Abstract: L'invention se rapporte de façon générale aux domaines de la biolgoie moléculaire et à la production de protéines recombinantes au moyen de myxomycètes cellulaires du gène Dictyostelium, et plus particulièrement à de nouvelles souches du gène Dictyostelium, à des plasmides recombinants utilisables avec des souches du gène Dictyostelium, ainsi qu'à des polypeptides qui facilitent la réplication extrachromosomique de ces plasmides dans des souches du gène Dictyostelium. L'invention se rapporte en particulier à un polypeptide qui facilite la réplication extrachromosomique d'un plasmide recombinant dans des espèces de Dictyostelium où le plasmide recombinant contient une origine de réplication dérivée d'un plasmide de type Ddp2, mais auquel il manque les gènes fonctionnels pour la réplication extrachromosomique dans des espèces de Dictyostelium de type sauvage. Les plasmides de réplication extrachromosomique obtenus selon la présente invention sont appropriés pour véhiculer une grande variété de gènes et de séquences promotrices en vue de la production régulée de protéines recombinantes par l'industrie biotechnologique.

IPC: A47K1/14
Filed: 1991-08-24
Abstract: The present invention relates to an outlet device for washbasins or similar, having a valve upper part (5), which is to be mounted above the washbasin and is closable by means of a valve stopper (7), and a substantially pot-shaped valve lower part (1), which is assigned to the valve upper part (5) and is to be mounted on the underside of the washbasin and which has a laterally branching connection piece in which is mounted the ball of an eccentric rod (9), upon whose actuation the valve stopper (7) can lift. According to the invention, the outlet device is characterised in that the cylindrical pipe socket (13) of the valve lower part (1) receives a cylindrical part (17a) of a plastic insert (17) and the cylindrical pipe socket (13) has, on one side in the pipe wall, a downwardly open aperture (21), through which a bearing bush (3), moulded laterally on the plastic insert (17), for supporting the ball (10) of the eccentric rod (9), extends radially outwards. Since the surface working of the laterally moulded-on bearing bush (3) can be dispensed with, the manufacture of the pot-shaped valve lower part (1) is considerably more efficient. <IMAGE>

Abstract: A system for optimizing control of separately excited shunt-wound dc motors, where optimization is achieved through microprocessor-based independent PWM control of a chopper (armature) and an H-bridge (field). Connected to the armature is an armature voltage amplifier for varying the applied armature voltage. A field voltage amplifier is also provided for determining the direction of motor rotation and varying the voltage applied to the field winding. A first sensor is connected to the motor armature in order to determine the motor rotational speed. A second sensor is connected to the armature circuit in order to determine the armature current. A third sensor is connected to the field circuit in order to determine the field current. A decoupling controller uses the motor speed and armature current information, and adjusts the armature voltage and the field voltage. An optimal controller uses the motor speed, field current and armature current information, and adjusts the armature voltage and the field voltage.

Abstract: A safety cover for an electric receptacle has a mounting plate fitting over an electrical receptacle, and a cover assembly with a cover edge extending around the periphery thereof, the mounting plate having an edge engagable surface thereon corresponding in shape to the cover edge. The cover assembly is mountable on the mounting plate between a closed and an open position. The cover assembly has a plurality of locking projections spaced around the periphery of the cover assembly at positions so that they are incapable of simultaneous operation by a hand below a predetermined size. When the cover assembly is closed, locking hooks on the locking projections engage in locking hook receiving apertures in the mounting plate structure and the cover edge is snugly abutted against the edge engagable surface. The cover assembly can be moved to the open position only by simultaneous deformation of the cover assembly at the positions of the locking hooks sufficient to move the locking hooks sufficiently far inwardly of the cover assembly to free the locking hooks from the locking hook receiving apertures.
