Abstract: METHOD AND APPARATUS FOR DETECTING SURFACE FLAWS       IN ELECTRICAL CABLE PLASTIC JACKETING Abstract This invention employs principles associated with air-lubricated thrust bearings, to provide highly sensitive indicators of the presence of defects along the surface of a cable insulative layer. A spring-loaded mounted probe containing anaxial air passage is closely directed at the cable surface. The cable is moved linearly under the probe, and air is introduced to create air flow at and along the surface in the vicinity of the probe's outlet oriface. The static pressure at the probe outlet oriface is essentially constant, until a surface defect such as a scratch or a protrusion causes a substantial change in the air pressure or air flow rate. The change is detected and recognized as an indication of defect.

Abstract: A one-piece, cold-formed rocker arm is disclosed. The rocker arm is of the boat type and includes a one-piece metal body which is cold-formed from a metal blank and is of U-shaped cross-sectional configuration throughout most of its length.      The body has a bottom wall with structurally-integral side walls extending upwardly therefrom in generally parallel relationship. An intermediate, concave portion of the bottom w all has an opening therethrough which receives a fulcrum of a pivot post. One end portion of the rocker arm body has a recess to receive an end of a push rod which imparts pivotal motion to the rocker arm about the fulcrum. The other end of the rocker arm body has a pad for engaging an end of a valve stem to impart motion to the valve stem when the rocker arm is pivoted about the fulcrum. Outwardly-extending stiffening Flanges are formed at upper edge portions of intermediate portions of the side walls, which provides strength and stiffness to the side walls. The flanges substantially eliminate or at least substantially reduce buckling of the side walls during operation of the rocker arm and thereby eliminate or substantially reduce deflection between the two end portions of the rocker arm body.

Abstract: Anodic or cathodic electro-coating of hollow bodies, in particular cans, such as soft drink cans or the like, is done by means of a water soluble lacquer as electrolytic liquid which comes into contact with the cathode (or anode) and which is conducted to the surface of the hollow body that constitutes the anode (or cathode) in at least one uninterrupted stream that forms a conductive connection.  In order to be able to coat a large number of hollow bodies per unit time using a process of this kind, the present invention proposes that the hollow bodies (1) are moved with their openings (3) downwards across an electrically conductive grid (4), while the lacquer is sprayed through the unobstructed intervening spaces between the bars that make up the grid or frame in streams that rise into or over the hollow bodies, so that their whole inside and outside surfaces are covered with an unbroken coating.

Title: Dual system using three electrodes to treat fluid
Inventor: IBBOTT JACK K
IPC: C02F1/48
Filed: 1991-04-25
Abstract: ABSTRACT OF THE DISCLOSURE    The present invention is drawn to a method and apparatus for treating electrically conductive fluid.   Positive and negative electrodes of electrically conductive materials having different electrochemical potentials are spaced apart and electrically isolated from one another so that the only electroconductive connection that develops an electrochemical potential between the electrodes is established by fluid to be treated flowing between the electrodes.  Such fluid is therefore ionized which will both prevent the precipitation of solids from the fluid which would tend to form a scale on the inner surface of piping through which the fluid flows, and aid in the removal of a previously formed scale.  On the other hand, a third electrode is also provided so as to be electroconductivly connected with the positive electrode but electrically isolated from the negative electrode.  Therefore, the third electrode will release metal ions into the fluid.  These ions will inhibit the release of a compound into the fluid having a principal element that is the same as that of the metal ions released by the electrode.  In such a way, the fluid can also be treated to inhibit a particular compound, to which the fluid might be exposed, from dissolving into the fluid.
