    • A beam of energy in a first form, such as electrons, is provided in a first direction. The beam may be pulsed or continuous. The beam is intercepted by a member, such as a converter target, to produce energy in a second form such as x-rays. The converter target may be formed from a heavy material such as tungsten or tantalum. The interaction of the electron beam with the converter target will produce energetic bremsstrahlung x-rays in an energy range including 10.6 Mev to approximately 13.0 Mev. This range is sufficient to excite the abundant nitrogen atoms in common explosives to induce the production of annihilation photons but is not sufficient to substantially excite atom of the most abundant elements of the earth's crust (e.g. oxygen, silicon, iron, aluminum, carbon, hydrogen, etc.), which comprise most common fabricated articles and soils. The converter target is disposed relative to an object (e.g. a suitcase in an airport) to obtain the production of energy in a third form, such as photons, from the object. The photons pass to a detector such as a scintillation counter which determines the concentration of the nitrogen in the object. The detector may be gated so as to be activated only when the photons are passing from the object to the detector. When the object is a suitcase which is moved along a conveyor, the detector may be downstream from the source in the direction of movement of the conveyor.

    • An autogenerating apparatus provides secondary intense relativistic current beam pulses in response to an injected beam pulse. One or more electromagnetic energy storage devices are provided in conjunction with gaps along a beam propagation path for the injected beam pulse. For injected beam pulses which are no longer than double the transit time of electromagnetic waves within the storage devices (which may be resonant cavities), distinct secondary beam pulses are generated by each of the energy storage devices. The beam propagation path, together with the one or more gaps provided therein, operates as a pulse forming transmission line cavity, in which the separate cavities associated with the gaps provide delays for electromagnetic waves generated at the gaps. After doubly traversing the cavity, the electromagnetic waves cause the gap to generate the secondary beam pulses, which are thus delayed by a time interval equal to the double transit time for the induced wave within the cavity.
    • 自动生成装置响应于注入的束脉冲提供二次强相对论电流束脉冲。 一个或多个电磁能量存储装置与用于注入的束脉冲的光束传播路径的间隙一起提供。 对于不超过存储装置(其可以是谐振腔)内的电磁波的传播时间的两倍的注入光束脉冲,由每个能量存储装置产生不同的次光束脉冲。 光束传播路径与其中提供的一个或多个间隙一起作为脉冲形成传输线腔进行操作,其中与间隙相关联的分离的空腔为在间隙处产生的电磁波提供延迟。 在双向穿过腔体之后,电磁波使间隙产生次级束脉冲,因此延迟等于空腔内感应波的双通道时间的时间间隔。

    • A method and apparatus for permanently and sealably connecting two duct sections, the duct sections having peripheral flanges forming opposite and corresponding halves of a composite, T-shaped peripheral flange extending outwardly from the duct sections. The composite flange has an upper cross-piece portion and a lower upright portion, the lower upright portion of the T-shaped flange containing a continuous reservoir of deformable gasket material. The method comprises the steps of first placing square-cornered, U-shaped clamps over the upper cross-piece portion of the T-shaped flange at spaced intervals thereon; secondly, pressing sides of each of the clamps inwardly and crimping the clamps to upper and lower surfaces of the upper cross-piece portion, forcing a portion of the gasket material to flow from the reservoir between the flange halves, towards the duct sections, thereby producing a sealed joint between the duct sections; and thirdly, rippling each of the clamps simultaneously with the upper cross-piece portion adjacent each of the clamps, causing undulations in both which prevent the clamps from slipping out of clamping contact with the upper portion of the T-shaped flange, thereby permanently connecting the duct sections.

    • A recombinant lead acid battery is provided having positive and negative plates coated with active material and separated by a compressible separator material containing an electrolyte. A casing provides structural support for the plates and encases the battery's components. The battery is preferably a recombinant lead acid battery with its plates being formed of lead foil sheets. The casing is reinforced and arranged to i) maintain a substantially evenly distributed compressive force on the separator material and ii) maintain a constant spacing between the plates. The battery is arranged to maintain a compressive force of at least eight psi on the plates which has been found to significantly reduce the incidence of premature capacity loss (PCL). By way of example, compressive forces in the range of 8-14 psi work well for conventional separator materials. In one embodiment, the casing includes a plurality of reinforcing support pins extending between upper and lower casing members through the plates and separator material for maintaining the evenly distributed pressure. Plates may be slacked one above another to provide a plurality of cells. A method of making the battery is also described.

    • An electron beam is generated in a packetized form defined by pulses having a duty cycle of less than 1:1000. Each pulse may have a width of approximately one microsecond (1 .mu.sec.) and may be separated by approximately one (1) second from the next pulse. The electrical beam may be accelerated, preferably linearly. The electrical beam may be modulated at a particular frequency (e.g. 3 gigahertz) by bunching the electrons during the beam acceleration. The electrons may be converted to photons (e.g. X-rays) by directing the electron beam to a target made from a suitable material (e.g. tungsten). The photons are then interacted with the electrical circuitry to produce photoelectrons. The photoelectrons impair the operation of the electronic circuitry by generating an electrical current in the electrical circuitry, generating capacitive charges in the circuitry and generating an electromagnetic field in the vicinity of the circuitry. The electrical circuitry may be disposed within an enclosure substantially impervious to the penetration of external electromagnetic fields, but passing energetic photons (x-rays). The enclosure may resonate at the modulating frequency. This invention is primarily intended to be used for experimental purposes to determine how the electrical circuitry may be protected to prevent the electrical circuitry from being operationally impaired by photons passing to the electrical circuitry.
    • 以占空比小于1:1000的脉冲限定的分组形式产生电子束。 每个脉冲可以具有大约1微秒(1μs)的宽度,并且可以与下一个脉冲相隔大约一(1)秒。 电子束可以被加速,优选是线性的。 可以通过在光束加速期间聚束电子,在特定频率(例如,3千兆赫兹)下调制电波。 通过将电子束引导到由合适的材料(例如钨)制成的靶上,可以将电子转换成光子(例如X射线)。 然后光子与电路相互作用以产生光电子。 光电子通过在电路中产生电流来损害电子电路的操作,在电路中产生电容性电荷并在电路附近产生电磁场。 电路可以设置在基本上不透过外部电磁场穿透的外壳中,但是通过能量光子(x射线)。 外壳可能以调制频率谐振。 本发明主要用于实验目的,以确定如何保护电路以防止电路被传递到电路的光子的操作上受损。
