Abstract: An improved process for removing dissolved metals from waste water using a recycle high density sludge is described. Specifically, the process comprises the steps of: (1) treating waste water containing dissolved metals with a recycle stream containing alkaline surface active recycle particles to precipitate the dissolved metals on the surface of the recycle particles; (2) treating a portion of the treated waste water containing metal precipitate solids with an alkaline reagent to form alkaline surface active recycle particles; (3) recycling the alkaline treated stream containing the alkaline surface active particles; and (4) separating the portion of the stream from step (1) not treated with alkaline reagent into a water component which is free of dissolved metals and solids and a sludge component which contains solids. The improved process is further enhanced by using a solids classification step to preferentially separate finer metal precipitate particles, which are treated with an alkaline reagent and recycled, from larger metal precipitate particles, which are discarded.

Abstract: In an apparatus for cutting thin planks (22) from squared timber (6) which is moved on a guide face (4) against the cutting edge (16) of a knife (14), the adjustment of the distance between the guide face (4) and the plane (24) parallel to the latter and running through the knife cutting edge (16), and hence the setting of the apparatus to different plank thicknesses to be produced is performed by relative adjustment of the knife cutting edge (16) with respect to the guide face (4) in an inclined plane (36) forming an acute adjustment angle ( alpha ) with a normal (32) to the guide face (4). As a result of this arrangement, the distance between the knife cutting edge (16) and a counterpressure edge (30) is automatically adapted in the cutting direction if the plank-thickness setting of the apparatus is altered. Furthermore, in a preferred embodiment it is possible with this one adjustment also for the width of the discharge channel (between the faces 26 and 50) for the cut plank (22) to be simultaneously set to the new thickness. <IMAGE>

Abstract: There is a method of screw-fastening of a drilled-through flat part (7) to a profile carrier 1, in which the profile carrier 1 is provided with a grooved channel 2 which is bounded by two channel walls 4, and in which an attachment screw 9 projects into the grooved channel 2, the shank 11 being screwed into the grooved channel 2 by means of the thread 12, and held. In this case, it is desired for the device to be less costly and to be assembled in a simplified manner. This is achieved in that the channel walls 4 pass through free from any projection as far as the outside 3 of the profile carrier 1, in that their distance from one another is matched to the thickness of the shank 11, and in that the attachment screw is constructed as a sheet-metal self-tapping screw 9 whose thread 12 engages in the channel walls 4. The channel walls take over the function of a mating piece for the sheet-metal self-tapping screw. <IMAGE>

Abstract: The driving device (1) comprises a drive spindle (5) with a spindle thread (8) and at least one carrier member (17). The latter is connected to a brewing cylinder (9) of a brewing unit (2). The carrier member (17) has partial thread turns on the side facing the spindle thread (8) which engage with the spindle thread (8). Due to the fact that the carrier member only partially encloses the peripheral circumference of the drive spindle (5), a plurality of brewing units (2, 2') can be arranged distributed evenly around the circumference of the drive spindle (5) and be driven jointly by the latter. A further advantage of the carrier member designed in this manner consists in the fact that it can be produced in a simple manner by injection moulding. The drive device according to the invention is of very simple construction and is insensitive to soiling. The connection of the drive spindle (5) to the carrier members (17, 17') is self-cleaning. <IMAGE>

Abstract: The invention relates to a process and apparatus for thermal surface treatment of wire rods with a metallic surface by means of an electric arc which rotates, magnetically driven, about the axis of the billet, the arc moving between an annular electrode (anode) and a billet taken through the latter and serving as cathode. According to the invention, the problem of developing improved measures for stabilizing the arc is solved, inter alia, in such a way that the rotation of the arc is achieved by means of a direct-current magnet arranged downstream of the annular electrode in the direction of running of the billet and, at the same time, the magnetic field induced by the direct-current magnet counteracts the effect of the arc root being taken along by the moving billet, and that the annular electrode current is divided into two part currents. The field of application is predominantly the thermal surface treatment of wire rod materials with a metallic surface.

Abstract: The invention relates to a method for producing printed circuit boards with through-plated holes and very small solder lands, or no solder lands, around the through-plated holes. During the production of such printed circuit boards, especially in accordance with the Tenting method, there is a risk of the photographic film tearing off and etching medium penetrating into the metallised holes and damaging the metal sheathing. This can be avoided by producing a protective coating before the photographic film is applied. The invention is based on the aim of specifying a method in the case of which the advantages of the Tenting method can be maintained, but without a photographic film being used. This is achieved in that the printed circuit board (1) and the metallised holes (3) are provided with a protective film (4) which is resistant to alkaline etching medium but is soluble in acid. The protective film is then mechanically removed from the printed circuit board surface, and the printed circuit board is coated with photoresist (8). After coating and development of the photoresist (8), etching is carried out using an alkaline etching medium, and the photoresist coating (8) and the protective film (4) in the holes (3) are then removed by means of acid. <IMAGE>

The current supply to the first capacitor (14) is temporarily interrupted by the interrupting means (48) at least during part of the discharge period. The second capacitor (30) operates as an auxiliary capacitor in which the charge is stored which would otherwise have been supplied to the first capacitor (14). After the interrupt period the charge stored in the second capacitor (30) is supplied back to the first capacitor (14) by the supply means (50). In this manner there is achieved that substantially no charge current is lost during a total period of time of a charge and discharge cycle. In the total period of time the whole charge current of the current source ends up in the first capacitor, so that tolerances in the discharge period no longer affect the oscillation frequency of the sawtooth oscillator. <IMAGE>
