Filed: 1968-05-16
Abstract: 1,196,872. Selective signalling. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 16 May, 1968 [19 May, 1967], No. 23369/68. Heading G4H. In a system in which n multi-cathode digit indicator tubes B 1 , B 2  . . . are set sequentially by digit signals received serially from a source M, each digit being represented by a single marking on one of a plurality of leads L 1 , L 2  - - - a capacitor/diode combination C 11 , G 11 ; is provided for each cathode to function as a temporary store for the cathode, whereby each tube is actually always glowing except for a period of 1/nth of each cycle during which the tube is set to display a desired digit. In operation positive clock pulses are applied A 1 . A 2  . . . sequentially to the lower plates of the capacitors. This results in the capacitors being discharged via their associated diodes. To cause a selected cathode to grow a negative digit pulse has to be applied to the upper plate of the associated capacitor via its diode simultaneously with a positive clock-pulse to its lower plate. This results in sufficient charge being left on the capacitor when the pulses terminate (and the charge cannot leak away because of the diode) for the cathode to glow, and to remain glowing until the next clock cycle. A negative digit pulse applied to a capacitor in the absence of a simultaneous positive clock pulse has no effect.

Abstract: A liquid hydrocarbon composition having a reduced tendency to permeate cellulose materials, e.g. Manila paper gaskets, contains an organic phosphorus compound P(X)a(XH)b (XR)c(R)d(H)e, where X is oxygen or sulphur; R is a monovalent C1-24 organic radical; a is 0, 1 or 2; b is 0 or 1; c, d are whole numbers from 0 to 5 and c + d is at least 1; e is a whole number from 0 to 4; and Za + b + c + d + e is 3 or 5; and a hydrocarbyl polysiloxane having a hydrocarbyl/silicon ratio of 1.7 to 3 : 1, the ratio by weight of phosphorus compound to polysiloxane being from 10 : 1 to 1000 : 1.  Preferably the liquid hydrocarbon contains by weight 0.001 to 1 per cent of the phosphorus compound and 0.00001 to 0.05 per cent of the polysiloxane.  The phosphorus compound may be a phosphine, phosphine oxide, phosphorane, phosphite, phosphonite, phosphinite, phosphenite, phosphate, phosphonate, phosphinate, phosphenate or a phosphorane-mono-, di-, tri-, tetr- or pent-oate.  Typical examples are pentaphenylphosphorane; dixylyl phosphite; diphenyl cresylphosphonite; diphenylphosphinic acid; ethyl dimethylthiophosphinite; tricresyl, tris (3 : 3 : 5-trimethylcyclohexyl), trifurfuryl and trithienyl phosphates; triamyl thionophosphate propyl dicresyl thiolophosphate; and methyltriethylphosphoranoic acid.  The polysiloxanes are either "silicone fluids," i.e. straight-chain linear compounds having terminal silicon atoms to which are attached three hydrocarbyl groups while each of the other silicon atoms bears two hydrocarbyl groups or unbranched cyclic polysiloxanes, or partially condensed silicone resins.  In examples relating to gasoline, kerosene and diesel fuels, there are disclosed the combination of dimethylpolysiloxane fluid with tricresyl phosphate, diphenyl cresyl phosphate, tributyl phosphate, tris (3 : 5 : 5 trimethylcyclohexyl) phosphine, or tributyl phosphite; methylphenyl polysiloxane fluid, containing 1.5 methyl groups and 0.5 phenyl groups per silicon atom, with di (2-ethylhexyl) 2-ethylhexylphosphonate; and a partially-condensed methyl silicone resin having a methyl/silicon ratio of 1.8 with triphenyl phosphate.  A specific gasoline composition to which tricresyl phosphate and a dimethyl polysiloxane are added contains small amounts of tetraethyl lead, N : N1-di-sec. butylparaphenylene diamine, disalicylalpropylene diamine, ethylene dichloride, ethylene dibromide, and a dye.  Reference is made to the addition of the organic phosphorus compounds and the polysiloxanes used in the invention to benzene, naphtha as used in paints and varnishes, Stoddard solvent, and xylene.

