A device for inoculating fluid conducted through pipes includes a reservoir configured to hold an inoculant. The reservoir includes an outlet through which the inoculant is feedable to at least one of the pipes and an inlet configured to route compressed air into an interior of the reservoir. A capillary can be used to conduct the inoculant during inoculation. A flushing device can be provided to flush the pipes. A shared device for generating and/or storing compressed air can supply compressed air for inoculating the fluid and/or flushing the pipes.

There is provided a film forming apparatus including gas supply paths, retaining units, valves, a purge gas supply unit and a control unit. The control unit is configured to implements a film forming process for sequentially performing operations of actuating the valves such that reaction gases are retained in the retaining units, the internal pressures of the retaining units are increased and then the reaction gases are supplied from the retaining units into the process chamber, and a purging process for subsequently repeating, a plurality number of times, operations of actuating the valves such that the purge gas is retained in the retaining units, the internal pressures of the retaining units are increased to a pressure higher than the internal pressures of the retaining units which is increased in the film forming process, and then the purge gas is supplied from the retaining units into the process chamber.

A rinsing line for discharging a rinsing fluid out of a medical technical functional device having been rinsed by means of the rinsing fluid is described, in which the rinsing line is, on the one side, connected, provided or intended for being connected with a section of the medical technical functional device and in which the rinsing line is, on the other side, connected with, provided or intended for being connected with a fluid supplying device for supplying a medical fluid into the medical technical functional device. A medical technical functional device, a medical technical treatment apparatus, a method and a control unit are also described.

A system for cleaning a dairy animal milker unit and applying dip to a dairy animal, the system includes a main control, an air supply, a water supply, a backflush fluid supply, a dip supply, a stall control for receiving the air, water, backflush fluid and dip supplies, and a safety valve that is adjacent to a downstream portion of the milker unit to control backflush and dip fluids being fed to the milker unit.

This application discloses novel vacuum break devices useful in automatic vacuum flushing systems. The vacuum break devices are capable of rapidly breaking the vacuum in a storage tank of a sewer line, thus enabling efficient flushing of sediments and cleaning of the sewer system. The invention also provides automatic vacuum flushing systems comprising these novel rapid vacuum break devices and methods thereof for sewer or storage tank sediment cleaning in urban drainage systems.

A system for cleaning a dairy animal milker unit and applying dip to a dairy animal, the system includes a main control, an air supply, a water supply, a backflush fluid supply, a dip supply, a stall control for receiving the air, water, backflush fluid and dip supplies, and a safety valve that is adjacent to a downstream portion of the milker unit to control backflush and dip fluids being fed to the milker unit.

Herein is a coupler and a clean connection device having the same, which can automate a series of operations for connecting and disconnecting a male coupler to and from a female coupler, clean and dry a wetted portion, drain residual liquid of chemicals together with cleaning water without external leakage in safety when the coupler is separated, and clean and dry the wetted surface before connection and after separation, thereby enabling a clean connection.
