Title: Improvements in or relating to oil burners
Inventor: MENZIE KEITH
IPC: F23D11/08
Filed: 1962-05-18
Abstract: 1,016,182. Rotary oil burners. BIRMING- HAM SMALL ARMS CO. Ltd. May 20, 1963 [May 18, 1962], No. 19186/62. Heading F4T. An oil burner has a rotating spindle 9 which has at its upper end a conical chamber 23 leading to distributer pipes 17 from which oil is flung, and at its lower end a helical groove 20 pumping oil upwards from an oil inlet 19 in a bearing sleeve 8. From the helical groove 20 the oil passes upwards around a reduced cylindrical portion of the spindle and via a transverse bore 21 into an axial passage 22 leading to the chamber 23. The spindle 9 is located in the sleeve by upper and lower bearing surfaces 10, 11 and a ball 12 taking axial thrust. Secured to the top of the spindle 9 is a cup-like member 13 enclosing the upper end of the sleeve and carrying a rotating armature 15 of an electric motor 16. The pipes 17 extend from the member 13 and terminate adjacent fan blades 18. Oil is prevented from leaking between the spindle and sleeve to the motor by a downwardly pumping scroll 25 adjacent bearing surface 10. The sleeve 8 is housed in a bush 7 in a base 6 of the burner casing 5. The burner is connected to an oil supply tank by a pipe having a solenoid operated shut-off valve and the level of oil in the tank is constant and below the upper end of the bearing sleeve 8, thus preventing fuel spillage when the spindle is stationary or when the valve fails to operate.

Title: Improvements in and relating to the manufacture of sintered powder metal materials
IPC: H01H1/0233
Filed: 1960-05-31
Abstract: 881,204. Moulding metal powders. MALLORY METALLURGICAL PRODUCTS Ltd. May 31, 1960 [June 26, 1959], No. 19216/60. Class 87(2). [Also in Group II] A sintered metallic body, such as an electrical contact, with different properties along one face is formed by filling a die with metal powder to different depths of fill and compacting the powder to a greater extent in the regions of greater depth than in the regions of lesser depth and then sintering the compact to form a body with progressively different densities in a direction transverse to the compression. The powder such as W, Mo, Ti, Ta, Nb or Zr or carbides of these metals of 5-7 micron size is charged into a die 14, the bottom punch 12 and the top punch 15 having parallel inclined faces 13 and 16. Compression at 20,000-30,000 p.s.i. is effected by the movable top punch to form a compact which is more highly compacted on the left hand side than on the right. In Fig. 3, the centre of the compact is more highly compacted than the periphery. Sintering is effected in a reducing or protective atmosphere or in vacuum at 1200C. and the compact is then impregnated with Cu, Ag and/or Au, and/or Pt group metals and/or alloys of these metals. Additives such as Si, Cd, Zn, Sn, Pb, In, Ca, As, P or Sb, may also be present.

Filed: 1955-07-02
Abstract: 823,930. Etching. BIRMETALS Ltd. June 29, 1956 [July 2, 1955], No. 19217/55. Class 100(2) In an etching machine, traversing gear comprises a rotary drive and means for resolving the rotary movement of the drive in two mutually transverse directions to give a pair of oscillatory drives out of phase with one another, these oscillatory drives being coupled to a carrier for the plate to be etched in such a manner that one causes rotary oscillation of the carrier about an axis of the carrier and the other causes reciprocation of the carrier along a predetermined-path transverse to this axis. A carrier 38, Fig. 1 for plates to be etched by solution splashed by paddles or sprayed thereon from below, is mounted on shaft 36, part of which is formed as a coarse-threaded two-start screw 27 rotatably mounted in a carriage 31 slidable by means of convex-faced rollers 33, Figs. 1 and 2, on rails 32. Vertically slidable on rods 23. 23' secured to the carriage is a slider 22 in which is rotatably mounted a nut 24 engaging the screw and integral with a worm wheel 25 engaged by a two-start worm 21. The worm 21 is rigid on pin 20 rotatably mounted in the slider and rigid on a crank disc 18 rotated at three revolutions per minute by a member 16 connected by overload shear pins 15 to a sleeve 14 fixed to the output shaft 13 of a speed-reducer 12 driven from an electric motor 11. The circular orbit of the pin 20 and worm 21 causes the slider 22 and nut 24 to be reciprocated vertically, thus oscillating.the screw 27 and carrier 38, and the carriage 31 to be reciprocated horizontally in a slot 37 in a base plate 10, thus reciprocating the carrier. A baffle plate 49 is slidable with the carrier. By withdrawing a plunger 44 manually, the carrier 38 can be disconnected from the shaft 36 and independently rotated during the fixing of a plate thereon. As the pin 20 moves round its orbit the worm 21 rotates the screw 27 so as to progress angularly the oscillation path of the carrier. The screw may drive the shaft 36 through bevel gears instead of being integral therewith, in which case the screw is horizontal and the shaft 13 vertical. One element of each of the bearing, meshing and rolling pairs is made of a self-lubricating superpolyamide resin, such as nylon.

