Patent DE-19631281-A1 (DE)
Title: Method for stopping constant variable transmission vehicle
Inventor: JUERGENS GUNTER DR
IPC: B60K6/365
Filed: 1996-08-02
Abstract: The vehicle has a constant variable transmission (CVT) and a friction coupling (K1). During the stopping process, the gear ratio of the transmission, and the torque transmitted by the friction coupling are coordinated so that a specific torque is exerted on the output shaft (a). The transmission may have load branches with a neutral point, i.e. with zero transmission ratio between the input shaft and the output shaft. In this case the transmission ratio is taken out of forward drive shortly before stopping, so that a drive torque acts on the output shaft.
Patent DE-19631534-A1 (DE)
Title: System for continuous, non-chipping cutting of tubular workpieces
Inventor: FELDMEIER FRITZ DR
IPC: B23D21/00
Filed: 1996-07-25
Abstract: The system comprises rolls (1-1'') which are synchronously driven in the same direction and are provided with helical cutting edges (2-2''). There is also a feed device for the workpiece (3) which can be kinematically coupled to the rotation of the rolls so that the workpiece rotates against the direction of the rolls. At least one radiation source (5-5") is spaced out from the radially extending region of the rolls, sending a high energy beam of radiation (6-6") passing unhindered through the intermediate space between two adjacent rolls onto the surface of the workpiece. The beam provides a direct heating of the workpiece in the area where cutting will take place, the radiation source moving synchronously with the workpiece. Towards a the end of a designated distance the heating stops and the radiation source moves back to a rest position. The beam may be moved in the longitudinal direction of the workpiece and have a high energy radiance.

Patent DE-19654911-A1 (DE)
Title: Oscillator with feed back amplifier and tuner circuit
Inventor: BAYER STEFAN DIPL ING
IPC: B61L3/12
Filed: 1996-05-18
Abstract: The circuitry comprises an amplifier transistor (T5) stage driving a push-pull power output stage with two transistors (T7, T10) and associated resistors and capacitors.  The amplifier drives a tuned circuit consisting of a capacitor (Cx) and an inductor (Lx).  There is an emitter follower transistor (T9) stage between the driver amplifier and the power output section.  Another transistor (T9) is cut off as long as the emitter voltage amplitude of the emitter follower transistor (T6) remains low, due to a low initial AC voltages.  A transistor (T8) becomes conductive via a resistor (R14), and a current flows through diodes (D3, D4), limited by a resistor (R13), so that the diodes establish a working point, using a finite resistance.
Patent DE-19702383-A1 (DE)
Title: Road vehicle power steering control system
Inventor: SHIMIZU YASUO
IPC: B62D6/00
Filed: 1997-01-23
Abstract: The power steering system has a direction detector 1 that provides a signal that is summed 5 with the reference direction signal provided by a navigation system 4. The difference signal is received by the drive 30 and this determines the reference torque level required by the steering motor. Inputs are also provided based upon a speed sensor 12 and steering torque 10 and angle 11 sensors .  The amplitude and torque signals are monitored and interpreted as a means of detecting driver attentiveness. If a level is exceeded a vibration is transmitted as feedback.
