Title: Improvements in speed-governing devices for hydraulic impulse turbines
IPC: G05D13/00
Filed: 1920-05-21
Abstract: 143,572. Maschinenfabrik Grevenbroich. Jan. 23, 1919, [Convention date]. Regulating.-In hydraulic impulse turbines, the nozzle area is permanently reduced after the turbine has reached its normal speed in starting. Fig. 1 shows the position of the control devices when the turbine is at rest. The stop valve u being opened, the turbine accelerates, and, at a certain speed, the governor s raises a piston valve g. The upper part of the piston closes an outlet pipe i, and the lower conical part f admits pressure fluid behind a piston d, which is thereupon moved forward, and a pin valve b reduces the nozzle area at a. The upward pressure of the fluid on the piston g thereafter prevents any further control by the governor.

Title: Limiting of movement of a winning tool

Abstract: 1477974 Automatic control of attitude EICKHOFF MASCHINENFABRIK U EISENGIESSEREI mbH Gebr 7 April 1975 [8 April 1974] 14129/75 Headings G3N and G3R [Also in Divisions El and H3-5] A winning tool 5 mounted on a universally pivoted support arm 4 of a tunnelling machine 1 has its position determined by a laser beam extending in the direction of the tunnel and its range of movement limited by a template 22 similar to the required tunnel cross-section, the template being sensed by a reflection light barrier 25 which provides set values for the tool co-ordinates and these set values are corrected, in the event of deviation of the machine from its set value position, by signals corresponding to the deviations of the machine from a receiver 31 receiving the laser beam. The receiver is vertically and horizontally adjustable on the machine frame and has two surfaces 32, 41 carrying photo-sensitive elements. The surface 32 is divided into portions a to d and carries the photo-sensitive elements 34 in an array surrounding a passage 38 whose diameter corresponds to that of the laser beam. Each surface portion a-d is connected, by way of amplifiers 45 to 48, common servomotors 49, 50 and their respective angle codes 53, 54, to difference amplifiers which receive the reflection light barrier set values so that these portions will react in the event of deviations of the machine, to the control signal output by the iradiated photo-sensitive element to move the two receiver surfaces until the laser beam passes through the passage 38 to the rear receiver surface 41. The photo-sensitive elements 43 of the surface 41 are each connected so that, when iradiated, it will supply to the difference amplifiers 16, 17 an electrical signal corresponding to the angular deviations. An electric inclinometer 58 is provided to continually correct the range of operation of the tool 5 so that the tunnel floor extends horizontally. In a further embodiment rotational deviation is detected by placing a lens, having a diaphragm formed with a cruciform aperture, immediately after the passage 38 so that a cross of light impinges on the surface 41.

Abstract: 568,593. Distilling used oils. FOSTER WHEELER, Ltd., and FISCHER, R. K. Sept. 12, 1940, No. 14143. [Class 32] In recovering benzene &c. from gases, e.g. town gas, by absorption of the benzene in a lean absorber oil followed by distillation of the enriched oil, the latter is heated by heat exchange with the lean stripped oil and then flashed under a pressure higher than that prevailing in the absorption vessel to remove light fractions before passing to the still in which the benzene is recovered. Town gas is fed upwardly through an absorber 1 in countercurrent to lean oil and the enriched oil is fed by a pump 3 through a heat exchanger 4 where it receives heat from the stripped lean oil passing from the still 2 to the absorber 1. The oil after further heating in a heat exchanger 5, if necessary, is flashed under a pressure of about 5 lbs. per sq. in. in a chamber 6 to separate hydrogen, methane, &c. which are recycled with the gas charge while the degassed oil is fed to the still 2 maintained under vacuum by a steam jet 8 acting through a condenser 9 arranged in an extension of the still. Condensate is returned in part as reflux, the remainder passing to a separator tank 10.

Title: Process for preparing olefins by cracking high boiling hydrocarbons
IPC: C10G9/38
Filed: 1954-05-18
Abstract: Olefins are obtained by rapidly heating a hydrocarbon mixture boiling above about 300 DEG  C. containing less than 25 per cent by weight of aromatics in a relatively small heating zone containing a solid oxidationpromoting substance to at least 500 DEG  C. by effecting complete combustion of part of the mixture with the aid of an oxygen-containing or oxygen-producing gas in the zone and then passing the hot effluent through a zone in which cracking of the mixture takes place.  Combustion may be effected by adding oxygen, air, nitrogen oxides or ozone and passing the mixture through activated alumina, bauxite, silica gel, titanium oxide, cerium oxide, thorium oxide, chromium trioxide, vanadium pentoxide, or oxides of cobalt or manganese.  Normally from 10 to 15 per cent by weight of the supplied material is burnt.  The non-aromatic part of the initial feed may be normal paraffins, isoparaffins and naphthenes if olefins of less than 6 carbon atoms in the molecule are required.  If however higher olefins with a straight carbon chain is desired then the starting material should contain more than 60 per cent by weight of paraffins. Cracking temperatures of 650-900 DEG  C. may be used and residence in the cracking space may be from 0.001 to 3 seconds. Steam may be used as a diluent.

Title: Improvements in hydrocarbon fuel compositions
IPC: C10L1/14
Filed: 1941-11-14
Abstract: Stabilised hydrocarbon fuel compositions comprise a hydrocarbon fuel containing a small quantity of a condensation product having the general formula: [R.Ar(OH)CH2]nX, where R represents at least one alkyl group substituent in the aromatic nucleus Ar, the subscript n is an integer, and X represents an amino group or an equivalent base radical.  The additives are obtained by condensing an alkyl phenol with formaldehyde in the presence of a hydrogen halide acid and reacting the product with ammonia or equivalent organic base.  The intermediate product is an alkyl hydroxy benzyl halide and the final product the corresponding amine or equivalent.  Typical compounds comprise primary, secondary and tertiary alkyl hydroxy benzylamines, and compounds in which the hydrogen of the base radical is substituted, viz.: [R.Ar(OH)CH2] N(R1)2, where R1 may be alkyl, cycloalkyl, or aryl.  The bases equivalent to ammonia may comprise an amino compound, an organic nitrogen base, or other organic bases containing other metalloids, such as phosphorus.  The alkyl substituent of the aromatic nucleus preferably contains at least 3 carbon atoms, such as isooctyl. The products are usually resinous and in the case of ammonia consist of mixtures of the p, s and t amines. Polymers of the general formula [R.Ar(OH)CH2]n[N(R1)2]m, obtained by heating a monomeric compound, may also be used.  The additives particularly stabilise compositions containing a metallo-organic anti-knock agent.  Full details are given of the preparation of the ammonia derivatives in which the phenol is p-isooctyl phenol.  The latter dissolved in benzol is slowly added to a solution of paraformaldehyde in strong HCl, the solution being saturated with HCl gas, and after stirring the benzol solution is separated from the acid liquid.  A mixture of this solution and dilute liquid ammonia solution in isopropyl alcohol is then heated in a bomb at 110 DEG  C. and the reaction mixture finally transferred to an open vessel and diluted with naphtha and water.  The resinous products are recovered from the separated naphtha solution.  The additives may be blended in proportions of 0.01 to 0.5 per cent by weight with gasoline, naphthas, kerosene, Diesel fuels, and fuel distillates generally of boiling range 100-700 DEG  F.  The compositions may also contain other usual blending agents.
