Abstract: A heater mechanism incorporating a thermoelectric converter for use with a self-powered, solid, liquid or gaseous fueled, heater. During operation of the heater mechanism the thermoelectric converter supplies sufficient electrical power to (a) sustain the heater in operation, (b) maintain the starter battery at full charge, and (c) provide auxiliary power to remove and transport heat to desired locations away from the heater. The converter is a highly compact design (high power output per unit volume of space) and lends itself to high volume (mass production) and automated assembly techniques to produce it inexpensively. The thermoelectric converter is made of fewer components than prior art devices. A number of components in the thermoelectric stack serve dual or even multi-functions. The thermoelectric stack components are bonded or mounted together in such a manner as to permit handling as a unit.

Abstract: A plant for the incineration of waste, primarily from retreading shops, with the simultaneous use of the energy content of said waste for steam regeneration to operation and heating. The rubber waste is dosed in an amount dependent on the heat need of the shop with a screw to a grinder where it is ground down into small particles which, mixed with air, are blown into a furnace mounted onto the bottom of a steam boiler. By means of the blowing into the furnace as well as the blowing of flue gas at high temperature in the boiler taking place tangentially, a long period of stay for the burning particles is obtained, thus obtaining a total incineration. The outgoing flue gas is purified prior to release in the usual manner. The furnace is provided with an oil burner, which, in the event of a low energy need in the plant, has sole responsibility for steam regeneration over the oil system and control equipment.

Abstract: A sealing device for a piston of the type which is rigidly connected with the associated piston rod and which is adapted in a reciprocatory motion within an enclosing cylinder to be inclinable a small angle with its longitudinal axis relative the center axis of the cylinder, said piston being intended for use in hydraulic mechanisms, particularly such mechanisms having high hydraulic fluid pressures, is adapted to provide a seal between the cylinder wall and the piston and piston rod assembly and to comprise a plurality of metal sealing rings.

Abstract: Unit for thermal incineration of non-explosive gases with minor amounts of organic pollutants and for production of hot air, and which can be adapted to various types of supplementary fuel. There is a combustion chamber which consists of a flame pipe inside an outer jacket. Through the space therebetween, incoming process gas is led as coolant. At its front end, the combustion chamber has a burner for supplementary fuel and a mixing-in zone for process gas. The process gas rapidly mixes with the hot combustion gases in the flame, the gas reaching its reaction temperature directly. Powerful turbulence in the mixing-in zone gas, film-layer cooling, convective cooling and even flow give highly efficient and pure combustion while keeping the flame pipe temperature low enough to prevent corrosion.

Abstract: A method of producing an object of fiber reinforced metal material, in which method a plurality of fibers or fiber bundles of a material of high strength are arranged at spaced positions, and a matrix material, preferably metal or metal alloy, is brought to closely surround each fiber or fiber bundle and is formed to a shape corresponding to the desired shape of the object. Earlier attempts to produce objects of fiber reinforced metal material have encountered problem regarding the arrangement of the fibers in a uniform pattern and in obtaining a predetermined volume fraction of the fibers in the completed object.
