Granted: 1990-01-10
Abstract: The method is for metamorphically transforming from a frist shape to a second shape in a video graphics system. The method comprises the steps of identifying elements common to the first and second shapes and identifying a first set of segments of elements in the first shape unrelated to the second shape. Each segment is delimited by a pair of common elements and a second set of segments of elements are identified in the second shape unrelated to the first shape.

Title: Copper clad laminate mfr.
Inventor: KAMADA OSAO
IPC: C25B/
Filed: 1983-11-11
Granted: 1987-05-20
Abstract: Process comprises: (i) introducing rolled copper foil through power supply/guide roller into an electrolyte and passing it between parallel electrodes to form an etched layer on the surface of the foil; (ii) applying adhesive to the etched layer; and (iii) pressing the foil onto a synthetic resin-impregnated substrate to form a copper-clad laminate. The laminate is used as a printed circuit board. By electrochemically etching the foil instead of oxidising strong adhesion is obtd. between the foil and the substrate. The absence of copper oxide particles in the substrate reduces the time required for pattern etching, improving the high frequency response of the resulting circuit.

Title: High temp. reactor - uses radiant heat supplied to porous reactor tube
IPC: B01J/
Filed: 1975-10-06
Granted: 1980-09-10
Abstract: High temp. reactor e.g. for pyrolysis, decomposition and combustion reactions of organic and inorganic cpds. in which all the heat is supplied by radiation coupling comprises a reactor tube of porous refractory material capable of emitting radiant energy. Inert fluid is directed under press. through the porous tube wall to provide a protective blanket for the inside of the reactor tube. Reactants are directed in a predetermined path axially of the reactor tube and confined by the protective blanket within the central part of the tube. A heat shield directs radiant energy from an electric radiant energy source into the reactor tube to coincide with the path of the reactants. Since heat is supplied by radiation coupling the temp. of the reactant stream is independent of the temp. of the walls of the reactor tube. The tube therefore does not have to be made of material capable of withstanding the high temp. to which the reactant stream is subjected. The protective inert fluid blanket isolates the wall of the reactor tube from the reactant stream and prevents clogging by the accumulation of precipitates and deposits.

Abstract: A process for treating final acid obtained in forming a nitrate of a polyhydric alcohol, said final acid comprising a mixture of sulfuric acid, nitric acid, water and said nitrate, said process comprising mixing said final acid with an aromatic nitro compound, allowing said mixture to stratify whereby said nitrate is dissolved into said aromatic nitro compound as one layer and there is another substantially nitrate-free waste acid layer comprising sulfuric acid, nitric acid and water, and separating said layers. Preferably the nitrate is trinitroglycerine and the aromatic nitro compound is dinitrotoluene. The waste acid layer advantageously is partially used to form additional dinitrotoluene and is partially mixed with fresh final acid since its presence serves to stabilize such final acid by preventing any settling out of trinitroglycerine, presumably by the action of the small amount of dinitrotoluene which may be present in said waste acid.
