Abstract: The invention concerns a process for assembly of the end of a girder (16,18',18",20', 20"and the associated region of a crossbrace (10,12), constituting components of the chassis end of a railway vehicle, with the girder and crossbrace each comprising at least one vertical web and upper and lower flanges. According to the invention, the flanges of the girder are cut away such that its web extends longitudinally beyong the edges of the flanges. Then the flanges of the crossbrace are cut so as to form attachment journals with free edges adapted to the respective free edges of the flanges of the girder, at the same time, forming in the region of the free edges, hook-shaped lateral appendages. The crossbrace and girder are positioned so that the respective free edges of the flanges of the crossbrace and the girder essentially abut one another, and the girder and crossbrace are welded together in the regions of mutual contact.

Abstract: An automatic method of and apparatus for taking up slack or relieving undue tension in a closed loop chain conveyor traveling in a corresponding track loop by dividing the track into separate sections, sensing the elongation or contraction in the chain in one section, and responding to such sensing to move the other track section away from or toward the said one track section to compensate for the chain length variation.

Abstract: A mechanism for anti-seismic connection between the pump base and the dome of a nuclear power station is characterized by the fact that the pump base (1) is equipped externally with a flange (3) seated with a slight axial play and significant radial play within a socket (4) which is a fixed cover closed by and able to slide axially with a slight play within a cylindrical reinforcement (7a) of the dome (7). A radial damping mechanism (8) is installed between the flange (3) and the socket (4) to permit slow displacements between these two entities, but to block abrupt displacements. The lower end of the socket (4) comprises a collar (15) equipped with a metallic journal (16) which can slide axially within a bearing (17) firm with the internal wall of the dome (7).

Abstract: The present invention concerns a process and a circuit enabling determination of the last intermediate node of a pathway comprising a minimum number of nodes from the m-th node to the n-th node in a network comprising p nodes interconnected by a number of links (p being a positive whole number). The process includes steps of iterative matrix calculation and comparison of elements of the same rank of certain matrices, and is especially suitable for communications networks constituted by a number of geographically separated nodes connected to one another by communications lines.

Abstract: The invention concerns a process for control of the opening of a power interrupter, especially a transistor, at a determined instant, regardless of the particular characteristics of the interrupter. According to the invention, the emission of the normal closing command (A) of the interrupter is terminated at a determined time interval before the said determined instant, and in its place is emitted an additional closing command (G) with a duration equal to the difference between the said interval and the actual time required by the interrupter to pass from the closed state to the open state. Preferably, the actual time required by the interrupter to change state is determined during its preceding passages from the closed state to the open state.

Abstract: Method and apparatus of obviating cycle-locking slippage errors in reception of Loran-C and similar radio-frequency signals covered by receiver location acceleration effects and other distortion effects simulating the same, that comprises, receiving the radio-frequency signals and producing data by sampling and tracking the cycles of the signal with a time-constant filter sufficiently fast to accommodate for the largest acceleration to be experienced by the receiver location to avoid cycle slippage in locating a predetermined cycle zero crossing, and independently post-filtering sufficiently slowly to smooth the data and without interaction with said sampling.

Abstract: An automatic gripper, useful especially for gripping and holding drilling rods on a drilling rig, has a chassis with a front end in the form of a fork equipped with retractable jaws (50). The jaws are retracted by pushing contact with a drilling rod (40) when the rod enters the fork, whereupon a return mechanism (72) automatically restores the jaws to a closed position. The chassis is held fixed on a horizontal pivot axis by rupturable pins or the like. The pins rupture to permit the chassis to pivot when subjected to a predetermined torque, with friction members being provided to frictionally limit the pivotal movement of the chassis. The gripper is thus protected against damage from impacts with the rod lifting mechanism of the drilling rig, for example.
