US Patent:

39760995, Aug 24, 1976

Filed:

Sep 30, 1974

Appl. No.:

5/510472

Inventors:

Duane K. Russell - Bothell WA

Assignee:

Western Gear Corporation - Everett WA

International Classification:

F16L 2900

US Classification:

13761401

Abstract:

A rigid, multiple-passage, quick-disconnect coupling in which valves of a supply section of the assembly are moved to mechanically open valves in a receiver section for enabling pressurization of telescopic cylinder sections. Energization of the innermost cylinder section automatically actuates the valves for enabling pressurization of the remaining cylinder sections. The coupling sections have opposed valve surfaces substantially flush with the surrounding surfaces of the coupling sections.

Abstract:

1. In a monopulse radar receiver system for determining the angular co-orates of a pulsed RF radiation source, the combination comprising: An RF signal processing circuit adapted to convert a directional antenna input signals to inversely related pairs of computer input pulses; A pair of automatic gain control pre-amplifiers connected to said processing circuit adapted to simultaneously receive and amplify the pairs of input signals; A difference circuit connected between the outputs of each pair of pre-amplifiers for providing a difference signal pulse; Amplifying means connected with said difference circuit for amplifying said difference signal pulse; A leading-edge gate circuit connected with said amplifying means, adapted to be operatively triggered at the pulse-repetition rate of the pulses propagated by the RF radiation source for accepting only the leading edge of each amplified difference signal pulse; Means for triggering the gate circuit; A pulse integrator circuit connected with the output of said gate circuit adapted to provide an output signal which is a function of the position of the source of radiation; Direct connecting means joining the output of said integrator with one pre-amplifier of said pair for directing the integrator output signal to the one pre-amplifier for dirving the gain thereof in a first direction; An inverter circuit connecting the output of said integrator with the other pre-amplifier of said pair, adapted to invert and combine a reference voltage with the output of said integrator circuit to provide an inverted gain control signal having a reference imposed thereon for driving the gain of the other pre-amplifier in a second direction opposed to said first direction; and A second difference circuit connected with the output of said integrator and the output of said inverter circuit for deriving a difference signal indicative of the angular co-ordinate of the source of pulsed RF radiation, relative to said system, when the difference signal is driven to a zero valve.

Appl. No.:

5/742278

Inventors:

Duane K. Russell - Bothell WA

Assignee:

Western Gear Corporation - Everett WA

International Classification:

E21B 1914

US Classification:

175 52

Abstract:

A two-ram hydraulic drilling rig is provided with a lateral support frame. The rams have rods connected through a tension structure with a power swivel. The power swivel has a removable swivel stem assembly for allowing through-swivel positioning of drill pipe, particularly for tripping.
