Title: Fluorescent lamp starting circuits
Inventor: KOBAYASHI TAKIZO
IPC: E05C19/14
Filed: 1958-02-06
Abstract: 853,131. Supply systems for space discharge apparatus. TANAKA, K. Feb. 6, 1958, No. 3889/58. Class 38 (4). A circuit for increasing the light output from a pre-heatable filament fluorescent lamp 6 comprises two identical chokes wound on separate cores each having two equal windings 1a, 1b, 2a, 2b, the windings 1a, 2a and 1b, 2b forming parallel pairs, each pair being connected at one end to a supply terminal X, Y, respectively, and the other ends of each pair being connected across one lamp filament. In operation, as there is no potential gradient across the filament, the whole filament can be worked at the maximum surface electron emissivity thus increasing the light output from a given lamp which is stated to be increased by 50%. A glow switch 5 connected across two of the opposite filament terminals allows the filaments to be heated for starting purposes. A number of other arrangements are described in the Specification having additional and tapped windings on each choke, and one arrangement has a further choke connected across each filament to avoid open circuit conditions giving rise to near resonance voltage multiplication when a series capacitor is employed for power factor improvement.

Abstract: 628,523. Friction clutches. HOBBS TRANSMISSION, Ltd., and HOBBS, H. F. March 4, 1947, No. 4293/48. Divided out of 628,499. [Class 80 (ii)] The subject-matter is the same at that of Specification 628,499, but the claims are directed towards the fact that the centrifugal valve 46 exhausts the clutch-engaging rotary pressure-space 22 at a point 44 at or near its inner diameter so that, when the clutch is automatically disengaged at low speeds by the centrifugal valve, the pressure-space 22 remains filled with liquid the centrifugal force on which provides a residual engaging load, so that when the centrifugal valve 46 closes the exhaust 44 to re-engage the clutch on speed-increase, time-lag, due to the necessity of filling an emptied pressure-space, is avoided. Complete emptying of the pressure-space at any speed can be obtained by the pressure-actuated valve 40 under control of the manual valve 26 as in the above Specification, and serving to empty the pressure-space through an opening 34 near its outer periphery. The Provisional Specification refers to Specification 596,908.

Title: Improvements in or relating to pasteurising apparatus
IPC: A23L3/08
Filed: 1934-02-10
Abstract: 433,150. Rotary conveyers. KUTCHERA, A. J., 6601, Blakemore Street, Philadelphia, U.S.A. Feb. 10, 1934, No. 4490. Convention date, Feb. 11, 1933. [Class 78 (i)] [See also Groups VI and XXXVII] Apparatus for pasteurizing milk, beer, &c. in bottles or other containers having a rotating table 6, 8 for carrying the containers therethrough has a conveyer 24 moving transversely and arranged to receive containers directly from the table. As shown, a casing 2 encloses two annular rotating tables 6, 8 which are supported on rollers 7 carried by studs eccentrically mounted so that by rotary adjustment of the studs the rollers may be raised or lowered to level the tables. Each table is driven by the engagement with a gear 16 thereon of a pinion 18 driven through reduction gear 20 from a motor 22. The discharge conveyer 24 which serves also to feed the bottles to the table, is formed as a chain conveyer extending between sprocket wheels 26, Fig. 5, one of which is driven through reduction gearing 34 from a motor 32. The links of the chain carry supports 30 which taper outwardly and preferably slide over the table. Conveyers 36, 44 with deflectors 38, 46 feed the bottles to and receive them from the conveyer 24. If excessive pressure occurs due to jamming a pivoted bar 48 is engaged by the bottles on supports 30 and is deflected opening a switch 50 causing the stopping of the machine. Electrical control means, Fig. 7, are provided to give the tables 6, 8 an intermittent rotary movement and to vary the speed of the conveyer 24 so as to clear the bottles away rapidly when the table is stationary. The stop switch 50 operated by bar 48 is in series with the starting switch 52. A solenoid 54 is energized on the closing of both switches 50, 52 and closes switches 56, 58. Closing of switch 56 energizes a timing motor 60 which intermittently opens and closes switches 64, 84, the speed of the motor 60 being controlled by a rheostat 62. Closing of switch 64 energizes a solenoid 66 which closes a switch 69 of a starter 70 which starts motor 22 driving the tables 6, 8. A solenoid 68 is also energized and closes a switch 71 which operates the starter 72 for the motor 32 driving conveyer 25. The speed of motor 22 is regulated by a manually adjustable rheostat 76 in series with the field 74 thereof. A vibrating relay 78 is shunted across the rheostat 76. The shunt field 80 of the motor 32 has in series with it a rheostat 82 shunted by the switch 84 controlled by the timing motor 60. When rheostat 82 is short-circuited by closure of switch 84 the motor 32 will drive the conveyer 24 at low speed, the motor 22 then operating to rotate the tables 6, 8, and when the field current is cut down by opening of switch 84 the conveyer will be driven at a higher speed, the tables being then at rest as switch 64 is open. Alternatively, the control may be at least in part mechanical, e.g. by using mutilated pinions in place of pinions 18. U.S.A Specification 1,867,771 is referred to.

Filed: 1926-02-19
Abstract: 271,158. General Electric Co., Ltd., Kinnes, A., and Hunt, M. H. Feb. 19, 1926. Thermal switches, cut-outs, and interrupters.- In a thennostatic device with two sets of contacts controlling the closing and opening of an electromagnetic switch and wherein little or no current flows through the contacts at the moment of opening, the switch is biassed in the open position but on closure of one set of contacts current flows therethrough to an actuating coil to close the switch whilst closure of the second set of contacts short-circuits a switch retaining coil whereupon the switch opens. Adjacent the heating coil 1 of an oven is placed a bimetallic thermostat 2 provided with contacts 3 and 4. A switch 6 is controlled by a retaining coil 5 and an actuating coil 9. On switching on the main current, current flows through the coil 1, coil 5, arm 7, contacts 11 and 4 and actuating coil 9 which results in the closing of switch 6 whereby the main current passes direct through the coupled switch contacts 10-8 and the circuit through the arm 7, contacts 11-4 and coil 9 is shorted. As the coil 1 heats up, the thermostat opens the contacts 11-4 but no sparking occurs. When the temperature reaches a predetermined level, contacts 11, 3 are closed and the coil 5 becomes inoperative so that the switch 6 is opened. Current is now flowing through the contacts 11, 3, so that when the coil 1 and arm 7 cool and the contacts 11, 3 become broken no sparking occurs. In a modification, a single coil is provided for actuating and retaining the switch, a subsidiary resistance being used in the circuit of the contact 4.
