Title: Method for continuous molding and apparatus therefore
Inventor: BROWN ROBERT L
IPC: B29C33/30
Filed: 1991-07-12
Granted: 1995-11-28
Abstract: A method and apparatus for a nonsynchronous system for continuously molding articles from a material cured by the control of temperature and pressure.  The apparatus includes a multi-section self-clamping mold, a controller system,  a material injector,  a transfer system, a curing apparatus for curing the articles, and a mold separator-assembler.  The method comprises pre-treating and then assembling the mold in a clamped condition.  Under the control of the controller system, the  mold  is  then  injected  with  material  from  the injector, and moved by the transfer system through the curing apparatus to cure the material within the mold. Once cured, the controller system moves the mold to the mold separator-assembler via the transfer system.  The mold is then disassembled into sections,  the molded article is removed, and the sections are pre-treated and reassembled, for the next injection operation.

Abstract: A process for removing, from spent electroless metal plating bath solutions, accumulated byproducts and counter-ions that have deleterious effects on plating.  The solution, or a portion thereof, is passed through a selected cation exchange resin bed in hydrogen form, the resin selected from strong acid cation exchangers and combinations of intermediate acid cation exchanges with strong acid cation exchanges. Sodium and nickel ions are sorbed in the selected cation exchanger, with little removal of other constituents.  The remaining  solution is subjected to sulfate removal through precipitation of calcium sulfate hemihydrate using, sequentially, CaO and then CaCO3.  Phosphite removal from the solution is accomplished by the addition of MgO to form magnesium phosphite trihydrate.  The washed precipitates of these steps can be safely discarded in nontoxic land fills, or used in various chemical industries.  Finally, any remaining solution can be concentrated, adjusted for pH, and be ready for reuse.  The plating metal can be removed from the exchanger with sulfuric acid or with the filtrate from the magnesium phosphite precipitation forming a sulfate of the plating metal for reuse.  The process is illustrated as applied to processing electroless nickel plating baths.

A power control feedback scheme may also be utilized. At the cell-site communicating with the mobile unit, the mobile unit transmitted pow-er is measured by the received power measurement unit (60) at the cell-site. A command signal is generated at the cell-site and transmit-ted to the mobile unit for further adjusting mobile unit transmitter power corresponding to deviations in the cell-site received signal pow-er. The feedback scheme is used to further adjust the mobile unit transmitter power so that mobile unit transmitted signals arrive at the cell-site at a desired power level.

Abstract: An apparatus for compressing and containing a material in an elastomeric net (26). The apparatus comprises a compression chamber (12), a material compressor (16), a holding chamber (18), a net expansion and placement mechanism (42), and a bale advance mechanism (20). The material compressor is coupled to the compression chamber to compress a selected amount of the fibrous material in a direction transverse to the general lay of the material within the compression chamber to form a compacted bale (10). The holding chamber has an outlet and an inlet coupled to the compression chamber. The holding chamber also has an axis defined by a line extending between the center of the inlet to the center of the outlet. The net expansion and placement mechanism is for receiving the net, stretching the net to obtain a cross-sectional shape that is slightly larger than that of the holding chamber, and placing the net over the holding chamber with one end of the net slightly extending beyond the outlet. The bale advance mechanism is coupled to the holding chamber and compression chamber. Its function is to advance the bale from the compression chamber to the holding chamber and through the holding chamber outlet such that the bale contacts the end of the net that extends beyond the outlet and pulls the net onto the bale when the bale advances through the outlet.

Title: Ph measuring system
Inventor: SETTLER BERT
IPC: G01N27/403
Filed: 1995-06-12
Granted: 1999-09-14
Abstract: A pH measuring electrode includes a probe having two lumens with adjacent first ends. An exposed sensor electrode is secured to the end of one of the lumens. A conductor leads through the first lumen from the sensor electrode for connection to a meter for indicating pH. An electrical reference, for example a fibrous thread extends along the second lumen and is electrically connected to the meter. A porous plug closes the end of the second lumen adjacent the sensor electrode and is electrically connected to the thread. When the thread is saturated with an electrolyte it acts as a salt bridge that can be connected to a reference half cell in the system. The close spacing of the bridge and the sensor electrode is desirable to ensure a quick response and to minimize drift. A chamber may be secured to the tube, with the reference thread extending into the chamber. For use, the chamber and the thread carrying lumen are filled with an electrolytic gel. To provide adequate shelf life, this gel may be injected shortly before use through an access port provided in the chamber for that purpose.
