Zusammenfassung: | 1,210,086. Pneumatic gauges. SOC. GENERALE DU VIDE. Dec. 14, 1967 [Dec. 15, 1966], No. 56851/67. Heading G1M. The nozzle of a pneumatic gauge has an inlet 4 and two outlets 6, 7 inter-connected at a cavity 5 such that the back pressure caused in cavity 5 by an object placed adjacent the outlet 6 is measured by a gauge connected to outlet 7. By making the inward length H of the slot 6 vary according to the position along L, the external width of the slot, the back pressure is made to be a linear function of the position of the edge of an object placed adjacent to the slot. |
