Title: Improvements in or relating to oil burners
Inventor: DENNETT GEORGE WILLIAM
IPC: F23D11/10
Filed: 1953-05-13
Abstract: 750,415. Spray burners. WHITE'S MARINE ENGINEERING CO., Ltd. May 13, 1954 [May 13, 1953], No. 13342/53. Class 75(1). An oil burner comprises an oil nozzle c and an air nozzle v both secured to an oil tube o which is axially slidable within a cylindrical air casing a to control the flows of secondary air and oil, the arrangement being such that the air flow between the air and oil nozzles for atomizing the oil remains constant under all loads. The secondary air passes from the air casing a through a variable opening 9 between the air nozzle v and a throat member 8 secured to the casing a and is swirled by vanes z on the outside of the air nozzle v. The atomizing air flows from the air casing a through holes w in the air nozzle v and is discharged around the oil nozzle c ; the atomizing air is swirled by vanes in the space 6 between the air nozzle and the oil tube o or by the holes w being tangential. The oil tube o projects into an oil seal unit k secured within a hollow member e secured to the air casing a. The oil seal unit has two seals f, g on its outer surface between the unit and the hollow member e and two further seals h, i on its inner surface between the unit and the oil tube. Oil is supplied to the space m between the two outer seals f, g through an inlet j in the hollow member e and passes. through holes n into a space q at the rear of the unit k. A tapering V-groove p in the surface of the oil tube communicates with the bore of the tube and co-operates with the rearward inner seal i to form a diverging oil metering orifice through which the oil passes forwardly from the space q. The oil seal unit k can be adjusted axially relative to the cover e to vary the oil/air ratio for all positions of the oil tube and to cut off the oil supply through the V-groove when the oil tube is -in its most forward position. The oil tube is disposed within a tube 7 fixed to the hollow member e and is moved axially by a crank 2 and link mechanism 3 actuated by a hand lever. The oil nozzle c may have radial discharge orifices t as shown; or a single discharge orifice of outwardly diverging annular form. The burner may be fitted into an air register. The Provisional Specification describes a mechanism for moving the oil pipe comprising a shaft having a gear engaging a rack cut into the oil tube. It also describes a device for cleaning a burner having an annular oil discharge orifice, the device comprising a spring-urged plunger which on being depressed operis the discharge orifice.

Abstract: 1,021,736. Centrifugal separators. P. M. VAN DER MEER. April 5, 1963 [April 11, 1962], No. 13579/63. Heading B2P. An apparatus for separating into its components a mixture of a first liquid and a heavier second liquid and/or a heavier solid comprises a generally closed vessel 1 having through its wall 2 a passage 6 provided with an inwardly tapering collar 9 within which is arranged, for the supply of the mixture under pressure, a nozzle 12, Fig. 2 (not shown), having its end face substantially coplanar with the sharp inner edge 10 of the collar and defining therewith an annular passage whose cross-sectional area is equal to that of the nozzle bore 13. The annular passage widens as at 14 and communicates through ports 25 with the interior of a hood 16 provided with a liquid discharge pipe 17 and an air vent 18. A tube 7 mounted in the passage 6 extends downwardly into the vessel which is normally closed at its bottom by a valve 5. Pressure gauges 20, 21 indicate respectively the pressure of the feed and that of the liquid in the vessel. When treating contaminated oil, the vessel and the tube 7 is filled with the oil up to the underside of the collar 9. Further oil is then pumped through the nozzle 12 and issues from the flared end thereof as a jet. It is stated that the jet, on meeting the stationary oil in the vessel, curls upwards and, in doing so, the heavier contaminants are thrown downwardly into the tube 7 by the action of centrifugal force while the purified oil portion of the jet escapes through the annular passage 14 towards the discharge pipe 17. To facilitate the downward flow of the contaminants through the tube towards the bottom of the vessel 1 oil is allowed to escape through a conduit 22 the opening of which is controlled by a valve 23 to create a downward current through the tube 7.
