Title: Improvements in the recovery of sulphur from hot sulphur-containing gases
IPC: C10K1/04
Filed: 1954-09-15
Abstract: Purified and mobile liquid sulphur is obtained from hot gases, such as those derived from the roasting of sulphide ores, by cooling the gas by indirect heat exchange, to a temperature of 0-10 DEG C. above the dew point of the sulphur vapour, bringing the cooled gases into contact with a surface cooled below the dew point of the sulphur vapour and removing particles of liquid and solid impurities so formed; finally the bulk of the sulphur is condensed by indirect heat exchange in one or more further cooling stages.  The indirect heat exchange may be with cold roasting gases or with water to produce steam.  The removal of impurties by cooling to not more than 10 DEG C. below the dew point allows the condensation of sulphur with the impurities and renders the impurities mobile.

Title: Device for the prevention of shaft fractures due to torsional oscillation
IPC: F16F15/16
Filed: 1927-10-21
Abstract: 301,171. Sandner, E. Oct. 21, 1927. Shaft couplings.-In means for damping torsional vibration in shafts carrying heavy bodies, the shaft is divided at or near the modes of oscillation and interconnected by hydraulic pump-like couplings of the reciprocating, gear-wheel, radially-slidable vane, or other type, the exhaust valves being so loaded as to create a rigid connection between the shaft parts except at critical speeds, when the vibration produces excessive torque. Fig. 1 shows such a coupling, in which the crank-pin h on one shaft is connected by rods g to pistons f in cylinders e secured in a carrier c secured to the other shaft. The springs controlling the exhaust valves k which connect the cylinder heads with interconecting channels l, are so strong as only to permit valve movement and thus relative movement between the shafts at critical speeds. The inlet valves i act as ordnary automatic valves. The water, oil &c. employed is maintained normally at approximately atmospheric pressure, provision being made for replenishment of leakages. As shown in Fig. 3, the inlet valves i on one side of the apparatus may be retained in their open positions by lugs m on the rods g, or may be placed in the cylinder heads and actuated by cam gear from the shaft. In this construction, drive can take place from the shaft to the cylinders only in the direction of the arrow, no resistance being opposed to movement in the opposite direction.

Abstract: 1,093,820. Detecting largest pulses. INTERNATIONAL BUSINESS MACHINES CORPORATION. July 2, 1965, No. 28104/65. Heading H3T. To detect which pulse of a series has the greatest amplitude the pulses are applied through an emitter follower 111 to charge a capacitor 116 in the emitter circuit of second transistor 115. The voltage across this capacitor is passed on through succeeding transistors 121, 123, 126, 127, 129 to charge a further capacitor 130. The voltage across the collector load 132 is a differentiated version of the input pulse and is converted into a pulse output at 138 by the common-base transistor 136. A second pulse greater than the first will charge the capacitors up to a higher level, but a second smaller pulse will have no effect on the already charged capacitors. The last pulse obtained at 138 thus represents the largest pulse of the input series. Reset pulses at 120 and 135 discharge the capacitors in readiness for a new series. Capacitor 116 charges rapidly and may discharge partly before the next pulse arrives but capacitor 130 can hold its charge longer and a false indication is not given.
