APPARATUS AND METHOD FOR RESISTIVE IMPLANT WELDING OF REINFORCED THERMOSETTING RESIN PIPE JOINTS IN A SINGLE STEP PROCESS
A system for coupling pipes includes a first pipe having a tapered, spigot end; a second pipe having a tapered, spigot end; a coupler having two tapered socket ends adapted to internally receive the respective tapered, spigot ends of the first pipe and the second pipe; and a resistive element. The first pipe, the second pipe, and the coupler are made from a reinforced thermosetting resin (RTR). The resistive element includes a first layer and a second layer of thermoplastic material; and an electrically conducting resistive heating element with positive and negative terminals for connecting electrical power. The electrically conducting resistive heating element is sandwiched by the first layer and the second layer of thermoplastic material. The resistive element is disposed between an interior of the coupler and at least one of: an exterior of the first pipe and an exterior of the second pipe. Upon application of electrical power to the positive and negative terminals of the resistive element, the electrically conducting resistive heating element generates heat sufficient to melt the thermoplastic material such that, when the heat is removed, the hardened thermoplastic material seals the first pipe and/or the second pipe to the coupler.
Controlled translation method of affixing a termination to a tensile member
A method for creating a termination by attaching some kind of fitting to the end of a tensile member such as a cable. The end fitting is provided with an internal cavity. The cavity has a proximal portion that is adjacent to the area where the tensile member exits the fitting and a distal portion on its opposite end. A length of the tensile member's filaments is placed within this expanding cavity and infused with liquid potting compound. The method exploits the characteristic of a liquid potting compound as it transitions to a solid. The potting compound in one portion of the cavity is typically transitioned to a solid at a more rapid rate than other portions. Once the potting compound in one portion of the cavity has transitioned sufficiently to hold the filaments at the desired level, tension is placed on the tensile member and a small linear displacement may be imposed on the tensile member. This linear displacement tends to pull the filaments residing in the potting compound into better alignment and improve load sharing.
WELDED ON CATHETER HUB
The disclosed technology includes a catheter or sheath assembly and a method for manufacturing same. The manufacturing process includes obtaining a catheter or sheath having a distal end and a proximal end, and obtaining a hub pre-formed separately from the catheter or sheath. The hub can include a pre-formed receptacle portion configured to receive a portion of the catheter or sheath. A portion of the catheter or sheath can be inserted into the pre-formed receptacle portion of the hub. The receptacle portion can be melted to a semi-fluid state and can be compressed against the portion of the catheter or sheath in the hub.
Food container top with integrally formed utensil
A molded article comprising a food container top, and a method for producing same, is disclosed. The method includes providing a mold for forming the molded article, wherein the mold defines a frame, a utensil located substantially coplanar with the frame and a frangible link between the frame and the utensil, providing an in-mold lidding film having a heat activatable lower surface, positioning the in-mold lidding film adjacent to an interior molding surface of the mold, molding the molded article from a heated thermoplastic resin contained within the mold, whereby the heated thermoplastic resin contacts a perimeter of the heat-activatable lower surface of the in-mold lidding film, and the perimeter of the heat-activatable lower surface of the in-mold lidding film is molded to the frame of the article such that the in-mold lidding film hermetically seals an opening defined by the frame.
Pipe coupling construction, and coupling
A pipe coupling construction which can be used for coupling of a high-pressure pipe includes an inner bush of a non-metallic material and an outer bush, which bushes in axial section have parts which mesh with each other in order to transmit axial forces. The inner bush can be fused or adhered to an outer cover layer of the pipe. The coupling has a metal sleeve construction. The outer bush has an outer bush protruding end which protrudes with respect to the inner bush and the metal sleeve construction is at least partially located within the outer bush protruding end. The metal sleeve construction and outer bush in axial section have parts which mesh with each other.
WELDING ASSESSMENT DURING WELDING PROCESS
A method and a system including a welding device, an inspection device having an inspection head having two sensors, a controller, and a memory for assessing a butt weld of plastic pipes or fittings in a welding device.
METHODS FOR ASSEMBLING A CARTRIDGE FOR AN AEROSOL DELIVERY DEVICE, AND ASSOCIATED SYSTEMS AND APPARATUSES
The present disclosure relates to systems, apparatuses, and methods for assembling cartridges for aerosol delivery devices. A system may include assembly cells each including an assembly track and assembly carriages that ride thereon and which engage components of partially-assembled cartridges.

The platforms may include assembly grippers with sequentially-opening clamps configured to receive the components of the partially-assembled cartridges. Related methods are also provided.
Leak testing of a pressure vessel
An end cap for a pressure vessel has at least one part for connecting the end cap to a housing. The at least one part comprises a number of recesses. The recesses are arranged to form at least one fluid passage between an inside and an outside of the end cap when the end cap is plugged on the housing. A housing for a pressure vessel has at least one counterpart for connecting an end cap to the housing by engaging a part of the end cap. The at least one counterpart comprises a number of recesses. The recesses are arranged to form at least one fluid passage between an inside and an outside of the housing when the end cap is plugged on the housing. A method for leak testing a pressure vessel and a method for checking a connection between at least one end cap and a housing of a pressure vessel for leak tightness are also described.

Creation of a polymer retention hub to form a conjunct nozzle
A novel design of a polymer retention hub created having an innovative feature used to permanently attach a thin wall nozzle core without use of adhesives or ancillary parts to form a conjunct nozzle. Additional polymer in the correct amount is molded into a polymer retention hub in close proximity to a location where a mechanical lock must be formed to join the two components together. The inventive design of the polymer retention hub is configured to produce an enclosed cavity with the strength required for separation of a nozzle core from a standard taper.
