Abstract: In the 2 stage process at 750 degrees C - 850 degrees C and 1200 degrees - 1280 degrees C a mixture of NaCl and Na2SO4 are roasted with ore or the concentrate. Na2SO4 can be replaced by Iron or Ammonium-sulphate and the latter can be regained by washing the flue gases, resulting in ammoniumchloride which can be used later to ppte. V from soln. In the 3 stage process at 500 degrees - 700 degrees C, 750 degrees - 850 degrees C and 1200 degrees - 1280 degrees C Iron and Ammonium sulphate are used or a sulphide or sulphate e.g. Iron pyrite or elementary sulphur. At 450 degrees C the equilibrium conditions are such that a maximal amount of trioxide results the Vanadiumpentoxide and Ferric oxide act as catalytic accelerators. In every process the V ore or concentrate are first fine-crushed and ground and salt and concentrate or V ore are carefully mixed. Roasting is under oxidising condns.
Patent FR-2133665-A1 (FR)
IPC: G01B7/00
Filed: 1972-04-13
Abstract: 1392503 Measuring dimensions electrically M POSSATI [trading as APPARECCHI ELETTRONICI MARPOSS] 14 April 1972 [14 April 1971] 17470/72 Heading G1N An electronic battery fed measuring instrument such as a dimension gauge includes an element which is moved by a workpiece when it is placed in the measuring position to permit the battery to feed the instrument, the battery being in open circuit in the absence of the workpiece. The feeler gauge of the instrument is connected to a ferromagnetic element 20 coupling transformer 14 forming part of a transistor 11 oscillator. In the absence of a workpiece element 20 is in the lower position so that the inductance in the collector circuit of the transistor 11 is such that the oscillator does not oscillate and due to the high resistor 12 the battery discharge current is very small. When the workpiece is in the measuring position the element 20 moves upwards by an amount proportional to the dimension of the workpiece and the oscillator commences to oscillate. Positive feedback from the output of detector 18 causes the oscillations to be intensified and stabilized to an amplitude determined by the position of element 20. Meter 19 indicates the amplitude of the rectified oscillations and hence dimension of the workpiece. Removal of the workpiece causes the oscillations to cease and the battery 13 to be connected in substantially open circuit again.

Title: Fabrication of ceramic resistors - involves flame spraying ferrite powder onto ceramic substrate followed by impregnation
IPC: H05B3/14
Filed: 1973-07-12
Abstract: Fabrication method is for electrical resistors designed to be submitted to severe thermal cyclic loading. A flame torch is used to spray a powder onto an insulating surface (30) to form a porous covering (31) and this covering is then impregnated with a dielectric material so as to fill the pores and thus avoid short circuits when high voltages are applied. The porosity of the covering reduces the density of the covering to at least 93% of the theoretical density. The powder utilised is a ceramic ferrite powder. The ceramic substrate may be a rectangular tile shaped block, and the ferrite powder may be sprayed onto one side of it. Metal terminal surfaces may be applied to the ends of the strip of ferrite powder.

Title: Rotary fitting for extreme fluid pressures - has pressurised sealing faces between stationary and moving components
IPC: F16L27/08
Filed: 1974-01-25
Abstract: A rotary hydraulic fitting for very high pressures has a cylindrical body. The fitting inlet is screwed into the body on one end. A flange nut clamps a tapered seal ring into a matching location on the inlet body. A second seal taper is held similarly at the rear end of a piston. The neighbouring outlet tube is held in suitable roller bearings. When the the pressure fluid is applied, the two end faces of the sealing tapers which are in contact with one another, form a seal under the reaction force of the piston. The outlet tube can thus be rotated without leakage between moving and stationary components.

Title: Loaded vehicle stability device - has detector for lateral tilt of vehicle preventing tipping mechanism operating
IPC: B60P1/04
Filed: 1974-02-06
Abstract: The device prevents operation of tilting devices capable of overturning the vehicle, whenever lateral stability is uncertain. It consists of a position detector, a transmitter and also a control mechanism. The detector measures the transverse inclination of the vehicle, if this exceeds a given value, the transmitter passes the information to the control mechanism to lock the tilting device. One example is a detector (1) fitted to a tilting bin (8) on a vehicle axle (7). If the angle (ALPHA) exceeds the given one, the bin cannot be tilted. The control mechanism can be electric or pneumatic and the tilting mechanism mechanical.
