Abstract: 120,570. Cockaday, L. M. Oct. 27, 1917, [Convention date]. Electric oscillations, producing; spark-gap apparatus. - A spark-discharge system for the production of electric oscillations comprises a source of power periodically connected to the primary winding of a step-up transformer through a rotary commutator, and an oscillation circuit containing a rotary sparkgap. The rotary commutator and spark-gap are geared together and, in the preferred arrangement, a condenser is placed in the oscillation circuit, and the commutator is arranged to open the power circuit during the sparking period. When the power circuit is closed during the sparking period, the condenser in the oscillation circuit is of small capacity or may be dispensed with. In the arrangement shown in Fig. 1, a direct or alternating current source of power E is periodically connected to the primary winding 3 of a step-up transformer IT through a rotary commutator D driven by a motor P and mounted upon a shaft S. The movable electrodes gt of a rotary spark-gap SG are mounted upon the shaft S, while the fixed electrodes g' and g<3> of the spark-gap are connected to the terminals of a condenser Y through the primary winding 18 of an oscillation transformer OT. The secondary winding 26 of the transformer OT is connected in the circuit of an aerial A connected to earth or to a second aerial AA by a switch s. The electrodes gt of the spark-gap SG are displaced relatively to the conducting segments c<2> of the commutator D so that sparking does not occur while the circuit of the transformer winding 3 is completed. In a modification, the electrodes gt and the conducting segments c<2> are so disposed that sparking occurs while the circuit of the transformer winding 3 is completed, and in this arrangement the condenser Y is of small capacity or may be dispensed with. The spark-gap apparatus consists of an insulating disk adjustably mounted upon the shaft S, Figs. 3 and 4, and carrying a conducting ring 40 provided with projecting electrodes gt. The rotating electrodes gt are enclosed in an air-tight casing 36 through which the fixed electrodes g<1>, g<3> project. The commutator D consists of an insulating disk to which the conducting segments c<2> are attached by screws 46, while the fixed contacts c<1>, c<3>, Fig. 6, of the commutator are mounted in insulating sleeves 51 and 52, and are pressed against the segment c<2> by springs 47 and 48.

Title: Improvements in or relating to electric signalling systems
IPC: G08C19/18
Filed: 1930-06-04
Abstract: 356,211. Electric signalling systems. AUTOMATIC TELEPHONE MANUFACTURING CO., Ltd., Strowger Works, Liverpool, RAYNER, T. R., 2, Stretton Avenue, Wallasey, Cheshire, and BURNS, G. A., 4, Lucas Estate, Thomas Lane, Knotty Ash, Liverpool. June 4, 1930, No. 17233. [Class 40 (i).] In means for indicating at a remote point the readings of a meter, the meter needle is adapted to move adjacent to but normally clear of a series of contacts and at intervals to establish electrical connection with one of these contacts, whereupon a signal numerically characteristic of this contact is transmitted to the distant point. In the construction shown in Fig. 1, the indicating scale is provided with a row of contacts 11 corresponding to the indications on the scale, and the pointer 10 of the meter is brought into engagement with one of these contacts by means of a stirrup-shaped member 12 which is connected to armatures of electromagnets 24, 19. The circuits are shown in Fig. 3. The meter controls a rotary step-by-step switch which is set in operation periodically to transmit to the distant point a series of impulses corresponding to the reading of the meter. Relay A has its lower winding connected to a conductor 33 over which impulses are transmitted at regular intervals. On the application of an impulse the winding is energized, a holding circuit is prepared for the upper winding, a circuit is completed for coils SM1, SM2 which operate to bring the meter pointer into engagement with one of the row of contacts on the meter scale, and a circuit is completed through the first bank contact and wiper 3a of the stepping switch, through the relay E, and through the driving magnet PSM. Relay E alone operates in this circuit and completes an energizing circuit for the magnet PSM at the same time shortcircuiting itself. The magnet prepares for the stepping of the rotary switch and operates the interrupter springs psm, opening the circuit of relay E. This relay on releasing de-energizes the magnet PSM which steps the wipers of the rotary switch to the next set of back contacts. Wiper 2a then maintains a locking circuit for relay A, and wiper 3a engages a plate to maintain a circuit for the magnet PSM controlled by the relay E. The wipers of the switch PSS continue to step, and in accordance therewith a line circuit is completed and interrupted for an impulsing relay PR at the distant point. This relay effects the setting of an indicator MCH adapted to indicate the reading of the meter. The impulsing circuit to the distant point is maintained until the wiper 1a engages the contact marked by the engagement of the meter pointer PT with the contact corresponding to the reading of the meter. A circuit is then completed through relay B which locks itself and opens the impulsing circuit. The switch steps round until the home position is reached whereupon relays A, E, B, and coils SM1, SM2 are de-energized. Specification 337,007, [Class 40 (i), Electric signalling systems &c.], is referred to.

