Title: Improvements in or relating to devices for initiating rotation of, and/or continuingslowly to rotate a turbine shaft
IPC: F01D25/34
Filed: 1954-11-05
Abstract: 761,206. Turning-gear. SIEMENSSCHUCKERTWERKE AKT.-GES. Nov. 5, 1954 [Nov. 9, 1953; April 6, 1954; July 15, 1954; July 16, 1954], No. 32136/54. Class 7 (5). [Also in Groups XIX, XXVI and XXXIV] In a device for initiating rotation of, and/or continuing slowly to rotate a turbine shaft 1, comprising an oil-operated auxiliary turbine 5 co-axial with and arranged to impart rotational motion to the shaft 1, a pump 11 is provided for relieving the load on the shaft bearings 9 by introducing pressure oil into the bearings to cause the shaft to float therein. The turbine and generator shafts 1 and 2 'of a turbo-generator set are connected by a clutch 3 and run in bearings 9 and 10, respectively, which are relieved of load by oil supplied from a pump 11 ; the turbine wheel 5 mounted upon the clutch 3 is used to maintain rotation of the shafts after the turbine has. been shutdown, the wheel 5 having oil delivered thereto from an auxiliary pump 12 through a pipe 7 and nozzles 6. To effect rotation of the shafts from rest a greater torque is required and oil from a second pump, not shown, is also supplied to the nozzles 6 ; in the preferred form oil from the pipe 7 and a spring-loaded accumulator 16 is fed to additional nozzles 15 via a non-return valve 13 and a shut-off valve 14 which latter valve recloses when rotation of the shafts has been initiated whereupon the accumulator is refilled and the pump 11 shut down since the bearings are now automatically lubricated. The rotation of the shafts is maintained by the action of the nozzles 6. The conduits 20, 21 leading to the individual bearings 9, 10 are each provided with a non-return valve 17, 18, respectively, and are connected in parallel to a common pressure line 22 that is supplied from a reservoir 24 through an adjustable by-pass valve 23 which latter ensures the application of an equal pressure to all the bearings and before initiation of rotation permits an upward thrust to be given to the shafts to lift them from the bottom bearing shells; a throttle valve 25 is incorporated in the conduits leading to any bearing which is of smaller diameter than bearings 9 and 10 in order that the oil pressure thereat shall not exceed that of the larger bearings. Means for measuring the speed of the shafts is provided (see also Group XIX).

Abstract: 478,762. Shower-baths. KERR, P. W. Nov. 24, 1936, No. 32138. [Class 26] [Also in Group XXIII] A sheet-metal " receptor " or bottom portion 10 for a shower-bath cabinet has a floor 14, coated with porcelain enamel in which grains of sand are embedded to provide a non-slip surface. The surface may be formed by applying, e.g. by dipping or spraying, enamel material to the sheet-metal, and then distributing sand thereon and firing. If desired, the first coat of enamel may be dried or fired at 1600‹ F. and the sand is incorporated in a second coat of enamel which is sprayed on, a speckled effect being obtained by lowering the air-pressure in the gun. The coat is then dried and fired at 1500‹ F. The receptor is secured in position upon a support 13 by a bracket 16.

Abstract: 423,457. Spectacle lenses. WITHERS, J. S., 51, Chancery Lane, London.-(Singer, N. ; 119, West 57th Street, New York, U.S.A.) Nov. 20, 1933, No. 32367. [Class 97 (i)] Spectacle lenses with a number of fields of different lightabsorptive qualities are produced by grinding a laminated lens blank of concavo-convex form and comprising layers of glass of different light absorptive properties, the central portion of one or in some cases both of the outer layers being removed. The lens blank may be formed by securing layers of glass together by a flashing or fusing process and moulding the compound layer to a concavo-convex form as shown. The dotted line shows the extent to which the layer 6 of higher absorptive properties is removed by grinding to provide a clear central area with a full visual field. In a modification the layer of higher absorptive properties may be on the concave side of the blank and its central portion ground away from this side. The central portion of the lens may be tinted but to a lesser extent than the surrounding area. The light absorbent border to the lens eliminates glare due to reflected lightat the edges of the lens.

