Title: Improvements in or relating to combustion control
Inventor: MARTIN ALBERT EDWARD
IPC: G01N21/37
Filed: 1957-01-02
Abstract: 826,049. Automatic control systems for furnaces. GRUBB PARSONS & CO. Ltd., Sir H. Nov. 27, 1957 [Jan. 2, 1957; March 25, 1957], Nos. 190/57 and 9711/57. Class 38 (4). In a combustion control system for a furnace, signals indicative of the concentrations of CO and CO 2  in the exhaust gases are added in certain proportions such that their sum increases as the air/fuel ratio decreases, this ratio being varied automatically in dependence on said sum. In Fig. 2, infra-red heaters A periodically irradiate chambers E, E, containing a mixture of CO 2  and CO, through a rotating shutter S. In the absence of gas in chambers B, C, or D the gases in chambers E, E expand and contract equally under the influence of the intermittent radiation so that diaphragm F, forming a capacitor with perforated diaphragm G, does not vibrate. If a sample of the exhaust gases is passed into tube D, any CO 2  or CO present will absorb radiation and diminish that incident upon the corresponding chamber E, causing a change in capacity by the diaphragm movement. Furthermore to reduce the sensitivity to the CO 2  in the exhaust gases, i.e. to introduce a constant of proportionality, some CO 2  is sealed in tube C so that the subsequent absorption by the CO 2  of the test sample is reduced. A similar quantity of CO 2  is placed in tube B to compensate for the effect of that in tube C on the gas in chambers E. The variation of capacitor F, G is changed to an A.C. voltage variation, is rectified and applied to meter M, the pointer of which moves between upper and lower limit contacts P and Q. These are in circuit with solenoid-operated valves V 1  and V 2  which reduce or increase the air supply as appropriate. Instead of an analyser responsive to both CO 2  and CO two separate analysers may be used and their outputs electrically combined. Alternatively the analyser may be of the type to respond to radiation from the flame of the combustion process, the radiation being passed through selective filters and detected by a thermocouple, bolometer, semiconductive cell, photo-electric cell or magneto-photo-electric cell. In a further CO 2  analyser (Fig. 3, not shown) sample gas is divided into two paths in a desired ratio and in the path corresponding to the desired proportion of CO, first the CO 2  is absorbed and then the remaining CO is converted to CO 2 . When the paths combine in a CO 2  analyser the total CO 2  corresponds to the desired proportionate sum of CO and CO 2 .

Title: Process of manufacturing titanium metal with high creep resistance
IPC: C22B34/12
Filed: 1954-01-06
Abstract: Monosulphides of cerium (CeS), magnesium (MgS) and alkali earth metals (CaS, BaS, SrS) are prepared by reacting these metals with one or more sulphides of iron group metals in stoichiometric proportion. Cerium or its alloys, e.g. mischmetal, may be fused at 900-1600 DEG C. and the iron group metal sulphide added or the metal and sulphide may be comminuted, mixed and heated to the reaction temperature about 1000 DEG  C.  The reaction is carried out in vacuum or in a protective atmosphere of argon or under cover of charcoal or a low melting flux of halides of the alkali and/or alkali earth metals. The required sulphide can be separated by washing, flotation or magnetic separation.ALSO:In the manufacture of titanium having high creep resistance, ductility and anti-corrosivity the metal is melted in a crucible composed of or lined with one or more of the monosulphides of cerium, magnesium and the alkaline earth metals which have been prepared by reacting the respective metals with a sulphide or sulphides of iron group metals (see Group III).  Titanium treated in this manner may be comminuted to required grain size, preferably under oil cover to avoid oxidation, then exposed at elevated temperatures to oxygen and/or nitrogen or sulphur or to compounds of these elements such as moisture, ketones, sulphides, ammonia or amines to create a thin film of controlled thickness of oxide and/or nitride or sulphide on the surface of the grains and then compacted to produce shaped bodies.

