Abstract:
The method to radially displace liquid liner inside a pipe includes the step of flowing the liner around a distributive body placed within a pipe gas stream. As the gas streams past the distributive body, the liner coats the pipe homogeneously from top to bottom.
Abstract:
A sealer gun that discharges a liquid of a coating agent or filler from a nozzle on its tip is securely prevented from producing dripping that arises as a liquid drips from the nozzle tip and remains when the liquid discharge stops. A pump including a cylinder and a freely movable piston fitting therein is assembled onto a discharge cylinder of the sealer gun, an operation rod interlocked with the pump piston and a grip are interlocked via an interlock mechanism to perform pump operation of suction-discharge by movement of the piston caused by pivoting of the grip, and a suction-discharge aperture of the pump is positioned in an internal space of the nozzle, and configured so that when the liquid discharge sops by releasing the grip, a negative or positive pressure is introduced into the nozzle because of the pump operation caused by resilient pivoting of the grip.
Abstract:
A gluing nozzle can include a base defining a receiving cavity, and a tube coupled to the base. The tube can include a straight portion mounted to the base, and a bent portion bent from the straight portion. The tube can define a channel fluidly communicating with the receiving cavity, the straight portion, and the bent portion. The channel can extend through an outlet of the bent portion. A distal end of the bent portion can form an annular surface surrounding the outlet. The annular surface can be substantially parallel to an axis of the straight portion.
Abstract:
A nozzle assembly includes an inner tubular member having a closed end and an opposed open end for receiving a fluid from a source, at least one outlet extending radially through the inner tubular member proximate the closed end, wherein the closed end is configured for insertion into a bore defined by a sidewall in a work piece. The nozzle assembly further includes a slidably movable outer sleeve, having a distal end, disposed around the inner tubular member, wherein the distal end is configured for contact with an exterior edge portion of the bore. The outer sleeve is normally biased to a first position sealing the at least one outlet from the exterior, and slidably movable to a second position unsealing the at least one outlet upon contact with the edge portion of the bore as the closed end of the inner tubular member is inserted into the bore.
Abstract:
Embodiments described herein relate generally to devices, systems and methods for producing liquid impregnated surfaces with enhanced durability. In some embodiments, a liquid-impregnated surface includes a first surface having a first roll off angle. A plurality of solid features are disposed on the first surface, such that a plurality of interstitial regions are defined between the plurality of solid features. An impregnating liquid is disposed in the interstitial regions. Furthermore, the interstitial regions are dimension and configured such that that the surface remains impregnated by the impregnating liquid. The impregnating liquid disposed in the interstitial regions defines a second surface which has a second roll off angle less than the first roll off angle. The apparatus also includes a liquid delivery mechanism configured to transfer the impregnating liquid to the interstitial regions.
Abstract:
Apparatus for making a pack tray includes a body with a strip of side walls, the body including an outer envelope lined on the inside with an added sealed plastic film. The apparatus includes at least one station provided with elements for applying glue on a portion at least of the inner surface of the side wall strip of the outer envelope, also called gluing area, before placing a plastic film. The gluing pads include at least one block of a porous material that can, one the one hand, be filled with glue by loading members through a diffusion phenomenon, and that can deposit glue by contact optionally combined with a compression force on the gluing area. The pad is mounted on a bearing structure via members for handling it between expanded positions in which the pad contacts the gluing area for applying glue thereon and a folded position in which the gluing pad is remote from the outer envelope of the pack tray.
