Title: Preparation of samples
IPC: B24B1/00
Filed: 1976-06-28
Abstract: 1504660 Abrading AUSTRALIAN WIRE INDUSTRIES PTY Ltd 28 June 1976 26742/76 Heading B3D  A method of preparing small samples for analysis by instrumental techniques comprises holding a representative plurality of samples in contact with each other and with a surface of a backing member and abrading an area of the samples across a surface parallel or tangential to the surface of the backing member. The instrumental technique may be optical emission spectroscopy, X-ray fluorescence spectroscopy, mass spectroscopy, ion microprobe, neutron activation, electron spectroscopy, glow discharge spectroscopy or X-ray diffraction. As described, the method is applied to the preparing of samples of wire w which are initially cleaned of scale and coatings (a), Fig. 1, and then cut into lengths (b) normally 10 to 25 mm. long. The samples are placed in contact with each other (c) on a mild steel backing plate p into which they are embedded by rolling or pressing (d); the wires may be held in position by slightly magnetizing the wire. The resultant surface of the samples is then abraded (e) so as to be smooth for presentation to the analysing instrument. In another arrangement, the wires W<SP>1</SP>, Fig. 3, are held against the flat surface F of a bar B by clamp C. The wire samples are then abraded directly or pressed and abraded to produce the surface S for analysis. In a further arrangement, a length of wire is wound on to a bar or tube and pressed and abraded to produce the analytical surface. The surface of the backing member may be roughened to give a better grip to the wire samples or have holes for location of the ends of the wires. The samples may be in a form other than wire, for example, chips, scrapings, tubing, powder, filings, millings and turnings.

The transducer is preferably a multi-electrode piezo-electric crystal and its signals are passed to an amplifier. On a multi-spindle frame a single amplifier may be associated with a bank of spindles, the signals from the separate spindles being scanned in turn. Each set of amplified signals is applied to a relay such that when the signals cease a cutter severs the yarn prior to the back rollers of the drafting head associated with the broken yarn. Audible or visual warning means may be simultaneously actuated. Specification 985,396 is referred to.

[Class 97 (iii)] In the heat meter described in the parent Specification a solution is used as the diffusion resistance or blocking medium. The meter shown comprises a sealed U-tube having a low temperature measuring limb 1 containing ethane in the space 3 above the blocking liquid, which may be a mixture of water and ethyl alcohol or a solution of a potassium halide in water. The ethane dissolves in the blocking liquid in the limb 1 and diffuses through to a space 4 which is maintained at the high temperature by a metal part 5 fixed to the heating body (not shown) and partially surrounding the space 4. The ethane separates out from the liquid in the space 4, which is provided with a small quantity of trapped gas 7 to obviate over-saturation, and passes through a narrow connecting tube 8 to the chamber 6. The U-tube is substantially surrounded by a metal sleeve 9 and housing 10 insulated from the part 5 at 12 and secured thereto by screws 13 which may be adjusted to vary the heat contact between the parts 5, 10. The sleeve 9, which carries a metal sheath 15 nearly surrounding the measuring limb 1 and carrying the scale, is pivoted to the housing 10 at 11 so that the U-tube may be tilted to the horizontal to readjust the zero point after a metering operation. A mixture of two liquids or of two gases may be used as the diffusing substance.

Title: Improvements relating to the production of hydrogen and carbon monoxide
IPC: C01B3/02
Filed: 1931-10-05
Abstract: <PICT:0390849/III/1> A mixture of hydrogen and carbon monoxide, with or without nitrogen, is produced from gaseous hydrocarbons, such as methane, and steam, with the addition of air or air and oxygen when a mixture of nitrogen and hydrogen is required for ammonia synthesis, by passing the mixed gases over preheated refractory material at temperatures in excess of 1300 DEG  C., the gases being first preheated and partially reacting while passing upward through a zone of increasing temperature; the reaction is completed while the gases pass downward through a zone of decreasing temperature.  Heating of the refractory material is effected by combustion of gas with air in a region between the tops of the zones prior to the introduction of the reacting gases, the process being interrupted at intervals to allow reheating to be effected.  Alternatively, the temperature may be maintained by the addition of oxygen, air, or air and oxygen.  Two layers of refractory material may be employed, the upper being the more refractory so as to allow of stronger heating; this layer may be formed of lumps of fused alumina or magnesia.  In the apparatus shown, two vertical chambers 1, 2 connected by a horizontal passage 3 are filled to two-thirds of their height with broken firebrick or chequer brickwork 4, 4<1> above which are placed layers 5, 5<1> of broken high temperature refractory material.  Pipes 6, 6<1> are provided at the base and other pipes 7 at the top.  In operation, gas introduced at the pipes 7 is burnt with air entering by the pipe 6 to heat the material 5, 5<1> to 1500 DEG  C., the products of combustion leaving by the pipe 6<1>.  To equalize the temperature, the direction of the flow of air and withdrawal of combustion products are reversed at intervals.  After the heating is complete, methane and steam in the proportion of one to three, are admitted at the pipe 6, the gases being preheated by the brickwork 4 and decomposed by the material 5, 5<1>; excess heat in the reaction products is absorbed by the brickwork 4<1> and utilized by reversing the flow of gases.  Air, or air and oxygen, may be admitted by the pipes 7 in such proportions as to render the process continuous and produce, after purification, a mixture of nitrogen and hydrogen for ammonia synthesis. Specifications 116,406 and 269,711, [both in Class 55 (ii), Gas manufacture &c.], are referred to.
