16 Oct 1998TL;DR: In this paper, a Bellows with a plurality of raised circumferential convolutes formed in the surface of the tube is described, with at least one of the convolutes being formed so that a portion of the convolute is substantially even with the surface.
Abstract: A bellows is disclosed which includes a tube having plurality of raised circumferential convolutes formed in the surface of the tube, wherein at least one of the convolutes being formed so that a portion of the convolute is substantially even with the surface of the tube.

TL;DR: In this article, a flexible bellows fits over the spout with the outer end sealingly engaging an inlet (I) of the tank to prevent fuel vapors from escaping into the atmosphere.
Abstract: The fuel dispensing nozzle (10) has a body (12) in which a fuel passage is formed. A spout assembly (18) is attachable to the body in fluid communication therewith for fuel to flow from the body through the spout and into a tank (T). A valve (20) is interposed in the passage and controls fuel flow through the body. A flexible bellows (80) fits over the spout with the outer end (72) thereof sealingly engaging an inlet (I) of the tank to prevent fuel vapors from escaping into the atmosphere. A control apparatus is responsive to movement of the bellows when the spout is inserted into the tank to open the valve, and to removal of the spout from the tank to close the valve. An apparatus (176) is responsive to the vapor pressure within the tank to effect closing of the valve when an overpressure condition occurs thereby to prevent vapor from escaping into the atmosphere. The apparatus includes first and second pivotally connected levers (132, 136) one of which moves in response to movement of the bellows and the other of which moves in response to the vapor pressure reaching a predetermined level indicative of the tank being substantially full to close the valve and prevent vapors from escaping.

TL;DR: In this paper, a first tapered roller bearing (14A) and a second tapered bearing(14B) with a bellows spring and a preload was demonstrated.
Abstract: An assembly includes a first tapered roller bearing (14A) and a second tapered roller bearing (14B) and a bellows spring (20). The bellows spring is disposed adjacent the first tapered roller bearing and the second tapered roller bearing. A method of applying a preload to a first tapered roller bearing and a second tapered roller bearing is also disclosed.

TL;DR: A shock absorbing unit for insertion in a liquid conveying line or a hydraulic accumulator unit comprises a cylindrical outer casing having end walls 21, 22 and a flexible bellows sleeve B connected at its ends to walls 21 and 22 and serving to divide the casing into liquid and compressed gas spaces; the sleeve B having pleats entending throughout its length and which pleats present in an unstressed sleeve a closedcurve sinious cross-section and which lie against each other when the sleeve is contracted as shown in Fig. 3.
Abstract: 1283724 Hydraulic accumulators and surge dampers JOSAM MFG CO 21 Oct 1969 51631/69 Heading F1P A shock absorbing unit for insertion in a liquid conveying line or a hydraulic accumulator unit comprises a cylindrical outer casing having end walls 21, 22 Fig. 1 at least one of which is connected at 24 to the liquid supply line, and a flexible bellows sleeve B connected at its ends to walls 21, 22 and serving to divide the casing into liquid and compressed gas spaces; the sleeve B having pleats entending throughout its length and which pleats present in an unstressed sleeve a closedcurve sinious cross-section and which lie against each other when the sleeve is contracted as shown in Fig. 3. Compressed gas is forced through a plug 25a, into space G and liquid admitted at 24 passes through an orifice 23 in a disc 23a into the sleeve interior. In a modification collapse of the sleeve is limited by a perforated sleeve (29) Fig. 8 (not shown) entending between and secured to the casing end wall. In a further modification a connection (24a) Fig. 12 (not shown) in the other end wall allows the unit to be connected in line with the liquid conveying line as is also shown in Fig. 11 wherein the bellows sleeve B1 is of sinuous form. In a further modification the liquid connection may be closed by a valve having an operating stem entending through both ends cap and within the bellows. In Fig. 14 (not shown) the gas space is within the bellows sleeve.

TL;DR: An internally supported, flexible duct joint for use in conducting fluids under relatively high pressures in systems where relatively large deflection angles must be accommodated is described in this paper, where a flexible tubular bellows and an elongated base disposed within the bellows are connected through radiating struts.
Abstract: An internally supported, flexible duct joint for use in conducting fluids under relatively high pressures in systems where relatively large deflection angles must be accommodated The joint includes a flexible tubular bellows and an elongated base disposed within the bellows The base is connected through radiating struts to the bellows near mid-portion thereof and to each of the opposite end portions of the bellows through a pivotal connecting body A motion-controlling linkage is provided for linking the connecting bodies, whereby angular displacement of the joint is controlled and uniformity in the instantaneous bend radius of the duct is achieved as deflection is imposed thereto
