Abstract: A pipe elbow is provided having two parts, each part having an arcuate segment and a linking member for connecting to a run of standard pipe. The arcuate segment of the first part fits into the arcuate segment of the second part. By severing a portion of the arcuate segment of the first part at an angle needed for a specific run of pipe and inserting it into the arcuate segment of the second part, the assembled elbow will conform to the required angle. In addition, the arcuate segment of the first part has an inner aspect which is provided with an extended curved region which extends to the collar. The second part is provided with a lip which fits conformingly with the extended curved region of the first part in order to meet industry standards for minimum overlap of mating parts, even at very obtuse angles.

Abstract: A pipe angle measuring tool and pipe angle marking tool are defined. A template is also defined which is a flexible substrate, such as paperboard, on which images of the tools are printed. A user may create the tools by cutting them out of the paperboard with ordinary scissors or by separating lines of weakness provided in the substrate. The tools are useful in measuring an angle between two pipes and marking the angle on a part of a selectable angle pipe elbow. The template is inexpensive to produce and can, therefore, be provided to purchasers of selectable angle pipe elbows at little or no charge to the purchaser.

Abstract: A mold for use in an injection mold assembly. The mold includes a cast mold member or housing with an internal cooling chamber. The cooling chamber has at least one mold wall with a first surface on one side of the wall and a second surface on the opposite side of the wall from the first surface. The wall has a substantially uniform wall thickness. A central plug is located inside the cooling chamber and is spaced apart from the second side of the wall. A channel is located between the wall and the central plug. The channel extends sustantially from one end to the other end of the cooling chamber. Inlet and outlet conduits are formed in one end of the cooling chamber for channeling fluid into and out of the cooling chamber.

Abstract: A base cover for a utility pole comprises a first base member and a second base member secured to one another to form a base unit to fit round the utility pole. The base unit has an opening at its upper end, the opening adapted to fit closely around the utility pole. A resilient gasket is formed adjacent the opening and is adapted to engage the pole and resist forced movement of the base unit up the pole. The gasket consists of two gasket members, one secured to each base member. The gasket member is a ring with a trunco-conical inner opening. The opening is narrowest at the top. The shape of the gasket allows sliding of the base unit down the utility pole, but resists sliding up the pole. The base unit is assembled at a convenient position along the pole, and slid down to its in-use position at ground level. The gasket prevents it from being lifted out of position without dismantling the two base members.

Abstract: A pipe elbow is provided having two parts, each part having an arcuate segment. The arcuate segment of the first part fits sealably into the arcuate segment of the second part. By severing a portion of the arcuate segment of the first part at an angle needed for a specific run of pipe and inserting it into the arcuate segment of the second part, the assembled elbow will conform to the required angle. In addition, a sloped shoulder on the outside of the first part fits in close proximity to the end of the second part to ensure a extension of the first part into the second part in order to meet industry standards for minimum overlap of mating parts. An angled end on the arcuate segment of the second part may also be provided.
