A method and device is disclosed for inserting a flexible, inflatable and electrically heatable bladder conveying and installing a thermally responsive repair material into the interior of a pipe. The device is portable and can be used to repair pipe accessible from only one location.

An improved precise control non-return valve assembly which is mounted on the front end of a helical rotating plasticating screw of an injection molding machine or the like that is surrounded by a heated elongated barrel and end-cap that forms a distribution chamber, whose purpose is to allow means for passage of molten plastic fluid in the downstream direction while preventing it in the opposite direction. The valve having an outwardly extended portion of a shaft and has a means to accept a rin...

A technique and tool are provided for repairing damaged areas of honeycomb structures. The tool includes a plurality of rods axially translatable into the damaged area. Foam material is inserted about the rods and allowed to cure. The rods are later withdrawn leaving a porous core of material. Sleeves may be provided to receive and support the rods as they translate into the damaged area. The sleeves may remain in the damaged area after the rods are withdrawn into the sleeves.

A pillar with a high aspect ratio is transferred by a nanoprinting method. In order to form a fine structure on a substrate, a nanoprinting apparatus heats and presses the substrate and a mold with a fine concave-convex pattern formed thereon, the mold having a mechanism for transferring and applying a mold-releasing agent. A method for transferring a fine structure using the aforementioned nanoprinting apparatus.

The present invention relates to apparatus, methods, and processes for making solid dosage forms comprising at least one active ingredient, a core and shell configuration, wherein the shell comprises a hardenable material, such as a thermal-gelling polymer, for example gelatin; and the shell is provided with at least one opening. The opening(s) are formed while the shell is still in a softened state.

An injection molding assembly having a mold cavity assembly, a stripping apparatus and a mold core assembly. These components are movably coupled together and configured to extract, remove or eject a molded part. The injection molding assembly also includes a biasing member or force transceiver to facilitate in the removal of the molded part from the mold core.

A straightening apparatus for straightening carpet prior to laying the carpet on a floor surface. The apparatus includes an entry conveyor from which carpet is unrolled and fed into a heating section. In the heating section, the carpet is heated sufficient to soften backing material on the carpet. The heated carpet is then fed into a heated straightening section where longitudinal forces are applied while the backing is still soft so that a pattern in the carpet is straightened and held in the s...

An improved take-off device for an injection molding machine that includes an extensible sleeve for extending a suction channel during transfer of parts from the mold core assembly to the take-off device, the tube being retractable after the parts have been transferred.

A pick and place tool including a part penetration element adapted to induce a generation of a compressive force by the part against the part penetration element, securing the part to the part penetration element. The pick and place tool secures a part at first location employing an induced compressive force by the part against a part penetration element of the pick and place tool. In one embodiment, a pick and place tool for picking a part while maintaining a selected part orientation includes ...

A mold structure includes an ejecting tube disposed movably within a guide hole in a lower mold unit and having an ejecting end. The ejecting tube is communicated with an air chamber in the lower mold unit and a mold cavity. A pneumatic device is operable to draw air from the mold cavity into the ejecting tube. The ejecting tube is operable to move within the guide hole between a retracted position whereat the ejecting end is disposed outwardly of the mold cavity, and an ejecting position wherea...
