  • Patent number: 5006846
    Abstract: Electric power line phase conductor (line) monitoring system in which a single measuring station can measure all the power parameters of voltage and current and phase angle plus ambient and line temperatures. The measuring station fastens to the line, typically draws power from the line, is small, light, and manually installed without the need for a line power outage. The measured data is transmitted from the measuring station up on the power line phase conductor to a ground receiving and data processing station by either radio or a fiber optic cable or an optical-through-air data link. Each type of data link, fiber optic, radio or optical-through-air, can be built to carry either analog (linear) or digital data. Line true RMS voltage and true RMS current values, line phase angle, along with ambient and line temperature values are digitized and transmitted in digital form through a digital data link.

  • Patent number: 4691369
    Abstract: The bag is preferably a flat bottom side gusseted open top bag of the shopping bag type, which has soft braided or woven fabric handles. The handles are closed bail type handles having ends which are sandwiched between the bag side walls and a patch adhesively secured to the inner surface of the bag side walls. The bail portion of each handle is soft, limp and flexible while the end portions of each handle sandwiched between the patch and bag wall are stiff and relatively rigid. The ends of the handles are stiffened prior to assembling the bags. In assembly, the bag body is formed and the patches are adhesively secured to the bag side walls. Non-adhered pockets are positioned between the patches and the bag walls for reception of the stiffened ends of the handles. The ends of the handles are coated with adhesive and then inserted into pockets for securing to the bag body.
