A manufacturing process for making different expansion tanks for different cooling systems and/or for different engines, each of said expansion tanks having an inlet mouth and comprising: a plastic shell comprising a) a wall defining a cavity for containing a coolant liquid; and b) at least one collar at said inlet mouth, said collar being outwardly projecting from said wall. Each of said expansion tanks further comprising a tubular insert engaging said collar and defining said inlet mouth; said tubular insert being made of plastic material colored in mass; and retention means which hold said tubular insert relative to said collar. The process comprising making shells identical in shape and size, for all of said expansion tanks; and making inserts that differ in the value of their inner diameter; each inner diameter value being determined at the design stage depending on the type of cooling system and/or the type of engine.

An inner housing defines a pin retaining receptacle elongated in an X-direction with entry ramps extending parallel to the X-direction. The inner housing is slidably coupled to an outer housing and extends into an interior thereof. A plurality of centering blades extend into the interior and between the inner and outer housings to locate the pin retaining receptacle in a central position within the interior in a Y-direction prior to insertion of the pin into the pin retention receptacle. The centering blades are movable in the Y-direction to permit the pin retaining receptacle of the inner housing to move to a non-central position relative to the housing in the Y-direction as a result of the inner housing moving the centering blades in response to the pin engaging the entry ramps during insertion of the pin into the pin receiving receptacle. Associated methods are also disclosed.

A method is provided which forms a closed section hollow structural element by performing the following steps which include press forming an upper sheet metal component configured with two primary parallel downstanding interface flanges; press forming a lower sheet metal component configured with two primary parallel upstanding interface flanges; complementarily trimming the downstanding interface flanges and the upstanding interface flanges using five-axis laser cutting; and butt welding the interface flanges of the upper and lower sheet metal components to one another to form a continuous hollow structural element of variable cross section.

Systems and methods are disclosed herein for a pressure tolerant energy system. The pressure tolerant energy system may comprise a pressure tolerant cavity and an energy system enclosed in the pressure tolerant cavity configured to provide electrical power to the vehicle. The energy system may include one or more battery cells and a pressure tolerant, programmable management circuit. The pressure tolerant cavity may be filled with an electrically-inert liquid, such as mineral oil. In some embodiments, the electrically-inert liquid may be kept at a positive pressure relative to a pressure external to the pressure tolerant cavity. The energy system may further comprise a pressure venting system configured to maintain the pressure inside the pressure tolerant cavity within a range of pressures. The pressure tolerant cavity may be sealed to prevent water ingress.

The present invention relates to a lighting device, which comprises a structure of interconnected sleeves and a light emitting arrangement arranged inside the sleeves. The structure forms a polygon mesh and light sources on the light emitting arrangement can be positioned by the structure so that the problem of glare can be reduced. The present invention also provides a sound-absorbing, flexible and collapsible structure which can be used in e.g. large scale architectural panels, horticulture and phototherapy devices. The lighting device can be produced by connecting the sleeves with thermoplastic material or by sewing.
