Abstract:
An improved apparatus and process for spray-rinsing chemically treated articles or workpieces with a multi-spray counterflow rinse system wherein the rinsing of chemically treated or otherwise processed workpieces are either supported or suspended by a support carrier which is defined by an article support rack or by a perforated process barrel in which the articles or workpieces are supported therein, and wherein the rack and the barrel include an internal spray assembly that is removably coupled to the rinse tank spray assembly when either the rack or barrel are positioned within the rinse tank, and whereby a fresh uncontaminated rinse solution, preferably fresh water, is pressurized when entering the rinse tank spray assembly. The pressurized fresh water also defines a means to purge the rinse tank spray assembly after completion of each rinse cycle.
Abstract:
A process and apparatus that includes multiple counterflow rinsing of chemically treated, anodized, plated or otherwise processed workpieces, utilizing a single on-line spray-rinse tank or station with successively less concentrated or contaminated rinse solutions that are sequentially pumped from one or more off-line tanks or reservoirs that provide at least three overlapping counterflow spray rinse cycles that cover the treated workpiece or workpieces which can be supported individually or together in a bulk processing barrel in the spray-rinse tank, whereby the workpiece or pieces are decontaminated for any additional processing of a finished part using a minimum amount of water or rinse solution during the rinsing process.
Abstract:
This invention relates to an apparatus that provides, in combination, a multi-spray counterflow rinse system that is interconnected to a plating barrel which includes an internal spray nozzle so as to spray rinse a multiplicity of chemically treated workpieces which are supported within the plating barrel. The plating barrel is rotatably carried by a superstructure from one process station to another so as to be positioned within a single in-line rinse tank that is employed during the steps of an electroplating process. The invention includes two embodiments of a self-aligning coupling device defined by first and second coupling members that are interposed in a rinse-solution supply line. One coupling member is secured to the superstructure and the other coupling member is mounted to the rinse tank, whereby the two coupling members are coupled together as the superstructure and barrel are lowered into the rinse tank for the rinsing process.
Abstract:
An atmospheric evaporator for reducing the water content of various chemical solutions, more particularly useful in the electroplating industry, wherein the evaporator includes a solution-secure molded tank in which a removable blower sleeve is mounted having a blower inlet duct and support strut members formed at the opposite end thereof to support a multiplicity of finned evaporator members over which the solution is sprayed. When a large-volume, low RPM blower is mounted to the inlet duct, a straight-line downdraft of both air and solution is created, allowing the air and evaporated water to exhaust through an up-facing outlet duct, thus defining a substantially "U" shaped duct arrangement from the inlet side to the exhaust side of the tank with the heavy chemical particles returning to the process tank from the bottom of the evaporator tank.
Abstract:
A telephone network voting system is configured to process a large number of calls. The system receives telephone ballots cast by voters by dialing an 8YY telephone number. The telephone ballots are received by network edge switch (NES) from a local exchange carrier (LEC), and sequentially received calls are routed to a repeating sequence of segmentation databases (SDs). The SDs are configured for routing calls in a sequentially received series of 8YY calls to a repeating sequence of said NCPs. Switches are mapped to NCPs to minimize congestion on A and AA links. Call announcements are stored in disk cache.
Abstract:
A source selecting cap and closure for multiple cavity bottles incorporates a first element sealingly engaging a first opening in a first cavity of a bottle and a second opening in a second cavity of the bottle. A second element is movably engaged by the first element and provides an outlet and one or more channels connected to the outlet for selectively communicating with the first cavity of the bottle in a first position and communicating with the second cavity of the bottle in a second position.
Abstract:
This invention relates to a process and apparatus for electroplating that has an electrolyte continually circulating through a rotating plating barrel along with its parts to be plated by having a nozzle spray means with perforation on an elongated perforated tube that is positioned above the center of a barrel, whereby the spray means barrel is provided with recirculated electrolyte by means of a pump recirculating electrolyte from a plating tank to the elongated perforations while the barrel is rotating, so that the parts are agitated and greater speed and efficiency of the plating process can be achieved.
