Patent number: 5865979Abstract: The entire outer surface of a ground rod, including its pointed end portion, has a continuous and uniform electroplated coating. The rod has a blunt end portion shaped to minimize mushrooming when it is hammered for driving the rod into the ground. Jets of plating solution directed against the rod produce swirling motion of plating solution around the rod while it moves longitudinally through a plating bath. Uniformity of the plated coating may be enhanced by rotating the rod during longitudinal movement through the plating bath.Type: GrantFiled: December 4, 1996Date of Patent: February 2, 1999Assignee: Thomas & Betts CorporationInventors: Albert Lee Collins, Jr., Rick Alan Boyd, Herbert Lester Bradshaw II, Alvin Jerome Huber, Charles Thomas Wessner, Dennis Bowman Ruch

Patent number: 5783790Abstract: A surfactant is added to anodic or cathodic water obtained by electrolyzing deionized water or high-purity water. Then, an object of treatment is treated with the anodic or cathodic water containing the surfactant. The object of treatment may be treated, in this way, while irradiating it with an ultrasonic wave having a frequency between 30 kHz and 3 MHz. Furthermore, the anodic or cathodic water is continuously jetted or dropped onto the object of treatment from a nozzle, while irradiating an ultrasonic wave at least at a part in the feed pipe of the anodic or cathodic water.Type: GrantFiled: December 2, 1996Date of Patent: July 21, 1998Assignees: Organo Corporation, Tadahiro OhmiInventors: Kenichi Mitsumori, Yasuhiko Kasama, Koji Yamanaka, Takashi Imaoka, Tadahiro Ohmi
