Title: Pulse amplifier for the time service technology
Inventor: DRAGOTIN MARIA DIPL ING
IPC: H03K17/785
Filed: 1986-12-10
Abstract: Positive and negative time pulses are transmitted on a two-wire line (pulse line) for clock control. The pulse amplifier exhibits an input circuit (ES1, ES2, ES3) which can be matched to the pulse line (IL) and which is in each case followed by a DC-isolation stage for the positive and negative time pulses (ZIp, ZIn), which isolating stage is formed by optocouplers (OK1, OK3; OK2, OK4). The optocouplers (OK1-OK4) are followed by a pulse amplifier stage (VER) having in each case one input for the positive and negative time pulses. The pulse amplifier stage exhibits simple power MOS transistors which are driven by the optocouplers (OK1-OK4), the power transistors being formed by FET transistors (LT1-LT4) arranged in a bridge circuit. The power transistors (LT1-LT4) are operated independently of the operating voltage (UB), which can exhibit a value of 12-60 V, an auxiliary voltage (gate-source modulation voltage), which is approximately 10 V, being applied to the power transistors (LT1-LT4). Furthermore, a quick-response overload protection circuit (ÜSS) is allocated to the power transistors (LT1-LT4). <IMAGE>

Patent DE-3707855-A1 (DE)
Inventor: DIETRICH RAINER DR
IPC: B22D11/06
Filed: 1987-03-11
Abstract: If a liquid metal oxide is fed to the nip of an inwardly cooled pair of rolls to cool and solidify, the rolls are subjected to a great material fatigue because of the constantly changing high heat stresses. A configuration of the rolls with few notches can be achieved by an approximation of the contour of a spherical hood. This is achieved in that each of the rolls (1,2) is designed as a truncated conical section, in that adjacent to the base (9,10), exhibiting the greater diameter of each truncated conical section a cylindrical section (5,6) with the diameter of the base (9,10) and a substantially open front surface (23) is provided. Each truncated conical section is closed, by a plane wall, on the front surface (7,8) with the smaller diameter.

Inventor: AGAR DAVID DR
IPC: B01D53/86
Filed: 1987-12-29
Abstract: For the removal of nitrogen oxides from waste gases by selective catalytic reduction with ammonia, ammonia is fed at intervals to the waste gas stream fed to a reaction zone which contains catalysts. The waste gas is fed to the reaction zone with periodic alternation in opposite directions of flow, the waste gas being fed, at the start of each period, together with a quantity of ammonia which is in excess of that stoichiometrically required for the reduction of the nitrogen oxides. The ammonia feed is stopped before unconverted ammonia leaves the reaction zone together with the waste gas. The direction of flow of the waste gases through the reaction zone is reversed at the latest when the NOx content and/or the NH3 content of the waste gas exceeds a predetermined set value.
Patent DE-3804975-A1 (DE)
Title: Spring for a setting device
Inventor: BODENHAUSEN ECKHARD DIPL ING
IPC: F02M19/12
Filed: 1988-02-18
Abstract: There are setting devices in which not only a prescribed resetting force but also a prescribed frictional force is required. By means of axial bracing of a spring (7) by means of a region (27) in which the windings (22) are not in mutual contact, a predeterminable, constant pressure is provided in a region (24) in which the windings (22) are in mutual contact. As a result of this pressure, the spring (7) generates a frictional force in opposition to a twisting of the spring (7). The frictional force is independent of the resetting force of this spring (7). By means of the spring (7) according to the invention, the resetting force and the friction force can thus be generated using only one component but nevertheless predetermined independently of each other. In a throttle device of an internal combustion engine, for example, the spring serves to reset a throttle flap and for generating a frictional force in the case of displacement of the throttle flap. <IMAGE>

Title: Device for automatically retracting a safety belt
Inventor: GRUENER PETER

Filed: 1988-02-18
Abstract: A device is described for automatically retracting a safety belt, in the case of which a strong retraction spring (22) and a weak comfort spring (18) are connected in series via a common spring box (20).

Locking is carried out by means of a rocking lever (32) which comes to rest against the outside circumference of the spring box (20) and interacts with noses (44) of the spring box (20). A cam plate (48) which is carried by a driving plate (46) releases the lock when the bolt is unfastened. <IMAGE>
Patent DE-3807375-A1 (DE)
Title: Device to measure the density of fluids by means of vibration systems
Inventor: BECKER WOLF-JUERGEN PROF DIPL
IPC: G01N9/04
Filed: 1988-03-07
Abstract: The density measurement is achieved by measuring the changes in frequency, accompanying changes in density, of an electromechanical vibration system exposed to the mass forces of the fluid to be determined. This vibration system is excited into resonant vibrations with the aid of an electronic amplifier, the vibration system forming, together with a transmission transducer and a receiver transducer, the positive feedback network or the external feedback of an electromechanical oscillator. The amplifier is designed as a phase-locking loop, which consists on the input side of a phase detector, a subsequent low-pass filter or PI-controller and, on the output side, of a voltage- controlled oscillator. The phase-locking loop is terminated with an internal feedback from the output of the voltage-controlled oscillator to one input of the phase detector; the second input serves as amplifier input for the external feedback. A frequency-independent phase shifter in one of the two feedback paths compensates the phase shift due to the losses in the electromechanical vibration system and takes into account the phase position of the input signal for the phase detector. By this means, the properties of the vibration system and the amplifier do not enter into the measurement of the resonant frequency.
