Filed: 1974-05-17
Abstract: 1456755 Light guides INDUSTRIE PIRELLI SpA 17 May 1974 [23 May 1973] 22114/74 Heading G2J An optical fibre element 1 for a telecommunications cable comprises a plurality of optical fibres 4 disposed between two strips 2, 3 of a material, e.g. a thermoplastics material, which is relatively extensive compared with the fibres, each fibre extending in an undulating path to-and-fro across the strips without overlapping adjacent fibres, the strips being bonded together. The element may be made by passing the heated strips continuously between rollers and feeding the fibres through an oscillating comb between the strips, see Fig. 2 (not shown). Several elements may be wound round a wire core covered with a layer of thermoplastics material which, like the strips 2, 3, may be loaded with carbon black.

Title: Improvements in or relating to the stabilization of motor fuels
IPC: C10L1/22
Filed: 1935-08-07
Abstract: Motor fuel is stabilized against discoloration and gum formation by adding p-cyclohexylaminophenol.  The inhibitor may be added as a solution, e.g. in methanol or benzol, or the fuel may percolate through a mass of the inhibitor.  In an example, 0,001--0,006 per cent of inhibitor is added to benzol or to cracked petrol. Specification 350,438 is referred to.  According to the Specification as open to inspection under Sect. 91, the inhibitor may be a compound of the formulae HO--Ar--NHR, where Ar is a phenylene nucleus with or without alkyl substituents and R is a cyclohexyl nucleus with or without alkyl substituents. Examples Examples include: o- and m-cyclohexylaminophenols; o- and p-(2-methylcyclohexyl)-aminophenols; o-, m- and p-(4-methylcyclohexyl)-aminophenols; o- and p-(4-ethylcyclohexyl)-aminophenols; the 4-cyclohexylaminoderivatives of 2-methyl-, of 3-methyl-, of 2-ethyl-, and of 2.5-dimethylphenols; the 3-cyclohexylaminoderivatives of 5-methyl-and of 2 : 4-dimethyl phenols.  The induction period of petrols containing 0,0015 per cent in each case of three of these inhibitors is compared with that of the petrol and also with that of the petrol containing the same amounts of p-benzylaminophenol.  This subject-matter does not appear in the Specification as accepted.

Patent GB-1565190-A (GB)
Title: Recombinant dna transfer vector and microorganism containing a gene from a higher organism
IPC: C12N1/16
Filed: 1978-05-25
Abstract: DNA transfer vectors which contain in their nucleotide sequence a subsequence which has the structure of the gene of a higher organism and which has been produced by a transcription on a gene of the higher organism are described. For example, this gene can encode the A chain or the B chain of human insulin or else be a gene which encodes the growth hormone of a higher organism. The DNA transfer vector is prepared by isolating from cells an mRNA which encodes the desired protein, specifically essentially free of proteins, DNA and other RNA. Then a double-stranded cDNA is synthesised, in which one strand has a nucleotide sequence which is complementary to that of the mRNA, in this way a cDNA is obtained which has a nucleotide sequence which encodes the desired protein. A DNA transfer vector with reactive ends is linked to the double-stranded cDNA, resulting in the desired DNA transfer vector. The DNA transfer vectors can be used to modify microorganisms which then contain a nucleotide sequence having the structure of a gene of a higher organism.

Abstract: 781,820. Grinding springs. MARQUETTE METAL PRODUCTS CO. Aug. 10, 1955, No. 23064/55. Class 60. [Also in Groups XXIV, XXXII and XXXIV] A method of producing a helical spring for clutches (see Group XXIV) and brakes, from a single piece of metal stock of uniform crosssection, and so as to have a main coil portion 12 of one cross-section and a control coil portion 10 of reduced cross-section, comprises, coiling the stock to form a cylindrical blank, forcibly supporting the blank on relatively radially stepped respective peripheral surface portions of an arbor or collet (see upper half of Fig. 3), and removing metal from the control coil forming portions of the blank while so supported (as shown in lower half of Fig. 3). As shown, with the blank mounted in a collet 16, the metal is removed by grinding. The amount of stock removed is usually limited to the sub-surface peripheral portion of the spring in which the metal has been strained beyond its elastic limit. The diameter of the control coil portion 10, relative to the diameter of the portion 12, may however be controlled within a large range by the amount of stock removed. In a modification, centerless grinding is performed.
