  • Publication number: 20140170360
    Abstract: A reusable and replaceable tool label has a thin rigid body, an adhesive coating, and a removable liner. The thin rigid body is built from first face and a second face, which are connected by a lateral surface. The first face is a writable surface, and is used to record measurements, notes, and other information to the label. The second face allows the label to be attached to tools and other surface, by means of the adhesive coating that is placed on the second face. To prevent the label from sticking to a surface during packaging, transport, and storage, a removable liner is placed over the adhesive coating. The removable liner has a linear cut that makes the removable liner easier to grab. A tab may be connected to the removable linear to make peeling the removable liner away from the adhesive coating even easier.

  • Patent number: 8715582
    Abstract: An apparatus for providing activated carbon that has a reactor vessel for containing carbon based feedstock and a processor that encloses the reactor vessel. An insulating barrier is disposed between the reactor vessel and the processor for defining generally vertical outer and inner pathways that are communicably interconnected. The reactor vessel has a gas receiving intake port in communication with the inner pathway. First and second inlet conduits are formed through the processor and into the reactor for respectively introducing a first ignition gas into the reactor to ignite the feedstock and a second gas into the first pathway. The second gas circulates through the outer and inner pathways and enters the reactor vessel through the gas receiving intake port. The exhaust gas is circulated through a catalyst chamber/cartridge/bed. At least one exhaust port discharges gas from the vessel exteriorly of the processor.

  • Patent number: 8161432
    Abstract: A system for generating processor hardware supports a language for significant extensions to the processor instruction set, where the designer specifies only the semantics of the new instructions and the system generates other logic. The extension language provides for the addition of processor state, including register files, and instructions that operate on that state. The language also provides for new data types to be added to the compiler to represent the state added. It allows separate specification of reference semantics and instruction implementation, and uses this to automate design verification. In addition, the system generates formatted instruction set documentation from the language specification.
