Patent GB-1108544-A (GB)
Title: Water dispersible polyglycidyl ethers
IPC: D21H17/52
Filed: 1965-03-09
Abstract: Polyglycidyl ethers derived from polyphenolic ethers of polyethylene glycols and having the general formula <FORM:1108544/C3/1> in which n is a number from 4 to 45 form dispersions in water without the use of emulsifying agents.  The dispersions may also contain a curing agent for the epoxy resin.  These may be water dispersible nitrogeneous bases, e.g. alkylene diamines or polyamines or a bisalkarylamine. A preferred amine contains a fully fluorinated alkyl group distal to a primary amine group. Such a compound may have the formula RfR2NH2 in which Rf represents a perfluoroalkyl group having 4 to 12 carbon atoms and R2 is an alkylene group containing 1 to 12 carbon atoms. R2 may also be one or more divalent radicals selected from: aralkylene radicals having 8 carbon atoms, oxa radicals, unsubstituted aza radicals, carbonamido radicals, unalkylated - or N-alkyl-sulphonamido radicals. At least one of the radicals is an alkylene radical, not more than one radical is aralkylene, not more than two radicals are amide linkages and in the case of a sulphonamide linkage the sulphur is distal to the primary amine group. The compositions may additionally contain a catalyst, e.g. a metal fluoroborate together with adjuvantss and fillers.  The compositions may be used for treating fibrous materials, e.g. paper.ALSO:Fibrous materials, e.g. paper and cotton are treated with an aqueous dispersion of a glycidyl ether derived from a polyethylene glycol having the general formula:  <FORM:1108544/D1-D2/1> in which n is a number from 4 to 45 and which is formed without the use of an emulsifying agent.  The dispersion may also contain a curing agent for the epoxy resin which may be a water dispersible nitrogeneous base especially an alkylene diamine or polyamine or a bisalkarylamine.  Preferred amines contain a fully fluorinated alkyl group distal to a primary amine group and which may be separated therefrom with a divalent radical which may be a C1-12 alkylene radical and/or an unsubstituted or N-alkylsulphonamido group. Examples relate to the use of such dispersions as coatings for paper or preferably as beater additives.  In the latter case sheets are either formed by hand or using a Four-drinier machine.  The resultant treated paper shows resistance to mineral and vegetable oils.  Other examples relate to the use of dispersions of the invention as impregnants for cotton cloth to which they impart improved hand and crease resistance.

Title: Improvements in the manufacture and production of hydrocarbons which are saturated with hydrogen
IPC: C10G65/08
Filed: 1929-04-02
Abstract: 333,511. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). April 2, 1929. Mineral and tar oils, purifying &c.-Crude unsaturated hydrocarbons are converted into saturated hydrocarbons by treatment with hydrogen in two stages; in the first stage catalysts containing oxides or sulphides of metals of the second to the seventh groups are used, preferably in conjunction with metals of the eighth group or heavy metals of the first group, and the treatment. is continued until oxygen, sulphur, nitrogen and halogen compounds, and resinifying substances present as impurities in the raw materials are rendered non-injurious; in the second stage the purified hydrocarbons are hydrogenated in the presence of hydrogenating catalysts. A portion of the hydrocarbons may also be hydrogenated in the first stage. The first stage of treatment may be effected at 300-360‹ C., and the catalysts preferably contain compounds of metals of the sixth group, mixtures of the oxides or sulphides of molybdenum or tungsten and nickel or cobalt being specified. The hydrogenating catalysts used in the second stage are preferably activated by the addition of compounds of metals of the second to the seventh groups. The catalysts in both stages may be deposited on carriers having a large surface such as Florida earth, fuller's earth, or silica gel. Examples are given of the treatment of solvent naphtha, a fraction of the product of destructive distillation of brown coal, a gas oil, naphthalene, and anthracene.
