Abstract: A three-dimensional print head apparatus may include a securing mechanism, a hopper, a nozzle, a heating system, and a fume extraction system. The securing mechanism may be adapted to secure to a wrist joint of a robotic arm. The hopper may have a cavity and a lower aperture and may be secured to the securing mechanism. The nozzle may have an upper aperture and a lower aperture. The heating system may be positioned along the barrel.

Abstract: Disclosed herein are systems and methods of facilities location, in which a customer activates an application and that application determines, from the GPS device, a location and the locations of the various cables or equipment buried in their yard. The customer may mark the service location using the supplied information on the device application. In an example embodiment, if the customer has further questions, he may call into the center, for example, by pressing a voice button, to talk to a person regarding the questions. In this embodiment, a two way communication is enabled to provide the customer with additional assistance in locating the facilities.

Abstract: A resource catalog system comprises a catalog organized as a set of metadata structures representing distributed system resources, language for resource invocation, and a query interpreter and optimizer. Query optimization includes dynamic functional composition by modeling resources according constraints and determining constraint-satisfaction to compose an execution plan. Query optimization may also include dynamic selection and scheduling of resources by combining a resource scheduling with adaptive feedback. The resources may comprise distributed software components, application programs, shell scripts, executables, and services. The resource catalog system accepts queries for operations on distributed resources through a declarative language or a procedural language. A query optimizer derives catalog operators from a query or elsewhere and accesses the system resources according to interpretation of the catalog operators.

Abstract: A rack-and-pinion electro-steering system, e.g., for motor vehicles, has a rack extending in a housing, which is operatively connected to a thrust member/pinion pairing. At least one bearing between the rack and the housing is provided for guiding the rack. The bearing is arranged as a friction bearing. A construction of the bearing between the rack and the housing as a sliding bearing may be particularly suited for a reliable, durable and cost-effective guidance of the rack in the housing. In addition, for mounting the sliding bearings on the rack, a lock geometry is provided by which the sliding bearings may be locked after having been mounted on the rack. The lock geometry for example may be based on the lock geometry customary in sealing rings in automatic transmissions.

Abstract: The invention relates to a process for improving the effectiveness of the removal of zirconium from an aqueous, zirconium-containing nuclear fuel and/or fertile material solution in nitric acid in a liquid-liquid extraction process.Accordingly, the object of the invention is to improve the removal of zirconium from the reprocessing solutions and, at the same time, to simplify the course of the process. The invention seeks to improve decontamination of the uranium product and the plutonium product while, at the same time, reducing the outlay involved.According to the invention, this object is achieved in that, in a process step carried out before the first extraction of the nuclear fuels and/or fertile materials, the zirconium is converted from the dissolved state into a filterable or centrifugable solid phase by the use of an adsorbent from the group of inorganic ion exchangers and is removed from the aqueous solution together with the adsorbent.

Abstract: An IV holder is used in combination with an IV stand having a post, an IV-liquid supply on the stand, and a tube extending from the supply to a recumbent patient adjacent the stand. The holder comprises a clamp body releasably secured to the post, an elongated pole having an inner end fixed to the clamp body and an outer end and extending horizontally from the clamp body and post, and a spring on the outer end of the pole connected to the IV tube between the patient and the supply and holding the tube up in the air above the patient. The outer end of the pole is above the patient, to which end the pole is at least 24 in long. In addition the spring is a tension spring having an upper end secured to the outer end of the pole and a lower end releasably secured to the tube. This spring is stiff enough so that it can hold up the tube, but not so stiff that it prevents the tube from being pulled freely down.

Abstract: A process for the separation of neptunium from an organic phase, which is developed in the recovery of irradiated nuclear fuel and/or fertile material. The organic phase contains uranium-, plutonium- and neptunium ions, tritium in the form of tritiated water and fission products in ionic form, as well as an organic extraction agent dissolved in diluent. After a first wash step, and before the organic phase is further fed to a uranium-plutonium separation or to a uranium-plutonium coreextraction, the organic phase is brought into contact with an aqueous solution containing diluted HNO.sub.3, butyraldehyde and a low concentration of sulfamic acid in countercurrent flow as a second wash step for the selective reduction of Np (VI) to Np (V) and for selective stripping of Np (V), with respect to U and Pu, from the organic into an aqueous phase.
