  • Electroplating bath and method
    Patent number: 4436595
    Abstract: There is provided an improved gold alloy electroplating bath comprising glycolic acid, an alkali metal salt of glycolic acid, gold and an alloying metal plus a chelating agent capable of forming a stable complex with metal impurities, particularly nickel. The chelating agent, the complexes formed and the decomposition products of the chelating agent are substantially innocuous to the functioning of the bath and to the quality of a deposit from the bath. Nitrilotriacetic acid is the preferred chelating agent.

  • Top dressed plating surface with resilient underpad
    Patent number: 4389435
    Abstract: A playing surface for athletic games comprising a stable subsurface, a resilient underpad of specified character, a pile fabric resembling grass and a sand top dressing. The inventive surface is particularly suited for use as a golf green which properly facilitates control of an approach shot and also provides a true putting surface. The playing surface simulates the feel and appearance of natural turf, but has much greater durability and requires less maintenance. By appropriately varying the construction of the surface, it is possible to control its character to provide for a desired type of play.

  • Surface alloying apparatus including safety circuit
    Patent number: 4205211
    Abstract: An improved apparatus for alloying a surface of a workpiece of the type in which an electrode, formed of the alloying material, is connected to a pulse generating machine which creates repetitive spark discharges between the electrode and the workpiece when the electrode is in engagement with the workpiece, the improvement being a safety circuit which prevents energization of the electrode until it is engaged with the workpiece.
