Abstract: Abstract of the Disclosure Fine particulate solid fuel is utilized in the calcining or uniflow shaft of a uniflow regenerative shaft furnace having outlet openings of fuel lances of the furnace arranged with a uniform distribution over the cross-section of the furnace shaft in a horizontal plane between the preheating zone and the calcining zone of the furnace.  The fuel feed is maintained constant with time by a dosing system through which fuel is supplied through feed lines to the fuel lances.  Due to the uniform distribution of solid fuel which is accomplished, a calcined material is obtained which has a quality comparable to that which may be achieved through calcining with gaseous or liquid hydrocarbons.

Abstract: PURIFICATION OF HYDROCARBONS BY                     TREATMENT WITH POLYAMINES                              ABSTRACT        Isoprene and butadiene are purified by treating a petroleum refinery C4 stream or petroleum refinery C5 stream which contain butadiene or isoprene or relatively pure butadiene or isoprene and carbon disulfide by treatment of these streams with from about 1 to about 7 equivalents of a polyamine.  The polaymine reacts with the CS2 impurity to form the dithiocarbamate salt.  The hydrocarbon is then separated from the dithiocarbamate salt and any excess unreacted polyamine by water washing this stream or by flash distilling of the hydrocarbon.

Abstract: SPECIFICATION     Title of the Invention CONTINUOUS THERMAL CRACKING METHOD OF HEAVY PETROLEUM OIL             Abstract of the Disclosure The specification describes a method for producing thermally-cracked products of high quality such as gas, cracked light oil and pitch by continuously subjecting heavy petroleum oil to thermal cracking in a single-column reactor. More specifically, heavy petroleum oil, which has been heated in a heating furnace to a temperature of a predetermined range, is continuously charged into the lowermost reaction zone of a column-like reactor which is vertically divided into a plurality of reaction zones by means of at least one partition wall defining an opening therethrough to make said reaction zones to communicate with one another.  The heavy petroleum oil is subjected in the reactor to thermal cracking while maintaining its temperature, pressure and residence time in the reactor within their respective predetermined ranges and causing oil, which has been treated in each of said reaction zones, to be successively transferred to its upper reaction zone together with bubbles under stirring conditions.  Then, the thus-cracked product is continuously discharged from the uppermost reaction zone of the reactor.

Abstract: Abstract of Disclosure A automatic voltage regulating transformer is pro-vided which incorporates a potential transformer electrically disposed across  its  series windings,  and a set of sensing windings disposed  across  its  shunt  windings  to provide  a voltage sensing network which is responsive to the flow of current both into and out of the transformer.  The output of the potential transformer  is connected  in series with  the sensing windings to provide a control voltage which is repre-sentative of the voltage across the shunt windings and series windings taken together.   In the case of a normal voltage regulating transformer, this control voltage is proportional to the voltage across the output terminals.  In the case of an inverted  regulating transformer,  the output voltage of the voltage sensing network is proportional to the voltage across the input terminals.   In each case the same control voltage can be used to automatically operate the transformer whether or not current is flowing into or out of the input terminals of the transformer.  In one embodiment the tertiary winding that is used to provide voltage to operate the tap changing mechanism of the transformer is also used to provide a voltage proportional to the voltage across the shunt windings.

Abstract: APPARATUS FOR NAILING PICKETS ON STRINGERS            ABSTRACT OF DISCLOSURE          Apparatus for securing pickets to elongated stringers employs a worktable having stringer accomodating channels into which the elongated stringers are placed.  A picket hopper acco-modates a stacked array of pickets transverse to said channels and stringers.  A reciprocating carriage assembly is positioned on the worktable and reciprocates a given distance in a forward and back-ward movement.  As the carriage moves forward the lower most picket in said hopper is pushed to a fastening location. Located at this location and above the pushed picket are fastening means, which are air actuated nailing guns.  The guns are mounted on a shaft which is synchronized with the carriage assembly to cause the guns to move about an arcuate path which causes the guns to contact the picket at the fastening location to secure the same to the strin-gers.  Also including are side locking means which are located in the stringer channels and which force the stringers against the vertical channel walls during carriage motion to provide a consis-tent product.  The operation is automatic and each successive pic-ket is secured to the stringers by the carriage pushing the next pic-ket against the last picket nailed.  In this manner the carriage assembly pushes the completed product away from the fastening loc-ation at increments equal to the picket width and this action occurs for a picket of any width.  The action of the apparatus further assures that each picket is straightened or aligned with the last secured picket due to the forces exerted on the pickets by the carriage assembly.  Other features as synchronizing means for the entire operation are described.

Abstract: ABSTRACT:          X-ray analysis apparatus with an adjustable stray ra-diation slit.           In an X-ray analysis apparatus, there is pro-vided between a test specimen (5) or an analysing crys-tal and a detector (9) a stray radiation slit (15) that can be adjusted in dependence on the goniometer angle.          By an optimum adjustment of this slit in correspondence with the variation in the goniometer angle it can be achieved that the detector will always see the same por-tion of the surface of the test sample or analysing crys-tal. Especially, the adjustment of the slit is coupled to the adjustment of an automatic divergence slit (11) so that the portion of the surface which is irradiated, remains unaltered. Especially for small goniometer angles, that is to say for the analysis of a substance in which there is a large distance between crystal planes, a considerably improved signal-to-noise ratio in the measurement signal is thus obtained.
