A device, system, and method for creating a molded crayon body are provided. In embodiments, the device includes a receiving and positioning device having a channel for receiving a wax stick. The channel may be configured to receive and position a wax stick for melting by a melting component. The device may further include a positioning and/or adjustment component that raises and lowers a mold plate with respect to a front surface of the melting component. In some embodiments, the melting component includes a nozzle having a nozzle tip configured to transfer melted portions of the wax stick from the nozzle of the melting component to a mold on a mold plate. The mold component may also include a chilling mechanism for cooling a completed, molded crayon body.

A co-rotating twin screw extruder for forming fragments is disclosed. The extruder comprises of an intake zone for receiving one or more excipient(s) suitable for oral dosage or one or more excipient(s) suitable for oral dosage along with one or more active pharmaceutical ingredient, a melt zone for softening at least one excipient to form a viscous mass or melt and a fragmenting zone for fragmenting and cooling the viscous mass into cooled fragments and an extruder outlet for recovering the cooled fragments from the extruder.
摘要:
A method of supporting a cantilevered component mounted to a hub by locating a cassette in proximity to the cantilevered component, the cassette defining a volume for filling with an encapsulant; filling the volume with an encapsulant material; and causing the encapsulant to solidify to the cantilevered component to support the cantilevered component. The cantilevered component is preferably a blade on a bladed disc and the encapsulant provides support to change the vibration response of the blade during a subsequent machining step.

A color three-dimensional (3D) printing system includes (1) a solid build ink for each of a plurality of colors, each solid build ink includes (a) a solid acrylate in an amount from about 40 to about 70 percent by weight, (b) a non-curable wax in an amount from about 10 to about 45 percent by weight, (c) a curable wax in an amount from about 1 to about 15 percent by weight, (d) a photoinitiator, and (e) a colorant; each solid build ink has a curing speed adjusted by a ratio of the non-curable wax to curable wax such that the initial curing speed and final hardness of each solid build ink is approximately the same for each of the plurality of colors, and (2) a support material includes the non-curable wax used in each build ink, the support material providing a scaffold for deposition of each build ink.
摘要:
A carbon composite contains expanded graphite; and at least one of a filler or a reinforcement; wherein the expanded graphite comprises a plurality of randomly oriented basal planes. Methods of making the carbon composite and articles comprising the carbon composite are also disclosed.
摘要:
The present invention relates to a solid composition that is especially in the form of a product cast as a stick or in acupel, the said composition having an outer surface, and containing one or more magnetic bodies (1) of non-zero magnetic susceptibility, the said solid composition being characterized in that these magnetic bodies (1) are on at least part of the said outer surface non-randomly oriented in the solid composition so as to form on the said outer surface one or more pattern(s) (5).
摘要:
Curled decorative grass having a variety of configurations and methods for making such decorative grass is provided which, because of its increased bulk, can also be used as a packing material, animal bedding, cat litter, mulch for soil, and a media for plants. The curled decorative grass is produced by curling a substantially flat sheet of material and thereafter cutting the resulting curled sheet of material, or by cutting a pre-curled material.
