Abstract: Abstract of the Disclosure An improved process for the preparation of alumina, including forming an alumina hydrogel from aluminum hydroxide, and processing the alumina hydrogel into alumina.  The improvement involves the alumina hydrogel forming step which is conducted in the presence of sulfate ion and which comprises providing, in a reaction zone, an aqueous slurry containing seed aluminum hydroxide and having a pH of 6 - 11, and feeding to the reaction zone an aluminum compound and a pH controlling agent for mixing with the aqueous slurry while maintaining the aqueous slurry at a temperature of at least about 50°C at feed rates so that the pH of the aqueous slurry is maintained within the range of 6 - 11 and that 0.2 - 5 mols/hour of aluminum components, in terms of elemental aluminum, are fed to the reaction zone per mole of the seed aluminum hydroxide originally contained in the aqueous slurry, whereby the seed aluminum hydroxide is caused to grow to the aluminum hydrogel.

Abstract: ABSTRACT           A method for slip-limiting control on a rail vehicle and slip-limiting control device.  For controlling or limiting slip, it is necessary to determine the actual speed of the rail vehicle.  This presents problems in traction vehicles such as, for example, locomotives which only have driving wheels and no running wheels, especially if all driving wheels slip simultaneously.  For the accurate determi-nation of the vehicle speed, the traction motor current for the associated motor is reduced for a short period, of about 3 seconds, at the driving wheel which is rearmost in the direction of motion, by means of a slip-reduction signal which is supplied to a slip-limiting controller which also reduces the speed of this driving wheel so that this wheel no longer slips and its peripheral wheel speed is equal to the vehicle speed.  During a presettable long-term period of about 25 seconds, all slip-limiting controllers of the rail vehicle are preset with a speed reference signal (Vref) having a slight rise in speed so that the peripheral wheel speed of the driving wheel is somewhat greater than the vehicle speed but not great enough for the wheels to spin.  A jolt detector is provided for initializing this measure.

Abstract: HYDROCRACKING PROCESS USING ZEOLITE BETA       ABSTRACT OF THE DISCLOSURE          A hydrocracking process for feedstocks containing high boiling, waxy components uses a number of sequential beds of hydrocracking catalyst based on zeolite beta.  The proportion of zeolite beta in the catalyst increases in sequence so that the final bed has the nighest zeolite concentration.  The dewaxing activity of the zeolite beta-containing catalysts is enhanced by the use of sequential beds in this manner.  The pour point of the high boiling fraction is reduced, as well as that of the distillate product, permitting part of the high boiling fraction to be included in the distillate product, thereby increasing the useful distillate yield.
