T-slot interconnects that include a body portion and two orthogonally elongated interlock tabs positioned on opposed sides of the body portion are used for building T-bar structures, including grow-light canopies. In operation, the elongated interlock tabs are placed into T-channels of the T-slot bars and/or T-slot light bars. The T-slot interconnects are then rotated to secure the elongated interlock tabs within the T-channels of the T-slot bars and/or T-slot light bars and, thereby, secure the T-slot bars and/or T-slot light bars together through the T-slot interconnects.

A retaining device configured for retaining at least one medical device adjacent to a supporting surface. The retaining device includes a plate shaped holding portion defining a peripheral edge, a slot extending from the peripheral edge defining a loading channel, and communicating with an internal holding area. The internal holding area is dimensioned to accept the largest medical device the retaining device is configured to be used with. An attachment mechanism is connected to the holding portion to secure the retaining device to a supporting surface. A section of medical device may be inserted into and along the loading channel to enter the holding area and be retained within.

A system for maintaining relative orientation of optical fibers in an array is provided. Fibers extend parallel and include a first fiber and an adjacent fiber. The system includes a fiber holder with alignment holes configured to receive stripped fiber sections. The alignment holes extend from the first surface to the second surface, and the alignment holes include a first alignment hole configured to receive a stripped fiber section of the first fiber and an adjacent alignment hole configured to receive a stripped fiber section of the adjacent fiber. The fiber holder has a wall separating the first alignment hole and the adjacent alignment hole that permits rotation of the stripped fiber section of the adjacent fiber in the adjacent alignment hole without causing rotation of the stripped fiber section of the first fiber in the first alignment hole.

Systems for use in one or more sludge or waste collection devices (e.g., containers, vessels or basins). One such system is a sludge removal system for removing sludge from one or more sludge collection devices. The sludge removal system includes one or more sludge removal grids disposed in one or more sludge collection devices. Each sludge removal grid preferably includes at least one header and a plurality of sludge collection laterals. Another such system includes a fluid distribution system for distributing one or more fluids in one or more sludge or waste collection devices. A movement restricting or prevention member is provided in both the fluid distribution and sludge removal systems to prevent or restrict movement of the sludge collection laterals and the fluid distribution laterals away from or towards a floor of a corresponding collection device without anchoring or fixing the laterals to the floor.

A pipe hanging system for aligned installation of a pipe from a support system without the use of external measuring devices incudes a hanger assembly having one or more hanger members each having a cradle dimensioned to receive at least a portion of the pipe in a supported relation therein. The hanger members include a plurality of alignment marks disposed on and visible along at least a portion of the hanger member to facilitate positioning the hanger member relative to the support members without the use of external measuring devices. A mounting assembly to mount each hanger member to one of the plurality of support members in an aligned orientation, wherein an aligned orientation is at least partially defined by a portion of the cradle disposed a predetermined distance from a preselected portion of the support member onto which the hanger member is mounted.

An apparatus includes a strain relief formed in helical shape and formed with a U-shaped channel. The strain relief can be used around a cable of a component or a spool extension of a fiber tray.

An aluminum wire positioning device system for solar panel cabling and harness string cabling is provided that includes a support structure, a cable, and a wire positioning device. The wire positioning device includes a center leg, an attachment support leg, an attachment member configured to couple the wire positioning device to the solar panel frame or solar panel support structure at an attachment point, a saddle support leg, and a cable support saddle configured to support the at least one cable. The attachment member is arranged at an angle relative to the cable support saddle about the center leg, and a center-of-gravity of the wire positioning device is aligned with the attachment point, the center leg, and the saddle support leg.

A cable hanger assembly comprises a unitary skeletal frame comprising (i) a base that comprises a first base surface and a second base surface that are separated by a channel that is open at a proximate channel end and closed at a distal channel end, (ii) a first sidewall extending from a distal end of the first base surface to the distal channel end, (iii) a second sidewall extending from a distal end of the second base surface to the distal channel end, and (iv) where at least one of the first and second base surfaces includes a slot open on its respective proximate slot end. A removable and replaceable strap or supplemental hanger assembly may be engaged with the slot and hangs from the slot.

A support includes a base and a support structure secured to the base. The support structure is adapted to support a plurality of horizontally extending elongated items. A retainer may be positioned over the elongated items to thereby prevent removal of the elongated items from the support structure. The retainer may be movable to an open position to permit removal of the elongated items.

A method is provided for installing a pipeline on the seabed from a marine pipelaying vessel, including initiation, pipelaying, and abandonment of the pipeline. An embodiment of the abandonment of the pipeline includes halting pipelaying and engaging a hang-off clamp with the pipeline at a position below one or more tensioners, transferring the weight onto the hang-off clamp and holding the seagoing pipeline in the firing line, severing the pipeline, connecting the initiation cable to the lower end of the pipeline held by the one or more tensioners, transferring pipeline tension onto the initiation cable, releasing the one or more tensioners, so that a section of the pipeline is held in the firing line between the pipeline diverter and the initiation cable, vacating the firing line by at least displacing both the pipeline diverter and the initiation cable sheave and thereby displacing said section of the pipeline from the firing line, arranging the A&R cable in the firing line, connecting the A&R cable to the upper end of the seagoing pipeline held in the firing line, releasing the hang-off clamp, and operating the A&R winch and thereby lowering the pipeline onto the seabed.
