Abstract: <PICT:0582357/III/1> In the production of anhydrous magnesium chloride, a pulverous material comprising at least 20 per cent. of magnesia (of a kind capable of self-setting rapidly at room temperatures when mixed with water) is fed to a moving surface where an aqueous medium is supplied thereto in such quantity that the material forms with the assistance, if desired, of a coating of light powder of reaction materials, into spheroidal pieces which are not wet enough to adhere to one another, the pieces without substantial change in shape being subjected to chlorination at elevated temperatures in the presence of a reducing agent after or without a period of standing with or without warming and with or without baking or kilning.  As shown in the drawing, a mixture of carbon and finely milled magnesia is fed by a screw conveyer 14 into one end of a rotary cylinder 15 coaxially disposed within and fixed to a tapered drum 18.  The drum is mounted on a platform 23 pivotally supported at one end 16 and mounted at the other end on a jack 32. The cylinder 15 accommodates a sieve 27 through which very fine material passes and is returned to the conveyer by means of a lift 33.  Water is fed into the drum by two perforated pipes 28, 29 extending parallel to each other along the full length of the drum.  The spheroidal pieces, ranging from 1/16 in. to 1 1/2 in. in diameter escape through an annular end wall 41 and gravitate through a chute 43 into a receptacle 44 from which they are fed to a chlorination furnace.  The reducing agent in a finely divided form is preferably incorporated with the magnesia before adding the water which may contain magnesium chloride, p  sodium and potassium chlorides or other soluble salts, or if desired the reducing agent in gaseous form, e.g., carbon monoxide, may be fed separately into the chlorinator.  The reaction materials may include carbon, peat, sawdust, sodium and potassium chlorides, magnesium carbonate, magnesium oxychloride, non-setting-magnesia and solid magnesium chloride hydrates. Specifications 259,498, 333,741, [both in Class 1 (iii)], and 548,800 are referred to.

Abstract: 1,010,468. Converting; supply systems for electronic flash apparatus. BRAUN A.G. May 4, 1962 [May 6, 1961], No. 17219/62. Headings H2F and H2H. [Also in Division G3] A D.C. to D.C. converter, e.g. for electronic flash equipment, in which a capacitor 11 is charged over a diode 23 from a D.C. source 10, comprises an oscillator constituted by a transistor 17 and a transformer 20, 16, 9; the arrangement being such that when the capacitor 11 is fully charged a glow lamp 11 strikes and renders a control transistor 8 conductive so . disabling the oscillator, the collector/emitter circuit of transistor 8 being connected to transformer winding 9 which acts in opposition to the feedback winding 16. A series connection of a capacitor 6 and a diode 4 is arranged in parallel with the lamp circuit and assists in disabling the oscillator. As the voltage rises on the capacitor 11 the capacitor 6 charges through the back resistance of diode 4 and through a resistor 3. When the lamp 7 strikes, the voltage across it drops and the capacitor 6 discharges over diode 4 to produce a current impulse in the lamp circuit which helps to bias transistor 8 to conduction. A fall in the voltage on capacitor 11 extinguishes the lamp 7, whereby the oscillator again becomes operative by virtue of the voltage applied to the base of transistor 17 by way of the feedback winding 16 and a voltage divider 12, 13 associated with the source 10.

Abstract: 914,056. Control of D.C. motors. GENERAL ELECTRIC CO. May 25, 1959 [May 23, 1958], No. 17730/59. Class 38 (3). [Also in Groups XXVI, XXVII and XXXV] As shown, an electric motor 21 is supplied from a generator 20 whose output voltage P 0  is not inherently in direct proportion to the excitation voltage S 2  supplied to its field winding 22, the arrangement being such that the voltage P 0  is made to be a linear function of the signal voltage S 1  applied to a field winding 25 of an exciter-amplifier 24 which is selected to have a fixed linear relation between its output voltage S 2  and its input voltage S 1 . For this purpose, the effect of the winding 25 is modified by a field winding 26 supplied with a control voltage S 4  which is a fraction of the difference between the voltage S 2  and a voltage S 0 . The latter is a fraction of the voltage P 0  and is derived from a voltage divider 28. The voltage S 4  is attenuated by the relative number of turns in the windings 25, 26, or by a voltage divider. The differential voltage (S 2 - S 0 ) may be adjusted by a variable resistor 29. Transient variations are prevented by a filter circuit 67, 67a, connected across the field winding 22, and a filter circuit 68, 68a, across the voltage divider 28. In a calendering machine for plastics, heated rollers 41-44, stripper roller 50, and a conveyer 52 are each driven by an electric motor having a separate generator network 60-65 as described. The critical relative speed of each motor is adjusted whilst the machine is operating at minimum speed, after which a master controller 66 is turned to increase the speed signal S 1  to all the generator networks 60-65 simultaneously to multiply the speed of each roller by an equal amount. In this manner, the relative speeds of the various components of the machine are maintained accurately during acceleration to prevent breaking of the plastic sheet. The same arrangement may be applied to other machines, such as machine tools. A similar control system may be used for non-electric prime movers, Figs. 6, 7 (not shown).
