  • Publication number: 20200256754
    Abstract: A sealing device is provided for use with a fitting. The fitting has circular port and a flow path with a longitudinal axis. A circular port encircles a portion of the flow path opposite the port with the sealing device inserted into the port. The sealing device has a circular top with two opposing surfaces depending therefrom but inclined so the surfaces are closer at the top. A continuous sidewall joins the periphery of the two surfaces. The opposing surfaces are inclined and spaced apart further at the top than at an end opposite the top. A cylindrical hole through the opposing surfaces encircles the flow path during use.

  • Patent number: 10656042
    Abstract: A pipeline pressure testing assembly has a fitting defining a flow path and having a port on a wall of the fitting into which a pressure testing device is removably inserted along a central axis of the port for pressure testing. The port is circular, larger than the interior diameter of the pipeline and located at or above the tube forming the flow path through the fitting. The fitting has a recess encircling at least part of the flow path and opening to the port to receive the testing and sealing devices. The recess is formed by two opposing walls inclined relative to the central axis of the recess. The recess walls at the top of the flow path by the port are spaced apart a distance as large as the pipe diameter for cleanout and inspection. A tubular valve stem screws into the testing device and has a rotary valve blocking flow through the tubular valve stem. Flow through the fitting is blocked with the rotary valve closed and the tubular valve stem in a first position.

  • Patent number: 10639729
    Abstract: An apparatus for cutting a window covering comprises a saw for cutting the window blind. A clamp assembly moves the window covering relative to the saw. A controller moves the clamp assembly to automatically position an end of the window covering relative to the saw. The saw is moved into engagement with the window covering to cut the window covering. A dust collection system comprises a shroud substantially surrounds the bottom of the saw blade where the shroud is connected to a vortex dust collector.

  • Publication number: 20190257082
    Abstract: An improved cap and assembly is provided for a poured concrete deck. The improved assembly has a diaphragm seal over-molded to a top plate having a depending sidewall that is snap-fit to a base containing a fire ring. A tubular sleeve is connected to the over-molded top plate by snap fit connections to the sidewall and by threaded fasteners passing through sockets in the sleeve, sidewall and base. The over-molded diaphragm has a funnel shape. A first sleeve cap has depending positioning tabs that may be broken off to adjust the cap height relative to the sleeve, with an inwardly extending latching surface engaging the sleeve when the tabs are removed. A second cap has inwardly extending tabs that fit into channels on the sleeve fit between ridges on the sleeve when rotated to adjustably position the second cap on the sleeve.

  • Patent number: 10344472
    Abstract: A tubular passage for poured concrete decks has an intumescent tube held in a two-part, clamshell base by a bottom clip. A first tube engages the base's top to clamp a funnel shaped, diaphragm seal to the base. The first tube has spaced, radially extending, parallel ridges at predetermined distances from the base. Longitudinal channels separate the ridges. An extension tube has inward extending lugs passing along the channels to engage various ridges when rotated to fix the passage length. The extension engages the base bottom for corrugated deck supports. A cap with repositionable, locating filaments closes either tube.

  • Publication number: 20180231146
    Abstract: A bracket holds a rigid or flexible tube during the pouring of a concrete slab. The bracket has a base and a housing connected to the base. The tube curves around a first tube support on the housing before passing through an opening in the bottom of the housing. The tube and any members inside the tube are cut off so they end inside the housing and are then covered by a housing cap. The base is fastened to a form for the concrete slab. The height of the housing relative to the base is adjusted to place the cap at the planned surface of the concrete slab. After the concrete slab is formed the cap is removed and the cut members inside the housing are connected to other members or devices.

  • Patent number: 9022326
    Abstract: A support for pipes uses a telescoping strut slidably holding an elongated insert with a threaded post extending outward from the insert, through a slot in the C-shaped cross-section of the struts. A bracket fits over the post and abuts supports opposing edges of the strut. A nut on the post clamps the parts immovably together. The bracket has a depending portion extending below the strut with an opening through which a pipe passes. Two threaded couplers with opposing ramped surfaces encircle the pipe and deform when tightened to clamp the pipe while also clamping opposing sides of the depending portion.
