Abstract: 630,954. Variable attenuation networks. TELEPHONE MANUFACTURING CO., Ltd., and HARRISON, K. W. Jan. 15, 1945, No. 1198. [Class 40 (iv)] [Also in Group XL (b)] In a variable attenuator network for use in telegraph circuits or echo suppressors in which the polarity of a controlling voltage determines the conductivity or non-conductivity of rectifiers in the series and shunt paths, both the series and the shunt rectifiers, are shunted by suitable resistances to make the terminal impedance of the network constant irrespective of the closed or open condition of the network. If the point M2 is made negative with respect to M1, the network has low attenuation by virtue of the conducting state of the series rectifiers ZL1 ... 4, and the non-conducting state of the shunt rectifier bridge ZS1 ... 4. With control voltage of opposite polarity the series rectifiers are non-conducting and the shunt rectifiers conducting and the network has high attenuation. In the open state the input terminals are virtually through-connected to, and closed by, the output impedance. In the closed state the input impedance comprises two resistances R in series with the conducting shunt bridge and the values of R are adjusted to give the desired terminal impedance. In a modification, Fig. 2 (not shown), the series path comprises resistances bridged by rectifier groups.

Title: Process for the production of aluminium salts of the higher aliphatic or cycloaliphatic acids
Inventor: WILSON ERNEST
IPC: C07F5/06
Filed: 1949-01-19
Abstract: A continuous process for the production of an aluminium soap in a coarsely granular readily filterable form from a fatty acid or monocarboxylic cycloaliphatic acid having at least 7 carbon atoms in the molecule comprises mixing with vigorous agitation at an elevated temperature an aqueous solution of an alkali soap of the fatty or cycloaliphatic acid and an excess of an aluminium salt in aqueous solution corresponding to a value between 11 and 13 per cent (calculated as Al2O3) over the theoretical requirement, the alkali soap solution being employed at a higher temperature than that required in the reaction mixture and the aluminium salt solution being employed at a lower temperature, the relative proportions in which the respective solutions are added being controlled to maintain the said required temperature in the reaction mixture.  It is stated that the theoretical requirement of the aluminium salt is calculated on the assumption that the aluminium soaps contain two carboxyl groups per aluminium atom in the molecule.  The reaction temperature is that usual for the preparation of aluminium soaps, viz. about 65 DEG  C.  It is preferred to add the aluminium salt solution in two stages, so as to maintain a faintly acid condition in the first stage and this is done by splitting the feed of the soluble aluminium salt solution and feeding one stream to the first reaction stage at a closely controlled temperature of between 90 DEG  and 95 DEG  C., for example, together with the alkali soap solution at a temperature between 90 DEG  and 95 DEG  C., for example, the proportioning being controlled so a to maintain the required pH value in said first stage.  The reaction mixture then passes to the second stage wherein a second stream of the soluble aluminium salt solution is continuously added so as to yield the required aluminium soap.  In an example for the production of aluminium laurate, four stainless steel vessels are arranged in series with overflow connections and sodium laurate solution from a tank maintained at 93 DEG  C. and aluminium sulphate solution from a tank maintained at 31 DEG  C. are fed to the first vessel so as to maintain the reaction temperature at 67 DEG  C. and the pH at 6.0-6.1.  The overflow from the first vessel is mixed in the second vessel at 67 DEG  C. with a further supply of the aluminium sulphate solution so as to increase the excess of aluminium salt calculated as Al2O3 to between 11 and 13 per cent, the feed of the aluminium sulphate solution being adjusted so as to maintain the temperature in this vessel at 57 DEG  C.  The overflow is then discharged in cascade into the second and fourth vessels, maintained at 57 DEG  and 56 DEG  C., respectively.  A fixed adjustment of the pH to neutrality is then carried out in a separate vessel after removal of about two thirds of the mother liquor and the resulting slurry is then filtered, washed and dried at below 100 DEG  C.