[Class 37.] In electrolytic cells for making conductivity measurements, the electrodes are substantially cylindrical and are maintained in fixed relationship with one another and the walls of the container by securing them to a rigid immersion member, or members, carried by a stopper which registers accurately with the mouth of the container. In the construction of Fig. 1, electrodes F, F1 are sealed to a glass or quartz rod G and into the ends of glass or quartz immersion members D, E carried by a stopper C ground into the mouth of the container A. Connection with external leads, O, O1 is made by filling the immersion members D, E with mercury. In modified constructions, cylindrical electrodes surround immersion members which are sealed together at their lower ends or a single twin-bore immersion member, and connection is made with the electrodes by threading wires through the bores of the immersion members, or, by filling the bores with mercury and providing openings or rivets (as at K, Fig. 9) through the walls of the immersion members under the electrodes. In the construction of Fig. 9, one electrode F surrounds the outer bore of a concentric twin-bore immersionmember, whilst the other electrode F, surrounds an extension L of the inner bore. The electrode may be formed of strip metal or by depositing a metallic coating on the immersion member(s) in known manner, such as by electro-chemical or sputtering methods or by the use of metallic paints.

Title: Process for treating fibrous materials
IPC: D06P1/642
Filed: 1929-08-08
Abstract: 317,019. Soc. of Chemical Industry in Basle. Aug. 8, 1928, [Convention date]. Yarns, treating with liquids.-The dyeing properties of fibrous materials of animal or vegetable origin are modified by treating the fibres in loose or worked up condition with an isocyanate of the formula R-N=C=O, where R is any organic radicle, in the presence or absence of an acid or alkaline catalyst, such as zinc chloride or pyridine, and in the presence or absence of a diluent, the treatment being discontinued while the structure of the material remains unchanged. Under this treatment, wool loses its affinity for acid wool dyes, and cotton is rendered immune to substantive dyes, while it is easily dyed by acetate silk dyes, such as insoluble azo dyes and aminoanthraquinones. Any aliphatic or aromatic isocyanate may be employed in the treatment, phenyl, naphthyl, and nitrophenyl isocyanates being specified. The products may be woven with untreated yarns to obtain effects by subsequent dyeing or printing. Such effects may also be obtained by treating piece goods locally with an isocyanate. In examples, (1) cotton yarn, which has been dried in a vacuum, is heated with phenylisocyanate containing a little pyridine, the excess of isocyanate is distilled off in a vacuum, and the yarn washed with hot alcohol to remove pyridine and some diphenylurea which has been formed; the treated yarn ie externally unchanged, but shows increased weight and contains nitrogen, it is strongly dyed by basic dyes without a mordant and by acetate silk dyes, but is scarcely affected by substantive dyes, (2) cotton yarn is immersed in phenylisocyanate and pyridine for several days, the subsequent treatment being as in the preceding example, (3) woollen yarn saturated with an equal weight of phenylisocyanate is heated for two days on the water-bath with exclusion of moisture and is then boiled with alcohol; the product shows unaltered structure but a considerable increase in weight and is no longer dyed by acid wool dyes, (4) cotton, treated as in example 1, is mixed with untreated cotton and dyed in a bath containing brilliant blue 6B and glaubers salt; the untreated cotton is dyed blue, while the treated fibres remain nearly white, (5) cotton, treated as in example 1, is dyed a powerful red-violet shade in a bath containing 1 :4-diaminoanthraquinone in fine suspension and soap; untreated cotton is not dyed by this process, (6) cotton, treated as in example 1, is dyed green in a bath containind Solid green and acetic acid, and (7) wool, treated as in example 3, remains undyed when, in admixture with untreated wool, it is introduced into a dye-bath containing p-aminoacetanilide # acetyl-H-acid, glaubers salt and sulphuric acid; the untreated wool is dyed a deep blue red. Specification 130,277, [Class 2 (ii), Cellulose &c.], is referred to.
