Device for taking orders of meals or drinks. It is characterized by optical bar code readers (4, 5, 6) which are provided on each table of the restaurant. The data provided are analyzed by a programmed system after they have been sorted out by means of a multiplexer (7) which supplies the data to a computer (1) having a key board (2) and a cash-desk printer (3). An interface (8) sends the data eit...

PURPOSE:To efficiency improve processing in the whole of a system, by allocating a block to a process flexibly corresponding to the state of the system. CONSTITUTION:At the time of generating a stack fault, the existence of a queue element in a queue matrix 12, and a ready matrix 11, is investigated, and when it exists, the process with the lowest priority 41 is detected, and also, the use of an a...

The invention has as its object multi-coat nonskid surfacings which comprises one or more priming coats and one or more nonskid coats. Each coat comprises a base and a hardener which are mixed before use. The bases contain in particular hydroxylated vinyl terpolymer resins and the hardeners contain a polyisocyanate which reacts with these resins to yield cross-linked polymers known as polyvinyl ur...
