Abstract: The present invention relates to a method for purifying silica waste obtained in the manufacture of aluminium fluoride from hexafluosilicic acid and aluminium hydroxide, whereby the silica, is subjected to an acidic leaching at a pH below 3 to leach out part of the fluorine and substantially all the aluminium present in said waste, and is thereafter subjected to an alkaline leaching at pH 8.5-11.5 to leach out remaining fluorine present in said waste. The teachings are preferably carried out at elevated temperatures, normally 60-90°C, and for a time sufficient to considerably reduce the contents of aluminium and fluorine, normally 1-3 hrs.The silica obtained is highly reactive and can be used as such or transformed into sodium slicate by a reaction with sodium hydroxide. The contents of fluorine and aluminium can be transferred to a process for the production of cryolite or similar compounds.

Abstract: The invention relates to a speed control mechanism especially for internal combustion engines, which are provided with carburettors, comprising a control element connected to the engine in question - a manually operatable mechanism arranged at a predetermined distance from the control element and a connecting arrangement allowing an adjustment of the manual operating mechanism to be proportionally transmitted to the operating element. According to the invention the control element is connected to a contact breaker switch (8), which is electrically arranged inside the electric circuit for operation of the engine. This contact breaker switch (8) also has a spring loaded, displaceable contact element (11), which by means of a tension element (5) held under tensile stress is held in a position in which the electric circuit is closed. As soon as a certain play occurs on the relevant tension element (5), however, the electric circuit is opened under the influence of the said spring. In this way an engine can be automatically shut down if the control element jams in a certain throttle position, for example due to freezing. <IMAGE>

The wet electrostatic precipitator (1) includes a condensing cooling arrangement (21) which is integrated with the precipitator unit (20) of the electrostatic precipitator. A plurality of emission electrodes (4) are located within the collector electrodes (5) and the collector electrodes extend through the cooling arrangement (21). Means in the form of distribution pipes (50, 60) are disposed in the upper and lower end-parts of the precipitator unit (20), in a manner such as to achieve uniform distribution of cooling medium (23) on the outer surfaces of the collector electrodes (5), the gas flowing forwardly within the collector electrodes (5). This uniform distribution of cooling medium results in a reduction in the rate of corrosion on the inner surfaces of the collector electrodes (5), as a result of the formation of condensation on these surfaces and as a result of the uniform and low temperature of the collector electrodes and also as a result of a lower concentration of corrosive substances in the condensate. This affords both technical and economical advantages and also enables the collector electrodes to be made of steel which has a relative low alloy content.

Abstract: In a packet network for electronic transfer of data packets from one end station to another end station, there are, in the conventional way, a number of switch units. Each end station is connected to a switch unit, and the switch units perform the transfer of data packets along an established connection. The switch units are provided with switch ports on all of their connections. In these switch ports, a substitution is performed of labels of the data packets, both for data packets arriving to the switch unit and for data packets forwarded from the switch unit. The substitution prevents data packets belonging to different connections from having the same label and also offers distributed services in the data network. The data packet labels are constructed of a VPI field and a VCI field and, for data packets that arrive directly from or are sent directly to an end station, a GFC-field. In the substitution of the label of a data packet arriving to a switch unit, a table look-up is first performed in the associated switch port by way of the contents of the VPI field of the data packet. The result of the table look-up gives a direct information if the data packet belongs to a connection having a label comprising only a VPI field (VP connection), and then its contents are replaced by a record obtained in the table look-up. If the data packet has both a VPI field and a VCI field (VC connection), its VPI and VCI fields are replaced by new label portions obtained from a second table look-up.
