Abstract: An electrical driving system for the outer rearview mirrors of a vehicle erects or folds the mirror bodies by an operation switch for rotating the incorporated motors normally or reversively. The system comprises a momentary operation switch (10), normal and reverse relays (Ry₁ Ry₂) and limit switches (51 to 54) for disconnecting the motors (M R , M L ) and self-holding circuits of the relays from a power source (B+, E) independently of one another by detecting the erected and folded states of the mirrors. When the normal or reverse relay is rendered operative by the momentary operation switch, the incorporated motors are driven to cause rotation of the mirrors. The mirrors are stopped independently with disconnection of the respective motor circuits caused by the action of the limit switches when they reach the erected or folded state.

Abstract: A method of feeding a four-stroke reciprocating-piston engine is described in which the cylinder is not charged until the compression cycle, any escape of the charge fed in being prevented during this compression cycle. In this way a high flow rate and strong charge swirling is ensured even up to the instant of charge ignition. In an internal combustion engine with lift valves, the inlet lift valves are opened only until the charge required for the particular operating point is in the cylinder. To this end the opening time, the closing time and the maximum valve lift of the valve lifting cam are adjusted according to the particular operating point. The lift valves may be operated magnetically or hydraulically, but a solution in the form of a camshaft adjustment combined with a hydraulic valve lift control is also proposed. <IMAGE>

Abstract: A two way closed-centre solenoid valve apparatus comprising a housing (32) defining a flow path interconnecting an inlet port (16), an outlet port (50) and a vent port (72) and a valve (14) in the flow path. In a first position, the valve (14) closes communication from the inlet port (16) to both the outlet port (5) and the vent port (72); in a second position the valve opens communication between the inlet port (16) and only the outlet port (50), and in a third position it opens communication between the outlet port (5) and only the vent port (72). The valve (14) defines a predetermined sealing area upon which fluid pressure is effective to urge the valve from the fluid position towards one of the second and third positions. The apparatus includes input means (80-92) for selectively moving the valve from the first position alternatively to either one of the second and third positions. The apparatus also includes feedback means having a first feedback area (128) significantly exceeding the predetermined sealing area and arranged to urge movement of the valve means from either the second or the third position towards the first position in response to fluid pressure effective thereon, and means (124) communicating fluid pressure from the outlet port to the first feedback area (128) as a first time derivative of the fluid pressure level at the outlet port to act upon the first feedback area.

Abstract: The output voltages (Ud1, Ud2) of two D.C. choppers (7, 9, 72, 92) connected in series on the input side are to be controlled. For this purpose, the sum voltage (U SIGMA  = Ud1 + Ud2) and the error voltage (U DELTA  = Ud1 - Ud2) of the output voltages (Ud1, Ud2) of the D.C. choppers are formed as secondary controlled variables. The sum voltage (U SIGMA ) is compared to a desired value of the sum voltage (U SIGMA Soll), and fed to a sum-voltage controller (10). The error voltage (U DELTA ) is compared to a desired value and fed to an error-voltage controller (11). The output signals of the two controllers (10, 11) are added or subtracted from one another and used in this way to form the pulse duty factors (a1, a2 and a11, a12, a21, a22 or a1H, a1T, a2H, a2T) for controlling the D.C. choppers. <IMAGE>
