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: A method and apparatus are provided for detoxicating, aerating, drying and sterilizing clothing articles. A drying chamber is provided which has an inner chamber in which the clothing articles are to be hung. A first intermediate chamber and a second intermediate chamber are provided in the walls defining the inner chamber through which air is caused to flow. A heater is provided for heating air drawn in from the room and, if preferred, a condenser may be provided for removing moisture from the air after it has passed through the inner chamber. Air may be recirculated within the drying chamber by use of the condenser, or fresh air may flow through the condenser to provide a cooling air stream to the condenser, while heated moist air flows separately through the condenser to remove heat and moisture before the air is exhausted back into the room.

Abstract: A substantially self-contained system and corresponding method provides practical spot cleaning of soiled garments without requiring the use of chlorinated solvents. A soiled garment may optionally be pretreated with either of a water based or petroleum based nonchlorinated cleaner. Thereafter, a relatively high level of vacuum force is applied to the soiled garment to be cleaned, and comprises the flushing agent for both the soil and the pretreatment cleaner. Drying effects obtained with the vacuum force may be augmented by the addition of compressed air directed onto the garment. A self-contained workstation practicing such methodology may optionally include an electric water boiler for generating steam to be applied as a supplement to vacuum and also include an industrial grade vacuum pick-up with a waste collector for generating the relatively high vacuum force, preferably at least about 80 inches of mercury of static pressure.

Abstract: A substantially self-contained system and corresponding method provides practical spot cleaning of soiled garments without requiring the use of chlorinated solvents. A soiled garment may optionally be pretreated with a water base, nonchlorinated cleaner. Thereafter, a relatively high level of vacuum force is applied to the soiled garment to be cleaned while steam is directed onto the spot. The steam comprises the main cleaner when no pretreatment is used, and comprises the flushing agent whenever a water-based pretreatment cleaner is used. Drying effects obtained with the vacuum force may be augmented by the addition of compressed air directed onto the garment. A self-contained workstation practicing such methodology may include an electric water boiler for generating steam and an industrial grade vacuum pick-up with a waste collector for generating the relatively high vacuum force, preferably at least about 80 inches of mercury of static pressure.

Abstract: A process for the continuous permanent decatizing and fixing of textile materials in web form, such as woven, knitted fabrics or the like is described. In the process the textile material is damped to a range of 20 to 100%, and pressed against part of two heatable cylinders. The surface temperature of each heatable cylinder is in excess of 140.degree. C. In a first process step the left side of the textile material is applied to the first heatable cylinder, and in a second process step the right side of the textile material is applied to the second heatable cylinder.

Abstract: A stream of gas is forced through the pores of an object and either the gas itself or a component thereof is electrically activated through partial brush discharge such that reaction products will modify the surface of the pore walls as the gas flows through. The method avoids vacuum deposition methods as well as wet-coating methods and is applicable for either hydrophobizing or hydrophilizing objects and for improving, for example, biochemical activities or compatability of the object with a liquid to be filtered later.

Abstract: In the decatizing apparatus of the present invention the fabric to be treated is fed around a rotatable, heated cylinder between a backing cloth and a tension thrust belt. The presence of the backing cloth between the surface of the cylinder and the fabric prevents the production of an excessive greasy gloss effect on the surface of the fabric closest to the cylinder. A moistening device may be provided to moisten the backing cloth before it passes around the cylinder. A wide variety of decatizing effects can be achieved by adjusting the temperature of the belt and cylinder, the tension of the belt, and the moisture content of the backing cloth and fabric.

Abstract: A strip textile fabric (7) is fixed and dehumidified by passing over a heated drum (1) in contact with a pressure belt (6) on its exposed surface. The pressure belt (6) is preheated and tensioned. As the fabric (7) passes round the periphery of the drum the moisture in the fabric is heated to the point where the steam becomes superheated.

Abstract: An installation includes a spinning machine, a winding machine, a bobbin transporting device transporting the bobbins from the spinning machine to the winding machine, and a tube or sleeve transporting device transporting tubes or sleeves from the winding machine to the spinning machine providing a circulation of wound and unwound tubes or sleeves, the bobbin transporting device including at least one automatic yarn steaming device.

Abstract: A machine for cleaning a fabric workpiece, e.g., a so-called spotting machine, operates with a suction nozzle having a screen on which the workpiece is supported. The machine is portable, its casing containing a combination air blower and vacuum pump for generating the suction, and a water tank and pump assembly that provides water under controlled pressure and volume to an applicator tool whereby such water is applied to the workpiece. The size of the screen is restricted to enhance the suction effect, and the pressure of water to the tool is restricted to prevent the splashing of water and dislodged stain particles by controlling the impact velocity. These factors also ensure rapid withdrawal of the water by the suction nozzle and inhibit spreading of the water in the workpiece beyond the area to which it is applied. This process is aided by the shape of the tool which has a flat face for engaging the workpiece and forming a shield around the orifice from which the water flows.

Abstract: An elongatable endless belt passes around four rollers and, in so doing, passes adjacent to the heated surface of a U-shaped platen which has its edges adjacent to two of the rollers. The surface of the belt which faces the platen is in driving engagement with a film coming from a recording means. One of the noted two rollers is driven faster than the other so that the belt moves the film along the platen surface and leaves one edge of the latter at a higher speed than that at which the belt arrives at the other edge of the platen surface. Therefore, the belt progressively elongates and moves along the film as it is moving the latter along the platen surface.

Abstract: Decatizing apparatus comparison a heated cylinder and a backing cloth applied against the cylinder by means of a thrust belt under high tension. The material to be treated passes between the cylinder and the backing cloth. The cylinder is freely rotatable and is driven by passage of the material, the backing cloth and the thrust belt.

Abstract: Decatizing apparatus comprises a steaming cylinder and a suction cylinder. Respective primary backing cloths are associated with the steaming and suction cylinders to press the fabric to be treated against the cylinders, the tension of each primary backing cloth being adjustable independently of the other backing cloth. An intermediate backing cloth is interposed between each primary backing cloth and the fabric in the zone of the cylinder, and moves over the cylinder with its associated primary backing cloth without slipping. The intermediate backing cloths permit the use of high surface pressures to be applied by the primary backing cloths.

Abstract: A continuous decatizing machine comprises a perforated decatizing cylinder supplied with steam. A fabric web to be decatized is passed around the cylinder and is pressed against the cylinder by means of backing cloths. Pressure is applied to the backing cloths by means of strips which are impermeable to steam.
