Abstract: The invention relates to a method for recovering of oil from plant seeds characterized in that a) an aqueous solution containing one or more cellulolytic and/or lipolytic and/or pectinolytic and/or proteolytic enzyme(s) and/or phytase is sprayed onto the seed, b) the thus obtained seed is directly supplied to a one-stage or multistage pressing in a way known per se, optionally coupled to an extraction, and c) the oil is recovered in a way known per se and optionally further processed, and the use of the method, particularly in the production of edible oil or biodiesel.

Abstract: The invention relates to an integrated gas regulating and safety valve for burners of a modulatable gas heating device. According to the invention, the gas regulating and safety valve comprises a housing (1) with two controllable closing elements, the axes of which are spaced apart from each other and extend one behind the other in series in the direction of gas flow between an inlet channel (2) and an outlet channel (4) of the housing. In the de-energized state, the two closing elements abruptly close the gas regulating and safety valve independently of each other, in each case by means of an associated spring element (7, 12). The first closing element, additionally serving for the modulation of the gas stream, has a drive spindle (15.1), which is formed as a spindle of a stepping motor (15), is surrounded by an excitation winding (16) and has placed on its end a restrictor component (8) and, at a distance from that, the first spring element (7).

Abstract: Disclosed is a combined ventilator/gas valve unit (1) at least comprising a gas valve (2) that is disposed in a housing (2.1), a nozzle (3) located therebehind, and an adjoining ventilator (4) which is provided with a multipart ventilator housing (4.1). According to the invention, the suction side (4.2) of the ventilator housing (4.1) is designed as a nozzle (3) to which the gas valve (2) is fastened.
