Title: Improvements in or relating to turbines
Inventor: GIESZCZYKIEWICZ STANISLAW MARI
IPC: F01D25/16
Filed: 1964-07-22
Abstract: 1,105,658. Fluid-pressure servomotor systems. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. July 14, 1965 [July 22, 1964], No.29590/64. Heading G3P. [Also in Divisions F1 and F2] A steam turbine plant has servo means by which at least one turbine cylinder and its rotor can be moved relatively to one another to maintain internal clearances. The plant has in flow series super-critical and higher pressure turbine cylinders SPC, HPC and intermediate and lower pressure cylinders IPC, LPC, the respective rotors SPR, HPR etc. being rigidly inter-connected by flanged couplings such as 21. A fixed thrust bearing 31 locates the rotors axially. The lower pressure cylinders LPC are contained within a casing 15 fixed by an anchor point 41 to the foundation 35. The cylinder IPC is also fixed to the foundation. In order to compensate for axial expansion or contraction of the rotors so as to maintain desired running clearances in the cylinders SPC, HPC, bearing housing 67 carrying rotor bearings 63, 69 is axially slidable on its support 81. Housing 67 is rigidly connected to cylinders SPC, HPC which are respectively connected to bearing housing 65 and axially slidable on an extension of bearing housing 73 so that axial movement of housing 67 effects corresponding movement of cylinders SPC, HPC. A sensor 85 detects axial movement of the rotor SPR. The sensor is in the form of a thrust bearing and comprises, Fig.2, a flange 83 on the rotor SPR co-operating with front and rear thrust pads 87, 89 respectively mounted on the housing 67. Channels 91, 93 communicate with ports in the pads 87, 89 respectively and with chambers on the opposite sides of pistons 97 in two cylinders 95, illustrated also in Fig.3 (not shown). Pumps 115, 117 supply oil to the front and rear chambers respectively. Rods 99, 101 extending from each piston 97 co-operate with fixed front and rear abutments 107, 109 on support 81. Thus axial movement of rotor SPR to the left causes flanges 83 to move against thrust pads 87 causing a rise in oil pressure in the chamber to the left of each piston 97. The increase in pressure forces rod 101 against abutment 109 and moves bearing housing 67 to the left carrying with it cylinders SPC, HPC so as to restore the axial running clearance in these cylinders. In a modification, Figs.4, 5 (not shown), the sensor 85 is positioned between the cylinders IPC and LPC, and actuates a piston (97) in a fixed cylinder (95'). Movement of the piston in response to axial movement of the rotor IPR detected by sensor 85 causes a-corresponding axial movement of bearing housing 73 and the connected cylinders HPC, SPC and bearing housing 67 which in this case carries the thrust bearing 31. Thus all the rotors are displaced axially to restore axial running clearances in the cylinders IPC, LPC.

Filed: 1931-10-28
Abstract: 391,461. Printing- machines. GREAVES, W., The Woodlands Shadwell, near Leeds. Oct. 28, 1931, No. 29892. [Class 100 (ii).] A rotary photogravure printing-machine of the kind in which a number of printing-couples are employed for printing in succession on a web, and in which one or more of the couples is reversible to enable the impression from any couple to be printed on the desired side of the web, is constructed with a common drive shaft 11 for the cutting-cylinder 13 and all the printing-cylinders 4, and a right-hand threaded worm 12, or a left-hand threaded worm 12a is provided for each worm wheel 13 on the cylinders, and either worm can be put into action according to the direction in which it is desired to drive the couple. The printing - plates o n the cylinders 4 are inked by means of rollers 5, Figs. 3 and 5, immersed in troughs 6, and are wiped by means of reciprocating scrapers 7, and the whole inking-apparatus can be adapted to an alteration in the direction of rotation of the cylinder 4, and also to co-operate with printing-cylinders of different sizes. The troughs 6 and rollers 5 can be supported on either side of the cylinders 4, and each roller 5 is driven from a gear 15 on the shaft of its cylinder 4 and intermediate gears 17, 18 and a gear 16 on the roller 5. The gears 17, 18 are mounted in a pivoted bracket 19 which can be secured on either side of the cylinder, and can be adjusted about the axis of the roller 17 so as to enable cylinders of different sizes to be employed. A screw 21 passing through a slot 22 holds the bracket 19 in the desired angular position. The scrapers 7 are attached to bars 23 secured to blocks 24 adjustably secured by screws 25 to the side frames of the machine. The scrapers are all vibrated by eccentrics on a shaft 26 and the eccentrics are adjustable axially of the shaft so as to act when the scrapers are on either side of the cylinder. The scrapers are detachably connected by swivels to the eccentric mechanism so tha't they can be tutned end-to-end when changed from one side of the cylinder to the other. The web 31 is led over freely mounted guide rollers 32 arranged at such distance apart as to enable the impression to dry before a subsequent impression is applied, and is registered and rolled as described in Specification 391,465. Each printing- cylinder 4 is mounted so that it can be adjusted laterally. The cylinder is splined to a sleeve 43, Fig. 5, secured to the worm wheel 13, and lateral motion of the cylinder is effected by a shouldered bolt 44 screwed into the end of the mandrel and held against lateral movement by a collar engaging at opposite sides of a boss on the wheel 13. The printed web is fed to the cutting-mechanism E by means of a roller 45 driven from the shaft of the cutting-cylinder through a slipping clutch which avoids the necessity of adjusting the cutting-cylinder to accommodate different lengths of sheets.

