Title: Improvements in and relating to gaseous fuel burners
IPC: F23C7/00
Filed: 1966-06-09
Abstract: 1,137,985. Burners. BABCOCK & WILCOX CO. 9 June, 1966 [9 June, 1965], No. 25792/66. Heading F4T. A gaseous fuel burner 10 for a steam generator and firing through a circular port 11 in a water-cooled chamber wall 12 has a front wall 14 spaced from wall 12 to form a windbox 15 to which superatmospheric air is supplied, the walls of port 11 connecting with the annular front plate 22 of a cylindrical air register 20 supported coaxially in windbox 15. The register 20 includes blades or vanes 23 pivotally mounted to be rotatable about their axes which are parallel to the central axis of port 11. A fixed tubular sleeve 30 axially arranged with respect to port 11 terminates within the register and has slidably mounted within it a tubular distance-piece 31 carrying a vaned impeller or diffuser cone 32 which disrupts the airflow stream so as to form a shielded turbulent air zone on its downstream side. An oil atomizer assembly 50 is housed within the tube 30 so that the atomizer tip 51 terminates adjacent impeller 32. Disposed within windbox 15 is a torusshaped gaseous fuel manifold 40 connected to spud elements 42 having chisel-faced tips and a sighting tube 18 provides means for visual monitoring. Each spud element 42 has a collar or shielding plate 45 which produces a shielded turbulent air zone on the downstream side thereof. As the gas burner load is decreased smaller proportions of fuel are projected into the zone downstream of impeller 32 and the primary location of ignition stability is transferred to the spud collar zones. When firing gas alone, the impeller 32 is positioned slightly upstream of the spud collars but when firing oil and gas in combination the impeller is heated downstream of the spud tips. The oil burner may be replaced by a further gas spud or a pulverized solid fuel burner.
Patent GB-962762-A (GB)
Title: Liquid dispensing means comprising a non-drip spout for a container
IPC: B65D47/28
Filed: 1961-07-17
Abstract: 962,762. Container closures. K. NAGAI. July 17, 1961, No. 25821/61. Heading B8T. A screw-cap for a container 1 comprises a non-drip spout housed in a passage 5 in the cap and actuated manually by a plunger 15, 16 having valve members 13 and 14. As the plunger is pushed forward, a spring 17 carried in a stationary cylinder 9 is compressed, Fig. 2, and the valve member 13 uncovers an air vent 18. A sleeve valve 10 slides in the passage 5 when the valve member 14 pushes forward a pin 20 carried by the sleeve and moving in a groove 6. An aperture 19 in the sleeve is aligned with an outlet 8 to permit liquid to be poured out when the container 1 is tipped. On release of the plunger, the member 14, acting on an air cushion trapped at A in the sleeve valve 10, causes the sleeve to retract thereby closing the outlet 8. Air trapped at B behind the sleeve valve 10 temporarily slows the movement of the sleeve and causes the member 14 to slide in the sleeve thereby forming a vacuum in the sleeve to draw back drips from the spout and return them to the container as the aperture 19 becomes aligned with a drain hole 8<SP>1</SP>. The member 14 then acts directly on the end of the sleeve 10 to overcome the air cushion at B and fully retract the sleeve. Escaping air passes down the groove 6 under control of a set-screw 21.

