  • Patent number: 8490781
    Abstract: A transport container system for spectacle lenses includes a base container having first and second insert receptacles. A first pair of identical inserts for the first and second insert receptacles are provided and each insert has a spectacle lens receptacle for receiving a spectacle lens in a positionally oriented manner. The inserts are insertable into the first and second insert receptacles so that the geometrical centers of the spectacle lenses are arranged at a first distance from one another. A second pair of identical inserts differing from the first pair is provided for the first and second insert receptacles. The inserts each have a spectacle lens receptacle for receiving a spectacle lens in a positionally oriented manner and are insertable into the first and second insert receptacles so that the geometrical centers of the spectacle lenses received therein are arranged at a second distance different from the first distance.

  • Patent number: 6349708
    Abstract: A method is provided for controlling an internal combustion engine with a mechanically driven supercharger which can be switched on and off by means of a clutch and is arranged in a charge-air line. A bypass-air line with a bypass-air control element connects the intake and delivery sides of the supercharger. A throttle valve is situated upstream of the supercharger or downstream in the charge-air line. The clutch and/or the bypass-air control element are controlled with specifiable values for a degree of opening and/or a switching state of the clutch, and, in a specified part-load range of the internal combustion engine, the bypass-air control element closes the bypass-air line when the clutch is open.

  • Patent number: 6227180
    Abstract: In an arrangement and method for controlling a supercharged internal combustion engine having a charger arranged in the air intake duct and a catalytic converter arranged in the exhaust duct, with a secondary air duct including a control valve extending from a point of the intake duct downstream of the charger and upstream of a first throttle member to a point of the exhaust duct upstream of the catalytic converter, a second throttle member is arranged in the intake duct upstream of the charger and the throttle members and control valve are controlled by a control unit in such a way that sufficient air is supplied to the exhaust duct upstream of the catalytic converter such that, during engine warm-up, combustion takes place in the catalytic converter causing rapid heat-up of the catalytic converter.

  • Patent number: 5937831
    Abstract: In a method of controlling a supercharged internal combustion engine of a motor vehicle wherein the engine includes a supercharger operated by the engine by way of a clutch and a return air flow duct including a return air flow control value is provided for returning air from the charger outlet side back to the charger inlet side and wherein the engine includes an engine control unit for controlling operation of the engine on the basis of a plurality of sensor values, the return air flow control valve and the charger clutch are controlled depending on operating parameters of the engine and of the motor vehicle so as to achieve various engine operating conditions and a certain vehicle behavior under certain vehicle operating conditions.

  • Patent number: 5706790
    Abstract: In an arrangement for controlling the charging air flow of a supercharged internal combustion engine which has an intake air pipe with a throttle valve connected to the discharge side of a supercharger and a communication pipe extending from the intake air pipe to the engine exhaust manifold for supplying air to the engine exhaust gas, an air supply pipe extends from an air filter housing to the supercharger suction side and a return air duct including a flow control valve extends from the intake air pipe to the air filter housing for recirculating air to the supercharger suction side through the air filter housing under the control of the flow control valve for controlling the air pressure in the engine intake air pipe.

  • Patent number: 5613478
    Abstract: The invention relates to a device for controlling the air flow of a supercharged internal combustion engine with a supercharger to deliver charge air from a suction line located upstream of the supercharger through a charge air line located downstream of the supercharger to the internal combustion engine. The suction line includes an intake and a recirculating line with a recirculating valve located between the charge air line and the suction line. The recirculating line between the recirculating valve and the suction line is formed by a line section that terminates in the suction line of the supercharger downstream of the intake.

  • Patent number: 4373337
    Abstract: An internal combustion engine with spark ignition having an exhaust gas turbocharger. Supercharger air from the turbocharger is conveyed through a charger air line or pipe to an intake manifold of the internal combustion engine. A throttle valve is provided for the power control of the engine in a path of the supercharger air, especially at an inlet to the intake manifold. A bypass air line or pipe is connected to the charger air line or pipe, with the bypass air line extending to a position upstream of the turbocharger. A further throttle valve is arranged at the bypass air line with both throttle valves being mechanically connected with each other in such a manner that one throttle valve closes when the other throttle valve opens, and vice versa.
