Patent DE-19537025-A1 (DE)
Title: Synchronous feed and withdrawal of material for machines
IPC: B21C47/00
Filed: 1995-10-05
Abstract: The speed of the material carrier or the speed of the material processor are constantly synchronously adjusted to each other. Consequently, care is taken of the material and finished product, and also of the machines, tools and winding units. A distance measurement sensor (3) is located between a winding unit (1) and a machine (2). The sensor determines the distance discrepancy of the material away from an ideal line (4) and, using this value, sets an absolutely synchronous adjustment of the material speed to the working speed of the machine.

Patent DE-19611944-A1 (DE)
Inventor: HANF PETER DIPL ING
IPC: H04L69/40
Filed: 1996-03-26
Abstract: The invention relates to a process for determining potential shifts between electronic modules in a wire bus network or for determining the level of agreement of their respective communication operating levels in network connection. The bus medium comprises at least one wire which is galvanically connected to the electronic modules. According to the invention, an offset voltage is added in at least one bus subscriber (test subscriber) on the transmission side to (at least) one (of the two) dominant normal source levels and a test message is sent by the test subscriber in that state onto the bus network. The source level is thus modified in a predetermined way. Depending on whether the (at least) one (of the two) dominant source levels is lowered or raised by the adjustable offset voltage, the subscriber affected by the (reference) potential error gains or loses his reception capability. This is evaluated. The device comprises co-operative potential control means connected or capable of connection to the transceiver function of a bus subscriber and together with those control means forms at least one controllable voltage source at least in relation to parts of the transmitter/receiver system, said voltage source allowing modification of a dominant source level during transmission and/or at least one discriminant signal level in reception.

The reference object is fixed against the tooth by e.g. adhesive or a holder.
Patent DE-19620883-A1 (DE)
Title: Control system for internal combustion engine
Inventor: UNGER HARALD
IPC: F02D9/02
Filed: 1996-05-23
Abstract: The power output of the internal combustion engine is controlled by varying the timing of opening and closing of the inlet and exhaust valves. Reducing the period of opening of the inlet valve, especially earlier closing, may reduce the amount of mixture drawn into each cylinder on the induction stroke. Power generated by the engine is reduced with minimum wiredrawing of mixture though narrow passages. The throttle valve is retained for use during overrun and braking periods, to enable recharging of the vacuum reservoir in the usual way.

Title: Control unit for diesel engines running on oil or fat
Inventor: LOHMANN GEORG
IPC: F02M31/10
Filed: 1996-08-30
Abstract: The engine runs on animal fat or on vegetable oil and uses a special fuel for starting while the fat or oil is still very viscous. After starting, the engine is automatically switched over to the use of fat or oil. This is controlled by a vacuum switch and is also dependent on the viscosity of the fat or oil. The components (1-6) of the control system, which are heated and come into contact with the fat or oil are mounted in a housing so that the parts remain warm and the use of starter fuel is reduced. Any surplus fuel fed to the engine is returned and flows to an intermediate tank which contains a contact making float.
