Patent GB-1048134-A (GB)
Title: Fertilizer
Inventor: BROWN GEOFFREY GEORGE
IPC: C05B1/02
Filed: 1963-05-15
Abstract: Concentrated fertilizers containing ammonium phosphate are prepared by reacting together 2.0 to 2.5 moles of calcium phosphate, 6 to 30 moles of ammonium nitrate, 2 to 6 moles of ammonia and less than 3 moles of H2SO4 to form a melt having a pH 2.5 to 5.5 (measured by dissolving 1 part of melt in 9 parts water) at a temperature of 130 DEG  C. to b.p. of the melt and cooling the melt. Ca(H2PO4)2, NH4NO3, H2SO4\t and NH3 may be added to a previously prepared melt which may be at its b.p. and comprise NH4NO3, NH4H2PO4, CaSO4, CaHPO4 and water; CaHPO4 being at 0 to 100% by weight based on the CaSO4 and 2 to 7% water may be present. A gas which is inert to the reaction (e.g. air) may be passed through the melt.  The Ca(H2PO4)2 may be in the form of single or tripl superphosphate or a mixture of these and it may be used as a slurry formed by reacting phosphate rock with H2SO4 and/or H3PO4 in the presence of part or all the NH4NO3 used in the process. NH4NO3 may be added as an 85-95% aqueous solution at 80-130 DEG  C.  The H2SO4 may be > 95% by weight and added so that the amount of sulphate ion present is at least sufficient to react with all the Ca derived from Ca(H2PO4)2.  In order to increase the proportion of water-soluble P2O5 above that available from triple superphosphate, H3PO4 and an equivalent amount of NH3 may be included in the mixture. The product melt may contain 40 to 85% by weight NH4NO3 and the N: P2O5 ratio of the melt may lie between 3: 1 to 1: 2. In the examples the process may be carried out in one or more reaction vessels. The product is disintegrated after cooling to give non-caking granules.

A yarn guide spaced from a rotating package and having a constant amplitude of traverse, has its traverse speed varied such that the take up point on the package lays to a variable extent with respect to the yarn delivery point on the yarn guide. The resulting winding has a variable traverse length and is stated to reduce or eliminate end build up on the package. The rate of reciprocation of the yarn guide may be varied continuously, intermittently or spasmodically. The variation may be of the same magnitude or of different magnitude at each occurrence of the variation. In Fig. 1 a steel band 2 passes over end pulleys 3, 4. Along its upper span the band 2 carries a plurality of yarn guides 1 for traversing yarn onto a plurality of packages 13. On its lower span the steel band carries a follower 7 engaging a slot 9 on the periphery of a cylindrical cam 10 to cause the band 2 to oscillate. The cam 10 is driven by an electric motor 18 via a variable speed gear box 17. Alternatively the motor 18 may be of variable speed by any known means, such as variable resistances, on oscillator controlled build-up and let down circuit, or cam controlled switching circuit having different resistive values.

Abstract: 478,511. Thermionic valve circuits. FAUDELL, C. L. July 17, 1936, No. 19814. [Class 40 (v)] A valve circuit for generating saw - tooth voltages consists of an oscillator which controls a second valve ; equal potentials of opposite phase being generated across a circuit element or elements associated with both valves. Valve 1 acts as a blocking oscillator, condenser 5 and resistance 6 controlling the frequency of the saw-tooth voltages produced across condenser 2 which charges through resistance 3 and discharges during oscillation of the valve. Synchronizing signals are applied at terminal 7. The grid of the second valve 10 is coupled to the first by transformer windings 4, 8, 9, and the time constant of the combination 11, 12 is made greater than that of resistance 6 and condenser 5. The second valve charges condenser 14, normally discharging slowly through resistance 13, at the same time that condenser 2 is discharged. Terminals 15, 16 are connected to the deflecting plates of a cathode-ray tube. In modifications, resistances 3, 13 may be replaced by chokes, a single condenser connected between the upper ends of resistances 3, 13 may be used, and also the anode of valve 10 may be connected directly to the anode of valve 1. The invention is not restricted to blocking oscillators and other types of oscillator may be employed. Specifications 235,254, [Class 37], and 402,629 are referred to.
