Title: Views for software atomization
Inventor: HOSTETTER MATHEW J
IPC: G06F17/30
Filed: 2003-06-18
Abstract: Views for software atomization provide runtime transformations of existing atoms in atom databases to create new or virtual atom databases. Views provide for sharing of code and data atoms that are stored in an atom database, as well as providing sharing of code and data atoms that are loaded into memory.  A view is a set of transformation operations, including insert a new atom, modify an existing atom, or delete an existing atom, which can be applied to an atom database. The transformation operations can be applied, either literally, to create a new atom database on disk, or virtually, to create, at runtime, a virtual atom database, without actually having to create an actual atom database on disk. Modifying an existing atom can be done in a variety of ways, including changing the atom bytes, or the atom references, or an attribute of the atom.

Abstract: Described is radiation sensitive imaging and dosimeter composition (20) containing a radiation sensitive material (21), e.g., a diacetylene (R-C=C-C=C-R', where R and R' are substituent groups) or a radiochromic dye, a polymeric binder (22) and optionally a solvent (23) and/or an activator (24). Radiation sensitive materials are incorporated into a moldable or castable material and are molded or casted into shaped-articles (100), such as coatings, films, fiber, plaques, rods and blocks. Upon exposure to high-energy radiations, radiation sentitive material develops color thereby producing a visible image.  Because of the higher thickness, a significantly lower dose of radiation can be monitored and an image is produced in three dimensions. Materials, processes and usages for thick radiation sensitive devices are described. A  thick block can be used for monitoring radiation dosages in the three dimensions.

Title: Batchwise working-up recycling materials in a rotatable reactor
Inventor: SANDBERG OLOF
IPC: C22B19/30
Filed: 2005-05-17
Abstract: A process for batchwise working-up valuable metals containing recycling materials having a content of organic constituents so high that its use as smelting materials in conventional metal smelting processes is not suitably or even possible. The material is charged to a tiltable reactor rotatable along its own longitudinal axis having a common opening for charging and emptying. The material is heated to a temperature promoting the expulsion of organic constituents by pyrolys and/or combustion. The material consists at least to a substantial part of such size fractions that admits a continuous charging during operation. In the process, said material during operation is charged continuously in an adjustable stream being controlled and/or adjusted by means of running measurements of different process variables so that the flow and composition of the combustible gas and the heat release is kept under control. A worked-up product substantially free from any organic substance is withdrawn from the reactor and is added to a conventional metal smelting process. The material is suitably supplied during operation by means of a charging equipment provided against or down through the single opening of the reactor by means of gravity and/or a pneumatic transport gas.
