Title: Circuit for generating reset signal
Inventor: EBERLEIN MATTHIAS
IPC: H03K3/356
Filed: 1997-03-03
Abstract: The circuit has a pulse generator (IG) at whose output the reset voltage appears when an upper supply voltage is applied. The pulse generator input is connected to the output of a voltage breakdown detector (DTR) contg. a threshold voltage detector (LDlow) with its input connected to an operating voltage store (US) with two oppositely connected series circuits of a capacitor and diode (C1,D1; C2,D2) between the upper and lower supply voltages forming first and second voltage tappings (A1,A2).  A transistor (NTRANS1) driven by the second voltage tapping lies between a third tapping (A3) and the lower operating voltage. The threshold detector and operating voltage store dimensions are selected so that if the upper voltage falls to a level defined by the detector's threshold voltage the second diode and the transistor block and cause the pulse generator to trigger.

Patent DE-19749530-A1 (DE)
Title: Separating biological waste from sand in basin
Inventor: RUPP MICHAEL
IPC: B03B11/00
Filed: 1997-11-08
Abstract: Collected refuse is discharged into a collecting basin (7) containing fluid, and the heavy fractions sink. The heaviest fraction is dredged and removed as sludge. The lightest fractions are skimmed from the surface and removed for treatment.  A portion of the residual fraction containing concentrated biological residue is drawn from the basin and sieved. The partly dried residue is crushed and fermented and/or composted. In the treatment of biological residue collected as refuse, the biological refuse is received together with impurities such as heavy metals, sand, stones, metal, glass, gravel, and lighter fractions such as pieces of foil, paper and plastic. The collected refuse is first discharged into a collecting basin (7) also containing fluid and in which the heavy fractions sink to the bottom while lighter fractions float. The collected refuse is thus subdivided into three fractions. The heaviest fraction is dredged and removed as sludge. The lightest fractions are skimmed from the surface and removed for treatment. A portion of the residual fraction containing the concentrated biological residue is drawn from the basin and sieved. The partly dried residue is then crushed and subjected to fermentation and/or composting.

IPC: H02M3/07
Filed: 1997-12-06
Abstract: The invention relates to a capacitor supply unit, comprising a charging capacitor for charging up another capacitor (storage capacitor) for operating an electrical consumer, a rectifier (4, 5) which is located between the charging capacitor (2) and the storage capacitor (3), and a switching element (6, 12) which is located between the charging capacitor (2) and the storage capacitor (3) in circuit terms. Said switching element (6, 12) has a control input (7) to which the output of a switching time determining element (9) is applied. The switching time determining element (9) is subjected to a reference voltage Uprot which is small in comparison with the alternate current supply voltage U SIMILAR , and determines the instant at which the switching element (6, 12) switches from a switch position in which the storage capacitor (3) is charged to a switch position in which the charging process is interrupted, according to the voltage Us being applied to the charging capacitor (2) at the output end. The output of a charge status determining element (10) for determining the charge status of the storage capacitor (3) is also applied to said control input (7). Interconnected to represent a logical AND operation, the interconnecting switching time determining element (9) and the charge status determining element (10) act upon the control input of the switching element (6, 12) in such a way that both switching operations of the switching element (6, 12) - switching the capacitor supply unit (1) into charging mode or switching the same to interrupt the charging process - take place at a time when the voltage Us being applied to the charging capacitor (2) at the output end is less than or equal to the reference voltage Uprot.
