Abstract: 780,068. Measuring times of energization and de-energization of relays. TESLA, NARODNI PODNIK. March 1, 1954, No. 5929/54. Class 37. [Also in Groups XXXVII and XXXVIII] An apparatus for measuring the time of energization and de-energization of relays comprises a valve 6 through which condenser 23 is charged during a period determined by a pair of control valves 4, 5 only one of which can conduct at a time. The relay winding is connected between the points 1, 2 and the contacts to points 17, 18 (contact 16 being closed) if they are open at the start of the measurement and to points 19, 20 (contact 16 being open) if they are closed. When energization time is being measured, switch 15 is in its upper position. The test is initiated by closing contact 29 whereupon the relay begins to energize, valve 4 conducts and valve 5 stops conducting and as a result the charging valve 6 becomes conducting. When the relay is energized, the charging valve ceases to conduct either because its grid is con. nected to a blocking potential at 36 via 17, 18 or because a blocking potential is acquired by the upper contact of switch 15 when the anode supply to valve 5 is interrupted at 19, 20. When de-energization time is being measured, switch 15 is in its lower position and the functions of valves 4 and 5 are transposed, the measurement being initiated by opening switch 29.

Abstract: 962,484. Gas burners. MAIN MORLEY Ltd. Jan. 11, 1963 [Feb. 15, 1962], No. 5947/62. Heading F4T. In a gas-fired appliance having a main burner 12 ignited by a gas pilot jet 25 which in turn is lit by an igniter gas jet 30, a rod 32 having a push-button 33 is operated to energize an electric element 31 to light the igniter and to open a valve 39 controlling the flow of gas to the main burner and the pilot jet, and maintained open by an electromagnet 46 energized by a thermocouple 47 heated by the pilot jet flame. Operation of the rod 32 also closes a valve 37 so that gas supplied through an inlet 18 passes through the open valve 39 into an axial passage 14 having branched passages 21, 22 which communicate with the pilot and igniter jets 25, 30 but is prevented from passing through a connection 20 to the main burner 12. A ball valve 28 disposed in the igniter gas passage 22 is opened by a slidable rod 36 engaged by a cone 35 fixed to the rod 32. When the rod 32 is released the ball valve 28 closes, cutting-off the supply to the igniter jet, the element 31 is de-energized and the valve 37 opens to allow gas to pass from the passage 14 to the main burner. The valve 39 is automatically closed by a spring 40 if the pilot jet is extinguished or manually closed by depression of a push-button 55 which moves a flexible cable 56 and rod 58 to push the valve 39 away from the electromagnet 46. Alternatively, the button 55 may be attached to a push-rod which abuts one end of a spring- urged pivoted lever the other end of which engages the yalve 39 when the button is depressed.
