Title: Improvements in processes for the hydrolysis of organic esters of cellulose
IPC: C08B3/24
Filed: 1932-05-06
Abstract: Loss of strength during the saponification of filaments, yarns, fabrics, and other materials made of cellulose acetate or other organic esters of cellulose, is avoided by the use of saponifying media containing oils.  The oils used may be of mineral, vegetable or animal character; or soluble oils such as sulphonated castor oil &c. may be employed.  The insoluble oils may be emulsified in aqueous saponifying media, such emulsification being assisted, if desired, by emulsifying agents, the use of soaps of inorganic or organic bases being particularly advantageous in this connection since these also exert a desirable buffer effect on the saponification reaction. Alcoholic or aqueous alcoholic saponifying media may also be used, and with alcoholic media the amount of alkali present may be, as described in Specifications 125,153 and 313,404, [both in Class 2 (ii), Cellulose &c.], less than that theoretically necessary.  The saponifying agent may be caustic alkali, an alkaline salt or an organic body such as an amine or an hydroxy amine; the concentration of the saponifying agent, the temperature of the saponifying medium and the duration of the treatment may be varied, and they depend on the manner in which the saponification treatment is carried out, that is, by immersion of the materials in the form of hanks, cakes or other packages, or by treatment of the materials while travelling; the saponifying medium may be applied intermittently or to parts only of the materials; the action of the saponifying agent may be assisted by the presence in suspension of lime, baryta, barium or calcium carbonates, &c. as described in Specification 402,106; the saponifying medium may contain a solvent or swelling agent for the materials, or the latter may be treated while in a swollen condition; and the materials may be wetted out before subjection to the saponification treatment.  The materials may be subjected to a stretching operation before, during or after the saponification treatment.  The cellulose esters contained in the materials may be of high or low viscosity.  In examples the following baths are employed--aqueous caustic soda containing turkey red oil; a homogeneous aqueous mixture containing triethanolamine, oleic acid and olive oil; and an emulsion of light mineral oil in soap solution containing caustic soda. Specifications 277,089, 316,521, 318,468, 323,790, 332,263, [all in Class 2 (ii), Cellulose &c.], 340,324, 340,325, 340,326, 340,436, 340,437, 343,062, 370,040, 370,430, 371,461, 371,910, 378,858, 400,938, and 402,104 also are referred to.

[Also in Group XXXVI] Deviations from the linear characteristic of a capacitor transducer 1 (Fig. 8) for measuring thickness, weight, &c., due to the stray capacitance, in parallel with the transducer, are eliminated by controlling the input voltage from generator 13 so that (E 2  - <SP>1</SP>/ n E 1 ) is constant, where E 1  is the voltage across the transducer 1, E 2  is the voltage across a series constant capacitor 2, and n is a constant, determined experimentally, depending on capacitance 2, and the stray capacitance. As shown, an oscillator 13 feeds the series arrangement of transducer capacitor 1 and comparison capacitor 2, the voltages E 1 , E 2  across these capacitors being rectified at 15, 16 and a fraction <SP>1</SP>/ n , determined by the relative values of resistors 20, 21, of the reversed, rectified E 1  is added algebraically to the rectified E 2  and compared at 29, 30 with a constant voltage E 0 , any difference being amplified at 31, 32 to produce a bias voltage E 4  for the oscillator valve 33, whereby the difference voltage (E 2  - <SP>1</SP>/ n E 1 ) is maintained constant. The voltage E 1  across the transducer capacitor 1, or its D.C. equivalent across resistors 20, 21, or the fixed fraction of it across resistor 21, is then linearly proportional to the distance between the electrodes of transducer capacitor 1.

