  • Publication number: 20050000909
    Abstract: Compositions including pellets of alum, a smectite mineral material and optionally sodium or calcium carbonate that can be delivered to a phosphate impoundment located at the bottom of a body of water at the bottom. The pellets of alum, smectite mineral material and optionally sodium or calcium carbonate are dropped through the body of water so that the alum is released when the pellet reaches the bottom of the impoundment thereby treating the phosphates.

  • Patent number: 6699363
    Abstract: A process that can be used for producing a starch product is provided. The process comprises heating a composition, which comprises or consists essentially of a starch, a polyacrylamide, and a multivalent cation. The weight ratio of starch to polyacrylamide is greater than about 2 to 1. The process can also comprise heating a composition, which comprises or consists essentially of a starch and a polyacrylamide to produce a heated composition followed by contacting the heated composition with a multivalent cation. The heating can be carried out at a pH above 7.0 if the polyacrylamide is a cationic polyacrylamide or nonionic polyacrylamide and, if the starch is a cationic starch and the polyacrylamide is an amphoteric polyacrylamide or anionic polyacrylamide, the heating neutralizes less than 75% of the cationic starch.

  • Patent number: 6609778
    Abstract: A method for prevention of nozzle plate peel for inkjet printheads. The nozzle plate is bonded to the nozzle, with a layer of adhesive, and to a support, with a thicker layer of adhesive. This extra support prevents the peeling of the nozzle plate under the forces generated by, for example, a wiper blade passing over it. Spacers between the nozzle plate and support ensure the correct uniformity and constant thickness of the adhesive layer.

  • Patent number: 6422690
    Abstract: A droplet on demand inkjet apparatus utilizing a piezoelectric actuator arranged so as to deflect in shear mode, a method of ink jet printing, and a method of manufacturing an ink jet printing apparatus are disclosed. The apparatus is formed of a plurality of laminated plates arranged so as to define an ink chamber. The actuator forms one side of the chamber and deflects towards a nozzle formed in a nozzle plate which provides the opposite side of the chamber. An interconnect layer acts as the substrate and has orifices to allow the tracks to the drive chip to pass through. On the opposite side of the interconnect layer is the piezoelectric sheet. Electrodes are provided between the interconnect layer and the piezoelectric sheet. The piezoelectric sheet is carved, drilled or molded so as to provide parallel ink channels and a circular depression with a raised central reservation. The piezoelectric sheet is bonded to the interposer plate or ground electrode which in turn is bonded to the nozzle plate.

  • Publication number: 20020008741
    Abstract: An ink jet printhead has a body of PZT bonded to a base plate. Channels cut in the PZT form ink chambers which are actuated by applying voltages to electrodes on surfaces of the chambers. The base plate also carries IC's which contain the drive circuitry for actuating the ink chambers. To ensure reliable electrical interconnection between the chamber electrodes and the IC's, the electrodes and conducting tracks on the base plate are formed in a single step by depositing a conductive layer over both the PZT body and the base plate. The necessary pattern of electrodes and tracks can be achieved by masking or by selective material of conductive material.
