Abstract: Cold skull melting crucible for melting small quantities of metal in suspension. The crucible contains the crucible pan in its upper part while with the base part (2) it can be flanged onto a low- pressure line or a corresponding apparatus. The crucible pan is formed from end segments (1) which are separate from one another and manufactured individually and joined together, and in which cooling channels (6) run, in which supply lines (7) for the cooling agent, which start from the base part (2), are arranged, the base element (2) containing the supply and removal line for the cooling system. In this connection, removal pipes (8) for the cooling agent, which project from the base part, serve as connecting part between the upper part and the base part (2). The aim of the invention is a design of the crucible in which there is no hole in the central crucible region. This is achieved by means of a wall segment (1') which includes the centre of the pan and which is both designed as a flat segment and can also be formed in such a manner that it fits and fills a circular central opening, left free by the other wall segments (1), on the bottom of the crucible pan. <IMAGE>

Abstract: Method for hardening reinforcing bars for concrete, in particular weldable reinforcing bars produced by hot rolling, the reinforcing bars being subjected to cold mechanical deformation in a continuous process and thereby adjusted, inter alia, in respect of their yield strength and breaking elongation. The reinforcing bars are subjected to multi-stage bending, without torsion, around a bending roller (5, 6) in various equidistant, mutually offset bending planes and thereby cold work/hardened in the bending planes along a plurality of superposed axes. In the process, a lengthening of the reinforcing rods is achieved. The yield strength and breaking elongation are adjusted by the extent of this lengthening. A device for carrying out the method is also disclosed. <IMAGE>

Abstract: According to the invention, since the axis (L3) of a needle (38) is inclined with respect to an imaginary plane perpendicular to the axis (L2) of a lower shaft (28), the lowermost position of the needle (38) where it comes closest to a loop taker (30) is spaced from the loop taker (30) in the axial direction thereof in proportion to the degree of inclination of the axis (L3) of the needle (38). As a result, the length of a bobbin (61) accommodated in the loop taker (30) can be extended along the axis (L2) thereof, thereby permitting the amount of bobbin thread loaded on the bobbin (61) to be increased. At this time, the amount of needle thread drawn by the needle thread take-up may remain the same as in the previous construction and need not be changed, which serves to eliminate the problems such as thread breaking or difficulty of thread cast-off.

Abstract: Facteurs neurotrophiques chimériques comprenant au moins une partie d'un facteur cellulaire naturel et une partie d'au moins une autre molécule de sorte que la molécule chimérique obtenue présente une activité neurotrophique. L'invention est basée, en partie, sur la découverte que des molécules chimériques comprenant des parties à la fois de facteur de croissance des nerfs (NGF) et de facteur neurotrophique dérivé du cerveau (BDNF) sont susceptibles de posséder une activité neurotrophique, et dans certains cas elles présentent un spectre d'activité plus grand que celui des molécules parentes. L'invention est également basée sur la découverte que des molécules chimériques comprenant des séquences de facteurs neurotrophiques ainsi que des séquences de peptide supplémentaires peuvent conserver une activité neurotrophique, et dans certains cas elles peuvent présenter une activité plus puissante que le facteur parent. Les molécules de facteur neurotrophique chimérique de l'invention présentent un certain nombre d'avantages par rapport à des facteurs neurotrophiques naturels. On peut utiliser les facteurs neurotrophiques chimériques afin d'obtenir, par exemple, l'activité de deux facteurs neurotrophiques dans une seule molécule où ils peuvent servir de superagonistes d'un facteur neurotrophique endogène, permettant ainsi d'obtenir une réponse biologique accrue à des doses inférieures.

Abstract: The charge transfer device of the invention is provided with a four-phase drive system register in which first, second, third and fourth transfer sections (21 to 24) sequentially arrayed constitute one bit. The first, second, third and fourth transfer sections are arranged such that, when applied with drive pulses of the same level, a potential difference occurs between the first and third transfer sections and the second and fourth transfer sections. Also, charges are transferred by four-phase drive pulses (φ₁ to φ₄) such that the first (21) and second (22) transfer sections go to high level and the third (23) and fourth (24) transfer sections go to low level during the first transfer interval, the first, second and fourth transfer sections go to low level and the third transfer sections goes to high level during the second transfer interval, the first and second transfer sections go to low level and the third and fourth transfer sections go to high level during the third transfer interval, and the first transfer section goes to high level and the second, third and fourth transfer sections go to low level during the fourth transfer interval. A primary advantage of the invention is an increase of the data rate by reducing the charge transfer time in the four-phase drive system register in the CCD solid state image sensing device.
