Abstract: ABSTRACT           A highly reactive carbonaceous material is disclosed which comprises at least 0.5 weight percent of a ferrous group metal component bonded to the carbon in the material. Also disclosed are processes for manufacture of this carbonaceous material and processes for using it to manufacture methane. The carbonaceous material may be in two forms, unpromoted carbonaceous material and hydrogen promoted carbonaceous material. The unpromoted material is formed by contacting a carbon monoxide-containing gas with a ferrous group metal carbon monoxide disproportionation initiator under conditions where the required amount of ferrous group metals diffuse into and bond at least partly to free carbon depositing on the bulk ferrous group metal initiator. The hydrogenated promoted material is formed by contacting the unpromoted material with hydrogen.  The source of the carbon monoxide may be a producer gas derived from burning coal.  our material includes the free carbon as a continuous major phase and one or more ferrous group metals, metal alloys, or metal carbides associated with and bonded to the free carbon as dispersed minor phases.

Abstract: Case 3879 INTEGRALLY FORMED RESILIENT CLIP AND EXTENSION     ABSTRACT OF THE DISCLOSURE     The present invention relates generally to a resilient clip for supporting elongated articles such as cylindrical and ribbon-like electrical conductors, and the like.  The invention disclosed includes a base member which may be secured to a support by an adhesive and/or a retaining fastener.  The base has an integrally formed flexible arm extending upwardly therefrom which superimposes the exposed side of the base.  The free end of the arm has a hinged connection and a pressure plate integrally formed therewith, with the hinged connection interposed between the end of the arm and the pressure plate.  The pressure plate position when the clip is relaxed, normally is adjacent to ant substantially parallel to the base.  The hinged connection at the free end of the arm is formed by a reduction in the thickness of the material adjacent to where the arm attaches to the pressure plate.  The end of the arm and the pressure plate are deflectable outwardly away from the base and the pressure plate is pivotable relative to the end of the arm to permit an article or articles to be inserted between the plate and the base.  The pressure plate, when clamping plural or flat ribbon-like articles, will self-adjust to exert an equalized pressure to each article at the point, or points where the article engages the plate.

Abstract: ABSTRACT OF THE DISCLOSURE     An electromagnetic friction device for torque transmission including an input member and an output member.  A mechanism for transmitting torque from the input member to the output member is provided. The torque transmitting mechanism includes an adjustable friction ring member, an inner ring member threadably disposed in the friction ring member and a biasing mechanism.  The biasing mechanism urges the adjustable friction ring member into engagement with the input member.  An electro-magnetic actuating mechanism is mounted adjacent to the output member to move the friction ring member into and out of engagement with the input member.  An adjusting mechanism of the electromagnetic actuating mechanism is adapted to adjust the magnetic armature member with respect to the adjustable friction ring member.  The adjusting mechanism includes a helical biasing member mounted on a connector which connects the armature member to the friction ring member.  The helical biasing member has one radial end portion which is contiguous with the threaded first inner diameter of the friction ring member and an opposite radial end portion which is con-tiguous with a knurled second inner diameter of the friction ring member. The one radial end portion provides controlled rotational drag during adjustment for wear between the inner body member and the friction ring member.  The opposite radial end portion in conjunction with the knurled second inner diameter permits unidirectional rotational movement of the inner body member relative to the friction ring member.

Abstract: ABSTRACT           A process is disclosed for preparing a titanium catalyst com-ponent  useful for homopolymerizing 1-alkenes and for copolymerlzing 1-alkenes with each other and/or with ethylene, consisting essentially in grinding a titanium halide compound/electron-donor complex with a magne-sium aluminum halide obtained by precipitation from an organic solvent.         In the process the ground product is first washed with a solvent  for the aluminum halide/electron-donor complex which forms during the grinding process, and then the washed ground product is exposed to a liquid titanium halide compound.         With this procedure, it is possible to obtain a titanium com-ponent which imparts to the polymerization catalyst an excellent stereospecificity along with a very high activity, and with which it is possible to obtain polymers, e.g. polypropylene, with a very low halogen content and a very low titanium content.
