Abstract: An adjustable tool is provided which includes a selectively positionable and lockable handle. The tool includes a main housing having a handle shaft axially directed transversely of the housing and a handle being rotatably mounted to the handle shaft for selective rotational movement about the handle shaft. The handle shaft has a threaded portion and threadedly advanceable thumbwheel at one end and a handle retaining pad at an opposite end. The handle is interposed between the thumbwheel and the retaining pad for compressive retention between them. The retaining pad includes a locking member comprising a protrusion for nesting reception in a locking member receiving port of the handle whereby upon advancement of the thumbwheel the handle is compressively retained between the thumbwheel and the retaining pad and the locking member protrusion is received in the receiving ports for locking the handle in a selected position relative to the main housing.

Abstract: The electrogasdynamic coating system includes an electrogasdynamic gun for charging material particles indirectly. The gun has a gas inlet which receives from a gas source a pressurized gas in which an condensable vapor is entrained. Corona and attractor electrodes are disposed in communication with the gas inlet for ionizing the ionizable vapor. A dielectric tube extends from the electrodes downstream to a mixing chamber. A first fluid material inlet is connected with a first source of powder or liquid material and a second fluid material inlet is connected with a second source of powder or liquid material. The first and second fluid material inlets are connected with the mixing chamber such that particles of the first and second fluid materials are mixed with the gas and vapor. The vapor condenses and coats the particles during mixing causing them to become charged. In use, a condensable vapor is entrained into a gas flow, the gas flow is passed across corona and attractor electrodes to ionize the vapor.

Abstract: This invention is directed to a novel water soluble conductive material which is capable of being polymerized by actinic radiation. More specifically, this invention involves the use of a radiation curable quaternary ammonium salt obtained by mixing at least one tertiary amine having acryloyl or methacryloyl unsaturation and at least one halide. When the water-soluble conductive material is subjected to actinic radiation sufficient to cause polymerization, it maintains its conductive character, but becomes essentially impervious to attack by water or solvent, and remains tack-free even at high relative humidity. When the water-soluble conductive material is polymerized by actinic radiation, it is not necessary to drive water off during cure and then rehumidify to obtain proper conductivity as is often necessary with the prior art coatings.
