Title: Testing protected electrical loads in vehicle electrical network - measuring voltages across load protection devices, e.g. fuses, and comparing with stored permitted values
Inventor: ROHDE WOLFGANG ING GRAD
IPC: G01R31/00
Filed: 1991-09-18
Abstract: The method involves measuring the voltage across a resistance in series with each load. This is dependent on the current drawn by a switched-on load and is compared with a load-specific permitted value. A display is activated if the voltage is out of range. The resistance of the device protecting each load is used as the measurement resistance for that load. The current flowing through each protection device is derived from the corresp. voltage and compared with stored permitted values. ADVANTAGE - Enables load testing without introducing additional resistances into network.

Title: Moistener preparation system for offset printing - has reservoir which can be supplied with water and alcohol, with additive and amount of water flowing measured by water meter depending on filling level position
Inventor: CLAUDITZ DIETER
IPC: B41F7/32
Filed: 1991-11-04
Abstract: The alcohol and additive amounts are dosed by respectively assigned pumps (21, 22). The additive dosing pump (22) at least, is connectable to an exchangeable drum (17a), and can be activated proportionally to the amount of water fed in to the reservoir (1). A control unit (25) is provided, by which, during an exchange of a drum, a medium amount value to be dosed, depending on the amount of running water fed in to the reservoir, is storable. The dosing pump (22) assigned to the relevant medium is activated depending on the amount value stored by means of the control unit, after the resulting drum change. The additive dosing pump (22) is controlled (25) depending on the amount value stored. With the exhaustion of the drum (17a) assigned to the medium to be dosed proportional to the amount of running water, signals are produced after a drum exchange, which are activated by the assigned dosing pump (22), which respectively carries out a test stroke at intervals. An alarm signal is activated with empty drum. ADVANTAGE - System is improved by simple and cost effective means, so that operation is made easier, yet high accuracy is attained.

Patent DE-4206753-A1 (DE)
Inventor: HORNUNG FRIEDRICH DIPL ING
IPC: B23Q17/10
Filed: 1992-03-04
Abstract: An eccentric disc grinder (1) has a housing (3) in which a motor (11) rotates a grinding disc (45) by means of a driven shaft (31) on a circular path and at the same time around its axis (49). The driven shaft (31) is rigidly coupled in rotation to an eccentric carrier (35) that carries an eccentric pin (37) rigidly coupled in rotation to the griding disc (45) and rotatively mounted, in particular in a rolling bearing (39), with a determined bearing friction and with a determined eccentricity "e" with respect to the driven shaft (31). The grinding disc (45) moves in circles around the axis (32) of the driven shaft (31) with eccentricity "e" and at the same time, because of the bearing friction, rotates around its own axis (49) or that of the eccentric pin (37). In order to prevent the grinding disc (45) from accelerating up to the speed of rotation of the driven shaft, the speed of rotation of the grinding disc (45) is modified depending on the perpendicular force that acts on its working surface (47), in that a motor speed regulator automatically sets a higher speed of rotation when the perpendicular force is increased and a lower speed of rotation when the perpendicular force is reduced.

Inventor: SCHLOEGEL ANTON
IPC: C09D11/50
Filed: 1992-05-06
Abstract: The invention concerns a marking agent to produce markings which will remain visible at high temperatures, in particular those encountered in welding. The marking agent includes at least one luminescent phosphor of the Lenard or Reinstoff type suitable for use at a temperature of at least 500  DEG C and which, when exposed to the radiation emitted by a high-temperature source, radiates a clearly visible emission in the 400-800 nm wavelegth region.
