Patent number: 8572910Abstract: A wall-mounting block or frame is used to mount fixtures to exterior building walls having siding. The wall-mounting block includes two major parts, a first or base section and a second or holding section which are both configured as cap-like structures detachably connected to each other with integrated, adjustable connectors. The present design eliminates the need for special hardware to attach the holding section to the base section, and helps prevent awkward mounting situations.Type: GrantFiled: July 7, 2006Date of Patent: November 5, 2013Assignee: Tapco International, Inc.Inventor: Robert Hendricks

Patent number: 6325712Abstract: A ventilation assembly for ventilating an attic of a building through an opening in the roof or wall of the building. The ventilation assembly includes a vent structure having a mounting portion securing the vent structure to the building over the opening. The vent structure further includes a vent portion having a series of walls defining a series of unimpeded fluid passageways for providing unobstructed fluid flow through the vent portion over the opening. The ventilation assembly includes a partially porous membrane mounted to the roof or wall over the opening and spaced from the fluid passageway to maintain the unobstructed fluid flow through the fluid passageway. The membrane also creates a barrier for preventing the intrusion of particles, debris, insects and the like into the opening while allowing the ventilating to occur.Type: GrantFiled: May 31, 2000Date of Patent: December 4, 2001Assignee: Tapco International, Inc.Inventors: Jack Lawless, III, Charles Schiedegger, J.

Patent number: 6170528Abstract: Disclosed is an improved assembly of orifice chambers for reducing pressure of large gas flows effective to reduce noise of the gas flows and wear on orifice chambers by progressive pressure drops in the gas flows through successive orifice plates which are releasably secured, preferably by fillet welding, in each of the orifice chambers, removal of one or more orifice plates in an orifice chamber providing manway access to the next succeeding orifice chamber for inspection, repairs, and replacement of the orifice plates thereby reducing the manway opening or access to only one orifice chamber and eliminating separate access manways or manholes for each of the orifice chamber necessary for maintenance of the orifice chambers. Preferably, an internal shell providing an annular space with the body to which the orifice plates are connected is connected to the body by an annular ring and brace by fillet welding in compressions.Type: GrantFiled: July 26, 1999Date of Patent: January 9, 2001Assignee: Tapco International, Inc.Inventor: Marius Robert Junier

Patent number: 6109590Abstract: Disclosed is a control slide valve for control of product flow through it in which the valve internals are maintained in position by the clamping action of a split clamp and may be released and removed and replaced through the bonnet quickly and easily by release and reclamping the split clamp rather than by utilizing bolts which often gall, break, and are difficult to remove and replace. The slide valve is particularly suited for high temperature abrasive flow.Type: GrantFiled: February 12, 1998Date of Patent: August 29, 2000Assignee: Tapco International, Inc.Inventor: Andre F. Koerner

Patent number: 6050288Abstract: Disclosed is a slide valve for control of product flow through it in which the valve internals, an orifice plate and guide assembly, are maintained in position by a circumferentially extending attachment stub surrounding and welded to a circumferentially extending weld-on stub welded to the orifice plate, the circumferentially extending attachment stub being welded to an internal end of the support cone and to the weld-on stub whereby the internals may be released and removed through the bonnet area of the slide valve by cutting the weld between the attachment stub and the weld-on stub, and replaced through the bonnet area and rewelding the weld-on stub and the attachment stub with another fillet weld. This places the fillet weld under compression rather than under tension, and is much stronger than the tension fillet welds in previous embodiments of this slide valve. Also, the refractory material when used can be finished in the shop rather than on site.Type: GrantFiled: August 17, 1999Date of Patent: April 18, 2000Assignee: Tapco International, Inc.Inventor: Marius Robert Junier

Patent number: 5979870Abstract: The present invention constitutes an improvement over U.S. Pat. No. 5,269,493, and other butterfly valves controlling the flow of hot gases or other fluids under high pressures or velocities by having the valve stem not centered in which there is either no deflection or the deflection of the butterfly valve and rotation of the valve stem is substantially reduced when in a closed position resulting in no or substantially reduced leakage of the disc in closed position with respect to prior art butterfly valves currently in comparable use.Type: GrantFiled: March 2, 1998Date of Patent: November 9, 1999Assignee: Tapco International, Inc.Inventor: Marius Robert Junier

Patent number: 5301712Abstract: Disclosed is a slide valve for high temperature and/or abrasive service having a metal shell and a liner of refractory material forming a flowway having an inlet and an outlet and an orifice opening between them. A side opening closed by a removable bonnet intersects the flowway at the orifice opening and is provided with grooves extending transversely from the side opening to each side and beyond the orifice opening and forming upstream and downstream guide and slide shoulders. An orifice plate with an orifice is slidable into and out of position through the side opening, a slide or disc is slidable in the guides for movement to open, closed, and throttling positions. The orifice plate has a seal around its orifice which sealingly engages the upstream shoulder.Type: GrantFiled: July 12, 1993Date of Patent: April 12, 1994Assignee: Tapco International, Inc.Inventors: Lee E. Treichel, Gary J. Baumgartner

Patent number: 4316483Abstract: A valve is disclosed in which the wear-prone parts comprised of the valve, guides and valve seat are readily and easily removed through the bonnet area. The guides are maintained in position in the valve body by engagement with a stop and by securing the bonnet to the body without the requirement of being bolted to the body. Other features and details are disclosed.Type: GrantFiled: August 9, 1979Date of Patent: February 23, 1982Assignee: Tapco International, Inc.Inventor: Frank J. Jandrasi

Patent number: 4237362Abstract: Disclosed are methods of producing hardfaced plate which eliminates distortion while making weld deposits along the length of a sheet-like plate of relatively ductile and weldable material by securing the plate about a cylindrical supporting surface, then welding hardfacing material to the plate's surface which causes the plate to shrink against and be supported by the cylindrical surface which effectively maintains the plate against substantial distortion during the welding. The plate with the welded hardfacing material is then removed from the cylindrical surface. Preferably, the composition of the hardfacing material is such as to form random cracks at a frequency of not less than about one in each three inches upon cooling from the welding temperature, and preferably of the order of about 5/8" to about 3/4".Type: GrantFiled: September 28, 1978Date of Patent: December 2, 1980Assignee: Tapco International, Inc.Inventor: Roman F. Arnoldy
