  • Incinerator for combustible refuse
    Patent number: 4009667
    Abstract: An incinerator having a variable speed auger to continuously feed refuse into and through a combustion chamber and into a water filled ash receptacle. Preheated combustion air is supplied through tangential openings in and along the combustion chamber walls, with the hottest air supplied at the combustion chamber inlet. The auger has a water cooled hollow shaft and a heat resistant flight concentrically spaced away from the auger shaft by support members. The pitch of the auger flight gradually decreases from the inlet end to the discharge end of the combustion chamber. The exhaust gases pass through heat exchangers and dust collectors before being emitted from the incinerator. A portion of the exhaust gas is recirculated by a blower to an air curtain in the front of the inlet unit to preheat the entering refuse.

  • Air control valve for exhaust gas purifying apparatus
    Patent number: 4009986
    Abstract: In an exhaust gas purifying apparatus which includes a reactor in the exhaust line of an internal combustion engine there is provided a heater burner to which there is delivered an air-fuel mixture and which heats the reactor for rapidly bringing it to operating temperatures when the engine is started. In the air conduit through which combustion air for the air-fuel mixture is delivered to the burner there is provided a valve controlled in such a manner that the flow rate of combustion air remains constant and is thus independent of the said counterpressure at the heating burner and the output delivery of the air pump driving the combustion air.

  • Apparatus for the detoxification of exhaust gases
    Patent number: 4007719
    Abstract: An apparatus for the detoxification of exhaust gases of an internal combustion engine having a fuel metering mechanism, such as a carburetor, which meters out fuel corresponding to the air quantity, is described. An air quantity measuring device is provided which controls the metering mechanism so as to achieve a slightly enriched fuel-air mixture. Thus, the air number (.lambda.) is initially maintained at less than 1, the air number 1 designating a stoichiometric fuel-air mixture. Secondary air is admitted via a secondary air pump, an oxygen sensor being disposed on the exhaust side, until such time an optimum of fuel-air mixture is reached. The secondary air is admitted into the suction tube of the internal combustion engine downstream of the air measuring device.

  • Fuel metering system for internal combustion engines
    Patent number: 4007720
    Abstract: A fuel metering system for an internal combustion engine meters out fuel in dependence on the pressure in a fuel supply container. This pressure is controlled by a valve or valves which provide communication with different regions of the induction tube of the engine. The control valves are electro-magnetic valves under the control of a suitably processed and amplified signal from an exhaust gas measuring probe which determines the concentration of oxygen.

  • Fuel injection system
    Patent number: 4007722
    Abstract: A fuel injection system for externally ignited internal combustion engines in which a fuel metering and distributing valve is controlled by an air sensing element disposed in the air suction tube of the engine and by structure which is adapted to alter the restoring force exerted on the air sensing element through the fuel metering and distributing valve. The noted structure includes a control pressure conduit, a pressure control valve connected to the control pressure conduit and a relief valve also connected to the control pressure conduit and connected to the fuel metering and distributing valve. The relief valve includes a sleeve valve and a throttle which is controlled by the sleeve valve. The throttle opens into a pressure chamber disposed on one side of a slide member of the fuel metering and distributing valve. This slide member exerts the restoring force applied to the air sensing element.

  • Control installation for exhaust gas recycling
    Patent number: 4005691
    Abstract: An improved control installation for internal combustion engines having exhaust gas recycling is described. The installation includes a suction tube, a throttle flap valve mounted within the suction tube, an exhaust gas pipe, an exhaust gas recycling valve and a return line leading from the exhaust gas pipe to the recycling valve and from there back to the suction tube downstream of the throttle flap valve. The improvement comprises a bypass line which extends from the suction tube upstream of the throttle flap valve to the recycling valve and back to the suction tube downstream of the throttle flap valve. The air that passes through the bypass line serves to cool the recycling valve. In addition, the bypass line serves as a conduit for air to the engine during idling operation.

  • Apparatus for continuous cleaning of a honing tool
    Patent number: 4004375
    Abstract: The honing tool in a centerless honing apparatus is held in an oscillating head and is pressed against the workpiece transported by rotating rollers. The region of contact between the honing tool and the workpiece is immersed in a flushing liquid which serves to dislodge and remove abraded material from the contact surface of the honing tool. An ultrasonic generator is located near the honing tool and its transducer portion extends into the flushing liquid. The ultrasonic vibrations are transmitted by the flushing liquid to the honing tool, imparting thereto ultrasonic oscillations in a direction transverse to the rotational axis of the workpiece. The liquid also transmits ultrasonic vibrations directly to the contact area and to the embedded abraded material, thereby loosening it and permitting entrainment by the flushing liquid.
