Abstract: A conveying apparatus for advancing packages from an inlet station to an outlet station comprises an intermediate track between the inlet and outlet stations, an endless belt to engage the packages during advancement along at least the track; and a tensioning device to tension the endless belt. The tensioning device comprises a spring unit comprising first and second spring assemblies having first and second pre-loaded spring forces respectively, with the second spring force larger than the first spring force. The conveying apparatus is in a rest configuration in the absence of packages along the track and is in a loaded configuration with plural packages arranged along the track. The first spring assembly determines the spring force of the spring unit when the conveying apparatus is in the rest configuration and the second spring assembly determines the spring force of the spring unit when the conveying is in the loaded configuration.

Abstract: A conveyor belt system is provided for enabling rotation of a number of packages, such that every second package is rotated clockwise, and every other package is rotated counter clockwise. A computer program product is also provided.

Abstract: There is provided a process for the production of a N-protected azetidine-2-carboxylic acid, which process comprises the steps of: (a) addition of base to an aqueous solvent comprising an organic acid addition salt of an azetidine-2-carboxylic acid; and (b) addition of protecting agent to the resultant reaction mixture.

Abstract: There is provided a process for the production of a compound of formula I, which process comprises reaction of a compound of formula II, with a compound of formula III, wherein R1, R2, n and R3 have meanings given in the description.

Abstract: There is provided lower alkanesulphonate salts of cyanobenzylamines, which salts may be produced via a selective recrystallisation process. The salts may be produced advantageously following the selective hydrogenation of a dicyanobenzene to a cyanobenzylamine in the presence of a C3-5 alkyl alcohol.
