Title: Improvements relating to the dyeing, printing or stencilling of cellulose acetate
IPC: D06P1/642
Filed: 1924-09-23
Abstract: The fastness to light of dyeings, printings, or stencillings on threads, yarns, fabrics, films, or other products made of or containing cellulose acetate, is improved by an after-treatment of the dyed, printed, or stencilled goods with one or more simple amino or substituted amino compounds, such as aniline, alkylanilines and alkylphenylene diamines, for example tetraethylphenylene diamines. The amines may be applied in aqueous solution in the form of the free base or soluble salt such as hydrochloride or they may be solubilized by pre-treatment with the solubilizing agents of Specifications 219,349, 224,925, 242,393, and 242,711.  It is preferred not to use amines which are susceptible to air oxidation such as diphenylamine, p-aminophenol and p-phenylene diamine.  The dyeings, printings, or stencillings may be produced by any of the ordinary processes or by the processes of the Specifications mentioned above, and the invention is particularly applicable to goods which have been coloured with azo dyes, such as benzeneazo-a -naphthylamine, benzeneazophenylmethylpyrazolone, and a -aminoazonaphthalene, or with quinophthalone.  An example shows the treatment of an acetylcellulose knitted fabric dyed with benzeneazo-a -naphthylamine with aqueous diethylaniline hydrochloride.

[Class 100 (ii).] The ink on printed sheets is dried or hardened to prevent offset, by placing a stack or roll of collected sheets in a confined space, creating a sub-atmospheric pressure about the stack &c. to permit the sheets to separate, and introducing an oxidizing-agent within the space. As shown, a roll 11 consisting of sheets rolled in a web of anti-offset material, is supported in bearings 21 in a casing 10, the lower half of which is cylindrical to reduce the air space, air is exhausted by means of a suction pump 13, a stop valve 16 is closed, and ozone is admitted through a valve 19 until the pressure is somewhat above one atmosphere. The roll is allowed to remain in the casing the required length of time, say overnight, the pump 13 is then used to withdraw the ozone, and air is admitted to facilitate raising a cover 12. In a modification, a stack of sheets interleaved with anti-offset sheets is placed in a rectangular casing.

Abstract: 1,221,692. Automatic temperature control systems. ELECTRO-OPTICAL INDUSTRIES, Inc. May 15, 1968 [May 15, 1967], No.23079/68. Heading G3R. A temperature control system having a four arm electrical bridge including a temperature dependent resistance heater has a predetermined bias current passed through the bridge at balance to compensate for normal energy losses. The bridge 12 has in one arm a heater 14, preferably of high resistance, and other resistors, arranged to minimize the heat losses, the diagonal of the bridge being connected to a differential D. C. amplifier 40 controlling a transistor 50 which is cut off when the bridge is balanced. In this condition current is passed through the bridge by way of a resistor 60 the value of which is arranged so the heater 14 provides for normal losses in the system or body which is being heated. In another arrangement Fig.2 (not shown) the bridge is fed with A.C. and bridge current is controlled by a saturable reactor, a saturable transformer, or a phase controlled thyristor arrangement which is adjusted so that when the bridge is balanced a current of sufficient magnitude is passed to the bridge to make up for normal losses. In a further arrangement Fig. 3 (not shown) an A.C. source (136) may be connected to the bridge for detection purposes and a D.C. source (134) provides heating current. In Fig. 5 (not shown) the functions of these sources are reversed, and in Figs.4 and 6 (not shown) the A.C. and D.C. sources are connected in series appropriate detection and current control devices being utilized in each case.

Title: Improvements in the manufacture and production of valuable gases and the like
IPC: C10G1/06
Filed: 1929-07-31
Abstract: 319,657. I. G. Farbenindustrie Akt.- Ges. Sept. 25, 1928, [Convention date]. Gaseous hydrocarbons are recovered from the gases containing large amounts of hydrogen produced in destructive hydrogenation processes after the products which are liquid at ordinary temperatures have been removed by subjecting the gases to strong cooling increased by stages or great compression increased by stages or both. The benzines and middle oils are removed from the gases leaving the reaction chamber by the employment of a washing oil under pressure. In this manner hydrocarbons such as butane, propane, and small quantities of ethane &c. are dissolved in the washing oil to such an extent that the undissolved gases can be used again without further treatment. By releasing the pressure on the washing oil most of the dissolved gases are set free and a gas mixture containing about 60 per cent of hydrogen and 40 per cent of hydrocarbons is obtained. This mixture is compressed in a poly-stage compressor up to a final pressure of 250 atmospheres. In stages 1 and 2, up to 3 and 9 atmospheres, chiefly pentane is obtained; in stage 3 at about 27 atmospheres butane is obtained, and in stages 4 and 5 at about 80 and 240 atmospheres propane is obtained. The residual gas contains about 10-20 per cent of hydrocarbons and by compressing to still greater pressures, or lower temperatures, the higher homologues of methane can be separated.

Abstract: 623,200. Shaft seals. ABBEY, A. (Jonkopings Mekaniska Werkstads Aktiebolag). Aug. 8, 1946, No. 23582. [Class 122(v)] In a shaft seal for centrifugal pumps for liquids and comprising a ring valve between the shaft 1, Fig. 1, and the pump 'casing formed of one member 6 fixed to the casing and another 10 fixed to the shaft, the one member 6 comprises a ring-shaped elastic plate around the shaft which is vertical and has a free edge below the other member 10 on which the edge is brought to bear by liquid pressure and/or its own resiliency on stopping the pump, and is similarly released therefrom on starting the pump. The valve plate 6 is secured at its outer edge by a bolt 7 to a casing plate 5 and carries at its inner free edge a tightening ring 9. In a modification the valve plate comprises a flat rubber ring secured at its inner edge to the shaft and bears at its outer edge against a fixed casing plate. Blades 3, 4, on a trap wheel 2 secured to the shaft 1, cause the liquid to form a seal against back pressure of vapour. When using corrosive liquids an oil seal against such vapours comprises a shute 21, Fig. 4, against which oil is pressed by a rotating wall 22 secured to the shaft 20. Vanes 25 ventilate a chamber 19 leading to an escape duct 24. At high working temperatures evaporation of pump liquid is avoided by the provision of water channels in the casing walls.
