Patent GB-733397-A (GB)
Title: Improvements in sensitized photographic emulsions and new dyes
IPC: C09B23/06
Filed: 1953-09-01
Abstract: Meso-p-hydroxyphenyl-carbocyanine dyes are described which have the following general formula <FORM:0733397/IV (c)/1> wherein R and R1 represent substituted or unsubstituted alkyl groups, X represents an anion and Z and Z1 complete heterocyclic nuclei of the benzthiazole, or naphthathiazole series.  R and R1 may be methyl, ethyl, n-propyl, isopropyl, n-butyl, iso-butyl, n-amyl, benzyl, b -phenylethyl, b -hydroxy ethyl or b -carbomethoxyethyl.  The dyes are made by condensing a compound of the formula <FORM:0733397/IV (c)/2> wherein X1 is a halogen atom, with a quaternary salt of the formula <FORM:0733397/IV (c)/3> wherein X2 is an anion, preferably in the presence of a basic condensing agent.  It is preferred to carry out the condensation in an inert diluent.  The first intermediate may be prepared as follows.  A compound of the formula <FORM:0733397/IV (c)/4> is heated with an acid halide of the formula <FORM:0733397/IV (c)/5> wherein R2 is alkyl, in the presence of pyridine or quinoline. The resulting p-alkoxy benzoyl derivative is hydrolysed to the corresponding p-hydroxybenzoyl derivative which is then heated with phosphorus oxyhalide, as described in Specification 533,425. Specification 676,164, [Group XX], also is referred to.

Title: Nylon phenolic resin fibres
IPC: C08L77/00
Filed: 1972-05-23
Abstract: 1388177 Nylon modified phenolic resin fibres CARBORUNDUM CO 23 May 1972 [1 June 1971] 24097/72 Heading B5B [Also in Division C3] Fibres are made by melt spinning an uncured phenolic resin, preferably a novolac, in which is incorporated, prior to spinning, 5 to 30%, preferably 10%, of an aliphatic nylon. The nylon may be incorporated by dissolving it in a melt of the phenolic resin, or by dissolving the phenolic resin and the nylon in a mutual solvent and thereafter removing the solvent. The fusible uncured phenolic resin fibre so made may be cured, at least to the point of infusibility. In examples, from 5 to 20% of nylon 610, or 10% of nylon 6, or of nylon 6,6, or of nylon 6,12, or 10% of a mixture of nylons 6, 66, and 6,10 is added to a novolac resin of number average molecular weight 700, made in known manner, addition being effected by dissolving the nylon in the molten phenolic resin. Melt spinning is effected at 127 C. Curing of the fibres is carried out by immersing the spool of uncured fibres in an aqueous solution of formaldehyde and hydrochloric acid, which is gradually heated to the boiling point. The fibres are water washed and dried in air at 60% to yield infusible cured phenolic resin fibres with an average tenacity of 1À7 g/den. and an elongation at break of up to 45%.

Title: Intermediate drive for conveyors having adjacent conveying and return runs
IPC: B65G23/00
Filed: 1957-08-02
Abstract: 870,858. Driving-apparatus for belt conveyers. GEWERKSCHAFT EISENHUTTE WESTFALIA. Aug. 2, 1957 [Aug. 13, 1956], No. 24604/57. Class 78 (1). A conveyer belt or endless traction member supporting the belt is driven at a position between the ends of the conveyer by a driveunit which acts on both the conveying and return runs, the arrangement being such that when the conveyer is inclined, the return run is braked and the energy absorbed by the braking means is transferred to the conveying run to assist in driving the latter. As shown, motor 10 drives shaft 9 which through gearing 11-14 and wheel 15 drives ascending conveying run 16. Wheel 20 engaging the return run transfers energy from the descending return run 18 via gearing 21, 22 and 23, 24 of which 23, 24 is of higher ratio than gearing 11, 12, thence via friction clutch 26 to the shaft 9. The clutch 26 has pressure-plates which are acted on by a spring 28 adjustable so that the clutch can slip but transmits a torque equivalent to nearly the full weight of the return run in doing so. In order to achieve a corresponding transfer of energy from the conveying run to the return run when the conveying run is travelling downwardly a further pair of gears 32, 33 is provided of lower ratio than the gears 11, 12, these being brought into use in place of gears 23, 24 by disconnecting clutch 34 and engaging a similar clutch 35. The clutches 34, 35 may be of the free-wheel type or as shown. The ratio of gears 23, 24 may be chosen such that the conveyer when arranged in a horizontal plane operates with the stresses in the return run increased to match correspondingly reduced stresses in the conveying run.
