    • An automated ignition assembly for a gas-fueled appliance includes a pressure plate positioned between an upper bellows and a lower bellows, each of which is in selective communication with a fuel gas source. If fuel gas is directed to the lower bellows, gas within the upper bellows is diverted to an ignition site; as the lower bellows inflates, it lifts the pressure plate and an associated linkage assembly to engage a piezo igniter, which creates a spark at the ignition site. The lower bellows is then deflated and the upper bellows is inflated to again engage the piezo igniter. Once a flame has been generated, or if a flame has not been generated within a predetermined time period, an automated valve disables fuel gas flow to the bellows.
    • 用于燃气燃料的设备的自动点火组件包括位于上波纹管和下波纹管之间的压力板,每个波纹管与燃气源选择性连通。 如果燃料气体被引导到下部波纹管,则上部波纹管内的气体转移到点火站点; 当下部波纹管充气时,它提升压力板和相关联的联动组件以接合压电点火器,这在点火现场产生火花。 然后将下部波纹管放气,并将上部波纹管充气以再次接合压电点火器。 一旦已经产生火焰,或者如果在预定时间段内没有产生火焰,则自动阀禁用燃料气体流向波纹管。

    • Quantitative refracture diagnostic and fracture-injection/falloff models may be used in methods for oil and gas subsurface formation evaluation techniques. More particularly, such methods may be used to select candidate wells and well candidate layers for stimulation treatments in a subterranean formation. An example of a method for selecting well candidate layers for stimulation treatments in a subterranean formation may comprise the steps of: selecting a candidate well; selecting a reservoir layer to be tested; performing a quantitative refracture-candidate diagnostic test on the reservoir layer; determining at least one reservoir property of the reservoir layer using the quantitative refracture-candidate diagnostic test; and modeling a proposed stimulation treatment using the at least one reservoir property in a reservoir simulation model so as to predict the efficacy of the proposed stimulation treatment.
