Title: Improvements relating to the production of cast iron castings surface hardened or hardenable by the nitrogen hardening process
IPC: C23C8/00
Filed: 1934-03-19
Abstract: In the production of nitrogen hardenable cast iron alloy castings containing silicon, aluminium and chromium with or without other constituents such as nickel, molybdenum, copper or titanium, the castings are produced in a sand mould, and the alloy contains 2,5-4,0 per cent of carbon, silicon up to 1, 0,3-1,75 of aluminium, and 0,5-2,0 of chromium, the percentage of aluminium varying inversely with the total percentage of silicon nickel or other graphitizing elements and the percentage of chromium varying directly with the graphitizing elements so as to result in the production of a casting which either in the as-cast condition or after a short annealing is devoid of carbon in the graphitic form.  The content or combined content of nickel, molybdenum copper or titanium is not in excess of 3 per cent.  Prior to nitrogenizing, the castings are annealed at 850-1050 DEG  C. followed by slow cooling or are hardened by quenching from 800-875 DEG  C. in an oil bath or bath of molten salts at 150-200 DEG  C. and then reheated to 700-750 DEG  C.  The castings may also be malleabilized.  The castings may be nitrogenized by heating to 450-650 DEG  C. in ammonia gas.

Title: Improvements in and relating to switches operated by fluid pressure for controlling electrical circuits
IPC: H01H3/24
Filed: 1932-08-16
Abstract: 402,980. Momentary-contact switches. GROVES, W. W., 30, Southampton Buildings, London.-(Briggs Manufacturing Co. ; 11631, Mack Avenue, Detroit, Michigan, U.S.A.) Aug. 16, 1932, No. 8646/33. Divided on 402,551. [Class 38 (v).] A switch for momentarily closing the welding circuit of a portable welding apparatus such as described in Specification 402,551 comprises a piston 94 carrying a contact 91 adapted to be moved into bridging engagement with fixed contacts 85 against the action of a spring 98 when fluid is admitted behind the piston through an adjustable hole 103. Fluid is simultaneously admitted to the front of the piston through an adjustable hole 109 but owing to the chamber in front of the piston communicating through a hole 108 with a larger chamber 107 pressure in front of the piston takes time to build up and does not prevent the above movement of the piston. After a predetermined time, the pressure in front of the piston, which acts on a bigger area than the pressure behind the piston and is aided by the retractive spring 98, is sufficient to cause the piston to move back into its original position and break the circuit. The holes 103 and 109 both communicate with a passage which communicates through holes 104, 105 with a cylinder 67 containing a piston 58 which operates the welding electrodes 23, 24, and the arrangement is such that when by pressing a trigger 79 fluid is admitted into the cylinder 67 to operate the electrodes, it does not pass through the holes 104, 105, to operate the switch till the piston 58 has passed the holes 104, 105 in its stroke. The fluid escapes through a passage 83 when the trigger is 79 released.

Each switch may be connected to a low voltage relay (not shown) . connected across one coil of a, reversing contactor. Energization of either coil will operate a reversible electric motor to adjust the speed at which the wire is drawn off from a forcing machine, thus altering the thickness of the wire covering.
Patent GB-702108-A (GB)
Title: An improved method for chlorinating titaniferous material
IPC: C22B34/12
Filed: 1952-04-04
Abstract: For the production and volatilization of titanium tetrachloride from titaniferous material containing calcium or magnesium compounds, e.g. titanium slags, the material is admixed with sulphuric or phosphoric acid or anhydride in amount equal to at least 50 per cent. and preferably 100 per cent., of that required to react with all the calcium or magnesium compound, and the mixture is dried by heating, and chlorinated in the presence of a carbonaceous reducing agent to form the tetrachloride, and calcium or magnesium sulphate or phosphate.  The formation of calcium or magnesium chloride which is detrimental to the process is thereby avoided.  When sulphuric acid is employed, a major part of the calcium or magnesium sulphate may be removed by decantation or in solution in water.  The mixture with carbon is suitably chlorinated at 800-850 DEG C. by a fluidized solids technique, chlorine and carbon dioxide being used as the suspending gases. Specification 702,109 is referred to.

