摘要： A method of repairing arthritic joints in which the bone surfaces of a knee, hip, shoulder, elbow or other articulation are cleaned of the inflammation caused by the arthritis without removing any of the bone of the joint, and then inserting into the joint a thin, dished bearing member of woven, high tensile strength material impregnated with high molecular weight polyethylene or equivalent material, and cementing one face thereof to the cleaned surface of the bone of one of the joint members, the opposite face of the bearing member being extremely smooth and polished so as to slide easily against the cleaned bone surface of the other joint member.In preparing the bearing member, a hard metal powder, finely divided, of low thermal expansion and high corrosion and acid resistance, is intimately mixed with a colloidal dispersion of the polyethylene material and applied, in several coatings, to the surface of the bearing member which will slide against the aforesaid bone surface of the other joint member, and the last coating is polished until adequately smooth.

摘要： A time delay gas generator for military missiles, characterized by very long shelf life and accurately-determined time delay. Time delay powder is layered at high pressure, and causes heating of a metal disc at the end of a time delay interval that is accurately known. Such heating ignites an output charged to generate gas, the gas breaking a closure and performing a function in the missile.

摘要： A delayed action switch embodied in a tubular casing adapted to be incorporated in a missile or a guided projectile. For example, the Redeye missile is activated by a soldier who keeps it against his shoulder. As he pulls the trigger, the missile takes off toward a specific target such as a tank, truck or the like, a distance of a few seconds away from the soldier. Should the missile drop near the soldier and explode, the soldier would be killed; but with the delay switch of this invention incorporated in the missile, it would be deactivated before it hits the ground. Consequently, the missile would be a "dud", a non functional device. In general, the switch of our invention includes, in succession within a tubular casing, a priming charge which is ignited when the missile is first propelled into the atmosphere, and which fires an ignition charge which in turn ignites a delay charge. The latter, in turn, after a predetermined delay, ignites a base charge which acts against a piston to propel it at high speed forwardly, causing it to cut a circuit when the missile has attained a high elevation in its upward travel. In a modified form of the invention, the piston is adapted to establish a circuit at the end of the delay charge burning.

摘要翻译： 一种延迟动作开关，其体现在适于引入导弹或引导射弹的管状壳体中。 例如，红帽导弹是由一个不服从他的肩膀的士兵激活的。 当他拉动扳机时，导弹朝向特定目标（例如坦克，卡车等）起飞，距离士兵几秒钟的距离。 如果导弹在战士附近下降并且爆炸，士兵将被杀害; 但是当本发明的延迟开关结合在导弹中时，它将在其撞击地面之前被停用。 因此，导弹将是一个“dud”，一个非功能的装置。 一般来说，本发明的开关在管状壳体内连续地包括一个起动装料，该导弹装置在导弹首先被推入大气中时被点燃，并引发点燃电荷，这又引发延迟电荷。 反过来，在预定的延迟之后，点燃一个基本的电荷，其作用在活塞上，以高速向前推进，导致当导弹在向上行进中达到很高的高度时切断电路。 在本发明的改进形式中，活塞适于在延迟充电燃烧结束时建立电路。

摘要： A piston, normally contained within a cylinder, is projected by electrical detonation of an explosive charge which is contained within the cylinder between the piston and a sealed end of the cylinder through which a detonation contact extends to the charge. A split ring, retained in an annular peripheral groove in the piston, is normally contained under compression within the cylinder, but is resiliently expandible to a diameter larger than the internal diameter of the cylinder when released therefrom by projection of the piston under the expanding gases of the detonated charge, and thereby becomes operative, by abutting engagement with the end of the cylinder, to lock the piston in its projected position, and to hold the reactive load of whatever machine part has been actuated by the piston.

摘要： A pin puller comprising a piston having a pull shaft extending from a cylinder in which the piston is slidable, is actuated by an explosive charge which, when ignited, develops a pressurized gas that is directed, through a transfer tube, into a chamber extending through the piston and into the piston shaft, from which it is directed outwardly through a port in the shaft into a sealed space behind the piston, to move the piston in a direction to exert a pull upon the shaft and a pull-actuated device connected thereto. The piston slidably receives the transfer tube and is sealed thereto to prevent short-circuit escape of the pressurized gas to the leading side of the piston. An electric circuit is provided for igniting the explosive charge when energized.

摘要： A piston, backed by a resilient disc, both slidable within a cylindrical case, is provided, on its leading end, with a penetrable conductor pellet, sheathed within an insulator cap. Upon firing of an explosive charge of disc form, arranged behind the piston with a polyethylene disc interposed between the charge and the piston, the latter will be driven forwardly against a pair of piercing points on the ends of a pair of conductor wires mounted in an insulator header in the leading end of the case, the driving force of the explosion being sufficient to cause the conductor wire points to pierce entirely through the insulator cap and to become embedded in the conductor pellet, thus closing a circuit across the conductor wires. A fusible bridge wire, embedded in the explosive charge, is fused by application of an electric current to a pair of conductors extending through an insulator header in the rear end of the case, the forward ends of these conductors being embedded in the explosive charge, and the fusible bridge wire being attached to these forward ends within the explosive charge, in bridging relation to the ends of these conductors.
