Title: Automatic control system for a chimical process epecially awet process phosphoric a cid plant
Inventor: STEPHEN W HILAKOS
Filed: 1994-07-25
Granted: 1994-12-25
Abstract: Constant efficiency operation of a wet process phosphoric acid plant can be obtained by controlling the specific gravity of the filtrate from the last washing of the gypsum cake. The filtrate from the last washing of the gypsum cake also is called the first pass filtrate. The specific gravity of this first pass filtrate provides an indication of the overall filter efficiency and the loss of water-soluble phosphoric acid to the gypsum waste stream. The specific gravity of the first pass filtrate is controlled by adjusting the rate at which product slurry from the attack tank is fed to the filter. This product slurry feed rate is affected by the mechanical performance of the filter and the filterability of the gypsum crystals, which, in turn, is affected by operating conditions in the attack tank. Therefore. the feed rates of phosphate rock, sulfuric acid, and water, are controlled to produce the desired attack tank operating conditions and to maintain attack tank level. Each of the primary processing steps. i.e., operation of the attack tank and operation of the filter, is controlled io maximize plant efficiency. By minimizing phosphoric acid iss and optimizing operation of the attack tank in accordance with the invention, plant efficiency is maximized.

Abstract: in a system for recording and reproducing digital signals on a magnetic tape (2) using a rotary head (1A, 1 B), in which the signals are recorded as a series of oblique tracks (5A, 5B) without guard bands, a pilot signal that controls tracking alignment of a playback head (1 A, 1 B) is recorded at a particular position in a specific pilot signal record region, different from the information signal record region. An erase signal having various recording lengths is also recorded in the pilot signal region such that a start position of the erase signal corresponds substantially to a centre portion of the pilot signal on the adjacent track (5A, 5B). When the recorded tracks are reproduced by a playback head (1 A, 1 B) having a tracing width greateer than the track width, the pilot signals from the adjacent tracks (5A, 5B) will be sampled by sampling pulses generated in response to the reproduced erase signal and compared in level, and the comparison output will be used to control the tracking alignment of the playback head (1A, 1B).
