A method (400) for restarting flow in a waxy crude oil transporting pipeline (100), comprising: dividing (402) the gel plug into plurality of smaller gel segments (112, 114, 116) by removing a fraction of gel volume creating plurality of voids (132, 134), introducing (404) a compressible fluid into each of the voids; and applying (406) a pressure at first end (112A) of a first gel segment (112) contiguous to a pumping unit thereby creating a high pressure gradient between first end and second end (112B) of the first gel segment, causing the first gel segment to degrade and move towards a first void (132) thereby compressing the compressible fluid, the movement of the gel segment deforms and breaks the gel segment whereby the broken gel segment migrates towards a next gel segment (114) until all the gel segments are sequentially broken and flow of the waxy crude oil restarts.

An automatic pipe clean system for massage bath equipment includes a bathtub, a water-filling pipe, a water-draining pipe, a suction pipe, a pump pipe, a pump connected between the suction pipe and the pump pipe, an automatic water-filling pipe, a water-filling valve and a controller. The controller is configured to: in a cleaning stage: turn on the pump to allow the water to pass and clean the suction pipe and the pump pipe; and in a drying stage: turn on the pump to allow the water to drain out from the suction pipe and the pump pipe; and turn off the pump.

A reprocessing apparatus for cleaning and/or disinfecting a medical instrument including a fluid container for a reprocessing fluid and a reprocessing device. The reprocessing device includes: a reprocessing space in which the medical instrument is introduced for reprocessing; a fluid line for connection to at least one channel of the medical instrument, wherein the fluid line is configured to transport the reprocessing fluid to the at least one channel; a bubble introducing apparatus for introducing gas bubbles into the fluid line; and a gas bubble speed determining apparatus for determining a speed of the gas bubbles in the fluid line. The gas bubble speed determining apparatus includes a camera for capturing successive images of at least a portion of the gas bubbles in the fluid line.

A cleaning system and process for cleaning a medical system comprising at least one air source at least one cleaning solution source at least one rinsing solution source and at least one switch for switching between the at least one air source, the at least one cleaning solution source, and said at least one rinsing solution source. The process is configured to selectively provide the cleaning solution from the cleaning solution source, selectively provide the rinsing solution source, and selectively providing the air pressure to purge the lines of a medical/dental system.

A coffee machine having a water tank; at least one first pump; at least one first boiler for heating the water; a coffee brewing unit; and circuits to feed hot water and/or steam, with a first outlet for hot water or steam towards an emulsifying device which can be connected to a connection joint of the coffee machine; a second outlet for hot water and/or wash water.

A magnetic duct access door provides for frequent access to a variety of different kinds of duct. The access door allows for an efficient magnetic attraction to a metallic duct and easy manual removal of the access door by tilting the access door via handles on its front surface. The access door includes: an access door base; a plurality of magnets arranged around the periphery of the back surface of the access door base; a compressible sealing member located between the magnetic attachment pads on the back surface of the access door base; at least one handle portion extending from the front surface of the access door base.

An apparatus and method for reprocessing a medical device includes a decontamination basin, a first flush conduit, a second flush conduit, and a manifold. The first and second flush conduits have respective first and second coupling ports configured to fluidly connect to the medical device positioned within the decontamination basin. The manifold is fluidly connected to the first and second flush conduits and configured to distribute the fluid received therein accordingly. The apparatus also includes a first valve, a second valve, and a primary pump configured to discharge the fluid into the manifold at a predetermined supply flow rate. The first and second valve are positioned respectively in the first and second flush conduits for balancing the respective flow rates discharged therefrom at a first predetermined conduit flow rate and a second predetermined conduit flow rate.

An automatic pipe clean system for massage bath equipment includes a bathtub, a water-filling pipe, a water-draining pipe, a suction pipe, a pump pipe, a pump connected between the suction pipe and the pump pipe, an automatic water-filling pipe, a water-filling valve and a controller.
