Abstract: 1. Procedure for the refining of a pulp mixture or equivalent in a refiner comprising  oppositely placed refiner blades (1, 2), of which the rotor blade (1) rotates and the stator blade (2) is stationary, a pulp refining zone being formed between the blades. In the refiners currently used, there is no adequate provision for ensuring that the refiner will refine that fraction which has not yet been refined or that the fractions already refined will not be over-refined. The procedure of the invention solves this problem in that, by making use of the forces generated by the rotation of the rotor blade (1), the pulp mixture is separated into fractions or part of the pulp mixture is directed away from the area of the refiner blades for fractionation.

Abstract: An automatic masking system is used in an optical time domain reflectometer for implementing a method of compensating for relaxation transients in an optical receiver in the OTDR. The masking system drives an optical modulator that masks the optical receiver from high amplitude optical pulses in the return reflected light from a fiber under test. A masking pattern corresponding to the high amplitude optical pulses is generated from a first acquisition of data with the receiver unmasked from the return reflected light. The masking pattern is stored and used for generating a signal from the masking system to the optical modulator for blocking the high amplitude optical pulses in the return reflected light during a subsequent acquisition of data. In a third acquisition of data of the return reflected light, the optical modulator masks the receiver from the return reflected light. Combining the acquired data of the blocked return reflected light with the acquired data with the high amplitude optical pulses blocked, produces an output free of relaxation transients produced by the receiver. Combining the high amplitude optical pulse data from the first acquisition with the output from the subtracted acquisitions produces an output representative of the return reflected light.

The first and second keys are presented with an access sequence from the computer in the software which is desired to be controlled generating outputs which are applied to an algorithm decoder which provides a control key which is used to protect the software from unauthorized use. The control key is the resultant of the algorithm decoder and the first and second keys. One of the keys is supplied with the hardware under the control of the developer whereas the second key may be supplied with the hardware device but is not restricted to the hardware device and may be entered through a separate port of the computer. The algorithm decoder can be included in any part of the software, the computer hardware or any combination thereof. Many combinations of the first and second keys may be designed to produce the same control key when decoded. One of the keys may be altered without regard to security, but there are certain values of the second key for each given value of the first key which will operate the software. Providing a plurality of first and matching second keys which produce the plurality of different valid control keys allows the use of additional software that works in conjunction with the original distributed software acquired at a later date without the addition of additional hardware devices.
