Title: Dewaxing of oils by dilution chilling - using solvent mixt. contg. methylene chloride
Inventor: WEST THEODORE H
IPC: C10G73/08
Filed: 1978-09-02
Abstract: Dewaxing of petroleum oil stocks (esp. lubricating stocks) is carried out by passing the waxy oil through a multistage chilling zone while injecting a cold dewaxing solvent into at least some of the stages and maintaining a high agitation rate to give substantially instantaneous mixing. The pptd. wax is then sepd. from the oil-solvent mixt. and the oil is recovered from the mixt. The improvement comprises using a solvent consisting of a mixt. of (a) CH2Cl2 and (b) acetone, methylethylketone (MEK) and/or MeOH. The solvent contains >=20 (pref. 20-85) wt.% CH2Cl2. Compared with similar processes using MEK/MIBK or MEK/toluene as solvent, the process has a lower solvent requirement, gives higher dewaxed oil yields and filtration rates, and requires less energy for solvent evapn.

Title: Heating oil burner system - has nozzle protruding through baffle opening into mixing tube and inside air guide surface
Inventor: BUNTE HEINRICH
IPC: F23D11/40
Filed: 1978-10-03
Abstract: The heating oil burner has a disc-type air baffle at the end of the flame tube and a central opening. A spray nozzle is mounted on the baffle, and there is a mixing tube coaxial to and inside the flame tube secured to the downstream side of the baffle. Oil sprayed from the nozzle enters the mixing tube together with air flowing through the baffle, opening, where the ejector effect of the air draws hot gases in the combustion area downstream of the tube in through the gap in the latter to mix with the air. The nozzle (6) protrudes through the baffle opening, so that its outlet is inside the mixing tube (4). It is enclosed by an air guide surface (7) of truncated-cone section and tapering towards the outlet at the opening, so as to form with the latter an annular gap, through which air flows into the mixing tube.

IPC: H04B3/04
Filed: 1979-11-09
Abstract: A signal processing circuit for a signal varying in its properties, e.g., in its degress of distortion, in which the input signal is fed in parallel to two similar processing circuits e.g., equalizers, the characteristic of which can be varied by a control signal, wherein the control signal from the one processing circuit is periodically varied and the output signal is fed to a detector circuit which in optimum signal processing emits a trigger pulse to a holding circuit 52 which stores the corresponding control signal level, which is fed to the second processing circuit. A variable delay unit for the data is controlled by a continuously varying up-down counter, the contents of which continuously vary at the rate of a high frequency clock pulse. The direction of count and the time of the count is controlled by comparing the relative time-positions or phases of a timing pulse received with the data and a timing pulse generated at the receiver.