Abstract: 822,905. Voltage measuring bridges. STAHLWERKE BOCHUM A.G. Jan. 18, 1956, No. 1643/56. Class 37. In a device for measuring the effective and reactive components of a low-frequency alternating voltage U 2  with respect to a voltage U 1  of similar frequency, the former is connected over switch 29 to the diagonals of a bridge comprising adjacent resistors 16, 17 and adjacent vibratory contact rectifiers antiphasedly excited by series operating coils S 1  and S 2  energized from the output of transformer 27, whose primary is push-pull energized by pentodes IIIa, IIIb, excited from switch Sch alternatively connecting over contacts 11, 12 to the output of pentode I or to the 90 degrees lagging phase-shifted output of pentode II energized from I over phase-shift network 22, 24. Harmonics are eliminated by fundamental tuned circuit Z in the anode of pentode I, whose input is excited from voltage U 1 , which is initially selected by switch 29 to energize the rectifier bridge. Switch Sch is set to select the output of II, and circuit Z is tuned for zero reading of instrument V in the remaining bridge diagonal. Returning switch 29 to select U 2 , the instrument indicates the reactive component thereof, and the effective component thereof when switch Sch selects the output of I. Closure of switch 18 to shunt operating coil S 1  with capacitance 19 and series resistance 20 shifts the phase of operation of rectifier G 1  by 60 degrees with respect to the other, whereby the resultant contact closure timing of the rectifier bridge is two periods of 120 degrees per excitation cycle, so that the third harmonic error is eliminated from the measured result.

Abstract: 157,942. Waltz, E., and Meusser, H. Dec. 22, 1919, [Convention date]. Void [Published under Sect. 91 of the Act]. Condensers.-In a device for recording or reproducing motion successions, applicable for sound-succession or picture reliefs, the sound or relief is caused to actuate a movable electrode or electrodes of a condenser of substantially constant capacity charged by a source of direct or alternating current, whereby variable capacities are produced in parts of the condenser resulting in variations of potential between these parts and suitably chosen points, which variations are used to govern one or more vacuum intensifiers connected directly or indirectly with the circuit of a receiver, which may be a telephone, an engraving tool or stylus, or a wireless antenna. Fig. 8 shows a constant capacity condenser with stationary electrodes a', a<2> of alternate polarity and movable electrodes b<1>, b<2> alternating with one another and electrically connected in two series simultaneously movable by a combination of levers such as the " Nourenberg scissors " so that when the electrodes b<1> are displaced to positions of higher potential the electrodes b<2> are displaced to positions of lower potential and vice versa, and potential variations are thus produced between the fixed and movable electrodes and also between the movable electrodes proportional to the displacement, and each of these may govern a vacuum intensifier. In a condenser arrangement for transforming diaphragm movements into variable potential differences, the stationary electrodes are spaced apart by distance rings in a casing with a screw-on top carrying a mouthpiece and clamping a diaphragm from which the movable electrodes are supported by a central spindle terminating below in an armature above an electromagnet. Fig. 11 shows a constant capacity condenser c<1> supplied by a high frequency undamped source q and with one set of connected movable electrodes governing, by the potential variations between these and a point x of a potentiometer p, the grid circuit g of an intensifier r.

Abstract: 1494552 Control of printers SPERRY RAND CORP 15 Jan 1975 [16 Jan 1974] 1658/75 Heading G4H The typecarrier of a printer contains coded identifying marks which are read and compared with the code corresponding to a desired type carrier. As described, an on-the-fly printer uses interchangeable type bands 38 containing sync. marks 44 and marks 436 ... 43a adjacent the first ten characters on each band; the first and tenth marks are always "1" and the other eight provide an identifying binary code. The code marks are sensed 41 (magnetically or optically) and entered in a register 63 with the aid of the sync marks; a gate 64 receives the first and tenth bits when the band is in its initial position and causes the code to be entered in register 65. The contents of register 65 and of a register 67 containing the code of the desired band (transmitted from a CPU or a tape unit) are compared 66 to produce a signal 66a which, in the event of a mismatch, inhibits printing and sends an "intervention status bit" to the CPU or causes a lamp on a console to be lit. A description (Figs. 1, 2, 4, 6, not shown) is also provided of a conventional printer which is slightly modified for the purposes of the invention.
