Title: Method and apparatus for electrolytically etching metals to reveal internal quality.
Inventor: KELLY JOHN HAMILTON
IPC: G01N33/20
Filed: 1992-08-05
Abstract: The internal quality of continuously cast and other steel samples in the form of ingots, billets, blooms, slabs and bars is determined in rapid manner to enable potentially problem-causing casting conditions to be identified and corrected in timely manner. A steel sample from the casting, after grinding to remove any heat-affected zone and to provide a desired degree of surface roughness, is anodically etched using dilute hydrochloric acid at ambient temperature to etch away metal from the surface to reveal the internal quality. After removal of the sample from the etching apparatus, the sample is washed, dried, and visually examined to determine the internal quality.

IPC: C08L39/00

Abstract: Hydrogel provided as tablets capable of regulating without dissolving, any pH of an aqueous solution, to finally convert the pH to 7. These tablets may be removed from the solution at any time without modifying the pH and they may be reused after washing. The buffering speed depends on the initial pH and may be controlled by modification of the mass and the composition of the tablet. The hydrogels are obtained by copolymerization of a vinylheterocyclic and divinylic comonomer in an aqueous solution at a temperature of about 60 DEG C, in an inert atmosphere. By adjusting the proportion of cross-linking material and the concentrations of comonomers, the cross-linking of the hydrogel may be regulated according to the desired utilization of the product.

Abstract: The reversible gear machine has two gearwheels (26, 29) which mesh in external engagement and whose shaft journals are supported in bearing bodies (16 to 19). These are forced, by means of bearing areas (75 to 80) raised on their outsides, against the gearwheel lateral faces in a sealing manner. The bearing areas are delimited by a sealing arrangement (52) which is inserted in a corresponding groove (50, 50A, 50B). Near the outsides, the groove has sections (50B) of greater depth which in a stepwise manner merge into the zones of lower groove depth (50A). Disposed on the seals near said steps (74) there are elastic extensions (73) which, depending on the differential pressure, are forced against the step (74) or forced away from it. Thus a bearing area can form, below the sealing arrangement, which has the shape of a figure three which is open towards the area at the lower pressure. <IMAGE>

Abstract: A Stirling engine in which a displacer plate 5 can be moved backwards and forwards between two housing plates 1, 2, the said displacer plate being without sliding friction relative to the ends 10 of the housing along the circumference, is known. It is desirable here for the Stirling engine to be designed for larger output ranges with a reduced outlay on construction by making the housing plates and the displacer plate as large as possible, taking into consideration the resistance to pressure of the housing. This is achieved by virtue of the fact that the two housing plates 1, 2 are held at a distance from one another by struts 3 arranged in a distributed manner, the struts extending at right angles to the displacer plate 5 and passing through the latter, and by virtue of the fact that the displacer plate 5 is guided along its end edges relative to the ends 10 of the housing by linear rolling diaphragms 9. The housing plates are reinforced over the surface area by the struts and the displacer plate is guided exactly parallel with regard to the struts by the rolling diaphragms. <IMAGE>

Abstract: A laser (2) of an optical transmitter (1) for information transmission, particularly for the transmission of analog broadband signals for CATV, can be amplitude-modulated with a useful signal (N) in two different ways. In direct modulation, an unwanted additional frequency modulation occurs. In indirect modulation by means of an optical intensity modulator (3), Brillouin backscatter occurs in an optical fibre of the transmission link following the optical transmitter (1) even at transmitting powers of about 10 mW. Both types of modulation lead to distortion of the transmitted signal. To circumvent the disadvantages of the two types of modulation in a technically simple manner, the carrier emitted by a laser (2) is indirectly modulated with a useful signal (N) and the laser (2) is additionally weakly directly modulated with a dispersal signal (V). The weak direct modulation leads to a continuous slight change in the wavelength of the optical signal so that the Brillouin backscatter is reduced but, at the same time, dispersion distortion is avoided. <IMAGE>

Abstract: A gas cell for measuring the chemical constituents of a gas sample generally includes a central body portion having a hollow interior and first and second end plates sealing off the hollow interior. Each end plate includes an integrally formed concave mirror for reflecting an optical beam back and forth through the interior of the gas cell. Typically, one end plate includes two objective mirrors while the other end plate includes a field mirror optically oriented towards the objective mirrors for reflecting the optical beam therebetween. One of the end plates includes a pair of windows, one of which is used to introduce the optical beam into the gas cell interior and the other through which the optical beam exits after making multiple passes between the mirrors. The absorption spectra of the various chemical constituents within the gas sample can be measured by analyzing the exiting beam in a conventional spectrometer. The central body portion includes a pair of datum surfaces which abut against reference surfaces on the end plates to ensure that the distance between and the orientation of the mirrors remains constant, even when the end plates are removed for servicing or exchanged with other end plates having mirrors with different optical orientations. A gas inlet passageway and a gas outlet passageway communicate with the interior of the gas cell so that sample gas may be introduced into and removed from the cell.
