Abstract: 1493928 Lubricating oils SHELL INTERNATIONALE RESEARCH MATTSCHAPPIJ BV 16 Dec 1974 [18 Dec 1973] 54257/74 Heading C5E High viscosity index lubricating oils are produced by catalytically cracking a heavy hydrocarbon feed comprising one or more foots oils (i.e. the components remaining after higher melting point waxes have been separated from slack wax) in the presence of hydrogen. The foots oil can be obtained from brightstock slack wax which has been obtained by deasphalting, extracting with furfural and then dewaxing by either sweating the slack wax or dissolving the wax in solvent and cooling to crystallize higher melting point waxes to leave a foots oil-solvent mixture. The feed treated can also comprise a waxy lube oil vacuum distillate, slack wax from waxy lube oil vacuum distillate, brightstock waxy raffinate or from lube oil fractions obtained by hydrocracking a deasphalted oil. The hydrocracking can be carried out at 325-450‹ C. and 10-250 bar; in examples, catalysts comprising (A) 37 parts by weight nickel, 70 parts tungsten, 14 parts fluorine and 100 parts alumina and (B) 10 parts nickel, 20 parts molybdenum, 2 parts phosphorus, 2À5 parts fluorine and 100 parts alumina are used after sulphiding with a hydrogen/hydrogen sulphide mixture. The hydrocracked oil can be hydrofinished, distilled and then dewaxed with the separated wax being recycled to the hydrocracking.

Title: Circuit arrangement for indicating the operating condition of series-connected capacitor units

Filed: 1972-12-15
Abstract: 1411609 Protective arrangements SIEMENS AG 15 Dec 1972 [18 Dec 1971] 58202/72 Heading H2K A protective arrangement for a plurality of series connected capacitor units C1 ... C6 comprises a circuit arrangement which produces an output dependent on the difference between a voltage proportional to the potential difference across one unit and a voltage proportional to the sum of the potential differences across the units. As shown, voltage transformers W1 ... W6 have their primary windings connected across respective units C1 ... C6 each of which comprises a plurality of parallel capacitor elements each in series with a cut-out. The secondary windings of the transformers W1 ... W6 are connected to the primary windings of auxiliary transformers Tr1 ... Tr6 each of which has four secondary windings, e.g. S11 ... S14. The first set of secondary windings S11, S21, S31, S41, S51, S61 are connected in series with each other and with one of the windings, e.g. S12, of the second set to a rectifier G11 in a comparator circuit. Similarly the third set of auxiliary current transformer windings are connected in series with each other and with one of the windings of the fourth set to the other rectifier G12 of the comparator circuit. Normally each of the windings of the second and fourth set of primary windings produce the same voltage and the sum of the voltages in the first set is lower than that voltage, but the sum of the voltages in the third set is higher. However the difference voltages applied to the rectifiers G11, G12 are normally the same. Should the capacitor unit C1 have a defective element, the resulting increase in the voltage across that unit, causes the voltage at the rectifier G11 to increase while that the rectifier G12 decreases, the device M being energized to provide a signal. A further comparator arrangement is provided for each of the other capacitor units C2 ... C6. In an alternative arrangement, each auxiliary transformer has only two secondary windings, one set being connected in series to the rectifier G11 and the selected other secondary winding being connected to the rectifier G12.

Abstract: 1336573 Fluidic switching circuits JOHNSON SERVICE CO 8 Dec 1970 [8 Dec 1969] 58326/70 Heading F1P A differential fluidic switch comprises a first fluidic comparator 4, a second fluidic comparator 5, and a fluidic set-reset flip-flop unit having two switching outputs, the first comparator 4 having a signal input 21, a high reference level input 23, and a high level output 29, the second comparator 5 having a signal input 23', a low reference level input 21', and a low level output 30', each of the comparators being such as, in operation, to  produce an output signal having either one of two different values and thereby indicating whether the level of a signal at its input is higher than or lower than the level of a reference at its reference level input. When the signal at input 1 reaches a selected high-pressure, the fluidic comparator 4 creates a switching signal which establishes a stable on condition at the output line 3 so long as the input signal pressure remains above a selected low-pressure determined by the setting of the fluidic comparator 5. If the pressure should drop below the selected low-pressure, the fluidic comparator 5 establishes a switching signal giving a resultant stable off condition at output line 3. The stable off condition is maintained as long as the pressure does not rise to the selected highpressure at which the fluidic comparator 4 operates to establish the stable on condition at the output line 3.

Abstract: 1386070 Keyboards R BENNISON 9 March 1972 [10 Dec 1970] 58573/70 Heading G4H [Also in Division B6]  A pressure actuated signalling device includes a wave transmission device and means operable in response to the arrival at one or more sensors of a wave transmitted through the device to provide a signal indicative of or dependent upon the region of the device from which the wave was transmitted. The waves may be pressure shock waves generated by tapping fixed keys or depressing spring-loaded keys on a keyboard; or they may be high-frequency waves coupled to the device by a key. The transmission device may be a rod R 1 , R 2  having piezoelectric transducers A, B at each end and configured as shown so that a generated wave will be received by A and then by B; A starts a clock pulse generator G, Fig. 4 (not shown) which is stopped by B, the resulting pulses being counted by a binary counter (C) and fed to a read-out device (O) or a read-only memory (code converter), the final output thus being dependent on the difference in the times of reception of the wave at A and B. The device may alternatively be a rectangular plate having transducers at its edges. In an alternative embodiment, a shock wave is set up in a transparent panel forming the outer surface of a display screen by tapping it at a desired point; this wave is detected as above to produce an alteration in the display at the desired or at some other point.
