Title: Improvements in and relating to methods of and apparatus for regulating explosion turbines
IPC: F02C9/28
Filed: 1932-01-01
Abstract: 377,092. Turbines. HOLZWARTH, H., 7, Goethestrasse, Dusseldorf, Germany. Jan. 1, 1932, No. 106. Convention date, Jan. 2, 1931. [Class 110 (iii).] In an explosion turbine plant the volume of charging air delivered by the compressor per unit of time, measured in the condition of delivery to the combustion chambers, is kept constant over the range of regulation, the pressure of the charging air being altered while the number of explosion chambers and the number of working cycles is kept constant. The speed of a steam turbine 6 which drives a compressor 5 is altered in accordance with the fluctuations in the speed of the explosion turbine 1. When the output of a generator 4, driven by the turbine 1 and the continuous flow turbine 2, falls below normal, the excess of air delivered by the compressor 5 to the turbine 1 is led to the turbine 2. Steam raised from waste heat of the exhaust gases is used to drive the turbine 6. Steam enters a pipe 10 and passes by way of a valve 11 and pipe 12 to the turbine 6. Valve 11 is controlled in accordance with the fluctuations in speed of the explosion turbine 1 by means of a regulating rod 13 of the speed governor 14. The rod 13 is connected to a slide valve 15, of a servomotor 16, which admits or releases fluid to or from the upper side of a piston 17 supported by a spring. A valve 20 of a fuel pump 8 is under the influence of the charging air by way of a pipe 21 and a piston 22 so that independently of the alterations in the condition of the charging air, the specific heat content of the charges to be supplied to the explosion chamber of turbine 1 can be adjusted to be constant. A second steam inlet pipe 37 admits steam to the turbine 6 when the valve 11 is partially closed by way of a valve 38 under control of a piston 32 which is balanced between steam pressure in the pipe 37 and that of a spring 33. Excess air from the compressor 5 is led from the pipe 7 to the continuous flow turbine 2 by way of a valve 23 controlled by a piston 25 through an angle lever 24. A sleeve 36, clamped to the rod 13, controls the admission to or release from the slide valve 26 of fluid which acts on the piston 25 to open the valve 23. A pipe 30 admits air under pressure from the pipe 7 to act under a piston 29 to restore the position of the slide valve 26.

Abstract: 228,132. Naamlooze Vennootschap Philips' Gloeilampenfabrieken. Jan. 26, 1924, [Convention date]. Void [Published under Sect. 91 of the Act]. Coiling; dies.-In coiling wire helically on a travelling mandrel wire, particularly for making close helices of tungsten for use in electric incandescent lamps, the mandrel wire is fed through an aperture in a guideway along the surface of which, on the side on which the mandrel wire enters the aperture, the wire to be coiled is conducted so as to be supported thereby. The wire 12 to be coiled is carried by a spool 10 mounted on a head 9, which is rotated on ball bearings 5, 6 in a bushing 3 secured in a housing 2. The guideway 15, which may be a diamond or other hard material when coiling tungsten wire, has a convex end projecting slightly from a guide box 14, which is secured to a column 22 fixed by a screw 23 in a longitudinally adjustable slide 19. The guide box may be adjusted vertically by raising the column and laterally by turning the column. The mandrel wire 13 is fed at a uniform speed through the hollow spindle 7 of the head 9 and through apertures in the guideway 15 and guide box 14 and passes over a roller 26 mounted on a forked arm secured by a screw 25 to the column 22. The wire 12 is led over a roller 11 carried by the head and engages with the convex surface of the guideway at an angle to the mandrel wire slightly less than a right angle. The guideway is heated so that the wire 12 is heated at the point where it is bent for the coiling operation and the mandrel wire also heated. The guide box for this purpose may be electrically heated by a coil 17 contained in a mantle 16 or the guide box may be in two parts to receive the coil. The guideway may be stationary or be carried by the coiling-head so as to rotate therewith round the mandrel wire as an axis.

Abstract: 936,941. Sewing machines. JET SEW Inc. Jan. 8, 1962, No. 644/62. Class 112. In stitching a sliding clasp fastener tape 38 to tapes 74 and 76 in a sewing machine, a pull-feed is provided on the delivery side of the machine, and the tape 38 is fed to the machine by a roller running at a slightly lower rate than the pull-feed, in order to tension the work. A twin-needle machine 14 is mounted on a table 12. The fastener tape 38 is led from a drum 26 through a D-shaped guide 70 and through an H-shaped guide 56 which is angularly and laterally adjustable. The tape 38 then passes over an idler roller 52 carried by an arm 54 rigid with guide 56, and over a driving roller 50. The latter is carried by a shaft 48 driven by a belt 49 from a variable speed gearbox 44 which is driven by a belt 46 from a motor 20. The tape 38 then passes through a fixed channel guide 72 to the twin needles 30 of the sewing machine where it is joined by the strips 74 and 76, the work passing between a support plate 32 and a foot 28. Plate 32 is formed with a groove 34 to accommodate the fastener elements. Foot 28 is not pressurebiased, but merely rests on the work. The needles are arranged to swing in the line of stitching to assist the feed. The completed work passes between a pair of rollers 36, 36<SP>1</SP>, the lower roller 36 being positively driven, and the upper roller being downwardly biased by a spring 42. The amount of tension is controlled by varying the speed of roller 50, varying the amount of bight around roller 50 by varying the position of roller 52, and by varying the amount of braking applied to shaft 48 by brake blocks 64 and 66 adjustable by means of screws 68.

