Abstract: A copper extraction process involves the step of treating roasted ore (esp. dead roasted sulphide ore) in an autogenous reduction suspension smelting zone with an oxygen-contg. gas (pref. contg. 50-100 vol.% oxygen) and a reductant in amt. sufficient to reduce the ore to copper. - Blister copper is produced directly from roasted ore, without a converter refining stage, by a continuous, energy-efficient method. Oxidising conditions, required for burning off sulphur and oxidising iron in the ore, can be employed during roasting to give a sulphur dioxide-rich off-gas suitable for feeding to an acid plant, while reducing conditions, required for minimising copper loss in slag, are employed during smelting (cf. flash smelting). The off-gas volume from the smelting operation is much less than that from conventional smelting operations.(0/0)

Abstract: The printed products are fed in an imbricated formation by a transport apparatus to a wind-up station. By opening gripper units of the transport apparatus the printed products are released and drop onto a conveyor belt, the conveying direction of which is opposite to the conveying direction of the transport apparatus. The imbricated formation formed on the conveyor belt passes through a deflector or turning device in which the imbricated formation is deflected or turned by approximately 180 DEG  about the rotational axis of a deflecting drum. The imbricated formation leaving the deflector or turning device is inputted from below to a winding core and wound-up thereon for intermediate storage. For further processing the wound-up imbricated formation is unwound and removed in a direction which is opposite to the wind-up direction. The printed products in the removed imbricated formation have the same relative position as in the arriving imbricated formation with the exception that the top side of the printed products as present in the arriving imbricated formation is now located on the bottom side.

Abstract: A method of feeding cement into a drill hole for cement bolting of a rock, according to which a feeder pipe (2) is pushed into the hole essentially to the bottom of the hole portion to be filled with cement, cement is fed into the hole beginning from the bottom of the hole portion, and the pipe is displaced outwards in the hole when the cement fills the hole. The feeding of cement is stopped and the pipe is removed when the amount of cement is sufficient to fill the gap between the wall of the hole and the rock bolt to be pushed into the hole. The displacement of the pipe is controlled by means of the filling pressure (TP) caused by the cement fed between the pipe tip and the bottom of the hole portion to ensure that the hole is reliably filled despite possible cracks and crushed zones. An apparatus for carrying out the method comprises a feeder pipe provided with a tip of such a size that the penetration of cement through the gap between the hole and the tip requires a pressure which is higher than a predetermined set value of the cement feed pressure and causes an outwards pushing force on the tip.

Abstract: A wheel braking cylinder and an expandable chamber of a pressure modulator are connected in a spatially closed arrangement that is connected to an operator controlled master cylinder, with the chamber being interposed between the braking and master cylinders. When vehicle deceleration reaches an upper threshold, an electromagnet is actuated and the armature thereof operates to isolate the master cylinder from the chamber and expands the chamber to reduce pressure in the braking cylinder, thereby reducing deceleration. When deceleration reaches a lower threshold the electromagnet is de-energized so that force generated by the armature biasing spring acts to reduce the chamber volume, thereby increasing pressure in the braking cylinder.

Date Jun. 16, 1988.A method and device for controlling a bridge circuit for providing current or power to a load. The bridge comprises two transistors including flywheel diodes and connected in series between positive and negative power supply rails for conducting current to or from the load under control of a control drive circuit. An LC-circuit is connected between the bridge circuit and the load. The bridge voltage (E) of the connection between the two transistors and the current (I) through the inductance of the LC-circuit are monitored and a firing pulse is supplied to one of the transistors. When the current (I) through the inductance exceeds a preset value (I'), the transistors is turned OFF, whereupon the current of the inductance continues to flow another way through the flywheel diode of the opposite semiconductor member and consequently the bridge voltage (E) changes polarity a first time to the opposite rail polarity until the magnetic energy of the inductance has been terminated resulting in a second change of polarity of the bridge voltage (E) towards the first rail polarity. The change of the polarity of the bridge voltage (E) towards the first rail polarity is detected and another firing pulse is supplied at or shortly after said change.

Abstract: The invention relates to a device for protecting an integrated circuit against overload and short circuit currents. The integrated circuit functions such that it is alternatively switched to an ON or an OFF state, and when in the ON state a supply current (IM) is amplified by a Darlington - connected transistor step (Q20,Q21) and is supplied to the output (OUT) of the circuit across a load resistor (RLOAD). For an OFF state of the integrated circuit no current is led to the output (OUT). The device in accordance with the invention is a protective circuit (S) comprising a detection resistor (RSENSE) connected in series with said load resistance (RLOAD), a differential step (D) for sensing a voltage (VSENSE) across the detection resistor (RSENSE) and a thyristor (T). Short circuit or overload on the output (OUT) causes an overcurrent to pass through said transistor step (Q20,Q21) and through the detection resistor. The increasing voltage (VSENSE) across the detection resistor due to the overcurrent is sensed by the differential step (D) which thus energises the thyristor (T) so that the supply current (IM) is taken through the thyristor (T) instead of through the transistor step (Q20,Q21). The transistors (Q20,Q21) are thus pinched off, resulting in that the overcurrent is very quickly extinguished. The integrated circuit may be a final step in a semi-conductor relay, for example.

Abstract: This invention concerns a method for radio cell planning. The method utilizes an exclusion matrix calculated on the basis of measured field strengths and an iterative allocation algorithm, which permits an adaptation of the cell planning to suit prevalent traffic requirements. The method comprises the stages: the traffic requirement is estimated geographically; an acceptable coverage of the traffic requirement is achieved using a number of cells with suitable transmission power and antenna arrangement; each cell is allocated a number of channels which corresponds to the estimated traffic requirement taking into account a margin for acceptable blocking; coverage and interference measurements are carried out for the cells, which measurement results are stored in a measurement database; an exclusion matrix is calculated on the basis of the measurement results, which matrix represents the interaction between the cells in the system; an allocation algorithm is iterated, which algorithm gives different configurations of channel allocations to the cells by the utilization of randomization; if the channel allocation is not possible on account of the number of channels in the given frequency band a new attempt is made and the subsequent stages are repeated, if the number of channels was sufficiently large radio cell planning is obtained which is acceptable as regards interference and blocking. <IMAGE>
