TL;DR: In this article, an end-stop damper consisting of a damper body in the form of a cylinder and a bellows section is designed to be connected to each other in such a way that they are formed in one piece.
Abstract: The invention relates to an end-stop damper comprising a damper body in the form of a cylinder (11), wherein a piston (43) is guided in such a way that it is displaceable in the cylinder receiving chamber (11,1), an air pressure which is formed in the receiving chamber produces a braking force acting on the piston during the displacement thereof, the receiving chamber comprises at least one pressure reducing opening (16) and the piston comprises a bellows section (44) which is actively connected to the cylinder according to pressure conditions in the receiving chamber. The aim of said invention is to substantially simplify the structural design of the end-stop damper by ensuring that the piston and the bellows section are connected to each other in such a way that they are formed in one piece.

TL;DR: In this paper, a flexible coupling for an insulated piping system of the type used to convey steam and other high temperature fluids is presented, which uses a flexible bellows and additional insulating and joining components to couple conventional lengths of insulated pipe.
Abstract: An flexible coupling is shown for an insulated piping system of the type used to convey steam and other high temperature fluids. The coupling uses a flexible bellows and additional insulating and joining components to couple conventional lengths of insulated pipe. The bellows arrangement compensates for any relative movement of the inner fluid conveying pipes with respect to the outer layers of insulating material and outer jacket in order to protect the integrity of the assembly and prevent the intrusion of water or other contaminants which could lead to corrosion or early failure of the piping system.

TL;DR: An exhaust manifold for an internal combustion engine with at least two cylinders includes two adjacent connection branches which are interconnected by collection pipe sections having an expansion compensating bellows for accommodating differential thermal expansion there between and a gas flow guide pipe structure which extends into the bellows as discussed by the authors.
Abstract: An exhaust manifold for an internal combustion engine with at least two cylinders includes at least two adjacent connection branches which are interconnected by collection pipe sections having an expansion compensating bellows for accommodating differential thermal expansion therebetween and a gas flow guide pipe structure which extends into the bellows At least one of the collection pipe sections comprises a multi-layered pipe wall with which the expansion compensating bellows is integrally formed

TL;DR: In this paper, a pneumatic apparatus includes a treadle bellows fluidically communicated with a follower bellows of which an upper bellows flange is secured with a toilet seat and a lower bellows is secured on a toilet bowl.
Abstract: A pneumatic apparatus includes a treadle bellows fluidically communicated with a follower bellows of which an upper bellows flange is secured with a toilet seat and a lower bellows flange secured on a toilet bowl, whereby depressing the treadle bellows compresses air into the follower bellows for expanding the follower bellows, the toilet seat and cover will be lifted, and upon a releasing of the treadle bellows the air in the follower bellowers will be sucked into the treadle bellows to contract the follower bellows to lower the seat and the cover for relevant uses.

TL;DR: A "soft" support system, preferrably utilizing pneumatic bellows, capable of supporting a ship hull in a relatively level condition on its building foundations or ways during construction and during moving operations is described in this article.
Abstract: A "soft" support system, preferrably utilizing pneumatic bellows, capable of supporting a ship hull in a relatively level condition on its building foundations or ways during construction and during moving operations; the system uses either a dynamic or a static "soft" support insert between the basic "hard" foundation supports and the vessel shell; in addition to the preferred pneumatic bellows the "soft" support insert could be inter alia a hydraulic, steel or rubber/elastomeric "spring"; the system in its dynamic mode is capable of raising, lowering or leveling the ship hull, or in minutely positioning hull sections to be joined together during construction operations; the system effectively distributes all loads and reactions between the hull and the foundation or ways thereby tending to eliminate unequal elevations of the foundation or way support locations and tending to nullify hull movement effects due to welding stresses and/or temperature changes, thereby tending to provide a constant support system; during moving operations across the foundations or ways, the constant support system will more nearly allow the horizontal pushing force requirements at each support location to equalize; the preferred embodiment of the "soft" support element includes a series of pneumatic bellows units, each unit including a set of three rubber bellows fastened between two opposing plates, the pneumatic pressure in the bellows being variable, system control for the pneumatic pressure can be a simple manual operation or can be highly sophisticated.
