Abstract: A coupling assembly and method for retrofitting a water pipe for installation of a pipe insert or device is disclosed. The coupling assembly may include a plunger assembly, a two-part clam shell, an adapter port, and an internally ribbed flexible sleeve including first internal ribs and second internal ribs, wherein the first internal ribs are configured to engage a grooved portion of the adapter port. Prior to installation, a first portion of the internally ribbed flexible sleeve may be attached to the adapter port and a second portion of the sleeve may be rolled up over the first portion. The method may include aligning the port adapter with the cut water pipe; rolling the second portion of the sleeve from the port adapter onto the cut pipe; placing a two-piece clam shell over the sleeve; and tightening two oppositely treaded nuts over the two-piece clam shell.

Abstract: A pneumatically powered snow removing device for removing snow from atop a semitrailer includes a nozzle, which is attached to and which extends angularly from a first end of a first tube. A second tube is attached to and extends angularly from a second end of the first tube. The second tube can be grasped in one or both hands of a user distal from the first tube, enabling the user to position the nozzle above snow on a top of a semitrailer. A first coupler is attached to the second tube distal from the first tube. The first coupler is complementary to and selectively couplable to a second coupler, which is attached to an air hose extending from an air compressor. Air from the air compressor passes through the nozzle to blow the snow from the top of the semitrailer.

Abstract: An adjustable rotary flow valve, comprising: a body; an upstream port; a downstream port; a rotary disc comprising a water flow opening; a rotating mechanism couple with the rotary disc and configured to move the water flow opening past a plurality of channels in a flow of water from the downstream port to the upstream port so as to variably restrict the flow; dial graduations that illustrate a plurality of flow percentage; and a dial couple with the rotating mechanism and configured to illustrate via the dial graduations the current flow percentage based on a position of the rotary disc.

Abstract: An adjustable flow valve, comprising: a body; an upstream port; a downstream port; a body; a side plate; a restricting paddle within the body that pivots into a flow path from the upstream port to the downstream port; a screw coupled with the restricting paddle and configured to swing the restricting paddle from a hinged point across the flow path; and wherein the side plate has an opening that exposes an edge of the restricting paddle and graduations that illustrate a plurality of flow percentage.

Abstract: A printer comprising: a fixed printhead assembly defining a print zone; an input transport assembly for feeding print media along a media path and into the print zone, the input transport assembly being positioned upstream of the print zone; and an exit transport assembly positioned downstream of the print zone for receiving the print media from the print zone. The input transport assembly exerts a higher gripping force on the print media than the exit transport assembly and the exit transport assembly is configured to provide a higher transport speed than the input transport assembly, such that the print media has a degree of slippage relative to the exit transport assembly.

Abstract: Embodiments disclosed herein are directed to a microfluidic refill cartridge having a vent hole and nozzles on a same side of the cartridge. In one or more embodiments, the vent hole and nozzles are located on upper surfaces of the cartridge, such as on a lid that is coupled to a reservoir. In particular, the nozzles and the vent hole may be formed on a microfluidic delivery member that is secured to the lid. A single cover may be used to cover the vent hole and the nozzles. In some embodiments, the single cover may be a flexible material and may adhere to the microfluidic delivery member.
