  • Patent number: 11428671
    Abstract: An arrangement for non-destructive testing of a component part, which may include a first end surface and a second opposite end surface. The arrangement may include a plurality of discrete piezoelectric transduction elements arranged in a circular array on the first end surface, and an electric wave signal transmitting and receiving unit electrically coupled to the piezoelectric transduction elements. The electric wave signal transmitting and receiving unit may be able to generate an electric excitation wave signal and to receive an electric response wave signal. The piezoelectric transduction elements may deform, upon an application of the electric excitation wave signal, in an in-phase shearing motion parallel to the first end surface and in respective tangential direction with respect to the circular array so as to generate a corresponding structure-borne wave in the component part at the first end surface such that said structure-borne wave can propagate in the component part.

  • Patent number: 5921604
    Abstract: A hydraulic system for opening and/or closing the rear lift gate of a vehicle uses a double or single acting gas charged hydraulic cylinder. If double acting, a second piston separates the head side of the cylinder into hydraulic and gas chambers. A unidirectional (for the single acting cylinder) or a bidirectional (for the double acting cylinder) drives a pump to operate the cylinder. A solenoid actuated on-off valve selectively communicates the ports of the cylinder with tank pressure. A gas charge accumulator may also be provided. In the double acting embodiment, a two way ball shuttle valve which is vented in the center provides alternating communication between the two cylinder ports.

  • Patent number: 5467596
    Abstract: A self-contained rotary actuator assembly has a pump assembly, a precharged hydraulic circuit, and a rotary vane actuator in a single unit. The pump assembly is a bi-directional electric motor driven gerotor pump which is manifolded to a module assembly in which the control elements of the hydraulic circuit are housed. Upon the application of the pressure for driving the rotary actuator in either direction, a pilot operated hydraulic valve is shifted so as to communicate the rotary actuator with the pump. After the pump is turned off, an orifice for the pilot chamber of the valve bleeds the pilot chamber slowly so as to provide a delay in which the rotary actuator holds the convertible top extended or retracted to give the vehicle operator time to latch the top in its closed or open position. In addition, a gas charged precharge chamber in the hydraulic circuit maintains a precharge through a broad range of temperatures.
