摘要： A multifilar flexible rotary shaft includes a plurality of individual filaments which are not wound around each other or around a central core, a loose ensemble of filaments. The input ends of each filament are coupled to each other and the output ends of each filament are coupled to each other. Preferably all of the filaments are identical. A loose ensemble of N filaments can transmit N times the torque of a single filament, and will have N times the torsional stiffness of a single filament, while retaining the minimum radius of operation of a single filament. Since a loose ensemble of filaments does not have any appreciable contact forces among the filaments (because they are not forcibly twisted together), there is no appreciable internal friction or hysteresis. In order to appreciably eliminate all the hysteresis in such an ensemble of filaments, the filaments should be no more than loosely twisted together, if at all. The only reason for loosely twisting the wires together is to allow the ensemble to be easily handled and to insure that the individual wire filaments follow the same general curved path from one end to the other. Several practical applications of the invention are also disclosed.
摘要翻译： 多针柔性旋转轴包括多个单独的细丝，它们彼此不缠绕或围绕中心芯，松散的细丝组合。 每个灯丝的输入端彼此耦合，并且每个灯丝的输出端彼此耦合。 优选地，所有的长丝是相同的。 N细丝的松散组合可以传播N倍的单丝的扭矩，并且将具有单丝的扭转刚度的N倍，同时保持单丝的最小操作半径。 由于长丝的松散组合在细丝之间没有任何明显的接触力（因为它们不被强制扭曲在一起），所以没有明显的内部摩擦或滞后。 为了明显地消除这种灯丝组合中的所有滞后现象，如果有的话，灯丝不应该松散地扭曲在一起。 将电线松散地缠绕在一起的唯一原因是允许集合容易地处理并且确保单个线丝沿着从一端到另一端的相同的一般弯曲路径。 还公开了本发明的几个实际应用。

摘要： A hybrid rocket motor includes a storage tank which stores an oxidizer under relatively low pressure, a turbopump preferably directly coupled to an outlet of the storage tank which pressurizes the oxidizer to a relatively high pressure, a combustion chamber including a solid fuel, and an injector between the turbopump and combustion chamber through which the oxidizer is injected into the combustion chamber. According to a preferred aspect of the invention, the turbopump is operated by an expander cycle of a heat exchanger. According to another preferred aspect of the invention, the fluid flowing through the heat exchanger is oxidizer tapped from the storage tank. A barrier is maintained between an oxidizer feed line from the turbopump and the injector until sufficient pressure is created by the turbopump to pump the oxidizer at the requisite pressure into the injector.

The first end portion is preferably frustroconical and flares diametrically outward to form the stop flange which has a first diameter. The waist or groove has a second diameter which is smaller than the first diameter. The tapered locking flange is also preferably frustroconical and tapers diametrically inward from a third diameter which is larger than the second diameter. Each of the legs is inclined diametrically outward and includes a plurality of coil engaging ribs on its inner surface. The outer surface of each leg is preferably provided with a longitudinal key and the free end of each leg is preferably tapered radially inward. The collar has a throughbore which extends through the first end portion to the space between the legs. An endoscopic instrument actuator and a clevis for use with the snap-fit collar each include a throughbore having a step and a pair of diametrically opposed keyways which extend into at least a portion of the throughbore wall.

摘要： A cautery probe is described for use with an endoscopic instrument where the endoscopic instrument has an electrical contact located therein. The probe includes an insulated handle which extends out of the instrument, a conductive probe element which is mounted in the insulated handle and extends through the distal end of the endoscopic instrument, and an insulating cover. The conductive probe element has a distal cautery surface, and an electrical contact surface at a location between the proximal end of the conductive probe and the distal cautery surface, with the electrical contact surface contacting the electrical contact in the endoscopic instrument when said cautery probe is inserted in the endoscopic instrument. The insulating cover substantially covers the conductive probe element from the insulated handle up to but not at the electrical contact surface, and substantially covers the probe element from a point beyond the electrical contact surface, up to but not at the distal cautery surface. Preferably, the cannula of the endoscopic instrument is used as the electrical contact, and the electrical contact surface of the probe element is a bump which contacts the cannula.
