IPC: F22B37/42
Filed: 1956-04-12
Abstract: 779,338. Indicating liquid levels. JERGUSON GAGE & VALVE CO. April 12, 1956, No. 11187/56. Class 123 (1). The water level in a steam boiler is indicated by a differential manometer M to the opposite sides of which are applied through conduits 31, 33 and 17, 25, 27, respectively, a variable head proportionate to the height of water and a predetermined constant head. As shown the pipe 17 enters a cup 15 which is supplied with steam from the boiler drum B after its passage through a condenser 19, the condensate in the cup 15 being maintained at a level H, preferably slightly above the high water level NHW, by an overflow 21 ; the pipe 17 is also surrounded by a jacket 23, extending down to the normal operating level, through which steam circulates so that the water in the pipe is maintained at the temperature of the boiler water. On the other hand the pipe 31 is connected to the drum B at an opening 29 at a level L which is at the same distance h below the normal operating level as the level H is above it. With the pipes 31, 33 and 25, 27 at atmospheric temperature, the arrangement is such that when the boiler water is at the operating level the manometer always indicates that fact at the same point on its scale whatever the temperature and pressure conditions within the boiler. In modifications, (1) the jacket 23 is dispensed with, the pipe 25 enters the boiler drum at the normal operating level, and the cup 15 and pipe 17 are disposed within said drum, and (2) the jacket 23 is again dispensed with, the pipe 17 entering the boiler drum at the normal operating level and returning at the same level L as the pipe 31.

Abstract: 513,597. Standard resistances. SULLIVAN, Ltd., H. W., and GRIFFITHS, W. H. F. April 14, 1938, No. 11492. [Class 37] The invention relates to A.C. standard resistances mounted within an electrostatic screen and wherein two methods of using the screen are adopted, namely: I. Connecting the low potential end of the resistance to the screen, II. Connecting the screen to earth and then arranging that the low potential end of the resistance is at earth potential but not joined electrically thereto. By using method II the capacitance from resistance to screen is eliminaated so that the residual inductance of the resistance is more positive than in method I. According to the invention, a two-way switch 8, Fig. A, is provided for connecting the low potential end of the resistance 3 to the screen 7 in one position thereof (method 1.) while in the other position thereof it disconnects the resistance from the screen (method II.) and connects a compensating condenser 9 or condensers across the resistance or one or more portions thereof, in order that the residual reactance of the resistance shall be approximately the same for both switch positions. Where the resistance is variable, e.g. in the form of decade resistance dials 11,-14, four separate switches or a fourpole-two-way switch a, b, c, d, Fig. B, is provided, which in the method II. position connects compensating condensers 21-24 across the respective resistance dials 11-14. In another embodiment, applicable to resistance dials; in each position 56-65 of the resistance dial arm 38, Fig. C, a corresponding compensating condenser 46-55 is inserted across the resistance provided the two-way switch e is in the position e<2> for method II. When a plurality of resistances are used some may be left uncompensated. The embodiments in Figs. B, C, may be combined, and the resistances may be variable by plugs.

Title: Static electrical converter with control
IPC: H02H7/125
Filed: 1975-03-21
Abstract: 1495762 Converting ASEA AB 21 March 1975 [22 March 1974] 11858/75 Heading H2F In a static converter means for measuring the load current comprises a D.C. measuring device 11 operable on the D.C. side of the converter 1, 2 and an A.C. measuring device 12, 13 operable on the A.C. side of the converter 1, 2, each measuring device being selectively connected so as to feed the largest output of the measuring devices to control means. The invention is applicable to a HVDC power transmission system in which the converter comprises a series-connected pair of bridges 3, 4. A signal dependent on the current in the D.C. line 9 is derived by means of a transducer or Hall generator 11, feeding a bridge rectifier 14. Signals dependent on the current in the A.C. side of the converters 1, 2, are derived from three-phase current transformers 12, 13 having respective bridge rectifiers 15, 16. Diodes 17 respond to the largest of these signals so that in the event of a fault in one of the current measuring devices, a signal is still available for comparison at 18 with a reference 19 so as to control the timing of pulses from a generator 20. In Fig. 3, the output of the respective bridges 14 ... 16 are fed to the inputs of operational amplifiers 27 ...29 including diodes 30, 31 in their feedback paths which provide an output at 18 dependent on the largest of the three inputs. In Fig. 2 (not shown) a similar result is achieved by connecting a bridge rectifier across the output of respective current transformers in each phase on the A.C. side, the D.C. side of the bridge rectifiers being connected in series so as to select the greatest current signal.

