Abstract: Sublimation dyeing uses first and second donors, with heat being applied simultaneously from both sides of the object. Receivers can be woven, non-woven, knitted or not knitted, or any combination of these, or any other factors, and are contemplated to include fabrics used for clothing, banners, flags, carpets, wall hangings, and so on. Process parameters use lower temperature and longer dwell times than for one-sided sublimation printing, most preferably dwell times of between 70 seconds and 120 seconds, and a sublimation temperature of less than 400° F. (204.4° C.). Solids and patterns can be reproducibly printed, even in small lots, and can facilitate just in time production of clothing and other materials.

Abstract: A continuous feed discharge surface treater for treating web materials has a discharge chamber where ionization of a process gas occurs defined and contained by one or more rollers. Enhanced chemical coronas and plasmas are achieved by limiting depletion of the gas chemistry from the discharge chamber and dilution or contamination from mixing with drawn in ambient air. Atmospheric coronas can also be achieved in which minimal or no ozone is exhausted from the treater. Various roller and electrode assemblies, including both fixed and rolling electrodes, can be employed.

Abstract: An apparatus for tipping surgical sutures includes a drum around which the suture is wound. The drum is placed on a carriage which moves the drum into a chamber wherein selected portions of the suture are passed through a mist of cyanoacrylate tipping agent generated by ultrasonic atomization. The tipping agent quickly cures and the tipped portion of the suture may be cut to create a tipped end for insertion into a surgical needle to form a needle-suture device.

Abstract: This invention processes a multitude of axially centered samples, materials, and masses, in heat and vapors, all substrates and masses rotating on a multitude of center cores within bellshaped chambers, and around themselves, while each core and each substrate is accessible once during each separate rotation through the chambers for sampling, observation, termination, reinsertion, or substitution.

Abstract: A system for the processing of any substrates, masses, and materials, using a plurality of multifunctional workstations in numerous variations and combinations to obtain a huge range of capabilities for the use of stacking multipliers, gentle internal processing, gravity drives, and free generation of electricity.

Abstract: A method and apparatus for applying dye marks to a line at predetermined fixed increments. An unmarked line is wound around a roller tube which has a slot formed therein communicating with the interior of the roller tube. A vaporized dye is supplied to the interior of the roller tube and exists through the slot and the roller tube. The disperse dye contacts and penetrates the portion of the line overlying the slot to produce a dye mark on the line at predetermined increments equal to the circumference of the roller tube.

Abstract: There is described herein an improved method for decatizing in an autoclave wherein steam is led into the jacket surrounding said autoclave, at a pressure level increasing up to a stationary level within the autoclave. That is obtained by means of an automatically and adjustably controlled throttling valve at the steam inlet to the jacket, the valve being for instance driven by means of a microprocessor routine, and having an autoclave inlet valve associated therewith. In case the outer jacket is missing there might possibly be provided only an automatically controlled autoclave inlet valve performing also as a throttling valve, in order to have a gradually increasing inlet pressure.

Abstract: A discontinuous system applies chemical solutions, dispersions, slurries and pastes to fibrous materials, paper, plastic and metal sheeting, or their composites, confined in one station and capable to wind, rewind and position rolls in sequence and to process sheeting with the ability to interrupt, inspect sections, and add additional windings of the same roll under varied conditions.

Abstract: A machine for spreading and severing cloth from a roll, the machine including an expansible perforated endless belt for conveying the cloth from the roll, a vacuum system for drawing a vacuum through said perforated endless belt, the perforated endless belt having a cloth carrying and return flight, said cloth carrying flight capable of condensing said cloth, and cutter knife means to sever said cloth as desired. The cutter means may be a cutter knife or a cutter hot wire.

Abstract: A continuous system applies chemical solutions to successive rolls of fabric from alternate applicators. The treated rolls pass through a plurality of stations within a common development chamber, emerging fully processed in one continuous movement. Radiant heat and steam are applied throughout the chamber and a winding and rewinding operation provides uniform treatment. An inclined chamber section permits gravity feed of the rolls.

Abstract: Apparatus for applying dyestuffs to textile materials by transfer of the dyestuffs sublimated at reduced pressure, characterized in that it comprises a cooling roll for cooling heated, printed or dyed material to temperatures lower than its secondary transition point and, if desired, further comprises at least one of a pre-heating roll for lessening the temperature gradient between the surface and reverse sides of the textile material to be printed when transfer printing is effected on a heating roll, a brushing roll for remedying deformed, printed textile material and a means for controlling the feeding rates of a transfer printing paper and a backing paper with respect to each other thereby to minimize the difference in peripheral velocity on the heating roll between the printing paper and backing paper.

Abstract: An improved apparatus for batch treatment of textile materials in the form of broad widths is provided in which an enclosure is provided with a closure means at its ends and having provision interiorally for two perforated hemi-cylindrical plates placed concentrically in the lower and upper parts of said enclosure and said plates being movable according to vertical translation; said enclosure preferably being cylindrical and having a ratio of length to diameter of between about 1 and 10:1.

Abstract: Apparatus comprising an inner cylinder and an outer cylinder which are telescoped with respect to one another to define between them an annular treatment chamber in which materials, such as textiles, are treated with a fluid medium. The ends of the annular chamber are closed by radial flanges on one of the cylinders, and clearances are sealed by pressurized seals. Material to be treated is wound onto the inner cylinder, and fluid medium is circulated through the chamber while one cylinder is rotated and the other remains stationary. At the conclusion of treatment, one of the cylinders is moved axially with respect to the other so as to expose the inner cylinder for unloading and reloading. Novel T-shaped seals of rubberlike material are mounted within annular grooves in the cylinder flanges, with the head of the T forming a diaphragm and the leg of the T projecting toward the other cylinder.
