Abstract: 718,585. Automatic pressure and flow control systems. LANDIS & GYR AKT.- GES. Dec. 5, 1952 [Dec. 7, 1951], No. 30989/52. Class 38(4) A web (not shown) of paper or textile passes over a drying cylinder 1, the supply of steam to which, through conduit 2, is measured in order to estimate the moisture content of the web, and the supply of steam through conduit 4 to following drying cylinders 3 is controlled in accordance with the moisture content so that the required degree of dryness is produced in the web. A gauge 5 responsive to steam pressure in conduit 2 operates an inductive electrical device 6 associated with a manually adjustable inductive electrical device 8 to control, through a two-way relay 9, a reversible servomotor-operated valve 11 to maintain steam pressure in conduit 2 at a value determined by the setting of device 8. Suitable servo-systems employing inductive devices are described in Specifications 609,484, 633,689 and 633,753. To prevent hunting transient thermal feedback is applied to device 8 by relay 9 in a manner similar to that described in Specification 640,503. A flow meter 14, associated with an orifice plate 13, which indicates and records the steam flow and hence moisture content, also operates an inductive electrical device 15 associated with a manually adjustable inductive electrical device 21 to control, through a two-way relay 22, an electrically operated valve 24 controlling the supply of steam to conduit 4 and hence cylinders 3. To prevent hunting, transient feedback is provided by gauges 16, 17 associated with differently adjusted throttles 25, 26 so as to respond at different speeds to pressure variation in conduit 4. These gauges operate inductive electrical devices 18, 19 which are oppositely connected in the servo-system.

Abstract: 1,070,529. Velocity-modulated tubes. SPERRY RAND CORPORATION. Aug. 4, 1964 [Aug. 12, 1963], No. 31055/64. Heading H1D. An electron gun for producing a hollow focused electron beam includes means for producing a magnetic field which, in the region of the cathode diverges from the axis, the cathode having a curvilinear emissive surface disposed either to coincide with a radially diverging field line, or tilted back, axially, with respect to the field line which cuts its radially innermost edge, whereby electrons emitted from any point of the surface possess a magnetic potential not greater than that of electrons emitted from points less remote from the axis. A focusing coil 11, Fig. 2, provides an axial field within the drift tube 25 of a klystron or travelling wave tube, and, with a bucking coil 12, a radially diverging end field in which the gun cathode 17 is mounted with its emissive surface 18 coincident with the flux lines. The gun further includes focusing electrodes 23 and 24, and an anode 20 which provides a substantial axial component of electric field. In another embodiment (Fig. 7, not shown) the emissive surface is tilted back with respect to those flux lines which pass through its front edge. In a further embodiment (Fig. 10, not shown) which includes focusing electrodes (87) and (88) and an anode (85), the cathode surface is located in a region in which the flux lines have reversed slope. The diverging magnetic field may, alternatively, be produced by permanent magnets opposed endto-end. The equations of electron flow in the beam are derived; comparison with the solid beam case is made; and the effect on the beam of various flux density distributions in the diverging field regions are discussed.

Title: Improvements in or relating to the conversion of carbonaceous materials into low boiling hydrocarbons by treatment at elevated temperatures with hydrogenating gases
IPC: C10G1/08
Filed: 1936-11-18
Abstract: Coals, asphalts, high-boiling crude oils, tar fractions and high-boiling hydrocarbons are converted into lower-boiling liquid hydrocarbons by subjecting them to hydrogenation in the presence of melted naphthalene and/or alkyl or aryl naphthalenes which form hydrogenated naphthalene compounds under the reaction conditions, with or without addition of catalysts not liable to poisoning. Saturated or unsaturated dilution agents including fractions of the reaction product may be added, also powdered coke or anthracite to increase the surface of contact.  The reaction may be carried out from 200 DEG  C. upwards; at 400-500 DEG  C. aliphatic hydrocarbons are formed, and at 600-800 DEG  C. aromatics and semiaromatics.  The latter can be cracked to aromatics.  In an example, 2000 gm. Pittsburgh coal mixed with an equal weight of naphthalene and 20 gm. molybdenum sulphide or tin sulphide are treated at 100 atm. and 425 DEG  C., being converted to the extent of 80 per cent into liquid hydrocarbons of b.p. 50-300 DEG  C.  Reference has been directed by the Comptroller to Specifications 283,545, 301,946, 309,229, and 320,918, [all in Class 32], and Canadian Journal of Research, Volume 12 (1935), pages 832-9.

Title: Improvements in and relating to the manufacture of sulphurised dyes from carbazole-derived indophenols
IPC: C09B49/10
Filed: 1922-11-18
Abstract: The sulphurizing of carbazole-indophenols by heating with a thionating agent in an alcoholic medium is conducted under conditions precluding ebullition, for example, by heating under pressure; the thionating agents mentioned are sodium and potassium polysulphide in methyl, ethyl, propyl, or butyl alcohol.  The products differ from the corresponding products of Specification 18822/09 and dye cotton in fast violet shades from the hydrosulphite vat.  In an example a carbazole-indophenol prepared according to Specification 201,624 is heated with ethyl- or propyl-alcoholic sodium polysulphide in an autoclave at 95-100 DEG  C; the dyestuff is isolated by diluting with water, distilling off the alcohol, and precipitating with acid; it is freed from sulphur by a solvent such as benzene or toluene.  The alcohol must not be distilled off before diluting with water and it is preferred to exclude traces of metals such as iron, phosphor bronze, and copper from the reaction.
