Title: Testing nuclear fuel rods
IPC: G21C3/10
Filed: 1977-09-19
Abstract: In order to detect defective fuel rods in fuel elements of water cooled nuclear reactors, the fuel elements are firstly subjected to a hydrostatic alternating pressure treatment. The cladding tubes of the fuel rods are then heated in the vicinity of an accessible end cap, resulting in heating of the water situated in said end cap in the event of damage. The presence of water is established by measuring the temporal temperature characteristic at the end cap or by applying ultrasonic pulses to the end cap and evaluating the echo pulses.

Abstract: 1,162,152. Programmed control of machines CEA-PEREGO S.p.A. Sept.1, 1966 [July 13, 1966J, No.39101/66. Heading G3N. An electronic system for simultaneously controlling two or more machines comprise a single data processing unit for deriving positional control information for the machines in single digital-analog converter for positional data from the machines and a group of positioning servomechanisms for each machine. As shown, tapes, or perforated cards for controlling two machines are read by readers L1, L2 and the derived position signals translated into binary coded information by a decoder D and stored in a memory M to be subsequently fed to a data processing unit EL which uses this information to control two groups of servomechanisms S1 S2 for the machines. Each group of servomechanisms is connected to a group of position detectors R1, R2 which are connected to an analog-digital converter that transforms the positions determined by the detectors into numerical symbols which are transmitted to the data processing unit and to indicators 1N1, 1N2 on which appear numerically the relative positions of the members in the coordinates of the machines. The system is fed from a single power supply unit AL. For simultaneous control of two machines a single reader analyzes a tape or card and reads the programme only when the machines have executed previous commands. Further, the automatic parallel control of two machines can be interrupted and one machine used automatically and the other machine manually. The manually-controlled machine then using the analog-digital converter for the numerical indication of the position of machine members in the co-ordinate axes.

Title: Improvements relating to scrap briquetting presses
IPC: B30B9/32
Filed: 1958-12-10
Abstract: 836,550. Scrap briquetting processes. LINDEMANN, W. Dec. 10, 1958 [Feb. 8, 1958], No. 39859/58. Class 87(2). A scrap briquetting press has a press chamber 1 with a hinged lid 6, the free end of which moves past a wall 10 extending from the chamber, there being a clearance 12 between the end of the lid and the wall when the lid is closed. The surface of the wall 10 is curved in relation to the arc of movement of the free end of the lid so that the clearance 11, when the lid is half open, is less than the clearance 12, thus reducing the danger of scrap getting jammed between the end of the lid and the wall. For the same purpose, ridges 13, 14 are formed in the lid and wall, of various profiles as described in the Specification. Modifications are described in which the wall 10 may be swung away from the end of the lid, to free pieces of scrap, by an eccentric fitting in a slot in the wall and rotated by a hand lever or by a hydraulic ram ; by releasing a bolt which locks the wall to the press frame ; by releasing a screw threaded stop ; or by raising the wall, which has guide slots, by screw jacks or hydraulic rams or a crane. In another modification, Fig. 12, a knife 28 is mounted at the top of the wall and, when rocked by an eccentric 31 rotated by a lever 32, swings back to release jammed scrap. In another modification the knife is advanced by turning a screw threaded shaft. In yet another modification, scrap jammed between a side wall and the lid is freed by swinging the wall outwards by the action of an eccentric. In a further modification, Fig. 15, the clearance between the lid 6 and one of the side walls, e.g. 36, is increased by loosening a nut 42 on the end of the pivot shaft of the lid and then, by tightening screws 43, retracting a bush 39 (which normally projects inwards by the amount of clearance between the lid 6 and the wall 45) and thus allowing the lid to be moved so that the clearance between it and the wall 36 is doubled : by retracting the other bush 40 the clearance the other side may be doubled.

Title: Process for the production of pigmentary tio
Inventor: STREET ERIC
IPC: C01G23/053
Filed: 1965-09-22
Abstract: Iron containing titaniferous material is digested in H2SO4 and lixiviated to form a first aqueous soln. containing titanium sulphate which is hydrolysed to ppt. TiO2.  The hydrous TiO2 obtained is redigested with conc. H2SO4 at elevated temperature and superatmospheric pressure in such a manner that a viscous liquid is obtained which is mixed with water or a dilute acid to form a second titanium sulphate soln.; the latter may then be hydrolysed to ppt. hydrous TiO2 which may be recovered and calcined. The first titanium sulphate soln. may have a concentration of titanium (estimated as TiO2) from 80 to 250 gm./l.; it may be hydrolysed by adding the titanium sulphate to a volume of hot water and the mixture heated to its boiling point.  Before addition the titanium sulphate may be at 50-70 DEG  C. and the water to which it is added at 90-95 DEG  C. The titanium sulphate soln. may be added to water in a ratio of 0.5 to 1 volume of the former to 1 to 3 volumes of the latter.  The hydrous TiO2 from the hydrolysis of the first titanium sulphate soln. may be mixed with sufficient H2SO4 before digestion to give a mixture containing 23-29% by weight TiO2 and an acid/Ti ratio between 1.5 and 2.2.  The second digestion may be carried out at 150-180 DEG  C. and 10 to 50 p.s.i.g. The pressure may be reduced before mixing the viscous digestion liquid with water or dilute acid to form the second titanium sulphate solution.  In order to avoid hydrolysis the viscous digestion liquor may be run into an aqueous titanium sulphate solution containing between 100 and 150 g./l. of titanium (estimated as TiO2) and which has an acid/titanium ratio of 1.5 to 2.2.
