This invention relates to a method for charging a user of a computer system of the chargeable services used by him. So that the user could be charged for although he hasn't got a separate user identification the access to the chargeable services of the computer system (8) is offered to the user via his terminal (3) for the time period during which a connection from the user's telephone (5) to the ...

A method and apparatus are provided for communicating VBI user information for digital television. A syntax is provided which allows the transport of closed captions, non-realtime video, sampled video and AMOL. Non-realtime video can be used to transport various types of data, such as a vertical interval test signal (VITS) through the system at full resolution. The provision in the syntax of a ...

The invention relates to pharmaceutical preparations which are suitable for the treatment of inflammatory bowel disorders and contain at least one compound of the formula I (I) in which R1 is Ar, cycloalkyl having 3-7 C atoms or cyclo alkylalkyl having 4-8 C atoms, R R1 and R , R3 is H, OH, OA or A, R4 is A or phenyl which can optionally be mono or disubstituted by Hal, OH, OA, CF3, NO...

A MQW semiconductor Mach Zehnder phase modulator is formed by two Y-junctions (12, 32), each having a single waveguide (14) optically coupled with two branch waveguides (18, 20). The branch waveguides of the two Y-juntions are optically coupled in Mach-Zehnder configuration that, under zero bias conditions, has one interferometric arm longer than the other to provide a pi phase shift. The additi...

The surface-modified fillers according to the invention are manufactured by treating oxidic or siliceous fillers with a silane of the formula R1R2R3 Si - X1 - (- Sx - Y - )m - (- Sx - X2 - SiR1R2R3)n and are used for the manufacture of rubber vulcanizates, particularly tyres, with reduced dynamic damping and favourable abrasion behaviour.

A double wall lamp assembly adaptable to several types or configurations of small to medium size reading lamps, which basic designs and types of single wall construction have been in use for many years, however this invention has a very important difference in the design and construction details which offers inherent safety features not found in the lamps of the single wall basic designs and style...

The beam comprises waist section having at least one connector piece (30) made of material with lower thermal conductivity, e.g. plastics, than at least part of flanged sections (1,2) made of e.g. metal. The beam sections are held together by e.g. adhesive, snap-fit couplings or fasteners, or combination of these.

The box comprises at least one connector piece (30) provided in length side edge surfaces (3), containing material, e.g. plastics, with lower thermal conductivity than at least part of top and bottom sheets (1,2) made of e.g. metal. Connector pieces are secured to sheets by e.g. adhesive, snap-fit couplings or fasteners, or a combination of these.

Detecting leaks from nuclear fuel rods immersed in a liq. such as water in either a nuclear reactor that has been turned off or in another region at least partially filled with liq. comprises: sucking up the liq. around the rods, sepg. the gases from the removed liq. and feeding the gases into a measuring device in order to analyse any gaseous fission prods. present.The gaseous fission prods. are ...

The method determines transmitted and/or diffused light at temperatures below and above phase conversion in an alkyl ketene dimer sample of grist or back water, the difference between the two measurements is calculated. This difference amounts to the difference in turbidity (delta NTU). Turbidity is measured after removal of coarse fibres. The coarse fibres are removed by the addition of acid and ...

The measurement apparatus has a capacitor formed by a reference electrode (5) and a test electrode (9) provided for a specifically predetermined measurement temperature together with a periodically vibrating component (1) connected to at least one of the electrodes. The vibrating component has a maximum predetermined drive temp. In the capacitor a current is produced which is a dimension of the ex...
