Abstract: A method for folding a polymeric flat bottom bag. The process includes, in general, opening the partially folded bottom of the unfinished bag, pulling the bag bottom taught in the transverse direction, and forming a fin where the two material edges join. A sharp crease is formed between the fin and the base portions of the bag bottom, and the fin is sealed. The fin is creased and sealed while the bag is moving in its transverse direction. The bag's direction is changed, so that the bag is moving in its longitudinal direction, and the fin flaps then folded against the base of the bag bottom. The flaps are sealed to the bottom, resulting in a flat bottom bag. A label may be added to the bottom of the bag.

Abstract: A tubular fitting is threaded at one end for connection to a valve, meter, or the like and at the opposite end to a compression nut. A bore extends through the fitting and includes a tapered or restricted portion. The tapered portion forms an internal shoulder. A compressible sleeve is positioned in the fitting bore opposite the internal shoulder. A reinforcing insert extends through the sleeve. The insert abuts the end of the sleeve. An annular space is provided between the sleeve and the insert for receiving an unthreaded conduit. The insert includes a plurality of annular serrations adapted to frictionally engage the end of the conduit positioned in the annular space. The application of a force on the conduit in a direction to pull the conduit out of the fitting advances the sleeve against the fitting internal shoulder. The sleeve is compressed onto the flexible conduit to increase the frictional engagement of the conduit with the insert serrations.

Abstract: A first clamp member and a second clamp member are positioned in opposed spaced relation with a conduit, pipe or the like, positioned therebetween. Each clamp member has a body portion including an engaging end portion adapted for attachment to a structural support and an opposite connecting end portion. An intermediate portion having an arcuate configuration extends between the engaging and connecting end portions and is adapted to receive and support the conduit. A moisture resistant, polymeric material covers the clamp member body portions so that the clamp members are completely encapsulated to seal out the effects of moisture. A bore extends through the connecting end portion of each clamp member. In assembly, the bores are oppositely aligned to receive a fastening element which draws the connecting end portions together for engagement of the intermediate portions with the periphery of the conduit.

Abstract: A threaded U-bolt receives a conduit to be clamped to an I-beam. A moisture resistant, polymeric material covers the conduit support portion of the U-bolt with the bolt threads remaining exposed. A clamping member covered with a moisture, resistant polymeric coating includes a first end portion adapted to engage a flange of the I-beam and a second end portion adapted to engage the conduit. A pair of apertures extend through the clamping member. A pair of resilient polymeric annular flanges extend upwardly from the upper surface of the clamping member and around the apertures. The U-bolt threaded ends extend upwardly through the apertures. A pair of polymeric nuts engage the threaded ends above the annular flanges of the clamping member. A resilient sealing flange extends radially from the open end of each encapsulated nut.

Abstract: A cable connector includes an insert having a tubular body portion with a conical end portion longitudinally spaced from an annular flanged end portion by diametrically opposed radial grooves. The insert is positioned in an aperture extending through a wall of an electrical junction box. The tubular body portion is contractable to permit the wall surrounding the aperture to be positioned in surrounding relation with the grooves to retain the tubular body portion in the aperture. A passageway extends through the tubular body portion and includes a rectangular inlet and a rectangular outlet. Vertical sidewalls of the passageway diverge outwardly from the inlet to the outlet so that the cross sectional area of the outlet is greater than the cross sectional area of the inlet. A pair of wedge shaped members are positioned in the passageway to secure a cable, such as an insulated conductor, extending through the passageway from being pulled out of the junction box.

Abstract: A molding apparatus for applying a protective coating to an irregularly sized article includes a mold shell having upper and lower portions with mold cavities of a preselected configuration in each portion to receive the article, such as a threaded fitting or coupling, for coating. The shell upper and lower portions are secured together to position the cavities in overlying relation and surrounding the article. Openings extend through the shell portions into the overlying cavities to expose the end portions of the article. Seal members are advanced into the openings and are secured as by threaded engagement to the end portions of the article. The seal members seal the openings and position the article within the cavities to form an annulus surrounding the article as defined by the surface of the cavities. A fluid inlet extends through the shell and into the annulus.
