Title: Lamp starting circuits
IPC: H05B41/04
Filed: 1980-09-19
Abstract: A lamp starting circuit for a high or low pressure sodium lamp has a thyristor Th1 connected in series in a resonant circuit including a capacitor C1 and a primary winding L1 of a transformer arranged to supply high voltage pulses generated by switching of the thyristor Th1 to a lamp. To prevent this part of the circuit from continuing to operate if the lamp fails to ignite after a suitable time during which the high voltage pulses are supplied to it, the thyristor Th1 is connected to a timer circuit which holds the thyristor Th1 off after a predetermined time starting at switching on of the starting circuit. The timer circuit includes a capacitor C3 arranged to be charged to a breakdown voltage of a zener diode Z2 unless the lamp strikes before this voltage is reached. When the zener diode Z2 breaks down, it passes current to a switching transistor Tr1 which when conducting switches off the thyristor Th1 until the supply is disconnected. <IMAGE>

Patent GB-804243-A (GB)
Abstract: 804,243. Clocks. WENDER, E. J. Feb. 13, 1956 [Nov. 13, 1954], No. 14106/54. Class 139 [Also in Groups XIX, XXXVII and XXXVIII] A timing device comprises a dial 14, Fig. 3, fixed to a sleeve 15, 15a rotatable in a hole in a frame plate 11. A shaft 18 passes through the sleeve 15, 15a and carries a pointer 19. A clutch member 20 is fixed to the shaft 18 and co-operates, as described later, with a complementary clutch member 26 continuously rotated by a constant speed motor 28. Fixed to the shaft 18 is an arm 21, Fig. 4, and a heart-shaped cam 23. Fixed tc the sleeve 15, 15a is an arm 16 to which is pivoted an arm 25 carrying a roller 24 which is spring urged towards the cam 23. The dial 14 may be rotated by rotation of a knob 17, Fig. 3, to bring a desired graduation opposite a fixed index mark (not shown). During this setting movement of the dial 14 the pointer 19 moves therewith by the engagement of the roller 24 and cam 23. Upon manual depression of a plunger 31 against the pressure of a spring, a lever 29 is rocked about its pivot 30 to move the clutch member 26 into engagement with the clutch member 20. The plunger 31 passes through a hole in a lever 22 which locks the plunger in its operative position in which the lever 29 depresses a push button 36 to close a control switch 35. The motor 28 rotates the pointer 19 through the clutch 20, 26 until the arm 21 moves the lever 22 to release the plunger 31 which is returned to its initial position. The pointer 19 is immediately returned to its initial position relative to the dial 14 by the action of the roller 24 on the cam 23. The plunger 31 passes through a knob 33 clockwise movement of which effects depression of the plunger 31 to an extent sufficient to engage the clutch 20, 26 but the lever 22 does not move into the path of the arm 21. The pointer is then rotated continuously. The knob 33 has a pin 33a which upon counter-clockwise movement of the knob 33 moves the lever 22 to free the plunger 31 and effect disengagement of the clutch 20, 26. The dial 14 has associated therewith a light guide 3, Fig. 1, which extends radially of the dial and has at its outer end a bulb 1. The light from the bulb 1 passes along the guide 3 to a prism system 7, Fig. 2, at the centre of the dial and is radiated to illuminate the area 8 of the dial the calibration marks of which may be transparent or translucent areas on an otherwise opaque surface. The back of the dial is opaque The light from the bulb also passes along a guide 9, Fig. 1, of contrasting colour or intensity to a point 10 adjacent the perimeter of the dial to provide the fixed index mark referred to above. If the circuit of the bulb 1 includes a rheostat the intensity of illumination of the dial may be varied.
