Filed: 1927-01-21
Abstract: 264,867. Stockholms Superfosfat Fabriks Aktiebolag. Jan. 23, 1926, [Convention date]. Manures. - A mixture of monocalcium phosphate and calcium sulphate obtained by decomposing a raw phosphate with sulphuric acid is suspended in water and treated with ammonium carbonate, or ammonia and carbonic acid, at about 40‹ C. for a maximum of 6 hours, whereby di-calcium phosphate and calcium carbonate, or tricalcium phosphate, or a mixture of these phosphates with calcium carbonate, is formed and precipitated, whilst the ammonium sulphate formed simultaneously is wholly or partially recovered, as by evaporating the solution thereof obtained by filtering off the precipitates. The latter are soluble in citrate or citric acid solutions and form valuable manures. Alternatively the monocalcium phosphate in the original mixture may first be converted into di-calcium phosphate by treatment with milk of lime or powdered limestone, and the resulting mixture be treated with ammonium carbonate &c. to convert the calcium sulphate to carbonate and obtain ammonium sulphate. A saturated solution of ammonium sulphate may be used as a carrier for the ammonium carbonate &c., in which case the mixture resulting from the reaction must finally be heated to about 80‹ C. to dissolve the ammonium sulphate formed in the reaction if it is desired completely to remove the latter by filtration. By omitting the heating step or by regulating the temperature after the reaction, more or less ammonium sulphate remains with the precipitate, which may be dried and marketed as a manure. Low-grade raw materials, and those containing a high percentage of iron, alumina, or carbonates, may advantageously be treated by the above process.

Jan. 20, 1931, No. 1883. Convention date, Feb. 10, 1930. [Classes 120 (ii) and 120 (iii).] In yarn-winding machines, particularly drum winders, means are provided to prevent the rotation of the yarn receiver, for example a cop tube, on the winding-spindle in a reverse direction from the normal. As shown, a cop tube X is provided with notches n which are adapted to be engaged by the usual latch 12 for holding the tube in place. During winding, the pressure between the tube and driving- drum 2 tends to slide the tube in the direction of its larger end, but, when the winding-spindle is raised as shown in Fig. 2 to interrupt the driving contact, the tube slides on the spindle and the latch 12 engages one of the notches n, whereby any contrary rotation caused by entanglement of the yarn with a moving part of the machine is prevented.

Abstract: 1,109,703. Power factor improvement. MOSKOVSKY ENERGETICHESKY INSTITUT. 17 Jan., 1966, No. 2031/66. Heading H2H. [Also in Division G3] In a capacitor bank used for power factor improvement and controlled by reverse parallel connected thyristors, current surges due to delayed angular firing of the thyristors are avoided by injecting into the capacitor a current pulse to produce a voltage greater than the supply voltage at that instant to extinguish the thyristor over the middle part of the cycle. Thyristor 1 is conductive from the beginning of a cycle until a voltage U2 is reached when the thyristor is extinguished by a pulse from a circuit 3. The capacitor voltage remains at this value until the thyristor 4 reconducts when the supply voltage U1 is again equal to U2 in the later part of the cycle. As the thyristors conduct when the supply voltage is approximately equal to the capacitor voltage large current surges are avoided. An automatic control circuit is described in the Specification, for producing timed pulses for two capacitor banks connected to a supply through star/star and star/zig-zag connected transformers respectively. Correction of individual phases is provided for.

Abstract: 641,640. Sound transmitting and receiving devices. STEVENS, A. H. (Submarine Signal Co.). Feb. 7, 1944, No. 2272. [Class 40 (iv)] A subaqueous signalling device for transmitting or receiving waves of the order of 10,000 cycles per second employs one or more magneto-strictive driving rods or tubes, and each rod or tube is terminated at one end only in a radiating or receiving element of substantial mass which with the rod or tube forms a resonant system one or more halfwaves long, and the system is arranged so that a node exists in the rod or tube at or very close to the junction of said rod or tube with the radiating or receiving element, the end of the tube or rod not attached to the radiating or receiving element being free of imposed restraint and being without mass load. The combined unit may be supported near the node or the line of the nodes, and the transmitting member may be located in the throat of an exponential horn or be rigidly connected to a solid member of exponential form. As shown in Fig. 1, a tubular magneto-strictive element 13 has a solid end 12 closely fitting the throat of the horn 3 secured to the skin 1 of a ship or vessel. The vibrator has a welded or sweated ring 17 fixed to the horn 3 and a casing 14 is attached with a water-tight gasket 15<SP>1</SP>. Vibration-damping rings 21, 21<SP>1</SP> are mounted on the sides of the ring 17 to shield the element 13 from vibrations transmitted through the walls of the horn. The coils 20 may be fed with direct current to magnetize the element 13 ; alternatively the casing 14 is of cobalt steel and a core 22 extends into the hollow element 13. The leads to the coils 20 are taken through a stuffing box 23. The large end of the horn 5 may be closed by a diaphragm or by a halfwave length plate, Fig. 2 (not shown). In a modification, Fig. 4, magneto-strictive rods 35 are provided with weighted portions 34 rigidly connected to solid exponential horns 32 mounted on a plate 31 secured to the wall 1 of the ship. The energizing coils 20 are supported on a member 51 which may be hollow. A further modification, Fig. 5 (not shown), omits the weighted portions 34. In the arrangement shown in Fig. 6, tubular magnetostrictive elements 40 are sweated into a plate 41 normally of surface dimensions large relative to the wave length of the vibrations to be transmitted. The tube 40 with the associated part of the plate 41 is of length ¢# and the system is supported at approximately the nodal line O-O by a flange 51 secured to the wall 2 of the ship. Groups of the vibrating elements may be fed with alternating current of different phase to produce a directional effect.
