摘要： A layer of material which absorbs incident focussed laser light and undergoes a resultant heating is arranged in the focal plane of a lens matrix. Laser light is projected onto such layer through the lens matrix itself. The laser light is focussed by the lens elements of the lens matrix onto the layer effecting a highly localized heating of small well-defined portions of the layer. At those small well-defined portions, the material of the layer, as a result of the highly localized heating, removes itself to form the apertures of a lens-aperture matrix which is thereafter used in cooperation with the lens matrix as a rear projection or daylight projection screen.

摘要： A laser system includes a nozzle assembly for use in directing a shielding gas around a laser beam and thereby protecting the point of focus from contamination by the atmosphere as is useful in welding and cutting applications. The nozzle includes a manifold section for admitting a shielding gas such as inert gas through a diffuser formed therein which exits from an outlet aperture through a nozzle tip section. The geometry of the nozzle is such that a certain amount of the shielding gas is flowed backward through an inlet aperture in the manifold section and thence into a housing container reflecting mirrors for directing and focusing the laser beam through the nozzle assembly. The remaining shielding gas, which is the bulk of the gas admitted, passes out through the outlet aperture in column fashion around the laser beam. By producing a back flow of shielding gas, aspiration of air through the housing and onto the workpiece is avoided. In addition, the necessity of having alternative means for preventing such aspiration in the form of windows or lenses closing off access to the housing is also prevented. The nozzle assembly is in two parts to facilitate interchanging of nozzle tips with the manifold, thereby providing a range of outlet opening sizes.
摘要翻译： 激光系统包括用于将保护气体引导到激光束周围的喷嘴组件，从而保护焦点免受大气中的污染，如在焊接和切割应用中有用的。 喷嘴包括歧管部分，用于通过形成在其中的扩散器通过喷嘴尖端部分从出口孔导出诸如惰性气体的保护气体。 喷嘴的几何形状使得一定量的保护气体通过歧管部分中的入口孔向后流动，并且从而进入用于引导和聚焦激光束通过喷嘴组件的反射镜的容纳容器。 剩余的保护气体是允许的气体的大部分，以列的方式通过出口孔径围绕激光束。 通过产生保护气体的回流，避免了通过壳体和工件的空气抽吸。 此外，还防止了防止以窗口或透镜的形式防止这种抽吸的替代手段关闭对壳体的通路的必要性。 喷嘴组件分成两部分，以便于将喷嘴头与歧管交换，从而提供一定范围的出口开口尺寸。

摘要： Hermetic sealing of battery containers is accomplished in such containers comprising metal bodies provided with flanges by first mating the bodies so the flanges are coextensive, planar resistance welding the bodies together through the flanges and subsequently peripherally laser welding the edges of the flanges together to effect a redundant weld and an hermetic seal.

摘要： A technique for ablating a metal workpiece by the use of laser beam radiation at an efficiency higher than heretofore possible and an improved regulation of the ablation process. Undesired side effects of the ablation process are eliminated by the entire and complete ejection of the molten metal at the point of beam impingement so that no material remains on the workpiece in the areas between contiguous points of ablation. The appropriate selection of beam intensity and the selection of pulse shape provide the inventive technique.

摘要： A method and apparatus for use in explosive welding of two components. The apparatus comprises an anvil for supporting the components during the explosion which is free to be accelerated away from the components, after the explosion has terminated, by the stored strain energy in the anvil. The anvil is so shaped and dimensioned that the compressive shock waves may travel from the interface between the components and the anvil to a free surface, and the resulting rarefraction shock waves may travel back to the interface in a time not less than it takes for the explosion to take place.

摘要： A method of producing ball joints of the type that include a ball and stem member pivotally mounted in a housing, the method comprising forming separate stem portions and ball portions and joining the portions at welded junctions with frictionally impored heat to provide pivot members of composite construction. Such pivot members are characterized by relatively large ball diameters as compared to the shank diameters so as to provide a high degree of angularity of movement.
