Abstract: 1,157,535. Carburetters. FORD MOTOR CO. Ltd. Feb.15, 1967 [Feb.28, 1966], No.7168/67. Heading F1B. In a carburetter a single thermo-responsive bi-metallic element 56, Fig. 4 controls both a choke valve 16 and the quantity of fuel discharged from an accelerating pump 20 Fig.2. Operation: Before cranking a cold engine a pedal (not shown) is fully depressed to fully open a throttle valve 50 by clockwise rotation of a shaft 24. This causes a fast idle adjusting lever 52 to rotate counter-clockwise so that a screw 54 moves away from a cam 68. The cam 68 is then free to be moved by the thermally-responsive element 56 so that a portion 72 is in the path of the screw 54 with the choke valve 16 partially closed in the Fig. 4 position. Concurrently a projection 27, Fig. 2 abuts a projection 48b of an arm 48 to pivot it counterclockwise so that a latch portion 48a is moved to permit a lever 36 to be moved in unison with the throttle lever 26 via a spring 42. An arm 38 is moved by the lever 36 and a full stroke of the pump 20 discharges the larger volume of fuel (e.g. 2¢ ccs) into the passage 14. After releasing the pedal the screw 54 abuts portion 72, to prevent the shaft 24 from returning to its original position. The projection 36a does not contact the projection 48b and the lever 36 remains unlatched and free to rotate with the shaft 24 and as long as the engine remains cold the pump 20 discharges a fuel volume dependent on the throttle opening. At normal operating temperature the element 56 causes the cam 68 to rotate so that it is not contacted by the screw 54 and the projection 28 is biased into abutment with the stop 32 when the engine is idling. Concurrently the projection 36a contacts the projection 48b to rotate arm 48 counter-clockwise hooking the latch 48a over the lever 36. When the pedal is partially depressed after the engine has reached normal temperature the latch portion 48a only permits rotation of lever 36 until portion 48a prevents further rotation. This gives a small discharge (e.g. 1 cc. ) from pump 20.  Rapid acceleration is achieved by full depression of the throttle pedal since the lever 26 unlatches  lever 36 as in cold starting thus allowing full accelerator pump discharge. 1,157,538. Axial-flow fans. W.SEEBER. April 12, 1967 [April 12, 1966], No. 16773/67. Heading F1C. ring 3 to the inner ring 4, of the blades 1, the webs being joined together to form a continuous radial intermediate wall 5 of wavy form when viewed radially, Fig. 4. This prevents deformation of the hub by the simultaneously applied thermal and mechanical loading occurring in the use of the fan on a motor vehicle engine. The annular spaces 6, 7 are provided with axially-extending connecting webs 8, 9 at those points where the intermediate wall 5 has its deepest recesses, and axiallyextending connecting webs 10 at those points where the radial centre lines of the blades 1 pass through the rings 3,4. Gussets 17 are provided between the ring 4 and the mounting flange 13 of the hub. The mounting flange 13 lies in the plane 14 containing the centre lines of the blades 1, and the gussets 17 are located adjacentthe leading and trailing edges 18 of the blades.
