Patent DE-19539628-A1 (DE)
Title: Supply of granular raw material to a glass furnace
Inventor: HORN LARRY L
IPC: C03B3/00
Filed: 1995-10-16
Abstract: Solids transporter for feeding a reactor with granular material consists of a reciprocating plate with a frame which receives material from a chute at one end and delivers it into the reactor at the other end. The installation is fitted in front of an opening in the reactor wall and is supported outside it. The transporter frame, which securely closes the opening into the reactor, is water-cooled. The transporter itself maybe moved out of the feeding position on its supports. Inclination and reciprocating amplitude of the feed plate, which is also water-cooled, are continuously variable through its connecting links. The reciprocating linkage is motor driven, and whilst principally moving the plate in the transport direction also turns it in a horizontal plane.  The installation is partic. designed as a feeder for supplying raw materials into the melting furnace of a plate glass plant.

Title: Field-oriented regulation method for electric induction motor or generator
Inventor: BAUMANN THOMAS
IPC: H02P21/16
Filed: 1995-10-25
Abstract: The regulation or control method uses a flux regulator supplied with a control error (e) which is fed directly or indirectly to an integrator (30) providing an output signal representing the rotor time constant (Tr(t)), or the variation in the rotor time constant relative to a base rotor time constant.  Preferably, the sign of the rotor time constant variation is determined from the sign of the regulation error fed to the flux regulator and the sign of the output from the torque regulator, or the direction of the variation in the motor or generator revs.

Patent DE-19548684-A1 (DE)
Title: Exhaust-related malfunction of vehicle detecting and documenting method
Inventor: DENZ HELMUT DIPL ING
IPC: F02D45/00
Filed: 1995-12-23
Abstract: The method employs on-board diagnosis using a sensor and a switch unit to light a warning lamp in dependence on a predetermined number of driving cycles (1-7, etc.). Warning signals are also stored in a fault memory. To exclude error messages caused by empty fuel tank, the fuel level is also measured and memorised.  Each error message arising during any cycle is immediately recorded together with the fuel level. In subsequent cycles an error message is terminated and the memory erased only if the fuel level exceeds a predetermined value which was not attained in the preceding cycle.

Patent DE-19649920-A1 (DE)
Inventor: HIDDESSEN RALF
IPC: F15B11/068
Filed: 1996-12-02
Abstract: The valve comprises a housing with first and second apertures connected by a channel together with a piston (2) moving forwards and backwards between closed and open positions. The piston in the closed position works in conjunction with a valve seat (1c) and thereby closes the channel. A device is provided for maintenance of a low pressure medium flow, during the closed position of the piston, between an area with high pressure on the one side of the valve seat and an area in which pressure is building up on the other side of the valve seat. A spring component (5) impels the piston into the closed position. The piston has effective surfaces (2c-f) exposed to the high pressure and to the pressure which is building up. These surfaces produce force components, which impel the piston into its opening and closed positions. The piston moves into the opening position when the difference between the high and the building-up pressure is less than a threshold value.
