Title: Process for the production of furnace black
IPC: C09C1/50
Filed: 1975-02-27
Abstract: 1500738 Furnace black DEUTSCHE GOLDUND SILBER-SCHEIDEANSTALT 27 Feb 1975 [6 March 1974] 8221/75 Heading CIA Atomized liquid feedstock and fuel gas are introduced into a furnace-black reactor provided with a constriction, by means of a burner/injector combination in which the liquid feedstock is introduced through an inner tube with an outlet nozzle, a gaseous atomizing medium is introduced through a jacket tube with a conical taper in front of the inner tube outlet nozzle; and the fuel gas is supplied by an outer jacket with 4-12 gas outlet openings distributed over 360 degrees such that the fuel gas pressure in the burner exceeds 15 atmospheres, and the fuel gas outlet velocity is at least 320 ms<SP>-1</SP>. The number of gas openings and their size is preferably selected to give a fuel pressure of 2-6 atmospheres. The free diameter of the injector outlet nozzle is generally from 40-75% preferably 50-65%, of the free diameter of the jacket tube through which the atomizing medium is introduced. It is advantageous for the feed pipe of the feedstock injector to terminate in the conical part of the jacket tube, and for the interval between the injector opening and the end of the outlet nozzle to be 60-120% of the diameter before the conical taper of the jacket tube through which the atomizing medium is introduced. The constriction gives favourable results when the cross-sectional area of the reactor is reduced to a third or less, preferably to “-1/10, of its previous cross-sectional area. The average particle size, iodine adsorption, ash residue, and pH value of a carbon black, produced according to the invention, are given in the example.
Patent GB-961893-A (GB)
Title: Improvements in solutions of quaternary ammonium borohydrides in liquid hydrocarbons
IPC: C07F5/00
Filed: 1962-03-02
Abstract: The invention comprises a reagent for effecting reduction of organic compounds comprising a quaternary ammonium borohydride having the formula Rx(CH3)yNBH4 where R is a saturated or unsaturated straight chain aliphatic hydrocarbon radical containing from 7 to 21 carbon atoms and x and y are integers from 1 to 3 and x+y equals 4, in solution in an inert liquid hydrocarbon, such as benzene, hexane, ligroin or mineral oil.  The quaternary ammonium borohydride may be made by adding a solution of the quaternary ammonium chloride in isopropanol to a methanolic solution of sodium borohydride and sodium hydroxide, filtering off sodium chloride and removing solvents by vacuum distillation. The above reagent may be used to reduce an organic compound having a reducible functional group e.g. an aldehyde, ketone, acid halide or organic peroxide at a temperature sufficient to cause reduction but low enough to avoid thermal decomposition of the borohydride. Examples describe the reduction of p-hydroxybenzaldehyde to p-hydroxybenzyl alcohol; 2 ethyl hexaldehyde to 2-ethylhexanol; p-nitrobenzoyl chloride to p-nitrobenzyl alcohol; benzoyl peroxide to benzoyl anhydride; ethyl p-nitrobenzoate to p-nitrobenzyl alcohol; and benzoyl chloride to benzyl alcohol.

Title: Method of and apparatus for forming balls
IPC: B21H1/14
Filed: 1925-03-30
Abstract: 253,261. Canda, A. March 30, 1925. Rolling balls; axial rolling.-In a mill for rolling metal balls, a rod or bar of metal is fed between a pair of rolls 10, 12 having a number of spiral grooves of varying configuration which progressively shape the ball elements, which are then separated by the rolls and finally finished by a spiral rolling action. The rod 14 passes through a guide 27 and is guided during its passage through the rolls by members 18, 19. The rolls comprise grooved shells fitted over cores 25 and the grooves are shaped so that sharp ribs 20 cut gradually into the bar while the flat portions 21 and the inclined sides of the groove consolidate the metal of the blank. After approximately onethird of the rolls have been traversed the blanks are severed and the groove g remaining in the partly formed blank is eliminated by the spiral rolling movement which occurs during the passage through the next succeeding grooves. The blanks then enter the< >finishing grooves which are of round section, the width of the pass being gradually narrowed to the size of the finished ball. During the last stages of the operation each ball rotates on an axis which has an orbital movement as shown at c, Fig. 7. The finished balls pass on to a shoot 16. In an example given, the rolls may be 26 inches in diameter and may have 22 grooves with a lead angle of 30‹. In a modification, a number of rolls may be arranged for simultaneous operation on a number of stock bars as shown in Fig. 8.

Class 110(iii) [Also in Group XXVII] Relates to a power plant incorporating a twostroke internal-combustion engine G of the compression ignition type wherein each cylinder A has a ring of exhaust ports B superimposed above a ring of combined scavenging and charging ports C adapted to deflect the scavenging air upwards in the centre of the cylinder and then downwardly along the cylinder walls. Such a plant comprises a compressor H which is driven by a rotary part thereof and supplies scavenging air to the internalcombustion engine and a useful power turbine J which produces power in excess of that required to drive the compressor and is driven by the exhaust gases of the internal-combustion engine. The exhaust gases of the gas turbine are discharged through a jet propulsion nozzle L. The internalcombustion engine and the gas turbine jointly drive the compressor and a propeller T, through suitable transmission gearing. In a modification the propeller and the compressor are respectively driven by the turbine and the internal-combustion engine through suitable gearing. In a further modification, the turbine drives the propeller through transmission gearing and directly drives either a lowpressure compressor or a high-pressure compressor whilst the internal-combustion engine drives a second propeller and the high- or the low-pressure compressor, as the case may be, through transmission gearing. Specification 596,819 is referred to.
