  • Publication number: 20110265716
    Abstract: A powder spray booth (2) with a powder recovery system having an overspray intake (18) communicating with the interior of the booth. A vertically extending duct (20) leads from the overspray intake to a powder recovery system such as, for example, a cyclone. The vertically extending duct may have doors (32) opening to the interior of the booth to provide access to the vertical duct for cleaning. The doors may have holes (120) to aspirate air from the booth interior to optimize air flow patterns within the booth. A diverter plate (26) within the booth (2) defines with the booth floor (10) a floor duct leading to the overspray intake (18). The diverter plate has apertures for allowing oversprayed powder to be collected through the plate.

  • Patent number: 7014556
    Abstract: A powder coating system is provided comprising a powder spray booth (2) with a powder recovery system having an overspray intake (18) communicating with the interior of the booth. A diverter plate (26) may be held within the booth (2) to define with the booth floor (10), a duct leading to an overspray intake (18) of the powder recovery system. The diverter plate may include apertures for allowing oversprayed powder to be collected through the plate. The diverter plate may be provided as two or more diverter plates held at different elevation levels within the booth to define a duct which is larger in parts of the duct which are closer to the overspray intake than parts of the duct which are farther from the overspray intake. Alternatively or additionally, the coating system may include an air assist which provides jets of air across a portion of the interior surface of the booth. The surface may be one or more sloped portions (22) of the floor.

  • Patent number: 6852165
    Abstract: A powder spray apparatus is described including a powder booth with a scraper bar which reciprocates across the floor thereof to collect deposited overspray powder and supply it to intakes located at each end wall. The intakes are connected by a feed channel to one or more cyclone separators. An exhaust duct may also be provided for air-borne overspray powder which preferably forms part of the feed channel. Powder recovered from the cyclone separators may be passed to a common collection hopper by use of a venturi pump which transfers the powder from each separator to the hopper via a sieve located in a ventilated enclosure above the hopper.

  • Patent number: 6728788
    Abstract: A client process resides on a host computer within a distributed data processing system, and the client process requests a remote procedure call for a service procedure. A binding handle of a server process is obtained; a determination is made as to whether the binding handle of the server process points to the client process; and in response to a determination that the binding handle of the server process points to the client process, a positive indication is generated that the service procedure is provided by the client process. In response to a determination that the service procedure is provided by the client process, the service procedure is called using a local procedure call after obtaining a local address for the function within the client process by looking up the service procedure in an interface registry.

  • Patent number: 6366958
    Abstract: A DCE RPC mechanism normally uses a TCP/IP-based transport service to enable client machines to make remote procedure calls to server machines in a distributed computing environment. NETBIOS protocol support for the RPC mechanism is provided by using NETBIOS application names similar to TCP/IP conventions and through use of connection-oriented or connection-less NETBIOS protocol sequences. In particular, NETBIOS names are used as though they include a fixed portion representing a machine, and a dynamic portion representing an application on that machine. New functions are provided to use NETBIOS names in place of TCP/IP addresses and these NETBIOS names are then used via the sockets API, leaving RPC's use of the sockets API unchanged.
