A cylindrical cavity for receiving the tubular article and a metal casing body delimiting a seat substantially inside which the insert is wrapped around the article, the insert having an external projection which extends radially towards the exterior of the insert and is configured to cooperate with a corresponding orifice formed in the seat of the metal body so as to position the insert inside the body, the projection comprising a base attached to the insert and a head provided at the periphery of the head with a protruding clipping edge configured to hold the insert inside the metal casing body. The insert has, at the base of the projection, a through hole extending in line with the clipping edge.

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 support assembly for a heating, ventilation, and/or air conditioning (HVAC) system includes a bracket comprising a base and an arm extending from the base. The arm includes a flange having a plurality of connectors configured to facilitate coupling to a clamp at each of a plurality of positions along the arm. The arm is configured to engage with and support a conduit of the HVAC system via the clamp.

A vibration-isolating insert for a pipe clip is adapted to bear against an inner circumference of a substantially annular pipe clip body and ultimately, in use, to be positioned between the outer circumference of a pipe and the pipe clip body. The vibration-isolating insert includes an elongate strip of vibration-isolating material which has a pipe facing side and a pipe clip facing side. The strip of vibration-isolating material has adjacent either lateral edge thereof a series of discrete exposed hooks of plastics material which is more rigid than the vibration-isolating material. The hooks protrude relative to the pipe clip facing side of the strip of vibration-isolating material.

An anchor for a cable or rod includes a ferrule or other spring stop, to which one or more springs or arms are coupled. The spring stop may be attached to an end or other region of the cable to enable the cable to be tensioned against a support structure. The one or more springs or arms may be, for example, one or more coil springs, one or more conical coil springs, two or more cantilever springs, or one more arms. The anchor is twisted or pushed through a hole in the support structure from a first side to a second side and contacts the surface of the second side. A ferrule spring stop may be swaged to the cable or rod.

A hydropower installation includes a water supply and an energy generating station, with the supply at a higher level than the energy generating station; and a duct extending between the supply and the energy generating station. The energy generating station of the hydropower installation is configured based on high water velocity and low pressure. The duct may comprise plastic pipes. The duct may be arranged on a foam support and enclosed by a foam embedment. The duct may comprise at least two duct sections, with an intermediate energy generating station arranged between the duct sections of the duct. The duct may comprise internally extending protrusions, such as dimples to promote a laminar flow of fluid through the pipe. The duct may taper. Water pressure inside the duct may be maintained at atmospheric level. The proposed features all contribute to a pressure free velocity based system.

An aircraft assembly with first and second seat rails for interlocking with an aircraft seat, and a systems component mounting member interlocked with those seat rails. The mounting member has a first anchor member interlocked with the first seat rail and a second anchor member interlocked with the second seat rail. The assembly includes an aircraft systems component mounted on the mounting member. Existing seat rails or tracks of the aircraft can be used for attachment of support brackets for aircraft systems components. A novel way of using existing seat rails to provide anchorage points for systems brackets for systems components is disclosed.
