    摘要: A pulse width encoded switching power supply, which may be electrically connected to an electroluminescent (EL) material is described. The power supply exploits both mechanical and electronic resonance principles to provide maximum emission from EL phosphor crystals using an LC tank circuit power supply design at specific frequency to maximize photon emission. Other possible applications are also described.

    摘要: A polyurethane spray nozzle for high pressure abrasive aqueous slurries of limestone and the like. The nozzle is comprised of a hollow body of urethane having a restricted inlet and outlet with internal vanes adjacent the inlet to provide a swirling motion to the slurry. The polyurethane construction is characterized by a high degree of abrasion resistance with a slick surface to inhibit solids build up and a degree of flexibility to inhibit clogging of the vanes by solid pieces of limestone. In a modification the body may be made in a first piece while the vanes may be inserted therein in a second integral piece held together by a ring. An outwardly extending flange which may be reinforced with a metallic member is provided for connection to a pipe line source for the slurry. The flange portion connected to the pipe line source may be constructed of a softer polyurethane than the remainder of the spray nozzle to enhance the flange sealing connection.
