  • Patent number: 6204005
    Abstract: The present invention provides a method for determining qualitatively or quantitatively the presence of toxic congeners of polychlorinated biphenyl in a test sample. The method includes the steps of: providing a known quantity of antibodies to the toxic polychlorinated biphenyl congener; providing a competitor that will bind to said antibodies in competition with the toxic polychlorinated biphenyl congener and having a lower affinity to said antibodies than said antibodies have to the toxic polychlorinated biphenyl congener; incubating said antibodies and said competitor in the presence of a test sample; and detecting the presence of the toxic polychlorinated biphenyl toxic congener in the test sample.

  • Patent number: 4773497
    Abstract: An improved mounting arrangement for a ball nut drive assembly for a linear actuator is disclosed. The invention is described as embodied in an electric assist steering system. The steering system includes a housing surrounding at least a portion of a steering member having rack teeth thereon, a ball-nut drive assembly circumscribing a thread portion of the steering member for axially driving said steering member upon rotation of the ball-nut drive assembly, an electric assist motor for driving said ball-nut assembly into rotation in response to a control signal and an electronic control unit for providing said control signal in response to a measured amount of driver input torque. The steering member is radially supported relative to the housing at two spaced apart locations. The ball-nut drive assembly is axially spaced from the electric assist motor and connected thereto by a connection tube.

  • Patent number: 4479376
    Abstract: A fourslide metal wire and strip forming machine is provided with a removable drive motor mounted on a hinged door; a clutch shaft journalled in a plurality of bearings permitting easy removal and replacement of electric clutch and brake assemblies; a dual-speed drive shaft driven by a shiftable gear train, turning a reversible feed cam providing single and double feed cycles; a positive-action feed mechanism with resilient shock-mounting actuation for the feed carriage gliding on a low-friction ball-and-groove bushing; at least one tool-carrying angle slide cooperating with the conventional four slides converging upon the mandrel; an adjustable kingpost removable from behind the preferably vertical fourslide plane; and a supplemental "electronic handwheel" drive motor connected for reversible incremental actuation in small increments to facilitate tooling and feed assembly set-up operations.

  • Patent number: 4201521
    Abstract: An improved pump and motor assembly includes a fluid pump and an electric motor which are accurately positioned relative to each other by a plurality of locating pins which engage the inner surface of a common housing. By using a single reference surface, that is the inside surface of the housing, the adding of tolerances and the resulting compounding of inaccuracies in locating the pump and motor relative to each other is avoided. The pump has a cheek plate with a bearing surface which rotatably supports one end of the motor armature shaft. The locating pins extend outwardly from a major side surface of the cheek plate into abutting engagement with the inner surface of the housing to locate the cheek plate and the armature shaft bearing surface relative to the housing. A cam or stator ring of the pump is also mounted on the locating pins to accurately position the cam ring relative to the pump rotor and motor armature.

  • Patent number: 4072450
    Abstract: An improved pump assembly includes a pressure plate having inlet and outlet ports for conducting fluid to and from a pumping chamber. The pressure plate includes three layers formed by plate sections having major side surfaces which are bonded together to prevent leakage between the layers. A first one of the plate sections has an outer side surface which is disposed adjacent to the pump rotor. This first plate section is advantageously made of a wear-resistant material to minimize wear upon rotation of the rotor. An intermediate plate section is disposed between the first plate section and a second plate section. The intermediate plate section cooperates with at least one of the two outer plate sections to form a passage which interconnects a pair of ports formed in the pressure plate. In the illustrated embodiment of the invention, the passage is utilized to connect a pair of inlet ports in fluid communication.
