IPC: A61N1/40
Filed: 1938-03-18
Abstract: 513,781. Valve generating circuits. THERMORAY, Ltd., JENKINS, G. M. O., and ADORJAN, P. March 18, 1938, No. 8381. [Class 40 (v)] [Also in Group VI] A thermionic valve oscillation generator has an electric incandescent lamp in the anode circuit of the valve, which, it is stated indicates the output of high frequency current. The valve is preferably a screened grid valve or pentode and two may be in push-pull, also further valves may be arranged in parallel. The arrangement shown in the Figure comprises two screened grid valves V1 and V2 in push-pull connected to the two ends of the inductance L1 the grids being connected to the inductance L2 and the output electrodes to inductance L3 all being coupled together. The inductances have a low impedance ratio and output impedance to minimize variation of output due to movement of the conductors or electrodes, a suitable turns ratio being 4 : 6 : 7, L2 being wound in the reverse sense to the others. Current is supplied to the oscillators from the usual rectifying valve the circuit including an incandescent lamp LR3, a milliameter A and a variable resistance R2 to control the output of the apparatus. An electric incandescent lamp is connected in the cathode lead and is thereby included in the anode circuit and in the grid-cathode circuit, constituting a biassing resistance and by means of its high temperature coefficient of resistance effectively stabilizing the oscillators. The same effect is obtained by the lamp LR2 in the screen circuits of the valves these being decoupled by the condenser C2. The arrangement of inductances RFC and condensers C3 prevents high frequency interference being transmitted to the mains.

Title: New cellulose compounds and process for making same
IPC: C08B15/06
Filed: 1930-03-15
Abstract: Cellulose derivatives are made by treating cellulose with methyl, ethyl or other ethyl isothiocyanates in the presence of alkali. As starting material, there may be used bleached or unbleached cellulose or a material containing cellulose, hydrocellulose, oxycellulose or any alkali-insoluble conversion product of cellulose such, for example, as those obtained by mercerizing cellulose, or by treating the latter with strong mineral acids or zinc halide, or by heating with weak mineral acids, or by grinding in the presence of water. The cellulose may first be treated with aqueous or alcoholic solutions of alkali so as to form alkali cellulose which may be shredded and matured; or the alkali solution and the alkyl isothiocyanate may be applied to the cellulose simultaneously or successively in either order. The isothiocyanate may be diluted with ether, alcohol, etc.; and a small quantity of a copper, nickel or iron salt may be added as a catalyst. The reaction may be carried out without the supply of extraneous heat, or with heating or warming. The reaction product is dissolved in water or alkali, and the solution worked up into technical products; or the cellulose derivative may be isolated by washing the reaction product with water or aqueous alcohol optionally after neutralization or acidification, or alternatively by solution in water or alkali solution, and then by precipitating the cellulose derivative by the addition of an acid or salt to neutralize the alkali; the isolated product may be purified by solution in alkali and re-precipitating. The cellulose derivatives so obtained are generally soluble in aqueous alkali, and insoluble or sparingly soluble in water and organic solvents. The alkali-soluble derivatives are worked up into technical p products, such as:-artificial silk, cotton, wool, hair, straw, etc.; staple fibre; films; plates; plastic compositions; coating and layers; textile-finishing compositions, and compositions for dressing textiles, paper, leather, etc.; sizings for yarns; thickening-agents for pigments as in printing compositions; adhesive, cements, and binding-agents; book cloth; artificial leather; according to the application, the solution is brought to the appropriate shape or form, and is then acted upon by one or more coagulating agents. Suitable coagulating agents are acids, salts, alcohols, acetine, and in fact any coagulating bath known in the viscose art, in particular coagulating and plasticizing baths containing at least 35 per cent, preferably 50-80 per cent, of sulphuric acid or an equivalent amount of another strong mineral acid, as is described in Specifications 274,521, [Class 2 (ii), Cellulose &c.]; or the coagulation and plasticizing may constitute separate steps. Specifications 274,690 and 281,351, [both in Class 2 (ii), Cellulose &c.], also are referred to in the Provisional Specification.

Abstract: 567,115. Superheaters. YARROW, SIR H. E. May 28, 1943, No. 8561. [Class 123 (iii)] A water tube boiler has a steam drum b, a water tube bank c receiving heat by radiation only and a tube bank d through which gases pass from a furnace a. A superheater is divided into two parts, e heated by gases from the furnace a, and e<1> heated by radiation and gases from another furnace f, the gases from which also pass through another generator tube bank g. Full evaporation and steam temperature can be obtained with furnace a only, while, when temperature of furnace a is reduced under reduced load, furnace f is fired to maintain the temperature. The relative areas of parts e, e<1> may be varied by a movable baffle h. An economiser and/or air heater may be arranged in flue k. If lower steam temperature is required, desuperheating by water spray as in Specification 566,514 may be employed. In another arrangement, the tube bank d is divided into two parts, one of which extends across furnace f to screen the superheater tubes el. When applied to a double gas flow Yarrow boiler, a deep bank c is provided, and the gases, which pass on either side of the steam drum, are subjected to damper control which supersedes the spray device. The furnace f then serves as additional temperature control. Specification 394,119 also is referred to.

Title: Photographic recording of sound
IPC: G11B7/00
Filed: 1933-03-25
Abstract: 405,477. Optical sound - recording. RADIO CORPORATION OF AMERICA, 570, Lexington Avenue, New York, U.S.A. March 25, 1933, No. 9099. Convention date, May 9, 1932. [Class 40 (ii).] In photographic sound-recording, distortion arising from decrease in the resolution of the sound record as the frequency of the recorded sound increases is obviated by shifting the median line of the record in accordance with the decrease in resolution. For this purpose, the high prequency components of the electrical impulses produced by the sound are isolated, and employed to modify the mean position of the recording beam. The apparatus shown for carrying out the invention comprises a galvanometer type of recorder 14 which is of usual construction except that associated with the mirror 22 are two actuating coils 16, 17. One of these, 16, is connected directly to the output of the amplifier 13 in circuit with the microphone 10, and the coil 17 is connected to the output of a rectifier 34, 35 which is fed by an auxiliary high-frequency responsive circuit 15, the input of which is connected to the amplifier 13. Since the coil 17 responds only to the higher frequency components of the sound being recorded, it shifts the mean position of the light beam in accordance with the changes in the resolving power of the film at different frequencies. Thus the mean transmission of the film is made constant for all useful frequencies.
