Cold cathode ion source mated to quadrupole mass spectrometer for use as residual gas analyzer
Fixture facilitates inspection testing of circumferential pipe welds for vacuum tightness, using helium gas as a leakage tracer in conjunction with a mass spectrometer. It consists of a split rubber torus and a mating clamping ring with a vacuum hose fitting.
Interconnecting straight tube connects axially misaligned flanges in a duct assembly. It adjusts to accommodate variations in relative location of the flanges by pivoting. Adjustment is by spherical mating faces and a spherical-faced indexing swivel flange for bolting backup.
Split-screw grips for tensile testing provide uniform loading on the specimen shoulders. Holes in the heads enable the screws and specimen to be threaded as an assembly into a grip body, closely controlled guides and seats afford positive seating, and precision machining of mating surfaces minimizes misalignment effects.
Mechanism remotely controls de-mating of two bodies by unlock and withdrawal of one body from the other and, upon command, extends, locates, remates and relocks the two bodies. The system is designed to transfer fluids from a dispensing body to a receiving body.
Seal rings reduce cryogenic pump seal leakage under static and dynamic conditions. The rings are fitted into annular diaphragms, which are affected by cryogenic pressure and temperature, to move against a mating ring, to increase seal-bearing loads under static conditions.
Precision-finished lead screw and a fitted mating nut member produce a linear translatory motion. This motion is transformed to a rotary movement of a pivotal platform member. The transformation is achieved by coupling the nut member and the platform member through a pair of opposed, taut, flex bands.
Spring loaded insert protects electrical connector pins from being bent due to improper mating, or probing the pins with a screwdriver. This device modifies existing electrical connectors using only springs and retaining pins.
Electrical connector is fitted with an O ring, moisture-proof seal, is shielded in both the mated and unmated positions, and is equipped with one keying and three locking spheres.
Soft, cross-serrated aluminum shims are used as mating gaskets between uneven surfaces. Under pressure, the aluminum flows to conform with surface irregularities, forming a plane of uniform bearing.
Cable connector is developed in which each pair of contact elements is isolated by plastic cells and the mating interface is sealed by an elastic gasket. So insulated, the connector may be operated under high vacuum conditions at voltages up to 600 V ac without electrical leakage or intercontact ionization.
Triangular cutting tool uses carbide tips for notching heat-treated or abrasive materials, and alloys subjected to high structural stresses. The tool is rigidly mounted in a slot of mating contour to prevent deflection during cutting of tensile specimens. No other expensive machine equipment is required.
Connectors, which have 4 to 9 contacts, are engaged through a hole with a minimum diameter of 0.030 inch. They are constructed of concentric brass and nylon components assembled with a light, firm press-fit. They withstand several thousand mating cycles and each outer contact has a one ampere capacity.
Air-bearing-pad principle, combined with monitoring system of the air-bearing force, prevents damage between electrical and mechanical connectors joining a large engine system to the test stand during remote mating. Pad provides a cushion between engine and test stand.
Testing device monitors continuity and resistance of each circuit, it includes springloaded stationary fixture which holds plug, and moving fixture which is driven by small electric motor and is geared to mate and unmate connector 10 times per minute.
Devices are used in inspection of contact resistance in plated connectors after assembly into cables. System permits rapid inspection of connectors when mating connectors or special apparatus are not available, and enables source of excessive resistance to be precisely determined.
