Title: Improvements in or relating to steam turbine installations
Inventor: COWLISHAW DAVID
IPC: F01D25/28
Filed: 1965-07-23
Abstract: 1,137,272. Steam turbines. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. April 28, 1966 [July 23, 1965], No. 31478/65. Heading F1T. A sub-frame carrying H.P. and I. P. steam turbine cylinders is aligned at site relative to an L. P. unit and then secured to the L. P. unit in aligned position by the engagement of part-hemispherical members 71 each with the part-hemispherical surface 79 of a corresponding socket 77. Each member 71 is attached by bolts 75 to one of a pair of vertical box girders 51 which are used for stiffening the end of the L. P. unit, with a spigot 69 engaging a hole 65. Socket 77 has a spigot 81 engaging a hole 83 in a plate 60 on the sub-frame. In practice, hole 83 is found to be eccentric to hole 65 when the sub-frame has been aligned relative to the H.P. unit. This eccentricity is measured and the periphery of the spigot 81 is finish machined with the same eccentricity relative to the axis of the surface 79. Alternatively, the hole 83 is finish machined to remove this eccentricity. In addition, the correct axial position of the socket 77 is ensured by machining the surface 91 of an overthick flange 77F to an appropriate thickness A or by packing shins between an overthin flange 77F and the plate 60. The socket 77 is secured to the plate 60 by bolts 85 and to the guides 51 by bolts 87. Ample clearance is necessary between bolts 87 and holes 89. These on-site adjustments of position may be made to the members 71 rather than the sockets 77.

Title: Autlmatically operating on a workpiece with a plurality of  cutting or forming tools
IPC: G05B19/416
Filed: 1973-07-02
Abstract: 1437794 Machine tool control SIEMENS AG 2 July 1973 [30 June 1972] 31505/73 Heading B3B [Also in Division G3] In forming of a workpiece with a plurality of tools, a priority tool is controlled to tend to keep a parameter (cutting force) of its operation at a desired value, the other tools being controlled in dependence on a desired total performance parameter for all tools (spindle torque). As shown, material is removed from workpiece 9 by the tools 16, 17 of a numerically controlled lathe according to the following scheme of constraints: (a) traverse velocity and/ or cutting depth for the tools is increased if the actual cutting forces, S k1 , S k2  measured by piezoelectric transmitters (not shown) are less than corresponding limit values S k1p , S k2p , or decreased otherwise, provided that the measured spindle torque Md is less than limit value M dp ; (b) should the torque limit M dp  be exceeded tool 16 is regarded as "preferred" and controlled as before, the limit value S k2p  for tool 17 being replaced by a new limit, where r 1 , r 2  are the effective cutting radii of the tools, S k1  being actual cutting force of tool 16. Should the traverse velocity of tool 17 fall below a predetermined minimum, the constraint S k1p  is replaced by a lower value, or the cutting depth of tool 16 is reduced. Control system.-Tape reader 19, or a computer (not shown) provides part data to numerical control system 1, receiving feed and traverse values, from units 3, 4 and derived as a result of comparisons of torque and cutting force limit and actual values in comparison units 7, 5, 6. Servomotors 12-15 drive tool slides 11, 10. Intermediate traverses of the workpiece are under control of the constraints. The separation of the two tools is kept above a minimum value by means of limit switches, or the monitoring of actual tool separation under computer control. Should the minimum separation be attained one of the tools has priority in its further motion. Tool length data may be fed in via thumbwheels, or is read from data on the tool shank read off at tool insertion, as can be permissible cutting force, and velocity, for the tool. The tool shank data may represent an address in the computer storing all the above data for each tool.

Title: Process for the manufacture of ortho-aminoarylmercaptans
Filed: 1927-11-23
Abstract: 306,590. Carpmael, A., (I. G. Farbenindustrie Akt.-Ges.). Nov. 23, 1927. Samples furnished. o-Aminoaryl-mercaptans and thioglycollic acids. -o-Aminoarylmercaptans are produced by heating 2-aminoarylthiazolic compounds with caustic alkali solution. The reaction is particularly adapted for treating the thiazolic compounds produced according to Specification 295,295, in which the position para to the nitrogen of the thiazole ring is occupied. An organic diluent, e.g., alcohol, may be present and the o-amino arymercaptans, which may be isolated as alKali or zinc mercaptides may be condensed with chloracetic acid to give o-aminoarylthioglycollic acids. According to examples, 2-amino-4- methyl-6-chlolorbenzthiazol, 2 - amino - 6 - ethoxy benzthiazol and 2-amino-4 : S-benz-6-ethoxy or methoxy-benzthiazol are thus treated with caustic alkali and by coupling the resulting mercaptans with chloracetic acid, converted into the corresponding o-aminoarylthioglycollio acids. The oaminoarylthioglycollic acids yield inner anhydrides and mav be isolated as such. 2-Amino-4: 5-benz-6-methoxybenzthiazol is prepared by treating 1-amino-4.methoxy naphthalene with an inorganic sulphocyanide in the presence of a halogen.

