Inventor: RICHTER C F C JOHAN
IPC: D21C7/00
Filed: 1991-04-02
Abstract: In a continuous digester for paper pulp (comminuted cellulosic material), abrupt variations in high pressure steam flow are minimized. First and second vertically spaced annular screens are provided in a vertical vessel. Each has an annular header associated with it and first and second circumferentially spaced liquid outlets associated with each header. The first outlet for the first screen is generally vertically in line with the first outlet for the second screen, and the second outlet of the first screen is generally vertically in line with the second outlet of the second screen. Simultaneous withdrawal of liquid from the first outlet of the first screen and the second outlet of the second screen takes place, and then is terminated, and then simultaneous withdrawal of liquid from the second outlet of the first screen and the first outlet of the second screen takes place, and then is terminated. This withdrawal sequence is repeated continuously. Each header is divided into two substantially equal volumes by vertical walls with an outlet provided at the circumferential center of each volume. Any material that passes through the screens flows under the force of gravity from the Vertical Walls to the outlet associated with that header volume due to the provision of downwardly sloping bottom portions in each volume.

Abstract: The process comprises the following stages: preparation of a solution containing at least one solvent and at least one solvent-soluble polymer precursor, the total precursor concentration being from 0.05 to 2 mol/l; high-frequency ultrasonic spraying (12), in a leakproof closed reactor (18), of the solution above the substrate (24) resulting in the deposition of a sol of the said precursor on the substrate, the latter being kept at a temperature below the boiling temperature of the solvent, and drying (28) of the deposited sol to evaporate the solvent and thus to form a solid layer of the said polymer. In particular, the precursor is a monomer. Baking of the polymer deposit may be optionally performed with a view to obtaining an inorganic deposit and more especially metal oxides in the form of glass, of vitreous ceramic or of ceramic. <IMAGE>

Abstract: A PLL control method is disclosed in which the ratio between the output frequency and the input one is a rational number. It is characterized by the presence of a control system of the programmable frequency divider present in the PLL. 
     On the ground of the phase error produced by a phase comparator, an estimate of the oscillator phase error is carried out from which a frequency divider driving control signal is obtained. The PLL comprises a phase error reproducer (ERRFAS) for reproducing the output of the phase comparator of the PLL and a predictor circuit (PRED) for providing said oscillator phase error. Both the phase error reproducer and the predictor are consisted by accumulators. A control system (CONTR) is fed with the output of theses accumulators and generates the frequency divider control signal. The goal of the control system is to transform the low frequency Jitter on the PLL output signal into high frequency Jitter easily eliminable through a suitable signal filtering.
