In accordance with principles described herein, portable heated seats, and methods and systems for using the same, are provided that overcome some (or all) of the problems commonly associated with existing seats. These portable heated seats are easily transportable, and are preferably provided with cushion material to compensate for various seating conditions that may otherwise be faced by a user. One or more heating elements, preferably made of flexible graphite felt, are also provided in each portable heated seat. The heat settings of the one or more heating elements are controlled by one or more on/off switches, open loop temperature regulators, pressure push switches, sensor switches, and/or fuse circuits. A backrest (similarly heated or not heated) may also be used in association with the portable heated seat. Various alternative embodiments are also disclosed.

An abrasive element comprises a body of crystalline abrasive material. The body has an array of cutting elements formed of crystalline abrasive material which projects from a surface of the body. The shape, size and form of the projections is controlled in the production process. The body may be a natural or synthetic crystal. The body may be a film formed by deposition. The body may be diamond or cubic boron nitride. The body may be monocrystalline or polycrystalline. The projections may be aligned along a crystallographic plane or planes.

摘要:
A power tool assembly, such as a soldering tool, is provided with a power tool having a functional end, a cap for protecting the functional end of the power tool, a first receiving surface on the power tool at least proximate to the functional end for removably attaching the cap to the power tool to cover the functional end. The power tool also has a second receiving surface on the power tool for removably attaching the cap to the power tool at a surface other than the first receiving surface when the functional end of the power tool is in use.
摘要:
The present invention provides a soldering iron with a graphite tip having two separate halves that are electrically isolated from one another. The tip halves are each electrically connected to the opposite sides of an electrical power source. When both halves of the tip are applied to an electrically conductive material, such as the material to be soldered, an electrical circuit between the tip halves and electrical power source is completed. The halves are of the tip are constructed from material semi-conductive electrically and having high thermal conductivity. Therefore, the tip can reach operating temperatures quickly. When the tip is removed from the joint, the electrical circuit is broken and the tip material may quickly cool to a temperature safe for human contact. Because electricity is only able to flow when the two pieces of the tip are electrically connected, no separate switch is required. The tip material permits higher power outputs than other battery operated portable soldering irons and permits over 300 joints for each full charge. The soldering iron also includes a light disposed on the case to illuminate the tip and joint. However, the light is controlled by a separate switch and permits the tool to be used to illuminate the operator's surroundings without the risk of damage to persons or property from a heated tip. The tool also includes an electrical lead connected in series with the lamp, the power source, and a continuity testing probe. This aspect of the invention permits the tool to function as a continuity tester.
