A digital television system receives transmitted television information in the form of a stream digital packets representing video and audio information in compressed form. A packet transport unit (1507) routes the digital packets to respective digital video and audio signal processing sections according to header information contained in the packets. The digital processing sections (1511,1513) de...

Process which comprises reacting sucrose with a di(hydrocarbyl)tin oxide in an inert organic reaction vehicle with removal of water for a period of time and at a temperature sufficient to produce a 1,3-di-(6-O-sucrose)-1,1,3,3-tetra(hydrocarbyl)distannoxane.

An electrically conducting filter medium (20) is cleaned in situ by applying, at intervals, a brief voltage pulse between the medium (20) and a counter electrode (18) so the process liquid undergoes electrolysis. The cleaning process is significantly improved by occasionally applying a voltage of reverse polarity. For example a 5 second cleaning pulse making the filter medium (20) cathodic might b...

An apparatus for producing tubular articles, in particular for packaging tubes, from a film tape (48) which consists of weldable plastic and the longitudinal edges of which are thermally joined to one another, has a mould strap (46) which interacts with mould rollers (59, 60) and moulds the film tape (48) around a mandrel (45) to form a tubular article, a lower driven conveyor belt (20), running i...

The policing device verifies at a predetermined location of a communication system whether a cell stream transmitted over that communication system satisfies a negotiated cell interarrival time and a negotiated cell delay variation and takes adequate actions. The verification is performed according to an algorithm including the steps of comparing for each cell of the cell stream and at the predete...

Roller skate with improved comfort including dampers for damping only the forces that are applied to the wheels along axes that are not at right angles to the frame. It is thus possible to improve foot comfort while maintaining optimum transmission of the efforts of the foot to the wheels.

A loop-and-pintle seam in a paper-processing belt (72) having a polymeric-resin coating (68) is closed by covering the seam on the uncoated side with an encapsulating material, so that the seam area (50) has compression properties substantially identical to those of the remainder of the belt. After installing the belt (72) and closing the pin seam with a pintle (76), the seam region (50) is impreg...

Methods for closing a seam in a paper processing belt having a coating of polymeric resin material require the covering of the seam on the uncoated side of the belt with an encapsulating material, so that the seam will have compression properties substantially identical to those of use of the remainder of the belt. In one method, a viscous paste obtained by mixing a polymeric resin material with a...

A method and apparatus for handling and dry quenching coke comprises a coke box (10) for receiving and dry cooling a coke charge from a coke oven in a pollution-free manner and a self-propoelled carrier vehicle (12) having four-wheel steering capability for transporting the coke box. The carrier vehicle includes a lower main frame (16) and an upper tilt frame (14) for supporting the coke box and b...

Cyclohexenone oxime ethers of the general formula I in which the substituents have the following meanings: R<1> is alkyl; X is halogen; n is 1 to 5; R<2> is alkoxyalkyl or alkylthioalkyl; optionally substituted cycloalkyl or cycloalkenyl, an optionally substituted 5-membered saturated heterocycle having one or two oxygen and/or sulphur atoms as hetero atoms, an optionally su...
