Patent SE-8505108-D0 (SE)
Inventor: KOHL A L
IPC: C10J3/46
Filed: 1985-10-29
Abstract: A process for recovering the energy and chemical content of an aqueous black liquor utilizing a reactor containing a drying zone located above a gasification zone. The reactor contains a bed of porous solid carbonaceous material in the gasification zone. Heat losses are restricted, preferably from both zones, by the provision of a layer of insulating material about the reactor. An oxygen-containing gas is introduced into the gasification zone in an amount less than about 60% of that required for complete combustion of the black liquor such that there is produced partial combustion and gasification reactions sufficient to maintain the temperature at an upper surface of the bed in the range of from about 870 DEG  to 1200 DEG  C. and to form a hot combustible gas which rises from the gasification zone. A concentrated black liquor containing alkali metal, oxysulfur compounds is introduced into the drying zone and the water contained therein evaporated by contact with the hot gases rising from the gasification zone. In the drying zone there is produced a reduced temperature product gas and dry black liquor solids which fall onto the surface of the bed in the gasification zone. The dried black liquor solids are converted into the hot combustible gas which rises from the gasification zone and alkali metal salts which melt and permeate through the bed. The product gases are withdrawn from an upper portion of the drying zone, and a melt in which the sulfur content is about 80% in the form of alkali metal sulfide is withdrawn from a lower portion of the gasification zone.

Abstract: A reverse gear mechanism features input and output shafts, (1, 2) which are both connected via a planetary gear assembly consisting partly of a ring gear (7) on a cover (8) that is connected to the output shaft (2) via a primary spline coupling (9,10), and partly of a sun gear (11) which is connected with torsion resistance via a secondary spline coupling (12, 13) with each able to shift axially relative to the input shaft (1). A number of planetary gears (14) integrating with the sun gear (11) as well as the ring gear (7) are positioned on a carrier (16) that is freely rotational relative to the input shaft (1) as well as the cover (6). In a first position, the cover provides a connection with torsion resistance between the shafts (1, 2) via the spline coupling (9, 10). In a second position the input shaft (1) releases the spline coupling while the planetary gear carrier (16) is braked relative to the input shaft. The output shaft is thereby made to rotate in the opposite direction of the input shaft and at a reduced rotational speed.<IMAGE>

Abstract: A connector for rotating belt-like members that are subjected to tension. The belt-like members are provided with reinforcements that form a unit. Furthermore, the members are made essentially of rubber or rubberlike materials, and have two ends. Two U-shaped fittings that are interconnected in an articulated manner are provided, with each fitting being provided with two legs having surfaces that face one another. In the mounted state, a given one of the ends of a belt-like member is disposed between the facing surfaces of the legs of a given fitting, whereby the fitting is secured to the belt-like member via fasteners. The facing surfaces of the legs are each furthermore provided with projections that extend transverse to the direction in which the member rotates. One of the projections of a given one of the legs is disposed across from the space between two projections of the facing leg. In a mounted state, the thickness of the belt-like member is such, and the distance between facing surfaces of the legs is such, that the unit is deformed in a wavelike manner in conformity to the configuration of the legs.

Abstract: Appts includes a polyvinyl fluoride film adhered to the glass of a diving mask, and enables the glass to function as a loudspeaker. To the film is connected a sound amplifier which is battery-operated. The amplifier receives its input signal from a sound microphone fixed to the interior of the diving mask. The microphone signal can, if required, be transmitted through a phase-shifter prior to entry into the amplifier input. This reduces the tendency to feedback where the amplification is excessive due to sound waves circulating from the glass to the microphone. The amplifier activates the film which in turn transmits signals to the surrounding water. The electronic equipment and battery involved need to be protected against ingress of water, and are enclosed in a watertight box.

Abstract: The present invention is providing a method and an operating arrangement to effectively obtain protection detection of an object, especially a person, positioned close to a machine in motion or a moving part of a machine in the case of accidental collision or contact by the machine with the person without the use of any electric cabling arrangement between the person and the machine. This is accomplished by detecting an induced AC signal in the body of the person transferred to the machine at the moment of ohmic contact by utilization of an insulated conducting sensor surface covering the total surface of the machine. This sensor surface is connected to an electronic circuitry outputting signals to the power and controlling unit of the machine for stopping or reversing its motion in a case of dangerous contact between the machine and the object, i.e. a person.

Abstract: The clutch assembly employs components (4,6) coupled together with-a friction safety clutch (1), for load-dependent isolation of the power of torque in a drive line. To operate a driven machine briefly, even after the safety clutch has responded, an auxiliary clutch (12) is connected in parallel with the safety clutch. By means of the auxiliary clutch, a reduced torque can be transmitted for a short time so that it is possible to eliminate the cause of the safety clutch having responded and, in the case of a rolling mill, to prevent the mill being shut down. The auxiliary clutch may be either a positive or friction clutch and may be switchable or constantily ready for operation. The actuator is externally and non-rotatably disposed alongside the clutch assembly or integrated into the auxiliary clutch.