Title: Oxyalkylation of phenol aldehyde resins
Inventor: BATTY JOHN WOOLEY
IPC: C08G8/28
Filed: 1952-11-28
Abstract: Non heat-hardenable phenol-aldehyde resins are oxyalkylated by gradually adding a 1,2-alkylene oxide to an alkaline solution of a salt of the resin in water.  On the average at least one phenolic hydroxyl group/molecule is oxyalkylated and at least one left free. Suitable ingredients for the resin are phenol, cresols, p-tertiary butyl phenol, p-octyl phenol, bifunctional xylenols, resorcinol or diphenylol propane and formaldehyde, acetaldehyde or benzaldehyde. Suitable alkylene oxides are ethylene, propylene or butylene oxide. The salt of the resin is prepared by dissolving in, for example, sodium or potassium hydroxide.  If the salt is not directly soluble in alkali a watermiscible solvent, e.g. acetone or ethyl alcohol, may be added.  Using water alone as reaction medium the oxyalkylation product may precipitate before oxyalkylation is complete.  In Example 1 propylene oxide was bubbled into a caustic soda solution of a non-heat-hardenable cresol-formaldehyde resin at 85-90 DEG  C. until a soft resinous mass formed which was poured into HCl to neutralise the soda and precipitate a granular product.  Example 2 was similar using ethylene oxide and Example 3 describes the oxypropylation of a p-xylenol-formaldehyde resin.  Partially oxyalkylated derivatives of resins containing 3-8 benzene nuclei per molecule are suitable for reacting with epichlorhydrin as in Specification 746,824.

Title: Apparatus for detecting magnetic fields utilizing the hall effect
IPC: G01R33/07
Filed: 1957-09-30
Abstract: An insulating support carrying a deposit of semi-conductor material forming a Hall plate (see Group XXXVI), is made by the following steps.  The support, which may be of glass or quartz, is cleaned by successive washings in potassium dichromate, water, carbon tetrachloride, water, dilute hydrochloric acid and distilled water followed by ionic bombardment.  The surface to be coated with semi-conductor is then coated with a gelatin-like substance which polymerizes on exposure to intense illumination and a reduced shadow of a pattern of the same configuration as the desired deposit of semi-conductor cast on the surface.  The exposed parts of the coating are polymerized and the remainder of the coating is then dissolved in alcohol.  Germanium or indium antimonide is subsequently deposited by vacuum evaporation over the entire surface to a preferred thickness of from 0.1-2 microns and the material overlying the polymerized coating removed by treatment in warm sulphuric acid.  Germanium deposited in the above manner is amorphous and may be converted to crystalline P type by heating to above 500 DEG C. in hydrogen or helium.

Abstract: 1,144,783. Separating hydrocarbons. UNIVERSAL OIL PRODUCTS CO. 8 July, 1966, No. 30708/66. Heading C5E. [Also in Divisions B1 and G3] In a simulated moving bed process for separating hydrocarbons, the rate of fluid flow between a pair of conduits is maintained constant, despite the movement of the points of connection, by automatic control dependent on the rates of flow in the conduits. The control system may use electrical, pneumatic or hydraulic signals in analogue or digital form (see Division G3). The process is illustrated by separation of nfrom iso-hexanes using a molecular sieve sorbent, e.g. dehydrated calcium aluminosilicate, with n-butane as desorbant. Other applications mentioned include separation of benzene, toluene, xylene, polycyclic aromatics and cycloparaffins by means of molecular sieves; separation of benzene by means of a nickel cyanide/ammonia complex; and separation of straight-chain aliphatics by urea or thiourea adduction.
