  • Patent number: 4969916
    Abstract: Flush mountable latches and locks for industrial cabinets, tool carts, electrical equipment enclosures and the like utilize versatile housings of novel configuration together with push-to-operate handles that are pivotally movable relative to the housings to effect unlatching movements of spring-biased, pivotally mounted latch bolts. The lock-type embodiment has a locking mechanism that is mounted on the housing to selectively permit and prevent unlatching movements of its pivotal latch bolt. The resulting arrangement provides sturdy latch and lock assemblies that employ a small number of relatively movable parts that can be assembled, installed and serviced with ease. Improved features include the provision of a plural part handle assembly having portions that are configured to cooperate with a resilient, weather resistant boot that optionally may be interposed between housing and handle assembly components.

  • Patent number: 4934018
    Abstract: Control of a contactless cleaning element (18) in the cleaning line of a vehicle washing system, is accomplished by transmitting at least two energy beams (96, 98) transversely across the vehicle path. When the first beam (96) is interrupted by the passing vehicle, a motor device (64, 66) operates at a normal speed to move the cleaning element away from the vehicle. When the second beam (98) is interrupted, the motor device operates at a higher speed to move the cleaning element away at a faster rate. The cleaning element is pivotally connected by parallel arms (42, 72) to a gantry (12) so that actuation of the motor (64, 66) maintains substantially constant discharge angles relative to the vertical for two spaced apart discharge slots (102, 124) in the cleaning element. The motor (64) is mounted to the gantry 12 by a failsafe slidable carriage assembly (110).

  • Patent number: 4532808
    Abstract: A method and device for ultrasonically inspecting the corner region formed by the joining of a pair of cylindrical conduits is disclosed. Ultrasonic sound beams (62) are transmitted beneath inner surface (12) of the first conduit at an oblique angle resulting in a shallow refracted sound path (74) through the solid corner region (84). Sound energy (76) reflected by the presence of a radially oriented crack (67) within the desired zone of interest (66) passes (80) out of the solid (84) for detection. A device having an ultrasonic transmitter (44) and a directional receiver (60) is disclosed carrying out the inspection method according to the present invention.

  • Patent number: 4526037
    Abstract: The lip of the inner radius of a nozzle mounted through the wall of a nuclear reactor vessel is sandwiched between a transmitter and receiver of ultrasonic sound. The transmitter scans the internal surface of the nozzle lip while maintained a constant average distance from a receiver scanning the nozzle surface on the reactor vessel side of the lip. The two surfaces intersecting to form the inner radius vary in angle as the surfaces are scanned by the transmitter and receiver. Linkage is shown between the transmitter/receiver and the boom with which they are caused to sweep the lip to simultaneously accommodate the saddle shape of the inner radius and the varying angle between the lip surfaces.
