Title: Method for application of colours and tonalities to various surfaces.
Inventor: CARRASCO MARTINEZ VICENTE
IPC: B41M1/14
Filed: 1998-02-04
Abstract: The invention relates to a method for applying colours by subdividing them according to their percentages allocated to each of the printing points which are for example divided centesimally in accordance with a rule which defines the distribution of appropriately superimposed basic colours, thereby creating binaries and blacks according to the subtraction of the percentage of the basic colour most used percentually from the sum of basic colours less used percentually. Thus, the totality of visible colours are optically generated. The background of the surface to be printed is previously analysed and the percentual quantity in each point of the based colours is deducted in the proportion contained in said background. The application of pigments is carried out by addition of a transparent substrate or medium or white until the proportion of each colour is completed. Application to graphic arts and to the computer reproduction of colours.

Patent NL-7812150-A (NL)
IPC: H05B6/68
Filed: 1978-12-14
Abstract: A domestic appliance comprises a programming device for receiving on-time information and for updating, by way of repetitious signals, the ontime yet to be completed. Furthermore, these repetitious signals continuously activate an activation signal which, however, is independently terminated if the repetitious signals do not appear. When the activation signal is present, first and second switching components are activated, so that a discharge tube can emit ultraviolet radiation. Furthermore, there is provided a detection element which detects whether the first and second switching components are indeed deactivated outside the on-time. If one of the two switching components remains active also outside the on-time, the detection element supplies a signal to prevent the starting of a next on-time.
