Patent GB-413636-A (GB)
Title: Processes for the production of fertilisers
IPC: C05B1/06
Filed: 1933-01-12
Abstract: Fertilizers are produced by treating superphosphates with concentrated gas liquor in the presence of sulphuric acid in a free state or partly free and partly combined with ammonia of the gas liquor, the proportions of sulphuric acid and of the gas liquor being such that the end product consists substantially of a mixture of calcium superphosphate and neutral ammonium sulphate. The gas liquor is preferably free from cyanogen compounds which are liable to impart an undesirable colouration in the product. The process may be carried out by reacting phosphate rock with sulphuric acid in excess of the quantity required for the production of calcium superphosphate and neutralizing the excess sulphuric acid, before it is able to react with the mono-calcium phosphate formed, with concentrated gas liquor. Alternatively the excess sulphuric acid may be neutralized with an ammoniated solution of ammonium sulphate obtained from concentrated gas liquor and sulphuric acid; methods of obtaining such solutions are described.ALSO:Fertilizers are produced by treating superphosphates with concentrated gas liquor in the presence of sulphuric acid in a free state or partly free and partly combined with ammonia of the gas liquor, the proportions of sulphuric acid and of the gas liquor being such that the end product consists substantially of a mixture of calcium superphosphate and neutral ammonium sulphate.

The output terminals of board 18 are connected through a switch 71 to a second terminal board 45 of a transformer 93, from which board power may be led directly to a socket 104 for operating shop machinery, and may be applied to the primary windings 95 ... 100 of the transformer to give various single and polyphase voltages at the terminals 47, the terminals 81 ... 92, to which the primary windings are brought out, being suitably interconnected, according to the dynamotor voltage, by a change-over plate such as 46, Fig. 17, similar in construction to the dynamotor change-over plate. Corresponding change-over plates for the transformer and dynamotor are coloured alike to avoid confusion with plates appropriate to different voltages. When the machine shop is located near a power supply, such power may be fed into the socket 104 with the appropriate voltage changeover plates in position, the dynamotor being driven as a motor in this case and providing welding current from the welding generator.

Title: Nuclear fuel elements
IPC: G21C3/10
Filed: 1972-01-10
Abstract: 1367712 Fuel elements BABCOCK & WILCOX CO 10 Jan 1972 [8 Jan 1971] 1210/72 Heading G6C A pressurized nuclear fuel rod is formed by first encapsulating the fuel in a casing to form a fuel rod which is then inserted into a pressure chamber, and the chamber after being sealed is evacuated. While maintaining the vacuum in the chamber, the fuel rod is punctured with a fine hole by means of a laser beam. The air inside the fuel rod is drawn out and the chamber is then filled with an inert gas under pressure, the gas being forced into the fuel rod through the fine hole. When the pressure inside the fuel rod reaches equilibrium with the chamber, the hole is sealed by means of a laser beam. For quality control purposes, the chamber is again evacuated and if a leak is present in the seal it will become evident from an increase in pressure being indicated on the vacuum gauge of the chamber.

Title: Method of sealing the envelope of an electron discharge device and electron discharge devices formed by said method
IPC: H01J5/24
Filed: 1963-01-11
Abstract: <PICT:1030703/C1/1> A seal between the two components 11, 12 of an electron discharge device is formed by grinding the mating surfaces so that they contact over a substantial area and then diverge to form a recess 17a into which molten indium - containing solder is forced and allowed to solidify. A sleeve 13, of thin non-magnetic material such as brass, and of such a diameter that it will pass over the end of the component 11 only when heated, is used to confine the solder and may be tinned on the inside to increase the tin content of the solder.  In order to cause the solder to fill the recess completely, the melting takes place while a vacuum is formed in the envelope.  A strip of thin platinum connected to a member within the envelope may be led between the mating surfaces into contact with the sleeve to serve as an electric contact.  The invention can be used for sealing together components of glass or for the forming of glass-to-metal seals.

Abstract: 825,005. Photo-electric position determination. RANK CINTEL Ltd. Jan. 16, 1957 [Jan. 16, 1956], No. 1482/56. Class 40 (3). [Also in Group XL (c)] Apparatus for determining the distance of the flight path of a projectile from the centre of a target space defined by conical surfaces 2, 3 originating at the centre and extending to a narrow spherical zone 4 comprises a photoelectric device 1 receiving light from the zone 4 through a circumferential slot 6 in an enclosure 5, this light being directed on to a photo-electric cell 11 by a convex mirror 7, a lens 8 and an annular slit 10 in a partition 9 defining the target space. Thus passage of a projectile along a flight path such as A or B produces a signal which is fed to a device 22 through an amplifier 12. A further signal is derived from an acousto-electrical transducer 13 which responds to the shock wave of the projectile, this signal also being fed to the device 22 through an amplifier 14. Considering the flight path A the shock wave traverses path 20 and arrives at 13 at a point in time after generation of a signal in 1 corresponding to the time taken for the projectile to travel from 18 to 19. This time interval is directly proportional to the distance dA or dB of the projectile from the target and the device 22 indicates this distance. A delay circuit 15 compensates for the time taken for the projectile to travel between 13 and 1. A device 21 enables corrections to be made for the ambient temperature and the relative velocities of the target and projectile.
