Title: Process for refining used oils and conversion of acid-sludge produced therein to asphalt
Inventor: SANTOS BENJAMIN S
IPC: C10C3/04
Filed: 1994-02-21
Granted: 1999-01-05
Abstract: A process for significantly decreasing the acid sludge settling time in waste oil recovery processes comprising the steps of heating used oil to a high temperature above 725 degrees Fahrenheit, cooling the heated oil, adding an oxidizing agent to the oil, allowing the acid sludge to settle within a period of approximately 24 to 72 hours, separating the acid-sludge-free oil from the acid sludge which settles out of solution as a result of addition of the oxidizing agent, and adding a polishing agent and separating the re-refined oil from the spent polishing agent. The spent polishing agent is recycled, and the acid sludge which settles out after oxidation is converted to either hard, oxidized asphalt or soft asphalt or asphalt products such as emulsions etc. The process produces a high quality re-refined oil rapidly and economically with no acid sludge disposal problem.

Abstract: The present invention relates to a method for controlling, in an electrostatic precipitator unit comprising discharge elec-trodes and collecting electrodes between which a varying high voltage is maintained, a pulsating direct current supplied to these electrodes. In the method according to the invention the frequency, pulse charge and/or pulse duration of the pulsating direct current are caused to vary such that a plurality of combinations of frequency, charge and duration are obtained. For each of these combinations; the voltage U between discharge electrodes and collecting electrodes is measured, and for each of these combina-tions; a voltage level U ref is determined, measured or calculated, In a defined time interval, for each of these combinations, either the integral I k = U.(U-U ref),dt is measured and/or calculated during the time interval, or A i = U.(U-U ref) is mea-sured at a number of points of time, whereupon I k or linear combinations of A  i are used to select the combination of fre-quency, charge and duration of the pulsating direct current,

Abstract: The present invention is directed to a semiconductor laser device comprising, as shown in Fig. 1, on a buffer layer 32 of n-GaAs, a clad layer 31, a wave guide layer 30 and a carrier block layer 29 of n-AlGaAs, a side barrier layer 28 of non-doped AlGaAs, an active layer 27 which is formed by two non-doped GaAs quantum well layers and a barrier layer of AlGaAs, a side barrier layer 26 of non-doped  AlGaAs, a carrier block layer 25, a wave guide layer 23 and a clad layer 22 of p-AlGaAs, and a cap layer 21 of p-GaAs in this order. Inside the wave guide layer 23, current narrowing layers 24 having a lower refractive index and higher A1- composition than that of the wave guide layer are formed to sandwich a stripe-shaped active region 34. This creates a refractive index difference between the active region 34 and buried regions 33 in which each of the current narrowing layers 24 exists, thereby forming a refractive index guide structure. Thus, it is possible to obtain a high-output semiconductor laser device of the refractive index guided type which is easy to manufacture.
