One aspect of the invention provides a method of forming an energy-dissipative tube. In one embodiment, the method includes: extruding a resin layer over an outer surface of corrugated stainless steel tubing and impregnating the resin layer with metal particles. In another embodiment, the method includes: extruding a resin layer comprising a fire retardant over an outer surface of corrugated stainless steel tubing and impregnating the resin layer with metal particles. In another embodiment, the method includes: extruding a resin layer comprising between about 20% to 60% magnesium hydroxide, aluminum trihydrate, or halogenated fire retardants by weight over an outer surface of corrugated stainless steel tubing and impregnating the resin layer with metal particles selected from the group consisting of: copper, aluminum, gold, silver, and nickel.

A method of mounting an elastic ring, e.g. sealing ring, on a body via a mounting unit is presented, having at least three fingers which are movable relative to each other. The method comprises holding and clamping the ring on the exterior side of the fingers which extend into a cross-section framed by the ring, moving at least one finger along a circle or a plurality of fingers along a common circle or a plurality of concentric circles such that the elastic ring is stretched and the cross-section thereof is increased, moving the ring and the component relative to each other so that the component projects into the cross-section and the ring extends around the component, moving one or more fingers relative to each other so that the ring contacts the component in sections between adjacent fingers, and moving the fingers out of the ring. Also disclosed are a mounting unit for executing the method, and a ring mounting device including such a mounting unit.

An outer ring (29) is first transported to an insertion point (E) in the feed device (34). At the same time, a circular blank ring (30) is brought into a starting position (P) in the feed device. The circular blank ring (29) is first aligned coaxially with respect to an axis (A) using a centering body (61). The circular blank ring moves solely radially with respect to the axis (A). The circular blank ring (30) is then inserted into the hole of the outer ring (29). During this movement, the circular blank ring is aligned coaxially with respect to the axis (A) preferably using a centering channel (54). The circular blank ring (30) carries out a superimposed movement in the axial direction (V) and in the radial direction radially with respect to the axis (A).

A clip assembly for securing a sink to an opening in a countertop is disclosed. The clip assembly comprises a clip portion comprising a first portion having an opening, and a second portion spaced from the first portion. The second portion has a thruway, and the thruway includes a pawl. The clip assembly further includes a fastener portion comprising a head portion and a tape portion extending from the head portion. The tape portion includes a gear rack extending along a length of the tape portion. The tape portion is adapted for insertion through the opening of the first portion and the thruway of the second portion, such that the gear rack of the tape portion cooperatively engages the pawl.

The present invention generally relates to an innovative tool for connecting or disconnecting a runner to/from a shaft assembly. Moreover, the present invention relates to a method for carrying out such operations using the tool. Advantageously, connecting/disconnecting operations can occur without having to work under a suspended load, as the tool may be activated for supporting the runner remotely from a location outside a runner footprint.

An object of the present invention is to provide a device for installing a retaining ring on a shaft which can reduce the labor intensity of workers. The device for installing a retaining ring on a shaft comprises an expansion assembly. The expansion assembly includes a shell. A push block is movably fixed in the shell. Two expansion members that are symmetrical left and right are arranged in front of the push block. The expansion members include expansion portions that are located outside the shell and extend outward. Rear ends of the expansion portions are expansion portion first sections. The expansion members comprise a left expansion member on the left side and a right expansion member on the right side. The left end face of the expansion portion first section of the left expansion member is a slope extending leftward from rear to front. The push plate moves in a front-rear direction so that the expansion portions of the two expansion members move left and right, respectively. A loading rod is fixed on the lower side of the shell. A front edge of a front portion of the loading rod extends outward in a circumferential direction to form a limiting bump. A compression spring is sheathed on a rear portion of the loading rod. A front end face of the loading rod is recessed inward to form an evading groove.

A manifold having a first sub-manifold defining a first fluid passage, a second sub-manifold defining a second fluid passage, and a seal-sub occupying an interface between the first and second fluid passage and that seals against the first and second fluid passages to prevent fluid leaks at the interface. The first sub-manifold defines an opening for receiving the seal-sub into the first fluid passage from outside the first sub-manifold that is separate from the interface.

A method of manufacturing a component and a component manufacturing apparatus attach an attached part in a predetermined posture decided in advance to a ring-shaped channel formed in an outer circumference of a component main body. While being held by holding portions, a ring-shaped seal body is placed in contact with a tapered portion and has its diameter expanded to at least the outer diameter of the component main body. The seal body elastically deforms from the expanded-diameter state so that its diameter reduces and is attached to the attachment channel in the outer circumferential surface of the component main body while being guided by the holding portions.

A device for press-fitting an oil seal S that includes a fixing section F in which a hard ring S is embedded and a lip section L into a structure A. The device includes an air hammer AH that includes a hammer head 1. The hammer head 1 includes a pressing section 6 configured to abut the fixing section F and a holding section 7 configured to abut the lip section L, and a negative pressure space 8 is formed between the hammer head AH and the oil seal S between the pressing section 6 and the holding section 7. The hammer head 1 is provided with an air suction path 11 that is open to the negative pressure space 8 at one end and is connected to an air suctioning means 10 at the other end. Accordingly, the device holds by suction the oil seal S having a complicated shape without deforming it, and adequately press-fits it into a structure A.