Abstract: 1512995 Two-stage compression of particulate material MITSUISHI FUKAI TEKKOSHO LTD 7 May 1975 [9 May 1974] 19220/75 Heading B5A Particulate material is compressed in a first stage in a mould to form an intermediate brick, which is then compressed further in a second stage in a mould after entrapped air has escaped from the material, this mould having a cross-sectional area perpendicular to the direction of compression that is greater than that of the intermediate brick. A single mould of variable cross-sectional area can be used for the two stages of compression, or as described the brick is transferred to a second mould. In Fig. 1, a charger 4 transfers a supply of particulate material from a hopper 3 to a first mould 8 wherein it is compressed by an upper plunger 12. The mould 8 and charger 4 are then lowered by cylinders 11, and a pusher 5 moves the intermediate brick 28 onto a table 26, where entrapped air escapes. A shifter 15 then moves the brick 28 on the lower abutment 23 of a second press, the second mould 19 is raised to the position shown in Fig. 1 with spacing left all or partially around the brick, and an upper plunger 22 compresses the brick. The second mould 19 and shifter 15 are lowered by cylinders 21, the brick engaged and raised by a holder 16 and cylinder 17, and then placed on a conveyor 30 for removal or further compression stages. A succession of pairs of bricks are compressed in side-by-side mould cavities and transferred simultaneously; Fig. 6 illustrates the transfer stage.

Filed: 1943-11-23
Abstract: 569,515. Clutches. SINCLAIR, H. Nov. 23, 1943, No. 19583. [Class 80 (ii)] [Also in Group XXIX] A clutch employing a working liquid which may force friction elements into engagement by its centrifugally generated pressure, or .may have vaned impeller and runner elements co-operating to form a circuit, comprises a working chamber (formed as shown by the impeller 13, and runner 21 and an outer shell 20), a rotary reservoir 38 and a scoop 50 transmitting liquid from the reservoir to the working- chamber and a supplementary reservoir 69 in the rotary parts receiving liquid not required by the working chamber and releasing it slowly to the reservoir. The shell 20 and auxiliary reservoir shell 23 are welded together and end in a flange 24 which with a ring 39 on the reservoir shell 18 is bolted to the impeller. ' The ring contains a centrifugal valve which at low speeds is open to deliver liquid from the working chamber to the reservoir and has also a leak port always open to discharge excess hot liquid. The scoops deliver through ports controlled by sleeve valve actuated by a control lever 58, to the space between runner 21 and shell 20, and excess liquid passes through the clearance between shell 20 and a stationary housing 44 into the auxiliary reservoir space 69; the housing is formed with a filling duct 66 and surrounds the runner shaft 27 coupled e.g. to a gear-box by a flexible coupling. The shaft carries thrower rings 59, and the valve actuating sleeve, housing 44 and scoop ring 45 have drain ports to prevent leakage. A gland drum 48 is fixed to the ring, co-operating with discs 43, 49 on a gland tube 42 forming an inner wall of the reservoir. - The rear end of the reservoir is re-entrant, enclosing a bell housing 64 which accommodates a flexible mechanical coupling 29. Fig. 3 shows the coupling in conjunction with a vehicle engine 81 and a mechanical change-speed gear 82, e.g. as described in Specification 376,468, having gear-selecting clutches biassed towards engagement by a preselector 84. A friction clutch 83 may couple the input gear shaft, connected to the runner, with an output shaft 85 in a high-speed ratio during gear changes. The gear-selecting clutches may be as described in Specification 486,589. The clutch 83 and the valve lever 58 are actuated together by a pedal 88, lost motion allowing the valve to be closed without engaging the clutch. In a coupling for use with A.C. electric motors as an automatic starting clutch, the sleeve valve may be replaced by a pop valve opening automatically at a given speed, and the centrifugal emptying valves may be omitted.

Filed: 1936-07-21
Abstract: 478,653. Television. ZEITLINE, V., ZEITLINE, A., and KLIATCHKO, V. July 21, 1936, No. 20186. [Classes 39 (i) and 40 (iii)] The frequencies m, m + n of two preferably perpendicular fields, which deflect a cathoderay, differ by a small amount n of the order of the number of pictures per second. Controlling frequencies are generated by interrupting light incident on auxiliary cells by two sets of slots, differing in number by one unit, in a rotating disc, or by relaxation oscillators with a small difference in the charging or discharging times, or by commutators. These synchronizing frequencies are applied to two amplifying valves 18, 19 in parallel with a third 16 which supplies picture signals to a common anode resistance 26. In the resulting mixture, one set of synchronizing signals is more positive than the picture signals and the other set is more negative, Fig. 3 (not shown). At the receiver, Fig. 5 (not shown), the synchronizing signals are filtered out by amplitude or frequency selection or both. The individual signals of the two sets may differ in amplitude, or duration, or they may be composed of oscillations of different frequency. When two of the signals would coincide, one is displaced a small amount. The difference n between the frequencies may be a multiple or sub-multiple of the image-changing frequency, or it may be varied for secrecy. The periodicity and the amplitude of the synchronizing signals may be varied cyclically' to . give a circular scanning field, Figs. 8 and 9 (not shown). The synchronizing signals may be generated and the ray returned by auxiliary electrodes, of different length and conforming to the edges of the picture, beside the fluorescent screen 12 of the cathode-ray tube 9, Figs. 10-12 (not shown). When using velocity modulation, two condensers are charged by the signals through two valves or one double-anode valve, and are discharged by the synchronizing signals, which are separated by a push-pull filter, Figs. 6 and 7 (not shown).
