Abstract: The present application describes a rail clip assembly, particularly but not exclusively for securing a crane rail to a flanged girder. The assembly comprises a first part (1) adapted to be attached to the rail support surface adjacent the rail, a second part (2) overlying the first part and having a lateral surface (3) for abutment with a lateral face (4) of the rail, and fixing means (7) for fixing the second part to the first part independently of attachment of the first part to the rail support surface. The parts (1,2) have aligned apertures (8,9) through which the fixing means extends, one of the apertures (8) being elongate to enable the second part to assume different positions relative to the first part. The elongate aperture (8) extends in a direction inclined at an acute angle to the longitudinal direction of the rail. The first and second parts have cooperating laterally directed surfaces (12,13) which are abutted in all relative positions of the parts for transmitting to the first part laterally directed forces applied to the second part by the rail. The laterally extending surfaces (12,13) extend parallel to the direction of extent of the elongate aperture (8). The first part   (1) has parallel upper and lower surfaces and the second part has an upper surface (14) which, adjacent the aperture, is inclined to the horizontal away from the direction of approach of the cooperating laterally directed surfaces (12,13) to the rail. The fixing means (7) extends through the apertures in a direction perpendicular to the inclined surface of the second part (2) and thus inclined with respect to the vertical.

Abstract: Immunological reagents, consisting of a) antibody or fragment conjugates having both an anti-cell specificity and an anti-hapten specificity, and b) synthetic tracers containing at least two hapten sites and at least one site suitable to attach radioactive isotopes, paramagnetic ions, drugs, or toxins, are provided. These reagents are capable of binding to target cells in a specific way, and the tracer localizes preferentially on the membrane of antigen-bearing cells, even in the presence of excess antibody conjugate (affinity enhancement). These reagents are usefully employed, either in vitro or in vivo, to detect tumors, metastases, or other tissue injuries, when the synthetic tracer carries radioactive or paramagnetic compounds, and to kill target cells when the synthetic tracer carries radioactive compounds or drugs or toxins.

Abstract: This bed base consists of slats (2) of lengths which may be identical or which may vary according to requirements. These slats (2) are joined together by straps (3) of suitable measurement, notched (3<1>) at uniform intervals (Fig. 8). These straps may be in one piece when the side of the bed base is straight or in several pieces (3<2>) when the side is not straight. They are then placed in an offset continuation arrangement. Straps cut at the same level make it possible to divide the bed base into several parts (3<3>). The ball joints (Fig. 1 and 2) are flexible, articulated, independent and self-supporting, with a wide base forming suckers. The upper sheath (11) bordered with lateral slots whose lips may move apart enables the slats to slide whilst gripping them. The hollow (7) below the curved lateral lugs (13) permits articulation. The strengthening ball joints (1<2>) are identical to the support ball joints (1). The lower hollow (7) can provide a passage for a strengthening slat (15) when the centre of the bed base is not supported. Figures seven and eight illustrate the abstract. Support ball joints (1), slats (2), notched straps (3), offset notched straps (3<2>). Strengthening ball joints (1<2> ) placed in the middle: for a double bed base; in pairs: to strengthen one or more slats. <IMAGE>

Abstract: Le dispositif et le procédé décrits servent à placer dans une position essentiellement verticale des éléments de conduite se trouvant dans une position essentiellement horizontale, en relation notamment avec un derrick se trouvant de préférence sur une plate-forme de forage flottante. Afin de supprimer les dispositifs existants de stockage vertical de conduites et tout équipement de manipulation de conduites associé et en même temps afin d'obtenir une structure de derrick simplifiée et une plate-forme ayant un point de gravité situé à un niveau inférieur, on produit selon la présente invention un dispositif de manipulation comprenant une unité allongée (51), fixée de façon rotative au niveau de sa première extrémité (52) au dispositif de levage (53) du derrick et disposée au niveau de sa seconde extrémité (56) de façon à pouvoir se déplacer le long du plan de travail (58) de la plate-forme de forage. L'unité (51) comprend un organe de serrage (59, 64) servant à maintenir des longueurs de conduite (60, 60n) constituées de préférence par des éléments de conduite préassemblés (60a, 60b, 60c). Etant donné que le dispositif de manipulation de conduites suit le mouvement du dispositif de levage, on risque moins facilement de perdre les conduites dans le trou de forage et on obtient une économie de temps totale et un forage plus suivi.

Abstract: Un convertisseur (20) intensité/pression (I/P) fournit une pression de sortie en fonction de l'importance d'un courant CC d'entrée variable. Le convertisseur I/P (20) comporte un capteur de pression (64) qui délivre un signal de retour représentatif de la pression de sortie. En fonction du signal de retour et de l'importance du courant CC d'entrée, un signal de commande électrique est engendré qui commande un dispositif (40) pour moduler la pression de sortie. Le convertisseur I/P (20) comporte également un circuit (86) pour engendrer un signal variable dans le temps, qui est renvoyé par les fils de la boucle de courant (28) qui véhiculent le courant CC d'entrée. Le signal variable dans le temps fournit une indication du fonctionnement correct du convertisseur I/P (20). Il est ainsi possible de diagnostiquer les causes d'anomalies du système de commande sans qu'il soit nécessaire de contrôler le convertisseur I/P (20) lui-même.

Abstract: The difficulty of making Doppler shift velocity measurements in a chirp pulse echo ranging system is overcome by employing a pulse frequency compression filter, suitably a SAW compressor (45), having individual outputs (64, 65, 66, 67) respectively relating to adjacent contiguous frequency bands each having a bandwidth approximately equal to the chirp frequency swing. Signal detection and processing means (70) senses the occurrence of a compressed pulse on any of the outputs and measures the amplitudes of signals on all the outputs. A computer (120) then computes the Doppler shift from the amplitude ratio of the sensed signals in adjacent frequency bands, determines the target velocity therefrom and uses the result also to correct the range measured by the counter (5).
