摘要:
The present invention relates to a clamping device for joining two waveguides used for propagating microwaves. The waveguides are of the type comprising hollow microwave propagation channels having at their meeting ends connection flanges in abutting relationship, the flanges being provided with aligned openings. The clamping device comprises a top wall and a pair of generally parallel side walls depending from the top wall. A metallic pin is mounted to one of the side walls and projects toward the other side wall which is provided with a cut-out portion facing the pin. In use, the pin is inserted through a pair of aligned openings in the flanges and the clamping device is pressed toward the flanges to turn about the axis of the pin until the flanges are deeply received between the side walls.

This disclosure relates to connectors used in joining rigid inner sections of high energy conducting coaxial transmission lines and distinguishes over the existing state of the art by providing a one contact surface joint which, while permitting the desired axial expansion and contraction movements inherent in those structures, avoids the well known problem of galling dust accumulations by including as an integral part of the connector, a receptacle for capturing this dust and associated particle matter.

A range pole and in-line detachable battery module assembly including a range pole (10) with an elongated tubular range pole shell (102) which has a female cap assembly (108) and a male cap assembly (26) at opposite ends. A detachable battery module (12) includes a tubular battery-module shell (24) which has a male cap (26) at one end that is adapted to mate with female cap assembly 108. A detachable tip (14) includes a ribbed aluminum tip body (150) having external ribs (152) formed in the sides thereof and a stainless steel tip (160). The male cap assembly (26) at the other end of the range pole (10) is to be used for connection to other equipment. In the present embodiment, the male cap assembly (26) at the top end of the range pole is coupled to a GPS antenna/receiver (16).
摘要:
An electrical conducting, fluid tight, tubular assembly comprising a number of elongate, interchangeable, reusable tubular sections that may be removably connected end to end and extended downwardly in an oil well bore hole adjacent a tubing string situated therein to supply electrical power to a down hole electrical pump or other electrically operated device that may be situated in the bore hole. The assembly is concurrently made up as the tubing string is lowered into the bore hole, with the sections being clamped to the tubing string and supported therefrom. The sections of the tubing string are longitudinally movable relative to one another within predetermined limits and as a result the assembly may elongate and contract in conformity with changes in the longitudinal length of the tubing string due to temperature changes in the bore hole. When the tubing string is pulled from the oil well bore hole the sections of the tubular assembly are sequentially unclamped therefrom and disengaged from one another. The disengaging of the sections one from the other is extremely simple, as the sections are in slidable engagement and the uppermost sections on an assembly simply has to be lifted upwardly to effect such disengagement. The tubular sections when assembled provides protection for a number of longitudinally extending laterally spaced electrical conductors or cables therein, both from mechanical damage, as well as damage that may result from excessive temperatures or gas pressure in the bore hole.

A flangeless feed through supplies power to a device through a passage in a wall of a vacuum chamber. The feed through includes an insulator ring securely positioned in the passage, a first threaded insert, and a second threaded insert which engages the first threaded insert, wherein the insulator ring is gripped by the first and second threaded inserts. The feed through is installed by securely positioning the insulator ring within the passage, inserting the first threaded insert into the passage, and then connecting the first and second threaded inserts to grip the insulator ring.
