Title: Improvements in or relating to the extraction of titanium compounds from minerals containing the same
IPC: C22B34/12
Filed: 1956-04-25
Abstract: Titanium minerals are treated to convert titanium values to a readily extractable form by mixing the finely-divided mineral with a double fluoride of iron and either an alkali metal or ammonia, and with sodium carbonate, the mixture being thereafter subjected to an elevated temperature for time sufficient to ensure reaction between the titanium compound and the double fluoride, thereby converting the titanium values to a soluble double fluoride of titanium and the alkali metal or ammonium which can be extracted with sulphuric acid. The double fluoride preferably constitutes at least half the weight of the mineral treated.  According to an example, powdered quartz-free ilmenite was mixed with half its weight of potassium ferric fluoride and one quarter of its weight of anhydrous sodium carbonate.  The mixture was roasted in a furnace for two to three hours at a temperature of about 100 DEG  C. and the reaction product was thereafter crushed and extracted with sulphuric acid at 80 DEG  C.

Title: Improvements in or relating to methods of bonding metals to organic fluro-carbon plastic materials and articles made thereby
IPC: H05K3/38
Filed: 1957-04-18
Abstract: 844,776. Laminates. INTERNATIONAL RESISTANCE CO. April 18, 1957 [April 18, 1956], No. 12770/57. Drawings to Specification. Class 140. A metal having a copper surface is bonded to a layer of fluorocarbon plastic containing substantial amounts of polytrifluorochloroethylene, by oxidizing the copper surface to provide layers of cuprous and cupric oxide, applying the layer of plastic thereto and applying heat and pressure to the assembly. The oxidation is preferably effected by a chemical agent such as a hot aqueous solution of an alkaline chlorite. A laminate may be formed by feeding a strip of copper through an oxidizing bath, followed by a washing bath, bringing strips of polytrifluorochloroethylene against the opposite faces of the oxidized copper strip and feeding the assembly between rollers where heat and pressure are applied. Applications described include the production of laminates for making printed circuits, of sealed terminal assemblies which may be moulded to capacitor or resistor casings, and multi-wire flexible insulated cables.

Title: Improvements in and relating to temperature measuring devices
Inventor: GRATTON CHARLES PETER
IPC: G01K3/10
Filed: 1956-04-26
Abstract: 835,551. Temperature-sensitive devices. ENGLISH ELECTRIC CO. Ltd. April 25, 1957 [April 26, 1956], No. 12803/56. Class 40 (1). A device for giving an electrical output which is indicative of rate of change of temperature comprises two temperature - sensitive resistors R1 and R2 with different time rates of response incorporated in a bridge circuit with fixed resistors R3 and R4. The thermometers are so matched that at any constant value of temperature the bridge output is zero. The time rate of response of R2 may be increased by surroundng the resistor by a layer of thermally insulating material. The resistances of R1 and R2 are small compared with the resistances R3 and R4. This reduces the sensitivity but increases the linearity of the response. The output is developed across resistor RL.