Title: An improvement in coin or disc-operated locks for doors, drawers or shutters
IPC: G07F17/14
Filed: 1937-10-07
Abstract: 503,519. Coin freed locks. SALTMARSH, J, A. Oct. 7, 1937, No. 574. [Class 27] An existing key-operated lock is adapted for coin operation, and for use on a locker in which property may be left, by means of a separate coin-receiving device connectible therewith and controlling the lock in such a manner that (a) the lock cannot be operated or the key removed until a coin has been inserted, whereupon the lock can be operated once, the door opened and closed, and the key removed ; and (b) by reinserting the key the lock can be operated once to open the door, whereupon it returns to its initial locking position retaining the key. As shown, the device comprises a weighted slidable bar 24 working between guide plates 9 and pivotally connected with an arm 23 fast with the rotary barrel of the lock 1. A pin 25 on bar 24 normally seats in a recess 15 in the foremost plate 9 whereby the lock is held so that its bolt 3 is not fully shot. In this position, and with a lock of normal pattern, the key cannot be removed. Moreover, engagement of pin 25 with the left-hand side of recess 15 prevents turning of the lock to open the door in the absence of a coin. A coin inserted through a slot 8 comes to rest against an arm 19 on a plunger 18 and in slots 10 in the plates 9. On turning the key a curved edge 26 of bar 24 rides over the edge of the coin causing pin 25 to clear recess 15 enabling the bolt 3 to be withdrawn and the door opened. On releasing the key, the lock returns to a position in which its bolt is fully shot so that the key can be withdrawn, the pin 25 coming to rest in a recess 13 in an upper edge of the front plate 9 where it remains when the door is closed-to. To re-open the door the key is re-inserted and turned anticlockwise ; the bar 24 moves back to the left, and pin 25 engages under a wedgeshaped nose 21 on the plunger 18 causing the latter to rise so that its arm 19 releases the coin, the pin 25 finally falling on to a lower edge 16 on the front plate 9. On releasing the key, pin 25 returns into its normal position in recess 15, the lock being thereby held in a position in which the bolt 3 is sufficiently extended to lock the door but in which the key cannot be withdrawn without insertion of a coin.

Bearings.-Tiltable bearing blocks for radial thrust bearings wherein oil films are set up, are provided with holding devices for use during turning, cutting, grinding &c., whereby they are simultaneously held for treatment. The blocks 2, which rotate with the shaft, are of the type which are supported eccentrically of the shaft by a ring mounted thereon, and preferably have external spherical sliding surfaces. The support ring and adjacent surfaces of the blocks have projections and grooves to maintain the blocks in correct position. The blocks are formed from a ring of corresponding cross-section provided with wedge-shaped grooves 7 on its lateral faces. They are cut from this ring, hardened, and all those appertaining to one bearing are clamped in a holder. For interior treatment the holder. Fig. 5, comprises a member 9 provided with an annular inclined projection 10 engaging the grooves 7 and against which the blocks are pressed with a radial clamping action by a plate 12, having a similar projection 13, and screws 11. Plate 12 has a guiding rim 14. The clamp can be secured by a thread 16 to the spindle of a lathe or grinding machine. A similar clamp, Fig. 6, allows treatment of the exterior surface. Both clamping rings are radially slotted to provide resilient clamping. To obtain room for play of the blocks in their bearing housing, the diameter of the holding member 23 may be somewhat greater than that of the shaft upon which the blocks are to be mounted. A complete bearing is also shown and described.

Abstract: 531,067. Electron oscillators ; valve generating and modulating circuits. LELAND STANFORD JUNIOR UNIVERSITY, BOARD OF TRUSTEES OF. March 17, 1939, No. 982/40. Convention date, April 14, 1938. Divided out of 530,785. [Classes 39 (i) and 40 (v)] An ultra high frequency generator, in which changes in electron vector velocity are produced in a beam exciting a substantially enclosed resonant circuit, is controlled by causing the beam to excite a further circuit comprising a hollow resonator operating on a harmonic frequency. The Figure shows an arrangement in which back coupling of the enclosed resonant devices 104, 105 is effected by a further device 106 of lower frequency but operating at one of its harmonic frequencies. In this way the frequency is stabilized, as the Q of the circuit 106 may be higher than that of the circuits 104, 105. The output is amplified through a frequency multiplier 111 also co-operating with the electron beam produced by cathode 101. A further beam is produced by cathode 114 and co-operates with amplifying devices 112, 113 which feed an aerial 116. Modulation may be effected at any of the three tubes 117 and will give both amplitude and frequency or phase changes. The former may be suppressed by applying the modulating voltage to grid 121 through amplifier 120. Alternatively amplitude modulation may be applied to the grid 121 or to spaced plates 122 which deflect the electron beam. The plates 122 may be excited at the oscillating frequency and may be replaced by a deflecting resonant device as described in Specification 523,712 to increase the output. Amplitude modulation may be applied through transformer 118 between the electron source 114 and the resonant device 112. At frequencies of the order 1000 megacycles parabolic reflectors may be used. Specifications 517,264, 529,771 and 530,785 also are referred to.
