Abstract: A method and apparatus are provided for communicating text messages between a first terminal and at least one second terminal that are connected by a communications network. Initially, the terminals communicate according to a first mode in which all the characters of a validated message are transmitted at the validation of said message. Then, the terminals switch into a second communication mode in which each character of a message is transmitted following its introduction on a keypad. The switching from the first mode into the second mode takes place when a terminal, while it is introducing a message, receives at least one signal indicating the introduction of a character on the keyboard of the other terminal.

Abstract: Modified crude toluene diisocyanate characterized by the fact that it is obtained by reaction first of a crude toluene diisocyanate with a polyol in such a quantity that the lowering of the isocyanate concentration of the crude toluene diisocyanate at the most amounts to about 2.0--NCO groups per kilogram of crude toluene diisocyanate and by the fact that in a second step the above reaction product is aged under heat application for such a temperature and period of time that the lowering of the isocyanate concentration of this reaction product at the most amounts to 0.4--NCO groups per kilogram of product. This modified crude toluene diisocyanate can be used for making high resiliency polyurethane foam with improved properties.
