Title: Artificial line for use in cross-talk calibration in telephony
IPC: H04B3/40
Filed: 1926-06-04
Abstract: 261,338. Felten & Guilleaume Carlswerk Akt.-Ges. Nov. 12, 1925, [Convention date]. Artificial lines.- In an artificial line for use in measuring cross - talh between two telephone lines, in accordance with principles described in Specification 189,165 and elsewhere, ohmic resistances only are employed, so that the measurements may be independent of frequency. The resistances are arranged to form a T, Fig. 1, or an H, Fig. 2, and a further resistance may be bridged across the left-hand (input) end of the line. The resistances W1, w, are adjusted so as to represent units and tenths, respectively, of the " damping," while the resistance W2 represents the impedance as measured from the right-hand (output) end. The input voltage Va (representing the disturbing transmitter .is related to the output voltage Vc(representing the disturbed receiver) approximately by the formula Va/Ve = W1/w. [1 + (W2 + W)/R] where W<1>, W2, wr are the resistances indicated in Fig. 1, R is the load resistance, and w is small compared with W1. On identifying this formula with one for a real line Va/Ve = ¢ e<b># (1 + Z/R), where Z represents the " wave resistance " and b the .. damping," it is found that Z # W2 and b = loge W1 + loge (2/w), w being neglected in the value of Z. Hence Z and b may be imitated by means of separate adjustments of W1 and W2 respectively. In the case of b, units of damping are represented by W1 and tenths by w.

Title: Process for the production of valuable hydrocarbons by the destructive hydrogenation of carbonaceous materials
IPC: C10G1/06
Filed: 1935-05-15
Abstract: <PICT:0456371/III/1> In the destructive hydrogenation of carbonaceous materials the reaction chamber is heated up to the required temperature by passing therethrough a material previously heated to at least said temperature by indirect contact with hydrogen which is heated up to a high temperature by causing part thereof to interact with oxygen to form water.  The material heated may be a gas, e.g. hydrogen or the carbonaceous materials undergoing the reaction. The hydrogen may be heated by combustion with oxygen in a heat-exchanger or in a small vessel situated between the heat-exchanger and the reaction vessel.  The initial materials may also be heated by flue gases or steam.  Hydrogen is introduced through a line 2 into a vessel 1 where it is partially burnt by oxygen introduced through a line 3.  The hot gases formed pass into a heat-exchanger 5 through which fresh hydrogen is circulated.  The heated hydrogen is passed through a line 6, and in admixture with middle oil supplied through a line 15 flows with or without further heating in a preheater 17, into the reaction chamber 8.  The hydrogen issuing from the converter 8 is mixed with the hot gases issuing from the chamber 1.  The gases leaving the heat-exchanger 5 are cooled to condense vapour and water in a cooler 10, the water and oil are separated in a vessel 11 and the oil is recirculated through a line 18.  The hydrogen is further purified by passage through a cooler 12, stripper 13, and washer 19, and is then returned to the heat-exchanger through a line 14.

Title: Improvements relating to lubricating oil compositions and to the operation of internal combustion engines
IPC: F02B3/06
Filed: 1956-05-08
Abstract: A lubricating oil composition particularly suitable for use in diesel engines run on residual fuels comprises a stable suspension of particles of one or more basic solids in a mobile lubricating oil which has been soap-thickened to an extent sufficient to give it a finite yield value at 15 DEG  C. but insufficient to destroy its mobility, at least some of the particles being of non-colloidal size. The lubricating oil may be a mineral or synthetic oil.  The basic solids are preferably basic compounds of calcium, strontium, barium, magnesium or zinc, e.g. CaCO3, Ca(OH)2, basic magnesium carbonate, Mg(OH)2 or MgO. Preferably the major proportion of the particles have a dimension of less than 1m .  The basic solids preferably comprise 0.5-10% wt. of the composition.  The soaps used are the metal salts of fatty acids.  The compositions may be prepared by first thickening the bulk of the oil with the soap or a soap-based grease, adding a slurry of the basic particles in the remainder of the oil, passing through a homogenizer and deaerating.  In examples 4% wt. of calcium carbonate or hydroxide or 2.3% wt. of magnesium hydroxide is added to an S.A.E. 30 mineral oil thickened with from 1 to 3% wt. of lithium stearate, aluminium stearate or a calcium soap of C16/C18 fatty acid, and in some instances a silicone anti-foam agent is incorporated.

Filed: 1947-05-30
Abstract: 638,425. Pulse delaying circuits. COSSOR RADAR, Ltd., and LEVIN, A. May 30, 1947, No. 14429. [Class 40 (vi)] [Also in Group XXXVIII] Brightness control circuit for a C.R.T. display in a writing telegraph (see Group XXXVIII) provides a delayed switch-on of the spot after the writing stylus touches the tablet and an immediate switch-off when the stylus is removed from the tablet. The writing voltage from the stylus is connected at A to amplifier valves 45 and 46 in cascade feeding through rectifier 47 and a circuit 48 of short time constant to provide positive bias for the grid 49 of the C.R.T. which is normally biassed to "black" level. Valve 45 is negatively biassed so that a certain minimum input (adjustable by potentiometer 59) is required before signals are passed to valve 46, which is biassed to cut-off. The output from 45 is also passed to amplifier valve 54, rectified at 55 and fed through a long timeconstant circuit 56 to provide positive bias for valve 46 whereby the valve 46 becomes operative at a delayed time after the application of the signal at A. The positive bias value is maintained independent of input signal level fluctuations by a limiter 57. A similar limiter 50 is applied to the C.R.T. bias-circuit. The C.R.T. is "blacked out" immediately the writing voltage is removed owing to the short time-constant of circuit 48.
