TL;DR: In this paper, a mobile soil-disinfecting device consisting of a cultivating unit (20), a soil treating chamber (23), a bellows (28), a heat exchanger (56), and a heat generating unit (26) was used for breaking the soil and throwing it upwardly into the treating chamber.
Abstract: A mobile soil-disinfecting device (10) comprising a cultivating unit (20), a soil treating chamber (23), a bellows (28), a heat exchanger (56), and a heat-generating unit (26) The cultivating unit (20) comprises one or more cultivating members adapted for breaking the soil and throwing it upwardly into the soil treating chamber (23), and the heat exchanger (56) being in thermal communication with the heat generating unit (26), the bellows (28) adapted for drawing ambient air, passing the air through the heat exchanger (56) and throwing hot air into the soil treating chamber (23)

TL;DR: In this paper, an air spring device having a free-standing air spring bellows and an outer guide which is fastened to the air spring by means of an inner clamping ring was described.
Abstract: The invention relates to an air spring device having a free-standing air spring bellows and an outer guide which is fastened to the air spring bellows by means of an inner clamping ring, wherein the outer diameter of the inner clamping ring is greater than the outer diameter of the air spring bellows in the unpressurized state, and the inner clamping ring generates a radially outwardly pointing encircling bulge in the unpressurized air spring bellows

TL;DR: An expandable and collapsible belt-strap container for carrying sports cards on a person is described in this article, where a cover is attached to the bottom of the inner side of the container.
Abstract: An expandable and collapsible belt-strap container for conveniently carrying sports cards on a person comprises a container (10) having an inner side attached to the mid-portion (14) of a belt (12) by elastic webbings (13 and 13'). The container comprises an expandable and collapsible bellows (11) with an open top, and a flap (18) hingeably attached to an outer side of the container. The flap stretches across the open top and down the inner side of the bellows. A long piece of hook-and-loop fastener (19) is attached to the inner side of the bellows, while a short piece of hook-and-loop fastener (20) is attached to the distal side of the flap. Therefore, when the bellows is fully collapsed, the distal side of the flap may be attached to the lower side of the long fastener. When the bellows is fully expanded for carrying a large number of sports cards, the side of the flap may be attached to the upper side of the long fastener. Because the flap is attached to the bottom of the inner side of the container, it will stay in an opened position when swung outwardly. The bellows comprises a plurality of pleats, each having long and short sections, and sides and a bottom which are attached by curved comers, such that each pleat will be bistable (expanded or collapsed). The container, covering flap, and belt can all be separated or attached together.

04 Mar 1971TL;DR: In this article, a bellows type mechanical fluid seal combination including a first sealing ring structure having an annular sealing face adapted for mounting to a stationary member, a second sealing ring ring structure with a complementary annular face adapted to a rotatable member, and an axially extendible cylindrical bellows structure included with one of the sealing ring structures and cooperating to urge the sealing faces into sealing relationship responsive to applied fluid pressure.
Abstract: A bellows type mechanical fluid seal combination including a first sealing ring structure having an annular sealing face adapted for mounting to a stationary member, a second sealing ring structure having a complementary annular sealing face adapted for mounting to a rotatable member, and an axially extendible cylindrical bellows structure included with one of the sealing ring structures and cooperating to urge the sealing faces of the sealing rings into sealing relationship responsive to applied fluid pressure. The improvement resides in the relative shape and configuration provided for one of the sealing ring structures to attain improved utilization of sealing face areas within a seal installation space of limited dimensions.

23 May 1991TL;DR: A variable-geometry duct with at least one moveable side wall, and a bellows interposed between the side wall and a back-up structure, is considered in this article.
Abstract: A variable-geometry duct having at least one moveable side wall, and a bellows interposed between the side wall and a back-up structure. The bellows creates a sealed cavity between the moveable side wall of the duct and the back-up structure. Pressurized fluid in the cavity is controlled so as to maintain a desired pressure differential between it and the pressure of the fluid carried by the conduit for all positions of the moveable side wall.
