Patent GB-714780-A (GB)
Title: Process and apparatus for the refining of hydrocarbon oils with production of fuel gas
IPC: C10J3/46
Filed: 1951-12-21
Abstract: <PICT:0714780/III/1> Hydrocarbon oil, e.g. crude petroleum residues, is supplied to a hot fluidizing bed of inert material into which also a mixture of steam and air is introduced so as to effect a coking reaction at p  a temperature of about 1000 DEG -1800 DEG  F. with formation of carbon, oil vapours and a producer gas mixture.  The mixed gas and vapour reaction products pass to a separating zone in which a gas mixture of carbon monoxide carbon dioxide, hydrogen and nitrogen is led off from oil products such as gas oil and gasoline. Crude oil heated in the lower portion of a fractionator 10 by direct contact with the reaction products is distributed over a bed 18 of powdered or granular material, e.g. silica or alumina, which is fluidized by steam and air admitted through a conduit 20.  The heat of reaction is controlled by means of a steam generating coil 23 within the bed.  The reaction products after heating the crude fuel ascend through contact devices 11 to form varying fractions, e.g. gas oil withdrawn through a line 33 and gasoline through a line 34. Gaseous effluent passes through a condenser 36 and receiver 37, condensed gasoline being pumped into line 34.

Title: Improvements in automatically controlled illuminated advertising signs
IPC: G09F11/295
Filed: 1925-11-27
Abstract: 252,998. Goldberg, J. A. Nov. 27, 1925. Reel and non-endless web apparatus; moving- apparatus combined with clocks; actuating and controlling; illumination, changing advertisements by controlling.-An advertisement band B is moved intermittently under the control of clockwork U, and is illuminated during the intervals of rest by an automatically lit lamp L. When the clockwork makes contact the motor M is energized through lead 1, switch 2, 3 and lead 4, and one of the drums T, T<1> is positively rotated. The band B moves till a contact thereon closes a switch 13, when an electromagnet S is energized and attracts an armature S<1>, breaking the contacts 2, 3 and making contacts 5, 6. The motor M now stops and the lamp L is lit. The band B moves by inertia sufficiently far to open the switch 13, so that the energizing of the magnet S is only temporary. A time switch Z breaks the contacts 5, 6 after an interval, and makes contacts 2, 3, ready for another completion of the circuit by the clockwork U. The band B is built up of side ribbons of steel or brass connected at intervals by rods 12 to which pictures are attached by loops. Spacing sleeves at each end of the rods 12 act as contacts for making the switch 13. The band is reversed by a prejection thereon which throws over the motor driving belt from one fast pulley to another. The band is seen through a transparent mirror, and the device may be combined with a clock, barometer, show case, cupboard, &c.

Title: Coupling circuit for high frequency transmission systems
IPC: H01P5/08
Filed: 1953-10-30
Abstract: 744,715. Impedance matching. STANDARD TELEPHONES & CABLES, Ltd. Oct. 30, 1953 [Nov. 29, 1952], No. 30093/53. Class 40 (8). Two sections of a transmission system having different impedances are coupled by a waveguide having matching means at either end and being dimensioned below cut-off, the different impedances at either end producing a reflection to permit transfer of real energy therethrough. In the embodiment shown a magnetron 2 is coupled by means of a longitudinal output slot 7 to a cylindrical or other waveguide 4 which operates at cut-off for the power coupled out of the magnetron. The waveguide provides a load impedance which varies approximately as the frequency squared, such as is required by the magnetron. To provide the correct guide impedance an iris 9 is provided near one end of the guide. The termination 10 is chosen to produce a reflected wave which, in combination with the direct wave, will result in a total field Poynting vector whereby power is transmitted through the cut-off guide. Impedance transformer ramps 8 may be employed to control the impedance of the waveguide with respect to the impedance of the magnetron oscillator as described in Specification 687,573.

Filed: 1953-10-31
Abstract: The invention comprises the 4-methoxy-, the 4,7-dimethoxy, and the 4-ethoxy derivatives of 6 - hydroxy - benzofuran - 5 - carboxylic acid.  Benzofuran derivatives having the formula <FORM:0761376/IV(b)/1> in which R1 is an alkoxy group, and R11 is hydrogen or an alkoxy group, R1 and R11 being similar or different, are produced by oxidizing at a temperature not exceeding 60 DEG  C., a furochromone having the formula <FORM:0761376/IV(b)/2> in which R is hydrogen or an alkyl group and R1 and R11 have the above-defined meanings, by means of hydrogen peroxide, in an amount not exceeding a quantity corresponding to 10 cc. of a 30 per cent by volume aqueous solution of hydrogen peroxide for every 2 gm. of the furochromone, in an alkaline medium.  In the preferred starting materials, the alkoxy radicals R1 and R11 contain not more than 6, more preferably not more than 4, carbon atoms, e.g. methoxy and ethoxy; R is preferably an alkyl radical containing not more than 6, more preferably not more than 4, carbon atoms, e.g. methyl or ethyl. The oxidation is preferably effected at 20 DEG  to 60 DEG  C. at atmospheric pressure using 4 to 10 cc. of 30 per cent by volume hydrogen peroxide for every 2 grams of furochromone.  The hydrogen peroxide may be formed in situ using a metal peroxide, e.g. an alkali metal peroxide.  The amount of alkali present should amount to, for example, 2 per cent to 15 per cent of alkali metal hydroxide by weight of the furochromone. The reaction may be stopped by acidification shortly after the furochromone has dissolved or the reaction solution may be left to stand for up to 24 hours before isolating the product.  In examples (1) visnagin, (2) khellin and (3) 2-norvisnagin are oxidized with an aqueous solution of hydrogen peroxide in the presence of sodium hydroxide to give (1) 4-methoxy-, (2) 4,7-dimethoxy and (3) 4 - methoxy - derivatives of 6 - hydroxybenzofuran - 5 - carboxylic acid, respectively; (4) 5 - hydroxy - 2 - methylfuro - 41,51,6,7-chromone is ethylated with ethyl iodide in acetone to give the 5-ethoxy derivative which is then oxidized by the procedure of (1) to give 4 - ethoxy - 6 - hydroxybenzofuran - 5 - carboxylic acid.  The product of Example (1) is benzofuran - 5 - carboxylic acid.  The product of Example (1) is methylated by refluxing with methyl iodide and potassium carbonate to give 4,6-dimethoxy-5-carbomethoxybenzofuran.
