<p>1,254,292. Push-pull cable controls. DOWTY TECHNICAL DEVELOPMENTS Ltd, 18 March, 1969 [27 March, 1968], No. 14626/68. Heading B7E. [Also in Divisions F2 and G2- G3] The core 32 and sheath 61 of a Bowden cable are connected respectively to the ends of arms 56, 57 pivoted at 54 and extend in curved manner to a servovalve of a pump control mechanism (see Divisions G2-G3) where a spring acts to bias the aims against stop 62. A control lever 55, also pivoted at 54, has a pin 64 which, upon movement of the lever away from the neutral position shown, eventually contacts one of the arms to displace the servovalve, the direction of displacement being the same whatever direction lever 55 is moved from neutral.</p> |
