    • An x-ray tube includes an anode, a cathode, and an electrode disposed in an evacuated envelope. The electrode is positioned such that the electrode is remote from an area in immediate proximity to the envelope. An electric field defined by electrode is of sufficient strength such that arcing preferentially occurs between the electrode and the anode as opposed to occurring between the cathode and anode. The electrode is further situated such that metal sputtered from the electrode substantially falls in a define region on the anode and serves as an active getter for pumping gas from the envelope. The electrode is composed of an active metal which, upon being passively heated by the anode, also acts as a getter material to aid in pumping gas from the envelope.
    • X射线管包括阳极,阴极和设置在抽真空的外壳中的电极。 电极被定位成使得电极远离紧邻信封的区域。 由电极限定的电场具有足够的强度,使得在电极和阳极之间优先发生电弧,而不是发生在阴极和阳极之间。 电极进一步定位成使得从电极溅射的金属基本上落在阳极上的限定区域中,并且用作用于从封套泵送气体的主动吸气剂。 电极由活性金属组成,其在被阳极被动加热时也用作吸气剂材料以有助于从封套泵送气体。

    • A plastic molded snap fastener including a stud head having solid thin annular base flange and a top, the top and the flange being held in spaced relation by radial ribs preferably in the form of a cross piece, the top being annular but "flattened" on the outer perimeter in the area of the ends of the cross piece. Where the plastic is compatible with the plastic of the fabric, the fastener parts may be molded directly on the fabric. In a modification the base flange is split by a plane perpendicular to the axis of the fastener part. The base fabric is sandwiched between the parts of the flange. This modification is useful where the plastic of the fastener is not compatible with the plastic of the fabric. The invention also includes a mold apparatus for forming the fastener on a stip of fabric wherein core pins on one side of the mold cooperate with spring-pressed ejection pins on the other side and with cavities in the mold retainer plates to shape the parts. The preferred mold apparatus also includes punches for perforating the fabric preparatory to the molding operation.
    • 一种塑料成型的卡扣紧固件,包括具有实心薄的环形底部凸缘和顶部的螺柱头,顶部和凸缘通过径向肋保持间隔开,优选地为横截面形式,顶部是环形的但是“扁平化”在 横截面端部区域的外周。 当塑料与织物的塑料相容时,紧固件部件可以直接模制在织物上。 在一个变型中,底部凸缘由垂直于紧固件部分的轴线的平面分开。 底布被夹在凸缘的部分之间。 当紧固件的塑料与织物的塑料不相容时,该修改是有用的。 本发明还包括一种用于在织物制成的紧固件上形成紧固件的模具装置,其中模具一侧的芯销与另一侧上的弹簧压出的销钉配合,并且具有模具保持板中的空腔以使零件成形。 优选的模具设备还包括用于对准备模制操作的织物进行穿孔的冲头。

    • A fuel ignition system for a heating apparatus includes a burner connected to a fuel supply, a valve for regulating the flow of fuel to the burner, an electrode assembly for producing a spark to ignite the fuel at the burner, an ignition system control module having input and output terminals for controlling the operation of the valve and the electrode assembly in response to a temperature-actuated device, the system control module producing output signals to open the valve and activate the electrode assembly for a predetermined time period to ignite the burner and locking in a non-operable mode to close the valve and deactivate the electrode assembly if the burner fails to ignite within the predetermined time period, and an automatic reset control for activating the system control module after a time-delay period. The automatic reset control includes a timer for determining the time-delay period having an input terminal and an output terminal and a function control including two triggerable bidirectional switches for activating the system control module and for activating and deactivating the timer. A first bidirectional switch is triggered by an output signal produced by the system control module to activate the timer when the valve is closed and to deactivate the timer when the valve is open. A second bidirectional switch is triggered by an output signal produced by the timer to activate the system control module after the time-delay period.
    • 一种用于加热设备的燃料点火系统包括连接到燃料供应器的燃烧器,用于调节燃烧器的燃料流的阀,用于产生火花以点燃燃烧器处的燃料的电极组件,点火系统控制模块,其具有 输入和输出端子,用于响应于温度驱动装置控制阀和电极组件的操作,系统控制模块产生输出信号以打开阀门并激活电极组件预定的时间段以点燃燃烧器, 如果燃烧器在预定时间段内不能点燃,则锁定非可操作模式以关闭阀门,并且使电极组件停用,以及在延时周期之后启动系统控制模块的自动复位控制。 自动复位控制包括用于确定具有输入端子和输出端子的时间延迟周期的定时器和包括用于激活系统控制模块并用于激活和停用定时器的两个可触发双向开关的功能控制。 第一个双向开关由系统控制模块产生的输出信号触发,以在阀门关闭时激活定时器,并在阀门打开时停用定时器。 第二个双向开关由定时器产生的输出信号触发,以在延时周期之后激活系统控制模块。

    • A three-piece nozzle is disclosed, for fitment to a hand actuated liquid pump having a barrel portion with a bore therethrough for passage of liquid. The nozzle features an integrally formed nozzle cap which fits around the end portion of the barrel. Enclosed within the nozzle cap is an integrally formed nozzle seal which forms a peripheral liquid-tight seal around the barrel between the nozzle cap and the barrel. Also provided is an integrally formed check valve which is movably positioned at the mouth of the bore and which is biased towards the mouth of the bore to form a liquid-tight bore seal. The bias is overcome, to open the liquid-tight bore seal, upon actuation of the pump which provides liquid pressure in the bore to act against the check valve.