Abstract: 328,957. Clark, D'A. M., (Bendix Brake Co.). Nov. 6, 1928. F o r c e - transmitting mechanism. - In a fourwheel brake system, a pedal 38 is used to actuate all four brakes, while the rear brakes are independently operated by a hand lever 50; the idler levers used in the transmission swing horizontally about vertical pivots. These levers 30, 32 for the front brakes are connected together by a rod or cable 36, and those 42, 44 for the rear brakes by a rod &c. 48. The lever 30 is also connected by a rod &c. 56 to a channelshaped link 58, Fig. 5, pivoted on one rear lever 42. The hand lever acts on the lever 42 through a slotted link 58, which allows actuation of the rear brakes by the pedal without disturbing the handle. The link 58 acts as a one way connection to allow the rear brakes only to be applied by the hand lever 50. If the hand lever is mounted on the left side of the vehicle, it and the rod 56 are connected to the left lever 44. Where the propeller shaft during running moves through a big arc the cross rod 48 cannot be used; it is replaced by a bell-crank 62, Fig. 7, mounted on the transmission gear &c. and connected to the two idler levers 242, 244, by rods 64, 66. All the rods &c. connecting the levers and brakes are in tension.
Patent GB-677459-A (GB)
Title: Cellulose derivatives
IPC: D01F2/28
Filed: 1949-12-22
Abstract: Cellulose derivatives containing morpholinyl or C-substituted morpholinyl groups are produced by heating an organic sulphonyloxy compound of cellulose or of a cellulose ester or ether with morpholine or a C-substituted morpholine until substantially all the sulphonyloxy groups have been eliminated from the cellulose or cellulose ester or ether.  When a sulphonyloxy derivative of a cellulose ester is treated, the latter may be an ester of acetic, propionic, butyric, glycollic or benzoic acid; the ester may also contain the radicals of two carboxylic acids, e.g. acetic acid and propionic or butyric acid. Morpholine itself is preferred to substituted morpholines, but examples of the latter which may be used are those in which an alkyl, aryl or heterocyclic group, e.g. a methyl, ethyl, propyl, phenyl or furyl group is attached to a carbon atom of the morpholine molecule; such substituting groups may themselves by further substituted.  The process may be carried out at about 50-100 DEG  C. for about 1-3 hours and the nitrogen content of the final product is preferably 0.5-4 per cent.  The cellulose esters containing sulphonyloxy groups may be made by the action on a carboxylic partial ester of cellulose of an organic sulphonyl chloride, e.g. an alkyl or aryl sulphonyl chloride, particularly tosyl chloride (p-toluene-sulphonyl chloride).  In the example, 40 parts by weight of cellulose acetate having an acetyl content of 53 per cent (as acetic acid) dissolved in 226 parts by weight of pyridine is stirred at 20 DEG  C. with a solution of 45 parts of tosyl chloride in 98 of pyridine, 198 parts of acetone are added and the tosyloxy-cellulose acetate formed is precipitated by the addition of 1500 parts of water.  15 parts of the cellulose compound are then heated to 70 DEG  C. for 1.5 hours with 147 parts of morpholine, and the morpholinyl cellulose acetate formed is precipitated by adding water, washed and dried.  It has a nitrogen content of about 0.7 per cent corresponding to a practically complete replacement of the tosyloxy group by morpholine.  The dried product is dissolved in acetone and spun into yarn.  The products have a high affinity for and may be dyed with acid dyes, and examples are given of the dyeing of fabrics made from the yarn produced as above with such a dye and also with a dye suitable for cellulose acetate yarn.  Yarns and fabrics of the cellulose derivatives of the invention are said to be less subject to gas fading when dyed with dyestuffs suitable for cellulose acetate yarns than are dyed cellulose acetate yarns. Specification 507,722 is referred to.
