Abstract: ABSTRACT OF THE DISCLOSURE           A carbon and erosion resistant catalyst is provided for simultaneously converting hydrocarbons with steam and carbon dioxide to produce hydrogen and carbon monoxide while simul-taneously reducing carbon dioxide to carbon monoxide in order to produce a reducing atmosphere. The catalyst consists of a cobalt component on an aluminous support, the aluminous support being aluminum oxide in  the alpha phase and having a surface area of greater than .5 m2/gm. but not greater than 14 m2/gm. This catalyst is sufficiently active to convert the hydrocarbons to hydrogen and carbon  monoxide at a relatively low initial temperature and within a relatively large temperature range and simultaneously reduce carbon dioxide to carbon monoxide in the carbon forming range without appreciable de-position of carbon on the catalyst or without catalyst erosion.

Abstract: ABSTRACT OF THE INVENTION           A method of producing 1,3-bis(2-chloroethyl)-1-nitrosourea (BCNU) by nitrosation of 1,3-bis(2-chloroethyl)-urea utilizing as a nitrosating agent dinitrogen trioxide (N203) in molar excess of theoretical wherein the molar excess of N203 ranges from 10-200% and preferably from 10-20%.  The nitrosation reaction is conventionally carried out in the cold From 0°C to -20°C and a non-aqueous solvent is utilized.  The preferred non-aqueous solvent is of the chlorinated variety; i.e., methylene dichloride.  Other preferred solvents include related halogenated compounds such as ethylene dichloride, nitro-compounds such as nitromethane, acetonitrile, and simple ethers such as ethyl ether.

Abstract: ABSTRACT     A connector for circuits located on different layers of a multilayer printed circuit board through a hole in the board.  The connector is a hollow cylindrical conductor made from a metallic, springy material.  A slit in the conductor and a plurality of sharp teeth located on the outside of the conductor extend the full length thereof.  The conductor has a slightly larger outside diameter than that of the hole.          Consequently, when the connector is forced into the hole, the springback (resiliency) of the connector forces the teeth against the circuits on the printed circuit board thereby providing a positive contact.

Granted: 1979-11-27
Abstract: Abstract of the Disclosure A process for preparing pulp-forming particles comprises adding a solution in an aqueous organic solvent of a thermally stable aromatic nitro-gen-containing polymer selected from aromatic polyamides and nitrogen-containing polyheterocyclic compounds to a precipitant to form a dispersion containing pulp-forming particles of the polymer.  The precipitant consists of water and an amide-type solvent for the polymer present in selected ranges depending on the polymer used.  The pulp-forming particles are heated to 30 to 90°C in the presence of at least 2 parts by weight ofa mixture of aqueous organic solvent and precipitant, per part by weight of the pulp-forming particles. The resulting pulp-forming particles can be formed into synthetic paper by combination with thermally stable staple fibers.  The synthetic paper has superior thermal stability, impregnating ability, texture uniformity and electrical insulation.

A second partial stream of the heat-carrying medium is fed to a secondary degasification zone together with the mixture comprising the dry distillation residue.  Volatile constituents are distilled from the mixture in the mixing zone and the secondary degasification zone and are fed to dust-collecting and condensing means.  Degasified residue is recircu-lated second partial stream fed to the secondary gasification zone to the rate of the first partial stream of the degasified residue, which first partial stream is fed to the mixing zone for the dry distillation of the fuel, is between 0.2:1 and 15:1.      The second partial stream is mixed with the dry distillation residue before the second partial stream is fed to the secondary degasification zone and degasified residue dust is discharged in a particle size of more than 75% below 0.3 mm.

Abstract: ABSTRACT OF THE DISCLOSURE          The invention relates to drill bits and more speci-fically to rook bits for drilling oil wells.  It is of particular value in drilling shales, salt, gypsum and the like.  For a number of years drill bits have been manufac-tured with rotary cone cutters of the milled tooth type. In more recent years it has been the practice to mount har-dened inserts of tungsten carbide in place of the milled teeth.  A milled tooth cutter provides longer teeth and better soft formation penetration than a conventional hardened insert cutter with short insert extension.  It will out faster than the conventional hardened insert cutter in such formations but a milled tooth cutter has a short useful life. as compared with a hardened insert cutter. Up till now, hardened insert cutters have not been produced with long insert extension  due to the difficulty in anchoring the inserts in the cutters.  The present invention provides a rock bit with rotary cone cutters having hardened insert teeth utilizing fewer than the normal number of teeth or of cutters for a given gage hole.  The cone cutter body is of greater diameter and a greater wall thickness for approxi-mately the same axial length, to accommodate a greater insert tooth depth or grip length and permit a proportional increase in extension of the insert from the cutter body to provide greater penetration with fewer insert teeth in contact at a given time.
