Title: Improvements in spray carburettors
IPC: F02M9/00
Filed: 1929-06-24
Abstract: 337,000. Kirsch, J. B. June 24, 1929. No Patent granted (Sealing fee not paid). Spray carburettors -A fuel nozzle is adjustable relatively to a fixed needle valve to vary the fuel supply, is connected through a lost-m, tion device to an air valve and, in being moved to increase the fuel outlet, restricts the air passage at the throat of the mixing chamber in which it is mounted. The fuel pipe 1, Fig. 1, carries a socket 5 having a coarse pitch thread 7 with which engages a thread on the nozzle 9. The nozzle outlet cooperates with the tapered end of a needle valve 13 which is normally fixed, but may be adjusted and then locked by a cap 15. A plate 3a with sector-shaped apertures 22, Fig. 2, is secured by a boss 21 screwing into the socket 5, and over this plate is a disc 23 with apertures 24 to control the air supply. The nozzle is adapted to be rotated by an arm 25 an elongated slot 32 in which engages a pin 31 in the disc 23. The mixing chamber 4 is secured by its flange 33 to a rim 28 of the plate 3<a>. A plate 30 covers the slot provided for the arm 25. A valve 16 in the fuel conduit is carried by a piston 18 loaded by a spring 19 and adapted to be acted upon by suction through a pipe 20. By virtue of the pin 31 and slot 32 a rich mixture for accelerating may be obtained. When the engine stops, the fuel supply is cut off by the valve 16 and leakage and risk of fire prevented. The valve 13 facilitates clearing of the nozzle orifice. In a modified construction, Fig. 4, the plate 3, with apertures 22 is formed in one with the fuel supply portion 1, and the mixing chamber is in the form of a Venturi tube and connected to the plate 3 by screws 35. The nozzle comprises an outer part 36, 37 adapted to be moved axially over an inner part 38. The part 38 has on its outer surface a steep pitch helical groove 40 with which a pin 41 on the part 36 engages. A hub 44 is adapted to be rotated by an arm 25 and carries pins 43 adapted to enter bores in the part 36. Rotation of the hub therefore produces axial movement of the part 36 and the fuel supply is varied. The aircontrol disc 23, with apertures 24, carries pins 46 adapted to be engaged with lost-motion by the arm 25. The slot through which the arm passes is covered by a ring 45 rigid with said arm. The nozzle orifice may be completely closed by the needle in which case the latter may be bored as at 47, Fig. 7, to provide a duct for idle running.

Abstract: 147,564. Siemens & Halske Akt.-Ges. Sept. 18, 1918, [Convention date]. Inductive signalling.-In systems for indicating fairways by submarine cables carrying alternating current, port and starboard receiving-coils b, a on the ship are alternately connected to a telephone or galvanometer J by an automatic switch, to enable the indications of the two coils to be compared. In the arrangement shown in Fig. 2, the automatic switch consists of two slow-release relays R1, R2. When the switch 7 is closed, the relays R1, R2 are energized alternately for intervals determined by their period of release, the relay R1 energizing the relay R2, which then short-circuits the relay R1, and so on. Indicators la, lb show which coil is in circuit. In a modified arrangement, the coils b, a are put in circuit alternately by a rotary switch. There may be a single cable in the middle of the fairway, or one on each side.

Title: Improvements in or relating to electrical plug and socket connecting devices
IPC: H01R13/502
Filed: 1951-08-20
Abstract: 701,408. Two-part couplings. MODREY, H. J. Aug. 20, 1951, No. 19570/51. Class 38 (1) A plug, Fig. 1, comprises a flexible rubber shell 55 carrying at 58 an inner metal shell 56 connected to a conductor 57 and to the inner end of a clamping rod 59 having a clamp head 60. The rod 59 is slidable in a cup 63 which telescopes over the shell 56, and a locking slide 61 slidable on the rod 59 has a flange 66 engaged by a spring 65. The socket comprises a rubber shell 45 housing a cup 47 provided with a hole 50 and connected to a conductor 48. The size of the hole 50 corresponds with that of the clamp head 60 so that on presentation of the plug to the socket the slide 61 is retracted relatively to the head 60. When the head has passed through the hole 50 the locking slide 61 is moved into the hole by the spring 65 thereby locking the plug and socket together. On engagement of the plug in the socket the cup 63 abuts a wall 49 of the cup 47 and is telescoped further over the shell 56 ; also the forward end of the shell 55 is forced over the taper 52 of the socket shell 45 to form a seal, the shell 55 being both axially shortened and transversely expanded. To release the plug the shell 55 is gripped at its rear end and pushed towards the socket whereby the shell is further shortened and its rear end moves relatively to the cup 63. Lateral pressure is then applied so that a ridge 64 on the cup 63 is gripped by the shell 55 to hold these two parts in their relatively-displaced positions in which the head 60 extends beyond the slide 61 to permit the plug removal. In Fig. 4, the plug contact comprises a metal tube 74 secured to a rubber shell 75 at 76, and adapted to be inserted in a socket plate 71. The tube 74 has a pair of slots 81, 83 through which noses 80, 82 of a wire spring 79 respectively extend On insertion of the tube 74 into the socket hole 73 nose 80 is forced back into the tube and thereafter snaps out to lock the plug to the socket, the shell 75 being axially compressed and transversely expanded to make a seal with the socket member 70. The plug is released by pressing a button 84 to engage the nose 82 and move the spring 79 to the dotted-line position. In a further construction, Fig. 5, a rectangular section contact 94 secured at its inner end to a rubber shell 95 rotatably carries a sleeve 97 having a bayonet slot 98, a torsion spring 101 being connected between the sleeve 97 and the contact 94. The socket contact 91 carries a pin 100 which enters the slot 98 and rotates the sleeve 97 against the tension of spring 101 when the plug and socket are engaged, the pin 100 finally entering a locking groove 99, and the shell 95 being forced over a tapered part 90<SP>1</SP> of the rubber socket shell 90 to form a seal. To release the plug the shell 95 is compressed against the knurled portion of the sleeve 97 which is then manipulated by pushing on shell 95 to free the pin 100 from the groove 99, whereupon the spring 101 rotates the sleeve 97 to assist in the plug separation.