Title: Liquid storage tank for use in aircraft
IPC: B64D37/00
Filed: 1957-05-30
Abstract: 836,923. Tanks. WILLIAMS, W. P. (United Aircraft Products Inc.). May 30, 1957, No. 17243/57. Class 69 (1). A liquid storage tank 10 for use in a liquid circulating system of an aircraft includes an open-ended deaerator can 48 mounted within the tank to receive liquid returning from the circulating system and discharged into the tank and to remove any air entrained in the liquid, the deaerator can 48 extending between the normal top and normal bottom of the tank and being of such length that when the tank is in its normal upright position, one end of the deaerator can projects above the normal level 13 of liquid in the tank and, when the tank is inverted, the other end of the can projects above the liquid level. The tank 10 may be filled with oil through a connection 12. An oil return fitting 14 returns the oil from the lubricating and hydraulic systems. A cylindrical member 25 is rotatably mounted on a shaft 22 fixed in an intermediate horizontal plane of the tank 10. The shaft is provided with an enlarged central portion 33 and sealing means are provided to form separate chambers 35, 37. An elongated tube 45 communicates with the chamber 37 and projects into the space above the oil level 13. The chamber 35 communicates with a relatively heavy tube 46 which acts as a pendulum holding the assembly in such a position that the tube 46 extends downwardly towards the bottom of the tank. Tilting motions of the tank corresponding to diving and climbing attitudes of flight of the aircraft result in relative rotary movement between the tank 10 and the pendulum assembly 25, 45, 46 so that the open end of the tube 46 is always submerged in the body of oil in the tank. The chamber 35 also communicates with a tube 41 which delivers oil to the hydraulic system through a fitting 17. The tube 41 is fixed to a stationary boss 26 and does not rotate with the pendulum assembly 25, 45, 46 but will always be fed with oil from the tube 46 whatever the position of the tank. The oil return fitting 14 communicates with a conduit 47 which is directed into the open upper end of the deaerator can 48. The lower end of the can 48 terminates below the shaft 22 of the pendulum assembly. The oil from the conduit 47 is discharged tangentially into the can 48 to release the entrained air. This air rises through the upper end of the can to the space above the oil when it is vented by the tube 45 and a further tube 43 to an air vent 15 (Fig. 1). The tube 43 is fixed to a stationary boss 27 arid does not rotate with the pendulum assembly.

Title: Safety control means for gas heated apparatus
Inventor: NORWOOD HAROLD
IPC: F23N5/10
Filed: 1956-06-05
Abstract: 823,159. Controlling gas burners. SPERRYN & CO. Ltd. June 4, 1957 [June 5, 1956], No. 17300/56. Class 75(1) A safety control device for gas heated apparatus comprises a push button operated pilot valve 10 coupled through a lost motion device to a holding electromagnet 21 energized by a thermocouple 22 heated by a pilot jet 14 and a switch 27 associated with the lost motion device and actuated in one direction by the release of the push button 16 and in the other direction by the deenergization of the holding magnet 21. The switch 27 is used to control a solenoid operated valve for the gas supply to the main burner 33 and may also be used to control fans, conveyers, oven doors. The lost motion device comprises a cage 23 mounted on the upper end of the stem extension 18 of the pilot valve 10 and a bobbin 24 working through a clearance hole in the upper end of the cage 23 and secured to the lower end of a spindle 19 mounted on an armature 20 co-operating with the holding magnet 21. The switch 27 is mounted on the cage and its movable contact arm is connected by a member 26 to the bottom end of the bobbin 24. In the position shown the switch energizes warning devices including a lamp 34. The push button 16 is pushed in to open the pilot valve, and to raise the armature 20 into contact with the electromagnet 21; it may also close a switch (not shown) to energize an igniter. The switch arm flexes slightly in consequence of the small clearance between the cage 23 and the upper flange of the bobbin 24 but does not change its contacts After a time sufficient to heat the thermocouple 22 the push button is released and the cage 23 and pilot valve spindle 18 move downwardly until the cage is arrested by the lower flange of the bobbin 24. This movement actuates the switch'27 to de-energize the lamp 34 and open the electromagnetic valve for the main burner. The movement is insufficient to close the pilot valve 10. If the pilot burner 14 is extinguished the armature is released and the parts return to the positions shown in Fig. 1.
