| 264504000 | Perforation by differential fluid pressure; or smoothing, scoring, or cutting of green concrete with fluid pressure | 7 |
| 20100171242 | Apparatus and Method for Manufacturing Microneedles - The apparatus comprises a mold assembly including at least one bore therethrough having a cavity therein defining the shape of the finished microneedle shape to be formed therein. The bore has an inlet opening and an exit opening. The apparatus also comprises means for locating the polymer to be formed at one end of the cavity and means for introducing fluid into the inlet opening of said bore and into the cavity. The apparatus also comprises exhaust means communicating with the exit opening of the bore, so that introducing the fluid through the polymer causes the polymer to assume the shape of the cavity and the fluid forms a hollow channel to define a needle-like structure in the polymer as the fluid is exhausted through the cavity and the bore. | 07-08-2010 |
| 20100230866 | PROCESS FOR MAKING AN EMBOSSED WEB - A process for making an embossed web. A precursor web is provided between a forming structure and a static pressure plenum. The forming structure has a plurality of discrete apertures or depressions. Pressure is provided by the static pressure plenum against the precursor web and the forming structure to force the precursor web into the apertures or depressions of forming structure to form the embossed web. The resulting embossed web has a plurality of discrete extended elements. | 09-16-2010 |
| 20100230867 | PROCESS FOR MAKING AN EMBOSSED WEB - A process for making an embossed web. A precursor web is provided between a forming structure and a static pressure plenum. The forming structure has a plurality of discrete protruded elements. Pressure is provided by the static pressure plenum against the precursor web and the forming structure to conform the precursor web to the discrete protruded elements of the forming structure to form the embossed web. The resulting embossed web has a plurality of discrete extended elements having open proximal ends. | 09-16-2010 |
| 20100276847 | Device for Stretch Blow Molding and Method for Producing Preforms - A device for the stretch blowing of plastic containers in a continuous single-stage process, having at least one injection rotor, with injection molds for preforms, which are fed via controlled valves from an extruder head and by way of a melt distributor from a central extruder, wherein the axis of the extruder is placed at least essentially in the axis of the injection pipe, and at least the extruder head and the melt distributor can be permanently and synchronously rotationally driven by the injection rotor. A method where, during the manufacture of each preform in the injection mold, injection molding phases and a compression molding or dwell pressure phase are combined and superimposed. | 11-04-2010 |
| 20110180973 | Method for Making an Outlet Channel - A method for making an outlet channel disposes an air spout on a mold corresponding to an inlet gate or an outlet gate of a shaping cavity of an outlet device. An overflow well is disposed corresponding to the outlet or inlet gates of the outlet device. A plastic material is injected into the shaping cavity until the overflow well is filled. During the hardening happens to a part of the plastic material near the shaping cavity wall, the high-pressure nitrogen or liquid is imparted through the air spout, thereby allowing a certain passage formed with the communicated inlet gate and the outlet gate of a body portion of the outlet device to be structured in the plastic material. The part of the plastic material extruded by the high-pressure nitrogen or liquid enters the overflow well. Cooling the entire mechanism allows the outlet device with a certain-shaped passage to be achieved. Thus, a plastic outlet device with a certain-shaped passage is formed, which renews the traditional forming method to promote the integrity of the injecting product, thereby ensuring the pressure-bearing competence as well as prolonging the using life. | 07-28-2011 |
| 20110193270 | SYSTEMS FOR AND METHODS OF MANUFACTURING MICRO-STRUCTURES - Methods of and devices for making pores, nozzles, and slits are described. In some embodiments, the methods create pattern in the molded substrate by controlling the location and direction of a controlled flow stream through molding plates. The molding plate contains a predefined pattern that is able to be used to create the desired pattern in the molding plate. | 08-11-2011 |
| 20160144562 | METHODS OF MAKING INTERIOR PANELS HAVING INTEGRATED AIRBAG DEPLOYMENT DOORS FOR MOTOR VEHICLES - Methods of making interior panels having integrated airbag deployment doors for motor vehicles are provided. In one example, a method of making an interior panel comprises contacting a molten resin in a molding tool cavity with a plurality of juxtaposed pressurized gas streams to form a series of holes, bubbles, knit lines, or combinations thereof in the molten resin. The molten resin is solidified to form a substrate. The series of holes, bubbles, knit lines, or combinations thereof define a frangible tear seam in the substrate. | 05-26-2016 |
