Title: High speed facsimile method and apparatus
IPC: H04N1/028
Filed: 1966-02-21
Abstract: 1,099,040. Pictorial communication. BECKMAN & WHITLEY Inc. Feb. 21. 1966 [March 29, 1965], No. 7499/66. Heading H4F. The invention relates to very high-speed facsimile production suitable for use in reproducing on Earth a photograph taken by a rocket &c. The recording and reproducing systems use exactly the same scanning system, Fig. 1, showing its use in the reproducing system. A light beam from a gas laser 10 is modulated by a Kerr cell 11 in accordance with modulating signals received from the recording system. The intensity modulated beam is broadened by lenses 12 and 13 and is split into two equal halves 16, 17 by beam splitter 14. The two beams are focused by lenses 20 and 21 respectively and directed by mirrors 30 and 34 on to mirrors 27 and 28 respectively. Mirrors 27 and 28 are in the form of equilateral prisms, with one prism turned by 60 degrees with respect to the other, and both rotating at 2500 r.p.s. about a common axis. The two beams reflected by the mirrors 27 and 18 fall and are focused on a photo-sensitive film 23 moving in a direction 25 and formed into an arc extending over an angle of 120 degrees with respect to the rotation axis of the mirrors. The system is such that when the beam from mirror 27 has just finished its downward scan of the film, that from mirror 28 is just beginning its downward scan at the top of the film. The film is thus scanned alternatively by the two beams, such that together with the motion of the film, a facsimile is produced on the film. At the recording system, Fig. 2 (not shown), the two unmodulated light beams alternately scan the picture (35) to be reproduced and the modulated light passing through the picture is collected by a bundle (37) of glass fibres and fed to a photo-sensitive cell (39) to produce the modulation signal for transmission to the reproducing system.

Abstract: 730,290. Flat-flame burners. NATIONAL RESEARCH DEVELOPMENT CORPORATION. March 20, 1953 [March 24, 1952], No. 7533/52. Class 75 (1). The invention consists in a process for the combustion of a fluid mixture as a thin disc-like flame and a burner for carrying out the process, the process comprising passing a combustible mixture through a foraminous plate 1 prior to ignition, controlling the temperature of the downstream surface of the plate at a value below the thermal reaction temperature of the mixture and maintaining the flow velocity of the mixture at a value not exceeding the laminar adiabatic flame speed of the mixture so that the flame 8 is maintained at a short distance beyond the downstream surface of the plate, the burner comprising a foraminous plate 1 preferably made of high heat conductivity material such as sintered bronze and a heat exchanger associated with the plate and having a capacity sufficient for maintaining the temperature of the downstream surface of the plate at a value below the thermal reaction temperature of the mixture. The heat exchanger may comprise a jacket 4 surrounding or embedded in the plate or contacting the upstream surface of the plate and through which air or water circulates. The foraminous plate may comprise one or three superposed plates or it may consist-of intersecting thin plates set edgewise to the flow of the combustible mixture or of a series of gilled tubes. In the apparatus shown in Fig. 6 the combustible mixture passes through a foraminous plate 1 and burns in a combustion chamber 7 in which a sub-atmospheric pressure is maintained by the action of an ejector nozzle 18 located in a venturi outlet 19 the nozzle 18 being fed with the air or water which cools the foraminous plate.

Filed: 1925-03-20
Abstract: 232,193. Siemens - Schuckertwerke Ges. April 10, 1924, '[Convention date]. Systems depending on the use of two or more machines.-The power factor of the main n is influenced by an asynchronous wattless current machine a, connected in parallel therewith, and a separately excited rotary current exciting machine k. The machine k is excited through a tapped transformer r or rotary transformer, or by a separate auxiliary machine at main frequency. A stator fed commutator machine may be used instead of the rotor fed machine k. In order that the machine a may give a wattless efficiency to the net, or main, the exciting of the machine k may be adjusted by means of the transformer r so that the machine a is excited not from the mains n but from the machine k. At starting, the commutator machine is run as an asynchronous machine, and for this purpose it may be provided with a squirrel cage winding. If the machine k has compensating winding c, this is provided with an adjustable shunt resistance r, and the machine is started with the winding c as a secondary winding and the resistance r as a starting resistance, the machine a being disconnected from the mains.

Title: Improvements in or relating to cooling of molten metals

Abstract: 981,546. Cooling liquids in bulk; plate heat exchangers. BROKEN HILL ASSOCIATED SMELTERS PROPRIETARY Ltd. Feb. 26, 1963 [Feb. 27, 1962; Dec. 20, 1962], No. 7732/63. Heading F4S. Molten metals, e.g. lead, are cooled while flowing through an open channel 10 by a plurality of immersion coolers 28 arranged at intervals along the length of the channel. In order to remove shells of solidified metal which accumulate on the coolers 28 the latter are periodically withdrawn from the channel by hydraulic assemblies 36, 39, 40 and the flow of coolant is continued so that the shells crack and drop back into the channel where they are remelted. The coolers may be withdrawn sequentially or simultaneously, preferably under automatic control. As shown in Figs. 4 and 5 each cooler 28 comprises a hollow plate element having connections 30, 31 to a cooling water supply and internal partitions 32 which cause the water to flow in a tortuous path within the element. Projections 29 are formed at the sides of the plate, which projections cool down less quickly than the remainder of the plate when the latter is withdrawn from the channel and thus produce zones of weakness in and splitting of the shells. The molten lead is supplied to the channel 10 from a chamber 12 (Fig. 2) by a pump 16 which discharges via a pipe 24 into a chamber 20 having a depending outlet 26, and the channel discharges into a further chamber having agitating means for breaking up any solidified metal (Fig. 3, not shown). In modifications, the coolers may be moved out of alignment with the channel after withdrawal therefrom so that the shells are not returned to the channel or alternatively a shoot may be arranged below the withdrawn coolers for this purpose. Specification 978,204 is referred to.

Title: Improvements relating to reducing the aromatic content of petroleum distillates
Inventor: CHAMPAGNAT ALFRED
IPC: C10G65/08
Filed: 1958-03-13
Abstract: The aromatic content of petroleum distillates boiling within the range 60-250 DEG C. is reduced by firstly catalytically hydrofining to reduce the sulphur content to at most 0.002%, removing dissolved hydrogen sulphide and catalytically hydrogenating the product in the presence of at least 50 litres per kg. of feedstock of excess hydrogen and a supported reduced nickel catalyst preferably at 100-200 DEG C., 70-430 p.s.i.g. and a space velocity of 0.5-5 v/v/hr. to reduce the aromatic content to 1% or below.  The hydrogen used in either stage may be pure hydrogen or a hydrogen-containing gas, e.g. from a reforming process; excess hydrogen from the desulphurization step after removal of hydrogen sulphide may be used in the hydrogenation. The preferred desulphurisation catalyst is one of cobalt and molybdenum oxides, as such or combined, supported on alumina. Hydrogen sulphide may be removed by washing with caustic soda or by stripping with steam or an inert gas followed, if necessary, by a light soda wash.  In the second step the nickel catalyst may be supported on silica which may contain a minor proportion of cobalt.
