摘要： A multifrequency, broadband, dual-polarized corrugated conical horn antenna is simultaneously fed a multiplicity of signals, two for each of five frequencies, with each of a pair of signals fed in each of two orthogonal planes for excitation of a desired spherical hybrid mode (HE.sub.11). The lowest frequency is fed into the horn through orthogonal pairs of colinear slots, each pair being fed by coaxial tee power dividers. Other signals are fed through a circular waveguide connected to the vertex. Band reject cavities block the next higher frequency from passing through the low frequency feed slots. The highest frequency signals are fed through orthogonal ports near the far end of the circular waveguide. The intermediate frequency signals are fed through orthogonal ports spaced along the waveguide. Filtering is incorporated for each to maintain isolation and low insertion loss, a quarterwave step transformer is used between the highest frequency (37 GHz) ports and the two next lower frequencies (21 GHz and 18 GHz) to provide a short circuit for these two lower frequencies, and a TM.sub.11 mode generator for the highest frequency is used as a short circuit for the next lower frequency (10.69 Ghz).
摘要翻译：多频，宽带，双极化波纹锥形喇叭天线同时馈送多个信号，两个为五个频率中的每一个，一对信号中的每一个馈送在两个正交平面中的每一个中，用于激发期望的球面混合模式（ HE11）。最低频率通过正交对的共线插槽馈送到喇叭中，每对由同轴三通功率分配器馈送。其他信号通过连接到顶点的圆形波导进给。频带拒绝腔阻止下一个较高频率通过低频馈送槽。最高频率信号通过靠近圆形波导的远端的正交端口馈送。中频信号通过沿着波导间隔开的正交端口馈送。为了保持隔离和低插入损耗，集成滤波器，在最高频率（37 GHz）端口和两个下一个较低频率（21 GHz和18 GHz）之间使用四分之一波长级变压器，为这两个低电平频率和最高频率的TM11模式发生器用作下一个较低频率（10.69 Ghz）的短路。

摘要： An improved motor speed and torque controller for brushless DC motors which provides an unusually smooth torque control arrangement. The controller provides a means for controlling a current waveform in each winding of a brushless DC motor by synchronization of an excitation pulse train from a programmable oscillator. Sensing of torque for synchronization is provided by a light beam chopper mounted on the motor rotor shaft. Speed and duty cycle are independently controlled by controlling the frequency and pulse width output of the programmable oscillator. A means is also provided so that current transitions from one motor winding to another is effected without abrupt changes in output torque.

摘要： A method for installing fragile, high temperature insulation batting in an elongated cavity or in a resilient wire sleeve to form a resilient seal. The batting is preformed to rough dimensions and wrapped in a plastic film, the film being of a material which is fugitive at a high temperature. The film is heat sealed and trimmed to form a snugly fit skin which overlaps at least at one end to permit attachment of a pull cord. The film absorbs the tensile force of pulling the film enclosed batting through the cavity or wire mesh sleeve and is subsequently driven off by high temperature baking, leaving only the insulation in the cavity or wire mesh sleeve.

摘要： A subcutaneous electrode structure particularly suitable for a chronic implant and for taking a low noise electrocardiogram of an active animal such as a rat, dog, monkey, cow or the like, comprises a thin inflexible, smooth disc of stainless steel having a diameter as of 5 to 30 mm, which is sutured in place to the tissue of the animal being monitored. The disc electrode includes a radially directed slot extending in from the periphery of the disc for approximately 1/3 of the diameter. Electrical connection is made to the disc by means of a flexible lead wire that extends longitudinally of the slot and is woven through apertures in the disc and held thereto at the terminal end by means of a spot-welded tab. Within the slot, an electrically insulative sleeve, such as silicone rubber, is placed over the wire. The wire with the sleeve mounted thereon is captured in the plane of the disc and within the slot by means of crimping tabs extending laterally of the slot and over the insulative wire. The marginal lip of the slot area of the disc is apertured and an electrically insulative potting material, such as silicone rubber, is potted in place overlaying the wire slot region and through the apertures in the electrode.

摘要： An improved cryostat for use in a low or a substantially gravity-free environment adapted to cool an experiment through the use of helium II, or helium in its super fluid state. The cryostat is characterized by a plurality of interchangeable daughter dewars and helium supply or mother dewar having connected therewith a low pressure venting system for converting helium I contained therein to a super fluid state for use as a primary cryogen. Each daughter dewar is adapted to be removably mounted in mated relation on the mother dewar and is characterized by a support for an experiment package, a source of helium to be employed as a secondary cryogen, and a heat pipe suspended therefrom and adapted to be extended into the mother dewar for facilitating cooling of the secondary cryogen whereby a transfer of heat from the package to the primary cryogen, via the secondary cryogen, is accommodated as a film flow of helium II progresses from the heat pipe to the experiment dewar.
