Inventor: REEVES JAMES WINDHAM
IPC: G01B21/20
Filed: 1989-11-28
Abstract: To qualify the heights of inwardly projecting nuclear fuel rod-positioning stops formed in the sidewall of tubular ferrules (12) utilized in fuel bundle spacers, an automated gauging apparatus is provided to handle successive ferrules on an automated basis. The apparatus includes an orienting station (32) for longitudinally reorienting each ferrule, if necessary, and angularly orienting each ferrule in a pickup position. A mechanism (68)picks each ferrule from its pickup position and places it on an arbor (84) of a gauging fixture (82) with the rod-positioning stop surfaces bearing against arbor reference surfaces. A plurality of sensors, e.g. eddy current probes, are positioned to measure the proximity of ferrule peripheral surface sites adjacent the stops and thus provide output gauging signals indicative of the heights of the various stops.

Abstract: An electrosurgical generator in an electrosurgical unit (ESU) controls the repetition rate and the energy content of bursts of RF energy delivered to a gas jet supplied by the ESU, in order to maintain RF leakage current within acceptable limits while still achieving a sufficient state of ionization in the gas jet to reliably initiate the conduction of arcs to the tissue. The repetition rate of the RF bursts is substan­tially reduced in an inactive state when no arcs are delivered. A relatively small number of the RF bursts delivered during the inactive state have an increased or boosted energy content to assure an adequate ionization state in the gas jet.

Abstract: Dual-function comb device suitable for shedding and looping, the comb being repassed by the yarn of a warp beam located at a station in the weaving machine, so that a warp-beam/comb connection is obtained. Preferably, the warp-beam/comb connection consists of two warp beams with a comb to be repassed, each connection being transported to the weaving machine where the comb is connected separably to the slay, so that it can be moved to and fro on its shedding path and executes the looping of the fabric during the transition from one shed position to the other. As soon as the yarns of the warp beam are at an end, the comb is switched off, and the warp-beam/comb connection is replaced by another warp-beam/comb connection, and the yarns pass once again to the warping and repassing stations, so as to commence the circuit again.

Abstract: The invention relates to a method and an apparatus for drawing tubular bodies 3, especially rectangular tubular bodies 3 with an arcuate axis 11, as used for moulds in the continuous casting of steel. In the stated applications, and in other applications, compliance with predetermined dimensions for the wall thickness of the tubular body 3 is of great importance. Due to the curvature of the tubular body 3, the rectilinear drive towards a drawing die in the form of a thrust ring 6 leads to an eccentric position during passage through the thrust ring 6, with the result that the wall thickness usually varies. The invention eliminates this problem by virtue of the fact that the thrust ring 6 is moved into an oblique position in a controlled fashion as a function of its distance from the rear end of the mandrel. In this position, the tubular body is guided through the thrust ring 6 in centred fashion, allowing the wall thickness to be kept constant despite differences in the forces acting on the thrust ring 6. A control function for the position of the thrust ring can be established on the basis of empirical measurements of the distance of the mandrel 2 from the inner edge of the thrust ring 6 during the feed motion of the said mandrel. <IMAGE>

Abstract: The present invention relates to a process for selective solution-annealing of the weld zone (2, 3) of a longitudinally welded metal pipe (1). The process is especially suitable for pipes (1) having a diameter of less than 100 mm and a wall thickness of less than 2.5 mm, preferably less than 0.7 mm. In the course of the heat treatment, the weld (2) is first heated under a protective gas (1) to such an extent that its outer region (2.1) is fused. This can preferably be effected by an electric arc (7). Subsequently, the weld (2) is selectively held by further heating means (8), for example further arcs, infrared emitters or induction coils, for a presettable period under a protective gas (I) at least at a temperature (Tmin) required for the solution-annealing of the pipe material, but below the melting temperature (Ts) at least in the inner region (2.2) of the weld (2), and then cooled (10) under a protective gas (I). The single or multiple incipient fusion of the outer region (2.1) of the weld (2) does not reduce the quality of the heat treatment in the inner region (2.2), so that the desired corrosion resistance in the latter does not suffer. However, the partial fusion facilitates rapid introduction of heat for heating up the weld. <IMAGE>

Abstract: A spool (30) for photographic film has a generally cylindrical core (40) with flanges (44) at the end portions of the core. A slot (50) through the core receives an end portion (34) of the film that is to be wound onto the spool. Hooks (60, 62) in the slot are engaged with the film through apertures (36) in the film for attaching of the film to the spool. In order to avoid locking of two spools together during bulk handing, as can occur when a flange of one spool enters the slot of another spool, the outer edge of one wall (46) defining the slot is chamfered (70, 72) and generally V-shaped. The edge of the wall forms a large obtuse angle and is substantially aligned with the tip ends of the hooks so that the chamfered wall and the tip ends prevent a spool flange from becoming locked in the slot of another spool.

Abstract: A floating-point processor for performing an arithmetic operation on two floating point numbers comprises an aligning means (802,803,805,902), a carry save adder-subtracter (102,402,602), a rounding-carry generating circuit (101,401,601), an adder-substracter (103,403,603), an inverting circuit (105) and a selecting means (106,405,605). The carry save adder-substracter generates carry data and sum data, by performing addition or substraction on the two aligned mantissas. The rounding-carry generating circuit generates a first and a second rounding-carry (Cr1,Cr2). The first rounding-carry (Cr1) is generated from a rounding-mode signal, indicating the direction in which a result is rounded and less significant digits of each of the first and second mantissas. Though, in case of overflow, the digit position where the result is rounded may differ by one place, the value of (Cr1) is independent of the digit position where the result is rounded. The adder-substracter outputs a first result (P), which is obtained by adding or substracting the first rounding-carry to the least significant digit position of the carry data and sum data, and outputs a second result (Q), obtained by adding or substracting 1 to/from the first result. 
     The inverting circuit outputs a logical inversion of all digits of the second result. The selecting means selects one of a plurality of results, on the basis of the most significant digits of the first and second results and second rounding-carry. The plurality of results are the first result, the second result and the output of the inverting circuit.
