A continuous process for the drying and gel formation of solvent-containing gel- forming polymers, in particular polysaccharide derivatives, by flash cooling of suspensions of the polymers, and an apparatus for the drying of solvent- containing products are described. The process comprises the steps: metering the solven t- containing polymer having a solids content of 1 to 65% by weight and at a ...

A heat sealing/severing device for heat sealing thermoplastic films together . The device includes front and rear opposing jaws that are moveable between an op en position and a closed position. The open position defines a zone for inserting the thermoplastic films between the front and rear jaws. In the closed position, the front and rear jaws are proximate each other to compress the thermoplast...

Les deux lentilles (2H, 3P) du jeu sont du type à vision simultanée progressive, avec l'une (2H) des lentilles dont le profil progressif varie d e sorte que la puissance est plus importante au centre qu'en périphérie alors que po ur l'autre lentille (3P) c'est l'inverse. La gamme comporte deux séries de lentilles dont la puissance nominale s'échelonne suivant un pas prédéterminé, par exemple de 0...

A scroll compressor has a one-way drive for resisting and impeding objectionable reverse movement of the orbiting scroll member. The one-way drive includes a one-way clutch (150) interconnecting a drive shaft (30) with a stationary member (100) of the compressor through a resilient member (104). Reverse rotation of the drive shaft causes a loading of the resilient member which then operates to cus...

A plate formed with a plurality of regular projections projecting from both faces of'the plate can suitably be used. as a separator for a fuel cell. Projections on o ne face of the plate and projections on the opposite face of the plate are alternately and adjacently formed in at least one direction along a plane of a reference plate portion of a metal plate. The reference plate portion has not be...

A method for producing a process oil is provided in which an aromatic extra ct oil is added to a paraffinic rich feed to provide a blended feed. The blende d feed is then hydrotreated in a first hydrotreating stage to convert at least a portion of sulfur and nitrogen in the feed to hydrogen sulfide and ammonia. After stripping, the feed is subjected to a second hydrotreating stage to provide a pr...

Each of the discs (1-4) has a first group of segments (11) in which each segment field (13) has a symbol, and a second group of segments (10) in which each segment field (15) lacks a symbol and can be easily provided with a marking, e.g. by providing it with a surface for marking the symbol on. The number of segment fields in the second group is greater than that in the first group.

Information already present in a form suitable for audio transmission via the telecommunication network (11) is marked and then transmitted to the user via the network in audio information form. A user with a conventional telephone device (5) connected to a telecommunication network can access information stored on a device (3) in an information network (6), this information being specially marke...

The communication hub comprises a silence suppression block, a call admission block, and a control system. The silence suppression block is configured to compute a silence suppression gain for an incoming call based on a silenc e suppression realized for the incoming call a...

A removable snowboard boot liner made from Ethyl Vinyl Acetate with an air bladder attached therein and a method of mass producing such liners. An oily chalk like substance consisting of 90% sweet starch, 9% lubricant and 1% stearate is included between the two sheets that make up the bladder. The bladder is attached to the EVA before the EVA is folded, stitched, heated and molded. This allows the...

Flanges formed by powder metallurgical methods are used for joining, fo r example, exhaust pipes, instead of manufacturing flanges by stamping, forgin g and/or machining. This offers a number of advantages, including the ability to produce flange shapes which cannot be obtained by stamping, forging and/or machining.