Abstract: 162,549. Scarab Oil Burning Co., Ltd., and Macdonald, F. R. Sept. 16, 1920. Spray burners.-In a self-starting liquid-fuel burner in which the liquid fuel is atomized at starting by compressed air from the upper part of a water reservoir passing through a coil or pipe heated by the burner, and subsequently, when the coil is sufficiently hot, the compressed air is shut off and water from the lower part of the reservoir is passed through the coil and converted into steam to act as the atomizing-fluid, the coil is mounted so as to be adjustable relatively to or removable entirely from the burner when another supply of atomizing fluid becomes available. In the arrangement shown, the water reservoir b is connected by valved air and water pipes c, d and a pipe g to the burner-supporting frame or casting which is divided into two chambers l, m. The coil h is mounted adjustably in passages t<1>, t<2> in the frame and is connected at its ends to the chambers l, m by means of flexible tubes s<1>, s<2>. The pipe g leads into the chamber l and a pipe r connects the chamber m to the burner i. The chambers l, m form lime separators for the air and steam respectively. A large opening in the frame may be substituted for the passage t<1>, t<2> so as to allow the coil to be removed entirely. The burner may be used to heat a small boiler for generating steam. Part of the steam so generated may be used as the atomizing-fluid when available, the coil being then removed to minimize wear. In another arrangement the water reservoir constitutes a small boiler which is heated by the burner to raise steam for starting and operating larger burners. The small boiler may supply steam to its own burner when available.

IPC: F27D11/08
Filed: 1917-09-25
Abstract: 115,017. Webb, J. G. March 16, 1917, [Convention date]. Electrode furnaces. - With the object of diminishing loss of heat and damage to the furnace, a crater is formed within a mass of scrap iron or other metal to be melted by an arc between electrodes arranged at an inclination steeper than the maximum slope of the side of the crater, so as to prevent the arc running up the charge. In the furnace shown in Fig. 2, threephase electrodes 15-17 are situated in one plane, but they may be equidistant. The electric pressure must not exceed a critical value at which, for the particular angle of the electrodes, the arc runs up them. Initially, separate arcs are struck between the electrodes and the flat surface of the charge, then the craters coalesce, and subsequently the electrodes are swung towards each other so that arcs play directly between them as well as on the charge. The final operations are conducted in the usual manner. The electrodes pass through slots 43 in the roof and are suspended by their holders from chains worked by winches. Separate ammeters are connected in series with the electrodes. Surrounding each side electrode above the roof is an insulating sleeve 18, Fig. 4, supported by horizontal pivots in a frame 42, and tilted by a collar 46 and screw 45. The furnace roof may be low, not being exposed to) intense heat; the height of the furnace chamber may be less than its greatest width.

Abstract: 677,673. Automatic voltage control systems. WESTINGHOUSE BRAKE & SIGNAL CO., Ltd., and WALKER, A. H. B. Feb. 5, 1951 [June 2, 1950], No. 13828/50. Class 38 (iv). A cathode coupled pair of valves forms the voltage sensitive element of a voltage regulator. The output voltage of a rectifier 9, Fig. 1, is controlled by a saturable reactor 7 in series with the A.C. supply. The reactor is controlled by a thyratron push-pull amplifier 4, in turn controlled by the cathode coupled pair of valves 19 arranged so that the sum of the currents flowing in the two anode circuits is substantially constant and the transfer from one anode to the other is accomplished smoothly. To the grid of the first valve is applied a portion of the rectifier output voltage, a change, e.g. an increase, in this voltage increasing the anode current of the first valve and correspondingly reducing the anode current of the second. The accompanying increase in the voltage at the second anode correctively controls the amplifier 4. In a second embodiment, Fig. 2, the voltage to be controlled is applied to the first valves of two trigger pairs 19, 30, each arranged so that the transfer of current from the first anode to the second takes place abruptly. In the circuit of each second anode is a relay 22 and 24 respectively, operating contacts, Fig. 3 (not shown), controlling a pair of electric motors operating a regulator. If the measured voltage is low, both relays are energized and the " raise volts " motor is energized. As the voltage rises, valve pair 19 changes over, the contacts of relay 22 change over and the " raise " motor is disconnected. In a further rise, the valve pair 30 changes over, the contacts of relay 24 change over, and the " lower volts " motor is energized. Current compounding may be achieved by injecting a voltage proportional to load current into the grid circuit of the first trigger valve.
