Patent EP-0047896-A1 (EP)
Inventor: OLSON JERRY ANDREW
IPC: G01F1/36
Filed: 1981-08-28
Abstract: An air flowmeter (10) includes a main air flow passage (26), a relatively small venturi tube (28) receiving a portion of the air flow, a pressure port (74) for sensing stagnation pressure in the main passage, a pressure port (70) for sensing static pressure in the throat of the venturi, and a complimentary pair of sets of stationary swirl vanes (30, 32) disposed adjacent the outlet of the venturi to impart an air swirl in the main passage, thereby creating a reduced pressure at the venturi outlet for amplifying the pressure difference between the stagnation and static pressures. The sets of swirl vanes are rotationally displaceable with respect to one another, allowing some of the air to bypass the effect of the swirl vanes without being diverted to a separate passageway. This arrangement results in a fluid flowmeter having a characteristic pressure drop which is less than that for a conventional device, particularly at high flow rates.

Abstract: Verbaukörbe zum kontinuierlich fortschreitenden Verbau von Kanalgräben bestehen im allgemeinen aus zwei starren, im Abstand gegenüber gehaltenen Schalungswänden, die über Hydraulikzylinder durch das Erdreich hinduchschiebbar sind. Beim Hindurchschieben müssen aufwendige und meistens nicht sehr effektive Stützvorrchtungen vorgesehen werden, um ein Absinken des Verbaukorbs an der Vorseite zu vermeiden. Die Erfindung zeigt eine konstruktive Möglichkeit auf, wie dieses Absinken vermieden werden kann. Erreicht wird dies dadurch, daß die Schalungswände (1, 2) in der Längsebene geteilt und lediglich über Führungen (13, 31) verbunden sind und daß zwischen diesen Schalungswänden (1, 2) doppelt wirkende Hydraulikzylinder (7, 8) angeordnet sind. In einer bevorzugten Ausführung werden die Hydraulikzylinder (27) jeweils an einem Pendelhelbel (21) angelenkt, dessen Pendellager (22) an der oberen Schalungswand (2) befestigt ist und dessen freies Ende in ein an der unteren Schalungswand (1) angeordnetes Schiebelager (24) eingreift.
