A package of tape is formed with flanged portions built up at the ends and a central helical traverse portion. The flanged portions are effectively formed by a plurality of separate spiral windings each of which is interlocked with each other and the central traverse portion. The central portion is formed from a plurality of helical traverses with reversal positions slightly inside the inner edge ...

The wound body or package comprises a band or tape or the like which is wound thereon in the form of parallel windings or layers. At the central region of the wound package there is arranged a continuous or through-passing axial opening which is bounded by an inner winding layer of the wound band or tape. This inner winding layer together with the neighboring winding layers form a support body for...

A coating and/or moulding composition for preparing articles exhibiting heat-, fire- and corrosion- barrier properties comprises (a) a water-insoluble particulate inorganic material, preferably a layer mineral, (b) a water-solubilised inorganic binder, preferably a phosphate, (c) an aqueous medium, and (d) optionally an organic polymer, preferably a water-insoluble polymer, components (a) and (b...

The spring mattress is intended to be covered by a mattress and comprises a fixed part and, on the side of the head, a raisable movable part. Its movable part (6-7) is joined to its fixed part (1-3) by two sets of small rods which are each arranged on a side of the spring mattress, each of these two sets consisting of two small rods (10 and 13) forming an articulated quadrilateral with the fixed a...

To allow efficient combustion of gas, the gas is premixed with a controlled quantity and then passed into the hollow interior of a gas burner (40) whence it passes through the small apertures in the burner to a combustion chamber (38) where the mixture burns. The apertures in the gas burner are sized so no flashback from the combustion chamber occurs. The combustion chamber (38) is immersed in a t...

Pyrazolo[3,4,5-kl]acridines are described as antibacterial agents and antitumor agents as well as pharmaceutical compositions and methods for their preparation.
