Title: Gain control apparatus for digital telephone line circuits
IPC: H04B3/04
Filed: 1980-11-28
Abstract: There is disclosed a digital gain control particularly adapted for use with digital signals propagating in a telephone line circuit. The gain control is positioned in the circuit to respond to a digital signal manifesting a plurality of words, each having a given number of bits N and indicative of a weighted value of an analog signal. The digital signal is multiplied by a word coefficient having a number of bits M indicative of a gain factor to be imparted to the digital signal. A product signal is provided containing M+N bits. The least significant bits are removed to provide an output signal of N bits possessing the desired gain. The discarded bits are employed via a feedback loop and are added to the next word product, which is then used to provide a next output signal. The feedback loop assures that each output signal is a close approximation to the input signal as gain controlled by the desired gain factor.

Patent ES-8306969-A1 (ES)
Title: A bow-type continuous-casting method and apparatus.
IPC: B22D11/128
Filed: 1982-06-25
Abstract: The apparatus has a low height, a curved mold (6), and a multi-point straightening zone (10). The prior art involves a problem in that the straightening rolls (7) are not reliable due to a high load which is generated during a non-stationary casting period during which the top or bottom section of a strand (3) is conveyed through a multi-point straightening zone (10). One selected pair of straightening rolls (11) is shunted from the defined radius (Rn) of the curve by means of cone-shaped springs (28) or hydraulic cylinders so that the distance between the two pairs of straightening rolls (11) which are engaged in straightening during a non-stationary casting period is increased. The reliability of the straightening rolls (11) is so enhanced that high-speed and moderate-cooling casting in a low-head CCM can be directly combined with hot-rolling of the strands (3).
