Title: Pole of an electrical machine
Inventor: KAHLEN HANS DIPL ING DR
IPC: H02K3/32
Filed: 1983-10-06
Abstract: The invention relates to a pole of an electrical machine, especially a DC machine, consisting of a salient pole core (11) and a coil (14) which is wound around the pole core and is supported by insulation. In order to save a coil former and for optimum utilisation of the space around the pole, as well as for good heat conduction between the coil (14) and the pole core (11), it is proposed to wind the coil (14) directly onto the pole core (11), which is covered by a thin, permanently bonded insulating layer (18). The winding space can be optimised by the coil cross-section having a shape other than that of a rectangle. <IMAGE>

Title: Diode circuit for cathodic corrosion protection for steel tubes of high-voltage cables
Inventor: BOETTCHER HEINZ
IPC: C23F13/04
Filed: 1983-11-05
Abstract: The two known reverse-parallel circuits of silicon power diodes (D) for a limiting unit are intended to be provided with the capability to withstand transient overvoltages. This is achieved in the case of a balanced circuit in that the equal number of diodes (D) in the two branches have an equal, sufficiently high peak blocking voltage - in the case of an unbalanced circuit - in that the peak blocking voltage of the individual diodes in the positive branch (PZ) is as large as the sum of the peak blocking voltages of the plurality of diodes in the negative branch (NZ). An application of that balanced circuit is for it to be connected as a potential valve between the steel tube of the cable, which is installed in an insulating manner on a supporting structure in the air, and its earthed supporting structure. <IMAGE>

Title: Method for processing sulphidic copper concentrates and/or copper/zinc concentrates
Inventor: PANCENKO ANATOLIJ IVANOVIC
IPC: C22B19/34
Filed: 1983-11-14
Abstract: For the purpose of processing sulphidic copper concentrates and/or copper/zinc concentrates, these are fused in suspension in the presence of basic fluxes or of a mixture comprising the basic fluxes and the oxygen, to produce a dispersed mixture comprising slag and metallic copper or a white matte. In this process, the said fluxes are fed to the fusion process in quantities which, upon fusion, ensure the production of a highly basic molten slag which is notable for a weight ratio of the amount of silicon dioxide and aluminium oxide to the amount of oxides of calcium, magnesium, iron(III) and iron(II) of 0.01 to 0.33, and for a weight ratio of the amount of calcium oxide and magnesium oxide to the amount of iron(III) and iron(II) oxide from 0.19 to 0.76. The copper oxides and zinc oxides contained in the said molten slag are then reduced with a solid carbon-containing material, which is used in a quantity exceeding the stoichiometric quantity required for the reduction of copper and zinc, until a vapour gas mixture is formed, which contains the vapour of zinc, metallic copper and of the slag low in non-ferrous metals. The said gas/vapour mixture is then reduced until zinc oxides are formed, and the zinc oxides formed are separated.

Title: Driving device for an oil pump
Inventor: LEDNIG LEOPOLD
IPC: F16N13/00
Filed: 1984-04-26
Abstract: A driving device for an oil pump, in particular an oil pump for lubricating a saw chain of a motor-driven chain saw, has a gearwheel and a worm which are arranged on a common axle. The worm is secured axially on the worm. The gearwheel and the worm can be coupled to one another via at least one centrifugal weight designed as a slide, the slide being arranged with the ability for radial movement on the gearwheel and being connected to the latter in a rotationally fixed manner. The slide forms a centrifugally actuated coupling between the gearwheel and the worm, by means of which the worm is automatically separated from the gearwheel in the idling position of the unit. As a result, the worm is halted in the idling position of the unit, with the result that oil is no longer delivered.

Title: Outlet nozzle for centrifuge drums
Inventor: SCHMIDT HANS-HEINRICH DR ING
IPC: B04B1/10
Filed: 1984-07-30
Abstract: The outlet nozzle for centrifuge drums is used for continuously discharging albumen concentrates. The object was to develop a nozzle in which the discharge of concentrate out of the centrifuge drum into the nozzle body takes place over a smaller diameter than the feeding of the concentrate to the nozzle. According to the invention, this was achieved in that the nozzle consists of the nozzle body with a calibrated through-flow opening arranged at an angle to the axis of the nozzle, a mouthpiece and a cap, the cap being of greater dimensions than the mouthpiece and being fitted onto the mouthpiece on the side of the separating space in such a way that annular gaps are formed which can be adjusted as a function of the medium to be processed, and one or more lateral bores are arranged in the cap, the distance of which bores from the axis of the drum being greater than the distance of the end face of the mouthpiece from the axis of the drum and the bores and the annular gaps being selected to be of such a size that their through-flow rate is smaller overall than that of the calibrated through-flow opening (see Fig. 1). <IMAGE>

Patent DE-3502204-A1 (DE)
Inventor: HIENZ GEORG
IPC: H02M5/27
Filed: 1985-01-24
Abstract: A method is described for natural commutation, carried out by the network or load, of a direct converter (DU) between an M-phase network at the frequency F and an m-phase load at the frequency f, especially of an electrical machine. The direct converter (DU) comprises 2 x M x m thyristors, which directionally connect each network phase to each load phase. The method according to the invention is that, in essence, there are always only two thyristors TX,y and Tx,Y which simultaneously carry current from a network phase X to a load phase y and from a load phase x to a network phase Y. In this arrangement, the thyristors are triggered as a function of the phase of the network voltage and of the load voltage. The method allows a continuous change of the load frequency and of the load voltage from zero up to the network frequency or network voltage. <IMAGE>
