Abstract: There is described a photomechanical method for forming pressure sensitive transfer reproductions of color images, either single color or multicolor, upon a substrate involving the forming of a base coat protective layer on a substrate, applying one color ink layer on the base layer and a white ink overlayer on the one color ink layer. The surface of the white ink overlayer is powdered and a layer of photoresist composition is applied. The photoresist covered layered substrate is exposed to a light source through an image carrying photographic negative film to harden the photoresist at the imaged areas thereby forming a mask. Nonhardened photoresist composition areas along with their underlaying layers are removed using stepwise solvent development steps. The steps are repeated where different ink colors are to be applied to form a multicolored image. The final single color image or the final multicolor image, as the case may be, being thoroughly dried, finally coated with a pressure sensitive adhesive to form the image transfer sheet. Drying between each step of formation is essential.

Abstract: For charging a battery (6) a self-oscillating power supply circuit is used in which energy is stored in a transformed (Tr) during the  so-called forward intervals, which energy is applied in the form of a charge current to the battery (6) during the so-called flyback intervals. To prevent overcharge of the battery (6), the circuit is provided with an acculmulator voltage protection circuit (10) receiving its power supply from the battery (6), to which circuit a fraction of the battery voltage is applied by means of a voltage divider (R3, R4) which is arranged across the battery (6) by means of a switch (S1) during the flyback intervals. To prevent the voltage drop accross the internal resistance of the battery from influencing the measurement of the battery voltage, the battery voltage is measured after the end of a flyback interval and before the commencement of the next forward interval. To this end the inputs (11, 12) of the accumulator voltage protection circuit (10) are short-circuited with the aid of two diodes (D1, D2) during the flyback intervals.
