Title: Controllable motor drive for four-quadrant operation
Inventor: TUESCHEN ALFRED
IPC: H02P15/02
Filed: 1989-03-03
Abstract: The invention relates to a controllable electric-motor drive for a four-quadrant operation, especially with a three-phase asynchronous motor. In order, in the case of such a drive, to obtain a characteristic comparable to a hydrostatic drive, a combination of drive components 1-4 is arranged between the drive shaft 5 of the motor M and the drive shaft 6 of the load L, which components can be selected using a control device ST, depending on a control command W and additional variables such as the rotational speed X2 of the load L, the loading X3 of the drive motor M and the direction of rotation X1. The drive shaft 5 of the motor M and the drive shaft 6 of the load L are coupled via an eddy-current coupling 1 having adjustable excitation or via a hydrodynamic coupling having adjustable degree of filling. A clutch 2 is arranged in parallel to the eddy-current coupling 1. As brakes, an eddy-current brake 3 having adjustable excitation or a hydrodynamic brake having adjustable degree of filling and a mechanical brake 4 engage on the drive shaft of the load L. Such a drive allows control of the rotational speed of the load L in all four quadrants at constant motor rotational speed, both synchronous running between the drive shaft 5 of the motor M and the drive shaft 6 of the load L and braking of the load L down to a standstill being possible. <IMAGE>

Patent DE-3936689-A1 (DE)
Title: Liquid jet-producing device
Inventor: SCHMIDT JOERGEN
IPC: B05B9/04
Filed: 1989-11-03
Abstract: Variations in the flow resistance through the jet-producing members (2) influence in a pumping and processing unit (1) such that the liquid is supplied to the jet-producing member (2) under a higher pressure.  When the jet-producing member exhibits high flow resistance, and conversely, an ejector (11) is placed between the pump (9) and the jet-producing member.  The suction inlet (15) of the ejector (11) is connected to the source of liquid (7) through a non-return valve (13). The ejector (11) will aspirate liquid through suction inlet (15) and hence deliver a larger quantity of liquid under low pressure to the jet-producing member, when the latter exhibits a low flow resistance, whilst when the jet-producing means (2) is set to a higher flow resistance.  The ejector (11) will no longer function, as non-return valve is closed, and liquid flows in a smaller quantity, but under a higher pressure through the ejector to the jet-producing member.

Patent DE-4022845-A1 (DE)
Inventor: KRISTEN KLAUS
IPC: F24C15/10
Filed: 1990-07-18
Abstract: Temperature sensors or temperature sensor arrangements made from glass ceramic and bonding film resistors, suitable especially for control and limitation of output in glass ceramic cooking areas, are distinguished in that thin- and/or thick-film resistors are baked on supports of glass ceramic, for example, in the area of the cooking zone of a glass ceramic cooking surface, and one or more glass ceramic resistances are delimited and bonded there, and the film resistors form parallel and/or iterative circuits with the glass ceramic resistances. By suitable selection of the dimensions as well as the surface resistances and temperature coefficients of the bonding film resistors and the type of sensor circuit (parallel and/or iterative circuit), the temperature resistance characteristic of a sensor circuit can be varied within wide limits, e.g., the temperature area of use of a glass ceramic sensor can be considerably expanded toward low temperatures. The geometric shape of a sensor arrangement can be matched to the specified temperature distribution of a surface to be monitored, for example, a glass ceramic cooking surface in the area of the cooking zones, so that practically all areas of the heated surface essential for the temperature control and limitation are detected.
