Title: Injection engine fuel or fuel constituent
IPC: C10L1/18
Filed: 1947-05-01
Abstract: A Diesel-fuel constituent of unstated composition is prepared by passing air or other oxygen-containing gas through a predominantly non-aromatic petroleum distillate free from asphaltic and resinous materials at a temperature of 200-400 DEG  F. and then treating the product with a strongly acid reagent such as sulphuric, hydrochloric, phosphoric, or nitric acid, or dimethyl sulphate, for a period less than 90 minutes at a temperature below 150 DEG  F.  A relatively stable oxygenated product is thereby obtained.  Specification 255,020, [Class 2 (iii)], is referred to.ALSO:<PICT:0657478/III/1> A process of preparing a relatively stable high cetane-number Diesel fuel or component of such fuel comprises contacting partially oxygenated hydrocarbons having an "oxygen factor" of at least 250 as hereinafter defined with a strongly acidic reagent at a temperature below 150 DEG  F. for a period less than 90 minutes. The oxygenated products may be prepared by passing air or other oxygen-carrying gas through a predominantly non-aromatic petroleum distillate relatively free from asphaltic and resinous materials at a temperature of 200-400 DEG  F., preferably from 250 DEG  to 350 DEG  F., in the presence of a small amount of seed stock from the previous run.  The oxygen factor is determined as follows: From 2 to 10 c.c. of oil at 68 DEG  F. are mixed with 20 c.c. of a 40 per cent solution of chloroform in glacial acetic acid, and 2 c.c. of saturated aqueous potassium iodide.  The mixture is shaken, diluted and titrated with 0.1 normal standard sodium thiosulphate. The oxygen factor=112 X titer in c.c's\sSvolume of sample in c.c's (see U.S.A. Specifications 2,317,968 and 2,365,220).  The strongly acidic reagent may be sulphuric, hydrochloric, phosphoric, or nitric acid, or dimethyl sulphate.  Referring to the diagram, the oxidized oil from the oxidizer 4 is rapidly cooled, preferably to a temperature below 95 DEG  F., with water from a pipe 17 and washed with dilute caustic soda in an agitator 18 from which spent aqueous solutions are withdrawn by a pipe 23.  The purified oil is then treated in a vessel 25 first with strong sulphuric acid and then with water, and is then either fed to storage or concentrated in a fractionating column 37. In an alternative process, the oxidized oil is first concentrated, for example at a temperature below 350 DEG  F. and at reduced pressure, to volatilize from 60 to 95 per cent of the oil and produce a residue having an oxygen factor of at least 1000 which is then treated with strong acid as before, which reduces the oxygen factor to about 20 per cent of its original value.  Specification 255,020 [Class 91], also is referred to.

Filed: 1960-04-06
Abstract: 978,333. Doppler pulse radar. ELECTRIC & MUSICAL INDUSTRIES Ltd. April 6, 1961 [April 6, 1960], No. 12274/60. Heading H4D. Relates to a Moving Target Indicator (M.T.I.) pulse radar in which the echo signals are combined with a CW reference oscillation coherent with the transmitted signal and then detected, the resultant signal being applied to a subtracting circuit (1) directly and (2) via a delay line 9 producing a delay of one pulse recurrence period. In such a system the relative phase between an encho signal and the reference oscillation may be such that the amplitude of the output from the detector is so small that it is obscured by noise and according to the present invention this is prevented by (1), Fig. 1, applying the reference oscillation in phase quadrature to two separate combining circuits 7 and 19 to which the echo signals are applied, each combining circuit being coupled to a corresponding detector, delay and subtracting circuit, e.g. 8, 9, 10 and 20, 21, 13, and the outputs from the two subtracting circuits 10 and 13 being combined vectorally in a circuit 11 coupled to the display device 12, or (2), Fig. 2, using a single combining circuit 7, detector 8, delay 9 and subtracting circuit 10 and cyclically varying the phase of the reference oscillation such that its phase varies by at least 90 degrees within the duration of a received echo pulse. As shown, a coherent RF oscillator 4 is phase locked to the transmitter 2 and an IF reference oscillation is derived therefrom by mixing with an output from the receiver local oscillator 14 but alternatively the coherent oscillator may operate at IF or the transmission may be effected by pulsed amplification of a stable oscillation. In Fig. 2 the phase variation is produced by a modulator 25 synchronized with the pulse modulator 1; alternatively the phase modulation may be effected after the reference signal has been reduced to IF.
