Non-free flowable molding powders of modified polytetrafluoroethylenes Non-free flowable, non-dusting molding powders with a bulk density of more than 450 g/l are obtained when a suspension polymer of tetrafluoroethylene with a content of 0.01 to 1 % by weight of units of at least one perfluoro(alkyl-vinyl) ether is ground to a particle diameter of 10 to 50 .mu.m and agglomerated in water.

The invention relates to a device and a method for the identification of fluorescing follicles that can be follicular impactions and/or microcomedones (clinically non-evident acne lesions), and/or comedones (clinically evident acne lesions) and/or bacteria on the face or other skin surface area. The inventive device allows thedetection of both types of follicular fluorescence (yellow/green and ora...

A rock, bit grease composition is prepared by combining synthetic polymer lubricant basestocks comprising a first ethylene-alphaolefin polymer having an average molecular weight in the range of from 3,500 to 4,000, and a polyisobutylene polymer to form a first master. A metal complex soap base thickener is prepared by combining a synthetic polymer lubricant basestocks comprising a second e...

A software partitioning tool is disclosed. Based on a visual display of an application that shows program objects and the connections or interactions between the objects, an internal representation of the application is defined. As the user interacts with the visual display of the application, creating new partitions and relocating program objects in the new partitions, the internal representation...

An optical communication system is described which comprises an optical source; an optical modulator, receiving a transmission signal having frequencies included within a signal band and adapted to emit a modulated optical signal of a predetermined optical bandwidth; an optical transmission line comprising an optical fibre portion; an optical receiver adapted to receive the optical signal in the p...

A petroleum fraction, for example catalytic gasoline, containing aromatics and olefins, is upgraded by contacting the fraction with a solid catalyst under conditions to alkylate aromatics in the fraction with olefins in the fraction. The process reduces the olefin content and decreases the octane number sensitivity of the fraction. Benzene content may also be reduced.

L'invention concerne les glucuronyl-arabinarates. L'invention concerne également un procédé d'obtention de ces glucuronyl-arabinarates, consistant - dans une première étape, à procéder à la dégradation alcaline oxydative d'un hydrolysat d'amidon de manière à obtenir des glucosyl-arabinonates, - dans une deuxième étape, à procéder à l'oxydation sélective de tout ou partie des fonctions alcools prim...

L'invention concerne un procédé perfectionné d'oxydation alcaline et en milieu aqueux de sucres possédant une ou plusieurs fonctions alcools primaires à l'aide d'hypohalites et en présence d'un catalyseur constitué par un nitroxyl alcyle binaire ou tertiaire. Le procédé est remarquable en ce que l'oxydation se déroule en présence de concentrations élevées de sucres. Les produits obtenus par le pro...

In accordance with the principles of the invention, a surveillance radar is provided with a rotating, frequency squinting, end-fed slotted array antenna, which is caused to transmit a plurality of different carrier frequency pulses for successively illuminating specific antenna beam positions during rotation of the antenna. Upon reception of each radar signal return, a signal processor responsive ...

Disclosed is a method for the pyrolytic preparation of transmission-reducing layers consisting of antimony oxide-doped tin oxide onto glass and glass ceramics, where the antimony oxide-doped tin oxide layer contains tin and antimony in a molar ratio of 1:0.2 to 1:0.5.

A belt accumulation conveyor includes at least one driven endless conveying member defining a conveying surface and at least one brake surface lateral of the endless conveying member.
