In this device for controlling the temperature of a battery of cylindrically-shaped electrochemical cells placed side by side, heat is conveyed by the flow of a heat-conveying fluid, which flow takes place inside a double wall whose section is in the form of circular arcs interconnected at their ends so that the junction points between the arcs are substantially in alignment. Relief is disposed in a baffle configuration inside the double wall to constrain the fluid to flow parallel to said section, alternately in one direction and then in the opposite direction. The wall is disposed against the battery in such a manner that each of the circular arcs is disposed coaxially against one of the cells.

A combination writing pen and stylus is disclosed. The device has an internal ink cartridge deployable through a hole in the stylus tip. The stylus tip extends from a sleeve that is formed of a conductive elastomeric material. The sleeve extends up a rigid shaft of the device such that it contacts a sufficient ground. The stylus tip may be coated with a protective material that adjusts the coefficient of friction and prevents carbon deposits on the touch screen. A sufficient contact patch is achieved to simulate a human finger so as to overcome false positives from common touch screen logic. This is done by altering tip geometries around an air cavity within the sleeve.

Disclosed is a cotton-free electronic cigarette, a heat-insulating and heat-dissipating component of a vaporizer device of the cotton-free electronic cigarette, and a method for heat insulation and heat dissipation. The heat-insulating and heat-dissipating component consists of a heat insulation sleeve and a vapor flow passage.

The invention relates to a waterborne heat-insulating flame-retardant multifunctional nano coating and a preparation method thereof. The coating consists of the following components in part by weight: 48 to 52 parts of waterborne resin and 30 to 50 parts of nano pigment fillers (nano titanium dioxide, nano titanium dioxide-coated hollow glass microspheres, nano titanium dioxide-coated hollow ceramic microspheres and nano antimony-doped tin dioxide (ATO) particles), size and auxiliary materials such as film-forming additive and coupling agent. The preparation method includes the steps that: the nano fillers and the size are first dipped into the waterborne resin, the auxiliary materials are then sequentially added and stirred, and thereby the heat-insulating flame-retardant multifunctional nano coating is obtained. The processing technique is simple, the component proportion is reasonable, and the prepared coating has the advantages of high heat resistance, high reflectivity, high radiative heat conductivity, certain fire resistance, high-efficient heat insulation, excellent mechanical and chemical properties, environment-friendliness, stain resistance, flame retardance and energy saving.

A composite high temperature insulator (A) includes a planar layer (10) having anisotropic thermal conductivity properties. A second planar layer (12) is formed from a rigid insulation material, such as a carbonized mixture of carbon fibers and a binder. The second layer is coextensive with the first layer and is preferably bonded thereto by a carbonaceous cement (44). When used to insulate a heat source, such as a furnace (50), convective heat is directed back to the source by the reflective surface (16) of the inner, anisotropic layer (10). Heat which enters the anisotropic layer is dissipated evenly through the plane of the layer along a plurality of heat paths defined by a plurality of layers (14) of flexible graphite. Accordingly, heat which reaches the outer, second layer (12) results in fewer hot spots than occur with a conventional rigid insulation material, thereby reducing the total amount of insulation material required to achieve a desired level of thermal insulation.

A process kit is described that resists plasma erosion, preserves the spatial uniformity of plasma properties, reduces particle generation in the chamber, and significantly enhances the lifetime of the process kit. A layer of polymer material covers the top surface of the process kit. The polymer material is fluorocarbon-based and not reactive with the species in the plasma. The polymer material not only protects the process kit from progressive erosion, but also prevents the generation of particles in the chamber. The polymer material has similar permittivity to that of the process kit and therefore maintains the spatial uniformity of plasma properties, e.g., etch rate, near the wafer perimeter. The thickness of the layer is controlled between 0.5 and 1.5 mm such that the difference between its coefficient of thermal expansion and that of the process kit will not cause the layer to peel off the process kit's top surface.

A light-weight fabric for producing outerwear garments suitable for wear on boats, beaches and in other environments in which the wearer may be exposed to rain or water, as well as to cold temperature.

Sandwiched between the skins is a layer of polyester fiberfill which imparts thermal insulation-characteristics to the fabric. Dispersed throughout the fiberfill and imprisoned therein are fine, closed-cell foam plastic beads which impart buoyancy and quick-dry properties to the fabric.
