The inventive concept provides a substrate treating apparatus. The substrate treating apparatus includes a head unit configured to discharge an ink to a substrate; a supply unit configured to supply the ink to the head unit and including a reservoir having an inner space; and a pressure adjusting unit configured to adjust a pressure of the inner space, and wherein the pressure adjusting unit comprises: a first pressure adjusting unit; and a second pressure adjusting unit in which a size for changing a pressure of the inner space per unit time is greater than the first pressure adjusting unit.

An apparatus for personal hygiene of patients with reduced mobility is presented. The apparatus includes a support casing, a housing for accommodating a removable tank, a grippable washing head, a pump, a hydraulic circuit, and a valve assembly. A working operation mode and a standby operation mode are provided. In the working operation mode, the valve assembly determines in the hydraulic circuit a water supply path from the tank, to the pump, to the washing head and finally out of the delivery mouth. In the stand-by operation mode, the valve assembly determines in the hydraulic circuit a water recirculation path from the tank, to the pump, to the washing head and finally back to the tank, without water flowing out of the delivery mouth.

A device for interruption-free coating of can bodies with a coating liquid comprises an inlet container for providing the coating liquid to be applied, a pressurized air source for supplying pressurized air, an application nozzle for spraying the coating liquid with an application pressure onto the container body. An intermediary container is provided, which is connected on the inlet side to the inlet container by means of the inlet pipe and which is connected on the outlet side to the application nozzle by means of an outlet pipe.

A spray gun alignment system precisely aligns a spray gun of a container spray machine for precision application of container coatings. The spray gun alignment system generates a spray gun alignment jig including a container holder adapter and a spray gun adapter. The container holder adapter is inserted into a container holder of the spray machine, and the spray gun adapter is fastened to the spray gun. The spray gun alignment jig is configured to position the spray gun in proper alignment with respect to the container holder.

A liquid delivery device includes a cylinder having a liquid retention section configured to retain a liquid, a piston configured to change a volume of the liquid retention section, a gas container configured to encapsulate a gas at pressure exceeding atmospheric pressure, a regulator which is coupled to the gas container, and is configured to adjust pressure of the gas delivered from the gas container, a gas flow channel having a supply flow channel configured to supply the gas delivered from the regulator to the piston, and a release-to-atmosphere flow channel configured to release the gas delivered from the regulator to an atmosphere, and a three-way valve provided to the gas flow channel to switch between delivering the gas delivered from the regulator to the supply flow channel and delivering the gas to the release-to-atmosphere flow channel.

A system for applying fluid to an agricultural field includes a fluid source, a plurality of nozzles connected in fluid communication with the fluid source, and a plurality of electrically actuated valves configured to control fluid flow through the plurality of nozzles. The plurality of electrically actuated valves are divided into a plurality of groups. The system also includes a plurality of section control valves. Each section control valve is connected in fluid communication between the fluid source and a corresponding one of the groups of electrically actuated valves. Each section control valve is positionable to adjust a flow coefficient of the section control valve. The system further includes a controller configured to control the position of each section control valve to provide a predetermined flow coefficient for each section control valve based on a predetermined fluid pressure for the corresponding group of electrically actuated valves.

A lubric gel composition for personal defense includes a fatty acid at a concentration ranging from 5 wt % to 10 wt % of the composition, a thickening agent at a concentration ranging from 1.75 wt % to 8.75 wt % of the composition, a detergent at a concentration ranging from 1.03 wt % to 4.07 wt % of the composition, a surfactant at a concentration ranging from 2 wt % to 15 wt % of the composition, and water at a concentration ranging from 66 wt % to 90.21 wt % of the composition.

The disclosure relates to a coating agent pump for conveying a coating agent in a coating installation, having a pump inlet, an inlet section, a pump outlet and an outlet section. The coating agent pump according to the disclosure additionally has an outlet-side circulation connection for discharging the coating agent into a circulation line that leads back to a paint supply. Furthermore, the disclosure comprises a corresponding coating installation and an associated operating method.

A dispenser includes: a plunger; a dispensing portion configured to dispense and suction liquid in response to an advance and a retraction of a distal end surface of the plunger along an axial line. The dispensing portion includes: a surrounding portion surrounding the distal end surface of the plunger about the axial line to define an accommodation chamber for accommodate the liquid to be dispensed; and an end portion facing the distal end surface of the plunger. The surrounding portion includes an inlet opening into the accommodation chamber to receive the liquid into the accommodation chamber. A distance from the inlet to the end portion is less than or equal to half of a maximum stroke of the distal end surface of the plunger.
