Title: Improvements in safety devices for protecting the dead centres of machine tools
IPC: B23B23/00
Filed: 1950-05-19
Abstract: 676,666. Lathe details. ETABLISSEMENTS A. CAZENEUVE, and BRUET, H. R. May 19, 1950 [May 20, 1949], No. 12550/50. Class 83 (iii). The tailstock dead-centre 3 is held in working position by a torsion bar 11 connected at one end to a pinion 7 meshing with a rack 6 rigid with a tailstock slide 2 supporting the centre and at the other end to a disc 14 held in angularly-adjusted position relatively to the tailstock frame 20. The centre is adjustable in the slide by a wheel 4 and can be locked by a lever 5. A sleeve 8 on the pinion 7 may be rotated by gears 9, 10 to feed the slide relatively to the frame when cutting-tools are carried thereby. The centre is loaded against the work by rotating a handle 15 or wheel fixed to the disc 14 to twist the bar 11, the disc 14 being locked in adjusted position by a spring-pressed plunger 17 engaging notches in a disc 19 secured to the frame. A scale indicating the extent of the thrust on the centre is provided on a ring 22 fixed to a pin 23 secured to the sleeve 8, the pin being housed in a sector-shaped slot 24 in the disc 14 so as to permit rotation of the disc in relation to the pin. Upon thermal expansion of the work during operation, the slide is displaced and increases the angular deflection of the bar 11, this being registered by the resulting rotation of the ring 22 caused by the sleeve 8.

Title: An improved method of and means for vapourising anaesthetic liquids
IPC: A61M16/18
Filed: 1940-08-03
Abstract: 541,924. Vaporising anaesthetic liquids. MACINTOSH, R. R., MENDELSSOHN, K., and SALT, R. Aug. 3, 1940, No. 12561. [Class 81 (i)] [Also in Group XIII] Anaesthetic liquid such as ether contained in a chamber c is vaporised by the latent heat of crystallisation of a liquid e.g. calcium chloride, contained in a chamber d, which may be heated from hot water contained in a chamber e. The vapour emerges through a pipe g into which air may be admitted by a branch h. Air may be admitted to chamber c by a pipe f. Hot water is admitted to the bottom of chamber e by a pipe r. Thermometers s, m are provided. The water chamber may be omitted and the crystallise substance melted by an electric heater. In an additional chamber also warmed by melting crystals the anaesthetic vapour may be diluted with air, oxygen or other gas to prevent condensation.

Title: Improvements in controllers for maintaining proportionality or substantial proportionality between the variations of a pair of variables
IPC: G05D11/13
Filed: 1952-05-20
Abstract: 717,363. Pressure gauges. BABCOCK & WILCOX, Ltd. May 20, 1952 [May 22, 1951], No. 12743/52. Class 106 (2). [Also in Groups XXXVII and XXXVIII] Apparatus for maintaining proportionality between the quantity of pulverized fuel and the air supply to a furnace burner comprises electrical means for measuring the two quantities, and comparing them in a circuit which produces an output voltage which affects the speed of a motor controlling the fuel supply. The air supply is delivered by a fan 10, Fig. 1, through conduit 11, and the fuel supply is fed by a motor 60 through a pipe 16. The rate of flow of air is determined by a pitot tube arrangement comprising pairs of apertured tubes 13, 14, 13<SP>1</SP>, 14<SP>1</SP>; Fig. 2, across the direction of flow, the up pressure being delivered by a tapping 24 to the interior of a bellows 25 in a sealed compartment 26 fed with the down pressure by a tapping 23. Thus the expansion of bellows 25 is proportional to the rate of flow of air in conduit 11 and a similar arrangement causes a bellows 35 to respond to the rate of flow of fuel in pipe 16 Each bellows 25, 35, is attached to a magnetic plunger 29, 39 movable in energized coils 40, 45 which are connected in series with the primary winding of a transformer 50, 55 to produce a proportionate D.C. voltage across a resistor 62, 64 after amplification and rectification at 61, 63 respectively. The algebraic difference of these voltages; together with a bias voltage obtained from a potentiometer 67 across a battery 68 is applied as a control voltage to the motor 60 controlling the fuel feed, via leads 71, 72. The control circuits, Figs. 4, 5, are fed from secondary winding ST-1 of a mains transformer.T-1. The motor 60 has a shunt field winding SHF fed withthe rectified secondary voltage via diodes 86, and. a series field. winding SF in series with: the armature 60A fed from two thyratrons 90 whose anodes are connected to opposite ends of winding ST-1, the grid, potentials; being determined by the secondary winding ST-3 of a transformer T-3 whose primary winding PT-3 is the diagonal of a bridge 80 also connected across the winding ST-1, the bridge comprising three fixed resistors and a coil 84 which is the power coil of a saturable reactor having control coil 85. The control voltage at leads 71, 72 biases a valve 105 to control the anode current of valve 100, and hence the anode current of valve 110 having control winding 85 in its cathode lead. This in turn affects the impedance of power coil 84 in the bridge 80, to control the phase and magnitude of the current in primary winding PT-3 and secondary- ST-3, thereby controlling the conducting time of thyratrons 90, and hence the, average current through the armature 60A of motor 60. Relays A, B, C, D, E and F ensure proper time sequence of connections at starting, indicated by coloured lamps R, G. In a modification the control voltage is fed to the motor through two magnetic amplifiers.

Filed: 1927-05-18
Abstract: 290,442. Silva, F. A. de, and Carlisle, C. G. May 18, 1927. Extracting.-In a process for producing steel or steel alloys directly from titaniferous ores, the ores are first subjected to a magnetic concentration and the concentrate supplied with a reducing agent or agents to an electric furnace, the temperature of the bath in the furnace during the main portion of the reducing operation being controlled so that it does not exceed 1,600‹ C. whereby the titanium oxide passes wholly or mainly into the slag. The slag is then separated from the molten metal which is then refined to produce iron with any carbon content and by the addition of carbon with or without an alloying element converted into steel or alloy of any desired composition. The reducing agent may comprise crushed or powdered anthracite and lime or fluorspar and additional quantities of iron sands may be added during the reducing operation. The refining of the metal may take place in a separate furnace, and the furnace which is provided with overhead electrodes may be rotated during the reduction or the bath may be rotated relatively to the furnace. The proportions of the reducing agents may be altered so that a part of the titanium oxide is reduced to titanium which alloys with the iron. In an example the charge consists of 1,000 parts of concentrated iron &ands mixed with 200-330 parts of crushed or powdered anthracite and if desired with 70-75 parts of lime and 15-30 parts of fluorspar; or the lime and fluorspar may be added during the reducing operation. The production of chromium, nickel, silicon, manganese, tungsten, molybdenum , vanadium and cobalt steels is referred to. The titanium slag may be used for various commercial purposes. Specification 236,255 is referred to.
