Title: Devices for use in determining distribution of neutron flux
IPC: G21C17/12
Filed: 1970-09-15
Abstract: 1285688 Reactors SIEMENS AG 15 Sept 1970 [16 Sept 1969] 44097/70 Heading G6C The neutron flux distribution inside a nuclear reactor is determined by a collection of neutron detectors, the connecting cables to which do not enter the reactor core and are therefore not exposed to neutron and gamma radiation which would otherwise set up disturbing currents within the cables. The flux measuring system, 2, extends over the active zone, 1, of the reactor and comprises the individual detectors 3 to 9, the upper ends of which, together with leads 11, lie outside the reactor. The longitudinal distribution of neutron flux in the reactor core is determined by measurement of the current differences between adjacent detectors. The detectors are formed of cobalt which emits electrons when subjected to a neutron flux.

Title: Improvements in or relating to the production of non caking common salt
Inventor: SAUNDERS JAMES
IPC: C01D3/26
Filed: 1959-12-31
Abstract: The caking tendency of cubic crystalline Na Cl is reduced by adding to it one or more compex iron compounds, wherein the iron is bonded through one or more oxygen atoms with a saturated aliphatic compound having 3 to 6 C atoms and containing two or more COOH groups together with one or more OH groups; tartaric, citric, gluconic acids are specified.  The complexes may contain other anions in the molecule to render it neutral, for example alkali metal or ammonium ions. Preferred are ferric ammonium citrate, gluconate or tartrate.  The amount used is greater than ,0002% by weight on dry Na Cl and depends on the particle size; thus for 0,3 mm. cubes the preferred range is ,0001-,002%. In order to obtain a free flowing product other customary salt additives, e.g. Mg CO3 may also be added.  The complex iron salt may be added to the Na Cl by either spraying a solution of the additive on to damp or dry salt separated from its mother liquor, or by the introduction of the additive into the mother liquor containing the solid Na Cl prior to separation.  The two examples refer to spraying dry salt with ammonium ferric citrate. The Provisional Specification also refers to the following classes of anticaking additives. M5[V (CN)5 NO] M3[Cr (CN)5 NO] M4[Mo(CN)5(OH)2NO] M6[Co(CN)5]2 where M is an alkali metal (including ammonium) ion of which K5[V(CN)5 NO.H2O] is the subject of an example.

Abstract: 1,014,369. finishing fabrics; textile treating apparatus. K. A. MULLERS. Nov. 2,1964 [Nov. 7, 1963], No. 44603/64. Headings D1L and D1S. A woven, knitted or non-woven fabric is continuously napped in at least two napping passes through a napping machine and is moistened to an increasing degree from one napping passage to the next. The first napping pass may be carried out with the fabric in a dry condition to allow the clothing points to penetrate more powerfully into the fabric and subsequent napping passes are carried out with an increasing degree of moisture. As shown, on the feed side of a napping machine 10 a moistening device 12 which may be in the form of a steamer is mounted on a bracket 11. As the seam 14 of the endless fabric 15 to be napped passes a seam feeler 13, the latter, through a lead 17, regulates a control 16 of the device 12 and thus also the supply of steam by the steamer. After a predetermined number of passes of the fabric is, the feeler 13 switches the supply of steam off. In modifications, the moistening device is controlled by a pass counting mechanism and may be heated by elements heated by electricity or gas.

Abstract: 1457193 Jointless track circuits WESTERN INDUSTRIES (Pty) Ltd 28 Oct 1974 [11 June 1974] 46555/74 Heading B7N In an arrangement for detecting the presence of a rail vehicle axle in a points or crossing track section an A.C. signal from source 1 is applied to the points or crossing junction and receivers 8 receive signals from across the rails in each approach track and provide an output to AND circuit 13. The signal is applied via transformer 2 having its secondary connected in series with capacitor 3 and the inductance of the rails between the junction and the intersection B to form a tuned circuit at the signal frequency. The extremities of the approach tracks are defined by series tuned circuits 4 comprising capacitors 5 and inductors 6 connected across the rails and the receiver inputs are connected across further capacitors 9 disposed across the rails between the extremities of the tracks and the junction and which resonate with the inductance of the rails DE and FG between the capacitor and the extremity defining tuned circuits 4. This last arrangement can be modified by selecting a slightly higher value of capacitor 9 so that the presence of a vehicle first brings the circuit to resonance and then causes a quicker drop away in the voltage across the capacitor.
