  • Patent number: 11845120
    Abstract: Bellows are devices used to compensate linear, thermal, or angular movement/expansion. In oil and gas industry bellows are used in gas lift valves as a slidable seal between two gases. Gas lift valves are used in process of oil artificial lift from wells. Bellows having very thin walls are not well suited for pressures higher than approximately 200 PSI. To withstand much higher pressures bellows are being crimped, process that compresses the bellow to shorter length which increases bellow mechanical toughness. This patent application refers to bellow crimping method that uses initially balanced internal and external pressure to crimp bellow to desired length and maintain perfect bellow elements-convolution ? geometry using custom designed crimping device.

  • Patent number: 8431855
    Abstract: The formation of a bellows made up of a stack of a predetermined number of ring-convolutions and having an intermediate plate supported within said stack is achieved by supplying several thin metal rings, each having inner and outer edges. A pair of these metal rings are positioned in contiguous relationship and their adjacent inside edges are welded together to form a ring-convolution. This process is repeated until a sufficient number of ring-convolutions are made to eventually make the desired bellows. Before these separate ring-convolutions are fused to each other, an intermediate plate and a support ring are made. The intermediate plate is a disc of metal that is sized smaller than the inside diameter of the rings and is secured to the support ring. The support ring is then positioned between two formed ring-convolutions in contiguous relationship and the three abutting outside edges are welded to each other to form a support plate convolution.

  • Publication number: 20110219946
    Abstract: A brake actuator having a plurality of actuator housing portions includes a diaphragm seal partially delimiting a parking brake de-actuation chamber and retained between adjacent portions of the housing. To produce brake actuation upon depressurization of the parking brake de-actuation chamber, a push rod extends into and out of a service brake actuation chamber upon release of fluid pressure from and supply of fluid pressure to the chamber. A clip or similar element receivable over the end section of the push rod is securable on the end section to compress the diaphragm seal axially relative to the push rod against a seat carried by the push rod while permitting a radial inner edge of the diaphragm seal to remain spaced from an outer surface of the end section.

  • Publication number: 20100287755
    Abstract: With a method for manufacturing a bendable tube, which is preferably envisaged for an endoscopic instrument, first a tube is separated into several tube sections in a manner such that adjacent tube sections engage into one another with a positive fit in the axis direction of the tube. After the separation of the tube into several tube sections, one envisages peripherally arranging means for providing a positive fit transversely to the axis direction of the tube, on the regions of the tube sections, which are situated in engagement with one another.

  • Patent number: 7712202
    Abstract: A system for securing a basket containing product securely within an autoclave or retort. The preferred embodiment of the present invention is used with rotational retorts, which generally include a rotational insert for receiving product-loaded baskets, the rotational insert rotated via a drive to rotate the baskets end over end during the autoclave process, for more efficient heat transfer. The present invention contemplates an improvement for securing the baskets within the retort, to facilitate secure rotation of the baskets and their contents, and prevent shifting of the baskets within the retort during rotation. Particularly, the preferred embodiment of the present invention contemplates the use of one or more lift bladders sandwiched between clamping platens situated along the length of the rotational insert, the lift bladders configured to expand to lift and position the baskets into a securing position for rotation, then deflate to release the baskets after processing for removal.

  • Patent number: 7685693
    Abstract: The disclosure relates to a method for forming a die having an applicator slot for translating an applicator liquid through the die. The slot is in fluid communication with a die cavity. An expansible chamber device is disposed within the die cavity and changes volume in response to changes in fluid pressure within the expansible chamber device, which may be regulated by a means for controlling the volume of the expansible chamber device. In some embodiments, the die has a single rectangular applicator slot, and the expansible chamber device is an expandable cylindrical tube disposed within the die cavity. In other embodiments, the fluid within the expansible chamber device may be selected to be a compressible gas. In further embodiments, the fluid within the expansible chamber device may be selected to be an incompressible liquid.

    Abstract: A damping element shaped as a cylindrical hollow body having an end-side stop and a wall surrounding the body with annular flanges extending around the wall spaced relative to one another. The annular flanges and the wall between the annular flanges have different thicknesses. A method for producing the damping element, includes first producing a blank of the cylindrical hollow body and subsequently upsetting the body to simultaneous shorten it in the direction of the upsetting force by at least 20% of its original length. Then, the walls of the cylindrical hollow body are convexly arched between the annular flanges to form a bellows-like configuration.
