Abstract: A fuel injection valve for an internal combustion engine has a main fuel valve formed by a needle urged against a valve seat by a spring and also includes a solenoid to pull the valve needle away from the seat for fuel metering purposes. In addition, the valve has an extension in which a pestle with two enlarged ends is axially carried in two spring support cups. The enlarged ends of the pestle also act as valves in such a manner that even low fuel-flow causes a fluttering of the pestle, resulting in good fuel atomization.

Abstract: What follows is a description of various exemplary embodiments of a fuel injection system for an internal combustion engine with exhaust gas recycling controlled by a throttle valve situated in the suction tube of the system. The throttle valve is in turn controlled by a servomotor having a displaceable piston connected to the throttle valve. The piston is displaceable against a variable restoring force exerted against it and produces displacements of the throttle valve between two positions, one corresponding to a fully opened position of the throttle valve and closed exhaust gas recycling line, and the other corresponding to a substantially closed throttle valve.

Abstract: The present invention relates to reciprocal junction devices between independent coaxial lines and concentric coaxial lines. As many elementary junctions as there are independent lines, less one, are required. Each elementary junction involves a two-wire line zone and two parts which establish a progressive transition between the two-wire line and, at one end, the independent coaxial line and, at the other end, the concentric coaxial lines.

Abstract: The roller shaft which actuates a pumping element in a fuel injection pump is secured against unintentional release during transport by elastic elements, preferably spring wire parts, whose one end engages a stationary portion of the fuel supply pump and whose other end engages a recess or cutout in the roller shaft and cooperates with a shoulder or stop therein to prevent unintentional drop-out while permitting a normal reciprocating motion after installation. Suitable openings and grooves provided in the roller shaft guide can hold and orient the spring wire.

Abstract: A ring spinning or twisting machine has rotating rings which are equipped with metallic flanges. Each ring has an associated permanent magnet device which can be moved to the vicinity of the flange so that the magnetic field interacts with it and generates eddy currents which tend to decelerate the rotating ring. The permanent magnets are mounted on a common sliding rod which is actuated by a servomotor. The displacement is such that each magnet moves substantially parallel to the plane of the flange and may occupy a position where the magnetic field is laterally adjacent to the flange and does not interact with it.

Abstract: A spinning machine with a plurality of spinning locations or stations is equipped with automatic or semi-automatic spool-changing mechanisms. The machine also has a servicing device, designed for travel along the machine and for repairing thread breakages at some particular spinning location. The presence of this servicing device or carriage at a spinning location would interfere with the operation of the spool-changing mechanism. A controller delivers signals to an appropriate receiver in the servicing device and causes it to depart to a neutral zone at the end of the machine.

Abstract: The invention relates to packaging machines wherein a web of flexible material is transformed into a tube, filled, sealed and discharged onto a conveyor mechanism, the completed package being then transported to a positioning device where it is deposited in a shipping case.The packaging and shipping case loading machines are coordinated by a plurality of sensor means which preclude the necessity of an operator having to start and stop the machines when a filled shipping case is removed from the platform and supplanted by an empty one.

Abstract: A fuel injection control apparatus provides electrical pulses whose length determines the amount of fuel supplied to the injection valves of the engine. These pulses can be extended by a circuit including a temperature dependent resistor when the engine has not reached operational temperature. This same mechanism is utilized to lengthen the fuel delivery control pulses even when the engine is warmed up, i.e., under hot-start conditions, by connecting a switching transistor in series with the temperature-dependent resistor that monitors the engine temperature. If, while the engine is hot, the starter motor is being cranked longer than a predetermined length of time, the switching transistor turns off and causes the fuel injection pulse to be lengthened, thereby supplying additional fuel to the engine to overcome a possible fuel vapor lock.

Abstract: Method and apparatus for micro-finish machining of cylindrical or conical surfaces on workpieces, and in particular the raceways of cylindrical or tapered roller bearings using a honing tool. The honing tool is subjected to two distinct motions in a direction parallel to the transverse direction of the surface of the raceway to be machined. One of the motions, the first oscillation, has a short stroke relative to the width of the surface to be machined, while the other motion extends over the entire width of the surface to be machined. The two motions are superimposed for achieving a surface contour of the raceway so that during full loading of the bearing, the raceway is subjected to approximately uniform surface pressure over the entire width of the raceway.

Abstract: An internal combustion engine which is provided with an exhaust gas treatment system, such as thermal or catalytic reactors, includes a primary regulating system for admitting fresh air to the exhaust system for the chemical processes taking place in the reactors. This fresh air regulation depends on the engine rpm and on the induction tube pressure. There is also provided a secondary air control system, including a three-way valve and an electronic controller and an oxygen probe, located in the exhaust manifold. The probe supplies the controller with a signal related to the oxygen concentration in the exhaust gas and the controller uses this signal to actuate the three-way valve which admits either induction tube pressure or, alternatively, exhaust system pressure, to a control chamber in the primary regulating system, thereby influencing the quantity of fresh air supplied to the exhaust manifold of the engine.
