Abstract: High-pressure washing liquid spray intended for use in a washing machine for ophthalmic glass or other substrates, consisting of an entry opening (11) for washing liquid and an exit opening (12) for liquid in a jet, connected by a channel. The channel (1) has a rectangular channel in cross section which introduces a constriction, in particular in the center, giving that channel an X shape, so as to form, on one hand, downstream of the above-mentioned constriction, an expanded exit cavity (13) ending in a slit forming the exit opening (12) and, upstream of the above-mentioned constriction on the other hand, an entry cavity (14) in the base cone where the rectangular base forms the entry opening (11) of the channel (1).

Abstract: Device for the regulation of the concentration of a product in a liquid and, most specifically, of an alcohol used in the composition of a varnish contained in a varnishing vat for optical glasses or other substrates. The vat comprises an overflow tray and a sealed alcohol reservoir. The reservoir is installed higher than the overflow tray so that when level of the varnish in the overflow tray drops sufficiently low, an air bubble is created that rises to the alcohol reservoir, thus creating additional pressure in the alcohol reservoir and forcing a drop of alcohol into the overflow tray until the level of the varnish in the overflow tray recovers its normal level above the junction point between the second pipe and the overflow tray.
