Abstract: 284,294. Amme-Luther Werke Braunschweig der Miag M³hlenbau und Industrie Akt.-Ges. Jan 27, 1927, [Convention date]. Cements, Portland.-A process for producing a white Portland cement from coloured raw materials, for example from ferruginous materials, consists in adding small quantities of inorganic substances which on heating give colourless melts with the colouring components of the raw materials. Suitable inorganic substances are phosphates and borates alone or combined with metallic halogen compounds such as calcium fluoride or chloride. Reducing agents such as coke mav also be added or the material may be heated in a highly reducing zone. In an example coke, flux, and borax are added to a mixture of ferruginous raw materials and after calcination under reducing conditions the clinkers are first coarsely ground and then finely ground, iron being removed magnetically after each grinding. The process may be applied to the raw materials separately before mixing.

Title: Improvements in process of extracting precious metals, more particularly applicable to the treatment of poor ores or materials
IPC: C22B11/06
Filed: 1936-01-31
Abstract: Materials containing precious metals, particularly poor ores or tailings, are treated with a solution of an oxidizing halogen compound such as a hypochlorite, the pH value of which is adjusted to a value between 6,5 and 5, air under pressure being preferably blown through the solution during the treatment.  The solution obtained, containing precious metals such as gold, platinum, palladium, iridium, and osmium, non-ferrous metals such as copper, cobalt, nickel, and bismuth, and also iron and aluminium, is subjected to the action of a reducing agent such as charcoal to precipitate the precious metals, and then electrolysed to regenerate the hypochlorite &c. and to precipitate the remaining metals other than iron and aluminium which remain in solution.  After adjustment of the pH value if necessary the regenerated solution is used again.  Bromine or iodine compounds may be used for the extraction, which is effected with the ore in a coarsely ground condition, and in the raw or roasted state.  An example relates to the treatment of tailings obtained by floatation of a mispickel ore, which contain mainly iron, arsenic and sulphur, and about 1 grm. of gold per ton.

Title: Improvements in the production of turbine blades
IPC: B24B21/00
Filed: 1952-02-04
Abstract: 736,075. Grinding turbine blades. JAMESON, J. L. Feb. 4, 1953 [Feb. 4, 1952 ; May 14, 1952], Nos. 2954/52 and 12257/52. Class 60. The surface of a turbine blade 2 is finished by registering it with a die 1, disposing between the die and blade an abrasive band 3 having a width which is a fraction only of the length of the blade surface, and moving the blade and the die on the one hand and the band on the other hand relatively to one another in a direction lengthwise of the band and in a direction lengthwise of the blade. The first of these relative movements is effected by driving the band 3 and the second by mounting the blade holder 4 and the die 1 on a support 5 which is moved continuously or intermittently on slide bars 6 by an hydraulic ram and cylinder controlled by valves operated in timed relationship with the feed movement of the blade towards the die. This feed movement and the raising and lowering of the blade holder 4 may be obtained as described in Specification 719,124. The angle of approach and leaving of the abrasive band 3 to and from the die 1 are adjusted to suit the angle of twist at the particular part of the blade being treated by a drag box 14 and a roller 15. The former is carried by a frame 20 mounted on pivoted links 21 and is raised and lowered as the support 5 is moved by a control track in the latter which engages a stylus on the box. To enable the band to run with sufficient slackness over the die, the box is fitted with rollers 16 ... 19 and an adjustable spring 26 which subjects the rollers 16, 18 to a frictional drag. The roller 15 is carried by a bracket 28 pivoted at one end about a vertical pivot so that it can be swung in step with the movement of the support 5. The band 3 is driven by being passed between a driven drum 8 and a belt 9 which passes over pulleys 10, 11, 12 of which one is driven. Alternatively, a reciprocating band may be used. Specification 591,890 also is referred to.

Abstract: An indicator display device comprises a column 10 of electroluminescent (e.l.) segments 12A-12F co-operating with the scale of the indicator, a column 20 of photoconductive (p.c.) elements 24A-24F co-operating with the <PICT:1021901/C4-C5/1> e.l. elements of col. 10, and second control columns 14 and 18 of e.l. and p.c. segments.  In operation, the e.l. element 16G is first lit, light (dashed lines) from this rendering the p.c. elements 22F and 24F conductive, and the light signal thus running up the e.l. columns 10 and 14 until a feedback A.C. signal taken from conductors 62A-62F vice resistors 60A-60F and lead 36 is found, in the null detector 34, to balance the input signal 30 to be displayed. The columns 14 and 18 are then extinguished, while latched columns 10 and 20 remain alive. The sequence is then repeated.  In an alternative (Fig. 3, not shown), the control signal runs up control columns 14 and 18, and is then transferred to the display columns 10, 20 and there held until a biased null detector clears these columns just before balance is reached on the next cycle in the control columns.  In a further alternative, a third set of latched p.c.-e.l. columns are used as the display columns, being activated from the column 10 only at a set time interval.
