Title: Improvements in and relating to electric circuit controllers
IPC: H01H33/32
Filed: 1942-06-05
Abstract: 561,899. Controlling dynamo-electric machines. BRITISH THOMSON-HOUSTON CO., Ltd. June 5, 1942, No. 7695. Convention date, June 5, 1941. [Class 35] [Also in Group XXXVII] The series field of a generator is altered during starting by a controller comprising pneumatically operated switches. The controller comprises two cylinders 11, 12. The piston rod 43 of cylinder 11 carries a floating lever 44 which has contacts 45, 46 at opposite ends. A spring 50 biasses the end of the lever so that contact 46 is normally closed to fixed contact 29. When the cylinder 11 is operated to raise the lever the contact 45 first closes to fixed contact 19 and then the contact 46 opens. The piston rod of cylinder 12 carries a contact 41, which when raised closes with fixed contact 18. Contacts 29, 41 are connected to a conductive strip 51 by flexible leads. The needle valves 69, 68, Fig. 4, controlling respectively the admission of compressed air to, and its exhaustion from, the cylinder 12 are operated by an electromagnet 63 whose armature 65 moves the valve rod 67. A similar electromagnetic valve controls cylinder 11. In the circuit shown in Fig. 6, the fixed contacts 19, 29 are connected across a tapped portion 92 of the series winding of a generator 90 and the contacts 18, 41 are in series with a resistance 99. A controller 100 with overlapping cams 101, 102 operates the cylinders 11, 12 successively but in overlapping time relation. The successive connections are : (1) winding 92 short circuited, portion 98 in series with motor 93 ; (2) portions 92, 98 in series ; (3) portion 92 partly short-circuited through resistance 99; (4) portion 92 fully short-circuited ; (5) portion 98 in series. The battery 95 energizes the shunt winding 91 on pushing the button 96, so that the generator 90 acts as a motor for starting the prime-mover.

Filed: 1940-04-30
Abstract: 539,409. Magnetic bearings. SANGAMO WESTON. Ltd., and SNELL, M. S. April 30, 1940, No. 7786. [Class 12 (i)] [Also in Group XXXVI] A member which has a rotary or oscillating movement relative to a second member is supported with respect to the second member by both axial and radial magnetic repulsive forces which cause the first member to take up a stable position out of mechanical contact with the second member. In the electricity meter shown in Fig. 7 the driving disc 11. is mounted on a spindle 12 provided with permanent magnetic portions 14, 15 of the same polarity as corresponding fixed permanent magnets 8, 9 so that the rotating system is held out of actual engagement with the fixed magnets by repulsion. The magnet 9 is adjustable by means of a screw 10. The opposing surfaces of the fixed magnets 8, 9 and movable magnets 14, 15 may be conical with apical angles of valves governed by the relative values of the axial and side thrusts to be met or the magnets 14, 15 may be cylindrical or discshaped and co-operate with cylindrical recesses in the fixed magnets 8, 9. In a modification, Fig. 6, each magnetic element 2 carried by the shaft 1 is hollow and of conical shape with its top edge of one polarity and its bottom edge of opposite polarity. The fixed element 3 has poles of the same polarity as those on the rotating element. The spindle is of brass or other non- magnetic metal. The permanent magnets may be replaced by electromagnets, such an arrangement being shown in Fig. 8. The spindle 16, of ferro-magnetic material, is embraced by a coil 23 energized by a battery 24. The fixed pole pieces 20, 21 are joined by a yoke 22 magnetized by a coil 25 supplied by a battery 26.

Title: Improvements in the manufacture and production of valuable liquid fuels
IPC: C10G69/04
Filed: 1929-03-11
Abstract: 333,550. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). March 11, 1929. Mineral and tar oils, extracting and purifying; liquid fuel.-Liquid fuels are obtained from the high boiling constituents of distillable liquid carbonaceous materials, such as tars or mineral oils, or from the liquid products obtained by the distillation, destructive hydrogenation or cracking of coal, tars or mineral oils, by treatment with solvents to separate the initial materials into two portions, one richer and the other poorer in hydrogen, the second portion being then subjected to treatment with hydrogen under pressure, either alone or with carbonaceous substances, such as part of the first portion separated. to produce a non-knocking motor fuel. The first, portion is suitable as an illuminating or Diesel oil, either alone or after treatment with hydrogen under pressure at an elevated temperature. Preferably, substances of the nature ot middle oils are separated from the initial materials before treatment with the solvent, the constituents remaining after the removal of the middle oils being added to the, portion poor in hydrogen, if desired. Benzines, for example, may be obtained by subjecting the portion poor in hydrogen to destructive hydrogenation with mineral oil residues; these benzines may be mixed with other benzines such as those resulting from the destructive hydrogenation of brown coal rich in bitumen. Preferably the destructive hydrogenation of the parts poorer in hydrogen is carried out in the presence of catalysts, particularly those immune from sulphur poisoning and from the sixth group of the periodic system. As solvents for the separation, liquid sulphur dioxide or liquid ammonia., or a mixture of cyclohexane and methanol, or mixtures of all these may be used. In an example, a crude illuminating oil, obtained from the destructive hydrogenation of Columbia middle oil at 200 atmospheres and 425‹ C. in the presence of molybdic acid and zinc oxide, is separated by liquid sulphur dioxide into 60 per cent of a pure illuminating oil and 20 to 25 per cent of a product poor in hydrogen, mainly aromatic hydrocarbons. This product is added to the initial Columbia middle oil and the mixture subjected to destructive hydrogenation, benzines being obtained which are better as regards their antiknock properties than those obtained from the oil without the addition of the product poor in hydrogen. In a second example, a middle oil obtained by the destructive hydrogenation of brown coal is subjected to a second destructive hydrogenation at 200 atmospheres and 450‹ C. in presence of a mixture of molybdenum, chromium, and manganese oxides, and the higher boiling portions are treated with liquid sulphur dioxide, the portion poorer in hydrogen being destructively hydrogenated. In further examples the solvents employed are a mixture of methanol and cyclohexane and liquid ammonia and methanol respectively. Specification 300,900 (as open to inspection under Sect. 91 of the Acts) is referred to.