Title: Production of titanium dioxide
Inventor: EVANS ARTHUR WALLACE
IPC: C01G23/047
Filed: 1964-05-13
Abstract: Finely divided titanium dioxide is obtained by vaporizing solid material containing titanium dioxide by contacting it with a substantially inert gas heated to a temperature above the boiling point of titanium dioxide and condensing the vaporized material.  The heated gas may be in the form of a plasma and may be e.g. argon, oxygen or free-oxygen containing gas such as air, nitrogen, helium, neon, krypton, carbon dioxide or oxides of nitrogen.  a minor proportion of a gas which has a high thermal conductivity, e.g. hydrogen, may be included.  The heating may be in the form of an arc between electrodes preferably arranged as a central electrode and an annular electrode both of which may be cooled by means of a circulating liquid coolant. The current may be direct or alternating. Induction heating may be employed by passing the gas through a space surrounded by a confining tube of e.g. silica and around which is wound electrically conducting material, e.g. copper tubing carrying an alternating current of, say, 200 kilocycles to 10 megacycles.  A gaseous or liquid coolant, e.g. water, may be passed through the coil.  The gas may be in helical or laminar flow or a mixture of both.  The first and last turns of the coil may be in a direction opposite to that of the remainder. The particles of titaniferous material may be of 30-100 microns and may be added to the gas stream as described in Specification 1,093,442.  The condensed material may be subjected to a magnetic or electric field.  A rutilizing agent, e.g. an aluminium halide or zirconium tetrachloride may be added before vaporization and other <PICT:1093441/C1/1> modifying agents, e.g. compounds of silicon or boron such as the halides, or lower halides of titanium, water or alkali metal ions may be added before or after vaporization.  An apparatus as shown comprises two silica tubes (1) and (2), around (1) are wound coils of copper tubing (3) connected to a radio-frequency generator. A silica tube (4) provides an annular space (5) through which gas may be passed.  Silica tube 6 with orifice (7) is attached to a supply of particulate material and feed gas.  The lower end of (2) is connected through a filter to a source of reduced pressure. Tube (2) is cooled with air through pipes 8.

Abstract: 1,047,908. Electro erosion. BETElLIGUNGS - UND PATENT VERWALTUNGS G.m.b.H. May 12, 1965 [May 13, 1964], No. 20112/65. Heading B3V. [Also in Division G3] In an electro-erosion machine having a plurality of spark gaps each associated with a separate working circuit including a discharge capacitor 1, a tool electrode 4 and a workpiece 2, the spark-gap voltage UF is applied by way of a resistor 5 to the plates 6A, 6B of a capacitor 6; an auxiliary voltage UK derived from a source 9 and a potentiometer 8 is applied to the plates 6A, 6B by way of a resistor 7, the voltages UF and UK being in opposition. The voltage UK determines the desired size of its associated spark gap, and any differences between UF and UK appear as positive or negative difference voltages at the points A and B which are con - nected to a control section (Fig. 2, not shown) for the single feed drive which regulates the sizes of all the spark gaps and which may comprise an electric motor or an hydraulic device. The control section may include thyratrons, transistors or relays, and is arranged so that it delivers directional regulating signals to the feed drive depending on the highest negative or positive difference voltage present; the arrangement is also such that the presence of a negative difference voltage renders positive difference voltage ineffective, so that regulating signals arising from too short a spark gap have priority.
