An all plastic compression spring assembly includes a slotted tubular spring element formed from a tensile polymer material and upper and lower loading cones received at opposing upper and lower ends of the slotted tubular spring element. The upper loading cone may be axially compressible towards the lower loading cone within the slotted tubular spring element whereby the slotted tubular spring element radially expands in tension to create an opposing radial contraction force, and in turn, an axial extension spring force. When released, the spring element elastically returns to its normal at rest shape, returning the cones to their normal at rest positions. In some dispenser configurations, the lower loading cone may be stationary or fixed within the dispensing head and the upper loading cone may be downwardly compressible toward the lower loading cone by movement of a nozzle head.

A vibration and sound deadening treatment applied to the exterior of downspouts or other gutter pieces which quiets any sound generated when water or other weather contacts the downspout. When placed on the exterior of the downspout, especially near turns in the spout, sound generated by rain and water moving through the downspout is dampened by reducing or removing completely the vibrations generated by the rain and water. This prevents the need to place anything inside of the downspout that may wind up clogging the spout and drain.

An anti-vibration material used in an engine mount is provided to include: a clay mineral; and a solvent, the solvent containing water and a polyhydric alcohol having a molecular weight of 106 or less, wherein the solvent has a polyhydric alcohol content of 35% by mass or more and 55% by mass or less.

An elastic member for a pump assembly is provided. The elastic member may include an upper support; a lower support provided under the upper support; and a connection part which connects the upper support and the lower support, and in which peaks and valleys are repeatedly formed in an outward direction to be bent when the elastic member is pressurized.

An elastomeric isolator is described comprising a layer of an elastomeric material, wherein the layer of elastomeric material is provided with a reinforcing material layer in the form of a graphene layer.

In one embodiment, a fluid dynamics system includes a solenoid valve including a valve body including ports including an inlet and outlet port, and a valve cavity having a direction of elongation and configured to provide fluid connectivity between ones of the ports, a solenoid coil disposed around valve cavity, and a plunger including a permanent magnet, and configured to move back-and-forth along the direction of elongation between a first and a second position in the valve cavity selectively controlling the fluid connectivity between respective ones of the ports, the valve body including shock absorber(s) to soften striking of the plunger against the valve body in the direction of elongation, and a controller configured to apply at least one current to the solenoid coil to selectively move the plunger between the first and second position, and to selectively maintain the plunger in the first position and the second position.

A damping extrusion, preferably made from a thermoplastic vulcanizate (TPV), for use with a clip for piping/tubing/ducting comprises an elongate body having a side wall at, or towards each side, an upper surface that, in use, faces the clip, and a lower surface that, in use, faces the piping/tubing/ducting. The damping extrusion comprises a first protrusion extending from the lower surface at, or towards each side of the elongate body and a second protrusion extending from the lower surface at, or about a centre of the elongate body. An inner wall of at least one of the first protrusions is concave and at least one or both of the side walls of the elongate body has a concave recess.

An electronic device can include a first electronic component, a second electronic component, and an energy dampener positioned between and in contact with the first electronic component and the second electronic component. The energy dampener in this example includes a carbon nanotube-aerogel matrix including carbon nanotubes embedded in an aerogel with a rubber composited therewith.
