Title: Device for visualizing magnetic field patterns
IPC: G01D7/00
Filed: 1974-01-22
Abstract: 1452528 Visualizing magnetic field patterns PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 22 Jan 1974 [12 Feb 1973] 02854/74 Heading G1N Magnetic field patterns are detected by magnetooptically monitoring the cross-section of cylindrical magnetic domains which vary in accordance with the magnetic field applied thereto. The cylindrical domains 5, 5' are formed in a thin layer 3 of anisotropic material e.g. a rare earth garnet or othoferrite, formed on a layer 2 of a permanent magnetic material which maintains the domains. The device is positioned in the area of the field H to be monitored and a beam of polarized light from a laser and polarizer, Fig. 2 (not shown) scans, point wise, substantially vertically the tops of the domains in layer 3 through small holes 4, 4' etched in layer 2 in correspondence with the domains. The light beam is reflected back by layer 1 through holes 4, 4' to a photo-cell via a second polarizer. Since the plane of polarization of the beam is rotated to an extent dependant upon the crosssection of the domain which reflects it the photocell produces a signal proportional to the crosssection of the domain and hence magnetic field H influencing it. The photo-cell signal is fed to a television screen together with a synchronizing signal from the scanner so that a representation of the magnetic field pattern is indicated. Applications. Investigating flux patterns of magnetic heads and visualizing patterns on magnetic tapes and discs, studying magnetic domains, measuring susceptibility variations in inhomogeneous materials, editing video tapes and mapping the field of permanent magnets.

Title: Improvements in carburettors for internal combustion engines
IPC: F02M7/08
Filed: 1940-02-19
Abstract: 537,531. Spray carburetters. VAUXHALL MOTORS. Ltd., TAUB, A., PAYNE, R. F., BURGESS, L. G., and JARVIS, H. H. Feb. 19,1940, No. 3106. [Class 7 (iii)] An economizer valve for admitting emulsifying-air to the fuel at part throttle openings is operated, together with an accelerator pump, by connection to the throttle control lever. Fuel admitted at 2 from the float chamber to a main well 3 is mixed with emulsifying air admitted at the top of a tube 15 and led by a passage 12 to jets 13 in a streamline cross bar 14 in the choke tube, the tube 15 being moved up and down by a cross-piece 21 connected to the spindle 18 of the mixture throttle 19, so as to uncover more or less a number of apertures in the upper end of the tube 15. This tube also carries a spring- mounted valve 22 which closes the air inlet at the top of the well 3 when the throttle is fully open. The cross-piece 21 is also connected to an accelerator pump piston 25, which, when the throttle is suddenly opened, closes the fuelinlet valve 27 and opens an outlet valve 28 leading to a fuel nozzle 26. A storage well 29 prevents this action during ordinary throttle movements. When the well 3 is closed by the valve 22, emulsifying air is drawn from the top of a compensating-well connected to the well 3, and a further well is provided for use in idling. In a simpler form, the valve 22 is used alone, without the tube 15. The air choke valve 38 is operated by an arm 37 connected by a rod 36 to a three-armed lever 33, which contacts with an arm 30 on the throttle 19, so that when the choke is closed the throttle 19 is slightly opened.

The supply of coal-dust fuel to a steam generator 1 is effected by servo-mechanism under the control of bellows 14, 15 subject, respectively, to the pressures in the steam drum and in a steam manifold 3 and having an output member 27 which, through a spring 28, effects the setting of variable-speed fuel feed mechanism through a lever 29, the member 27 being screw-threaded and carrying a nut 36 connected to a feed-back spring 32 and being connected to a friction disc 30 coacting with a continuouslydriven friction-wheel 31 whereby deflection of the nut 36 on either side of a position in which the wheel 30 coincides with the centre of the wheel 31 causes rotation of the wheel 30 to bring about a restoring movement of the nut 36. The bellows 14, 15 act on a lever 13 which is linked to a lever 9 connected to a control-valve 16 of a servo-motor 17, the piston-rod 19 of which acts through a spring 11 on the lever 9 in a restoring sense. The piston-rod 19 is connected also to a spring 20 acting on a lever 21 which, through a rod 33, actuates the control valve 25 for the servomotor 26. A piston 22 in the path of the fluid flow to one end of the servomotor 17 acts through a spring 23 on the lever 21 to increase the deflection of the latter whilst the servomotor 17 is operating. To prevent the friction-wheel 30 from leaving the edge of the wheel 31 in the event of sudden fluctuations stops 35 are provided on the rod 33 whereby a projection 37 on the nut 36 restores the control-valve 25 to the neutral position. A fuel and air controller 4 acting through a cam 6 which may be changed to provide different air/fuel ratios adjusts the position of the fulcrum for the lever 9. The lever 9 is also acted upon by a manuallyadjustable spring 10.

Title: Improvements in gas analysers
IPC: G01N27/16
Filed: 1952-02-08
Abstract: In a gas analyser comprising a heated catalytic analysing element and a similar heated catalytic compensating element arranged in a balanceable electric network, both elements are situated in a housing, the temperature of which is maintained constant, and are exposed to the cooling <PICT:0698456/III/1> action of the gas to be analysed, and means are provided to limit gas flow to the compensating element so that catalytic combustion thereon is substantially prevented.  In estimating combustible constituents, such as carbon monoxide, hydrogen, or methane, the gas is mixed with air, and to estimate oxygen the gas is mixed with hydrogen. Catalytic combustion on the analysing element causes a rise in temperature and a change in electrical resistance which is measured by the electric network.  As shown, air or hydrogen enters at a constant rate through orifice 9 and mixes with the gas entering through a similar orifice; regulating valves as described in U.S. Specification 2,438,973 are used to supply the gases at a constant pressure and constant rate.  The mixture passes through cell 10 and then via line 50 to cell 11. Shield 34 surrounding an analysing platinum filament is provided with a metallic mesh screen through which the gas mixture diffuses, and shield 35 surrounding the compensating platinum filament with a small aperture so as to limit diffusion.  The housing containing the cells 10, 11 is maintained at an elevated temperature by a thermostatically - controlled heater. The filaments are connected through terminals 12, 13, 14, 15 in a Wheatstone bridge network.
