Patent CA-1058862-A (CA)

Abstract: ABSTRACT OF THE DISCLOSURE          This describes a metal melting furnace consisting of a melt drum lined with refractory material.  Heat is supplied by two burners, one at each end of the melt drum capable of burn-ing oil, gas or powered fuel or any combination of same.  The unique burner creates a rotating flame pattern that expands to the dimension of interior of the drum and/or combustion chamber for complete contact with the molten metal and the melt drum.  The melt drum is capable of partial rotative racking action first in one direction and then the other.  Metal is fed through a charge port in the side wall of the drum each partial revolution and when up to temperature, molten metal may be withdrawn from pouring spouts near the top of the drum each time the drum reaches the end of its travel in either direction.  The complete flame coverage of the drum and/or combustion chamber and molten metal by the rotating flame pattern plus the near constant roll-ing motion of molten metal over three-quarters of the side wall area of the melt drum ensures maximum heat utilization and rapid initial heat.  A feature of the furnace is an annular exhaust flue that directs the exhaust gases passing through the side wall charging port to a vertical outlet, regardless of the rotated position of the charge port.  The furnace exhaust gases are utilized to dry and preheat the incoming metal load and to gener-ate steam to protect the exhaust damper and fuel burners from erosion.  The very dry steam is passed through the burners to the retort.  The furnace body is water cooled.  The heat picked up is absorbed in the air circuit to the fuel burners and re-cycled.

Abstract: ABSTRACT OF THE DISCLOSURE        COUNTERCURRENT PLUG-LIKE FLOW OF TWO SOLIDS               Disclosed is a process for contacting at least two solids and a fluid. More particularly,  disclosed is a process for retorting and/or gasification of solid carbonaceous materials such as coal, coke, shale or tar sands in which a solid heat-transfer material is introduced into an upper portion of a vessel and a solid carbonaceous material is introduced into a lower portion of the vessel. The solid heat carrier is fluidized by an upflowing gas while the solid carbonaceous materials are entrained. The solid heat-transfer material substantially flows downward through the vessel while the solid carbonaceous material flows upward.  If the fluidiz-ing gas is inert, then as the solid carbonaceous material flows upward, it is heated by the downflowing heat transfer material and the volatile or liquefiable hydrocarbons in the solid become part of or are entrained in the fluidizing gas.          If the fluidizing gas is reactive, then the solid is gasified and the solid heat-transfer material is either heated or cooled depending on whether the gasification reaction is endothermic or exothermic.  Substantially countercurrent plug flow of the two solids in the vessel is maintained by including a packing material in the vessel.

Title: Planar insulation of conductive patterns by chemical vapor deposition
Inventor: MADDOCKS FRED S
IPC: H01L21/306
Filed: 1976-12-22
Granted: 1979-05-29
Abstract: ABSTRACT     A method using a chemically vapor deposited (CVD) insulator to form a substantially planar layer of insulative material atop a conductive pattern on the surface of a substrate.  The invention also features the use of a photoresist both as a mask for forming apertures in an underlying insulating layer as well as a lift-off material for a subsequently deposited conductive layer.  In the method, a first insulating layer is deposited atop the substrate.          Photoresist is then deposited; the resist pattern is exposed and developed; and the insulator is etched to expose selected areas of the substrate.  A conductive film, preferably metal, is then deposited in blanket fashion in such quantity as to achieve the same height as the first insulator within the exposed apertures.  The resist is lifted off, thereby leaving metal in the exposed apertures only.  The pattern at this point consists of a single level of a conductive pattern and the insulator pattern with gaps between the conductors and the insulator.  The gaps are the result of the unavoidable removal of a portion of the insulator below the photoresist during the etching process.  Another insulating film is chemically vapor deposited (pyrolytically deposited) in blanket fashion.  Notwithstanding the gaps between the conductors and first insulator, the second film is substantially planar if the thickness of this second insulating film equals or exceeds one-half the width of the largest of said gaps.  The method is applicable to any level of conductive patterns (metallization) atop the substrate.

Abstract: ABSTRACT OF THE DISCLOSURE      A method and apparatus for continuously coating a thread or core with a thermoplastic is disclosed wherein a flowing stream of the plastic, in the form of a melt or liquid monomer is used to convey the core from one or more elongated and heated guide tubes into and through one or more elongated and cooled molding tubes axially aligned with each guide tube whereby the thread or core is automatically centered in the tubes and a uniform outer coating of hardened plastic is applied.  The liquid monomer can be treated with a suitable activator or catalyst before entry into the mold tubes or at an intermediate mixing zone located between the exit part of the guide tubes and the inlet part of the cooling tubes.  The mixing zone is larger in volume than the tubes and provides an off-center convolution about the exit ports of the guide tubes and coaxial conical exit ports converging into the entry ports of the molding tubes.
