A method of fabricating an acoustic device includes forming a plurality of holes in a panel, disposing the panel in a support frame, and heating the panel to a temperature such that the panel sags while disposed in the support frame and each hole of the plurality of holes is modified.

A multifunctional end effector includes a support structure configured to be carried by a robotic system and at least two of a fluid stream cutting system, a spindle system and/or a scanning system, each mounted to the support structure. Also described is a fluid stream cutting system having a plurality of fluid stream catchers selectively mountable to the fluid stream system and a mounting arrangement for mounting each fluid stream catcher to the fluid stream cutting system.

Methods for making an apertured polymeric film web or a composite structure web are disclosed. These webs may be utilized as a topsheet in an absorbent article and can provide fluid handling and softness benefits.

A glass container that includes a base defining a hole, and methods of manufacturing and using the glass container, is disclosed. The glass container is manufactured by providing the container and cutting a hole in a wall of the container. The hole may be cut into the wall by any technique in which glass material is separated from the wall including by mechanical shearing, thermal energy, and/or fluid impingement. To use the glass container, a deformable blow-out plug may be inserted into the hole to fluidly seal the hole, a liquid beverage may be introduced into the container, a closure may be coupled to the container to close the container and provide a pressurizable package, and thereafter the package may be internally pressurized by introducing a pressurizing gas into the package.

Methods and devices for the execution of core drillings in a material by a drilling unit, which makes use of a drill bit, and such drill bits that are made up of a hollow cylindrical core barrel, which has an end plate at its rear end and abrasion elements, which serve the abrasion of material, at the front end as well as at least two high-pressure jet nozzles, which can be connected with a high-pressure source of a blasting medium. The high-pressure jet nozzles are arranged on the inner surface of the core barrel and/or its end plate and are oriented into the inside of the core barrel. As a result of a combined forward motion and rotation of the drill bit, a drilling core is formed from which an abrasion takes place by means of the blasting medium, whereby overburden is removed from the drill bit.

System, apparatus and method for opening a heat-bonded connection formed between two hollow, flexible thermoplastic conduits. A pressure difference is created between the inside of at least one of the conduits and the ambient atmosphere sufficient to cause expansion of a wall of the tubing conduit in the vicinity of a frangible portion at least partially blocking the connection to disrupt the frangible portion and reduce the blocking.
