    摘要: A method is described for precisely controlling chlorination of wastewater and chloramination of drinking water. The method involves analyzing the water for the presence of residual monochloramine without interference of dichloramine, organic amines, organic chloramines or nitrites. A color-forming reagent is added to a sample of the water which will develop a colored compound upon reaction with monochloramine, after which the sample may be colorimetrically analyzed to determine the amount of monochloramine present. The method is very accurate and avoids the problems associated with conventional tests used for chlorination control.

    摘要: An automatic necktie neckband tacker, comprising a guage having inner peripheral edges defining an opening substantially equal to the size of a neckband for securing a neckband therein, an upper clamp forming a clamp opening therein substantially equal to the opening of the gauge and aligned therewith, the upper clamp moveably disposed above the guage constituting a clamping unit therewith for clamping therebetween a tie at a neck area thereof adjacent the neckband, and a clamp and cutting blade carrier for clamping and cutting, respectively, an upper needle thread. The upper clamp has a formation for guideably mounting the clamp and cutting blade carrier for movement of the latter upon actuation thereof into a withdrawn position under the upper clamp, as well as into an operative position projecting into the clamp opening. A pneumatic cylinder is operatively mounted on said upper clamp moveably jointly therewith, for actuating the clamp and cutting blade carrier.
