Patent FI-973705-A (FI)
Inventor: PITKAENEN MAIJA
IPC: D21H23/08
Filed: 1997-09-16
Abstract: The present invention concerns a process for preparing a paper web. According to the process a pulp is formed from a fibrous raw material, a web is formed from the pulp and it is dried on a paper machine. According to the invention the pulp is formed from a mechanical pulp produced from a peroxide bleached mechanical wood raw material of the genus Populus, the pH of stock of the mechanical pulp being set at 6.8 to 7.2 and the machine pH at 7.1 to 7.5 and the conductivity of the stock being set at 1000 to 1500  mu S/cm. By using a relatively low pH value and a narrow pH range it is possible to reduce the sensitivity to disturbances of the paper making process. According to the present invention a mechanical aspen pulp can be combined with chemical pulp for preparing base paper of fine paper, whereby the mechanical pulp gives a high conductivity on the machine which improves the stability of the wet end and enhances water removal.

Filed: 1998-10-08
Abstract: The invention relates to a process for measuring a vital function, and a measuring device which can implement the process. The measuring device receives as signal episodes pulses, for example, which have been generated by a heart. In an averaging unit 404, the measuring device forms a coherent average of the signal episodes in order to determine the wave form of the signal episode. The measuring device advantageously also comprises a suitable filter 406, the pulse response of which is based on the coherent average of the signal episode. <IMAGE>

Successive gaps, 46, 48, scanning the same digital track in a magnetic record are associated with complementary magnetic circuits 10, 12, all or parts of which are periodically saturated by modulators, 18 or 38. In Fig. 1, an output, at double the modulation frequency is produced in a winding 16 when an NRZ changeover is passing or stationary between the gaps. In Fig. 4, two half-track heads with staggered gaps and opposed series-connected windings react as in Fig. 5 to the passing of a changeover point to give a sharp output pulse of length equal to the gap-spacing. A stacked multi-track head of either type may share a single modulator threaded through all the head elements.

Title: Position finding receivers
IPC: G01S1/30
Filed: 1973-01-09
Abstract: 1424752 Radio navigation S C MURISON 9 Jan 1974 [9 Jan 1973] 1174/73 Heading H4D In a hyperbolic navigation receiver, of the kind having master (11) and slave (1, 10) (e.g. Red and Green) channels, feeding the corresponding received master and slave signals to phase detectors 2, 3 any difference in the phase shifts imparted on a signal by the master and slave channels will cause an error. The Specification therefore proposes the automatic removal of any such phase shift differences by removing the incoming slave signals from the inputs of the respective slave channels, deriving phase locked signals at the slave frequencies from the still received master signal at the output of the master channel, substituting these derived signals for the removed signals and using any deviation,of the phase detector's outputs from zero to adjust respective variable phase shifters in the slave channels. As shown in Fig. 1, the red, master and green frequencies are 127¢, 85 and 113 1/3 kHz respectively. The respective channels 1, 11, 10 frequency multiply these signals to give two signals at 225 kHz for the red/master phase comparison at 2 and two signals at 340 kHz for the green/master phase comparison at 3. For the phase shift correction, the inputs of the slave channels are disconnected from the antenna 13 and connected to a harmonic generator for producing the correct frequency signals from the master signal. The outputs of the phase detectors are analysed by zero detectors 4, 6 so that a correcting signal can be fed to the voltage controlled capacitor diode phase shifting circuits in the slave channels. Zero detectors 4, 6 may be binary registers for which a correct phase adjustment of the channels gives a 0 for all stages, a small phase difference in one sense gives a 1 in the least significant stage, and a small phase difference in the opposite sense gives 1's in all the stages. The sense of the phase difference can thus be determined by logic circuit analysis Fig. 2 (not shown) of the states of the most and least significant stages of the register.
