摘要:
A coupling may be configured to receive and secure an insertion end of a conduit. An outer surface of the insertion end of the conduit may be smooth and free of grooves, flanges and beads. A first member of the coupling may define a first passageway. A second member of the coupling may define a second passageway. The first member may be in spin weld engagement with the second member. A gripping ring having an inner edge defining a series of teeth may be disposed within the second member. A support ring and O-ring may also be disposed within the second member.

An electrical heating bonding device 1 bonds a member M1 to be bonded, which is made of a metal, and a member M2 to be bonded, which is made of a resin. The electrical heating bonding device 1 includes: an upper electrode 11 and a lower electrode 12 which sandwich the member M1 to be bonded, and are electrically conductive with the member M1 to be bonded; a pressurizing unit 20 which applies pressure to a bonding surface between the member M1 to be bonded and the member M2 to be bonded; a temperature sensor 30 which detects a temperature of the member M1 to be bonded; and a control unit 40 which controls the pressurizing unit 20 to apply the pressure to the bonding surface, after the temperature detected by the temperature sensor 30 reaches a predetermined set temperature Ts.

A pallet container for the storage and transport of liquid or free-flowing goods, includes a thin-walled inner container of thermoplastic material, a tubular lattice frame closely surrounding the inner plastic container in the form of a support jacket, and a bottom pallet upon which the inner plastic container rests and with which the tubular lattice frame is securely fixed. The inner plastic container includes for withdrawal of liquid goods at the lower side, approximately in mid-section in a side wall near its bottom a blown, calibrated tubular pipe for allowing attachment of a closeable discharge fitting which is fixedly welded with its tubular housing to the calibrated tubular pipe of the inner container.
摘要:
A pass-through formed of material unweldable to a non-metallic tank has an adaptor ring formed of material also unweldable to the tank which is welded to the pass-through body. Prior to welding the adaptor ring to the pass-through the adaptor ring is chemically bonded to a mounting ring, which is formed of material weldable to the tank. The assembly thus formed may then be welded to the tank.

A backrest includes a frame, a web and a ring. The frame includes a margin and two rims extending on a side of the margin and a gap defined between the rims. The web is spread on the side of the frame. The ring is put on the web and fit in the annular groove so that the web is tightly spread on the frame.
摘要:
A method for the production of a laminate consisting of metal layers as well as at least one fibre-reinforced bonding layer (5-7) that is located between the metal layers (1-4), which laminate has at least one region (9) that has a smaller number (3, 4, 7) of layers than the reminder of the laminate, comprises the following steps: forming a stack (8) consisting of metal layers (1-4) and at least one fibre layer (5-7) impregnated with a binder, which stack (8) has a first series (11) of successive layers (1, 2, 5, 6) with a different surface size to a second series (12) of successive layers (3, 4, 7), such that one (12) of the series of layers protrudes with respect to the other series (11) of layers, placing an auxiliary tool (14) at the protruding portion (19) of the protruding series (12) of layers alongside the other series (11) of layers, which auxiliary tool (14) has a make-up that is the same as that of said other series (11) of layers, activating the fibre-reinforced bonding layers (5, 6, 7) under elevated pressure and temperature with the formation of the laminate.

An RF heating system. In one aspect of the present invention, the RF heating system includes a first elongated electrode connected to a first node within an impedance matching circuit and a second elongated electrode connected to a second node within the impedance matching circuit, wherein (a) a first portion of the first electrode and a first portion of the second electrode are adjacent to and substantially parallel with each other, (b) a second portion of the first electrode is angled in a direction away from the second electrode, (c) a second portion of the second electrode is angled in a direction away from the first electrode, and (d) a stray electromagnetic field is generated in a region above the space between the first portion of the first electrode and the first portion of the second electrode, whereby the generated stray field can be used to heat a composition when the composition is placed in the region.
摘要:
A twist-on renewable filter comprising a one-piece hollow housing, made of polymeric material having a threaded adapter for attachment to a distribution head assembly. The filter housing is fabricated from components that are made of a polymeric material that are fused together to form the one-piece hollow housing. A filter media assembly is rigidly bonded at both ends within the housing. The renewable filter has an infinite life and can be removed and cleaned, for example, by reverse flushing the filter with a cleaning solution. A bypass valve 250 is provided within the filter that is designed to provide full closure for an infinite life. The bypass valve 250 is fully located within the one-piece hollow housing such that it cannot be disabled or tampered with. The bypass valve 250 functions to allow sufficient fluid to bypass the filter media when the filter media has become contaminated and will not permit the full volume of the normal oil stream to be filtered. The bypass valve 250 has the capacity to permit the full volume of the normal oil stream to bypass the filter media when necessary, for example, during a cold start.
