Patent number: 9719621Abstract: In a snap tap forming method, a partition wall formed along a curvature of a water pipe outer peripheral wall surface is brought into hermetical pressure contact with the water pipe outer peripheral wall and is mounted on the outer peripheral wall at a position corresponding to an inflow opening portion of a gate valve and at which a snap tap of the water pipe is formed. A center drill guide small hole aligned with the snap tap axis is drilled in a center portion of partition wall. A drilling machine inserted in a water flow sleeve of the gate valve is inserted into the aforementioned small hole. A water diverting port is formed in the partition wall and a peripheral wall of the water pipe using a core drill by advancing the drilling machine while estimating a drilling center. Then the drilling machine is removed from a water flow passage in the gate valve, and the snap tap is connected to the water diverting port by a snap tap attaching tool.Type: GrantFiled: March 24, 2014Date of Patent: August 1, 2017Assignee: Yone CorporationInventors: Toyohiko Yoneda, Tetsuzo Yoneda, Norio Doman

Patent number: 9719622Abstract: An electrofusion fiting (20) comprises a fitting body (24) and an electrofusion collar (26). The fitting body (24) has an exterior surface (30), an interior surface (32), and a terminal portion (44) extending to a rim (34). The collar (26) has: an inner wall (42) having a heating element (60); a segmented outer wall (40) spaced radially apart from the inner wall; and a linking portion (46) linking the outer wall and inner wall. The fitting body terminal portion is between the inner wall and the outer wall. The collar and fitting body have interfitting features (150, 152) axially retaining the collar against extraction from the fitting body while permitting relative rotation of the collar and the fitting body.Type: GrantFiled: June 30, 2014Date of Patent: August 1, 2017Assignee: Georg Fischer Harvel LLCInventor: Phillip P. Schmidt

Patent number: 9719623Abstract: A fluid pipeline has a first end and a second end. An elongated heat trace element comprised of first and second heat tubes is aligned and coupled to at least a portion of an outer surface of the fluid pipeline. The outer surface of fluid pipeline carries a first insulation material covering a first portion of the outer surface. The outer surface of the fluid pipeline further carries a second insulation material covering a second portion of the outer surface and wherein the second portion of the outer surface is different than the first portion of the outer surface. The first and second insulation materials are configured to cover the outer surface of the fluid pipeline. The fluid pipeline further comprises a third insulation material carried over a second outer surface defined by the cooperation of the first and second insulation materials.Type: GrantFiled: September 15, 2011Date of Patent: August 1, 2017Assignee: Pentair Thermal Managment LLCInventor: Franco Chakkalakal

Patent number: 9719625Abstract: A pig handling device has a housing, a cavity found in the housing in which a pig can be received, a connection by means of which the cavity is connectable to a processing system, the connection suitable for allowing the pig to pass through, and a handling element that is arranged in the cavity, influences the mobility of the pig in the cavity, and has a base element and a functional element. The base element has a first surface, and the functional element is connected to the base element in the cavity and has a second surface. The arrangement improves cleanability in that the handling element has a concavely curved transition surface arranged between the first surface and the second surface and having a core curvature region, and in that the base element and the functional element are bonded to one another outside of the core curvature region.Type: GrantFiled: July 14, 2014Date of Patent: August 1, 2017Assignee: GEA Tuchenhagen GmbHInventor: Jens Burmester

Patent number: 9719626Abstract: An insulation system insulating a carrier conduit carrying a hot gas or liquid, buried in permafrost, allows expansion and contraction of said carrier conduit, and directionally disperses heat from the conduit minimizing thawing of permafrost. A carrier conduit carries a gas or liquid. A carrier insulation encases the carrier conduit. An outer conduit encases the carrier insulation. The outer conduit top portion includes two symmetrical flanges integrally formed on two sides of said outer conduit. An outer insulation partially encases the outer conduit. There is no outer insulation on the upper part of outer conduit; and thus, outer conduit top portion remains selectively uncovered. Any heat escaping through the carrier insulation, travels in a circumferential direction along the outer conduit and not in a radial direction because of outer insulation. The heat escapes in the soil above the insulated conduit, protecting the permafrost.Type: GrantFiled: December 23, 2014Date of Patent: August 1, 2017Inventor: Muhammad Amzad Ali

Patent number: 9719627Abstract: A stand includes a base, a first tube coupled to the base and extending therefrom, the first tube defining a first bore having an opening at an end of the tube opposite the base, and a second tube, a portion of which is received in the first bore such that the second tube and the first tube form a telescoping relationship, the second tube comprising a first section and a second section, the first section and second section being connected via a clutch, the clutch being configured to enable articulation of the second section relative to the first section about the clutch. The clutch has an outer cross section that is configured to be received in the first bore when the first section is coaxial with the second section.Type: GrantFiled: August 25, 2015Date of Patent: August 1, 2017Assignee: The Music People, Inc.Inventor: James R.

Patent number: 9719628Abstract: A mounting system for supporting equipment above a surface, such as, for example, a label dispensing unit, is provided. The system includes bracket having a first segment cantilevering from a housing and a second segment extending perpendicularly from the first segment and spaced apart from the housing. The housing and first and second segments form a channel to receive a support structure therein. The support structure is sized to fit within the channel to support the equipment above a surface when the bracket is disposed over the support structure.Type: GrantFiled: October 26, 2012Date of Patent: August 1, 2017Assignee: Start Manufacturing, Inc.Inventor: Todd Sternberg
