  • Patent number: 10533291
    Abstract: The snow melting mat includes an elongate, substantially flat sheet of a desired length connected to a recirculation header at one end and a circulation header at the opposite end. The sheet includes a plurality of channels defined inside the sheet. The channels permit heated liquid to circulate along the length of the sheet. A heater-pump heats the liquid that maintains the temperature of the sheet at several degrees above freezing and pumps the liquid through the recirculation header, the sheet, and the circulation header. A plurality of transverse grooves is formed on the top of the sheet to provide a gripping, walking surface. The grooves taper in depth to permit melted snow and ice to run off the sides of the sheet. Couplers and joints permit multiple sheets to be joined together in any desired pattern.

  • Patent number: 8628117
    Abstract: The instant disclosure relates to a push-fit ring-seal joint structure for plastic pipes. For the joint structure, a lip portion tapers away from the pipe outlet, while a throat portion tapers toward the pipe outlet. The joint structure allows the angular deflection to be increased by three or four times versus the conventional push-fit joint, while maintaining excellent sealing and pressure rating. By the unique design of the joint structure, the structural flexibility of pipe connection can be increased. When there is ground movement due to land subsidence or earthquake or adjustment in pipe route, the coupled pipe can maintain excellent sealing and pressure rating. Therefore, the joint structure of the instant disclosure indeed has novelty and industrial applicability.

  • Patent number: 8573654
    Abstract: An annular sealing material seals a pipe joint between a socket and a spigot. The sealing material includes a bulb part which is composed of a first bulb, a second bulb located closer to the inner side of the socket than the first bulb, and a narrow part present between the first and second bulbs. The first bulb is pressed against the inner circumferential surface of the socket. The second bulb is pressed against the outer peripheral surface of the spigot. The second bulb is inclined towards the pipe center from the first bulb in a natural state before it is provided between the socket and the spigot. The inner diameter of the second bulb is smaller than the outer diameter of the spigot in the natural state. The second bulb is extensible in the pipe diameter direction due to elastic deformation of the narrow part.

  • Patent number: 8534572
    Abstract: A riser seal cartridge for an irrigation sprinkler. The cartridge is formed of a rigid self support shell, and a sealing member formed of a resilient material covering the shell in areas which provide the seal. The sealing member includes a first portion which seals the top end of the sprinkler body, a second portion which seals an outer surface of the riser, a third portion which connects the first and second portions, and a fourth portion extending from the third seal portion which provides a seal for the support shell lower end portion. The first seal portion provides a high pressure seal to prevent leakage when the riser is in a fully extended position; and the second seal portion provides a low pressure seal during pressure build-up as the riser is extending.

  • Patent number: 8528945
    Abstract: A pipe coupling for coupling adjacent ends of a pair of pipes includes a sleeve, a split-ring gland positioned around one of the ends of the sleeve, and an annular gasket positioned within the split-ring gland and configured to be compressed by the split-ring gland for sealing one pipe end to the sleeve. The split-ring gland includes two partially circular gland members with spaced ends defining a gap, which is spanned by an armor positioned in the gap to provide a generally closed annular periphery about the gasket. The armor includes a corrugated portion engaging the gasket during compression. The gasket includes a pressure assist slot configured to receive pressurized fluid leaking from the pipes and a plurality of cross grooves ensuring continued fluid communication with the pressure assist slot. The gasket also includes ribs engaging the split-ring gland and the armor to reduce or eliminate added lubrication necessary.

    Abstract: This tubular joint includes a bell end (4) which is equipped with an internal groove (18) and in which is inserted a spigot end (6), a seal (8) and a locking element (12). The groove forms a groove wall (20). The spigot end (6) and the bell end (4) define a radial clearance (J). The locking element (12) includes a fixing tooth (36) and a contact face (28) for application against the wall (20) when the clearance (J) is within a first range of clearances. When the clearance is within a second range of clearances, the locking element (12) forms a rocking point (34) for rocking round the groove wall (20) and the fixing tooth (36) bites into the external surface (22) by a flying buttress effect of the locking element (12).

  • Patent number: 8074996
    Abstract: An sealing gasket is shown for use in forming joints of plastic pipe. The gasket has a bulbous region which is bisected by a planar region which forms a pair of oppositely extending wing-like flaps. These features of the gasket allow it to be more reliably seated on the working mandrel used to bell a female, thermoplastic pipe end. The wing-like flap portions of the gasket form wiper surfaces for a subsequently installed male, spigot pipe end as the joint is formed.

  • Patent number: 8075025
    Abstract: A crown-type probe seal for a female hydraulic coupling member has one or more pressure-energized seals for sealing between the probe seal and the body of the coupling member which retains the probe seal. The generally ring-shaped probe seal has one or more annular fluid chambers in the wall of the seal's body. Each annular fluid chamber is open to the outer circumference of the probe seal. Hydraulic fluid under pressure may enter an annular fluid chamber through its opening and exert a generally radial force as a result of a pressure differential. This radial force can act to increase the sealing effectiveness of the probe seal both to the body of the coupling member retaining the probe seal and to the probe of a male coupling member inserted in the receiving chamber of the female member.
