A mechanism for securing multiple apparatus to a drain cleaning machine is described. The mechanism includes a bracket arranged on a frame of the drain cleaning machine. The bracket allows a drum and a feed mechanism to be removably secured to the frame. The bracket includes a base and pivotable latch. A drum bearing from the drum can be secured between the base and the latch when the latch is in a closed position. Mounting pins from the feed mechanism can be inserted into two bores in the bracket, and secured therein by plunger pins. One plunger pin is manually operated, to selectively lock the latch in the closed position, and to selectively secure one of the mounting pins in one of the bores. Another plunger pin is operated by pivoting of the latch, and functions to selectively secure the other mounting pin in the other bore.

A self-adjusting microbot pigging system for cleaning the interior of a pipe, the system comprises a plurality of microbots, each microbots comprises a propulsion device and a programmable computer processor operatively associated with the propulsion device, each of said processors programmed to instruct its associated propulsion device to operate in cooperation with one or more of the other microbot propulsion devices of said plurality of microbots to form a pig in the pipe.

A bore guide for cleaning a firearm has an elongated body defining a bore configured to receive a cleaning rod and brush, the elongated body having a forward end configured to be received in a chamber of the barrel and having a forward aperture to transmit the brush to the barrel bore, the elongated body having a rear end opposite the forward end and defining a rear aperture, a stop adjustably connected to an intermediate portion of the elongated body and movable over a range of different positions along the length of the elongated body, and the stop being adjustable to generate a rearward force against a portion of the firearm, and a forward force by the forward end of the elongated body against the chamber. The elongated body may be externally threaded, and the stop may engage the threads. The stop may extend laterally from the elongated body.

The present invention relates to a device for cleaning and/or disinfecting surfaces, particularly for cleaning inner surfaces of the toilet bowl. The device comprises an elongated housing connected to a bottle with the cleaning and/or a disinfecting liquid, and a pumping mechanism for pressurizing said liquid composition, and at least one nozzle for the output of said liquid composition, wherein the nozzle is in fluid communication through a conduit of the device with said pumping mechanism. The pumping mechanism is provided at one side of said housing and said at least one nozzle is provided at the opposite side of the housing.

A cleaning implement for a firearm comprises a rigid, axially extending, support adapted for connection to the end of a cleaning rod or other manipulating implement. Axially spaced, resilient panels are integrally molded onto a hub through which the support extends. A barb at an end of the support is provided to secure a cleaning patch that is wrapped around the outer edges of the panels and maintained in contact with an interior surface of the firearm during cleaning by the resilience of the panels.

An air fed mycoplasma device includes an array of elongate microchannels formed in a plastic or ceramic having tolerance to ozone and other radicals formed when plasma is generated from air in the microchannels. The microchannels include inlets configured to accept an air feed, and outlets configured to direct plasma jets toward a surface (which may be flat or internal to a pipe, for example) or object. An array of electrodes within the plastic/ceramic housing is configured to ignite and maintain plasma in the microchannels and is isolated by the dielectric from the microchannels. A supply intake for is configured to providing a plasma medium into the microchannels.

A uniform oleophobic or oleo- and hydrophobic film is applied to equipment used in the petroleum industry. The methods can be applied to new equipment or equipment pulled from service, with the application process being performed in a controlled environment or the field. Applicator tools for efficient delivery and application of cleaners, solvents, and films used in the coating process are also described.

A pipe cleaning assembly has a connection fixture having a body defining a cavity. A first aperture, opposing first auxiliary aperture coaxially aligned with the first aperture, second aperture, and opposing second auxiliary aperture coaxially aligned with the second aperture are in fluid communication with the cavity. A first connection flange extends from and surrounds the first aperture, a second connection flange extends from and surrounds the second aperture, a third connection flange extends from and surrounds the first auxiliary aperture, and a fourth connection flange extends from and surrounds the second auxiliary aperture. A bonnet is inserted through the second auxiliary aperture and is positioned within the cavity of the body and includes a generally cylindrical wall and a plurality of openings formed through the cylindrical wall to direct fluid flowing through the connection fixture.
