Title: Improvements in the treatment of ramie and like textile fibres
IPC: D01C1/02
Filed: 1947-12-31
Abstract: 683,602. Treatment of ramie and like textile fibres. DUHAMEL, E. C. Dec. 31, 1947 [March 16, 1943; March 16, 1943], Nos. 35290/47 and 35291/47. Drawings to Specification. Class 120(i) A method of treating ramie and like textile fibres comprises passing strips of raw bast fibres produced by the scutching of the raw stems in a continuous sliver-like bundle through a large number of baths in succession and applying pressure to the said bundle as it emerges from each bath, the earlier baths containing chemical solutions for degumming and the later baths water for washing away any article which may still be adhering to the strips of raw bast fibres after scutching. To form the sliver-like bundle of raw fibres the raw stems are fed on to a moving belt and through a funnel so as to bring them together. At the exit of the funnel there is provided either means for placing rubber bands around the bundle or means for wrapping a roving around the bundle in the form of an open helix. The sliver-like bundle so formed is then fed to a series of vats each divided up into a number of baths containing solutions, of gradually increasing strengths, of the particular chemical being used for degumming. In passing from one bath to the next the sliver-like bundle passes between two rollers, which are preferably fluted, the upper roller being weighted. The liquid squeezed out of the sliver-like bundle by the action of the rollers is guided by a suitable spout into the bath preceding the one from which the sliver-like bundle has come. Preferably caustic soda is use for the degumming operation and arrangements may be made to heat the chemical solutions in the baths by a steam coil. In addition to or in substitution for the caustic soda treatment, an acid, sodium carbonate, a soap or a sulphonate of fatty alcohols, or a hypochlorate followed by hydrogen peroxide may be used with the interposition of washings and finally the fibres may receive a coating of a fatty emulsion.

Title: Hexahydrobenzoate of 19-nor-testosterone
IPC: C07J1/00
Filed: 1956-11-20
Abstract: The invention comprises the hexahydrobenzoate of 19-nor-testosterone and the preparation thereof by condensing in the presence of a condensation agent a hexahydrobenzoyl halide, hexahydrobenzoic acid or hexahydrobenzoic acid anhydride with 19-nor-testosterone, the condensation being effected in solution. The condensation agent may be a substance capable of taking up hydrogen halide, e.g. a tertiary organic base such as pyridine, particularly when a hexahydrobenzoyl halide is used in the condensation.  A suitable reaction temperature is in the range of from 10 DEG  to 35 DEG  C.  The above process may be modified in that a known intermediate compound occurring in the production of 19-nor-testosterone, said intermediate having a free hydroxy group in the 17-position, is hexahydrobenzoylated by condensation with a hexahydrobenzoyl halide, hexahydrobenzoic acid or its anhydride, and the resulting 17-hexahydrobenzoylated derivative is converted to the hexahydrobenzoate of 19-nor-testosterone by known methods. One detailed example is given.

Title: Adaptive networks
IPC: G06F7/02
Filed: 1971-07-30
Abstract: 1402093 Trainable circuits NATIONAL  RESEARCH DEVELOPMENT CORP 29 Sept 1972 [30 July 1971] 36006/71 Heading G4R A learning circuit which can be taught to recognize certain signal patterns comprises a number of bit-addressed stores to all of which the patterns are applied. In a "learn" mode the output resulting from the application of a signal pattern is modified, the modified signal being fed back to the stores to adapt the circuit to respond to different patterns, in the "use" mode, by providing different outputs. The embodiment illustrated uses four stores 10-13. Each comprises 8 bi-stables. A 3-bit signal pattern applied at 14-16 selects one bi-stable in each store, resulting in a 4-bit output number at 17-20. During the learn mode the 4-bit output is passed to unit 22 which adds or subtracts one, the result being set up on the selected bi-stables. The command to add or subtract accompanies the pattern to be learned, and depends upon to which of two significant classes the pattern belongs. By applying to the circuit several times a certain class 1 pattern and a certain class 2 pattern the circuit adapts to provide 4-bit output numbers for these patterns which are respectively high and low. In the use mode the unit 22 is not used. If a pattern applied to the circuit results in a high output number it is likely to be a frequent class 1 pattern, where as a low output number shows it is likely to be a frequent class 2 number. A number between these extremes shows that the pattern is a less frequent pattern of either or neither class.
