Abstract: The chair has a seat (7) provided with a vertically movable part which is returned to its raised position by a resilient leaf spring (10). The spring also senses the weight of a seated person. A backrest support structure (4) is movable relative to a fixed base structure (3) of the chair. The support structure is biased towards a first operative position by a resilient cartridge (23). The load of the cartridge is adjusted automatically in dependence on the user's weight sensed by the spring, this weight acting to aid in moving the support structure to a second operative position.

Abstract: The invention makes known a method for the manufacturing of glass watch dials obtained by processing "murrino" glass, said method comprising a phase for the axial drilling of the "murrina" disc, the hole resulting therefrom having such a diameter as to allow the passage of the watch-hand supporting shaft, and one or more honing phases by means of which the two surfaces of the "murrina" disc become parallel to each other, while the disc itself acquires a thickness which is compatible with the use of the disc as a watch dial, a phase for the trimming of the outer edge of the "murrina" disc and a subsequent phase for the polishing of at least one of the two visible surfaces of the "murrina". Said method allows the manufacturing of watch dials by using "murrinas", i.e. objects constituted by a pluralyty of small glass cylinders melted together and forming phantastic patterns.

Abstract: A method and a device for controlling a brushless alternating current motor (23) driven by an inverter (31-36) connected to a direct current supply (24, 25). The direct current supplied to the inverter is rinsed. The signal is passed through a peak detector (41) to a regulator (45), which decreases its frequency controlling output signal if the peak value input signal exceeds a predetermined value. A control signal corresponding to the torque demand of the motor is also produced. This signal controls the voltage supplied to the motor. Negative pulses at the turning off of the inverter switches are also sensed and used for controlling the degree of magnetization of the motor.

Abstract: The invention refers to a valve device for dividing, regulating and/or reversing of at least one fluid, in which the device contains a housing divided in two comprised of a stationary and a turning housing part in a dividing plane, of which the one is equipped with through holes while the other is divided in a number of chambers separated from each other, of which several are equipped with their own inlets and outlets, at which the one part of the housing is turnable so that the through holes are either each or in a group located in and communicating with the chambers. The purpose is to be able to cause either a heavy vacuum or large amount of air, to be able to turn the vacuum into pressure and vice versa and to reduce the suction or alternatively the pressure and vice versa without the through holes in the system being reduced in size, to create a simply constructed, operationally secure, easily dismantled pressure and suction distributor which through a simple handle can be changed to different function positions. These specifications have been created through the housing parts (11, 12) are designed to, by means of a tension device (13) be pressed so that they lay against each other. The tension device (13) contains a quick lock, preferably an eccentric shackle (31) by which both parts of the housing (11, 12) are arranged in a positioning device (33-35) for exact positioning of the housing parts in different determined relative positions.<IMAGE>

Abstract: Method of conferring load and deformation stability on railway tracks by means of partially prestressed concrete structures, for instance concrete sleepers. The prestressing forces in the tendons during casting and curing may amount to one half of the value for full prestressing. In conjunction with both normal loads and sporadically occurring overloads, the magnitudes of the deformations in the sleepers will be regulated by the stiffness of the sleepers, the modulus of subgrade reaction of the ballast, and the ability of the rails to transmit force. Owing to enhanced deformability of the concrete sleepers in consequence of the reduced prestressing force in the tendons, considerable load energy can be absorbed without the occurrence of permanent damage. The structure as a whole is given such properties that the sleepers exhibit only elastic deformations, and that the cracks which occur in the concrete cross section in tension are completely closed after the load has ceased to act.

Abstract: The object of the invention is a so-called applicator for microwaves 2.45 GHz, to be used in pre-drilled holes in e.g. masonry in order to heat and subsequently dehumidify it. 
<??>The applicator has several radiating areas in the axial direction, eliminating uneven heating which would otherwise result due to the limited microwave energy penetration depth. Furthermore, radiation may be directed in varying angular directions, so that while several parallel holes are being treated simultaneously , drying proceeds preferably in left-right directions thereby improving efficiency. The asymmetrical radiation pattern is emitted from openings in the outer conductor of a coaxial line. In the openings at least one section plane varies in its axial position in relation to the angular coordinate.

Abstract: A method for rapid emptying of refrigerants from large-scale refrigerant and heat pump units. The main components of the invention are a service compressor and a collection tank which may be a refrigerant tube. The collection tank has a liquid connection and a gas connection. The plant which is to be subjected to rapid emptying of refrigerant is assumed to be provided with a refrigerant tank (receiver), with most of the charge accumulated therein. The pressure side of the service compressor is connected to the high pressure side of the plant, ahead of or at the refrigerant tank. The liquid connection of the collection tank is connected after the refrigerant tank. Rapid emptying implies that the service compressor creates the requisite pressure difference between refrigerant tank and collection tank. The service compressor removes by suction the flash gas formed in the collection tank, thus keeping the pressure therein low. The gas quantity compressed by the compressor is now conducted to the free gas volume above the liquid surface of the refrigerant tank. The pressure above the liquid surface thereby increases. This pressure difference entails very rapid emptying of the refrigerant quantity of the system.