Abstract: 839,895. Polarizing apparatus; microscopes. ABBEY, A. (American Optical Co.). Aug. 16, 1957, No. 26008/57. Class 97(1) In a polarizing apparatus comprising a polarizer and analyzer rotation of the plane of the polarization due to the oblique incidence of plane polarized light on refracting e 1 e - ments is compensated by a phasealtering plate and a "rotary compensator." The latter may be formed by refracting e 1 e - ments normally used and disposed between the phaseshifter and the analyzer or by a meniscus air or glass lens of zero power. In the microscope of Fig. 1, reflected light from mirror 16 is plane polarized at 12 and formed by condenser 18 at 24. Lenses 42 formed on plane 24 transmit parallel light through a half-wave plate 50 to lenses 44 which form the light on an object at 36 an image of which is formed by objective 26 behind a crossed analyzer 30. The plane of polarization of the light emerging from polarizer 12 is rotated due to oblique incidence of some of the light rays in lenses 18 and 42, is reversed by the halfwave plate 50 and additionally rotated by oblique incidence on lenses 44, 26 so that plane polarized light is incident on the analyzer 30. The half-wave plate 50 may be provided by a rhomb giving four internal reflections, at each of which there is a #/8 phase change. In a modified microscope, a unit comprising a half-.wave plate and a rotary compensator formed by a meniscus air or glass lens of zero power may be disposed in the light path between polarizer and condenser and between objective and analyzer; each unit may be axially adjustable. As shown in Fig. 10, such a unit may consist of a half-wave plate 133 and two meniscus air lenses 132A and 132B of which the latter is axially adjustable. Lens 132A and lens 132B together with the half-wave plate may both be adjustably mounted in a tube.

IPC: C08F28/00
Filed: 1953-09-28
Abstract: Acrylonitrile is copolymerized with an aryl sulphonic ester of an unsaturated alcohol having the general formula CH2 = C(R)-R1-O-SO2-R2 in which R is hydrogen or methyl, R1 is a divalent hydrocarbon group, and R2 is an aryl group, e.g. allyl and methallyl para-toluene sulphonates, the proportions of the monomers being such that the copolymer contains at least 85 mol. per cent of acrylonitrile and 0.5 to 10 mol. per cent of ester, by forming an aqueous emulsion of the ester with less than the total amount of acrylonitrile and other monomers in the presence of an emulsifying agent and a protective colloid, adding gradually at a predetermined rate the remaining acrylonitrile, mixed with other monomers, if any, at the end of polymerization breaking the emulsion with water, and then reacting the copolymer obtained with ammonia or a primary, secondary, or tertiary amine.  The copolymerization is described of acrylonitrile, allyl para-toluene sulphonate, and methyl acrylate in an aqueous emulsion containing polyvinyl alcohol as a protective colloid, the sodium salt of a sulphonated long chain alcohol as an emulsifier, and a mixture of ammonium persulphate and sodium bisulphite as a catalyst.  Another emulsifier specified is the dioctyl (2-ethylhexyl) ester of the sodium salt of sulphosuccinic acid.

Abstract: 503,477. Model race tracks. CLARK, A. T. Oct. 1, 1937, No. 26582. [Class 27] [Also in Group XV] A :model track for electrically operated miniature cars or other vehicles comprises a circuit having two, three or more paths, means for electrically energizing the vehicles from the paths and means for guiding the vehicles thereon, said paths having interconnecting or transfer paths, which are so arranged that a car can transfer from one path to another and means operated by the vehicles on the paths for preventing a transference if the portions of the paths are so occupied that a collision would result. Sections of the track are arranged when occupied by cars to vary the voltage on other sections. The track is mounted on a wooden base made in two sections, joined by a plate 3, and lit by a lamp 5. The path is made up of four parallel copper strips Ca, Cb, Cc, Cd, the cars A, 13, C, D having current collectors S, Fig. 2, to connect with the appropriate strip, and pins 9 to engage in guide slots 7, but at converging CV and diverging DV parts of the track, the copper strips are joined as shown under the car D, Fig. 2. The points 11 at Dv and DV<1> are controlled by electromagnets 12 so that as long as a car is running on a " Point Control " section with its appropriate power button AP, BP, CP, or DP depressed by a competitor, the point is set for cars to take the outer path, otherwise the car takes the inner path. The " Convergence Control " section prevents two cars meeting at CV by cutting the current off from one of the approach paths through a relay Rc, Fig. 1. A car receives higher voltage current if on a " Boosted Section while another car is on a " Boost Control section through a relay Rb, the latter car suffering a reduction in current. The arrangement of the track sections is set out in Fig. 3, differentiated to show common sections CO, convergence control CC, boosted sections BS, boost control BC, and point control PC. The apparatus may be controlled by coinfreed mechanism or may be used for advertising or display purposes.
