In accordance with the invention, partly the cooling effect of the material on a measuring body (1, 35, 41, 50), performing in the material, at a temperature above the boiling point of the liquid, is recorded, the material and the measuring body moving in relation to each other, and partly the cooling effect of the material on a measuring body (2), performing in the material, at a temperature below the boiling point of the liquid, is recorded. The comparison between the two recordings results in a relation, which gives a measure as to the moisture content.

Abstract: Quartz crucibles (710) as illustrated in Fig. 8 for the melting of silicon and ceramic substrates are coated with protective materials (710') or metals at least in part evaporated from an electrode (701,702) with which an arc is struck at low voltage and current to deposit material from the electrode (701 or 702) on the substrate in a vacuum chamber. The electrode (701,702) may be heated and the substrate (710) may be sandblasted and preheated. Specifically a method of coating a quartz crucible for use in the melting of silicon comprises the steps of juxtaposing a pair of electrodes, composed of at least one component of a material adapted to coat said crucible, with an interior surface of said crucible; evacuating the space in which said electrodes are juxtaposed with said surface and maintaining a fixed pressure during deposition; and striking an electrical arc between said electrodes at one end of each of said electrodes at a voltage in the range 30-60 volts and with a current in the range 50-90 amperes by intermittently bringing said electrodes into contact with one another and separating them, thereby depositing material evaporated from said electrodes substantially over said interior surface of said crucible. <IMAGE>

Abstract: A method of subjecting a welded structure to heat treatment in which a tensile yield is produced on an inner surface of the welded structure and a compressive yield is produced on an outer surface of the welded structure by the steps of placing a cooling medium in the interior of the welded structure and heating the outer surface of the welded structure to cause a difference in temperature to exist between the inner surface and other surface of the welded structure. The method further includes the step of locally heating a weld by means of a heating member to improve residual stress in a localized area of the weld and repeating the improvement of the residual stress regarding another localized area of the weld.

Abstract: Melt treatment involves forming a flow of low-temperature plasma by passing plasma forming agent through the arc and introducing the low temperature plasma stream to the metal melt. The plasma stream should be introduced into the melt from within this, from the meniscus side at a rate of up to 1500 m/sec so as to mix the melt, feeding in additives previously led through the plasma stream. The additives preferably contain nitrogen and comprise slagging fillers crushed beforehand to 0.1 to 1.0mm and with 0 to 100% oxygen content relative the plasma forming agent volume. - Equipment includes a plasmatron reciprocating in the vertical over the melt meniscus. The plasmatron should be fitted with a nozzle connected to the plasmatron endface directed toward the melt. The inlet section of the nozzle should equal the plasmatron outlet section at the plasma stream exit and the nozzle should be immersed in the melt to a length between 0.1 and 0.8 of the height of the column of melt. Preferably the plasmatron can adjust in the horizontal plane and is in jet design, with external plasMa arc. At its outlet the nozzle should be fitted with a plate whose centre hole coincides with the inside nozzle bore, and whose continuous vertical channels increase in number from the centre outwards. The nozzle should also have an additives feed orifice at the outlet.

Abstract: Device/devices at clocks of common well known looks, where the figures (symbols) on the clockface can be repeated in a dislocated position. At private and public parties, where a consumption of alcohol takes place, it can be desireable to hint, in a humorous way, a limitation of the consumption or, for example closing time. Double-sight on a clock would be very strongly noticed. A fixed opaque clockface 6, has a movable transparent clockface 9 with identical figures, in front which can be moved manually mechanically or electrically, to shift the transparent clock-face from a starting position, where the figures on the two clockfaces are superimposed 17, to positions where these figures are relatively displaced to give an impression of double-sight to the eye.

Abstract: The magnet ignition system (1,2,3) is arranged to generator current to an electrical component (4) for control of fuel flow through the carburettor fuel mouthpiece. The electrical component consists of a heat unit, such as an electrical spiral (4), built into an airtight closed bellows which is coupled to an adjustment needle to the fuel mouthpiece. By heating the air in the bellows the latter extends and in turn activates the adjustment needle to alter the fuel flow through the mouthpiece. The bellows serves as thermic insulation against the carburettor body. The bellows varies its size with the alteration of the atmospheric air pressure and/or temp. and/or humidity, thus ensuring that the adjustment needle mechanical basic position is correct at each atmospheric condition.

Abstract: A semiconductor device (JFET, 4, 5) is supported by a semiconductor body which comprises a substrate (1), an oxide layer (2) and a weakly negatively doped (n) monocrystalline wafer (3). Trenches for a dielectrically isolating layer (5) which surrounds a component region (4) are etched in the wafer (3). A field effect transistor (JFET) in the component region has two positively doped (p) wafer-like gate regions (G1), which have been diffused in the component region with the aid of a first mask. Two heavily negatively (n<+>) doped regions (S2, D2) are diffused in the component region with the aid of a second mask, these regions forming the source region and the drain region of the transistor (JFET). The semiconductor body (1, 2, 3) is easy to produce and is available commercially, which simplifies manufacture of the field effect transistor (JFET). Manufacture is also simplified because the configuration of both the component region (4) and the parts (G1, S2, D2) of the transistor (JFET) are determined by the simple choice of masks. The component region (4) is weakly doped (n) and is easy to deplete of charge carriers. The electrical field strength in the component region (4) is weak, according to the RESURF method, and the field effect transistor (JFET) with-stands high voltages (VS, VD, VG) without risk of current breakthrough. The component region (4) occupies only a relatively small area on the substrate (1). <IMAGE>
