[Also in Division H2] A gas-fueled lighter comprises a single piezoelectric element 13, or an additional element 26, within an insulating plastics sleeve 27, the element(s) and a metallic head 23 being maintained under compression by a bar 31 which acts to concentrically guide a hammer 14 relative to the elements. A backing plate 28 and components 26, 13, 23 and 31 are all retained within a rectangular frame 116 which is mounted between base 17 and top wall 10f. In operation of the lighter button 16 is depressed and stem 121 lowers a hook 37 pivoted to it and tensions a return spring 122. As hook 37 is depressed it will contact a sleeve 34 attached to the hammer and cause the hammer to slide down bar 31, compressing spring 29. Hook 37 is normally urged to remain in contact with sleeve 34 by a wire spring 124 but as the hammer reaches the end of its travel spring 29 acting on the hammer overcomes spring 124 and the hook is forced to release the hammer which then moves up with spring 29 and strikes the piezo-electric assembly. A voltage generated cause a spark between electrodes 110 and 111. Electrode 110 is connected to the piezo element(s) via a conductor 109 which contains a resistor 108. Electrode 111 is connected to the piezo element(s) via a support arm 114 and lighter casing 10. As button 16 is depressed a pivoted lever 43 raises and opens fuel valve 11. Burner nozzle 20 is surrounded by a flame guide 19 and combustion air is drawn in through holes 10c in the casing. When button 16 is released it is returned to its initial position by spring 122. The compressive force exerted on the piezo element(s) by the bar 31 can be varied by rotating a nut 32 threaded on its lower end and in contact with flame 116. In a modification, Fig. 7 (not shown), a gas distributer fitted on to burner nozzle 20 is formed with main and auxiliary gas openings, and the spark electrodes are situated adjacent the auxiliary opening.

Abstract: 1363684 Automatic temperature control TRANE CO 28 Oct 1971 [4 Nov 1970] 50211/71 Heading G3R In apparatus for delivering air at a substantially constant temperature to a zone, the rate of air delivered is varied according to the temperature of the zone, the rate being limited to a predetermined maximum value that is independent of the zone temperature. In an embodiment, air at a substantially constant temperature is fed to a zone e.g. a building at a rate varied by a damper 13, which is controlled by a bi-metal thermostat 52 in the zone, the thermostat control being over-riden if a pre-set flow-rate is exceeded. The position of damper 13 is controlled by thermostat 52 through motors 19, 20, which are energized from supply transformer 51 via a contact of switch 38. A pressure responsive device 32, connected by pilot tubes 30, 31 to the air-flow, changes the state of switch 38 at a flow-rate maximum, pre-set by screw 43, thus over-riding the thermostat 52 and moving the damper such that the flow-rate returns to within designed operating limits, when the damper is again thermostatically controlled. The air may be below or above the zone temperature i.e. used to cool or heat the zone respectively. To prevent hunting about the pre-set flowrate maximum, the pressure responsive device 32, Fig. 2 (not shown) may actuate a further switch (39) Fig. 3 (not shown) sequentially after switch 38, such that at the pre-set maximum flow-rate switch 38 is opened to terminate the supply to damper opening motor 20, and if the flow-rate rises above the pre-set value, damper closing motor 19 is energized by the closing of switch 39 until the flow-rate falls to the pre-set value.
