Abstract: A transport system and method has a support frame which carries at least a first reciprocating conveyor and a second reciprocating reference mass. The reciprocating conveyor and reference mass are connected by springs. The system has at least one first force generating apparatus and at least one activation spring connected to the force generating apparatus. The activation spring is connected to at least one reciprocating conveyor or the reciprocating reference mass. The system and method for vibration transport of goods determines the mass of goods delivered by the transport system. The support frame is carried by at least one load cell. The load cell is connected to a computer system. The computer system performs a calculation of the mass of transported goods. The computer system delivers a continuous measurement of the mass of the goods which are transported.

Abstract: Valve (1) with a through-going axial bore (4), a first spindle (5) axially displaceable in the bore (4), an elastic/flexible seal (10) placed at the one end surface (6) of the first spindle (5), at least two hollow connection branches (7, 8), each of which connects the valve to an outer coupling, said first spindle (5) in a first position forming a first annular sealing surface (9) between the outer surface of the seal (10) and the inner bottom (11) of the valve body which contains the outlet opening (29), and where the first spindle (5) lies coaxially inside a second axially displaceable and hollow spindle (12) lying in the bore (4), the end surface of which or parts thereof (13) form a second annular sealing surface (14) between the outer surface of the seal (10) and the inner bottom (11) of the valve body at a second position radially from the first annular sealing surface (9).
