摘要： A machine for removing hairpin spikes from railroad ties includes at least one hairpin spike pulling tool supported by the machine frame, each tool being positioned on one side of the rail for pulling spikes on that side of the rail. Each of the pulling tools includes a lower end portion having a pair of exposed hooks curved toward the center of the pulling tool and abutted against each other in a pivoting relationship. Each pulling tool is supported for movement from a retracted position to a position wherein the curved hooks of that pulling tool are positionable under the loop-shaped head of a hairpin spike on opposite sides of the spike. The machine also includes apparatus for supporting the pulling tools for movement from the retracted position downwardly and toward the hairpin spikes into a position wherein the pulling tools engage the spikes with the curved hooks and then move upwardly to pull the spikes from the tie.

摘要： A multicell x-ray detector includes a chamber for confining a gas that produces electron-ion pairs incidental to absorbing radiation. A unitary multicell electrode assembly is mounted within the chamber. The assembly includes a plurality of electrode plates secured in first and second insulating members. A method is provided for bonding the electrode plates into the insulating members with a uniform distribution of adhesive which does not allow the adhesive to bridge between adjacent plates. The opposed ends of the plurality of electrode plates are inserted into grooves of the members. A relatively non-viscous liquid adhesive is brought into contact with one edge of each of the grooves of both members by a cellular applicator until the adhesive propagates by capillary action along the entire length of each groove. The cellular applicator and the adhesive are such that the adhesive has a greater adhesive attraction to the applicator than to the adjacent plates, and such that the adhesive has a lesser adhesive attraction to the applicator than to the grooves of the members. The adhesive will therefore flow from the applicator to the grooves of each member until each groove is filled and any excessive adhesive will be attracted back to the applicator, rather than to the adjacent plates of the assembly. The adhesive is then cured.
摘要翻译：多单元X射线检测器包括用于限制产生与吸收辐射相邻的电子 - 离子对的气体的室。单元多电极电极组件安装在腔室内。组件包括固定在第一和第二绝缘构件中的多个电极板。提供了一种用于以均匀分布的粘合剂将电极板结合到绝缘构件中的方法，其不允许粘合剂在相邻板之间桥接。多个电极板的相对端插入到构件的凹槽中。相对不粘的液体粘合剂通过细胞施加器与两个构件的每个凹槽的一个边缘接触，直到粘合剂沿着每个凹槽的整个长度的毛细作用传播。细胞施加器和粘合剂使得粘合剂对于施用器具有比相邻的板更大的粘合剂吸引力，并且使得粘合剂对于施用器具有比构件的凹槽更小的粘合剂吸引力。因此，粘合剂将从施加器流到每个构件的凹槽，直到每个凹槽被填充，并且任何过量的粘合剂将被吸引回到施用器而不是组件的相邻的板。然后将粘合剂固化。

摘要： A sorting conveyor for rail tie plates or the like including an inclined frame having an upper end and a lower end, and an endless conveyor belt formed of a plurality of links pivotally joined to each other. The links are designed to have plate retaining pockets formed thereon and the belt is adapted to travel a contoured path on the frame between the lower end and the upper end. The belt has an upper working strand and a lower slack strand. A hopper provides a supply of randomly oriented tie plates to the lower end of the conveyor which are agitated or tumbled by the action of the moving conveyor belt. At least one rejecter hook is provided to ensure proper positioning of the plates within the pocket. As the conveyor belt progresses towards the upper end of the frame, certain plates are oriented properly within the plate pockets and will be conveyed to the upper end of the frame through the movement of the conveyor belt. Plates which are not properly oriented are rejected from the conveyor belt by the rejecter hook which flings the plates back to the lower end of the conveyor for eventual proper placement within the pockets.

摘要： A machine for driving spikes into the ties of a railroad track includes a spike driving assembly movably disposed relative to a frame for gripping spikes and driving gripped spikes into the ties, the spike driving assembly having a spike pushing function and a spike percussive function. In the pushing function the spike driving assembly pushes the spike a specified distance into the tie by the application of constant pressure, and in the percussive function the driving assembly percussively completes the driving of the spike into the tie. An operator may selectively alternate between the pushing and percussive functions.

摘要： A multicell x-ray detector of the gas-filled ionization type includes a metal body in which the front, rear, end and bottom walls together with a sealed cover define a channel in which there is a row of spaced apart electrode plates which define cells in which ionization events and resultant analog signals are produced in response to absorption of x-ray photons by the gas. The x-ray entrance window is formed in the front wall and extends over substantially the length of the channel. The window has a curved cross section which permits restriction of its internal stresses to tensile stresses so its thickness and, hence, its x-ray absorption is minimized. The edges of the electrode plates which are presented toward the window are curved to be concentric with and slightly spaced from the window.

摘要： A multicell x-ray radiation detector includes a chamber for confining a gas that produces electron-ion pairs incidental to absorbing radiation. The chamber is formed by a channel having a bottom and sidewalls, one of the side walls having a window for admitting radiation to the chamber. A multicell unitary electrode assembly is mounted within the chamber. An upper compressed elastic member is interposed between the electrode assembly and the chamber and, similarly, a rear compressed elastic member is interposed between the assembly and the sidewall opposite the window of the chamber. The compressed elastic members interposed between the electrode assembly and the chamber isolate the electrode assembly from any mechanical vibration and thermal distortion of the chamber while maintaining a precise position of the electrode assembly to the chamber window.

摘要： A control system for providing power to independently driven wheels of a power driven cart for transporting medical diagnostic equipment. A manually engageable handle is mounted to the cart in a position allowing a person to exert a manual force on the handle in a direction in which it is desired for the cart to move. Force sensors are coupled to the handle to sense the manual force applied to it in a plane parallel to the plane on which the cart is to be moved. The force sensors provide signals representative of the magnitude and direction of the manual force applied to the handle in forward, reverse and turning directions. Electronic circuits are coupled to the force sensors for providing control signals to motors driving the wheels of the cart for independently controlling direction and velocity of movement of the cart.

摘要： A radiation detector is fabricated by the insertion into an arcuate support structure, a plurality of modules comprised of ceramic members with electrode plates disposed therebetween. Securing of the ceramic members to the support structure is accommodated by threaded fasteners which pass through the support section into inserts which are bonded into cavities formed in the ceramic members. Before installation of the module into the support structure, the modules can be tested and the better performing modules can then be installed in the central portion of the support structure.
