Title: Transistor switching circuit
IPC: H03K5/01
Filed: 1962-05-03
Abstract: 979,964. Transistor switching circuits. RADIO CORPORATION OF AMERICA. May 3, 1962 [May 19, 1961], No. 17089/62. Heading H3T. In a transistor switching circuit having an inductive load, e.g. magnetic memory elements Lc, in the collector circuit of a switching transistor T 1 , a further inductor Le is provided in the emitters circuit to prevent saturation of the transistor and collector current overshoot when the transistor is initially rendered conducting. As described, the steady current through the NPN transistor T 1  when conducting is determined by a potential Va which is normally prevented from being applied to the base by diode 24. When PNP transistor T 2  is rendered conducting by a negative pulse on its base diode 24 conducts, and the base of transistor T 1  is clamped to Va volts to render it conductive. In order to limit the current rise time the value of the inductor Le is at least as large relative to Lc as Va is to the applied collector potential Vcc.

Title: Purification of hydrocarbon oils
IPC: C10G17/02
Filed: 1934-06-08
Abstract: <PICT:0439250/III/1> Hydrocarbons are purified and freed from sulphur compounds by treating the oil with an acid in a series of stages, subjecting the mixture of acid and oil to centrifugal separation after each stage and finally treating the purified oil with doctor solution, wherein the oil in at least one stage is treated with acid which has already been used in a stage through which the oil is subsequently treated.  Lubricating oil or a motor fuel distillate is fed by a pump 14 into a contacting chamber 4 together with caustic soda fed under compressed air from a tank 1 through a meter 21.  The mixture is discharged into a settling tank 9, from which the oil flows through a cooler 51 to the first of three acid contactors 5, 6 and 7.  Sulphuric acid is forced by compressed air from a tank 3 and a meter 23 to the contactor 7 where it is mixed with oil which has passed through the stages 5 and 6.  The resulting mixture passes to a centrifuge 13 from which purified oil is discharged through a pipe 59, and acid through a pipe 60 to the contactor 6.  The mixture from this contactor is separated in a centrifuge 12 from which acid passes to the first contactor 5, and the oil passes through a cooler 65 to the succeeding contactor 7.  The oil and acid flow in countercurrent in the first two stages and in the same direction in the last stage. Two acid tanks 2, 3 are provided tank 3 containing more concentrated sulphuric and is used in the last stage, while the less concentrated acid in tank 2 may be admitted to the contactor 6. The purified hydrocarbons discharged from the last centrifuge 13 pass into a contactor 8 supplied with caustic soda from tank 1 and a meter 24. The resulting mixture passes to a settling tank 10, from which the oil passes to a stage in which it is treated with doctor solution (sodium plumbite).
