IPC: B22D27/15
Filed: 1989-04-25
Abstract: The vacuum induction furnace contains a melting chamber (1) with a cooled crucible (2) surrounded by an inductor (3). Accommodated in a crystallising vessel (5) is a casting arrangement (11) consisting of a cooled bottom-pouring plate (8) with a shut-off device (10) for closing and opening an outflow opening (9) in the bottom-pouring plate (8) and of a casting mould (6) situated underneath the outflow opening (9) and intended for the metal, the said parts being connected to one another. The casting arrangement (11) can perform reciprocating vertical movements relative to the crucible (2). The casting arrangement (11) and the crystallising vessel (5) can furthermore perform transverse movements relative to the melting chamber (1), with the result that, on completion of the melting of the metal, the casting arrangement (11) can be replaced rapidly by a new one, prepared in advance. The removal of the casting arrangement (11) with an ingot, the cleaning of the crusts and scrap residues from the bottom-pouring plate (8) are performed outside the melting chamber (1), thereby considerably increasing the output of the furnace. <IMAGE>

Abstract: A hydrofluoric acid/nitric acid mixture with 5 to 12%, preferably 6 to 10%, of hydrofluoric acid and 1 to 5%, preferably 1 to 4%, of nitric acid is suitable for pickling austenitic steels. Spent pickling acid with an iron content controlled at about 35 to 60 g of iron per litre and an n(fluoride)/n(iron) mass ratio of 4 to 6, especially 4.4 to 5.5, is adjusted with alkali to pH 4 to 6, especially 4.5 to 5.5, for reprocessing, a crystalline precipitate (>/= 98% fluoride) being formed. The suspension obtained can be evaporated as such to dryness, but preferably the precipitate is separated from the liquid and disposed of as special waste. The liquid can be concentrated in conventional evaporators without risk of corrosion and dried for harmless disposal as dry material (special waste). Especially caustic soda solution is used for adjusting the pH. The pickling acid is particularly suitable for pickling off radio-actively contaminated steels.

Abstract: The invention relates to a method and a device for sorting material, in particular glass granules or glass containers. A piece of the sorting material is irradiated from one side by light, in particular by white light. It is detected on the opposite side where the light emerges. According to the result of the detection, a fraction of the sorting material is led off separately. It is provided that the light intensity emerging from a piece of sorting material is measured separately for the range of one wavelength, in particularly separately for the ranges of two wavelengths. If two intensities are measured, and their difference is very small, colourless glass is present. Particularly suitable wavelengths are 450 nm and 550 nm. If the difference in the intensities is measurable, coloured glass is present. If, in this case, the intensity can be measured at 450 nm, the glass is green. If, however, the intensity cannot be measured at 450 nm, brown glass is present. A suitable device for carrying out the method provides a light source (4) on an accelerating trough (3) for pieces of sorting material. Arranged opposite the light source (4) is a beam splitter (25) downstream of which are connected a detector (5) for 450 nm and a detector (6) for 550 nm. <IMAGE>

Abstract: The device is intended to measure the temperature reached by the junction of a bipolar transistor operating as a class C amplifier. The variation in the voltage Vbe at constant current i of the amplifier transistor (3) outside the pulses to be amplified is measured with an oscilloscope (16). The constant current i is supplied by a generator (17) and is routed either to the transistor (3) outside the said pulses or to the FET transistor (13) during the said pulses. Since the measurement of the variation of Vbe is proportional to the variation in the temperature of the junction, the temperature reached by the junction can be derived from it.

Abstract: In a fork lift vehicle (10) that includes an extensible boom (14) pivoted at one end to a base (12) and carrying a fork platform (18) at the opposing end, fork height above a horizontal plane that intersect the boom/base pivot axis is determined upon initiation of an automatic mode of operation. A pair of sensors (44) provide associated signals as functions of boom extension and boom angle respectively. Boom extension is directly controlled by the vehicle operator during the automatic mode of operation, while boom angle is controlled as a combined function of the angle and extension sensor output signals (R3,A3), and desired platform height above horizontal. Thus, velocity of motion at the boom end platform remains directly controlled by the vehicle operator while verticle height of the platform forks is maintained.
