Title: Improvements in or relating to a Method and Apparatus for Rapidly Determining the Gas Content of a Metal
IPC: G01N33/20
Filed: 1967-04-07
Abstract: 1,183,252. Photo-electric measurement of gas content of metals. CENTRALNY NAOUTCHNO ISSLEDOVATELSKY INSTITUT TCHORNOY METALLOURGY "I. P. BARDINE". April 7, 1967 [April 15, 1966], No. 16080/67. Heading G1A. The gas content of a metal is measured by photo-electrically detecting radiation, characteristic of the gas, obtained when a spark is produced between an electrode and the surface of a specimen of the metal. A specimen for analysis is obtained by taking a sample from a bath of molten metal which is being monitored, cooling the sample and cutting off a small element of e.g. 15-20 mm thickness using a known cutting tool. The specimen or element 11 is then placed over an aperture 3 in plate 2 of the apparatus shown in Fig. 2. The cut surface of the specimen is arranged to face a pointed electrode 5, the specimen being positioned eccentrically, so that rotation will align different points on the specimen surface with point 6 of the electrode. The specimen is held in position by a bar carried in notches 13 of two supports 14. An inert gas e.g. helium, argon, or nitrogen is passed through the enclosure 1, via inlet and outlet conduits 8, 10. A spark is formed for about 0À2 sec. between electrode 5 and the specimen 11, the radiation produced passing through window 17 and being formed into a spectrum by an optical system 18 and the spectral line for the gas of interest being detected by a photo-multiplier. A number of measurements may be made with the specimen rotated to allow examination of different points of the surface. The measurements are compared with a calibration curve obtained with standard specimens. The method and apparatus is applicable to the determination of oxygen in effervescent, semikilled or killed steels at the molten stage before casting.

Title: Improvements in or relating to machines for filling containers with liquid
IPC: H01M50/609
Filed: 1945-06-27
Abstract: 601,031. Filling containers with liquid. ROBERTS PATENT FILLING MACHINE CO., Ltd., BICKERSTAFFE, A., and EDGE, K. June 27, 1945, No. 16379. [Class 125(ii)] In a filling-machine in which containers are fed intermittently on an endless belt or chain beneath intermittently-opening filling nozzles, an apertured slide is provided which in one position disengages a valve-lifting member from the nozzle valves and in another position causes mutual engagement of these parts. As shown, zinc torch battery containers to be filled with liquid electrolyte are held in pairs side by side in sockets 29 on carrier plates 28 fixed to chain conveyer 1 which is driven intermittently by a ratchet and pawl device attached to sprocket 2 and operated by cam 12. Carrier plates 28 are supported on angle irons fixed to table 6, and chain tension is controlled by screw adjustment 5. The extended stems 23 of mushroom valves in outlet nozzles 22 are attached to carrier bar 24, Fig. 4. Rods 20 reciprocated by cam 19 pass through carrier bar 24 and engage a further bar 27 slidably attached thereto, thereby operating the valves against compression springs 25. Screws 20a provide lengthwise adjustment of rods 20. Cams 12 and 19 are chain driven from a common electric motor 8 and are so adjusted relative to their chain sprockets as to synchronise the release of liquid with the period of rest of chain conveyer 1. Machine stoppage with the valves open is guarded against by moving over the slide bar 27 prior to stopping the motor, so that holes in bar 27 register with those in bar 24, thereby disconnecting rods 20 and allowing the valves to close. Bar 27 may be moved by hand, or by means of a solenoid coupled to the stop-start switch of the motor. The open-topped tank 21 made of, or coated with, insulating material comprises side-byside storage and regulator compartments, with means for maintaining a constant head in the regulator compartment to which the nozzles 22 are attached. The tank and valve mechanism may be movable lengthwise of the table. In order to reduce the length of the filling pauses to a minimum, the valves may open just before the chain 1 comes to rest.

A moving-coil loud-speaker for use in transistorised equipment comprises an outer annular permanent magnet 3 having a soft iron plate 1 against one face and a centrally-apertured conical frame plate 4 against its other face, there being a cylindrical ferromagnetic core 13 mounted on plate 1 so as to be coaxial with magnet 3 and extending into the central aperture in frame 4. A conical diaphragm 6 is supported within the frame and carries a coil 5 which extends into the air gap between frame 4 and core 13. An inner annular magnet 7 is disposed as shown so as to increase the flux through the air gap and which together with a resilient diaphragm 8 and paper hood 9 also ensures a dust free enclosure for the air gap and coil. The central core 13 may be permanently magnetized as indicated by the arrow, the outer magnet may be composed of a plurality of sections arranged in the form of a ring and apertures 11  and 12 may be provided to reduce the stiffness of the air behind the diaphragm.

Title: Improvements in or relating to the production of metallic elements
Inventor: LOVE PHIL PRINCE
IPC: C22C1/08
Filed: 1950-07-04
Abstract: A method of production of metallic elements, such as plain bearings, comprises forming a composite material of Cu-Pb or Cu-Pb-Sn or Cu-Pb-Sn-Fe containing for example up to 30 per cent. of Pb. by a casting or sintering process on a ferrous or other backing, removing the lead at, or to any desired depth extending from the surface, by chemical or electrochemical action to leave a porous structure and thereafter filling the pores with a friction-modifying substance. The composite material may have unconnected Pb particles dispersed in a matrix in which case pores p  are formed at the surface, or the Pb and Cu matrix may form an interlaced reticulate, sponge like structure in which case Pb is removed entirely or to any desired depth from the surface.  If the composite material is produced by sintering a composite layer of powders comprising two or more strata of different compositions, the porous structure produced is graded or localised.  The pores may be filled with poly-tetra-fluoroethylene or other long chain polymerised fluorine compound.  Specifications 657,080, 657,085, 676,300, [all in Group XXXIV], and 677,240 are referred to.

Bearings, determining wirelessly; directive wireless signalling.-A directional transmitter emits waves having distinctive characteristics, for example wave-length, group-frequency or damping, for each direction of propagation. In one arrangement, a closed loop aerial 20, Fig. 1, rotates synchronously with the movable part of a variable condenser 21 in the oscillation circuit. The closed loop may be replaced by an open loop, and the inductance 23 may be varied instead of the condenser. In another arrangement, two fixed directional aerials 26, 27, Fig. 5, are connected to inductances 30, 31 at right angles, in the field of which a coil 32 rotates synchronously with a variable condenser 33 in the oscillation circuit. The aerials are preferably tuned by condensers 28, 29 to the mean of the wave-lengths produced in the circuit 32, 33, 34. In a modification, the circuits of the aerials 26, 27 include inductances or condensers which rotate with the condenser 33, so that the aerials remain in tune with the circuit 32, 33, 34. A series of directive aerials, each tuned to a particular wave length, may emit waves simultaneously or in succession.

[Also in Division G3] The pressure in a decompression chamber is progressively reduced at a desired rate between steps of a decompression programme, set up by a programming device on a diode matrix, by counting down a digital counter by the output pulses of a multivibrator having a time constant determined by an R.C. circuit with switchable resistors. The count in the digital counter, through a digital to analogue converter is compared with the actual pressure in the chamber, determined by a potentiometric device, in a comparator an output of which controls a valve. The stepping of the programme in the diode matrix is effected through a logic network, the counter being set up by pulses from the multivibrator under control of a digital comparator. A second output of the comparator operates an alarm circuit when the chamber pressure falls below the programmed value.
