Abstract: ABSTRACT OF THE DISCLOSURE      The invention relates to a method of automatic or remotely operated welding of the cover and/or the bottom to the walls of a container for receiving and storing radioactive fuel elements and wastes in a hot cell by employing the narrow joint welding technique, wherein at least one sensor sensing the course of the weld line between the container wall and the contain? cover and/or bottom is effective to assist at least one three-dimensionally movable welding head controlled by control means utilizing signals supplied by the sensor to guide it along the joint for producing a continuous welding seam consisting of a plurality of super-imposed and offset weld beads or passes, respectively.  To obtain improved welding results and for safe and trouble-free automatic and/or remotely operated welding, the loaded container including the attached cover and/or bottom is caused to rotate about its longitudinal axis, and the joint between contain? wall and cover and/or bottom is caused to move past the sensors and the welding heads.  Upon completion of the welding operation the welding slag is removed.  Sensors are provided for the lateral and vertical guidance of the welding head.  The welding is effected under flux.         A chisel and a nailer are employed to loosen the welding slag which is removed from the weld by a suction nozzle.

Abstract: ABSTRACT     A plastic leaf spring with spring-eyes at the spring-ends has a spring-eye section (1) or a spring-eye body (15, 28) of fiber-reinforced plastic, with the spring-eye section (1) is integrated in the leaf spring body or the spring-eye body (15, 28) is manufactured separately from it. The spring-eye section (1) or spring-eye body (15, 28) contain each a layer (2, 16, 29) of essentially constant thickness with a center section (4, 18, 31) wrapping the spring-eye opening, and two connecting sections (3, 17, 32) appropriately essentially parallel to each other, with the outside surface of the layer (2, 16, 29) forming a hollow groove (13, 24, 33) at at least one transition between the center section (4, 18, 31) and the connecting sections (3, 17, 32).     The strength of the plastic leaf spring according to the invention is substantially increased through appropriately plate-shaped reinforcing elements ( 11, 22, 34) form-locking and/or frictionally connected to each other, which at the outside adjoin the connecting sections (3, 17, 32) under pressure, and of which at least one touches the layer-surface also at a hollow groove (13, 24, 33).

Abstract: Abstract of the Disclosure A belt-type press for making particleboard has a longitudinal row of transverse frames through which pass upper and lower longitudinally extending press beams extending along and carried on the row of frames flanking respective heated press platens in turn flanking stretches of respective upper and lower belts driven to move a mat of particles to be pressed along the path in a transport direction.   The upper beam is pressed down by a plurality of substantially identical hydraulic actuators to compress the mat between the belts with a relatively high pressure in an upstream compression region of the press and with a relatively low pressure in a downstream compression region of the press.  The upper platen and beam have a downstream calibration portion and an upstream compression portion, the latter being elastically deflectable upward relative.  Upper and lower vertically engageable abutments operatively engaged between the upstream portions of the upper platen and beam and the frame limit downward displacement of the upstream portions relative to the frame.          In addition at least one abutment operatively engageable between the downstream portions of the upper beam and platen limits downward displacement of same below a predetermined lower position.  Thus the thickness of the finished workpiece as it exits the press is established by the abutment of the downstream portions.

Abstract: ABSTRACT     A process to eliminate lead in gasoline, at the same time maintaining a high octane number in the gasoline, by irradiating leaded gasoline, containing at least one of ethylene dibromide and ethylene dichloride at room temperature and pressure, with U. V. rays, which generate free organo-metallic radicals which facilitate a photochemical reaction with the gasoline to precipitate insoluble lead halogenates, eliminating "moloxides" responsible for the reduction in the gasoline's octance number.  In this manner an up-graded gasoline is obtained, which is completely lead-free, and prevents atmospheric pollution.

Abstract: ABSTRACT OF THE DISCLOSURE         A width changing method in which the width of a slab under casting is changed by a movement of narrow face of a continuous casting mold by the operation of a horizontal driving device and a rotary driving device operable independently of the horizontal driving device.          The period of width changing operation is divided into a forward taper changing period in which each narrow face is inclined toward the center of the mold and a rearward taper changing period in which each mold wall is inclined away from the center of the mold.  The accelera-tion of the horizontal movement of each narrow face is determined by means of allowable shell deformation resistance as a parameter for each period.  Also is determined the angular velocity of the rotary device or the difference in velocity between the upper and lower ends of the narrow face.  The width changing operation is conducted while maintaining the acceleration and the angular velocity or the velocity difference at constant levels in respective periods.

Abstract: ABSTRACT         There is disclosed a conveyor system in which a main conveyor path is provided with at least one auxiliary path branch-ing off from and returning to the main path past a work station, whereby load carriers moving along the main path under the influence of gravity may be diverted from the main path onto the auxiliary path or paths for processing the workpieces at a work station, in which holding devices determine, from coded information on the carriers, whether individual carriers should proceed along the main path or be diverted onto an auxiliary path for processing at a work station.  An elevator mechanism disposed in the path of the main path at the intersection of the auxiliary path with the main path enables carriers to proceed along the auxiliary path also under the influence of gravity so that carriers diverted onto the auxiliary path proceed also under the influence of gravity from the beginning to the end of the auxiliary path.  The system is particularly susceptible of computer control so that optimum processing at work stations can be achieved.

Abstract: ABSTRACT OF THE DISCLOSURE         A method for function checking microelectronic components inside LSI circuits, particularly during the development phase, provides localization and imaging of regions of a specimen which carry defined signals that depend on the operating status of the circuit.  For localizing the points carrying the defined electrical signals, a primary beam reads the signal at the measuring point and a secondary signal derived therefrom is compared in a detector arrangement to the anticipated or sought-after signal by a correlation method.          For the correlation, the intensity of the primary beam or the current of the secondary particles are modulated alternately with the sought-after or anticipated signal and, respectively, with the negation of the sought-after or anticipated signal and the measured secondary signal is integrated.  Part of the integrated secondary signal changes with the frequency prescribed by the signal change, which is filtered out and supplied to an evaluator circuit which controls the intensity of a display means, such as a picture screen.
