The present invention regards a particularly quick-setting Portland cement clink er containing calcium fluoro-aluminate (11CaO7Al2O3CaF2) mixed with lime that has not undergone the burning process of the clinker.

The device comprises a food container having a funnel-shaped bottom with a funnel downwardly turned mouth connected to a portioning device. Underneath the portioning device is a shovel (16) connected to a spring (15). A motor-driven component (18) tensions and suddenly releases the spring to produce a catapult-type movement by the shovel.

A granulate useful in detergent formulations is disclosed, which comprises at least 10% by weight of polymer useful in such formulations and at least 20% by weight of at least one inorganic component which is also useful in such formulations. The granulate has a bulk density of at least 700 g/l, and possesses low hygroscopicity. A process formaking such a granulate is also disclosed.

The invention relates to compositions which cross-link to give elastomers and are based on component (A) comprising polyorganosiloxane (I) with at least two alkenyl groups per molecule and component (B) comprising polyorganosiloxane (II) with at least two silicon-bonded hydrogen atoms and organic per oxide (III).

A VSAT satellite communications network utilizes parallel concatenated coding on its inbound or outbound links, or both. For short data blocks, nonrecursive systematic tail-biting convolutional codes are used. For longer data blocks, recursive systematic convolutional codes are used. These parallel concatenated coding techniques are used in conjunction with spread-spectrum modulation to provide a ...

A packet radio system is provided with a multiple access scheme which operates to schedule transmissions of data bearing radio packets on a common communications channel from a plurality of users to a common receiver of the said system. The radio packets via which the plurality of users communicate include synchronisation data, and by providing the common receiver with a multi-user detector, conte...

There are provided a quantitative and simple method of determining telomerase activity and a method of detecting a telomerase positive cell, said methods comprising: (i) a step of conducting elongation reaction of telomerase substrate with telomerase in cells; (ii) a step of subjecting the resultant elongation reaction product to base binding chain reaction in cells; and (iii) a step of quantitati...

The mesophilic restriction endonuclease AvaI and its isoschizomers derived from Anabaena and Anabaenopsis have been found to support highly efficient amplificat ion of target nucleic acid sequences in thermophilic Strand Displacement Amplification (tSDA). The maximum amplification factors observed occurred at temperatures which were previ ously reported to result in reduced enzyme activity. As Ava...

New nitropyrazole esters of the formula , in which R1 represents C1-C6-alkyl, are prepared by nitration of the corresponding pyrazole esters. The nitropyrazol e esters permit the preparation of a known nitropyrazole amide in a particularly simple and economical manner and thereby improve the preparation of active compounds which are accessible from the nitropyrazole amide.

A motor-vehicle seat (1) comprising a vertically elongated and upwardly open lateral hollow body (5), arranged substantially at one side of the backrest (3) rearwardly of the seat cushion (2) and providing a stand receptacle for umbrellas (B) or similar articles.
