Abstract: 528,653. Separation of paraffin wax from asphalt. NAAMLOOZE VENNOOTSCHAP DE BATAAFSCHE PETROLEUM MAATSCHAPPIJ. May 11, 1939, No. 14108. Convention date, May 18, 1938. [Class 91] Asphalt separated from the products obtained in the straight run distillation of mineral oil is freed from paraffin wax to a considerable extent and completely freed from the presence of any large molecular aggregates of paraffin wax with the aid of hydrocarbons containing one to five carbon atoms by first heating the said products above the temperature at which disruption of dissolved molecular paraffin wax aggregates occurs and then cooling below that temperature and deasphalting within about an hour after the cooling below the critical disruption temperature with the aid of the above hydrocarbons, at a temperature above that at which the paraffin wax begins to separate out. The products are generally heated to from 70‹-120‹C., but preferably not above 200‹C., and the cooling is effected to temperatures of 40‹-120‹C. The critical disruption temperature depends on the presence or absence of solvents, and on the nature of such solvents. Examples are given of experiments to determine the critical disruption temperature and of the application of the process of the present invention to a Mid-Continent residue. In an analogous manner to the above process for obtaining a paraffin wax free asphalt, there may also be obtained a wax free asphalt-containing fuel oil. Such oils have a very low pour point. The term asphalt includes asphalt or its components such as albino-asphalt.

Abstract: 1378985 Arcing preventing in switches SIEMENS AG 22 Nov 1972 [22 Nov 1971] 54095/72 Heading H1N An arrangement for initiating the opening of a main switch a predetermined time before a current zero, comprises means for defining a first time interval tx from a point in time at which the rate of change of the current is zero to an instant in time when the sum of a first quantity u 1  proportional to the current and a second quantity u 2  proportional to the rate of change of the current is zero, and pulse producing means supplying a tripping pulse after a second interval #t xv  beginning at the said instant and being a function of the first interval. As shown, the quantities u 1 , u 2  are applied to amplifiers A, B to produce square-wave signals U R2 , U R1  which are summed to provide a square-wave voltage U R3  converted at C for application to an integrating amplifier D. This amplifier provides a measuring voltage u 3  which increases substantially linearly during the first interval tx and decreases at an increased rate during the second interval. When the voltage u 3  has decreased below a reference value u 4 , a threshold circuit E produces a voltage u 5  which is applied to a pulse shaper F and an amplifier G to produce the tripping pulse u 8  to cause tripping if a control switch I is closed. Should the current through the main switch, or either of the signals U R1 , U R2 , be too low to obtain satisfactory synchronous operation or to provide an adequate tripping pulse, then a circuit H provides a signal u 7  to the amplifier G to cause tripping. In an alternative arrangement a counter circuit may count the oscillations of an oscillator which oscillates at a first frequency during the first interval. During the second interval the counter counts back the oscillations of the oscillator which now oscillates at a higher frequency. When the count is reduced below a predetermined value the tripping pulse is obtained.