Title: Improvements in coloured textile materials
IPC: D06P1/56
Filed: 1947-03-25
Abstract: A water-soluble condensation product is formed from an aminotriazine such as melamine containing at least two hydrogen atoms attached to amino-nitrogen, an aldehyde and an alcohol, the preferred proportions and reagents being from 2 to 6 mols. of formaldehyde to each mol. of melamine, and at least one mol. of methyl, ethyl or propyl alcohol to each mol. of formaldehyde. The products may be mixed with a dye for application to cellulose ester or ether textile material which is subsequently steamed to render the condensation product insoluble. In an example, a paste comprising the dyestuff 1 - methylamino - 4 - (b  - hydroxyethylamino) - anthraquinone, methyl cellulose, water and the melamine condensation product described above is applied to cellulose acetate fabric by printing, and the fabric steamed at 106 DEG  C.ALSO:The resistance to combustion products of coal gas of a dye on a cellulose ester or ether textile material is improved by applying a water-soluble condensation product of an aminotriazine with an aldehyde and an alcohol, the aminotriazone containing at least two hydrogen atoms attached to amino-nitrogen, and thereafter rendering the product water-insoluble, e.g. by steaming.  The dye and the condensation product may be applied to the material either uniformly or locally.  The preferred condensation products are those obtainable by the simultaneous action of formaldehyde and methyl, ethyl or propyl alcohol on melamine, in which the proportion of melamine to formaldehyde is from 1 : 2 up to 1 : 6 and at least one molecular proportion of alcohol is used to each molecular proportion of formaldehyde.  Other aminotriazines specified are ammeline, ammelide, acetoguanamine and p  formoguanamine.  A small proportion of an acid or substance yielding acid on heating may be incorporated prior to application to the textile materials.  The process is of particular value when dyeing or printing with dyes of the 1-amino-4-hydroxy-anthraquinone and 1,4 - diamino - anthraquinone series.  Examples are given.

Filed: 1916-06-15
Abstract: 100,693. Ruths, J. C. June 14, 1915, [Convention date]. Generating by direct contact of steam with boiler water, by electricity and by reduction of pressure. - In electric generating systems in which the machines may be driven by water power wholly or in part with a steam-driven plant, to make the continuous firing of reserve boilers unnecessary in order to meet a breakdown of the power supply, the peak load or other disturbance, the load on such a disturbance is taken by a thermal-storage reservoir h containing water under pressure and at a corresponding temperature. If the disturbance is only of short duration, the reservoir is large enough to supply steam for the whole period; otherwise a reserve battery of boilers is used to supply the turbine. The water in the reservoir is heated by steam from the reserve battery of boilers, radiation losses being made good by an electrical heater. The Specification as open to inspection under Sect. 91 (3) (a) describes also an arrangement in which an electrically-heated storage vessel was used as a stand-bv without a reserve boiler battery. This subject-matter does not appear in the Specification as accepted.

Title: An improved method for chlorinating titaniferous material
IPC: C22B34/12
Filed: 1952-04-04
Abstract: For the production and volatilization of titanium tetrachloride from titaniferous material containing calcium or magnesium compounds, e.g. titanium slags, there is formed a mixture of the titaniferous material and titanium phosphate which is chlorinated in the presence of a carbonaceous reducing agent to form the tetrachloride and calcium or magnesium phosphate.  The formation of calcium or magnesium chloride which is detrimental to the process is thereby avoided.  The amount of phosphate present should be at least 50 per cent. of that required to react with all of the calcium or magnesium present.  The titanium phosphate employed may be formed by reacting phosphoric acid with the titanium slag, drying, and calcining at 800 DEG C.  The mixture with carbon is suitably chlorinated at 800-850 DEG C. by a fluidized solids technique, chlorine and carbon dioxide being used as the suspending gases.  Specification 702,108 is referred to.
