Abstract:
The invention relates to a method of applying a multi-component glue mixture to objects passing through an applicator station for the application of said glue mixture in a manufacturing line. Waste glue mixture is produced during the application of said glue. The method comprises mixing glue components in a mixer to form said glue mixture. The waste glue mixture is collected in a tank, where it is mixed with a fresh glue component to form a mixture. The mixture of waste glue mixture and fresh component is returned to said mixer. A multi-component glue applicator machine (3) according to the invention comprises storage tanks (4, 6) for glue component, day tanks (17, 18) for said glue components, and mixing apparatus (38, 40, 42) for mixing glue components from said day tanks (17, 18) to form a glue mixture thereof. There is provided a glue applicator device (44). One of said day tanks (17) is provided beneath the glue applicator (44).
Abstract:
Method and apparatus for heating gases cooled by an aftercooler that receives hot gases from a compressor. The method includes the steps of directing at least a portion of said hot gases to means for bypassing the aftercooler, and using the bypass means to direct hot gases to a location that receives cooled gases from the aftercooler. The hot gases are used at the location to heat the cooled gases when ambient temperature is at or below freezing, and are used downstream from the aftercooler when moisture freezes in the aftercooler.
Abstract:
A fluid ejection cartridge for dispensing a bioactive fluid including a first reservoir containing the bioactive fluid and a first fluid ejector fluidically coupled to the first reservoir. The first fluid ejector ejects at least a drop of the bioactive fluid onto the ingestible sheet.
Abstract:
Disclosed is a film-forming method, comprising dispensing from a dispenser nozzle a coating solution, which is prepared by adding a solid component to a solvent and controlled to be spread on the substrate in a predetermined range, onto a target substrate to be processed while relatively moving the dispenser nozzle and the target substrate so as to form a liquid film on the entire surface of the target substrate, and arranging a sucking nozzle above and apart from the target substrate such that the sucking nozzle is not in contact with the surface of the liquid film so as to permit the sucking nozzle to suck the solvent vapor right under the sucking nozzle while moving the sucking nozzle relative to the target substrate, thereby removing the solvent from the liquid film and, thus, forming a coated film.
Abstract:
The present invention has several plausible embodiments. In one embodiment an apparatus for coating a medical device is provided. This apparatus includes a coating chamber, a vibrating structure within the coating chamber the vibrating structure capable of suspending a medical device positioned in the coating chamber, and a coating source, the coating source positioned to introduce coating into the coating chamber. In another embodiment a method of coating a medical device is provided. This method includes moving a medical device into a predetermined coating area, vibrating a structure below the medical device, the vibration of the structure forcing the medical device away from the vibrating structure, and coating at least a portion of the medical device that has moved away from the vibrating structure.
Abstract:
The present invention is a method and device, which is suitable for use in an operating theater just prior to implantation, for selectively applying a medical coating to an implantable medical device, for example a stent. Disclosed is a device for use with a stent deployed on a catheter balloon. The device is configured to apply a medical coating of a desired thickness to the surface of a stent only. This is done by use of a drop-on-demand ink-jet printing system in association with an optical scanning device. The device is further configured so as to, if necessary, apply a plurality of layered coats, each layered coat being of a different coating material, and if appropriate, different thickness. The section of the housing in which the stent is held during the coating procedure is detachable from the housing base. The detachable housing section may be easily cleaned and re-sterilized or simply disposed of.
Abstract:
A method for curtain coating a moving web (8) is described, wherein the total amount of the coating liquids and of the lateral flow liquid, added perpendicular to the lateral extension of the curtain (6), is deposited on the moving web (8) under formation of only a minimally thickened bead, wherein there is no need to separate the lateral flow liquid before impingement on the moving web. The corresponding device incorporates in the edge guides (7) a groove (13) having incorporated, in its surface, channels parallel to the direction of the falling curtain (6). The curtain is stabilized with the lateral flow liquid which is supplied to the groove (13), the real guide surface of the curtain, perpendicular to the lateral extension of the curtain (6).
Abstract:
A method and apparatus for coating the glass envelope and portions of the end caps of fluorescent light tubes in a continuous and sequential manner with a thermo-plastic material. The coating is applied by a cross head extruder through which the light tubes are sequentially fed. A vacuum applied during the coating process promotes direct and intimate contact between the coating and the light tubes. The end caps may be heated prior to coating to ensure adherence of the coating to the end caps and not to the glass envelope. Post-coating processes include cooling the coating, severing individual light tubes from the chain of sequentially coated light tubes, and readying the coated light tubes for packaging. The method is automatic, with the apparatus being automatically controlled by a control unit.
Abstract:
The present invention is a method of and an apparatus for creating a pulsed stream of particles in a carrier means, such as air. A pre-metered stream of particles is accumulated in a pulsing chamber of a pulsing means by interrupting the stream of particles by a separator means, which interrupts the flow for a certain portion of the pulse period. The accumulated particles are then removed from the pulsing means by suction, such as by using an ejector. The invention is further directed to a kit or pack of individual absorbent articles which can be produced using the method and the apparatus.
