007-08-21
Abstract: Disclosed is an air-flow-directing grille assembly of the type having two frame members and a grille bar supported by such frame members for pivoting movement about a grille bar axis. In the improvement, each frame member has a hole, the bar has an axle extending through the holes and each hole and the axle are cooperatively sized to provide a friction fit between such hole and axle. The grille bar is thereby frictionally retained in a position. A new method for making a grille assembly includes providing a pair of frame members, each having a bole therethrough of a first diameter. A grille bar is provided to have an axle with a second diameter at least equal to the first diameter. The axle and the frame member holes are urged into frictional engagement with one another and the grille bars will thereby hold a selected air-flow-directing position.

Title: Low ph skin-treatment composition
Inventor: STRUEWING SHARON
IPC: A61Q19/00
Filed: 1996-04-11
Granted: 2007-07-31
Abstract: A low pH skin-treatment composition employs cationic surfactants generally known to be skin irritants and a fatty acid, together with a hydrocarbon component in an oil-in-water emulsion. The addition of fatty acid to the cationic surfactant appears to form a complex which prevents the cationic surfactant from irritating the skin and at the same ti me substantially reduces pH of the composition. The resulting composition is not skin irritating, and reflects a pH of about 2-4. The composition may be used to restore pH of skin after exposure to alkaline compositions, and as a vehicle for the administration of active agents having an acidic pH.

Title: Digital video recorder error recovery method
Inventor: MILLER ROBERT HOWARD
IPC: H04N5/44
Filed: 1997-01-31
Granted: 2002-03-26
Abstract: A method for operating a video recording apparatus in one of a digital recording mode and an analog recording mode. The method involves recording a digital video bit stream in the digital recording mode and switching to the analog recording mode for recording the corresponding analog video signal in response to a fault condition. For example, the fault conditions may occur in response to improper copyright information, an analog recording media being loaded into the video recording apparatus or the digital video bit stream being absent while the video recording apparatus operates in the digital recording mode. The fault condition may be indicated to a user and switching to a different mode, such as the analog recording mode, may occur in response to receiving a user initiated command responsive to the indicated fault condition.
