Patent ZA-903563-B (ZA)
Title: Production of acid soluble titania
Inventor: HOLLITT MICHAEL JOHN
IPC: C08K/
Filed: 1990-05-10
Abstract: The specification discloses a method of making acid digestible titania. The method comprises the steps of: (1) adding a magnesium or manganese compound to a titaniferous mineral if the content of manganese and magnesium in the mineral is insufficient; (2) heating the mineral in the presence of a reductant for a sufficient length of time and at a sufficiently high temperature to permit the reduction of iron containing compounds to metallic iron and enable titania present to convert to an acid digestible form; (3) cooling the mineral; and (4) separating iron from the mineral by means of an aqueous aeration step. The titaniferous mineral contains insufficient magnesium and manganese if the following expression is not satisfied: 1.98a + 1.14b/d  >/=  0.08 where a represents the percentage by weight of MgO contained in the mineral, (b) represents the percentage by weight fo MnO contained in the mineral; and (d) represents the percentage by weight of TiO2 contained in the mineral. The magnesium or manganese compound is either an oxide or a compound that is capable of converting to an oxide under reaction conditions. An aqueous aeration technique described in the specification involves the use of a sequesterant that is capable of sequestering iron from the mineral without significantly lowering the local pH while at the same time permitting the formation of an oxide of iron at a point away from the mineral. An example of such a sequesterant is citric acid.

Title: Driven traveling mechanism with steerable individual running devices
Inventor: EEUWIJK WILLY VAN
IPC: B61F/
Filed: 1990-08-20
Abstract: The driven running gear is intended for underslung rail vehicles with at least two articulated body units. It has two individual sets of running gear (2, 2') fitted with steering means (15, 15', 16). These are interconnected to pivot about their horizontal axis beneath the centre of the wheel axles (8, 8') by a link (3), which, at its ends, has transverse bearers (4, 4') to support a body unit to which are secured at least one motor (21, 21') and a brake (23, 23', 24, 24') which drive and brake the running gear (1) via telescopic transmission shafts (25, 25') and bevel gear drives (26, 26') fitted on the outsides of the wheels on both individual sets of running gear (2, 2'). Thus, when the vehicle is taking a curve, the angle formed between a leading body unit beneath which there is such a set of running gear and a trailing body unit also supported on an axle is transmitted to the steerable individual running gears units so that the pairs of wheels assume the desired radial position.

Title: Vibration damper
Inventor: MILLER DAVID
IPC: F01D5/16
Filed: 2009-03-13
Granted: 2011-03-30
Abstract: Vibration damping is important with regard to such components as hollow turbine blades in gas turbine engines. Traditionally damping has occurred through damping elements secured at the root or tip of such blades. Such damping is not optimised and results in potential problems with wear in operational life. By providing a tube of deformable material which can be located within a hollow cavity it is possible to provide an element which through friction engagement can absorb vibration energy and therefore damp such vibration. The tube incorporates a number of cuts and/or grooves in an appropriate pattern in order to define a deformation profile once the tube is expanded in location. The tube is secured in position internally upon an expandable element which is typically an inflatable device. Once in position the tube is retained in its expanded deformable profile and the engagement between the tube and the hollow cavity wall surface results in energy absorption through vibration episodes. It is also possible to provide a tube formed from a shape memory alloy which will expand of its own right in location to engage the hollow cavity wall surfaces for energy absorption during vibration episodes.

Abstract: A lance 50 for high pressure jetting of tubes of a heat exchanger core, comprises a tube 52, at least one nozzle at the end of the tube 52 for emitting a jet of water for cleaning the outer surfaces of the tubes of the core and a coupling 56 for connecting the tube 52 to a high pressure supply line. The tube 52 of the lance has an outer diameter sufficiently small to fit between the tubes of the core, and at least one elongate stabiliser bar 64, 66 is mounted on the coupling and positioned on one side of the tube with its axes lying in the same plane as the tube. The bar 64, 66 is sufficiently thin to fit between the tubes of the heat exchanger core yet sufficiently rigid to prevent lateral displacement of the tube. It is possible either to provide two stabiliser bars 64, 66 but if the tube 52 is made to rotate during use, by using motor 60, then one stabilizer bar will suffice.
