Abstract: A cylinder block (1) has radial bores (3) of rectangular cross section with a piston comprising a hollow roller (5) and a piston cap (4). The rollers (5) are supported on an outer cam (2). The piston caps (4) are periodically exposed to the pressure (p) of a medium which is delivered to them via channels (11, 13) in side sealing plates (6,7) and via the hollow spaces (10) of the rollers (5). The piston caps (4) are provided with sealing strips (17, 18) resting on bore walls (8, 9) and with support ribs (19, 20). Each roller (5), with the two associated bore walls (8, 9), forms gaps each of which, together with the one sealing strip (17, 18) and bore wall (8, 9) define an intermediate chamber (pc, po). From the intermediate chambers (pc, po) channels (25, 26) lead in the piston cap (4) to the support faces ( 23, 24) of the support ribs (19, 20). The support face (23) lifting away during operation at a predetermined inclination of the cam (2) places the intermediate chamber with which it communicates under an intermediate pressure (pc) determined by the pertinent gap (hc) of the roller (5) and the bore wall (8), this intermediate pressure (pc) forcing a speed upon the cylinder block (1). The oppositely located intermediate chamber having low pressure (po) is sealed off from the pressure (p) of the medium by the support face (24) of the other support rib (20) resting on the other bore wall (9). As a result, it is possible to reduce unavoidable leakage losses without impairing the mechanical efficiency of the unit.

Abstract: The invention relates to a method for producing blister copper from copper-iron sulphide concentrates, and particularly from concentrates whose sulphur content is insufficient to effect autogenous smelting of the concentrates to matte. The invention is characterized in that the concentrate, together with slag former, is smelted with oxygen-gas or air rich in oxygen in a top blown rotary converter, to form a mixture of a contaminated copper metal phase, magnetite and fayalite slag, whereafter a reductant, preferably coke, is supplied for the reduction of magnetite while supplying heat. After the reduction process, the slag is separated from the formed copper metal phase, which is then refined to blister copper in a manner known per se. In this respect, a preferred method of refining the copper metal phase, or black copper, is to refine the black copper, subsequent to separating the slag, in the converter by an oxidizing process with the addition of a further slag former, to form blister copper and a slag containing oxidized impurities from the ingoing copper metal phase.

Abstract: The present invention relates to an optical sensor (1) used to determine the position of an object. A convex reflecting edge (8,9) is arranged in the radiation path between a radiation emitting element (3) and a radiation detecting element (4). The use of a convex reflecting edge (8, 9) involves a more accurate determining of a position of an object than determining according to prior art sensors using a flat inclined reflector. The convex shape of the reflector accordingly eliminates the need of additional slots. The mounting of the respective components of the sensor is not critical either, because it is easy to find a reflecting area of the reflector which reflects the radiation towards the radiation detecting element (4). The sensor (1) is suitable for use in printers and similar equipment for sensing of documents (10).

Abstract: The present invention provides a process for separating a concentrate containing two or more minerals having substantially similar paramagnetic properties by treating the minerals particles with a dispersing agent so as to maintain the particles adequately dispersed during a subsequent magnetic separation step. Thus, in one embodiment of the present invention a method is provided for separating sulfide concentrate into at least two fractions. The process comprises obtaining a slurry of the sulfide minerals particles, adding a dispersing agent to the slurry so as to maintain the particles in the slurry dispersed during a subsequent magnetic separation step and thereafter passing the so dispersed particle slurry to a high gradient magnetic field whereby the more magnetic particles are retained within the field and the less magnetic particles pass therethrough thereby affecting separation.

Abstract: The invention relates to a device for the triggering of ignition sequences in internal combustion engines with capacitor discharge ignition. The device has two trigger circuits (19, 14, 15 and 10, 16, 17) containing differently timed and/or phased signal sources, which circuits comprise windings (9 and 10) fitted on separate limbs of a ferromagnetic core. Under the effect of the magnetic poles (2 and 3) present in a flywheel trigger signals, variable with the engine speed, are induced in the windings. The succeeding trigger circuit (10, 16, 17) is equipped with a trigger signal-deriving circuit (31, 32, 35, 36), controlled by the trigger circuit (1, 14, 15) first influenced, which circuit (31, 32, 33, 36), after triggering, derives the residual trigger signal energy generated by the said succeeding trigger circuit (10, 16, 17). This prevents the trigger voltage from exerting an influence on the succeeding capacitor charging sequence. The invention also relates to an engine speed limiting circuit, in which the said residual trigger signal energy is used to prevent exceeding of a maximum speed by influencing the capacitor charging sequence. <IMAGE>

Abstract: The invention relates to an electronic power drive for centrifugal separators, preferably for relatively large powers, in which the motor is flanged directly onto the spindle of the centrifugal separator. The object of the invention consists in ensuring an optimum speed of revolution which can be adjusted during the start-up phase, operating phase and slowing-down phase by the direct drive of the separator spindle and, by using series motors, to keep the operating costs and manufacturing costs low, accompanied by optimum mass/power behaviour.   According to the invention, this is achieved in that the drive, the control and regulating of a standard-design induction motor, preferably a three-phase squirrel-cage motor is carried out by means of a known frequency convertor, consisting of an uncontrolled three-phase bridge and a multi-pulsed three-phase power inverter which is built up with thyristors and operates in a computer-supported manner and the corresponding speed of revolution of the separator is set by means of the frequency convertor as a function of the process parameters.

Abstract: The invention concerns a combination mast for carrying at least two different pieces of equipment, for example a TV aerial and a solar cell panel or a conventional TV aerial and a parabolic aerial. The mast is primarily intended for use in caravans, campers and the like. A mast according to the invention has advantages concerning simplicity of setting and aligning the various pieces of equipment and aerials and also concerning installation which due to the reduced need to make holes thereby reduces the risk of leaks. A mast according to the invention comprises three concentric tubes placed one inside the other. The outer of these is fixed permanently while the two inner longer tubes are movable so that they can be extended in length and also turned around their longitudinal axis. On the upper part of the outer tube there is a principally horizontal arm. On this there is a movable fixing to support a piece of equipment in such a way that it can pivot, which is also attached to the middle tube in such a way that it can pivot. If the equipment consists, for example, of a parabolic aerial or a solar cell panel, this can be turned through 360 degrees around the axis of the tube and can also be set at a suitable inclination to the vertical. Leads and cables from the equipment mounted on the mast are taken through the mast in the space between the tubes. <IMAGE>
