Abstract: A composition of matter comprising both (1) zeolite Beta and a (2) Y zeolite having either a unit cell size below about 24.45 angstroms or a water vapor sorption capacity at 25.degree. C. at p/p.sub.o of 0.10 of less than 10.00 weight percent. Typical of the Y zeolites used in the composition of the invention is a UHP-Y zeolite such as LZ-10 zeolite. The composition is especially suited for use in combination with one or more hydrogenation components as a catalyst for hydrocracking various types of feedstocks to produce either gasoline or middle distillate products.

Abstract: A data processing arrangement is operative to combine data representing different kinds of information from disparate sources. The data is stored under assigned addresses having a mutually compatible co-ordinate format, and is processed using those addresses. Relevant portions of data from a very large amount of information can be readily extracted in this way, and combined with other data which is related by virtue of a common address. The arrangement is applicable to flight management of an aircraft.
