A honeycomb ceramic substrate, a method of making thereof, and a honeycomb extrusion die configured to extrude a honeycomb ceramic substrate from a batch of ceramic or ceramic-forming material is provided. The substrate may include a lattice of intersecting walls defining a honeycomb network of flow channels extending between an inlet end and an outlet end of the honeycomb substrate. Each flow channel may be defined by a plurality of channel walls of the intersecting walls with at least two of the plurality of channel walls including concave inner surfaces facing a center of the corresponding flow channel from central portions of the concave inner surfaces to concave corner portions facing the center of the corresponding flow channel.

According to one embodiment, a nozzle head includes a main body and a plurality of nozzles. The main body has a space in an interior of the main body. The space is capable of storing a source material liquid. The plurality of nozzles are conductive, are connected to the main body, and eject the source material liquid stored in the interior of the main body. An external dimension of one of the nozzles in a direction orthogonal to an extension direction of the nozzle is different from the external dimension of another one of the nozzles in the direction orthogonal to the extension direction of the nozzle.

A die plate is provided for an underwater pelletizer. The die plate includes a die plate body and a solid face plate. The downstream face of the die plate body has a plurality of insulation holes drilled therein that reduce the surface area contact between the die plate body and the solid face plate that is secured to the downstream face of the die plate body to form the cutting surface. In addition, a circular groove is preferably milled into the downstream face of the die plate body. The groove is concentric with the outer perimeter of the die plate body and creates an outer ring and a center boss. The outer downstream surface of the boss is flush with the outer downstream surface of the outer ring so that the boss and ring together form the downstream face of the die plate body for supporting the solid face plate. The insulation holes and groove are filled with a non-reactive atmosphere such as nitrogen, inert gas(es), a vacuum or a partial vacuum.

The present invention is directed at a relatively high modulus spunbond nonwoven material that is suitable for use in relatively high deep draw molding applications.

The present invention relates to a polymer resin composition including: a vinylidene fluoride-based polymer resin; and one or more types of nucleating agents selected from the group consisting of an organic phosphate and a C.sub.5-C.sub.15 bicycloalkane substituted with one or more carboxylic acid metal salt functional groups, and a polymer resin molded product prepared using the polymer resin composition.

A sheath flow system having a channel with at least one fluid transporting structure located in the top and bottom surfaces situated so as to transport the sheath fluid laterally across the channel to provide sheath fluid fully surrounding the core solution. At the point of introduction into the channel, the sheath fluid and core solutions flow side by side within the channel or the core solution may be bounded on either side by the sheath fluid. The system is functional over a broad channel size range and with liquids of high or low viscosity. The design can be readily incorporated into microfluidic chips without the need for special manufacturing protocols. Uses include extruding materials and/or fabricating structures.

The method and system produces a high-moisture aquatic feed that is stable in water and has a texture that more closely resembles naturally-occurring aquatic feedstocks. The system includes a tempering unit that is structured to allow an operator to control the temperature of a low-carbohydrate high-moisture extrudate after the extrudate leaves a conventional extruder. As the extrudate flows through a tubular matrix within the tempering unit, expansion of the extrudate is controlled to produce the high-moisture water-stable aquafeed.

The present invention provides a nozzle plate and the use of the nozzle plate for producing filaments, preferably silica gel fibers.

A reinforced cable tie generally includes an elongate strap having a first end, a second end and an elongate planar strap body therebetween, a head having an upstanding central wall separating a first and a second elongate parallel passageway through the head for respective receipt of the first and second ends of said strap, a locking device supported in the head for retaining the first and second ends of the strap and a continuous reinforcement disposed in and extending substantially continuously along a path defining the strap. In a method for forming a cable tie, a continuous reinforcing strand is co-extruded within an elongate strap and a head is assembled to the strap.

In various embodiments, a device for producing a high density compact livestock feed from a loose granular material according to various embodiment can include a source for supplying a loose granular material to be treated and moving the treated material through a series of successive treatment zones. Rotatable screws are provided within an extruder to compress and transport the treated material a die. The treated material is pressed through the die while a two-dimensional cross-section compression is applied to the treated material. In various embodiments, the high density compact livestock feed is produced having a high protein content, a high fat content, high shipping durability, high quality, and high nutritional value, without the addition of additives.
