Patent DE-4101184-A1 (DE)
Inventor: SOBINGER DIETRICH E
IPC: B08B9/093
Filed: 1991-01-17
Abstract: This relates to a method and installation for cleaning floating-roof tanks (1), remaining crude oil (31) first being sucked out and then being pumped into the residue with stirring up the residue (32). After the remaining crude oil has been used up in the course of liquefying the residue, fresh crude oil is pumped through cleaning pipe branches (4) - which may support the floating roof - to stir up and liquefy the remaining residue, until all the residue has been liquefied and pumped out of the floating-roof tank (1). In the course of the tank cleaning, the cleaning supports (4) replace the roof supports (2) otherwise present and are distinguished, on the one hand, by a slender construction which is stable in terms of strength, and, on the other hand, ensure the required stirring-up of crude oil and residue for the liquefaction of the latter. <IMAGE>

Title: Identifying bar=code using inductive sensor - sensing bar=code pattern using part of resonator combined with oscillator to form part of FM demodulating circuit
Inventor: HANKE ANDREAS
IPC: G06K7/08
Filed: 1992-03-12
