Disclosed are an electronic candle structure and production method, and wax shell of the electronic candle. The electronic candle, comprising a wax shell, an core system and a lining, the wax shell is formed by directly cooling and solidifying melted wax on the outer surface of the lining, the outer surface of the wax shell is formed by the inner surface of a female mold, and the main body of the core system is fixed in the inner space of the lining. Compared with the prior art, the invention greatly reduces the consumption of raw materials and energy in the production process, shortens the production cycle, improves the production efficiency, and effectively reduces the costs. Moreover, the overall mechanical strength of the product is enhanced to prevent the product from deformation under the long-term use conditions at relatively high environmental temperatures, and improve the durability of the product.

The present disclosure relates to a hot knife having a removable blade or tip that has been specifically designed to perform knife joining operations. The knife is mounted to a quick change tool that connects to the end of a robotic arm.

A candle with an embedded item and methods for manufacturing same are disclosed. A method for manufacturing a candle having an embedded item can include providing a first set of items of a first value and a second set of items of a second value different from the first value, combining the two sets to create a third set, and distributing the items of the third set among a set of candles, one item per candle, where the presence, nature, or value of the item within the candle is obscured. The method can further include selling the candles for a first price, wherein, the presence of the embedded item, the nature of the embedded item, the value of the embedded item, or the value of the embedded item relative to the first price is not known to the purchaser. The embedded item can comprise an object redeemable for a prize.

The disclosure discloses a bionic digestive tract as well as a preparation method and application thereof, belonging to the field of bionic technologies and the field of biological technologies. The bionic digestive tract of the disclosure is prepared by mixing a base material (one or more of silica gel, latex and hydrogel) and auxiliary materials (silicone oil and a curing agent) in a certain mass ratio (the mass ratio of the base material to the silicone oil to the curing agent is 100:(0.5 to 10):(0.5 to 3.5)). The simulation performance of the bionic digestive tract is excellent, has strong consistency with a true human digestive tract in terms of performance, structure and function, can simulate the true states of food, drugs and microorganisms in a digestive system, and has great application prospects in the research process of food and drugs.

The acupressure element includes a base with spiked applicators and an additional layer of low-melting substance, which creates a surface flush with the points of the spiked applicators. The layer hides the points and prevents pain. During a reflexotherapy procedure, the layer of low-melting material melts, either under the influence of human body heat or with the use of external heating. The points of the spiked applicators are gradually released and begin to press on the skin. The pressure on the skin does not occur immediately, allowing to prepare for increased pain later and acclimate accordingly.

According to some aspects, techniques are provided for fabricating sinterable metallic parts through the application of directed energy to a build material. In particular, applying energy to a build material comprising a polymer mixed with a metal powder may cause the polymer to form a cohesive structure with the metal powder. As a result, the polymer acts as a “glue” to produce a metallic green part without local melting of the metal. The green part may subsequently be sintered to remove the polymer and produce a fully dense metal part. Optionally, a step of debinding may also be performed prior to, or simultaneously with, sintering.

Technologies are described for a method of making an encapsulated reactant having a desired shape or size. The method comprises providing solid reactant particles and an encapsulating material. The encapsulating material is heated above its solidification temperature to form a molten, semi-solid, or liquid encapsulating material. The solid reactant particles are added to the molten, semi-solid, or liquid encapsulating material and mixed to disperse the solid reactant particles in the encapsulating material and form a mixture. The mixture may be extruded or formed into the desired shape or size of the encapsulated reactant, or the mixture may be solidified and extruded, granulated, shredded, ground, or pressed into the desired shape or size.

The invention relates to a molding material, consisting of or comprising an organic binder, the organic binder being a wax or comprising a wax; and a filler mixture, the filler mixture comprising or consisting of a mineral filler and a fibrous material, wherein the wax is contained in the molding material in a content of between 3% by weight and 23% by weight, and wherein the mineral filler is contained in the molding material in a content of between 75% by weight and 95% by weight. The invention further relates to a molded part made of such a molding material, a method for producing a molded part, and the use of a molding material for forming a molded part.
