The method comprises heating a synthetic resin sheet to the softening temperature, superposing the sheets by a pattern mould produced by electroforming so as to have a sheet superposing surface having an infinite number of fine vaccum pores, and vaccumsucking the sheet on the superposing surface through the pores and then transferring the patterned corrugation on the surface of the synthetic resin...

Sugars and partly protected sugar derivatives are chlorinated by reaction of unprotected hydroxyl groups with thionyl chloride to form a persulphite followed by decomposition of the sulphite groups to form chlorosulphites, displacement of the chlorosulphite groups and insertion of chlorine atoms at one or more positions, characterised in that formation and displacement of the chlorosulphite groups...

The data are fault-tolerant, the memory controller (St0, St1) is doubled. Except the address and control signals, only the write data are forwarded by the one memory controller, and only the control data are forwarded by the other memory controller, and in the first case are written into the user data part (SPN) of a two-part memory and in the second case are written into the control data part (SP...

A method for coating a glass container with a stabilized compsn. comprises heating the surface of the container to at least 800 F, and spraying a glass coating compsn. consisting of a monoalkyltin trihalide and 0.5-10 wt.% of a solubilizing material onto the heated surface. The solubilizing material is pref. mono- or dihydric alcohols, glycol ethers, esters, aldehydes formamides or acetals. The c...

Apparatus for forming a plastics coated metal tube comprising means for forming a continuous strip of metal into a U-shape and a forming sleeve for folding the strip into an overlapping tube. A mandrel (23) is also provided which extends through the forming sleeve and through a locating sleeve (30). The locating sleeve (30) centralises the tube as it passes over the mandrel and welding means are p...

A safety unit combining eye and hearing protection in which retention of earcups on the head of wearer is by resilience of separate side arms (10,26,112) carrying the earcups (28). The resilience is resisted by provision of a rigid frame to spectacles (12,112), or a rigid beam (30) to goggles (20). Snap fitting of arms to the frame or beam enables use of the arms with either spectacles or goggles....

This invention concerns fuel channels 30 designed for nuclear reactors. For a boiling reactor of the D-lattice type, a description is given of an improved arrangement and an improved procedure for installing a nuclear-fuel unit A1-A4. In particular, the upper and lower ends of a nuclear-fuel unit A1-A4 of the D-lattice type have been moved diagonally towards the cross-shaped intermediate space of ...

A vaccine comprises a non-cytopathogenic strain of bovine viral diarrhoea virus, grown in a bovine derived cell line such as MDBK and killed, for example with beta -propiolactone. The adjuvant is Quil A.

Toptical compsn. comprises (1) at least one topically-active pharmaceutical (I) and (2) hyaluronic acid (II), or one of its mol. fractions, opt. in the form of a salt with alkali or alkaline eart metals, Al, NH4 or with one or more active ingredients (esp. (I)). The pure Ba salts (A) of noninflammatory (II) fractions of mol.wts. 250000-350000; 50000-100000 or 500000-730000, free of (II) of mol.wt....

An apparatus for cutting scrap tires and other waste products is disclosed. The apparatus includes a frame having a cylindrical anvil roll rotatably mounted therein. A pair of blade rolls are also mounted in the frame for rotation about corresponding axes which are parallel to the rotational axis of the anvil roll, the blade rolls being angularly spaced from one another relative to the axis of the...

16-Phenoxy and 16-(o, m or p)-substd.-phenoxy prostaglandin derivs. of formula (I)[R=H and their pharmaceutically acceptable acid addn. salts are prepd. by hydrolyzing a cpd. of formula (II) with acid, and pref. converting to their nontoxical salts. In the formulas, R=H or lower alkyl or Me; X=H, halo, lower alkyl or lower alkoxy; breaked lines are each alpha or lower configuration; R'=ether-for...

Assembly has fuel rods (12) and guide tubes (16) held by spaced grids (14).
