Title: Improvements relating to the catalytic reforming of non-aromatic hydrocarbons
IPC: C01B3/38
Filed: 1957-08-08
Abstract: In the catalytic dehydrogenation and/or dehydrocyclisation of a non-aromatic hydrocarbon at a temperature of 450-600 DEG C. using chromium oxide on alumina as catalyst to produce an aromatic hydrocarbon and hydrogen, methane contained in the hydrogen product is converted to further hydrogen by reaction at elevated temperature with steam.  The hydrocarbon treated may boil in the gasolene or naphtha range.  The major proportion of the hydrocarbon preferably boils below 100 DEG C.  The catalyst may contain 5-25% chromium oxide, 0.1-5% of alkali metal oxide, e.g. potassium oxide and o.1-5% rare earth oxide, e.g. cerium oxide. The catalyst may also include boron, bismuth, germanium, nickel, or manganese oxide; cobalt, copper, or iron chromite; or zinc titanate.  The catalyst may be in a fixed, moving, or fluidised bed.  The dehydrogenation step may be carried out with or without recycle of hydrogen, at a pressure of up to 50 p.s.i.g., at a space velocity of 0.1-1.0 v/v/hr., and at a temperature of 525-570 DEG C.  The conversion with steam may be effected at a temperature of up to 1000 DEG C., preferably 430-650 DEG C.  According to the example gas containing 67% of hydrogen and 15% of methane is produced by the dehydrogenation of light gasolene, using 10% chromia on alumina promoted with 1% cerium oxide and 1% potassium oxide as catalyst, a temperature of 560 DEG C., atmospheric pressure, a space velocity of 0.2 v/v/hr., and a reaction time of 5 hrs; and the hydrogen content of the gas is increased to 87% by reaction with steam in a volume equal to six times the volume of methane in the gas, at a temperature of 600 DEG C. and in the presence of nickel and manganese on alumina as catalyst, in three stages with removal of carbon dioxide between each stage.

Title: Controlling the prime mover in electrical generating installations
IPC: B23K9/10
Filed: 1950-10-18
Abstract: 683,573. Generator control systems. PETERS, J. A., BIRD, R. C., and PUTTICK, H. G. Oct. 18, 1950, No. 25415/50. Class 38 (iv). A control system for a prime-mover driving a welding or other intermittently loaded generator, which automatically moves the throttle, or other fuel valve, to idling position when the generator becomes unloaded for a predetermined (but adjustable) time, comprises relays A-C and throttle-actuating solenoid S all connected across generator. Upon interruption of the load circuit, the high open circuit voltage of the generator (about 60 volts) causes relay B to respond, opening its contacts b1 to disconnect relay A from the machine. After a time, determined by the time-constant circuit R, D, relay A drops out and closes its contacts a1 a2 to effect energization first of relay C and then of solenoid S. The last throttles down the engine and provides a further interruption at contact s1, in the energizing circuit of relay A. The generator volts fall to about two, but C and S hold in; B releases, however, and closes contact b1. Contact m is manually operated and normally closed. If the load circuit is again closed, C and S release on account of low voltage; the engine consequently runs up to full speed and when the generator volts reach about 25 relay A responds to prevent actuation of C and S. The system may be duplicated, apart from the solenoid S, in the case of a single engine driving two generators feeding separate load circuits.

Abstract: 389,140. Coated fabrics. DU PONT DE NEMOURS & CO., E., I., Wilmington, Delaware, U.S.A. Sept. 11, . 1931, No. 25518. Convention date, Sept. 27, 1930. [Class 140.] Coated fabrics such as artificial leather, leather cloth, &c., are made by applying to a textile fabric a composition comprising cellulose nitrate, a wax or wax-like material, and a softener in an organic solvent, the proportions of the ingredients being such as to produce in the resulting film, owing to the incompatibility between the wax and the cellulose nitrate, a discontinuity which may vary from a slight cloudiness to an almost complete breaking-up of the film. The specified proportions of cellulose nitrate, wax or wax-like substance and softener lie between the limits 5 : 1 : 5 and 15 : 9À5 : 15. The coating is preferably applied over one or more undercoats comprising cellulose nitrate and a softener. The fabric may be affixed to a second fabric. In the method described, a woven fabric 1 is dyed to a colour approximating to that of the finished product, and coated with two coats of a composition comprising cellulose nitrate, a softener such as castor oil, and a pigment. Two further coats 2 of the same material are then applied by means of a doctor knife having a dull edge. The material is then embossed with a grain. For two-tone effects, a further coat of composition of another colour may be applied. The coated material is then combined by means of an adhesive 3 with a second fabric 4. The coating 5, consisting of specified percentages of cellulose nitrate, ceresin wax, dibutyl phthalate, ethyl acetate, ethyl alcohol and toluol is then applied. In making the composition, the wax is melted and mixed with warm toluol. To the solution is added cellulose nitrate in ethyl acetate and alcohol. The mixture is stirred till smooth and the dibutyl phthalate added with continued stirring. A lustrous finish may be obtained by further embossing. Alternative waxes &c. are carnauba wax, candelilla wax, paraffin wax, solid hydrocarbon waxes of cyclic type, japan wax, montan wax, spermaceti wax, and hydrogenated castor oil. Other suitable softening agents are dibutyl tartrate, tricresyl phosphate, raw or blown castor oil, and blown cottonseed oil. The coating 5 may be applied directly to the fabric.

Title: Glass-forming method and apparatus
IPC: C03B11/02
Filed: 1964-06-19
Abstract: In the pressing of glassware, e.g. table ware, the pressing plunger is retracted while the glass (or glass ceramic) is still semi-plastic and the shape of the ware is maintained during cooling by pressing it against the mould by an air stream which is directed against selected areas of the ware and simultaneously cools its upper surface. Moulds 16-18 on a rotatable table 11 are moved successively beneath a plunger 22 for forming the article and then under a rotating element 93 from which jets of air are projected to press the framed article against the mould. The element 93 is constructed of four L-shaped members 102-105 bolted together to form a hollow space opening towards the face of the mould through narrow slots 99 and to a hollow shaft 49 connected to a source of air under pressure.  The shaft 49 is rotated at high speed from a motor 27 and is raised and lowered by fluid pressure in a cylinder 66.  The air escapes from the article through the relatively large spaces between the arms of the members 102-105. The variables are selected so that the upper surface of the pressed article cools at approximately the same rate as the surface in contact with the mould.
