Patent ZA-925955-B (ZA)
Title: Carbothermic reaction process for making nanophas s WC-Co powders.
Inventor: MCCANDLISH LARRY E
IPC: C01B32/949
Filed: 1992-08-07
Abstract: A new carbothermic reaction process is described for the thermochemical processing of nanophase WC-Co powders. The process permits shorter reaction times, reduced temperatures, and finer microstructures compared to conventional processing methods. The process builds on our experience with spray conversion processing [1], but involves 1) chemical vapor infiltration reaction of the carbon infiltrant and particle substrate to form WC-Co; and 2) removal of any excess (unreacted) carbon by controlled gasification. A feature of the carbothermic reaction process is its adaptability to conventional WC-Co processing technology, as well as to spray conversion processing technology. The resulting powder particles consist of a network of fine grains, (less than 100 nm) of WC and Co with interconnected fine porosity. Powder particles suitable for subsequent handling and consolidation are readily produced with diameters greater than 10 microns.

IPC: C22C38/00
Filed: 1996-04-25
Abstract: An abrasion-resistant steel contains (by wt.%) 0.24-0.3 (pref. 0.24-0.27) C, 0-2 (pref. 0-1 Si) 0-2 (pref. 0-1) Al, 0-2 (pref. 0.3-1.6) Mn, 0-4 (pref. 0-2) Ni, 0-3 (pref. 0.5-1.8) Cr, 0-0.6 Mo and 0-1.2 W. The steel may also contain 0.005-0.005% B, at least one of Nb, V, Zr and Ti in amt. less than 0.3% and at least one of Se, Te, Ca, Bi and Pb in amt. below 0.1%, the rest being Fe. The following relationships also apply, 4.6C + 1.05Mn + 0.54Ni + 0.66(Mo + W/2) + 0.5Cr + k ≥ 1.6, where k = 0 if the steel contains less than 0.0005% B and k = 0.5 if the steel contains more than 0.005% B and 0.6% ≤ (Al+Si) ≤ 2%. To improve their abrasion resistance sheets of the steel are heated to above austenisation temp. (e.g. 900 degrees C) then cooled to 450 degrees C at more than 1 degrees C/s, further cooled to 200 degrees C over 50 s to 60 minutes (pref. 100 s to 30 minutes) and finally returned to ambient (below 250 degrees C) in less than 3 h. This gives the steel a martensitic or martensitic-bainitic structure contg. 5-15% austenite and a hardness of 400-500 HB.

Title: Reinforcement product for use in cement boards and a method of manufacturing said product and boards
IPC: E04C5/07
Filed: 1981-07-31
Granted: 1984-05-02
Abstract: The present invention discloses a reinforcement product for use in cement boards and a method of manufacturing said product and of manufacturing cement boards using this product. The reinforcement product of the present invention comprises cross-layered webs of plastic fibres with a preponderance of fibres laid in the trans-axial direction, and continuous filaments or fibrillated tapes located between the layers to impart a high degree of strength in the axial direction. The cross-layered web and the filaments or tapes are compacted to form a reinforcement product which can be rolled up and handled for further processing on cement board forming machines. The webs of plastic fibre are formed by monoaxially orientating on extruded sheet of plastics material in axial direction, then fibrillating the sheet to form a cohesive fibre mass which is cut into lengths and carded to break up the film into a coarse fibrous mass which when stripped from the carding machine forms said plastic fibre web. This reinforcement product is made, according to the present invention in sequential steps and is either impregnated with cement or sandwiched with cement layers to form the required cement board.

Title: Apparatus for fusion joining of thermoplastic pipes
Inventor: STAFFORD TREVOR GEORGE
IPC: B29C65/24
Filed: 1985-03-25
Granted: 1988-07-27
Abstract: The apparatus increases the hydraulic pressure in rams 16 until one pipe moves towards a heater plate 14. The movement is detected by a limit switch 26 and a microprocessor-based control system 28 adds a pre-programmed value of pressure to that pressure which caused the movement (drag pressure). The total pressure is applied to force the pipe ends against a heater plate 14 to form end beads (bead-up). After heating for a pre-programmed period the control system automatically initiates plate retraction and forces the pipe ends together (fusion) for another programmed period. The applied pressure is the sum of the recorded drag pressure and a pre-programmed added pressure. Operator judgement of bead size, pressures and time periods is eliminated. Pressurised fluid is supplied to the rams 16 from a pump and accumulator combination. The sense of ram motion is determined by changeover valves controlled by the control system 28.

Date Dec. 27, 1990.Color changes in a target, such as a chemical sensor using a colorchanging indicator reagent to detect the presence of a poisonous gas, are continuously monitored by reflecting the target (10) on to a sensor (16) light originating from first one and then another light source (12a, 12b, etc), each having a different, known emission wavelength. In each cycle, direct light from the appropriate source is also collected by another sensor (14), connected in a closed loop (26) with circuitry in which the emission intensity is compared with a known reference value (38) and which adjusts the emission intensity so as to stabilize it at this constant reference value. Once this is stabilized, the reflected light intensity signal is passed to a data store (20), after which a divider (22) produces an output signal (36) representing the ratio of the reflected light intensities in two separate cycles originating from two different light sources (12a, 12b, etc). The conduct of each cycle is controlled by timing means (18). Where there are two light sources, the wavelength of the second (12b) is outside the response range of the target, that of the first (12a) being at or near the peak target response, so that all the divider output signals represent successive values of actual reflected light intensity. These signals can be processed to show the rate of color change in the target and used to operate e.g. an alarm.