Abstract: 1354165 Marking gelatine layers with ink containing a hydroxyalkylformamide AGFAGEVAERT AG 8 July 1971 [11 July 1970] 32089/71 Heading G2X [Also in Division C4] Gelatine layers are marked by applying thereto an ink mixture comprising a hydrophilic dye which does not diffuse in gelatine, dissolved in a solvent comprising at least one hydroxyalkyl formamide wherein R 1  is a straight or branched chain C 1 -C 6  alkylene radical, and R 2  is H, a straight or branched chain C 1 -C 4  alkyl, a straight or branched chain C 1 -C 6  hydroxyalkyl, or a straight or branched chain C 1 -C 6  formylaminoalkyl radical. When applied to gelatine layers of photographic materials the ink produces a mark which is resistant to various photographic baths. The dye is particularly an azo dye which may be used for the silver dye bleaching process, preferably a polymer dye obtained by diazotization of amino-hydroxynaphthalene sulphonic acids followed by self-coupling in an alkaline medium. The mark may be applied by a felt tip pen, rubber stamp, typing ribbon or printing cloth. The formamide solvent is removed from the gelatine in the aqueous photographic baths, thus securing the dye to the gelatine layer. The process may be used to mark the upper surface of a photographic material, but more preferably a rear gelatine surface, particularly a layer containing 3-18 per cent by wt. of cellulose triacetate and 1-6 per cent wool fat, based on the dry weight of gelatine. In addition the layer may contain barium sulphate, strontium sulphate, silica or starch matting agents. In Examples a typing ribbon is used to apply the mark.

Filed: 1967-07-17
Abstract: 1,176,954. Luminescent materials. GENERAL ELECTRIC & ENGLISH ELECTRIC COMPANIES Ltd. 17 July, 1967 [17 July, 1967], No. 32689/67. Heading C4S. [Also in Division H1] In a L.P.M.V. fluorescent discharge lamp containing a rare starting gas at a pressure of a few mm. Hg and designed to have, in normal operation, a power loading not exceeding 0À4 watt per sq. inch of the internal surface of the envelope, the coating on the internal surface includes, dispersed in association with the fluorescent material, one or more of the metals Cu, Ag, Au, Zn, Al, In, Tl, Sn, Pb, Bi, Fe, Co, Ni, in the form of a finely divided powder and in a total amount not exceeding 0À3 gram atom per gram atom of mercury present within the envelope. The metal forms an amalgam during processing or initial operation of the lamp to reduce the mercury vapour pressure in operation. The powder may be uniformly dispersed in the fluorescent material or as a separate layer between the fluorescent material and the envelope. The preferred metals are In, Sn and Pb, which do not oxidize during baking, in particle sizes of 10-50 Á and in an amount sufficient to amalgamate with substantially all of the mercury present. The powder is dispersed in a suspension of fluorescent material in a liquid medium containing a binder, e.g. nitrocellulose in butyl acetate or an aqueous solution of polyammonium methacrylate, or separate suspensions are initially made up and then mixed. The combined suspension is applied to the envelope and dried and then baked to remove the binder. Alternatively the separate suspensions may be applied successively to form separate coatings which are baked to remove the binders from both coatings simultaneously. An example is given of a lamp containing mercury and argon at a pressure of 2À5 mm. Hg and coated with a layer of halophosphate phosphor containing In powder in an amount of 0À11 gram atom per gram atom of mercury.

Title: Improvements relating to protective equipment for nuclear reactors
Inventor: NYE ANTHONY EDWARD THOMAS
IPC: G21D3/04
Filed: 1956-10-26
Abstract: 834,908. Nuclear reactors. BRITISH THOMSON-HOUSTON CO. Ltd. Oct. 8, 1957 [Oct. 26, 1956], No. 32729/56. Class 39(4). A gas cooled nuclear reactor having a number of coolant passages each provided with an independent circulator is provided with protective equipment comprising a normally unbalanced electrical bridge circuit, means for varying the resistance of a first arm of the bridge each time the failure of a circulator occurs in a manner tending to balance the bridge, and means for adjusting the resistance of a second arm of the bridge to select the value of the resistance of the first arm required to effect balance of the bridge, the arrangement being such that under normal conditions out of balance current in the bridge circuit flows through the actuating coils of relays so as to hold in the relays while when the out of balance current has been reduced to a value corresponding to the failure of the preselected number of circulators the relays are released to effect a shut down of the reactor. The bridge circuit in Fig. 1 is for a reactor having eight circulators, and a resistance r4 is provided for each circulator and is connected in circuit by either of two relays, one responsive to coolant mass flow and the other to direction of coolant flow. A second arm of the bridge comprises two resistances r3, one or both of which is connected in the circuit according to whether the circuit is to be responsive to the failure of one or two circulators. The polarised relays CDR1, CDR2 operate and shut down the reactor when the bridge is balanced. Fig. 2 shows the circuit for the relays responsive to mass flow. Pressure signals obtained from the gas ducts are fed to transducers T the outputs of which are fed to one side of the polarised relays, the other sides of the relays being connected together. Thus when the outputs of the transducers are all equal there will be no circulating current, but if the output of one falls circulating current flows in associated relay and closes the contacts in Fig. 1. Since these relays are normally deenergised they do not fail safe, and for this reason the second set of relays in Fig. 1 is provided, these relays being connected across an orifice face in the ducts or across the bent exchanger and operating in the event of a reversal of gas flow.
