Abstract: The invention relates to a method for recovering sodium chemicals from green liquor by precarbonating green liquor by means of flue gases, by bringing a precarbonated solution into contact with a sodium bicarbonate solution and by stripping hydrogen sulphide from the so obtained reaction mixture by means of steam, for producing hydrogen sulphide gas and a sodium carbonate solution, which sodium carbonate solution is so pure, in relation to sodium sulphide that it can directly be led into the washing of the flue gases and into a carbonation stage, for producing the sodium bicarbonate solution. In order to save steam and sodium carbonate all precarbonated solution is not treated to the sodium sulphide free solution, which is required by a scrubber, but a part is discharged at higher sodium sulphide content by dividing the stripping into two stages which take place one above the other in the same tower, whereby a part of a solution obtained from the first stripping stage is led directly into the second stripping stage and the steams containing hydrogen sulphide, obtained from the second stripping stage are led directly into the first stripping stage.

Abstract: A device comprising a series circuit consisting of a plurality of thyristors connected in series, and a reverse-blocking semiconductor element such as a diode connected in an antiparallel relationship to the series circuit. The device further includes means for detecting whether a sufficient turn-off time is secured for each of the thyristors anterior or posterior to a reference moment at the zero point of a current flowing in the diode, and means for turning on the entirety of the thyristors when the sufficient turn-off time is not secured. Since none of the thyristors is turned off in the state where the turn-off time is insufficient, it becomes possible with certainty to achieve exact prevention of a fault that one or more thyristors, turned off earlier than others are led to breakdown by an overvoltage.

Abstract: The compensator includes optical transmission and receiving components (6,7) which are positioned separately to the cannon, and a reflection component (5) placed on the cannon itself. The latter component provides a reflection, dependent on the parallelity error, to the receiving component of radiation (11) emanating from the transmitter. The receiver is responsive to the reflection alteration caused by the error. The radiation is constituted by a small part of a laser light coming from a transmitter which is actuated when a distance measurer (4) is initiated, the transmitter acting as reference to the line ofsight. Alteration in the reflection enables the receiver (6) to produce a corresp. effect on a calculator (9) forming part of the aiming equipment, this effect being used as a parameter for the cannon aiming.

Abstract: There is disclosed several forms of adjusting mechanisms for a headlamp, or the like. Basically, the mechanism includes a one-piece molded housing member defining gear receiving chambers disposed transversely to each other with said chambers intersecting at a peripheral location. A first drive gear member is disposed in a first one of said gear receiving chambers, and a second adjusting gear member is disposed in the other chamber, with said gear member being engaged at the location where said chambers intersect. A drive member is coupled with the first, drive gear and extends from the housing. An adjusting screw is coupled with said second, adjusting gear for linear movement and extends from the housing for engagement with a headlamp. Accordingly, upon rotation of the drive gear linear movement will be imparted to the adjusting screw by the gear members, which linear movement produces adjustment of a headlamp assembly relative to the automobile frame. In several alternate embodiments, a cantilevered spring member is used to engage the gear members to prevent inadvertent rotation thereof.

Abstract: A shoe construction for providing girthing support to the midfoot region of the foot is disclosed. The present invention provides for adjusting the perimeter of the transverse girth of a shoe in the midfoot region under varying conditions of loading. When the foot is in an unloaded condition, the dynamic girth of the present invention has no effect on the original girthing tension. Then as the foot is loaded and everted, girthing fibers or straps are forced into an undulating surface. When the everted foot becomes loaded completely, the girthing straps become mated with the undulating surface in close contiguous contact, thus pulling in the girth straps and producing maximum tension on the midfoot region. The undulating surface may be provided in the outsole so as to be positioned below the girthing straps or, alternatively, in a portion of the shoe positioned above the girthing straps. The girth structure of the present invention creates girthing tension dynamically to prevent excessive eversion when the foot loads the shoe.

Abstract: A gas concentration method and a gas concentrating plant, especially for the separation of oxygen out of air by means of adsorbtion. According to the invention air is first compressed by means of a compressor (1) and dried by means of a dual tank moisture adsorbing unit (14, 15) in order to achieve for the gas adsorbing unit (34', 35) feed air, dew-point of which is about -40 DEG C. The major part of the oxygen-rich gas coming out from the adsorption unit is led forward and the lesser part of said oxygen-rich gas is recycled unit in order to regenerate the adsorbtion unit by removing the nitrogen-rich gas bonded to the adsorption material of the adsorption unit. Said gas flows: compressed and dried feed air flows to adsorption units (14, 15; 34', 35), oxygen-rich gas flows to be recycled and led forward, nitrogen-rich gas flow to be removed from the adsorption unit (34', 35), are controlled and regulated by means of pneumatically operating regulation and control elements (10...13, 28...31, 36, 37, 52...64), whereby the separation of a gas component, advantageously oxygen out of air, is reliably and safely carried out also in humid, cold and/or explosion risky conditions.