Title: Improvements in and relating to carburettors for internal combustion engines
IPC: F02M7/17
Filed: 1935-03-20
Abstract: 453,873. Spray carburetters. ARNOTT, F. H., Yewcroft, Bushey Heath, near Watford, Hertfordshire. March 20, 1935, No. 8705. [Class 7 (iii)] For starting or running when the engine is cold, a carburetter having a suction-controlled fuel orifice is provided with at least one additional or auxiliary fuel supply orifice and a valve device adapted to close off the end or ends of one or more passages leading from the atmosphere to the fuel supply conduit to the orifice or orifices, the valve being opened for normal running to render engine suction on the orifice or orifices ineffective. In addition to a main fuel nozzle 6, supplied through a passage 1b from a float chamber 10, fuel is fed from the float chamber through a passage 1c to an orifice 8b in a plate 8 having a central aperture 8a opposite the main nozzle 6. A second orifice 8b is symmetrically disposed in the plate 8 and the passages 1b, 1c are duplicated to permit the float chamber to be mounted on either side of the carburetter body 1, the chamber itself being attachable in any of four positions-to provide a downdraught, updraught or horizontal carburetter. The main nozzle discharges across an air passage 4 obturated by a piston 15 carrying a tapered needle 14 controlling the nozzle. The piston is actuated by suction applied to its cylinder 5 through a passage If terminating in a drilling 18b in a plug 18 which closes the top of the cylinder 5. A second passage if communicates through a bore 18a in the plug 18 and a passage 19a in the wall of a cylinder 19 secured on the plug 18 and this passage communicates suction to the top of a second piston 17 mounted on the piston rod 16 of the lower piston 15. The rod slides on ball &c. bearings 16a in a sleeve 16b loosely held in a tube 16c secured to the plug 18. Air passages 1g, 18c, 19d lead from the conduits 1c of the auxiliary fuel orifices 8b to the top of the cylinder 19 and are controlled by a disc valve 20 which also controls a port 19c in the top of the cylinder. At starting, the valve 20 is turned to close the passages 19d and open the port 20, suction being then .operative to draw fuel through the orifice 8b and the suction on the piston 17 being destroyed to weaken the lift of the piston 15 across the air passage. The fuel supply to the main nozzle may be aerated through a passage 1d controlled by a screw 21.

Title: Improvements in or relating to transistor rectangular-wave generator circuits and the like

Filed: 1954-03-29
Abstract: 767,727. Transistor pulse generating, single and two stable state circuits. MULLARD RADIO VALVE CO., Ltd. Feb. 1, 1955 [March 29, 1954; June 11, 1954], Nos. 9123/54 and 17224/54. Class 40(6) In a circuit with loads RC, RE in the collector and emitter leads of junction transistor T1, Fig. 1, the collector is connected over a D.C. coupling to the base of junction transistor T2, a further impedance RX being connected between the emitters. If the impedance includes a D.C. path the circuit may be listable, a monostable or astable circuit resulting from the employment of a capacitor without D.C. path. In one of the two stable states, transistor T1 is fully conducting and all the electrodes are near earth potential. Due to the further potential drop across resistor RX the effective emitter-base potential of transistor T2 is very small and the transistor is nearly cutoff. In the other state, transistor T2 is fully conducting, the emitter current being sufficiently great to bias the emitter of transistor T1 , below earth potential so that the transistor is cut-off. Assuming transistor T1 to be on, the circuit may be triggered by negative pulses in the loop T1, T2, RX or by a positive pulse applied over the resistor Rb, the circuit being reset by pulses of the opposite sign A square wave may be derived from the emitter of transistor T2 and a wave of opposite sign from a load in the collator circuit. A capacitor Ce may be included to speed up the response of the circuit and an impedance having a D.C. resistance may be included between the collector of T1 and the base of T2. The emitter of transistor T2 may be returned to earth over resistor Rg, Fig. 2, and resistor RX omitted. If resistor RC is so great that transistor T1 is saturated then the circuit is mono-stable with transistor T1 in the on condition, while if transistor T1 is not saturated, the circuit is astable. The collector of transistor T1 may be connected over a diode to a potential intermediate earth and -EC to prevent the storage of holes, and a load may be included in the collector lead of transistor T2. In a modification, Fig. 3 a single source of positive pulses is applied over capacitors Cl, C2 and a steering network of diode D1, D2 to trigger and reset the circuit. With transistor T1 conducting, diode D2 is biased off and a negligible bias exists across diode D1 so that the circuit is triggered to the opposite state. With transistor T2 on, the emitter potential is low so that diode D1 is biased off, only a small bias existing across diode D2. The next input pulse is effective over diode D2 to reset the circuit to its original condition.
