Patent SE-7905682-L (SE)
Inventor: KARLSSON K
IPC: F25B47/02
Filed: 1979-06-28
Abstract: The evaporator (6) of a heat pump or refrigeration circuit is defrosted by use of a switching device 7. The refrigerant by-passes the condenser (4) and the choke valve (5) so that the refrigerant from the compressor (1) flows directly to the evaporator (6) and heats and defrosts the evaporator. Prior to this the refrigerant gas is preferably heat- exchanged with water of e.g. a water heater (3), which water suitably has been heated by the heat pump compressor (1) during its normal duty between defrostings. A small amount (9) of heat exchanged refrigerant gas preferably flows during the defrosting operation to the inlet of the compressor (1) in order to gasify in that inlet liquefied refrigerant, which may be present in the cooled refrigerant gas flowing from the evaporator (6). <IMAGE>

Abstract: Non-fibrillating thermo-weldable films are made from two layers of the same polyolefinic material, following a sequence of operations essentially comprising the extrusion of a base film, cooling and longitudinally stretching it under defined conditions, extruding a relatively thin coating of the same polyolefinic material onto the base film and then transversely stretching the composite film under defined conditions. Typically, an extruded film of isotactic polypropylene is cooled to 40 DEG C., stretched 1:5. coated at a base/ coat ratio of 8:1 and stretched transversely 1:8. The polyolefinic material should be a crystalline alpha-olefine polymer or copolymer or a mixture of such. <IMAGE>

Abstract: 48,345 A spacer and block cutting torch is lowered through the wrapper-to-shell annulus of a removed-top steam generator by addition of vertical sections of hollowback column by vertical movement of a motorized carriage along a rack-and-guide track extending upwardly from atop the wrapper and manipulation of column clamps, one movable with the carriage and the other affixed to the wrapper, to transfer column weight from carriage to wrapper-top during adding and subtracting column sections. The rearward concave side of the column, held flush with the wrapper wall, readily accepts and serves to enclose operating gas hoses for the cutting torch. Yieldable bias means cooperates with the interior of the generator shell to urge the concave side of the column toward the wrapper.

Abstract: An operating arrangement for combined actuation of two movable control devices with the aid of a single operating lever has movement-translating means between an operating device with its associated operating lever and the control devices. The operating device includes a pivot plate (1) centrally mounted by a ball joint for adjustment in any desired inclination in any direction. Two pairs of Bowden operating cables (6, 11) are connected to the pivot plate in mutually right-angular planes. Each pair of cables is connected to a control device (16). In each cable pair one end of the casing (8) of a first cable (6) is connected to a fixed means (9) adjacent the pivot plate, and the wire (7) of said cable (16) is pivotably connected to the pivot plate, while the other end of the casing is connected to the control device, and the wire (7) of said cable (6) is connected to a fixed means adjacent the control device. One end of the casing (13) of the second cable (11) in the pair is connected to a fixed means adjacent the pivot plate and the wire (12) associated with said casing (13) is pivotably connected to the pivot plate while the other end of the casing is connected to a fixed means adjacent the control device and the wire (12) of the cable (11) is connected to the control device. Force transmission from the operating device (20) to the control device (16) always takes place during the development of tensional stress in the wire of the active cable. The arrangement enables the use of relatively light cables, since the wires do not transmit force by means of compression. The light cables enable smaller bending radii and reduced inner friction in the cable for a given bending radius. The light cables permit neater cable positioning to suit the structure on which the operating arrangement is used.

The device for carrying out the procedure is comprised of a transformer (1), that through a current supply device (2) is connected to a frequency converter (6) that is designed to change the power frequency alternating current to an alternating current with a frequency lying between 0.05 and 30Hz. Through the current supply device (2), the frequency converter (6) is connected to electrodes (3) in the device's electric arc furnace (5), in and for supply of the converted current to the electrodes (3). The electrodes (3) are arranged in a vat (4) in the electric arc furnace (5), in which one feeds in the mixed flux material (8) and melts it, at which the melting is followed by oxidation and reduction reactions, by which one obtains a smelt (10) and slag, which are removed from the furnace (4) through a drain opening (11). The device further contains a unit (14) for controlling the frequency converter (6), of which the unit is connected to the current supply device (2) as well as to vents (18, 19) in the converter (6) in and in order to alternately connect and disconnect the vents (18, 19) after an adjustable time interval (δ) between connection and disconnection. The device further contains a unit (12) for regulation of the effect of the electric arc furnace (5), for which the entrances to the unit are connected to the current supply device (2), with the electrodes (3). The unit (12) is additionally designed in order to move the electrodes (3) by way of a mechanism (13) for movement of the same. The invention can be used within metallurgy for iron and non-iron metals, chemical industry as well as for the production of fireproof materials.<IMAGE>

Abstract: In a pneumatic machine for spreading granular material, for example seed or fertilizer, to facilitate testing of the amount of material discharged by the machine, an opening can be caused to appear adjacent the pneumatic ejectors (17) which transport the material to spreading means. The material falls from feeding means (12, 13) into a collecting box (31) placed below the opening, so that the quantity of material discharged can be weighed. When the correct amount of material for a given operation is achieved, the ejector parts (19, 20) are moved to the right by a handle (26), levers (25, 24) and an arm (23) which carries the parts (19, 20). Such movement of the ejector parts closes the opening, after which the machine can be operated for spreading. <IMAGE>

Abstract: This disclosure shows a skating device designed to enable the user to perform the physical movements required when ice skating in artificial conditions, such as, for example, when there is no readily accessible ice rink or frozen lake. As such, the skating device can be used indoors at any time of the year. The device itself consists of a frame with a step for each foot on an approximately horizontal, pivotable guide. Each step is slidingly movable along its pivotable guide. Biasing force means, arising from the use of suitable weights, oppose the skating movements of the user and restore the parts of the skating device to their initial rest positions following these movements. The frame includes a horizontal pole, whose position is adjustable, for gripping by the user's hands.

Rail-shaped mounting elements 4 are first secured on the said insulating material 3 by means of screws or similar securing elements 5 which reach as far as the support 2. The building elements 1 in question are then connected, at any desired position along the said mounting elements 4, directly to the said mounting elements 4 via screws or similar securing elements 10 which reach as far as the mounting element 4.

The screen cloths 14 consist of an elastically stretchable material, for example in the form of perforated rubber cloths. Hinge members 16 between mutually connected chain links 15 are controlled directly or indirectly by wave-shaped guides which extend along at least sections of an upper part of the chains and which, as the chains are advanced, cause their links 15 to execute reciprocating tilting movements, giving reciprocating rotational movements of the cross-pieces 13. In this way, the elastic screen cloths are alternately subjected to stretching and buckling as a consequence of the fact that the distance between the attachment points of the screens alternately increases and decreases upon the said rotation of the cross-pieces. <IMAGE>
