Abstract: Treatment apparatus has up-stream rollers 2 and down-stream rollers 3. Between the rollers are provided a pair of upper and lower treatment zone plates 4,5, spaced by a gap 6 through which sheet material to be treated can be passed. The plates have grooves 9 occupied by strips defining up- and down-stream even slots 14,15 for flow of treatment liquid into the gap 6. The ends of the upper plate 4 are smoothly rounded at 37. When sheet material is fed into the gap flow occurs on top of the sheet and up over the rounded edge of the plate. Then it flows sideways off the top of the plate without flowing over the top of the upper rollers.

Abstract: Disclosed herein are a washing machine and a control method thereof. The control method effectively transmits high-concentration wash liquid to laundry, while minimizing the amount of water used, through washing using bubbles, and maximizes the increase in volume of the wash liquid rubbed on the inner circumferential surface of the drum using the generation of bubbles and the rotation of the drum to raise the water level of the wash liquid without additional water.

Abstract: A dishwasher comprising at least one partial program step “drying” in which air from a washing container of the dishwasher and/or ambient air is directed through a sorption column with reversibly dehydratable material into the washing container by a fan, and humidity is removed from the air when the same is directed therethrough. The fan is operated at different rotational speeds in accordance with a main controller of the dishwasher in order to influence the adsorption process.

Abstract: Briefly, disclosed is an ultra high pressure blasting head for a mobile marking removal system. The blasting head includes a hydraulic motor that is constructed and arranged for direct connection to a spray bar for controlled rotation thereof. The output shaft of the hydraulic motor is constructed to be hollow or tubular so that the ultra high pressure water can be supplied to the spray bar through the output shaft. The spray head assembly is particularly suited for mobile systems utilized to remove markings and/or coatings from surfaces with high or ultra high pressure liquid.

Abstract: A function for checking whether components of an automatic analyzer properly operate is made available. A pressure sensor is installed in a sample path. A pressure waveform obtained during a washing water discharge operation 10 is used to check the opening/closing of a solenoid valve and the other operations of a dispensing mechanism. This function can also be exercised when a pressure sensor for a conventional sample suction check process is used. Even when the solenoid valve fails to open or close, an alarm is issued to indicate such a failure. This makes it possible to prevent a sample from thinning, thereby providing enhanced data reliability.
