Title: Active seat suspension control system and vibrometer therefor
Inventor: VAN GERPEN MARLAN WELBERT
IPC: F16F15/04
Filed: 1981-09-18
Granted: 1984-07-26
Abstract: A virbometer 16 has a mass 50 suspended for vertical movement by a light spring 82 so that the mass tends to stay at a constant height reardless of angulations in the ground over which the vehicle carrying the system is travelling. The vibrometer provides one height signal by way of a potentiometer 46 and a second potentiometer 40 provides a second signal representing of the drivers seat 12. An error signal formed by a comparator 44 controls a hydraulic double acting actuator 18 so as to make the seat 12 follow the mass 50 and accordingly tend to maintain a constant height in absolute terms. In order to prevent the system becoming unstable when the ground is very rough, the mass opens limit switches 20, 22 at upper and lower limit positions and, when either switch is open, a relay 98 drops out and a solenoid valve 24 disables the actuator by connecting the two inlets 62, 64 of the actuator cylinder 60 together via a slow resistor. The relay is also deenergized when the ignition switch 26 is off. The potentiometers 46, 40 are connected between two circuit arms 36, 38 and a variable resistor 54 in the energising circuit provides gain control, ie sensitivity control. Ganged resistors 110, 112 in the two arms provide stiffness control and a resistor 116 solely in the arm 38 adjusts the main seat height. The relay 98 is of a latching relay which is reenergized by a reset switch 28. Operations of this switch sets the gain control resistor 54 to minimum gain. In a preferred construction of the vibrometer, the mass is suspended from the end of a lever arm projecting from one end of a torsion rod having the other end fixed.

Title: Electronic control apparatus
Inventor: DIEPOLD-SCHARNITZKY RUDOLF
IPC: G01D11/24
Filed: 1982-04-30
Granted: 1986-09-11
Abstract: An electronic controller having a detachably mounted front panel unit on which display devices and control elements are arranged is disclosed. By means of the control elements, the process variables and the control parameters are changed incrementally. Values of the control parameter, process variables, and the selected control parameter are indicated by the display devices. To provide a compact, independent front panel unit which can be removed from the main housing of the controller for protection against unauthorized operation, the front panel unit is provided with a slave microprocessor which is connected via a plug-in connector to a master microprocessor in the main housing. Because the master microprocessor operates independently of the front panel mounted slave microprocessor, the front panel unit can be removed without affecting the operation of the controller.

Patent DE-3364465-D1 (DE)
Title: Apparatus for keeping the tension of metal strips at a constant level
Inventor: UMLAUF NORBERT
IPC: B65H20/06
Filed: 1983-03-02
Granted: 1986-08-21
Abstract: Strip processing lines require tension or back tension to be applied to the strip, as the case may be. These requirements are best met by the proposed chain bridle. The recoiling of adjacent slit strips on a tension reel will result in varying rewinding speeds and tensions due to the different thickness of the individual strands. Thick strands will be rewound too tight and thin strip too loose. Therefore, the chain bridle is installed before the tension reel to keep the tension of the various strands or a wide strip at a constant value. The strip (1) is clamped between two circulating chain systems (4a,4b), one arranged below and the other above the strip passline. One chain system (4b) is fixed, the other one (4a) is adjustable. The chain segments (4) of the chain systems (4a,4b) are provided with a covering and are moved parallel to the strip (1) through support rolls (5) and guide gibs (6a) with entry and exit guide curves (6) with the latter ensuring an adequate clamping pressure of the relevant opposite chain segments (4). The segment covering (7) may consist of an elastic coating (11) provided with additional shapes or profiled surfaces (12).
