Title: Voice control circuit for a communication terminal
Inventor: WALKER MICHAEL
IPC: H03G7/00
Filed: 1988-05-09
Granted: 1991-04-02
Abstract: Abstract Voice Control Circuit for a Communication Terminal The circuit arrangement serves to control the volume range of the voice signals in a communication terminal, such as a video telephone with hands-free facility. In a hands-free facility, the signal-to-noise ratio is lower than in telephones with handset. To avoid singing, a prior art hands-free facility includes a volume con-trol circuit which decreases or increases the gain in the receive path as the gain in the set path increases or decreases. The problem to be solved is to utilize the maximum possible loop gain without reducing the gain in the receive path. The idea is to place behind the micro-phone (50) a controllable compandor (52) in which the signal voltages from the microphone (50) are A. compressed if they lie above a predetermined level, B. expanded if they lie below the predetermined level, and C. imparted maximum gain if they have the predetermined level. The predetermined signal level, which corresponds to the compression inset point, is varied by a control circuit (90) as a function of the ambient noise.            Fig. 12 M.Walker-G.Kohler 6/7-6/7

Abstract: Carbon steels and other hot-and cold-workable ferrous alloys generally have poor damping capacity as compared to that cast iron(gray cast iron, malleable cast iron and ductile cast iron).  This is because the graphite in cast irons helps to absorb the damping force and depresses the damping wave.  But cast iron can not be rolled into strip or sheet.  By controlling the correlated concentrations of manganese, aluminum and carbon, Fe-Mn-Al-C based alloys are made to be a .alpha.+.gamma. two-phase alloy steel with different .alpha. and .gamma. volume fractions.  With particular ferrite volumes, workable Fe-Mn-Al-C based alloys have equivalent and better damping capacity than that of cast irons especially in the high frequency side.  Such alloys suppress the vibration noise that comes from machine rooms, motors, air conditioners, and etc.     Chromium and other minor amount of elements can be added to this alloy system to improve the corrosion resistance.

The mean value is obtained from a large number of successive weighings and a computer is used for calculating the total amount of the bulk material flow. Pref. the duration of each closure cycle for the shut-off slide and hence each weighing internal is between 0.05 and 10 seconds, the intervals between the closure cycles pref. being freely selected in dependence on the bulk material flow stream.
