A pipe-repair tool is disclosed. The pipe-repair tool includes a first chamber to hold a first pressurized sealant and a valve to selectively allow the sealant to flow from the chamber into the interior of a pipe to be repaired. The tool may include a second chamber to hold a second pressurized sealant when using a two-part sealant, in which case the first sealant and the second sealant flow through a mixing chamber when flowing from the first and second chambers to the interior of the pipe. The valve may be a mechanical valve that is opened by moving the tool relative to the pipe to be repaired. The valve may be an electrically controlled valve that is opened with an electrical signal.

A coating material cartridge includes an enclosure, a coating material storage bag received in the enclosure, and a coating material storage bag orientation clip secured within the enclosure. The clip engages a portion of the coating material storage bag to maintain the storage bag in a predetermined fixed orientation within the enclosure during filling of the coating material storage bag with coating material, and also during movement of the coating material cartridge.

The invention is intended for the organization of an automated process for spraying of liquid means of chemical treatment from unmanned vehicles, for example, in precise farming systems. The use of a replaceable, marked and hermetically sealed liquid subsystem in the spray device of the invention, along with an integrated self-diagnosis system, using compressed gas energy and a pressure regulator instead of standard pumps, reduces the weight of the spraying device, improves spraying accuracy, ensures personnel safety and accounting of the accumulated life resource of the main units of spraying devices. All this in combination enables to create fully automated spraying systems.

A hydro-cleaning manual system, in particular apt to the cleaning of a WC, comprising a liquid jet device and a supporting/reservoir device.

Methods and systems for coating with shear and moisture sensitive materials are disclosed. A method of coating a product includes filling an inner bellows chamber of a bellows, which is provided within and isolated from an outer bellows chamber of a tank, with a predetermined amount of the coating material. The method of coating the product further includes supplying a pressurized material to the outer bellows chamber to pressurize the coating material within the inner bellows chamber to an operating pressure, and supplying the coating material within the inner bellows chamber to a spray gun at the operating pressure. The method of coating also includes determining that a measured actual pressure is within a predetermined control range of the target pressure and subsequently coating the product by spraying the product with the coating material from the spray gun.

A variety of dispensing manifolds which are removable connectable to a single deformable container having a single exit portion are disclosed. The dispensing manifolds of the present disclosure provide a single deformable container having a single exit with one or more outlets from which a fluid can be controllably dispensed. The present disclosure also provides a single force generation mechanism, a deformable container holding a fluid or substance, and dispensing mechanisms all on one machine, i.e., a carrier; a system that may also include a pressurized air source that assists a flow of a fluid; and a system that allows for a continuous flow a substance. The systems of the present disclosure provide a deformable container and a method of dispensing wherein, during dispensing, an actuation member is continuously free of contact with the fluid or substance within the container and the actuation member only contacts the exterior surface of the deformable container.

Techniques herein include a bladder-based dispense system using an elongate bladder configured to selectively expand and contract to assist with dispense actions. This dispense system compensates for filter-lag, which often accompanies fluid filtering for microfabrication. This dispense system also provides a high-purity and high precision dispense unit. A modular hydraulic unit houses the elongate bladder and hydraulic fluid in contact with an exterior surface of the bladder. When pressurized process fluid is in the elongate bladder, hydraulic controls can selectively reduce pressure on the bladder to cause expansion, and then selectively increase hydraulic pressure to assist with a dispense action.
