Abstract: A heat pump with high coeffecient of performance. The heat pump includes a compressor (6), a condenser (2), and an evaporator (5). The condenser (2) is connected to a water accumulator (3). A pump (15) circulates the water from the accumulator and through the condenser (2). The evaporator (5) is connected to a heat medium of a suitable kind with which heat exchange takes place. The evaporator includes a plurality of relatively short tubes (22) connected in parallel. Each tube at the lower end thereof includes separation means for oil, which is directed via a separate duct (26) to a separate oil inlet of the compressor (16). The tubes of the evaporator includes restrictions (22b) spaced along the length of the tubes. The restrictions are accomplished by the tubes being compressed while rotated. The rotations are preferably in different directions in adjacent compressions. These compressions substitute the restriction means in a conventional heat pump, and consequently the restriction means may be said to be distributed over the evaporator. (Fig. 1)

Abstract: A hydraulic or pneumatic oscillating piston motor has a housing (1), a driven shaft (2) mounted in the housing for rotation and an oscillating piston (3) that is fixed to the shaft. The piston has two lever arms (49,8) having pressure areas of different size, which arms are sealed with respect to the housing (1) dividing the housing (1) into two working spaces (4,5) into which a pressure medium can be introduced. The oscillating piston (3), actuated by the pressure medium, is free to oscillate back and forth through a maximum angle of rotation which is determined by means of a stop (38) and the housing. The first lever arm is designated in the form of a bushing (49) whose shell surface along its external periphery is at least partly surrounded by a coaxial shell seal (64). This seal has uniformly distributed, rib-like sealing lips (75) along its periphery and interacts with a opposite surface (9) attached rigidly to the housing (1).

Abstract: In a motor saw with an engine unit separated from a handle system by devibration elements, difficulties arise by in the use of a link system of iron plate or lever elements in performing a movement transfer without "backlash" etc. As a consequence thereof there is an involuntary speeding of the engine, great inherent moving play, propagation of vibrations between the carburetor and the finger grip, and sizing of elements adapted to every saw model. The invention eliminates these inconveniences by introducing a gear-driven, flexible shaft, e.g. a tightly wound helical spring which can transfer movements to the throttle by turning. The influence of relative movements between the engine and the handles can thus be eliminated.

Abstract: The device is for adjustment of the phase angle of a light signal transmitted in a fibre (F), with the fibre in a part of its extent forming a loop. An elongated component encloses the part of the fibre forming the loop, and the fibre with the elongated component are fixed in a fixture component (F1,F2) at the elongated component (C) end points. The end points form an axis around which the loop is rotated, and the fibre together with the elongated component receive a twisted movement corresp. to the rotation. The elongated component is elastic and the twisted movement is transmittable in the whole length of the loop. The twisted movement in the elongated component activates the fibre. The twisted movement is transmittable to the complete length of the loop in the fibre and is neutralised relatively to the elongated component. The fibre is in an unactivated state and the loop is rotatable through a suitable number of turns, permitting the light signal phase angle to be adjustable adequately and continuously.

Abstract: Cellulose (paper) pulp is bleached by first washing it in a first washing stage using a first wash liquid, passing the pulp from the first washing stage to a peroxide bleaching stage (either unpressurized or at superatmospheric pressure), after the peroxide bleaching stage washing the cellulose pulp in a second washing stage using a second wash liquid and producing a filtrate, and then treating the filtrate and bringing the filtrate to the first washing stage to be used as the wash liquid in it. The filtrate is treated by bringing it into intimate contact with an oxidizing gas to oxidize contaminants in it. The method typically includes an ozone bleaching stage either before or after the peroxide stage, in which ozone containing gas is used to bleach the pulp and produces an off gas containing residual amounts of ozone (typically in an oxygen carrier gas). This off gas with residual ozone (which may be supplemented by ozone from a low cost ozone generator) is preferably used as the oxidizing gas for the filtrate, and can be used to remove odors from other pulp mill fluid streams. The filtrate may be treated in a vertical tank having a gas sparger at the bottom in which case the oxidizing gas is introduced into the vertical tank through the gas sparger, and the tank is maintained at either atmospheric or superatmospheric pressure. Alternatively a gas scrubber, or other conventional gas-liquid contactor, can be used to treat the filtrate.
