Abstract: In a multi-point method of determining a human time-zero blood volume a radioactive tracer is injected into the blood stream, and a plurality of mixed samples of blood and tracer are removed from the blood stream at a corresponding plurality of measured time intervals subsequent to the injecting step; a blood portion volume corresponding to each time interval is automatically determined from the diluted tracer level in the mixed samples, and a time-zero blood portion volume is auto­matically calculated from the determined blood portion volumes and time intervals. 
     An analyzer for the method includes a sample holder for receiving the samples, means for automatically determining from levels of the tracer in the mixed samples a blood portion volume corresponding to each time inter­val, and means for automatically calculating therefrom the time-zero blood portion volume. 
     The invention is useful prior to surgery or blood transfusion.

Abstract: Off-gas (3) generated when spent fuel (1) containing radioactive iodine is subjected to shearing and dissolving treatments (2) is scrubbed (4, 5) and, when necessary, subjected to a precipitation treatment (8) by addition of additives, after which waste liquid containing radioactive iodine is freeze-dried (9) by a freeze vacuum drying process to recover radioactive iodine as iodine compounds (10, 11). Since the radioactive iodine does not vaporize, release of the radioactive iodine into the environment can be eliminated; also, consump­tion of a collecting agent such as silver zeolite for collecting vaporized radioactive iodine can be reduced. 
     The iodine compounds containing the recovered radioactive iodine are given the same composition as a stable, naturally occurring mineral and solidi­fied and mineralized (13, 14) as by a high-pressure press. This makes it possible to store long half-life ¹²⁹I radioactive iodine safely for an extended period by sealing recovered radioactive iodine in a stable mineral.

Abstract: Une pompe de cryosorption régénérable (10) possède une barrière physique mobile (32) laquelle comprend un corps cylindrique fermé à une extrémité (33) et doté d'une chicane circonférentielle (34) autour de l'extrémité ouverte (35). La chicane (34) s'engage dans une bride (36) de la surface (20) de pompage et de condensation des isotopes hydrogènes pour que tous les gaz entrant dans la pompe (10) pendant le fonctionnement normal passent au travers de la surface (20) de pompage et de condensation des isotopes d'hydrogène, évitant ainsi de bypasser cette surface (20). La barrière (32) peut avancer à l'aide d'un système à soufflet (38) pour isoler la surface (20) de pompage et de condensation des isotopes d'hydrogène par rapport à la surface de sorption (28) pendant la régénération, ce qui provoque la séparation des isotopes d'hydrogène, par exemple le tritium de l'hélium dont la sorption s'effectue sur la surface de sorption (28).

Abstract: Ce dispositif comporte, sur un cadre de base mobile (1), deux cadres de levage (5/6) supportant une plate-forme (4) servant à recevoir le bogie à changer; la hauteur de ces deux cadres de levage peut être réglée séparément par des organes de levage (2/3). Un des cadres de levage (6) peut être relié avec la plate-forme (4) de manière à se déplacer avec elle via des piliers (7) qui peuvent passer d'une position opérationnelle à une position inactivée, ce qui permet un mouvement de levage au-delà de l'autre cadre de levage (5). Le cadre de base (1) comporte un dispositif (10) de pose et de dépose de traverses qui reçoit une traverse (8) dans la région du bogie à changer pour la pose et la dépose à partir des rails en surélévation. Le système de levage constitué par les deux cadres de levage en traverse (5, 6) et la plate-forme (4) est de dimensions extérieures réduites et sa hauteur est peu importante en position rétractée (abaissée); comme le mouvement de levage est en deux temps, on obtient malgré le manque de hauteur de la structure une hauteur de levage relativement importante. Grâce à des systèmes à pantographe (14), la plate-forme peut être déployée de manière stable et sans risque d'atteindre son moment de renversement, ce qui lui permet de recevoir des charges même à partir d'une position excentrique.

Abstract: This invention relates to a mold clamping apparatus for an electric injection molding machine which can eliminate deflection of a toggle mechanism and non-uniformity of a push force applied to a movable platen resulting from the former, can be produced at a low cost and has excellent operation response. The mold clamping apparatus (1) is equipped with upper and lower toggle portions (6, 7) including ball screws (61, 71) disposed symmetrically with each other and outwardly in a radial direction with respect to the axis of the apparatus, heads (62, 72) meshing with the ball screws and links (63 - 65, 73 - 75) expanding and contracting with reciprocation of the heads along the ball screws, and each ball screw is connected directly to the output shaft of corresponding one of two servo motors (8, 9) connected to a control circuit (20) containing a pulse width modulation control circuit and two transistor inverters. Principal constituent components of the mold clamping apparatus are spaced apart from the axis and deflection of the toggle mechanism (6, 7) and non-uniformity of a push force applied to the movable platen (5) due to deflection can be eliminated. Since each servomotor may be of compact type that can drive only one toggle portion, the mold clamping apparatus is economical and has high operation response.

Abstract: Method for production of ribbed reinforcing steel, a steel wire being produced by hot rolling and, in the process, provided with oblique ribs and, if required, longitudinal ribs (in particular according to DIN 488). The steel wire (5) hot-ribbed in this way is subjected to cold stretching and its yield strength and elongation are thereby adjusted. The steel wire (5) is stretched continuously and, for this purpose, is guided over at least two driven stretching pulleys (1, 2) (or stretching rolls) working at different peripheral speeds on the steel wire (5). The degree of stretching is controlled via the difference in the peripheral speed of the two stretching pulleys (1, 2). The yield strength and elongation are controlled via the stretching rate. The invention also discloses an arrangement for carrying out the method. <IMAGE>

Abstract: The invention relates to aqueous solutions of sodium salts of trimercapto-s-triazine, whose molar saturation concentration at 0 to 40 DEG C is above the saturation concentration of the trisodium salt of trimercapto-s-triazine (TMT-Na3), where more than two, but fewer than three, H atoms of the trimercapto-s-triazine are replaced by sodium ions. The solutions preferably contain the disodium salt of trimercapto-s-triazine (TMT-Na2) besides a little TMT-Na3. Surprisingly, the solubility in water of TMT-Na2 exceeds that of TMT-Na3. The solutions are a suitable commercial form for the active substance trimercapto-s-triazine (TMT-H3), which is used in the separation of heavy metals. They are prepared by reacting TMT-Na3 with TMT-H3 in a molar ratio of 1 : greater than 0 to less than 0.5, in particular 1 : 0.1 to 1 : < 0.5, in aqueous phase.
