Title: Method for determining the attenuation and/or group delay of a signal path
IPC: G01R27/28
Filed: 1981-06-26
Abstract: A signal path to be tested is supplied with a test signal and the distortion of the signal (pulse response) produced by the path is evaluated by Fourier analysis. The test signal consists of a series of oscillations of differing frequency which are predetermined in respect of their amplitude and starting phase and is formed in accordance with the following formula
 U(t) =  SIGMA  An.cos (2 pi .n.f.t-bn> where An is the amplitude and bn is the starting phase in each case of a specific frequency nf. The resultant crest factor
 
<IMAGE>
 is reduced to a value permissible for the loading of the system by the selection of different starting phase values bn of the individual harmonic components, the starting phase values being determined taking into consideration the likely group delay of the path in such manner that a low crest factor is obtained both in the transmitted pulse and in the received pulse obtained following passage along the path.

Title: Detection of fluorescible material on sheet surfaces
Inventor: MCCOMB WALTER DAVID
IPC: G01N21/64
Filed: 1981-07-02
Abstract: To ascertain whether the surface of a glass sheet (11) which contacted the molten metal bath during production of the glass by the float process is facing in the required direction, traces of metal or metal oxides thereon are detected by fluorescence. A photoelectric device (20) senses the presence of a glass sheet and activates an ultraviolet light (21/22) which is modulated at 22 Hz. The UV light passes through a filter (23) to the sheet and the resulting visible light fluorescence is detected by a photocell (24). When satisfactory fluorescence is detected the ultraviolet light is extinguished and the sheet passed, and when fluorescence is not detected an alarm is activated. Detection of excessive ambient light by the photocell (24) also activates an alarm. <IMAGE>

Title: Method of separating ammonia and hydrogen from ammonia synthesis gases
IPC: F25J3/06
Filed: 1982-04-07
Abstract: The invention relates to a method for the complex separation of ammonia and hydrogen from the ammonia synthesis residual gases by means of partial condensation. The object of the invention is to minimise the expenditure of energy for the recompression of the hydrogen to be separated, to separate the liquid fractions (nitrogen, methane, argon, ammonia) with a minimal hydrogen content, and to obtain a maximum of ammonia from the flash gases. The problem is solved in that with a heat exchange of the individual fluids to be effected, the pressure of the let-down circuit gas is reduced in several stages, along with partial condensations, to pressures which are adapted to the suction pressures of the compression stages of the synthesis gas compressor and, in the case of the last flash stage, to the fuel gas system pressure. The problem is furthermore solved in that following an ammonia separation to be effected, the product flash gas I is adapted, with the hydrogen proportion thereof, to the suction pressure of the synthesis gas compressor and, with the liquid proportion thereof, to the fuel gas system pressure.
