Abstract: Electrical power cable having a reduced surface coefficient of friction and required installation pulling force, and the method of manufacture thereof, in which the central conductor core, with or without a separate insulating layer, is surrounded by a sheath of crosslinked polyethylene. A high viscosity, high molecular weight silicone based pulling lubricant or fatty acid amide pulling lubricant is incorporated by alternate methods with the polyethylene to form a composition from which the outer sheath is extruded, and is effective to reduce the required pulling force on the cable during installation.
Abstract: Provided are apparatuses for the processing of one or more components of a fluid into the surface of a linear substrate. The apparatuses include a processing barrel having a chamber defined therein as well as a linear substrate inlet and a linear substrate outlet. The processing barrel also includes a fluid inlet and a fluid outlet in fluid communication with the chamber. An exposure gap is defined between the linear substrate inlet and the linear substrate outlet. The chamber is dimensionally reconfigurable so that the exposure gap can have a length from zero to greater than zero.

Abstract: A conductor guide system for guiding one or more conductors is disclosed. The conductor guide system can include a first base section and a second base section. A joint can be used to assemble the first base section and the second base section in series. The conductor guide system can further include a roller assembly for holding one or more conductors. The roller assembly, when mounted on one of the first base section or the second base section, holds the one or more conductors off of the one of the first base section or the second base section to which the roller assembly is mounted.
Abstract: The present invention is an electrical junction box comprising a walled enclosure having an articulating cover member. The articulating cover member has an opening and is configured to allow an electrical device such as switch to be coupled to the cover member and further reside within the electrical junction box when the cover member is articulated into a closed position. When the cover member is in an open position, an installer has access to the backside of the electrical device and to the inside of the junction box. The coupling to of the electrical device to the cover member allows for support and stability of the electrical device while installing the required electrical lines that run through the junction box to the electrical device.
Abstract: A system for controlling a flow may be provided. The system may comprise a first flow controller and a gas density meter. The gas density meter may be in fluid communication with the first flow controller. The gas density meter may be configured to calculate a gas density for a first gas flowing through the gas density meter. In addition, the gas density meter may be configured to output a first signal configured to cause the first flow controller to alter a first flow rate of the first gas flowing through the first flow controller. Furthermore, the gas density meter may be configured to output a density signal going to the second controller.
Abstract: A reel chock is disclosed according to various embodiments. The reel chock can include a chock body that has a width that extends along a pivot axis. The reel chock also can include a pivot plate attached to the chock body. The pivot plate can be transverse to the pivot axis. The reel chock also can include a pivot arm that is rotatably connected to the pivot plate such that the pivot arm rotates about the pivot axis. The pivot arm can include a fastener portion that extends at least partially over the chock body.
Abstract: Systems for converting a standard direct current (DC) power from solar panels into a rectified DC power signal for further conversion into alternating current (AC) power are described herein.

Abstract: A molten metal conveyor having a receptor plate in contact with molten metal during transport of the molten metal. The receptor plate extends from an entrance where molten metal enters onto the receptor plate to an exit where molten metal exits the receptor plate. The molten metal conveyor has at least one vibrational energy source which supplies vibrational energy directly to the receptor plate in contact with molten metal. A corresponding method for forming a metal product includes providing molten metal onto a molten conveyor; cooling the molten metal by control of a cooling medium flowing through a cooling passage in the or attached to the conveyor; and coupling vibrational energy directly into a receptor plate in contact with the molten metal on the conveyor.

Abstract: An apparatus for detecting an open neutral condition in a split phase power system is described. The apparatus includes two powered lines providing output electricity to an electrical distribution system and a shared neutral line providing a grounded neutral to the first and second powered lines. The apparatus is configured for detecting when an open neutral condition is present in the split phase power system by determining when a power current is present on one or both of the first and second powered lines while a return current is not present on the neutral line; and in response to detecting that the open neutral condition is present, causing an interrupter to interrupt the power supplied by the first and second powered lines or to generate a signal indicating an open condition.