Patent GB-426683-A (GB)
Title: Improvements in and relating to the application of ink or the like in printing machines
IPC: B41L1/00
Filed: 1934-04-04
Abstract: 426,683. Carbon papers; printing. SUPLIGEAU, C. L. H., 76, Avenue Pierre Larousse, Malakoff, and GUYOT, R. R. J., 34, Rue de Clamart, Chatillon-sur-Bagneux, both in Seine, France. April 4, 1934, Nos. 10212 and 10213. Convention dates, April 4, 1933 and July 6, 1933. [Classes 100 (ii) and 100 (iv)] In a method of applying ink, particularly copying ink as used for carbon papers, to determined discrete areas on one or both surfaces of a support such as paper, a clichÚ is used which is adapted to be displaced in relation to the support so as to produce a sliding between the clichÚ and the support at the zone of contact between them. The clichÚ may be in intaglio or relief, and may be secured to a cylinder, or engraved &c. in an envelope adapted to surround a cylinder, and the cylinder may be rotated so that the clichÚ has peripheral speed which is faster or slower than that of the speed of translation of the paper or other support, the size of the clichÚ being correspondingly modified. The cylinder may co-operate with an adjustable pressure cylinder which may either be positively driven or driven by the support. Printed sheets with discrete copying areas on the back may be produced in one continuous operation in an ordinary printing- machine with the addition of means for applying the copying areas. Where the ink or composition employed is solid in the cold state, the machine is provided with heating means for the ink and cooling means for the finished sheets to prevent penetration of the sheets by the ink. The clichÚ may consist of a sheet of copper engraved, preferably by the heliographic process or by milling, with a screened design consisting preferably of two sets of perpendicular lines; the screened design may also be produced by a photographic method. Where fine parallel lines are arranged on a curved clichÚ attached to a cylinder and parallel to the direction of sliding, these lines are partially blocked at intervals to prevent the ink from being forced too readily along the length of the lines when a doctor blade is sliding in contact with the clichÚ. The clichÚ, when on an envelope surrounding a cylinder, may be produced by electrodeposition. In a modification, the clichÚ is a patterned roller which transfers ink to an intermediate rubber roller driven at the same peripheral speed as the inking-roller, but adapted to slip in relation to the paper or other support on which it deposits the ink. The Specification as open to inspection under Sect. 91 states that a flat clichÚ may be used, and also that the sliding between a clichÚ and a paper or other support may be produced during a portion only of the time during which there is contact between the clichÚ and the support. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to vacuum tube amplifiers
IPC: B64C3/54
Filed: 1935-04-03
Abstract: 441,521. Transmission systems. HAZELTINE CORPORATION, 15, Exchange Place, Jersey City, New Jersey, U.S.A.-(Assignees of Case, N. P.; 38, 208th Street, Bayside, New York, U.S.A.) April 3, 1935, No. 10411. Convention date, Aug. 4, 1934. [Class 40 (iv)] [See also Group XL] In an amplifying system the ratio of the amplification of one band of frequencies to that of another band is automatically varied as the general amplitude varies, particularly for tone compensation in a low frequency amplifier. In one embodiment, Fig. 4, an amplifying system for speech frequencies comprises valves V1, V2, V4, V5 and a supplementary amplifier V3, which is fed with signals, in which the lower frequencies preponderate, from a filter R2, C4, C5 connected in the output circuit of valve V1. The gain of valve V3 is rendered inversely proportional to the output amplitude of the system by feeding energy from a potential divider P2 connected across one half of the output transformer T2 through condenser C3 to the diode rectifier contained in valve V2 and using the D.C. component of the voltage in its load resistance R1 to control the grid bias of valve V3 through a filter R7, R8, C7. The outputs of valves V2, V3 are fed in parallel to the grid of valve V4. The value of the capacity C3 is preferably chosen so that the control is dependent more on the amplitudes of the higher frequencies in the output and the time constant of the filter R7, R8, C7 is so chosen as to respond to variations in the amplitude of a normal musical passage but not to the variations in a single musical note. In a second embodiment, Fig. 5, the control valve V3 acts as a variable resistance in the screen grid circuit of valve V1 which also contains a frequency discriminating network C, R, L, the amplification of the middle register being thus caused to decrease when the general amplitude decreases and the resistance of the valve V3 is diminished. In a further embodiment, Fig. 6, the control valve V3 acts as a variable resistance associated with a low pass filter L, C8, C9 coupling valves V1, V4 and altering the pass characteristics thereof in accordance with the general level of the output.

Title: Improvements in or relating to the production of alcohols from olefines
IPC: C07C29/04
Filed: 1939-04-04
Abstract: 527,316. Alcohols. DU PONT DE NEMOURS & CO., E. I. April 4, 1939. No. 10535. Convention date, April 5, 1938. [Class 2 (iii)] In a process for the production of alcohols by the direct catalytic hydration of olefines in the presence of an aqueous solution of a mineral acid, e.g. sulphuric acid, a dilute alkaline solution is introduced into the alcoholic vapours leaving the reaction zone in such proportion that the crude condensate obtained on cooling the vapours has a pH value not substantially lower than 6.0. Corrosion of the apparatus by the crude products is thereby prevented, and undesirable impurities are removed. The process is particularly applicable to the production of ethyl and isopropyl alcohols from ethylene and propylene. In the plant shown, ethylene, compressed by a pump 2, is passed from a pipe 1 to a pipe 4, where it is mixed with water from pipe 20 and with recirculated ethylene from pipe 19. The mixture then passes through section 5 of a heat exchanger 6, where it is heated by the hot reaction products passing countercurrent through the section 12 of the heat exchanger. Additional heat is supplied by a heater 8, and the mixture of ethylene and water vapour passes to the reaction chamber 10, where it comes into contact with aqueous sulphuric acid. The reaction products pass from the chamber 10 through pipe 11, where they are mixed with dilute alkali solution from a tank 28, and then through section 12 of the heat exchanger to a water cooler 14, from which the unreacted ethylene and condensate pass to a high pressure separator 16. The ethylene is returned to the process through pipes 17 and 19, and the condensate passes through pipe 17A and valve 23, where the pressure is reduced to atmospheric, to a low pressure separator 25. The gas released in the latter is chiefly ethylene, and may be removed through pipe 27, purified and returned to the hydration process. The crude condensate is withdrawn through pipe 26 and rectified.
