Patent DE-19757475-A1 (DE)
Inventor: BIRKELUND MICHAEL
IPC: F16K31/40
Filed: 1997-12-23
Abstract: A servo-controlled magnetic valve has a main valve (13) and a servo valve (14). The servo valve opens when, after an empty stroke, a solenoid plunger (7) entrains a slide member (23) that carries the servo closure member (20) and, as a result, pressure is released to the low pressure side (17) from a pressure chamber (25) on the side of the servo piston (24) that is remote from the main valve seat (15). The servo piston (24) is an annular piston that surrounds an insert (19) that carries the main valve closure member (18) and the servo valve seat (20) and which, during the operating stroke, entrains the slide member (23) by means of first stops (26) and the insert (19) by means of second stops (28). In that manner, it is possible to obtain sufficient opening of the main valve (13) and a small overall height of the magnetic valve whilst retaining an initial empty stroke of the solenoid plunger (7).

Title: Reading off of swinging or oscillating indicator from initial response of swinging indicator of electrically compensated weighing unit
Inventor: POULIS JOHANNES AALDERT
IPC: G01G23/36
Filed: 1998-06-13
Abstract: Several discrete measurement values are taken successively over time, the values taken from continuous input indicator. The method is carried out so an approximate value for the weighing result of the swinging indicator of a weighing unit is determined. The initial response of the measurement signal is observed continuously or in several discrete measurements. With the help of the differential equation of the swinging and with a previously determined appliance constant. A balanced wt. position is computed from the initial response of a computer, with this at rest. By the application of electric pulses on the output signal, which is determined from the approximate value, the weighing unit is brought in to the rest position, and the weighing result read off in the rest position.
