A system and method for extruding film with a thickened profile section. In some embodiments, the film forms bags with integral zipper profiles. Plastic film is extruded to form a tube. During extrusion, each thickened profile section is radiantly cooled in a preferential manner before thinner sections of the film freeze. A freezing control device includes at least one radiant cooling plate that is operatively aligned with a thickened profile section. The device also includes a cooling fluid recirculation system configured to maintain the plate at a temperature below the temperature of the extruded tube. The plate can be adjustably mounted on a base for positioning the plate at the desired orientation for cooling the thickened profile section of the tube.

A reel based tensioning device includes a housing, a spool that is rotatably positioned within the housing, and a knob member that is operably coupled with the spool to cause the spool to rotate in a first direction within the housing and thereby wind a tension member about the spool. The reel based tensioning device also includes a load holding mechanism that is coupled with the spool and that is configured to rotate the spool in the first direction within the housing and to prevent rotation of the spool in a second direction to prevent unwinding of the tension member from about the spool. The reel based tensioning device further includes an audible component that is configured to produce an audible noise responsive to operation of the knob member to signal an adjustment of the tension member.

A micro fluid filtration system (100) preferably for increasing the concentration of components contained in a fluid sample has a fluid circuitry (1). The fluid circuitry (1) comprises the following elements: A tangential flow filtration element (7) capable for separating the fluid sample into a retentate stream and a permeate stream upon passage of the fluid, an element for pumping (3) for creating and driving a fluid flow through the fluid circuitry (1) and at least one element for obtaining information about the properties of the fluid sample within the circuitry. The circuitry further comprises a plurality of conduits (24) connecting the elements of the fluid circuitry (1) through which a fluid stream of the fluid sample is conducted. The circuitry (1) has a minimal working volume of at most 5 ml, which is the minimal fluid volume retained in the elements and the conduits (24) of the circuitry (1) such that the fluid can be recirculated in the circuitry (1) without pumping air through the circuitry (1). An integrated microfluidic element (20) of the circuitry (1) contains the functionality of at least two elements of the group of elements of the circuitry (1).

Collapsible tunnel systems or segmented tubular structures may be printed on or otherwise attached to base layers on articles of apparel, articles of footwear, or other articles of manufacture. The collapsible tunnel systems have two or more tubular structures attached to the base layer, with tunnels extending through the tubular structures. A tensile strand may be laced through the tunnels in the tubular structure such that when tension is applied to the tensile strand, the tunnels may collapse into a structure with a continuous tunnel through two or more tubular structures. In some embodiments, two or more segmented tubular structures each have two spaced-apart tubular structures joined by a connecting portion, and a tensile strand extending through tunnels in the tubular structures.

A method of forming a printed structure is disclosed. The method may include printing layers of a printed structure and incorporating an element within the printed structure. The element may be removed in order to form tunnels within the printed structure. In some embodiments the element may be removed and reused in the formation of additional printed structures. The element may also be retained to form a composite printed structure.

A cover that extends over a fastener and methods of installing the cover over the fastener. The cover includes an open end positioned at a member from which the fastener extends. The cover also includes a closed end that extends over the fastener and shields the fastener from the exterior environment that can be combustible. The cover includes an outer shell with one or more windows. An inner shell is positioned within the outer shell. The inner shell includes one or more windows that are offset from the windows of the outer shell. One or more flow paths extend through the windows for gas, liquid, and/or some particles to flow through the cover while removing the thermal and/or kinetic energy that may ignite the combustible exterior environment.

Such a molded surface fastener of the present invention has a substantial engaging force with respect to a female surface fastener and can make a texture of its surface comfortable.

A process for making a container includes the step of providing at least one of a slider, sticker, textured surface, pattern, or embossed surface along a folded web of thermoplastic material that comprises a plurality of container templates. The process also includes the step of picking up, with a turner, each container template. The turner includes one or more rotator assemblies that include a rotatable shaft and a bag-contacting surface connected to an end of the rotatable shaft. The bag-contacting surface is configured to engage a top exterior side of each container template. Additionally, the process includes the step of reorienting, with the turner, each container template. The rotatable shaft is configured to horizontally translate and rotate each container template.

A method for molding amorphous polyether ether ketone including steps of preparing a molten mass including polyether ether ketone, cooling a mold assembly to a temperature of at most about 200° F., and injecting the molten mass into the cooled mold assembly.
