摘要： A sand transport detector which detects the discrete impingements of sand particles on an elongated probe member inserted into the sand. A piezoelectric transducer element is cemented to the probe and produces an output signal when impingement occurs. With an electronic circuit coupled to the transducer, an indication of sand transport may be obtained.

摘要： A vane type fluid power machine wherein each vane has a cyclically varying rotational velocity, whereby the compartments formed between adjacent vanes are caused to sequentially expand and contract to produce pump or motor action. Cyclical vane speed changes are produced by unique crank-rotor assemblies associated with each vane unit.

摘要： My invention represents an improvement over the prior art show identified in providing a combination of elements which interact in a novel way to exert a positive force to keep the boat cover taut without yielding under the rain or snow load as will happen in the Burns covers 2,390,986 and 2,474,031 as well as Wright 3,106,218. The structure of my device is provided with two end supports, one for contacting the boat floor and the other for bearing against the under side of the boat cover each support has a knurled or roughened end portion which acts as an anti-skid surface to assist the support in remaining in its installed erect condition.My support device can be easily manually rotated about the central portion to extend its length and assure positive engagement with the cover and boat floor.

摘要： An organic thermoplastic resin having dielectric properties is bonded to a substrate material by heating the plastic, bringing it into contact with the substrate, and applying an electric potential therethrough so as to join the plastic and the substrate together. The substrate material may be an electrical conductor such as a metal sheet or foil, or it may be a plastic of similar or dissimilar chemical composition or a glass or other dielectric.
