Abstract: 1375859 Altering physical properties A G HEBEL JNR and A G HEBEL 6 Dec 1971 [7 Dec 1970] 56505/71 Heading B3V In a method of stress relieving a metallic object, the object is first vibrated over a range of frequencies to produce a plot of vibrational response as a function of frequency comprising at least one hill, which has a resonant peak and slopes extending upwardly and downwardly towards and away from the peak respectively with increasing frequency, and to perform the stress relief the object is vibrated at a selected frequency within a range defined by one of the slopes.  A metal beam 10 is supported by rubber pads 14 and a vibrator 16 is clamped to the beam at position A. The vibrator comprises a variable speed motor driving an eccentric and the vibration is detected by a pick-up 18 also clamped to the beam. The motor is run through a speed range, which results in the beam vibrating through a frequency range of 0-10,000 CPM, and the amplitudes indicated on a meter 26 are plotted against frequency to give a curve 30. Effective stress relief can only be given by vibrating the beam at a frequency within a range defined by one of the slopes 36a-36d or 38a- 38d. A preferred location is approximately one third the way up one of the upward slopes 36a- 36d and best results are obtained where the downward slope is steep relative to the upward slope, i.e. at location 39. During the stress relieving operation, the frequency peaks shift to the locations shown in curve 44. This shift is shown as a change in meter reading and when this has stabilized, stress relief is complete. The vibrator is moved successively to positions B, C, D and the operation is repeated. Other metal articles may be similarly stress relieved, e.g. spoked wheels, flat discs and tubular rails joined side-by-side by angle sections, Figs. 2-4 (not shown).

Abstract: 1327187 Automatic control of proportion SOC NATIONALE DES PETROLES D'AQUITAINE 16 Dec 1971 [18 Dec 1970] 58488/71 Heading G3R A unit 23 for producing sulphur by the oxidation of hydrogen sulphide is automatically controlled to maintain a desired parameter based on the sulphur compound content of residual gas by adjusting the amount of oxygen added to the hydrogen sulphide at the inlet in response to a signal calculated from measurements made of the hydrogen sulphide and oxygen at the inlet corrected by a signal calculated from the actual value of the parameter obtained by analysing the residual gas at the outlet. The first calculator, 22, receives signals of the flow, pressure and temperature, measured at 2, 3, 4 of the hydrogen sulphide (impure) introduced at 1, also signals of its actual hydrogen sulphide and methane content derived by analyses by chromatograph 6 of a sample taken at 5, and signals of the flow, pressure, temperature and humidity of oxygen (e.g. as air) introduced at 11. The operation of the calculator is not disclosed, but is said to model the process. The theoretical oxygen requirement signal appears at 35 and is combined (i. e. corrected) at 34 with a signal 33 from the second calculator 32 in which the actual mol ratio of hydrogen sulphide to sulphur dioxide (or the sum of these quantities) is derived (from signals from a second chromatograph 30 which analyses samples 28 of the residual gas emerging at 24) and is compared with a reference value. The resultant signal 36 operates a valve controlling additional air admitted at 18. The calculator 32 (again unspecified) is said to take into account proportional, integral, and first and second "pseudo-differential" coefficients. There may be a further calculator 41 which derives the rate of conversion of hydrogen sulphide into sulphur from signals from the two analysers 6 and 30. The residual gas is finally incinerated at 25 and exhausted at 27.
