Abstract: The invention relates to retention systems and, more particularly, for a modular retention apparatus, system and method for securing and leveling a photovoltaic (PV) panel and other objects on a wall, rooftop and other structure to secure and ground electrically. The photovoltaic panel retention assembly utilizes a solar cap with one or more integral elongated flange extensions of a predetermined dimension to provide spacing between PV solar panels and/or to stabilize the solar cap from tipping under installation forces and load in use. The flanges extend through a support bracket configured with a base portion to support adjacent PV panels in a PV panel array and a base platform portion. The solar cap comprises integral teeth on a surface of the solar cap spaced apart from the flanged projections to locate the teeth adjacent a frame of the PV panel for electrical grounding thereof.

Abstract: An apparatus comprising a clamp with a mounting body having downwardly extending legs with at least one leg configured with an arcuate surface and a slot formed in a bottom surface of said mounting body by the downwardly extending legs for receiving a raised portion of a surface and a top portion for securing the device thereon. The clamp further includes one or more pins being received in one or more push-pin holes formed in the arcuate surface of the mounting body at a predetermined angle relative to said slot, whereby the predetermined angle can secure the clamp to varying designs of the raised portion, and a fastener adapted to be received in a fastener hole formed adjacent the one or more push-pin holes in the arcuate surface to force the one or more pins against the raised portion disposed in said slot and secure the clamp thereto.

Abstract: A clamp assembly that may be used for securing to a raised portion of a surface. The clamp assembly comprising a mounting body of a general block shape having a slot for receiving the raised portion formed in a bottom surface of the mounting body attaching the clamp assembly thereto. The clamp assembly is configured with one or more pins that may be formed in a substantially elongated cylindrical shape. The pins may be configured to be received in one or more push-pin holes formed in the mounting body, whereby the push-pin holes extend to the slot from a side surface of push-pin holes. The clamp assembly includes a fastening element adapted to be received in a fastener hole formed adjacent the push-pin holes in the side surface of the mounting body. The fastening element is configured to secure, attach and hold the clamp assembly to the standing seam by forcing the pins against the raised portion of the surface disposed in the slot.

Abstract: A retention apparatus, system and method for attaching a cross member with an anchor assembly to a latch assembly of a top block and clamp assembly secured to a wall, roof or other structure. The retention system is useful to prevent snow, ice and other objects from sliding off a roof. According to an exemplary embodiment, the retention apparatus and system may be secured to a standing seam on a metal roof to use an ice flag for retaining snow and ice between standing seams. The retention apparatus, system and method comprising a fastener securing a top block with a latch assembly to a clamp assembly attached to the standing seam of the metal roof. An cross member configured with an anchor assembly for operably connecting to the latch assembly of the top block by a ninety degree 90° straight-in approach to the latch assembly formed in the top block.

Abstract: A rotary die head has radially extendable and retractable thread cutting tools moving in paths of different angularity relative to the workpiece to permit one tool to cut a load flank in the workpiece at one lead and another tool simultaneously to cut a stab flank in the workpiece at a different lead, with the tools commonly generating the thread root, whereby a dual lead tapered thread may be formed on the workpiece in one pass. The respective cutting tools may have chasers with multiple teeth to permit the formation of deeper dual lead tapered threads in one pass. The die head may also have a radially extendable and retractable turning tool commonly driven with but moving in opposite directions from the thread cutting tools, whereby the turning tool when extended may form a seal or thread relief surface on the workpiece while the thread cutting tools are retracted.

Abstract: A centering and self-adjusting chuck for clamping stock includes at least three circumferentially spaced dependent jaws that initially are displaced by being simultaneously radially inwardly driven equal distances under low pressure to center the stock positioned therebetween and further includes at least three other circumferentially spaced independent jaws that are then independently displaced by being radially inwardly driven under low pressure any distance required to have each such independent jaw engage the centered stock, the dependent and independent jaws finally being displaced by being simultaneously radially inwardly driven under higher pressure tightly and uniformly to clamp the stock therebetween for subsequent machining.

Abstract: A chip breaker includes an abutment surface having geometry generally corresponding in profile to the geometry on the cutting edge of the associated thread chaser to permit such abutment surface to be uniformly spaced from respective roots and crests of the thread chaser and in close proximity thereto when the chaser and breaker are clampingly juxtaposed. The juxtaposed or trailing surface of the chip breaker has angularly biased, parallel grooves therein to deliver coolant past the chaser body and then into the cutting area along the respective flanks of the chip breaker and chaser geometry.

Abstract: A profiler employing an arm which rocks about a fixed axis and carries a stylus for following a profile to be indicated and recorded. During rocking of the arm from, and return to, a normal starting position, the arm is extended by a cam, and spring returned under the control of the cam, so that the surface engaging edge of the stylus follows a lineal path tangent to the arcuate path which the edge would follow were the arm of constant length. The point of tangency of the lineal path is at the position of the surface engaging edge in the normal starting position of the arm. This adapts the profiler for more accurate indications of profiles, especially in profiles in which departures from the mean are large. A second like arm and stylus are provided and arranged so that the stylus edge follows a lineal path coincident with the same tangent. As a result profiles of opposite faces of an article can be traced by the styli, respectively, simultaneously, at points aligned with each other lengthwise of the tangent.
