摘要:
The invention provides a method and apparatus for removing a blockage from a fluid conduit. An apparatus comprises a first portion containing a fluid volume separated from the fluid conduit via a controllable valve. The valve is cyclically opened and closed such that a pressure differential between the first portion and the fluid conduit causes a series of pressure pulses in the fluid conduit. The pressure differential is regulated to control the amplitude of the pressure pulses of the series.

摘要:
A cleaning apparatus for microsurgical instruments has a flush chamber closed off at one end by a first plug adapted to liquid-tightly grip one end of the instrument, allowing a portion of the instrument to extend past the first plug and out of the flush chamber. The other end of the flush chamber is closed off by a second plug having an inlet port. Liquid injected through the inlet port on the second plug passes through an internal passageway formed in the instrument and exits the instrument through the portion that extends past the first plug. In another embodiment the instrument has an internal passageway and an end cap through which flushing ports are formed which communicate with the passageway. A first plug having an inlet port is liquid- tightly attached to the end cap and liquid injected into the first plug passes through the plug, through the flushing ports and through the passageway to clean detritus from the instrument.
摘要:
A method and system for cleaning and coating the interior surface (24) of a small diameter piping system (10) is provided. The method provides for cleaning the interior surfaces (24) of the piping system (24) to remove the scale or corrosion build-up (22) therein and the application of a coating (48) to prevent ongoing reaction between the material being conducted and the interior walls (24) of the piping system (10). The method provides for removing the fixtures (20) from all of the piping termination points, cleaning the piping (10) and coating the interior surfaces (24) of the piping with a non- toxic resin (38).

The invention is related to a washing apparatus for cleaning milking related equipment comprising a washing apparatus connectable to an automatic milking station (2) by interconnecting pipelines in such a way as to enable the washing apparatus to circulate a washing fluid through the milking related equipment of the automatic milking station (2). The washing apparatus (6, 7) comprise a circulation tank 6 and a separate pre-filling tank (7), whereby filling in advance and holding of the washing fluid to be used in a subsequent washing step is enabled. The washing apparatus (6, 7) further comprises connecting means for connection of the pre-filling tank (7) to the circulation tank (6). By means of the invention the time needed to complete a cleaning procedure is shortened essentially, and a cleaning procedure rendered more effective. The invention further relates to such method.
摘要:
A method is described for inhibiting a deflagration within a vacuum pump. The method comprises the step of supplying to the pump during operation thereof a reactant for chemically reacting with solid material that has accumulated within the pump during said operation and which can cause a deflagration upon exposure to the atmosphere.
