Abstract: ABSTRACT OF THE DISCLOSURE           A procedure and apparatus for refining platinum group metal con-centrates and the separation therefrom of silver and of the majority of base metals with which they naturally occur is provided herein.  In more detail the process comprises the steps of:  (a) contacting a solid particulate mix-ture of base, e.g. one or more of Sb, Sn, Pb, Zn, Ca, Ni, Fe, As, Se and Te. silver and precious metal components e.g. gold, ruthenium, rhodium, palla-dium, osmium, iridium, or platinum, any of which components may be in metal-lic or chemically combined form, with a halogen containing gas (e.g., hydro-gen chloride, hydrogen bromide, chlorine or bromine) at a temperature which is below the melting point of the mixture but which is sufficiently high for the base metal and silver components to form their halides and for the halides substantially to volatilize from the solid mixture, and (b) removing the volatilized halides from the solid precious metal-containing component which remains.  The apparatus provided herein for carrying out the process com-prises: (a) a gas-tight means for feeding particulate solid into a tubular vessel constructed of a refractory material; (b) a vertical shaft reaction chamber connected to the tubular vessel and having an inlet for the intro-duction of halogen-containing gas and an outlet for exhaust gases including volatilized halides; (c) heating means, disposed around the shaft reaction chamber, and (d) a discharge system, whereby precious metal-containing residue may be ejected from the reaction vessel.

Abstract: PROCESS FOR MAKING LOW-SULFUR AND LOW-ASH FUELS                           . .                      ABSTRACT OF THE DISCLOSURE          Low-sulfur and low-ash gaseous, liquid and solid fuels are made from coal by a process which first subjects the coal to solvent extraction and hydrotreatment under hydrodesul-furizing conditions in a coal liquefaction zone to reduce the organic sulfur content of the coal.  The effluent is divided into a low-solids product which contains most of the extract and a high-solids product which contains most of the remaining inorganic sulfur and other mineral matter.  The low-solids product stream which contains extract and solvent is subjected to a forming step to yield low-ash and low-sulfur pellets.  The high-solids product stream is subjected to gasification to yield hydrogen for use in the liquefaction step.  The process is particularly adapted to supply the energy needs of a steel plant, including the required coke.

Abstract: NARROW MULTI-POLE CIRCUIT BREAKER  HAVING BODILY MOVABLE INSTANTANEOUS TRIP STRUCTURE      Abstract of the Disclosure.           A plurality of single pole circuit breakers stacked side-by-side are interconnected by a tie rod connecting the magnetic armatures of their respective instantaneous trip means.  When one pole is caused to trip because of a fault condition a driving cam formation on the releasable cradle of the faulted pole engages the armature moving it in the tripping direction substantially beyond the point required for releasing the cradle latch in the faulted phase.  Substantial  movement beyond cradle release is permitted even though the magnetic air gap at the armature is small in that after this gap is closed the magnet is moved bodily in the tripping direction. This added movement assures that the tie rod shall transmit sufficient motion to all non-faulted poles to cause tripping thereof.

Abstract: SPRING TRIP CULTIVATOR SHANK ASSEMBLY                   ABSTRACT OF THE DISCLOSURE         A self-restoring spring trip cultivator shank assembly adapted to be supported from a mounting bracket secured to the transverse tool bar of a ground-working agricultural implement.          The lower end of the cultivator shank carries a ground-working tool and the forward end extends between a pair of laterally spaced side plates which are supported by the mounting bracket contiguous the under surface of the tool bar, the forward end of the cultivator shank being adapted to pivot about the peri-pheral surface of a pivot pin which extends between and through the laterally spaced side plates.  An abutment member in the form of leaf spring which extends in overlying contacting engagement to the upper surface of the cultivator shank is suitably held against the forward end portion of the cultivator shank to maintain the cultivator shank in pivotal bearing rela-tion against the peripheral surface of the pivot pin.  A loading spring subassembly supported from the mounting bracket is adapted to engage the rearward end of the leaf spring whereby to transmit the spring loading force to the leaf spring and thus to the cultivator shank which is in under-lying contacting relation to the leaf spring.  When the tool carried by the lower end of the cultivator shank engages an obstacle such as a rock, the cultivator shank will pivot up-wardly and forwardly about the pivot pin carried by the side plates, this movement of the cultivator shank causing com-pression of the loading or compression spring.  When the earth-working tool has passed the obstacle, the loading spring will return the cultivator shank to a position in which the tool carried by the shank is again in proper earth-working position.

Abstract: ABSTRACT OF THE DISCLOSURE     A drink shaker for mixing solids, and particularly those that tend to lump, and liquids, to mix beverages.  The shaker comprises first and second containers of  tumbler configuration, and a basket member formed to have its side wall and floor of a foraminous character.  The basket member is to receive the solids to be mixed into the liquids of the drink and the basket member is formed to rest within the first container on a ledge structure provided for that purpose.  The basket member is also formed for friction fit reception and retention within the second container.  The second container is formed for a plug fit liquid sealing securement application within the first container.  The basket member is shaped to provide for movement of the liquids on shaking into the second container for application to the solids in the basket member from both sides of same.  With the liquids to be mixed placed in the first container and the solids to be mixed placed in the basket member that is then rested in the first container, the second container is seated on the first container in liquid sealing relation thereto as well as in friction fit retention relation to the basket member.  The basket is so constructed as to facilitate fra-gmentation and dispersion of the solids into the liquids, during the shaking operation.  When the shaking is completed, separation of the containers effects removal of the basket member from the first container as a unit with the second container which may be rested in an upright position that automatically disposes the basket for drainage flow therefrom into the second container.
