Title: An improved manufacture of pour point depressants
IPC: C10G73/04
Filed: 1938-12-21
Abstract: 509,550. Pour-point depressant for oils; ketonic condensation products. STANDARD OIL DEVELOPMENT CO. Sept. 21, 1938, No. 27531. Convention date, Dec. 3, 1937. [Class 91] [Also in Group IV] A wax-modifying agent or pour-point depressant is prepared by condensing a halogensaturated aliphatic hydrocarbon or olefin with an aromatic hydrocarbon, and recondensing the product with an acyl halide. The condensations may be carried out in the presence of a catalyst. The acyl halide may be a derivative of a mono-or dibasic saturated aliphatic acid or of an aromatic or hydroaromatic acid. Thus, 100 parts by weight of chlorparaffin (12 per cent. of chlorine) is condensed with 15 parts by weight of naphthalene using 2¢ parts by weight of aluminium chloride as catalyst at 88‹F. and in 87¢ parts of kerosine as solvent. After 4¢ hours, the catalyst is hydrolyzed by adding isopropyl alcohol and aqueous caustic soda and removed. The product is distilled and condensed with acetyl chloride using tetrachlorethane as the solvent medium. By using different amounts of acetyl chloride and differing amounts of aluminium chloride, products with a differing effect on the pour points of oils are obtained. Other tests were carried out with the product obtained by condensing the first condensate with chloroacetyl chloride.

Filed: 1964-07-03
Abstract: 1,095,148. Transistor relay circuits. GENERAL ELECTRIC CO. Ltd. and A. D. BERRY. June 25, 1965 [July 3, 1964], No. 27551/64. Heading H3T. A fail-safe circuit for energizing a relay 11 when an input voltage 17 is within predetermined limits comprises two pairs of emittercoupled transistors connected as shown to form two comparators. If the input to the base of 1 is below the lower limit transistor 1 is off, 2 and 3 are conducting and 4 is cut off so that the relay is not energized. When the input rises above the lower limit set by the junction of resistors 15 and 16, transistor 1 conducts, cutting off 2 and 3 and allowing 4 to conduct, thus energizing the relay. Above the upper limit set by the junction of resistors 13 and 14, transistor 3 conducts once more and cuts off 4 to de-energize the relay. The current drain is small if transistors 1 and 3 are bottomed when conducting, by suitable choice of resistors 9, 10.

Filed: 1972-06-15
Abstract: 1401045 Read only memory; code converter SIEMENS AG 15 June 1972 [16 June 1971] 27954/72 Headings G4A and G4H In a read-only memory comprising a number of interrogation lines A1-Ax to which read pulses are fed by the selective actuation of switches T1-Tx, and a number of transformer cores K1-K12 each having a secondary winding S1-S12 connected to a respective read amplifier L1-L12, each interrogation line is inductively coupled to certain of the secondary windings by means of primary windings P in accordance with the stored data and each core K is provided with a blocking winding B11- B44, selected ones of which are energized during a read operation to enable read out to be obtained from only selected ones of the read amplifiers. As described a read-out pulse is fed to one of the interrogation lines A1-Ax by closing the appropriate transistor switch T1-Tx. Assuming line A1 is pulsed secondaries S1, S3 and S12 will produce a pulse due to their inductive couplings with line A1 by primary windings P10, P30, and P120. In the absence of the blocking windings a twelve-bit readout would be obtained from amplifiers L1-L12. The use of the blocking windings enables more than one word to be stored for each interrogation line. As illustrated two distinct words are provided by amplifiers L1-L3 and L9-L12 respectively. By selectively energizing one of the switches Tb 1  and Tb 4  the sets of blocking windings B11- B13 and B41-B44 are energized. The blocking windings are arranged to produce an equal and opposite effect to the primary windings so that read out from, say amplifiers L1-L3 is blocked. In the example core K2 does not have a primary associated with interrogation line A1 so that amplifier L2 will receive a read out pulse due to the action of blocking winding B12. However the amplifiers are arranged to respond only to pulses of the polarity induced by the primaries so the opposite polarity pulse due to B12 is not sensed. In an alternative embodiment only one blocking line B1 is provided. The blocking line is connected in series with the parallel group of switches T1-TX so that a read pulse also serves as a blocking pulse. The blocking line is inductively coupled to all the cores K by blocking windings. Selected groups of blocking windings are shunted by transistors so that by energizing one of these transistors the appropriate group of blocking windings is not energized and read out is obtained from the associated group of read amplifiers. Each group of blocking windings is connected in series with a diode poled to pass the blocking pulse but to block a pulse induced in the blocking winding by an interrogation pulse acting through the primaries. Word selection is performed using certain address bits, the remaining address bits being used in a conventional way to select an interrogation line.
