Abstract: Respirator intended for pulmonary patients and for indisposed or unconscious persons. The respirator comprises a drug atomizer (13), a supply pressure source communicating with the drug atomizer (13) for conducting air or oxygen, an injector (21) communicating with the drug atomizer (13), and control valves (15, 16) for regulating the atomizing rate of the drug atomizer (13), respectively the respiration pressure. The respirator is composed of a modular system comprising a basic unit consisting of a drug atomizer (13) and a control valve (15) thereto connected, by the aid of which the air or oxygen flow to the drug atomizer (13) can be regulated, and a first tube-like connector (18) which by one end can be connected to the inlet connector (19) of the control valve (15) and by its other end to a connector (20)) communicating with the supply pressure source. To the modular system has been connected an injector (21) connected to the drug atomizer (13), a second tube-like connector (22) connected by one end to the respiration pressure control valve (16) and by its other end to the injector (21), and an exhalation valve mounted between the mouthpiece (11) and the drug atomizer (13) and by the aid of which the counterpressure to exhalation flow can be steplessly regulated. The respiration pressure control valve (16) has been placed in a branch line (35) between the tube-like connectors (18, 22). The first tube-like connector (18) communicates with the supply pressure line (26) through an electrically controlled magnetic valve (36). The respiration pressure control valve (16) likewise communicates with the supply pressure line (26) through the electrically controlled magnetic valve (36). The control means (37) for the magnetic valve (36) comprises a first timing means for setting the operating period of the respirator to conform to the patient's respiratory rhythm, respectively a second timing means for regulating the rest period of the respirator to conform to the patient's respiratory rhythm.

Abstract: A method for bringing a digester up to cooking temperature efficiently and rapidly wherein wood chips are packed in the digester, covered with a hot spent liquor, and then a hot liquor displacing liquid is used to displace the hot spent liquor from the digester and send it to an alkali adjustment zone in an accumulator. After the hot spent liquor has been displaced, the hot liquor displacing liquid is passed through the digester and into a lower portion of the alkali adjustment zone. Hot liquor is constantly passed from a constant volume heating zone into the alkali adjustment zone by overflow or otherwise. Hot liquor at the cooking temperature is passed from the top of the heating zone into the bottom of the digester and relatively cool liquor after passage through the digester passes from the top of the digester to the bottom of the heating zone. This type of circulation is continued until liquor leaving the top of the digester is at the cooking temperature whereupon the circulation is terminated and the heat content of the liquor in the heating section is increased by passage through a separate heat exchanger.

Date Jun. 14, 1990.There is described a method of drying air with the aid of a rotor (6) which rotates continuously in a housing (2) and which incorporates moisture-sorbent means. The housing (2) has mounted therein a casing (12) which is located on the low-pressure side of the rotor and provided with heat-emitting devices, for instance electrical elements (15), for delivering radiant heat directly to the rotor interior. The heat required for regeneration is therewith delivered at high temperature, which increases the heat yield. The part of the rotor (7) which is normally the most difficult to regenerate is therewith heated to a temperature of 250 DEG -300 DEG  C. Since the volume of regeneration air is smaller than normal, the air is heated to a temperature which is much higher than normal in all parts of the rotor, so as to result in effective removal of the moisture present. The invention also relates to an air dryer by means of which the method can be put into effect.

Abstract: The present invention relates to a method of regulating or adjusting the transmission power when transmitting signals between a mobile station and a base station in a digital mobile telephony system. The output power is regulated with the intention of constantly maintaining the transmission power at an optimum level, by which is meant that the transmission power is as low as possible such as to prevent unnecessary disturbance of neighbouring channels transmitting information on the same frequency, but sufficiently high for the transmitted information to be interpreted in the receiver. According to the inventive method, the measurement values of signal strength and signal-transmission quality are collected (1). The mean values of the signal strength and transmission quality (2) are calculated on the basis of the collected measurement values. With the aid of the calculated mean values, there is calculated an anticipated value of signal strength (Z_SS) and transmission quality (Z_QQ) at the next time-point t1, provided that the transmission power is maintained unchanged in relation to the transmission power at the present or instant time-point (t0). Finally, the transmission power (MS_PWR) at the next time-point (t1) is regulated on the basis of these anticipated values (Z_SS, Z_QQ). The transmission power (MS_PWR) is increased when the anticipated transmission quality is poorer than the desired quality and is increased when the anticipated quality is higher than the highest permitted quality or when the anticipated signal strength is greater than the maximum permitted value. The transmission power is otherwise maintained unchanged. <IMAGE>
