Title: An improved construction of casing for hydraulic turbines and for other purposes
IPC: F03B3/18
Filed: 1925-05-13
Abstract: 254,464. English Electric Co., Ltd., and Seewer, P. W. May 13, 1925. Casings.-A spiral or volute casing for hydraulic turbines or pumps comprises a skeleton framework, or lattice, or hoop structure sufficiently strong to withstand the internal pressure, and a water-tight lining or filling not strong enough in itself to withstand the fluid pressure. Thus, a series of circular tension rods 25 or stranded cables may form a cage enclosing comparatively thin steel plates 20 which are butt-welded together and to flanges 8. The rods 25 are threaded through holes in the surfaces 9 of the flanges 8, and are secured by nuts 26, the inclination of the surfaces of each flange 8 being varied to agree with the varying diameter of the volute, so that the rods 25 may always embrace a section of circular shape. Guide vanes 18 connect the flanges 8 which are divided into three circumferential sections at the webs 6-7, 10-11, 12-13. The tension rods which may be spaced apart by plate strips or by wire, extend only from section I to section VIII, a tubular member 2 and riveted plates completing the structure as shown. In a modification, Fig. 6, a cast anchor ring 31 is used, the ends of the rods 25 being jagged and the ring 31 cast around them. The bent edges of the plates 20 engage the rings 31, and the combined structure of ring 31, rods 25, and plates 20 is bolted to the flange 8. Packing 35 may be introduced. Instead of the single lining 20, concentric layers may be used, the inner layer, for example, being of thin sheet copper and the outer layers of sheet steel or wooden planks. In place of a separate lining such as the plates 20, the rods or hoops 25 may be brought close together, the spaces between them being filled by plastic material or molten metal, or by pieces of metal secured by electric welding.

Title: Improvements in or relating to the desulfurization of organic compounds by hydrogen transfer reaction
IPC: C10G45/30
Filed: 1951-05-28
Abstract: Sulphur-containing organic compounds are desulphurized by mixing with naphthenes and heating the mixture at 750-950 DEG  F., in the vapour phase, in the presence of an activated carbon catalyst, and in the absence of extraneously added hydrogen; the naphthenes are thereby converted to aromatic compounds.  Naphthenes referred to are cyclohexane and methylcyclohexane.  Organic compounds specified are thiophene, alkylated thiophenes, diethyl sulphide, diethyl disulphide, dipropyl sulphide, dibutyl sulphide, diamyl sulphide, mercaptans and acids of sulphur.  The activated carbon may be derived from lignite, petroleum, coke, bituminous coal or pure organic compounds; the catalyst may be reactivated by stripping with a gas such as steam, nitrogen or flue gases at temperatures such as 1350-1600 DEG  F., or by burning off the deposits.  The process may be a batch or continuous process employing the catalyst in a fixed or moving bed or in a fluidized manner; a pressure of 1-100 atmospheres may be employed.  An inert diluent, such as a portion of the treated mixture, may be used.  The desulphurization may be effected in the presence of hydrogen acceptor compounds such as 2-butene.ALSO:Petroleum fractions such as naphtha are desulphurized by mixing with naphthenes and heating the mixture at 750-950 DEG  F., in the vapour phase, in the presence of an activated carbon catalyst, and in the absence of extraneously added hydrogen.

Title: Improvements in or relating to electromagnetic devices
IPC: H02K37/20
Filed: 1960-04-13
Abstract: 936,151. Electromagnets. GENERAL ELECTRIC CO. Ltd., and G. R. POLGREEN. April 13, 1961 [April 13, 1960], No. 13194/60. Class 35. An electromagnet device comprises a stator which includes an electric coil and a permanent magnet body formed of barium ferrite or like permanent magnet ceramic material and having polepieces, and a rotor, there being at least one angular position in which the rotor provides a path of low reluctance to magnetic flux passing between the polepieces of the stator so that the rotor normally takes up this angular position or one of these angular positions, the arrangement being such that when an electric current is supplied to the coil to substantially reduce the effect of magnetic field due to the stator, the rotor may be readily rotated to a different angular position. In Figs. 1, 2 a shaft 1 carries a brass cylinder 2 which has four steel rotor poles 3. The stator encloses the rotor and is formed of two similar annular assemblies 4 which include an annular barium ferrite permanent magnet 5 in rigid or flexible form, two mild steel polepieces 6 with inwardly projecting pole faces 7 and a coil 8. The polepieces of the upper assembly 4 are removed 90 degrees from those of the lower assembly so that the rotor may have four possible rest positions although in the embodiment illustrated stops 9 are provided to limit the rotation to 90 degrees. The coils 8 are connected in series opposition and a current pulse weakens one magnetic field and aids the other, thus changing the position of the rotor. Current pulses need only be applied to move the rotor. In Figs. 3, 4 (not shown), a third assembly 4 is added to the stack, thus providing rest positions at 60 degrees apart. Any number of rotor or stator pulses may be used. Furthermore, if the rotor of one device is rotated by other than electrical means, the output from the coils may be used to drive a second similar device at a remote station.

Abstract: 406,157. Knitting. TEXTILE MACHINE WORKS, Wyomissing, Pennsylvania, U.S.A. May 6, 1933, No. 13255. Convention date, May 7, 1932. [Class 74 (ii).] A method of making a run-proof fabric on a straight knitting- machine with shiftable transfer points consists in spreading, portions of loops belonging to selected needles over other needles bv means of the transfer points. The operation may be performed on a sufficient number of needles to give a uniform effect as shown in Fig. 8 or on a smaller number to give a striped or zig-zag effect. The transfer points may be shifted by known mechanism. After the loops are engaged by the transfer points, the needles and points rise together to prevent the spread loops from leaving their own needles. The spread loops are given a twist as the needles descend below the knocking- over bits.
