Title: Improvements in and relating to velocity measuring apparatus
IPC: G01P3/49
Filed: 1966-09-07
Abstract: 1,103,644. Measuring speed electrically. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Sept. 7, 1966 [Sept. 10, 1965], No. 39993/66. Heading G1N. The speed of a conductive body, such as the rotary speed of a hollow conductive cylinder 45, Fig. 4, is measured by apparatus consisting of: concentric magnetic members 42, 43 which define an air gap 44 along the circumferential direction of which the magnetic field produced by magnets 46 alternates in polarity, and in which the cylinder 45 rotates; field strength measuring transducers 47, 48 situated at positions where the magnetic field produced by the magnets 46 is the absence of movement of the cylinder 45 is respectively maximum and minimum; and means 51 for measuring the ratio of the outputs of the transducers 47, 48. The field measuring transducers may be Hall plates or transductor probes, and the conductive cylinder may be mounted in the body 43 which then rotates, or a single magnetically and electrically conductive body may replace both the body 43 and the cylinders 45. The magnetic poles 46 may be replaced by D. C. excited coils. Linear speed is measured by an arrangement Fig. 1 (not shown) which is the linear equivalent of Fig. 4, and in which a conductive plate (15) moves in an air gap (12) between two magnetically conductive plates (10, 11) one of which carries magnets or D. C. coils, (13). In a further rotary embodiment, Fig. 2 (not shown), a conductive disc (34) of aluminium rotates with part of its peripheral region between polepieces (32) of an assembly including a permanent magnet (36) and field measuring transducers (37, 38, Fig. 3, not shown). The ratio of the outputs of two Hall plates (S1 S2, Figs. 5 and 6, not shown) measuring the fields produced by eddy currents in the rotating member as it rotates, is derived by supplying to both plates a control current (I) derived from a differential amplifier (52, Fig. 5) supplied with a reference voltage (lo Fig. 5, Fig. 6) and the output of the first Hall plate (S1) The output of the second Hall plate (S2) represents the desired ratio.

Title: A method of operating an oil burner and an oil pressure controlled fuel valve for carrying the method into effect
Inventor: HANSEN GUNNAR LYSHJ
Filed: 1957-12-30
Abstract: 876,774. Supplying fuel to burners. CLAUSEN, M., [trading as DANFOSS VED INGENIOR M. CLAUSEN.]. Dec. 30, 1957, No. 40280/57. Class 75(1). [Also in Group XXIX] A pressure operated control valve 7 in the fuel supply system of a burner (not shown) comprises a piston 9 and a pair of cooperating servo-pistons 19, 20 disposed in the piston 9 and adapted to control a pressure relief passage 18 in such manner that when the fuel pump is started the relief passage 18 is opened for a short time and thereby delays the opening of the control valve 7, and when the pump is stopped the relief passage 18 is again opened and causes a quick closure of the control valve 7. The pump is connected at 14 and the burner at 6. The lower servopiston 19 is a loose fit in a chamber 26 in the valve piston 9 and is urged upwardly by a pressure spring 25. The upper servo-piston 20 slides in the valve piston 9 and is urged downwardly by a weak compression spring 27 but its upward movement is stopped by abutment with a strong coil spring 31. When the fuel pump is started the fuel pressure causes separation of the servo-pistons 19, 20 to open the relief passage 18. Eventually however fuel leaks past the loose fitting servo-piston 19 which therefore moves upwardly to close the relief passage 18. When the pump is stopped the control valve 7 moves downwardly carrying with it both servo-pistons 19, 20 but as soon as the upper servo-piston 20 moves away from the strong coil spring 31 it stops since the weak spring 27 is unable to move it against the residual fuel pressure. The relief passage 18 is thus opened and the fuel pressure therefore drops rapidly. The piston 9 is urged downwardly by a spring 22 which abuts a nut 37 screwed on to a stem 36 on a top closure 33 for the valve casing. Rotation of the closure 33 causes the nut 37 to move along the stem to adjust the spring pressure. At excessively high fuel pressure a sleeve 40 on the piston 9 opens passages 43, 44 to allow fuel to flow through ducts 8 in the piston back to the fuel tank. In a modification the pressure exerted by the weak spring 27 is adjusted by a screw threaded through the closure 33.

Title: Light attenuation means
IPC: H01J9/227
Filed: 1964-10-02
Abstract: 1,048,376. Filters. SYLVANIA ELECTRIC PRODUCTS Inc. Oct. 2, 1964 [Oct. 18, 1963], No. 40322/64. Heading G2J. [Also in Division H1] A lens 43 has a light-attenuating coating 46 which is densest at the centre and diminishes towards the periphery. This is produced by coating the lens with a photosensitive emulsion, and then exposing to an approximately point source of light formed by a pointed rod 37 transmitting the light from a lamp 39, and controlled by a shutter 40. The lens is then processed in conventional manner, to produce a visual negative, which is densest in the centre where the illumination was most intense, and falling off towards peripheral transparency. The other surface of the lens may have an antireflective coating. Thus when used as an attenuator with the same light source, the greater the light intensity the greater the attenuating effect, so producing a more even illumination over the field. The arrangement is used in the manufacture of screens for colour cathode ray tubes. As shown, a glass face panel 19 has a radiation-sensitive coating 17, overlaid with the fluorescent phosphor materials 23. In front of this panel is a foraminous mask 25. Light from source 37 passes through the openings in the mask, and impinges angularly on definite phosphor areas, so that each of the separate colour fields is individually activated, according to the angle of incidence. Instead of being applied to the planar surface of the lens, as shown, the attenuating coating may be applied to the concave surface, or to a thin glass plate positioned between lens and screen.
