Abstract: A method and system for the controlled application of fluid pressure of a load, such as a large pipe to be pressure t sted utilized small pressure converters which are operated by a common controller at the hydraulic side to fill and pressurize the pipe. One pressure converter is decelerated as it approaches th end of its working stroke while the other pressure converter is accelerated so that the total displacement of the pressurizing fluid remains substantially constant over time.

Abstract: A sealing arrangement around an end of a pipe received in a testhead of a hydraulic pipe testing apparatus, which sealing arrangement consists of an elastic sealing ring and an adjacent, rigid support ring of varying diameters. Both rings are mounted in radial recesses in the testhead and encircle the pipe upon its entry into the testhead. The recess for the elastic sealing ring consists of a flat ring located between the sealing ring and the rigid support ring. For a sealing condition, the support ring is contracted to abut the pipe and the sealing ring is caused to be deformed whereby it flows radially outwardly from its recess against the pipe and axially along the pipe towards and away from the pipe's end. In the axial direction away from the end of the pipe, the sealing ring flows around the flat ring to abut the rigid support ring.

Abstract: A dye-containing foam is applied to a textile to create patterns thereon. The foam is transferred to the textile in the form of parallel lanes or strips. The lanes of foam are formed on an endless belt which then merges with the textile at a nip to effect the transfer of the dye. The lanes of foam are bordered by parallel partitions which are adjustable to vary the exiting width of the foam. A vertically adjustable doctor blade in each lane governs the height of each lane of foam. An agent for promoting the disintegration of the foam is applied to the side of the textile opposite the side to which the foam is applied, to assure a more uniform application of dye in the direction of the depth of the textile.

Abstract: A device for subjecting web-shaped textile material to a wet pre-treatment in a damper while passing the textile material along a zig-zag path over rollers alternatingly pertaining to one of two substantially parallel vertical rows of rollers, and through a take off or plaiting device. The dry or squeeze-wet textile material is passed through a vacuum and directly subsequently thereto through a treatment bath. Thereupon, the thus treated textile material is withdrawn from the treatment bath and is passed into a damper where it is plaited for from 8 to 20 minutes (abgetafelt).

Abstract: A method and apparatus for wet treatment, especially treating with lye solution and mercerizing, of knitted tubular goods. According to the method, the tube is passed through the space between adjacent rollers. A longitudinal movement is imparted to one of the two respectively straight portions of the cross section of the tube, while a transverse movement is imparted to the other straight section. The apparatus for carrying out this method is a foulard having driven rollers, at least some of which are constantly movable in an axial direction, which is transverse to the longitudinal movement of the tube, successive axially movable rollers having a progressively delayed axial movement.

Abstract: A device for wet treating, especially dyeing and impregnating, a textile web in a continuous manner, which comprises a liquid receiving and containing vat and a deviating drum or roller immersing into the vat and adapted to have looped around its respective lower section the textile web to be treated. The deviating roller or drum is hollow and free from axle journals. Above the respective upper circumferential section of the deviating roller and symmetrically arranged with regard to the longitudinal central plane of the deviating roller there are rolls engaged by the deviating roller in the floating working position of the deviating roller.

Abstract: An apparatus for continuous full-width washing of a textile cloth layer, which is guided horizontally or nearly horizontally between reversing rollers arranged in two vertical rows so as to form horizontal cloth layer sections between respective rollers of the two rows of rollers. The upper side of a given horizontal cloth layer section is supplied with a washing liquor film. Devices are arranged between the vertical rows of rollers for imparting vertical or nearly vertical vibrations to the respective horizontal cloth layer sections.

Abstract: A device for printing in a continuous manner upon a web of textile material by sublimation of the dyestuff of a dyestuff carrier which is pressed against the web of textile material and which during the printing operation is by a pressure belt pressed into engagement with a heated surface of a drum over which the dyestuff carrier passes. The pressure belt is permeable to air and other gaseous substances whereas the heated engaging surface of the drum or the dyestuff carrier is air or gas impermeable.According to a particularly advantageous embodiment of the above mentioned device that region of the pressure belt which is in heating contact with the drum is in communication with a vacuum or is under atmospheric pressure.

Abstract: Apparatus for printing upon webs of textile material by sublimation of the dye of a web of printing foil covering the web of textile material. The apparatus includes a rotatable cylinder having looped therearound the web of textile material, the web of printing foil, and a pressing-on or transporting belt. The apparatus furthermore includes a vacuum chamber adapted to be connected to a source of vacuum, and also includes a heating device. The vacuum chamber is defined by a vacuum cap which sealingly engages sections of the cylinder and the pressing-on or transporting belt.

Abstract: A sealing arrangement for use at the inlet and outlet of containers in which a pressure above or below atmospheric pressure prevails, especially for treating webs of textile material. The sealing arrangement comprises two endless belts respectively looped around two pairs of reversing rollers with the rollers of each pair spaced from each other so that straight belt sections are formed between the rollers of each pair of reversing rollers. The web of goods is passed between two adjacent straight belt sections, which respectively pertain to the two endless belts, and rim portions, and which seal the space surrounded by the belts and located between the rollers against the pressure surrounding the container.

Abstract: A roller sealing head for overpressure and underpressure containers, especially for processing webs of textile and synthetic material with non-fixed application of print or dye or for non-treated webs of goods, in which a first sealing roller has a second sealing roller arranged opposite and in spaced relationship thereto while two endless sealing strips held in a rim-shaped frame are respectively associated with the first and second sealing rollers. The roller sealing head furthermore includes a hollow roller of a narrower width than that of the first and second sealing rollers. The arrangement is such that the web of goods to be processed is directly passed through between the hollow roller and one of the first and second rollers, while only one straight section of each endless sealing strip engages the inside of the hollow roller whereas the curved sections of the sealing strips as well as the second straight section of each sealing strip engages the sealing rollers.

Abstract: The invention relates to a novel process for continuous washing of a textile web in flattened condition by guiding the web along a zig-zag-shaped path over a plurality of guide rolls arranged in two vertical parallel rows in a vessel, while maintaining in said vessel a temperature of at least 100.degree. C and an over-pressure of at least 1 atm., and while subjecting at least one side of the substantially horizontal sections of the web between successive guide rolls to spraying with a wash solution. The invention also includes the apparatus in which said process is carried out.
