Title: Process for producing mixed fertilizers and products thereof
Inventor: SEYMOUR JAMES ELDRED
IPC: C05B1/04
Filed: 1956-03-14
Abstract: <PICT:0829490/III/1> Phosphate fertilizers are made by treating calcium metaphosphate with sulphuric acid in the presence of water, whereby the metaphosphate is hydrolysed to o-phosphate and this is further acidulated, the acid product being then neutralized by adding an ammoniating agent.  The amount of water used is 1 to 5 times the stoichiometric quantity, and the acid/metaphosphate ratio being 0.1 to 1.5 by weight.  In a suitable apparatus, sulphuric acid and calcium metaphosphate ground to 8 mesh, are admitted to the upper tier 1, Fig. 2, of a pug mill, and water is added to form a slurry and mixed by contra-rotating paddles.  The mixture soon hydrolyses and is fed at about 100 DEG  to 300 DEG  F. by a rotary agitator section 8 in a deep bed to a second tier pug mill 2 supplied from below with an ammoniating agent fed through spray pipe 11. Preferably a salt having a negative heat of solution is added at the point of ammoniation to reduce the temperature of the semi-plastic solid, e.g. KCl, NH4NO3, (NH4)SO4.  The neutralized product may be mixed with ammonium sulphate produced in situ, from sulphuric acid, and ammonia supplied to spray pipes 11b, 11a respectively.  The product is then further mixed to form a dry crumbly solid in mill 3. As ammoniating agents, anhydrous ammonia, or solutions of ammonium hydroxide, ammonium nitrate, urea-ammonium hydroxide with or without formaldehyde, or mixtures of these, may be used.

Title: Tipping mechanism for tilting a receptacle or body
IPC: B60P1/20
Filed: 1938-04-08
Abstract: 501,629. Tip-wagons. BURGESS, A. F. (Anthony, W. C.) April 8, 1938, No. 10791. [Classes 103 (iv) and 108 (i)] In an arrangement for tipping a wagon or like body of the kind in which the power is transmitted through a lever fulcrumed on the body and having a pivotal connection with the support, means are incorporated so that the lever, after functioning as a lever for a predetermined displacement of the body, ceases to act as such and subsequently the tipping effort is transmitted directly to the body. In the construction shown a wagon body 1, is pivoted at 12 to the underframe 13 and is actuated by means of an hydraulic cylinder 17 and piston rod 20, which is pivotally connected by a cross shaft 22 to power transmitting levers 33 fulcrumed at each side of the body between pairs of plates 28, 29. The free ends of the levers 33 bear upon rollers 23, 24, which are supported on the underframe and, during the early part of the tipping, serve successively as fulcra for the levers 33. Each of the inner plates 29 is provided with a curved slot 30 along which the shaft 22 moves until, at the time that the levers 33 are losing contact with the rollers 24, it reaches the ends of the slots 30, whereupon the piston rod 20 operates directly upon the body 1. In order to prevent over-tipping locking elements 40, having a general shape similar to that of the levers 33, but having wedge-shaped locking tongues 41, Fig. 6, working in the slots 30, are pivoted on the same spindles 35 as the levers 33. The locking elements move substantially with the levers 33, so that the locking tongues 41 follow behind the cross-shaft 22 to prevent such rearward movement of the latter in the slots 30 as over-tipping would entail. In a modification, the locking devices are constituted by forming a series of ratchet teeth along the lower edges of the slots 30 and fitting the cross-shaft 22 with co-operating pivoted pawls. Specification 475,214 is referred to.

Title: Improvements in the preparation of ammonium diuranate
IPC: C01G43/00
Filed: 1959-04-01
Abstract: Ammonium diuranate having a bulk density not less than 1.4 g./ml. and having a particle size below 3 microns is prepared by precipitating finely divided ammonium diuranate from an aqueous solution containing per gallon, between 0.3 and 0.6 pounds of uranium, 0.15 and 0.3 pounds of fluoride and an excess of at least 0.3 pounds of ammonia over that stoichiometrically required to neutralise any acid present and to form ammonium diuranate.  The ammonium diuranate precipitate is separated from the mother liquor without washing and the fluoride - containing ammonium diuranate is thereafter dried.  It is particularly suitable for converting to uranium dioxide of bulk density of 2.4 g./ml. or more, from which high density compacts having at least 60% theoretical density may be obtained.  Such compacts may be sintered to obtain uranium dioxide bodies of more than 90% theoretical density.  The ammonium diuranate may be formed by hydrolising uranium hexafluoride in an ammonia solution.  For example uranium hexafluoride may be added to a solution of ammonia in the mol ratio of 1 to 4 after which the required excess ammonia is rapidly added in the form of a 27% solution to precipitate the uranium diuranate.  Alternatively ammonium diuranate from any source may be dissolved in a solution containing sufficient ammonium bifluoride to produce a U/F ratio of about 2 and the required excess ammonia rapidly added to precipitate the high density finely divided ammonium diuranate of the invention.  Alternatively ammonium diuranate may be precipitated from a neutral solution of uranyl fluoride and ammonium fluoride by adding the required excess of ammonia thereto.  Specification 850,957 is referred to.

Filed: 1945-05-02
Abstract: 600,512. Cathode ray oscillographs. WEBLEY, R. S. May 2, 1945, No. 11195. [Class 37] [Also in Group XL (c)] A cathode-ray-tube indicator comprises means for deflecting the oscilloscope beam in one direction according to the difference between two applied voltages and in a transverse direction according to their sum, and also means for so varying the deflection sensitivity of the oscilloscope beam that the deflected spot is drawn out into an extended trace. The two voltages are applied to the deflection plates 6, 8 of a cathode-ray tube. The plates 6 and 8 are joined through equal resistances to the plate 9 which is connected to earth through a variable resistor 13. Plate 7 is taken to a variable tapping on the resistor chain 14 so that the spot is deflected towards the bottom of the screen. Consequently, the horizontal deflection is proportional to the difference and the vertical deflection is proportional to the sum of the applied voltages, while the cathode-ray-tube voltages are obtained from an unsmoothed power supply which causes the beam velocity and therefore the deflection. sensitivity to be modulated at the supply frequency. Thus, the deflection of the spot is varied so that a straight line trace 18 is obtained, its length being a measure of the mean voltage applied and its inclination being a measure of the ratio of the difference voltage to the mean.
