Title: Process for deoxidizing steel
IPC: C21C7/06
Filed: 1932-06-30
Abstract: In a process for deoxidizing steel by means of a molten non-basic oxide-extracting slag, the slag is used in such fluid condition and the slag and molten metal are subjected together to such violet turbulence that an emulsion-like mixture of slag and metal is produced.  The metal may be rapidly poured on to a very fluid slag or the latter may be poured into the mixing receptacle simultaneously with the rapid pouring of the metal.  The slags used comprise silicic acid lime and alumina rendered very fluid by the addition of soda or silicia acid lime and soda.  The slag after use is revivified for further use by treatment in a furnace with a reducing agent, e.g. carbon and the molten metal may be recarburised prior to treatment with the slag.  The purified metal may be treated with small proportions of aluminium in the ingot moulds.

Title: Improvements in regenerative coke ovens
IPC: C10B21/24
Filed: 1923-07-20
Abstract: 217,454. Baglin, C. A. July 20, 1923. Coke ovens.-In a vertical flued regenerative coke oven having heating-flues connected in pairs for reversible operation, the gas and air supplied are so arranged that in one phase of operation combustion is effected in both flues of a pair, while in the other phase combustion takes place in one flue only, the other flue being utilized for the supply of air. As shown in connection with an oven in which the paired flues F, L are arranged transversely of the heating-wall, gas is supplied through a conduit I to the lower ends of the flues F, and through the nozzles 0 to the tops of the flues L, each flue being also connected at its lower end to one or other of the regenerator chambers D, R. In one phase of the reversible operation air is supplied through the regenerator D, and, say, three-quarters of the gas through the conduit I and the remainder through the nozzles O. Combustion takes place in both flues of the pairs, and the products escape through the regenerator R. In the other phase air from the regenerator R passes upwards through the flues L and meets the whole of the gas supplied through the nozzles 0, combustion taking place in the flues F and the products escaping through the regenerator D. The gas and air supply systems are preferably divided so that the firing of the two halves of the length of a heating-wall can be independently controlled. When the upper and lower gas supplies are both drawn from the same main the pipe for the upper supply is branched near its lower end, and three reversing valves are fitted for each unit of the gas supply system, one for controlling the lower supply, and the other for delivering full and reduced supplies at the top. The invention is also described in connection with an oven in which the connected pairs of flues are arranged longitudinally in the heating-wall.

Abstract: 720,174. Lubricating. TECALEMIT, Ltd. May 27, 1952 [Aug. 10, 1951], No. 18913/51. Class 12 (3). [Also in Group XXIX]. In a liquid or lubricant distribution system an injector unit comprises the combination of a metering device of the type comprising a relatively long bore of capillary dimensions connected at one end to a source of liquid supply under pressure, and means for receiving a measured quantity of liquid from the supply line before it is fed into the metering device, for subsequent discharge to a bearing or other place for use. Embodiments of the invention are described utilizing several of the metering devices described in Specification 706,175. In the construction shown in Figs. 2 and 3 the metering device 3 is located in a housing 2 which communicates through a passage 21 with a cylinder 5 containing a piston 6. The part 8 of the injector unit between the housing 2 and the cylinder 5 is bored to receive an oil inlet tube 10 adapted to receive pipe unions 12, 13. The tube has an annular recess 14 and radial ports 15 through which, and past a spring-controlled valve 19, oil is forced into the cylinder 5. The cylinder has a hollow screwed cap 22 which has a tubular stop collar 24 forming a guide for a stem 25 on the piston 6. The piston' is urged downwardly by a spring 23, and its outward movement is limited by the stop collar 24. The stroke of the piston may be varied by adjustment of the cap 22. The quantity of oil which the cylinder 5 holds is indicated by a graduated longitudinal strip 27 which is bent over at the top to limit the outward movement of the cap 22 by engaging with a flange 26 thereon. Loosening of the cap is prevented by a blade spring 31 with a pointed end which engages in a knurled part of the cap. The top of the cap may have a transparent lens 22a so that the end of the piston stem 25 may be observed when the cylinder 5 is filled with oil. A number of injector units may be connected in series and the oil supply line may be connected to a pump driven manually or by an electric motor. 'The motor may be started and stopped by a pressure-controlled switch whereby when all the cylinders 5 have received the predetermined quantity of oil, the oil pressure rises and causes the switch to open and the motor to stop. The oil is then gradually discharged from the cylinders by way of the passages 21 and the metering devices to the points to be lubricated.

Title: Omni-directional radio beacon system
IPC: G01S1/02
Filed: 1955-07-04
Abstract: 777,530. Automatic phase-control systems. STANDARD TELEPHONES & CABLES, Ltd. (International Telephone & Telegraph Corporation). July 4, 1955, No. 19322/55. Class 38 (4). [Also in Group XL (c)] In a receiver for use in a phase comparison radio navigation system (see Group XL (c)), the received signal, Fig. 1B (not shown), comprises a pulse train of high recurrence frequency and two intercalated trains of N and S reference pulses 28 and 29, each of lower recurrence frequency, e.g. 30 c/s., the pulse signals being amplitude modulated at the frequency f and a harmonic thereof, e.g. 3f. The N and S reference pulses are extracted, Fig. 2 (not shown), and applied through a transformer 45 in opposite polarity to a sinusoidal oscillator 46 so that the output from oscillator 46 is synchronized with either one or both of the reference signals and in order to ensure exact synchronization the output from oscillator 46 is applied to the coincidence circuit 41, Fig. 2 (not shown), through a phase shifter 49 which is controlled automatically by a doublediode phase discriminator 50a, 50b. An output from phase shifter 49 is applied through an inverter 47 to the anode of diode 50a and the cathode of diode 50b and the reference signals are also applied to a thyratron 59 producing corresponding D.C. pulses which are coupled to the series connected primaries of transformers 60, 61 whose secondaries are so coupled to discriminator 50a, 50b that for each reference pulse a positive pulse is applied to the anode of diode 50a and a negative pulse is applied to the cathode of diode 50b, the amplitude of the applied pulses being greater than that of the peak amplitude of the sine wave from tube 47. The cathode of diode 50a is connected to the anode of diode 50b and the common junction is coupled to the phase shifter 49 over a pulsewidening network 55 having a time constant shorter than the periodic time of the sine wave. The phase shifter 49 is responsive only to voltages greater than the peak amplitude of the sinusoidal component of the output from the diodes. When correct synchronization obtains the reference pulses are coincident with the cross-overs of the sine wave output from phase shifter 49, the pulse outputs from the diodes cancel and no effective control voltage is applied to the phase shifter, but when this condition does not obtain then during one half-cycle of the sine wave the resultant diode output includes a pulse component of one polarity which adjusts the phase shifter 49 to reduce the phase error and in the next half-cycle the output includes a pulse component of smaller amplitude and of oppoaite polarity which adjusts the phase shifter in the reverse direction by a smaller amount, the process being repeated until synchronization is attained.
