The present invention relates to an automobile urea tank produced using a forming method. The method includes the following steps: (a) producing an upper half casing and a lower half casing through an injection molding method; (b) after the upper half casing and the lower half casing are formed, assembling built-in parts of the upper half casing and the lower half casing; (c) welding the assembled upper half casing and the assembled lower half casing to form a whole; and (d) assembling components on surfaces of the upper half casing and the lower half casing. This method can improve design freedom of built-in elements of the tank body, and can save a lot of raw materials; the structure is simple and firm; moreover, the production efficiency is improved, and the production cycle is shortened.

An assembly and method for attaching an engine pylon to an aircraft wing. The method may include attaching a first forward wing-mounted fitting to the pylon at a first side of the pylon between upper and lower spars of the pylon and attaching a second forward wing-mounted fitting to the pylon at a second side of the pylon between the upper and lower spars of the pylon. The second side of the pylon is located opposite of the first side of the pylon. Mechanical attachment devices may be inserted through holes on the sides of the pylon aligned with holes formed through the forward wing-mounted fittings. The mechanical attachment devices may be made of steel and the forward wing-mounted fittings may be made of composite or aluminum material.

A travel case that converts from a palletable shipping container into one or more display cabinet(s) and/or table(s). In some embodiments, the container includes first and second dual-box units each having two open-faced boxes connected to one another along an edge of each by a first hinge. One box of each unit includes a bottom pallet portion to allow the apparatus to be lifted and carried by a forklift. In some embodiments, the first unit unfolds from a stacked configuration where its first box is stacked upon its second box to a dual-table configuration where the first box is side-by-side the second box, and wherein the height of the second box including the bottom pallet portion is substantially equal to the height of the first box. In some embodiments, a second unit connects to the first unit to enclose the inner volumes of the first and second box.

A method for sealing surgical instruments, particularly reusable electric surgical instruments sterilized using an autoclave process, is disclosed. The method having the steps of providing at least two body shells having a runner system on the mating surfaces, aligning the body shells, securing the body shells in position relative to each other, inserting an injection device into the runner system, injecting an elastomer material from the injection device into the runner system, removing the injection device from the runner system, and curing the elastomer material. The elastomer material seals the housing chamber of the instrument. The elastomer material may bond the body shells together.

A rigid coupler for use in electrically isolating an electrically conductive fluid conveyance system is described. The rigid coupler includes a nonconductive liner having a first end configured to couple to a first adjoining section of the fluid conveyance system, and a second end, opposite said first end, configured to couple to a second adjoining section of the fluid conveyance system. A reinforcing structure circumscribes the nonconductive liner and is coupled to a portion of the nonconductive liner extending between the first and second ends of the nonconductive liner. The reinforcing structure includes a multi-axial braided fiber material impregnated with a matrix material. A fiber overwrap is hoop wound about at a least a portion of the reinforcing structure between the first and second ends of the nonconductive liner.

The invention relates to a compressed air tank for utility vehicles, comprising a tubular or cylindrical jacket sealed at both ends by way of welded outer bases. At least one outer base and/or the jacket is provided with a hole. A sleeve is welded onto the hole. At least the inside of the compressed air tank is provided with an inner coating. The contact surfaces between the jacket and the outer bases are adapted such that the contact surfaces abut one another and such that the contact surfaces can be welded together without using any weld material through laser welding. The sleeve is welded onto the hole by way of laser welding or CD welding. The inner coating of the tank is manufactured by powder coating.

Disclosed is a fluid reservoir shell that provides protection for the fluid reservoir of a personal hydration system. The fluid reservoir shell is rigid and does not collapse easily under external pressure. The fluid reservoir shell is sized to contain the fluid reservoir but still fits in a personal hydration system pack. The shell protects the fluid reservoir and prevents the fluid reservoir from leaking due to excessive external pressure. The fluid reservoir shell disclosed includes a shell top piece and a shell bottom piece, which couple together to enclose the bladder of the fluid reservoir. The fluid reservoir shell provides ready access to the fill port and the drink tube of the fluid reservoir when the fluid reservoir is contained in the fluid reservoir shell.

Systems and methods for a robust underwater vehicle are described herein. A robust underwater vehicle may include a force-limiting coupler connecting an actuation system to an actuation fin. The force-limiting coupler may be configured to break away from the actuation system upon receiving a threshold force. The robust underwater vehicle may also comprise hull sections connected by a threaded turnbuckle. Carbon-fiber axial strength members may mate with the threaded turnbuckle to pull the hull sections together to a specified preload tension. The robust underwater vehicle may also include a blazed sonar array protected by a carbon fiber bow including a plurality of slits. The plurality of slits may provide significant protection to the sonar array while simultaneously allowing one or more transducers to transmit sonar signals in a two-dimensional plane.
