Abstract: A press for the hydrostatic extrusion of long billets has a stand with a pressure generating chamber and a pressure generating plunger insertable in the pressure generating chamber to generate high pressure in a pressure medium contained therein. A pressure chamber is arranged in line and communicates with the pressure generating chamber. A stationary support table is provided to take up axial forces on a die, and is spaced from the opening of the pressure chamber so that a die can be inserted into alignment with the opening of the pressure chamber. The support table contains a piston which is movable in the direction of the pressure chamber and on which the die support is carried for movement of the die into the opening of the pressure chamber opening.

Abstract: Disclosed herein is a current control system for a static converter. The converter has an inductive load object connected to its DC terminals and has a plurality of controllable rectifiers with a firing pulse generator connected to the rectifiers for supplying firing pulses thereto in a predetermined commutation sequence. The control system has a current sensing device for sensing the DC load current of the converter. A function generator computes, on the basis of this current, during each interval between consecutive firing pulses, a predicted load current value. This predicted value at each moment during one of said intervals corresponds to the load current, which is obtained during the next one of said intervals, if the next firing pulse in the commutation sequence is supplied at that moment. The predicted value is compared with a current reference value. When these two quantitites become equal the next firing pulse is supplied.

Abstract: A converter connection for improving the symmetry of a threephase network comprises a three-phase line-commutated controlled converter which has its AC terminals connected to the network and its DC terminals to a reactor. Firing pulses are supplied to the rectifiers of the three rectifier groups of the converter, each of which comprises the two rectifiers connected to one of the three phase conductors of the network to fire the two rectifiers of each group at a fixed 180* interval. The phase angle in relation to the AC network voltage of the firing pulses is individually controlled for each of the three groups in dependence upon the deviation of the AC voltage of a point in the network from a reference level, the reference levels of the three groups being substantially equal.

Abstract: FOR MANUFACTURING BILLETS OUT OF POWDER FOR FURTHER MACHINING BY ROLLING, FORGING OR MCAHINING, POWER IS POURED INTO A CONTAINER HAVING AN EVAUCATING OPENING AND IS THEN ISOSTATICALLY COMPRESSED BY SUBJECTING THE CONTAINER WITH THE ENCLOSED POWER TO A HIGH EXTREME PRESSURE. THE BILLET IS PLACED IN A HEATED FURNACE AND HEATED WHILE IT IS SIMULTANEOUSLY EVACUATED FOR DEGASSING. AFTER EVACUATION IS COMPLETED, THE BILLET IS PREHEATED IN ANOTHER FURNACE TO A TEMPERATURE SUITABLE FOR PRESSURE SINTERING AND THEN IN ANOTHER FURNACE IS SUBJECTED SIMULTANEOUSLY TO HIGH HEAT AND HIGH PRESSURE.

Abstract: A crane includes two gripping members or spreaders mounted adjacent to each other for raising and lowering movement by cables and for horizontal movement between a dock and a ship having compartments for receiving loads. The gripping members are provided with a magnetic or similar arrangement by which they can be coupled together or de-coupled from each other. The upward and downward movement of the gripping members when they are above the ship compartments is controlled by a memory device. During upward movement, when the gripping members reach a certain position when they are outside the compartments (cell construction) the magnetic or similar arrangement is energized and the gripping devices (spreaders) are coupled together. Thereafter the gripping devices are moved away for loading or unloading purposes. This upward movement is stored in the memory device to a certain point. When the loaded gripping members are moved downward, the memory device causes them to be uncoupled at a certain distance above the compartments and thereafter to stop within the compartments at substantially the same level from which they had previously started. The arrangement may also be such that the gripping devices can start at different levels, will move to the same level, be thereby coupled together, and on the downward movement will each stop at substantially the same position from which it started previously. This requires the use of one, preferably two memory devices, one for each gripping member.

Abstract: A coil having several turns of an insulated conductor is provided with a shrinkage tube of insulating material by producing such relative movement between the conductor and the tube that the end of the conductor passes into the tube and through it a number of times until a portion of all the coil turns is enclosed within the tube. The tube, which may be corrugated to shorten its length during the winding operation, is then heated beginning at one end and expands along and contracts over the wound coil.

Abstract: In a fuel assembly for insertion from above into a nuclear reactor core a fuel rod bundle is arranged as a freely moveable loose insert in a weight carrying square sheathing tube, which has at its upper end connection members such as two diametrically opposed lifting lugs permitting a grab member in a lifting device to grab the sheathing tube for lifting the entire fuel assembly. The upper part of the sheathing tube is formed as it springs supporting the fuel assembly laterally against an upper core grid and supporting the fuel rod bundle laterally against the sheathing tube wall.

Abstract: For testing electrical equipment, a test rig is provided with a number of contact boxes mounted in a frame. Each box contains a normally closed pair of contacts which are connected to apparatus to be tested. A test handle is provided with a number of pins adapted to be connected to testing equipment. The test pins can be inserted through openings in the front of the boxes to enter between the contacts, thus separating them and making a connection to the testing mechanism. An arrangement may also be provided by which the contacts of adjacent boxes can be connected to each other by the opening of the contacts.
