Patent number: 4580728Abstract: A fuel injection nozzle having an outwardly opening valve needle to which a piston is connected and on which a cap is mounted. The cap encloses a damping chamber, which communicates in a throttled manner, via the play between the piston and the cap, with the flow course of the fuel. Oriented toward the cap is a blocking shoulder attached to the housing, which shoulder restrains the cap, after an undamped pre-stroke (h.sub.v), relative to the valve needle, which continues to move, its continued movement being damped thereby. A spring acts via a spacer body upon the cap, the spacer body keeping the cap at a distance from the blocking shoulder corresponding to the pre-stroke (h.sub.v) in the closing position of the valve needle. As a result, the prescribed set-point value of the pre-stroke (h.sub.v) can be adhered to very precisely.Type: GrantFiled: April 5, 1984Date of Patent: April 8, 1986Assignee: Robert Bosch GmbHInventor: Dietrich Trachte

Patent number: 4581642Abstract: The correction factor applied to a delayed television signal in a television noise reduction system and the complement of that factor applied to the undelayed television signal from which the delayed television signal is derived after averaging with the weighted delayed signal of an earlier of the preceding television frames, are modified in accordance with whether the source of the origninal television signals is or is not repeating at least one field of the television frames before going on to the next. The variation of the correction factor can also be made to depend on the number of repetitions of each frame. In an automatic system, operating in connection with a film scanner capable of scanning a motion picture film at different speeds (frames per second) to produce television signals in accordance with either the American or European television standard, the correction factor is set at the value 1 whenever a film frame is scanned for more than two half-frame television fields.Type: GrantFiled: September 14, 1983Date of Patent: April 8, 1986Assignee: Robert Bosch GmbHInventors: Dieter Poetsch, Gerhard Illetschko

Patent number: 4580445Abstract: The invention is directed to a method and an apparatus of determining whether the rotational speed of an internal combustion engine is attributable to a corresponding correcting quantity signal from an idle air charge control or whether an overrun condition exists. For this purpose, a variable supplementary signal is superposed on the correcting quantity signal of the idle air charge control. The mean value of this supplementary signal may be preferably zero. Taking the dead time of the internal combustion engine into account, the measured rotational speeds are correlated with the changes in the previously issued correcting quantity signals, and it is determined whether the engine is in the overrun mode of operation or idling. If an overrun condition is detected, an overrun recognition signal may be issued to initiate measures aimed at preventing the internal combustion engine from stalling, for example.Type: GrantFiled: January 31, 1985Date of Patent: April 8, 1986Assignee: Robert Bosch GmbHInventors: Helmut Janetzke, Helmut Kauff, Alfred Schulz

Patent number: 4579017Abstract: A restoring device for an adjusting element, which serves in particular for restoring a throttle device of an internal combustion engine. The restoring device has a first spring subject to bending, which is disposed on a bushing that is rotatably supported about a throttle valve shaft and with one end engages a step of the bushing, while the other end of the spring is hooked onto the housing on the throttle valve fitting. A lever is connected with the shaft. The first spring subject to bending acts in the restoring direction of the throttle valve. A second spring subject to bending is disposed in the bushing, one end of this spring engaging the bushing and the other end being supported on the lever. The spring force of the second spring subject to bending is less than that of the first such spring, so that the bushing, with a stop step, is rotated so far that the second spring has not influence in the restoring direction upon the throttle valve.Type: GrantFiled: June 18, 1984Date of Patent: April 1, 1986Assignee: Robert Bosch GmbHInventor: Hermann Nusser

Patent number: 4579145Abstract: A pressure control device, preferably for use in a control system of an automatic transmission of a motor vehicle, comprises a housing which accommodates a magnetic coil and an armature, and a control slide actuated by the armature and movable within a valve through which pressure medium to be controlled passes. A plunger carrying the armature is arranged coaxially to the magnetic coil within the housing and is supported at the both ends axially. A diaphragm spring is arranged at the end of the plunger facing toward the control slide. A pin loaded with the control pressure and arranged at the end of the control slide opposite to that facing the plunger acts on the control slide. A compression spring provided on the armature develops a force which acts against the force of the electric magnet and the hydraulic force which acts on the pin. The pressure control device is therefor suitable for controlling of considerably higher pressures and greater volumes of the pressure medium.Type: GrantFiled: May 31, 1984Date of Patent: April 1, 1986Assignee: Robert Bosch GmbHInventors: Heinz Leiber, Alwin Stegmaier

Patent number: 4580078Abstract: To correct the beam direction, and thus the color purity of color television tubes, particularly in tubes having fixedly secured deflection systems (10), the deflection field is, upon adjustment for color purity, additionally modified by introducing a unidirectional magnetic field extending with its field lines parallel to the z-axis of the tube. After adjustment to move a predetermined color, for example red, from non-deflected or hardly deflected central beam positions into the center of the CRT, the d-c unidirectional field is then disconnected, and the apertured mask demagnetized, as conventional. For demagnetization, the already present demagnetization coil (9) on the tube may be used, by applying a constant voltage thereto, for example of 12 V. The decaying demagnetizing field can be derived from a transformer connected to network power (FIG. 2) or through an oscillatory circuit formed by a charge capacitor (17).Type: GrantFiled: February 1, 1984Date of Patent: April 1, 1986Assignee: Robert Bosch GmbHInventor: Dieter Spannhake

Patent number: 4580220Abstract: A failsafe emergency operation device for the idling operation of motor vehicles, in particular for a digital idling charge regulation having a final control element triggered by an end stage circuit, which final control element, as a two-coil rotary adjuster, controls the cross section of an air bypass parallel to the throttle valve. A central computer (microprocessor, microcomputer) prepares a digital trigger signal for the end stage having a duty cycle which is variable depending upon the final control element position required. At the same time, at at least one position of the final control element, an end stage monitoring signal which is to be fed back is prepared and fed back to the computer, which via a separate shutoff stage for the end stage makes this end stage current-free whenever agreement does not exist between the two signals in terms of the duty cycle.Type: GrantFiled: July 21, 1983Date of Patent: April 1, 1986Assignee: Robert Bosch GmbHInventors: Gunter Braun, Wolfgang Kosak, Alfred Kratt

Patent number: 4578719Abstract: A conventional multiple recognition unit provides a multiple error signal whenever digitally coded television signals supplied in successive data blocks to the error recognition unit finds by reference to check-words that the error correction capabilities of the unit are exceeded in any data block. In order to determine when such multiple errors are related to faulty tracking, the multiple error signals are prolonged in duration, overlaps between the multiple error signal and a preceding prolonged signal are detected, and the latter are then integrated. The level of the integrated signal determines the likelihood or presence of tracking error.Type: GrantFiled: December 6, 1984Date of Patent: March 25, 1986Assignee: Robert Bosch GmbHInventors: Jurgen Heitmann, Rolf Loos, Peter Wagner
