Title: Carburetor with anti-running-on control
IPC: F02M3/08
Filed: 1972-10-10
Abstract: 1348965 Spray carburetters FORD MOTOR CO Ltd 10 Oct 1972 [29 Nov 1971] 46608/72 Heading F1B A carburettor has a throttle 22 rotatably mounted across an induction passage and movable from a closed first position 34 through a second open idle speed position 36 to a wide open throttle position, control means to move the throttle valve to the first and second positions which includes first means 40, biasing the throttle to the closed anti- "running-on" position, second means biasing the throttle to the second position and engine manifold vacuum sensitive means operable on engine shutdown to initially move the throttle valve to the first closed position and subsequently permit return throttle movement to the second position for starting. When the engine is cranked the turning of the ignition key energizes solenoid 98 to position valve 92 as shown to admit manifold vacuum to chamber 48 from where it bleeds via orifice 64 into chamber 46 until the vacuum levels equalize. Throttle valve 22 and plunger 56 remain as shown. If the engine is shut off by turning the ignition key solenoid is de-energized and valve 92 bleeds line 52 and chamber 48 to atmosphere. As soon as the engine stops the vacuum in reservoir 46 is slowly bled to atmosphere and the delay e.g. five seconds, permits the vacuum in servo 46 to retract diaphragm 50 and plunger.56 to permit spring 40 to close throttle 22 to prevent "running-on".

Abstract: 1,001,856. Electric meters. PENTACON DRESDEN KAMERA-UND KINOWERKE VEB. Dec. 19, 1962, No. 47893/62. Heading G1Q. [Also in Division G2] In an electric metering device the meter pointer may be manually deflected to a predetermined point by a setting lever, mechanically coupled to a control lever operative to tension the restoring spring of the movement or to rotate the entire movement against a return spring and at the same time to insert a stop arm into the path of the meter pointer, to set the latter manually to a required position. In a photographic camera, the moving coil 11 of a meter movement 5 excited by the output of a photo-cell (not shown) deflects a pointer 7 over an aperture scale 12 and aslo deflects a diaphragm 8 having a shaped opening 13 in the light path of the objective lens 14 to regulate the aperture thereof; window 21 in the principal plane having opposed tabs 21a obscuring marginal rays at reduced aperture. The free end of the return spring 4 of the moving coil rests on the cranked end of control lever 2 rotatable about pivot 3 against coupling spring 16 impelling the lever against zero adjusting stop 9. A setting bellcrank lever 10 pivoted at pin 18 and adjustable over aperture scale 17 carries a stop arm 6 capable of arresting the deflection of pointer 7 and a pin 19 engageable with a curved face 20 of the control lever. In position A (automatic) on scale 17, pin 19 is disengaged from lever 2, which is held by spring 16 against stop 9 and the return spring 4 is tensioned to correspond to zero pointer reading for zero excitation, so that excitation from the photo-cell positions the diaphragm 8 in conformity with the incident light. In manual operation, lever 10 is set to a desired aperture on scale 17, and pin 19 lifts lever 2 against spring 16 and return spring 4 to tension the latter, so that pointer 7 lies against arms 6 for any excitation from the photo-cell; its position and that of diaphragm 8 corresponding to the manual aperture setting. In a modification (Fig. 2, not shown) the entire moving coil mechanism and its magnet is rotatable by mechanical coupling with the control lever, against a return spring secured to a fixed member.

[Classes 83 (ii) and 83 (iv)] Soldering.-The metal base is united to the metal bulb of an electric discharge tube by inserting it therein and then dipping both parts into a bath of molten metal or alloy, the melting point of which is above 500‹ C., one or both of the parts being cooled during and /or after immersion. A flanged base 1b is inserted in a plain or shouldered metal bulb 1a, and is held on a water cooled plunger 4 by a water cooled sleeve 10 which is pressed down to immerse the ends in a bath 2 of molten metal such as copper, silver, nickel or iron. When the parts are kept cool during immersion, the molten metal may have a melting point equal to or higher than that of the parts. Cooling of thin material may alternatively be effected by spraying with air or water after immersion. The bath is contained in a crucible 3 such as of alundum electrically heated by a coiled molybdenum strip 6 surrounded by a heat insulator 7 of aluminium oxide or fire clay in a jacket 7a, the whole being enclosed in an asbestos filled jacket 8a. Hydrogen may be introduced through a pipe 9 and also through a tube 14, a jet of air or neutral gas being blown by an ejector pipe 11 into the outflow pipe 13 so as to prevent damage to the parts by the hydrogen flame. The hydrogen atmosphere may be combined with or replaced by a flux such as borax which may float on the surface of the bath. A wire or sheet of low melting point alloy may be placed between the parts. In another form, the parts may be galvanically coated with a metal of lower melting point such as copper, the parts being then heated either previously or during immersion so that the coating diffuses into the surface layers of the parts to ensure a good joint, or the coating may be thick enough to form a layer between the parts.
