  • Patent number: 4720909
    Abstract: An improved power-switching relay especially designed for mounting on printed circuit boards together with a method for manufacturing such a relay. The relay includes a number of features designed to properly position the various relay components relative to one another and to help ensure that they remain in the proper position at all times. To this end, the relay includes a unitary bobbin (22) and stationary contact support header (33) together with means (64) for firmly retaining the stationary contacts (34, 36) and their terminals (63, 73) in place in the header. The relay also provides means to prevent rotation of the armature relative to the movable contact assembly (53, 54) and to prevent rotation of the coil assembly relative to the frame (35). According to a further aspect of the invention, the core and coil assembly is attached to the relay frame by extending the core through the coil assembly and press-fitting the core into an extruded hole (14) in the frame.

  • Patent number: 4672750
    Abstract: A tool for the measurement and inspection of tolerances in pipe threads on pipes and couplings, etc. formed as a pair of pivoting jaws having handles. One of the jaws includes an assembly of probes mounted for longitudinal displacement in a direction normal to the longitudinal axis of the pipe or coupling, the probes also being slideably supported within the assembly for transverse displacement in a direction parallel to the longitudinal axis of the pipe. Transducers are provided for measurement of the motion of the probe. The second jaw coacts with the first jaw for clamping action, the probes are displaced transversely so as to set into troughs of the threads whereby the probes are aligned for measurement of thread length. The taper is measured by means of an inclinometer disposed at the end of the assembly away from the probes. Normal displacement measures thread height as well as deviation in diameter, the latter providing a measure of the non-linearity of the thread pitch line.

  • Patent number: 4604198
    Abstract: A multicartridge chromatography cartridge housing for use in supporting several chromatography cartridges in a parallel array is disclosed. A number of elongated cylindrical cartridge holders extend between a lower support plate and an upper support plate. Each such cartridge holder receives a chromatography cartridge which is held within the holder by suitable end caps and tie rods. Several truss rods serve to space the support plates from each other and to support the housing assembly. Fluid flow manifolds are secured to the lower and upper support plates and serve to distribute the fluid to, and consolidate the fluid received from the cartridges within the individual holders. The multicartridge chromatography cartridge housing in accordance with the present invention handles high fluid flow volumes with a small pressure drop and with a minimum hold up volume.

  • Patent number: 4550605
    Abstract: The invention relates to nondestructive inspection apparatus for automatically inspecting the end region of a tubular member and a coupling member secured to that end region. An inspection probe is yieldingly received within a housing that is pivotally supported on an arm that moves helically around the tubular member. The probe is extended outwardly from an air chamber in the housing to contact the surface of the tubular member. When the probe encounters the obstructing shoulder of the coupling on the end of the tubular member, the housing is caused to pivot to activate an air escape mechanism to reduce the air pressure in the chamber and cause the probe to be withdrawn radially to hop over the obstructing shoulder on the coupling. The housing then returns to its original position to terminate the air escape from the chamber. Air pressure builds up again to force the probe outwardly onto the surface of the coupling.

  • Patent number: 4551806
    Abstract: A method and apparatus for simulating the manner in which a ribbon of known profile is wrapped around a carcass of known profile in accordance with a predetermined winding specification is disclosed. The profile of the ribbon, the profile of the carcass and the winding specification are stored in a memory together with the desired final profile of the ribbon build. The profile of the final ribbon build, which will be created at a selected cross-section of the carcass when the ribbon is wrapped around the carcass in accordance with the winding specification, is calculated. The final ribbon build so calculated is displayed on a video display which also displays the desired final profile so that the profile created by the predetermined winding specification can be compared to the actual profile which will be produced by the winding specification.

  • Patent number: 4462469
    Abstract: A motor for driving a rotary drilling bit within a well through which mud is circulated during a drilling operation, with the motor being driven by a secondary fluid which is isolated from the circulating mud but derives energy therefrom to power the motor. A pressure drop in the circulating mud across a choke in the drill string is utilized to cause motion of the secondary fluid through the motor. An instrument which is within the well and develops data to be transmitted to the surface of the earth controls actuation of the motor between different operating conditions in correspondence with data signals produced by the instrument, and the resulting variations in torque in the drill string and/or the variations in circulating fluid pressure are sensed at the surface of the earth to control and produce a readout representative of the down hole data.
