A multilayer film includes an outer foam layer and a gas barrier layer. The multilayer film may also include at least one tie layer and at least one inner layer, and can be configured to have various film layer constructions. For example, the multilayer film can be configured as a five-layer, six-layer, or seven-layer films. The multilayer film can provide unique texture, softness, quietness, gas barrier properties, light weight and low cost per volume. Further, one or more layers of the multilayer film can contain a vinyl-bond rich triblock copolymer to provide sound absorbing properties.

A portable pipe threader includes a stand upon which a pipe is supported, a carriage supported by the stand, and a plurality of pipe threading tools coupled to the carriage and selectively operable to perform work on the pipe. The portable pipe threader further includes a drive assembly mounted to the stand including a brushless direct current (DC) motor operable to provide torque to one of the pipe or a selected one of the pipe threading tools to rotate the pipe and the selected one of the pipe threading tools relative to each other, and a battery pack supported by the stand in selective electrical communication with the motor to provide electrical power to the motor.

A method of fabricating a refrigerator cabinet or door includes forming a wrapper and an inner liner. The method further includes forming a vacuum insulated core comprising a permeable core material that is disposed inside an impermeable envelope. A sheet of prefabricated compressible foam material is positioned between the vacuum insulated core between the inner door liner and/or the door wrapper. The prefabricated compressible foam material may be cut from a sheet of foam having substantially uniform thickness prior to fabrication of the refrigerator door. The foam compresses to accommodate differences in spacing between the vacuum insulated core and the door wrapper and/or the door liner.

A handheld wood thread cutting tool with an elongated shank formed with a planar surface and including a first end and a second end with a length substantially longer than its width. The first end has a first wood thread cutting edge aligned substantially in parallel relative to a first vertical plane perpendicular to the planar surface and passing through the length of the elongated shank from the first end to the second end. The second end has a second wood thread cutting edge aligned substantially parallel to a second vertical plane perpendicular to the planar surface and running through the width of the elongated shank from a first side wall to a second side wall. A ball handle is affixed between the first and the second end.

A threading insert includes a top surface, an opposite bottom surface, a side surface connecting the top surface and the bottom surface, and a first tooth. The first tooth has a first cutting edge, the first cutting edge including a first top cutting edge connecting a first leading cutting edge and a first trailing cutting edge. The first cutting edge has an edge roundness and the size of the edge roundness varies along the first cutting edge.

The edge portion includes an upper surface, a side surface, and a land surface. The side surface has a front side surface and a pair of lateral side surfaces. An intersection between the land surface and the front side surface forms a front cutting edge. An intersection between the land surface and each of the pair of lateral side surfaces form a corresponding one of a pair of lateral cutting edges. The edge portion contains 80 vol % or more of diamond. A chip breaker recess is provided between the upper surface and the land surface. The surfaces forming the chip breaker recess include a rake face and a breaker wall surface. The upper surface has a front edge portion opposite to the front cutting edge from the chip breaker recess. A pair of protruding portions are provided to extend from the front edge portion toward the front cutting edge.

A cutting element for a tool to create a helically extending, trapezoidally undercut groove in a cylindrical surface of a bore. The cutting tool, preferably configured as a cutting insert, has groove-cutting teeth to create a symmetrically cross-sectioned groove which are arranged in series in a division harmonized with the pitch of the groove to be created. These groove-cutting teeth comprise at least one pre-machining tooth to create and machine a base groove and several trapezoidal teeth following the at least one pre-machining tooth, which have a tooth head profile which expands trapezoidally in cross-section in the vertical direction of the tooth with two flanks delimiting a flank angle for further machining the base groove to a trapezoidally undercut final cross-section. The flank angle delimited by the two flanks increases from at least one trapezoidal tooth to a following trapezoidal tooth to a defined final dimension.

A cutting tool for forming a finished part from a rotating workpiece includes a first cutting edge extending from a first end of the cutting tool, a second cutting edge extending from a second end of the cutting tool, and a shaping edge disposed between the first cutting edge and the second cutting edge. The first cutting edge is operable to remove a trailing end of the rotating workpiece and the second cutting edge is operable to remove a working portion of the rotating workpiece disposed between the trailing end and a leading end. The shaping edge is operable to shape the working portion of the rotating workpiece by advancing the cutting tool into the rotating workpiece until the first cutting edge removes the trailing end of the rotating workpiece and the second cutting edge removes the working portion of the rotating workpiece to form the finished part.
