Abstract: A vapor vent for use with an industrial washing machine that increases heat performance of the industrial washing machine by removing vapors from outside two sets of curtain structures rather than in between the curtain structures. The design of the vapor vent is such that vapors and/or steam are extracted from the outer surface of the outer curtain structures proximate the openings of a conveyor type washer without extracting heat from the internal cavity of the housing unit. The vapor vent achieves this by being mounted externally from the vent cowl so as to suction vapors and/or steam that have escaped the outermost curtain, outer curtain structure. This is an improvement upon the old design that withdrew vapors as well as heat from within the machine because the vent is mounted into the vent cowl and has a detrimental effect on the heat performance of the machine.

Abstract: The present invention relates to a wrap around booster (10), and more specifically, the present invention relates to a wrap around booster (10) for use with a high temperature dishwashing machine (40). The wrap around booster (10) heats the water of the dishwashing machine (40) from approximately 110-140° F. to at least 150° F. in the wash tank (11) and at least 180° F. in the rinse tank (26).

Abstract: An electrochemical sensor (A, A′) is specific for the detection of peroxyacetic acid in a solution which also contains hydrogen peroxide. A potential is applied between a reference electrode (120, 120′) and a working electrode (118, 118′). A read voltage (FIG. 7) is selectively pulsed across a counter electrode (122, 122′) and the working electrode. The current flowing between the working electrode and the counter electrode is dependent on the peroxyacetic acid concentration in the solution (FIG. 6). By careful selection of the read voltage, the contribution of hydrogen peroxide to the current flow is virtually negligible. The sensor effectively measures peroxyacetic acid concentrations in the range generally employed in sterilization and disinfection baths (100-3000 ppm.).

Abstract: A cleaning method for CVD apparatus wherein by-products such as SiO2 and Si3N4 adhered to and deposited on surfaces of the inner wall, electrodes and other parts of a reaction chamber at the stage of film formation can be removed efficiently.
