Abstract: Electrodeposition (ED) systems and methods are disclosed where acid control is possible without adding acid from outside when acid tends to be depleted. A mixture of high neutralizer removal type membrane electrodes and low neutralizer removal type membrane electrodes are placed in an ED tank. To each of these two types of electrodes separate and independent electrolyte circulation systems are connected. To each of these circulation system are connected each correspondingly first and second electrolyte conductivity control means, each of which works to add D.I. water, as a dilution media, to corresponding electrolyte circulation system, when the conductivity exceeds pre-set reference conductivity values. The reference conductivity set point at which value the second electrolyte control means will add D.I. water to the second electrolyte circulation system preferably is set higher than the reference conductivity set point at which value the first electrolyte control means will add D.I.

Abstract: A threshold cover, made of aluminum or similar material, which is retrofit over an existing door threshold by sizing the cover to exactly match the exposed portion of the existing threshold, and then attaching it directly over the threshold. The threshold cover preferably has a non-skid surface, and may have an internal flange of its vertical leg to mechanically interlock with the front edge of the threshold. The cover may be formed in two articulating parts to accommodate non-planar thresholds. Weep channels in the bottom surface cover serve to drain water which may get under the cover.

Abstract: A device for manually turning-on at least one circuit-breaker from the front panel of a cabinet includes at least one sleeve having a front end and a rear end. The sleeve extends through an aperture in the front panel and is movable between a backward position, in which the front end of the sleeve projects slightly from the front panel, and a forward position, in which the front end of the sleeve projects away from the front panel. A spring is compressed to push the sleeve from the forward position to the backward position. A rod is operably connected to the sleeve so as to be displaced following the forward movement of the sleeve and to remain in its position uneffected by the backward movement of the sleeve.

Abstract: An electrodeposition painting cell and method utilizing a membrane electrode cell and membrane monitoring capability is disclosed. In the disclosed cell and method, the article to be painted constitutes the first electrode, and a second electrode is provided by a membrane electrode cell. An electrical current detection device and an electrical potential sensing device provide inputs to a computing device, which computes membrane resistance or membrane voltage drop, with the results thereof utilized to assess membrane degradation. A novel voltage sensing probe and method of use thereof also is disclosed.

Abstract: An electrodeposition coating system widely used for automatic coating process, etc. of motor vehicles. This system includes an article to be coated, which is a first electrode, and provided in an electrodeposition bath and a second electrode or electrodes constituted by one or more electrodes and provided in association with the article. In this system, current is passed between the both electrodes through an aqueous solution of a substance for forming a coating a film, which is contained in the electrodeposition bath, to thereby electrodeposit the substance for forming a coating material onto the article. The aqueous solution and the second electrodes or electrodes are separated from each other by a membrane portion having a first function of precluding the flow of ionized neutralizing agent in the aqueous solution attracted by the second electrode or electrodes and a second function of precluding the flow of ions flowing out of the side of the second electrode or electrodes attracted by the first electrode.

Abstract: A bottle crown cap, particularly for beer bottles, comprising a metal shell and a liner of thermoplastic polyurethane. The liner material is completely reacted, then applied directly to the shell by a hot melt process.
