A drain cleaner including a carrier configured to be carried by a user, a cable configured to be inserted into a drain, a drum positioned and rotatable within the carrier, the drum supporting the cable, a motor positioned within the carrier and operable to rotate the drum, and a cable feed control mechanism coupled to the motor to control operation of the motor. The cable feed control mechanism is configured to feed the cable out of the drum and is positioned at a distance from carrier so a length of the cable extends from the drum to the cable feed control mechanism. The cable feed control mechanism is configured to be carried by the user separately from the carrier.

A strip is fastened to an edge of a textile piece by first advancing strip of the ribbon in a direction parallel to the strip of ribbon from a supply. Then a leading end of the strip is gripped a first nip point while advancing additional ribbon from the ribbon supply. The strip is then gripped at a second nip point upstream of the first nip point at a trailing end of the strip. The ribbon is then severed upstream in the strip-travel direction of the second nip point to separate the strip from the ribbon into a sufficient length between the first nip point and the second nip points. The leading or trailing end is then pivoted about at least one pivot axis relative to the other end and positioned near or on the other end, which is then fastened to the edge of the textile piece.

Provided are a systems and methods for continuously providing a metal wire to a welding torch for manufacturing objects by solid freeform fabrication to provide continuous deposition of metal to the freeform object, especially objects made with titanium or titanium alloy wire.

A vehicle-mounted reel utility. A brake wheel is macro-positioned to a non-contact position adjacent to the reel by sliding along a reel-supporting lifting arm. An actuator pivots the brake bracket bringing the wheel into a contact position with the reel. A cable dispenser for figure 8'ing the cable is mounted to the free end of a positioning arm that rotates from a position parallel to a lifting arm to a position perpendicular to the lifting arm. The dispenser is pivotally mounted to the positioning arm, allowing the user to swivel the dispenser about a horizontal arc while maintaining the dispenser in a central lateral position relative to a reel or a vehicle during the swivel movement. A hydraulic circuit controls the dispenser and the actuator that controls the brake wheel from a contact to non-contact position, to coordinate the stopping of cable dispensing.

An extrusion-based production system (300), comprising: a filament roll with a thermoplastic filament (2); at least one assembly with: an entrance (3) for receiving the filament; an exit (4) for delivering the filament, a channel (5) between the entrance and exit; a first and second rotatable component (10, 20), respectively rotatable about a first/second axis (12, 22), and having first/second external ridges (11, 21), wherein, when a filament is introduced into the channel, and the at least one assembly is rotated with respect to the filament (2), the rotatable components rotate about their respective axis, and the axes move about the filament such that the components mainly roll over the filament, and the external ridges (11) penetrate at least partially into the filament (2). A method for feeding a thermoplastic filament.

The present invention relates generally to medical equipment, more particularly, the use of fluid hoses coupling tanks to cannulas, as part of medical gas therapy, such as oxygen therapy. The invention describes a collection system for managing excess flexible hose that a patient might need to wear for medical reasons such as home oxygen medical therapy. It comprises a non-spooling roller system attached to a receptacle for collecting excess hose into the receptacle and extraction from the receptacle, and a power system to power and control the roller system, and design features that optimize the collection and extraction.

A 3D printer includes at least one consumable loading bay configured to supply filament from a consumable supply assembly to a print head and at least one drive assembly that is configured to advance filament to the print head from the consumable supply. Each drive assembly includes a follower wheel rotatable about a follower axis and a drive wheel spaced apart from the follower wheel. The drive wheel is rotatable about a drive axis and is located on an opposing side of a filament path from the follower wheel such that the follower axis and the drive axis are substantially parallel. The drive wheel further includes an outer surface extending between two ends and has at least one engaging portion that is configured to engage with the filament and at least one disengaging portion that is configured to disengage from the filament.