Title: Improvements in or relating to the treatment of articles formed of high temperature nickel-base alloys
IPC: C23C2/12
Filed: 1956-04-19
Abstract: A high-temperature Ni-base alloy article e.g. a turbine blade is coated with Al by either (a) removing surface oxide by dipping into a fused flux of KCl, NaCl, cryolite (Na3AlF6), and AlF3 and then dipping in molten Al, or (b) spraying on molten Al then dipping the article in the said fused flux; then after either step (a) or (b), reducing the thickness of the Al coating when the article is cool by immersion in a solvent (e.g. an acid), and finally heating to cause diffusion between the Al and the underlying metal.  The flux may comprise 37 to 57 per cent KCl, 25 to 45 per cent NaCl, 8 to 20 per cent cryolite and 0.5 to 12 per cent AlF3, may be activated by the presence of Al, and is used preferably at 1280 DEG  to 1400 DEG F. Molten Al when used as a dipping bath is between 1250 DEG  and 1325F DEG . and preferably contains 2 per cent Fe.  The solvent for reducing the thickness of coating is preferably an acid e.g. 10 per cent HCl; while the diffusion treatment is effected at 1700 DEG  to 2350 DEG F. for 1 to 6 hours followed by air cooling.  Preliminary cleaning may be necessary such as degreasing with molten electrolytic caustic salt at 900 DEG F. and water rinsing followed by pickling in an aqueous solution containing 2 per cent HF, 7 per cent H2SO4 and 10 per cent HNO3.  Parts not to be coated such as the root of a turbine blade may be stripped off with 20 to 50 per cent sodium silicate. After dipping in the molten Al the article may be re-dipped in the molten flux and may also be rapidly vibrated either whilst in the flux or after removal in order to remove excess Al coating.  It may also be vibrated in the flux after spraying.  Alloys referred to may contain 0.06 to 0.25 per cent C, 13 to 17 per cent Cr, 4 to 6 per cent Mo, 0.1 to 20 per cent Fe, 1.5 to 3 per cent Ti, 1 to 6 per cent Al, 0.01 to 0.5 per cent B, up to 1 per cent each of Mn and Si, with the remainder Ni; other Ni-base alloys, not within this range, are also set out in a Table.

Abstract: 1,055,845. Automatic control of speed and tension. AMPEX CORPORATION. March 22, 1965 [May 15, 1964, No. 11975/65. Heading G3R. [Also in Division H3| Tape tension in a television signal reproducing system is controlled by an electromechanical brake actuated by a signal derived from phase comparison of the reproduced line sync. pulses, at the end of each frame, with an oscillator whose frequency is arranged to correspond to the average frequency of the line sync. pulses. The system comprises a revolving disc carrying two record/ reproduce heads 24, 25, Fig. 1 (not shown), and magnetic inserts for tachometer pulses, in a cylinder 17, about which the tape is transported in a helical path. Head disc and capstan motors are retroactively controlled by a conventional system using a reference pulse oscillator with which tachometer and control track pulses are compared. For tension control, the frequency of a transistor oscillator 73 is controlled by the output of an averaging circuit 74, the input to which comprises pulses at line frequency and whose magnitude corresponds to the phase relationship of the reproduced line sync. pulses and the oscillator output. The comparison is effected at a symmetrical transistor 75, which is supplied with a sawtooth wave from a generator 100, 102, 103 triggered by the differentiated output of the oscillator 73 via a complementary emitter follower 80; the transistor 75 conducts to pass that part of the sawtooth obtaining when the line sync. pulse (differentiated at 72) is applied to its base. Tension errors result in a jump in the output of the comparison circuit at the changeover from one scanning head to the other and it is this which is used to operate the brake solenoid, after conversion to a D. C. signal and amplification at 83, and being further switched by tachometer pulses in a second symmetrical transistor 82. There is also a limiter stage 113. Tension is also adjusted by a purely mechanical system comprising a loop forming roller, the pressure on which acts in opposition to the solenoid; this has a faster response time than the electrical system.

April 23, 1931, No. 12084. Convention date, April 23, 1930. [Class 40 (v).] Relates to a directionfinding system of the kind in which two overlapping fields of radiation I, II, Fig. 1, are utilized to indicate to an aviator or other navigator a predetermined course along the line P, which forms the locus of the point of intersection of the radiated cones. According to the invention, the transmitting oscillator E, Fig. 2, is swung uniformly to and fro through an angle a, relatively to the focus of the reflector S, instead of being slowed down at certain points in the arc of swing, as in a known system, and a modulating note from a generator NF is superposed on the carrier frequency HF at one end of the swing by means of a contact K, so as to operate a separate indicator in the receiver with the object of showing the navigator his position relative to the median line P. The received signals are rectified by a detector D, Fig. 3, located at the focus of a reflector S<1>, and after amplification at V serve to swing an indicator needle J about a zero line. If the contact K is made when the transmitting oscillator E is radiating the field II, Fig. 1, and the receiver is moving along a line P2, the modulation note NF will be heard in the loud-speaker L, Fig. 3, when the indicator needle swings to the right-hand side, whilst if the receiver is moving along a line P3 the note is heard as the needle J swings to the left. The loud-speaker may be replaced by a flash-lamp. giving a visual indication of the modulation signal NF.
