Abstract: ABSTRACT OF THE DISCLOSURE         In the electroslag remelting of steel using at least one self-consumming electrode with an alternating current in a liquid slag which is a conductor of electric current and a water cooled mould causing the resulting liquefied metal to solidify using the principle of a growing ingot, unwanted hydrogen and oxygen are removed by employing at least two non-melting auxiliary electrodes of different polarity connected to a source of direct current, and causing superimposed electric currents to flow between the auxiliary electrodes and the con-summable electrode, between the auxiliary electrodes and the ingot sump, and between the auxiliary electrodes themselves, the superimposed electric currents flowing in the slag in addition to the alternating current between the consummable electrode and ingot sump, whereby electrolysis occurs in the molten phase to cause the hydrogen and oxygen ions to migrate towards the auxiliary electrodes where they react with the air, slag and/or the material forming the auxiliary electrodes.

Abstract: ABSTRACT OF THE DISCLOSURE                In a magnetically actuated switch such as is dis-closed in U.S. Patent No. 3,586,809, the armature stop against which the armature engages in its switch-open position has a pair of vibratile members attached to its tip, in vibration transmitting relation to it and extending lengthwise from it. The two vibratile members are tuned to different frequencies, both lower than that of the armature stop. They so control vibration of the armature stop as to quickly stop the armature at its switch open position.  Similar vibratile members on a relatively stationary contact member eliminate contact rebound upon switch closure.

Abstract: ABSTRACT OF THE DISCLOSURE            A method and apparatus for drying disintegrated fiber mass or paper pulp comprising substantially free single fibers and wads or lumps of fibers.  The disintegrated fiber mass is exposed to hot drying air or gas at a temperature of at least 180°C. Free fibers are separated from the fiber mass during or after the drying process in order to avoid or compensate for excessive heating and drying of these free fibers. This facilitates a later grinding process in which the dried fiber mass is ground after addition of water.

Abstract: Inventor:  Raymond C. Price Title:     APPARATUS TO DEMONSTRATE AIR FLOW THROUGH PERMEABLE  SHEET MATERIAL                 ABSTRACT OF THE DISCLOSURE        An apparatus to demonstrate air flow through sheet material such as carpeting and padding to provide a qualitative, visual test of the permeability of the material.  A transparent, closed container is connected with a vacuum pump to pull air thereinto from an opening at the bottom of the container which is traversed and closed by a sample of the sheet material to be tested.  Thus, air flows into the container by passing through the sheet material. Lightweight objects within the container are agitated by air move-ment and the manner and intensity with which they are bounced and tossed within the container provides for a spectacular, qualita-tive demonstration of the permeability of the material.  Also, a simple comparsion of one material with another is possible with the apparatus.

Abstract: Abstract of the Disclosure In a concrete pipe moulding machine comprising a rotationally vibrated core and an outer mould, deficiencies may occur especially in the upper ends of the moulded pipes due to rather vigorous relative movements between the core and the outer mould. Means are provided to moderately reduce these re-lative movements by neutralizing the tendency of the outer mould to perform a rocking motion caused by the transmission of the rotating vibration forces via the moulding material onto the outer mould.

Abstract: ABSTRACT OF THE DISCLOSURE         A plasma-arc process is disclosed for the production of powders of various chemical products, according to endothermical reactions such as TiC and the like. The process consists essential ly in carrying out, in a furnace with an anodic function without dissipative cooling, a series of steps comprising:         (a) forming a chemically reactive fluidodynamic mass hav ing a high thermal content and a high concentration of the desired reactive species, by injecting into the electronic column of a plasma-arc of a noble gas at least one reactant selected from the class consi-sting of metal and metalloid halides, the injection taking place, with mixing through a choker-injector-mixer nozzle which is electrically insulated;          (b) causing the electronic condensation of said mass in side a main nozzle anode without dissipative cooling and (c) injecting into said electronically condensed mass the residual part of said reactants necessary to the desired main chemical reaction for producing the che mical powder. The total volume of the reactants is equal to or greater than 20% of the total aeriform volume formed by the total volume of the reactants plus the volume of noble gas that pilots and stabi-lizes the plasma-arc itself.     The electronic condensation takes place inside a nozzle-shaped main anode without dissipative (forc ed) cooling, which nozzle anode is made of tungsten or graphite, and preferably the latter. Powders hav ing the function of nucleation such as dispersion agents, may also be introduced into the reaction zone. If desired, a subsequent reaction may be brought about by the chemical and/or physical inter reaction of one or more reactants introduced into a zone of the furnace located below the zone in which the main reaction takes place. The process also contemplates the use of hydrogen only as a reactant of a desired chemical reaction, said hydro gen being injected into the fluidodynamic mass only after this latter has condensed itself electronical ly inside the nozzle-shaped main anode. Examples are given wherein TiC powder is produced from TiCl4 and CH4, employing only argon as the gas for the plasma-arc.
