Abstract: An orally administrable therapeutic protein is provided by combining the therapeutic protein with a stabilizing agent in an aqueous solution. The solution is coated onto nonpareils and microencapsulated with a water emulsifiable enteric coating composition. The microcapsules are orally administered. The coating protects the protein as it passes through the stomach. Upon reaching the small intestines, the basic pH of the intestinal juices will dissolve the coating, allowing the protein to be released and induce antigen specific immune response which has the specificity of the native molecule. The stabilizing agent protects the therapeutic protein from denaturation during the encapsulation process. In addition to being immunogenic, when administered orally, encapsulated allergen has a therapeutic effect in the treatment of human allergies.

Abstract: A plasma processing system for sputter etching a substrate with reduced particle contamination comprises a plasma processing chamber having an interior surface which defines a processing space containing a substrate. An electrical element couples electrical energy into a portion of the processing space to generate a plasma therein for etching the substrate. A heating device is coupled to the reactor and is operable for controllably heating the processing chamber interior surface to a selected temperature. The heating device is controlled by a temperature control circuit which turns the heating device to an ON state and operates the heating device to heat the processing chamber to a selected temperature when the electrical element is not coupling energy to the processing chamber and the plasma is extinguished.

Abstract: Corrosion resistant instruments such as those used in medicine and dentistry are efficiently made from raw materials that are difficult to machine. Round bar stock is rolled or otherwise deformed to have flat sides and rounded edges. The parts of the instrument are cut from the flattened bar, by combinations of transverse and longitudinal cuts, so that the rounded edges of the bar define the shape of convexly curved finish surfaces of the instrument. Expensive machining steps are eliminated. An orthodontic pliers is particularly disclosed, made according to the method, by making one or more Z-shaped cuts that preserve the rounded sides to define the outer surfaces of a handle and opposing jaw on each of two plier parts, pivotally joined together.

Abstract: A water based dredge includes a grizzly with a sieve and a pair of bi-directional rakes. The rakes translate relative to the stationary sieve to slide waste or recoverable material off of the grid and onto a refuse barge or material processing apparatus, respectively. A grab deposits dredge material onto the sieve and an operator determines whether the material includes waste such as clay or the like or recoverable material such as rocks, dirt, or sand. If the operator determines that the dredge material is waste, the rakes will be actuated for movement from a first direction to thereby push the waste off of the grizzly and onto a refuse barge. If the operator determines that the dredge material includes recoverable material, the rakes will be operated in a second direction so the recoverable material is slid from the grizzly and into a crusher or other appropriate processing apparatus.

Abstract: A semiconductor device having tungsten strapped gate electrodes and source/drain regions and a polysilicon resistor. The gate electrodes and the polysilicon resistors are all formed from the same layer of polysilicon by initially coating the deposited polysilicon layer with an insulating layer and subsequently a layer of phosphorus doped silicon glass. The electrodes and resistor areas are formed by selectively etching the silicon glass and the polysilicon. This leaves the electrode polysilicon and the resistor polysilicon coated with the phosphorous doped glass. Spacers are then provided along the electrode and the glass removed only from above the gate electrode polysilicon leaving the resistor coated with the phosphorus doped silicon glass and silicon nitride. Tungsten then can be selectively deposited upon the gate electrode and along adjacent source and drain regions.

The suppressor circuit includes an inductive element electrically connected in parallel with a rectifying element. An anode of the rectifying element is coupled to the negative output terminal of the DC power supply such that during a random fluctuation in sputtering current level at the output of the power supply, attributable to random electrical noise and arcing conditions in the sputtering plasma inside the chamber, the rectifying element is negatively biased and is generally non-conductive and the inductive element stores current energy from the sputtering current level fluctuation.

Abstract: Objects which have been abraded are coated with a coating material which is normally solid at room temperatures. The material is liquified at elevated temperatures and sprayed onto the cooler objects in a heated cabinet, whereupon the material at least partially solidifies on the object. Thereafter, heat is applied to the coating material to cause it to flow out over the coat surface. A cooled conveyor system prevents disruption of the coating material. Overspray is maintained in liquified form within the cabinet where it is reclaimed and flows to a heated sump for direct recirculation to the spray apparatus. There are no deleterious solvent emissions. Apparatus and methods are provided.

Abstract: Ultra high purity materials, particularly metallic materials such as magnesium and similarly high volatility materials, are produced by a vacuum distillation method and apparatus to increase purity by approximately five hundred times in a single step. For example, magnesium purity, exclusive of zinc content, is increased from 99.95% to greater than 99.9999%.