Patent GB-938836-A (GB)
Title: Process for the manufacture of carbonyl compounds
IPC: C07C45/34
Filed: 1960-01-07
Abstract: Carbonyl compounds are obtained by the process in which an olefine is reacted with molecular oxygen in the presence of a liquid aqueous acid or neutral catalyst comprising at least one salt of a metal capable of existing in more than one valency state, the liquid catalyst and reactants being passed through the reaction zone in the same direction at a high velocity, so that the velocity of the heterogeneous system is at least at some places greater than the relative velocity of the catalyst liquid and the reactants that would be reached at the flooding point if they were flowing in countercurrent under otherwise identical conditions.  The process can be used for the treatment of olefines mixed with saturated hydrocarbons or of mixtures of olefines. Advantageously a catalyst containing a noble metal in addition to the metal capable of existing in more than one valency state is used.  Preferably a catalyst containing a palladium compound and a copper compound is used and it may also contain iron, chromium, manganese or cerium compounds. Suitable anions are, for example, halogen ions, chlorate, perchlorate, or nitrate ions or mixtures of these with sulphate or acetate ions.  In addition where chlorine ions are present in the catalyst, compounds which yield chlorine ions, e.g. acetyl chloride, ethyl chloride, tertiary butyl chloride and bromine trichloride may be added to the reaction mixture.  To raise the pressure of water vapour substances, e.g. metal salts capable of raising the boiling-point may be added to the catalyst.  The process may be used for converting ethylene to acetaldehyde and acetic acid, propylene to methylethyl ketone, butylenes to methylethyl ketone, butyraldehyde or isobutyraldehyde, and butadiene to diacetyl and crotonaldehyde. Specifications 898,790, 900,829, 922,694, 938,831, 938,832, 938,833, 938,834 and 938,835 are referred to.
Patent GB-744482-A (GB)
Title: Improvements in or relating to crystallization process
IPC: B01D9/00
Filed: 1953-01-09
Abstract: In processes in which crystals are obtained from a hydrocarbon mother liquor, e.g. in the dewaxing of mineral oil, the liquor is agitated during the formation of crystals by pulsating it at the rate of 20 to 300 pulses per minute, successive pulses being directionally opposite to one another and each pulse imparting a uniform flow <PICT:0744482/III/1> <PICT:0744482/III/2> movement of between 1/4 and 4 inches to substantially the whole liquor mass.  In the evaporative batch type crystallizer of Fig. 1 liquor from a storage tank 120 is pumped to crystallizer 101 where evaporation of solvent occurrs either by heating, e.g. by steam coil 110, or by pressure release accompanied by auto-refrigeration as in the conventional solvent dewaxing technique.  Make-up solvent may be added at 136.  The liquor in the crystallizer is caused to pulsate as a whole by means of a partition 102 and reciprocating flapper valve 107 which alternately allows each of the compartments 103, 104 formed by the partition 102 to communicate with the take-off pipe 105.  Slight auxiliary agitation of the liquor is effected by stirrers 109. When sufficient crystallization has occurred the mother liquor and crystals are separated at 133.  For dewaxing, the hydrocarbon liquor with 0.2 or less volumes of solvent per volume of feed stock may initially be cooled by auto-refrigeration to below the cloud point (60-100 DEG F.) without agitation, the full amount of solvent added and the mixture cooled to between 0 and -40 DEG F. with pulsation.  In continuous crystallizers, e.g. double-pipe heat-exchangers, pulsations applied directly to the flowing stream, and may be obtained by providing an appreciable time interval between successive strokes of a reciprocating feed pump, by alternate fast and slow or large and small strokes, by reciprocating slide valves in conjunction with surge chambers or, as shown in Fig. 2, by reciprocating pistons which alternately inject and withdraw slurry from the system.  Solvent and oil are independently fed to the system, mixing at 5, and the mixture is cooled in scraped drillers 6, 7 and 8, additional solvent being added at 30.  The liquor is pulsed by a pulsator 9 and if necessary, additional pulsators 10, 70.  After crystallizing, the oil and wax are separated and passed to solvent recovery systems. Solvents referred to are propane, methylethylketone, methylbutylketone, di-ethylketone, sulphurdioxide-benzol, chlorinated solvents, light hydrocarbons, and ketonearomatic hydrocarbon mixtures.  The Specification also describes a series of experiments with waxy oils to discover the effect on filter rates of pulsation rates and amplitudes, degree of agitation, method of adding solvent and washing.  The experiments were carried out in a 2 inch diameter U-tube having a reciprocating piston in one leg.  Each leg was 16 inches long and had baffles to produce turbulence.  The solvent was added in one batch or incrementally during the cooling period.
