  • Patent number: 10165868
    Abstract: An internal tensioning structure for use in an inflatable product fulfills the basic function of maintaining two adjacent inflatable surfaces in a desired geometric arrangement when the inflatable product is pressurized. The tensioning structure is formed by connecting a pair of plastic strips sheets via spaced-apart strands, such as strings or wires. When pulled taut, the strands provide a high tensile strength between the two opposed plastic strips. At the same time, the plastic strips facilitate a strong, long-lasting weld between the tensioning structure and the inflatable product.

  • Patent number: 9199294
    Abstract: A corrugating unit is used which presses a first corrugation into the pipe which is moved in its longitudinal direction through the corrugating device. The spacing between the wave peaks is subsequently reduced, for obtaining a second corrugation, by a clamping unit composed of two separately arranged clamping devices resting against the pipe. The pipe provided with a first corrugation is pressed continuously by the first clamping device against a fixed point realized by the second clamping device, which, in the position of operation, is arranged, in relation to the clamping device, in axial direction behind the first clamping device. Both clamping devices are removed cyclically from the pipe and are moved back into a new position in the opposite direction of the direction of movement of the pipe and, in this new position, again rest in the two different areas against the pipe.

  • 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.

  • 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.

    Abstract: Self purging expansion joint can include first annular seal sleeve connecting bellows to first conduit and second annular seal sleeve connecting bellows to second conduit. Flow-restricting orifice(s) can allow a higher pressure external fluid to flow through the annular passage to purge the bellows and into the primary fluid flow passage of the expansion joint containing a lower pressure fluid. Self purging expansion joint can be utilized in a disengager vessel of a fluid catalytic cracking (FCC) unit, for example, between primary and secondary stripping cyclones.

  • Patent number: 7441810
    Abstract: A sewer line coupling device to facilitate attachment of a recreational vehicle sewer line to a fixed waste pipe. The coupling device comprising a main body having a second end for insertion into the waste pipe. A movable member is movable relative to the main body and a sealing sleeve is supported by the main body adjacent the second end. One end of the sealing sleeve is affixed to the main body while the other end is coupled to the movable member. When the movable member is moved in a first direction, a minimum dimension of the sealing sleeve is achieved to facilitate insertion into the waste pipe and, when the movable member is moved in an opposite direction, a maximum dimension of the sealing sleeve is achieved to facilitate formation of a seal with the waste pipe. A flange is supported by the main body between the first end and the second end thereof.

    Abstract: Traditional structured-containers have a maximum holding capacity upon exceeding of which would allow excess articles fall out of the structured-container by way of gravitational pull. The utility of these structured-containers is thus limited. The present invention discloses an expandable container with a pair of carry-handles where a net container is coupled to a traditional structured-container to thus synergistically and substantially increase the maximum holding capacity of the traditional structured-container. The pair of carry-handles also adds carrying possibilities and conveniences.

  • Patent number: 6865799
    Abstract: A method of manufacturing strain-detecting devices is provided. First, plural cylindrical substrates, each of which has one end closed by a diaphragm, are fixedly placed at predetermined positions of a fixing plate. A positioning marker is previously given to the fixing plate. The fixing plate having the substrates is then assembled into a jig. The jig sustains the substrates so that an outer surface of the diaphragm of each substrate is held at the same level. Through positioning the substrates, all the diaphragms are then positioned in place in a plane direction of the fixing plate with reference to the positioning marker. A strain gage portion is simultaneously formed on each of all the diaphragms. The fixing plate is then disassembled from the jig. In this step, the substrates with the strain gage portions, i.e., strain-detecting devices, are separated from the fixing plate.

  • Patent number: 6820317
    Abstract: In a method of fabricating a bellows by bulge forming, an annealing step is carried out during the bulge forming process of the bellows so that the capability of the material to elongate is recovered, and the workability of the bellows is improved in effect. In particular, the ratio of the outer diameter to the inner diameter can be made greater than a value that can be achieved by a single forming step. Therefore, the deflection (stroke) of each annular bulge or pleat can be increased for a given stress or the number of annular bulges and the length of the bellows can be decreased for a given stroke of the bellows.
