Abstract: Dense vias may be made with a metallizing composition containing tungsten, alumina, and either nickel or palladium. Further, an infiltration process ensures that vias in ceramic substrates are heremetic. Infiltrating materials, including metals and alloys, are applied to co-fired substrates and the composite is fired. The process may be repeated if necessary. Alternatively, the via holes may be bore-coated prior to infiltrating.

Abstract: There is proposed an installation for measuring quantities of liquid (of the liquid measuring motor type) with two cylinders of which the pistons cooperate by means of cranks. Each piston has a crankpin. To vary the crank radius of a crankpin and thereby vary the stroke of a piston for the fine adjustment of the traversing fluid quantity, the eccentricity of the pin is adjustable with respect to the crankshaft in two parts. To this effect, the pin pivots on a turning portion of an eccentric sleeve, said sleeve being closely connected by a worm screw to the crankshaft. Both pins are arranged on a guiding disc with an angle of 60.degree. with respect to their axes, they are supported by roller bearings and cooperate with the pistons which are connected to two mutually guided parallel cross-slides.
