Abstract: Sulphamoylathiophenes of the formula ##STR1## in which Y denotes O or S,A denotes a single bond or a straight-chain or branched alkylene group having 1-5 carbon atoms,R.sub.1 denotes methyl or trifluoromethyl andR.sub.2 denotes hydrogen or a group COOH or COOR.sub.3, in whichR.sub.3 represents (C.sub.1 -C.sub.4)-alkyl,and, in the case in which R.sub.2 denotes a group COOH, their pharmaceutically tolerable salts, a process for their preparation, pharmaceutical preparations which contain these compounds and their use in medicaments as leukotriene antagonists for the treatment of asthma and allergies.

Abstract: A system for continuously checking the integrity of the memories of a computer controlled gaming device. The gaming device includes a plurality of EPROMs for storing software and fixed data according to which the gaming device operates. A checksum algorithm stored in one of the EPROMs is periodically implemented throughout the operation of the gaming device to calculate individual checksums for each EPROM. The checksum calculated for an EPROM is compared to a checksum value stored for that EPROM to determine whether changes in the contents of the memory have been made.
