Abstract: A cable seal includes a heat-shrinkable tubing coupled to a cable outer jacket. An elastic member is positioned about the heat-shrinkable tubing. A cap is positioned about the heat-shrinkable tubing. At least one of the elastic member and the cap has a vertical sealing surface and a horizontal sealing surface. The vertical sealing surface extends substantially coaxially with respect to a longitudinal axis of the cable seal, and the horizontal sealing surface extends substantially radially with respect to the cable seal longitudinal axis.

Abstract: A method of sealing a cable penetration includes assembling a cable seal and inserting the cable seal into a cable penetration. Assembling the cable seal includes adhering at least a portion of a heat-shrinkable tubing to at least a portion of a cable outer jacket, and positioning a secondary elastic seal over the heat-shrinkable tubing. An example of a secondary elastic seal could be O-rings. A cap or other means provides the outer sealing surface.

Abstract: A method for assembling an eddy current inspection device includes at least partially positioning a first tip assembly within a cavity defined by a proximity probe case. The first tip assembly defines a bore therethrough. The first tip assembly is sealingly coupling to the proximity probe case. A second tip assembly is at least partially positioned within the cavity and sealingly coupled to the first tip assembly.

Abstract: A drip irrigation tube formed by longitudinally folding an elongated web having thick marginal side portions, and overlapping and sealing the thick marginal sides to form a tube. Discrete emitter elements are disposed at spaced intervals along the web and are formed by embossing or otherwise forming recessed emission grooves in one of the thick marginal edges so as to form a flow path from the inside of the tube to the outside. The emitter elements operate to provide a constant flow rate over a wide range of working pressures by controlled deformation and constriction of size of relatively short emitter passageways formed by a portion of the emission grooves.

Abstract: A constant drive nozzle for use in combination with an impulse or impact drive sprinkler includes a tubular nozzle body with a drive orifice and a range orifice formed in its outlet end. The stream issuing from the nozzle is formed into a drive stream portion and a range stream portion by the drive and range orifices. Since only the drive stream portion intercepts the drive spoon of the arm which impacts and rotates the sprinkler body, various diameter range orifices can be used in conjunction with a single diameter drive orifice without affecting the rotational speed of the sprinkler body.

Abstract: A reaction drive sprinkler including an improved drive nozzle assembly for rotating the sprinkler in steps about a water supply standpipe. The drive nozzle assembly comprises a fixed drive nozzle through which an inclined stream of irrigation water is projected for passage through a diverter tube mounted in front of the drive nozzle for movement between forward- and reverse-drive positions. The diverter tube is shifted between the forward- and reverse-drive positions by a spring-loaded, over-center reversing mechanism for slightly diverting the water stream for alternated interruption by a pair of laterally oppositely angled deflector spoons on a pivoting reaction drive arm.
