Title: Improvements in the manufacture of chlorine dioxide
IPC: C01B11/02
Filed: 1950-01-31
Abstract: In the manufacture of chlorine dioxide by reacting alkali or alkaline earth metal chlorates with aqueous mineral acid solution, less acid than the stoichiometrical proportion corresponding to the chlorate is used, the remaining excess chlorate being supplemented by further chlorate and then subjected again to the acid treatment.  The residue solution remaining after the reaction may be partially evaporated and the <PICT:0672047/III/1> solution subjected to a chlorate electrolysis to convert the chloride formed in the reaction to chlorate.  Alternatively the chloride may be removed from the evaporated residue solution by crystallization and fresh chlorate added.  In the drawing, a chlorate solution from a container 1 is fed to a series of reaction vessels 2-7 and reacted with hydrochloric acid from container 8.  A current of air is drawn through pipe 9 through the vessels 7 to 2 and out at pipe 14 together with the chlorine dioxide and chlorine produced.  The reaction solution is passed from collection vessel 11 to an evaporator 12 and thence dependent on whether the chloride is wholly removed or not to a vessel 15 where fresh chlorate and water is added, or to an electrolysis vessel 19.  The solution is recycled via pipes 17 or 21 respectively to the container 1.

Title: Improvements in or relating to electric clocks
IPC: G04C1/06
Filed: 1933-01-30
Abstract: 414,372. Oscillating motors. LOEFFLER, F., 46, West 40th Street, New York, U.S.A. Jan. 30, 1933, No. 2862. [A Specification was laid open to inspection under Sect. 91 of the Acts, July 31, 1933.] [Class 35.] An electric motor for self-winding clocks, comprises a body 1, Fig. 1, of insulating material having embedded in it a series of U-shaped magnets 3 energized by a coil 6. A rock shaft 9 is mounted coaxially with the coil 6 and carries a series of sector-shaped bars 8 which are biassed in one direction against a stop by springs 45, 46 and are moved in the opposite direction when the magnets are energized. The shaft 9 carries at its upper end a cam 44 which opens a spring contact in the circuit of the coil, and allows the oscillating bars 8 to return under the action of the springs 45, 46. Fig. 3 shows the device for opening and closing the circuit. The shaft 9, which carries the cam 44, also has an arm 52 to one end of which is pivoted at 50 a hook-shaped member 53. One spring 45 is attached to this member near its pivot and the other spring 46 is attached to the shaft 9 by a stud 51 which passes through a slot in the member 53. The spring contact arm 42 has an end downturned and bearing on the cam 44. This end moves along the flat part of the hook until it snaps under the curved underside and so produces a quick opening of the circuit. On the reverse movement of the shaft 9, the parts reset themselves as shown. According to a modification the motor may comprise pairs of magnets excited alternately to produce a step-by-step rotary movement on the armature. The Specification as open to inspection under Sect. 91 comprises also an alternative form of motor in which the magnets are arranged about the periphery of a cylinder and the rotor consists of bars connecting two discs enclosing the magnets. This subject-matter does not appear in the Specification as accepted.

Title: Thermally actuated electric flashers
IPC: H01H61/06
Filed: 1957-01-25
Abstract: 809,391. Thermal switches; electromagnetic relays. SIGNAL-STAT CORPORATION. Jan. 25, 1957 [June 6, 1956], No. 2869/57. Class 38 (5). [Also in Group XXXVIII] The snap-action switch of Specification 769,505 is modified by mounting the vane 10 on a magnetic core 20, the contact 18 carried by the vane co-operating with a fixed contact 27 insulatingly carried by a part 23 of the core. The contact 27 is connected to one end of a winding 25 on the core, the other end of said winding being connected to a terminal 31. The latter is adapted to be connected to the battery 55 and is connected to a heater 45 wound on and connected to a " hot-wire " 40 attached at its ends to the vane 10. The core 20 is connected to a terminal 32 adapted to be connected to a selector switch 50 for vehicle indicator lamps SL, SL<SP>1</SP>. When switch 50 is closed one way or the other, a circuit is completed through the core 20, the vane 10, wire 40, heater 45, terminal 31 and the battery. The wire 40 then expands and allows the vane 10 to snap over to close contacts 18, 27. This completes a circuit through core 20, vane 10, contacts 18, 27, winding 25 and terminal 31. The heater 45 is thereby shorted so that the wire 40 begins to cool and the lamps SL, SL<SP>1</SP> are lit; also the winding 25 is energized to attract an armature 35 carried by a spring 37 so as to close contacts 38, 33<SP>1</SP> in the circuit of a pilot lamp PL. When the wire 40 has cooled, contacts 18, 27 re-open and heater 45 is again effective, the attraction exerted on the vane 10 by the winding 25 assisting the snap opening. Specifications 765,755 and 769,506 also are referred to.
