A positive image is formed in real time on one face of an inked ribbon (R) by means of a selective thermal transfer of ink with the use of a thermal dot-line or dot-matrix printing head (H). The positive image is then transferred from the inked ribbon (R) to the article (A) with the use of a heating pad (P).

A damping elastic support, especially for bicycle saddles, comprises an elongated body 2 of elastomer or polyurethane polymer material having elastic properties and with elastic memory provided with tapering end portions 3; 4 which can be compressed along its own longitudinal axis O. Body 2 has a substantially continuous and substantially ovoidal outer surface and a through axial cavity 5 which co...

Waterproofing membrane based on oxidised bitumen for polymer-modified bitumen the top of which is covered with granules (shot) of at least a mineral or polymer material and in addition to having a longitudinal selvage 2 has a transverse selvage 3 so that a perfect weld can be made both longitudinally between membranes alongside each other and at the ends between membranes placed one after the othe...

The bottle consists of a container body with a dispensing opening at one end covered by a drinking cup (14). The cup includes an internal cylindrical projection (17) which engages at least the end portion (5) of a flexible drinking teat (4) attached to the container dispensing opening. The internal projection forms a close fit with the end of the teat such that any liquid spillage from the teat, i...

A class of organometallic polymers of general formula I which demonstrate non-linear third order optical properties is described. The method for preparing the aforesaid compounds is also described.

Solid blends of stabilizers for polymers including an organic polymer and at least one siliconic compound having a sterically hindered amine group in the molecule in quantities of between 40% and 90% by weight of the final solid blend.

Polymers having a very good combination of chemical, mechanical and process properties, and particularly useable either alone or as mixtures, as high-tenacity thermoplastic polymer and as elastomers or elastomeric modifiers, contain, randomly distributed along their chain, repeating cycloketonic structural units having the following general formula (I): wherein: A represents a tetraval...

A process for the preparation of derivatives of 2-(2- aminothiazol-4-yl)glyoxylic acid of formula I through the ozonisation of a corresponding 2-(2- aminothiazol-4-yl)-2-propinoic acid of formula II and possible removal of the N-protective group and saponification of the ester is described.
