Abstract: The invention relates to a treatment process for obtaining a non-permanent reshaping of human keratinous fibres, especially hair (setting), which consists in (i) bringing a gas containing water vapour and whose temperature is at least 75 DEG C into contact, for a period not exceeding 2 minutes, with human keratinous fibres maintained under mechanical tension and to which a composition containing at least one silicone has been applied, (ii) cooling the fibres thus treated, and lastly (iii) eliminating the mechanical tension which was applied to the fibres. Hair is thereby obtained which displays long-lasting attractive curls and exceptional cosmetic properties of softness and smoothness.

Granted: 2016-12-30
Abstract: A computer system is disclosed for managing consignment flows in a delivery network comprising network stations for delivery of one or more pieces of a consignment. Upon receipt of a consignment order, the computer systems calculates a scheduled path for delivery of the consignment through the delivery network. The scheduled path is defined from successive predefined path segments between network stations. Each piece is assigned to delivery pipelines between successive network stations on the scheduled route. The delivery pipelines meet a delivery time for delivery of each piece. The computer system receives registration events from registration devices at network stations of the delivery network from the pieces and analyses progress of delivery for each of the pieces through the delivery network by verifying whether the delivery time can be met for each of the pieces when receiving registration events.
