  • Patent number: 10221193
    Abstract: Disclosed is a method for the photoinitiated transformation of a transformable reactive substrate. The method includes an initial step in which a protected ketone photoinitiator species which is present in the substrate is deprotected to form the corresponding ketone photoinitiator species for use in a subsequent photoinitiated reaction in the method. The ketone group of the photoinitiator is protected by an unsubstituted 1, 3 dioxolane group. Also disclosed are a composition which may be used in the method, the use of the protected ketone photoinitiator in a photoinitiated reaction, as well as the protected ketone photoinitiators themselves.

  • Publication number: 20170259317
    Abstract: The present application describes a system to compensate deformations in press bending machines, in particular press bending machines used for plate conformation or bending, which comprises a group of uprights (1) for supporting the upper apron (7) of the press bending machine, wherein each upright (1) comprises two beams (2,3) placed on the upper and lower ends of a pillar (4) being coupled thereof by means of fastening means (5) and a compensation actuator (6) placed between the beams (2,3) and coupled to the beam (3) at one end thereof. The presented technology allows to increase the distance between the aprons of the press bending machine and the upright scye (1) so that said press bending machine allow the plate deformation in various shapes and dimensions.

  • Patent number: 7750246
    Abstract: An electric cable includes an electrical conductor surrounded by a first layer of mica tape made up of mica particles deposited by means of a polymer binder on a backing, a second layer of a polyimide tape, and a third layer of a polytetrafluoroethylene tape, where the first layer is subjected to heat treatment at a temperature of at least 400° C. and the ratio R of the weight per unit length of PTFE over the sum of the weights per unit length of the polymer binder and of the polyimide is such that R is greater than or equal to 2 when the section of the electrical conductor is no greater than 0.2 mm2, R is greater than or equal to 4 when the section of the electrical conductor is strictly greater than 0.2 mm2 and strictly less than 0.6 mm2, R is greater than or equal to 6 when the section of the electrical conductor is equal to 0.6 mm2, and R is greater than or equal to 12 when the section of the electrical conductor is strictly greater than 0.6 mm2.
