Abstract: 466,953. Automatic exchange systems. AUTOMATIC ELECTRIC CO., Ltd. Oct. 7, 1935, No. 12981 /37. Convention date, Nov. 7, 1934. Divided out of 463,874. Drawings to Specification. [Class 40 (iv)] In an automatic telephone system; all the supervisory signals comprise alternating current of a single voice-frequency modulated by an alternating current having a frequency, the same for all signals, which is below the voice frequency range, the switch setting impulses being transmitted as interruptions of the voicefrequency current. For the purposes of the invention, the lower limit of the voice-frequency range is taken at 200 cycles, and modulation is regarded as the production of a complex wave with sum and difference frequencies as distinguished from mere superimposition of one frequency on a basic frequency or mere interruption thereof. The systems described comprise two arrangements identical with two of the arrangements described in Specification 463,874.

Abstract: 495,194. Self-tapping screws. CLAYTON, C. E. EVERY-. (Illinois Tool Works) May 7, 1937, No. 13144. [Class 89 (i)] [Also in Group XXII] A self-tapping screw comprising a threaded holding portion A, Fig. 1, and a hardened threaded tapping portion B, is provided with threads on the tapping portion decreasing in thread diameter towards the entering end, the core diameter of this portion increasing in the same direction. The axial pitch of the thread is uniform throughout the screw but the exposed core portions 16, Fig. 1, increase in axial width towards the entering end of the screw, as shown more clearly in Fig. 2, where the reverse tapering characteristics of the screw are indicated by dot-and-dash lines.

Abstract: 662,835. Supplying liquid fuel. BENDIX AVIATION CORPORATION. May 1, 1946 [May 7, 1945]. No. 13205/46. Classes 7(iii) and 7(vi) A fuel supply system comprise: a centrifugal pump 48 provid. ing a pressure head C at a meter. ing orifice 56 which varies in response to engine speed, and a valve 68, controlled by a diaphragm 38 subject to the pressure B downstream of the metering orifice and a pressure A intermediate the pressure C and the fuel inlet pressure D, maintains the pressure drop across the orifice 56 proportional to the square of the engine speed. The pressure A is controlled by regulating the fuel flow through a byepass 86 containing an orifice 88, controlled by a needle 92 actuated by a capsule 98 subject to the air charging pressure, and a fixed orifice 42 so that the pressure at A acting on the diaphragm 38 is intermediate between pressure C and D. As the springs 76,. 78 are light, the valve 69 maintains the pressure at B substantially equal to A and hence the pressure drop across orifice 56 is maintained proportional to the square of engine speed and modified by valve 92 in accordance with the air charging pressure. The valve 69 is adjusted by screw 82 to be slightly open when the engine is inoperatiye to provide an idling enrichment. The fuel is emulsified by air supplied to a conduit 63a in the nozzle 66 by a pipe 64 facing the flow of intake air, which may be supercharged. Correction of the fuel flow for variations in exhaust back-pressure and intake air and exhaust gas temperatures may be obtained as described in Specification 662,837.

IPC: C04B7/60
Abstract: 134,920. Mond, A., (International Precipitation Co.). Nov. 13, 1918. Potassium salts.-Potassium chloride is recovered in the production of Portland cement by adding sodium chloride or an alkaline-earth (including magnesium) chloride to the mix, or to the powdered fuel, or to both, and conducting the burning in the usual manner so as to obtain a clinkered, but not fused, product. The cement mixture may contain shale and limestone, with or without a material, such as feldspar, to increase the potassium content, and may be dry or wet ground. The fume may be separated by electric separation, for instance as described in Specification 109,105. The leaching of the fume is preferably effected with hot water or mother-liquor, say at 50-100‹ C. The leaching is not complete, the residue being returned to the next cement change. The solution is evaporated to complete dryness or to crystallize potassium chloride, in which case the mother-liquor may be returned to the next wet-ground cement charge.
