Abstract: A device for guiding powdery fluidic media, in particular powder paint, including a receptacle which is provided with an inner chamber for the media which is to be guided, and from where the medium is suctioned via a connection channel which can be closed by a valve body. The connection channel and the valve body comprise, respectively, an upper end area formed in such a manner that an annular Venturi nozzle is formed therebetween which is used as a pump. The valve body is inserted in a sealed manner in the end region of the connecting channel by a sealing section when in the closed position thereof and comprises a conveyor gas channel which can impinged upon by conveyor gas, through which the conveyor gas can be guided to the connection channel in the vicinity of the sealing section, essentially, in the direction of flow of the medium.

Abstract: An AC LED package and circuits are disclosed along with an AC LED driver. The AC LED circuit may include as few as one LED or an array of anti-parallel LEDs driven with AC power sources and AC LED drivers at various voltages and frequencies. The AC LEDs are pre-packaged in various forms and materials and designed for mains or high frequency coupling in various forms to AC power sources, inverter type drivers or packages. The AC LED driver is a fixed frequency driver that provides a relatively constant voltage output to different size loads within the wattage limitation of the driver and in some cases is a direct mains power source.

Abstract: An electrochemical battery cell comprising a cell housing defining an inner space, a first terminal and a second terminal; and at least one pre-formed pellet disposed within the inner space of the cell housing. The pellet includes an outer electrode portion formed from a material to geometrically define the pellet in a solid form. The outer electrode portion is in electrical communication with the first terminal of the cell housing. The pellet also includes an inner electrode encapsulated by a separator and embedded within the material of the outer electrode portion. The inner electrode is in electrical communication with the second terminal of the cell housing and electrically insulated from the outer electrode material. In a preferred embodiment, the inner electrode comprises an anode and the outer electrode portion comprises a cathode portion.

Abstract: The present invention relates to a loading device for a shoe press having a shoe press roll (1) and a mating roll (2) for forming a press nip, preferably in a dewatering device such as in a papermaking machine, through which press nip at least one paper web is guided for dewatering. The shoe press roll (1) has at least one press shoe (4) and at least one supporting device (5), and the press shoe (4) and the supporting device (5) are connected by a multiplicity of hydraulic devices, in order to load the press shoe (4). The invention is characterized in that the hydraulic device has at least one first guide element (7) for guiding a cylinder sleeve (8) substantially linearly, and the cylinder sleeve (8) engages at least in sections into at least one second guide element (9) which is connected to the press shoe (4) in a substantially stationary manner.

Abstract: The invention relates to a sanitary washstand fitting, comprising a housing which is detachably secured to a washstand with the aid of a fixing device. The fixing device comprises a base which can be fixed to the washstand, an insertion device enabling the housing to be placed on the base from the top, and a clamping device enabling the housing thus arranged to be clamped against the base. The clamping device comprises a spring ring which is received in a groove of the base and which is radially expandable by means of a threaded pin such that it can also be engaged in a complementary counter groove in the housing.

Abstract: Methods and compositions for treatment, diagnosis, and prevention of a virus comprise administering to a patient antibodies which react with regions of viral proteins and result in neutralization of infectivity and inactivation of functionally essential events in the life cycle of the virus. The antibodies recognize viral epitopes which fail to elicit an immune response in man when encountered through infection or naturally through the environment. In a preferred embodiment, the invention provides compositions and methods useful in the treatment and diagnosis of human immunodeficiency virus (HIV) infections. The present invention is also directed to chemical conjugates (herein referred to as MDP) adjuvant microparticle-antigen conjugates) that have a muramyl dipeptide backbone crosslinked into a microparticle capable of binding to the cell surface of Antigen Presenting Cells (APCs), to which is covalently attached one or more molecules having a reactive carbonyl group (i.e.

Abstract: A powder supply system for a powder-coating installation, especially a parts painting installation using electrostatic powder, according to the invention, comprises a tank designed to contain the powder, means for feeding powder into the tank, means for injecting compressed air into the bottom of the tank in order to fluidize the powder, and an exit pipe in which the powder is entrained by the air from the tank, this pipe being connected to at least one powder using device situated at a distance, in particular a spray gun. The system also includes means for reducing the pressure in the tank below that of the feed means in order to fill the tank with powder.

Abstract: In order to set up digital image acquisition in classic panoramic X-ray machines, the invention proposes providing a row of detectors in the cartridge unit of the machines, said row of detectors being arranged or being able to be arranged behind the recording slit. The output signals from the row of detectors and the output signals from a rotary encoder are wirelessly transferred to an evaluation unit. Retrofitting the digital image acquisition thus does not require any intervention in safety-related parts of the panoramic X-ray machine.

Abstract: A tool for removing conventional one way fasteners that includes, generally, a member, a collar, and, a shaft that can be removably received by the collar, wherein in the shaft is configured to engage regions of the fastener head. The collar is adjustable to fit fastener heads of different sizes. The member can be configured to correspond to a threaded portion of the outer surface of the collar. The collar may also have a bottom portion that includes multiple splines.

Abstract: A method and apparatus for moving magnetic material includes an electromagnet for lifting the magnetic material where upon its release, the residual magnetic flux of the lifted magnetic material is reduced. The apparatus includes a generator coupled to the electromagnet. The generator includes a control input and an armature having a voltage output. A controller has an output coupled to the generator's control input and armature voltage output, whereupon receiving a release material signal from an operator interface panel to release the magnetic material from the electromagnet, the controller transmits a plurality of control signals, one of which is at least partially dependent upon the duration of a previously transmitted control signal, to effectively alternate the polarity and reduce the magnitude of the magnetizing force of the electromagnet.

Abstract: In order to ensure consistently good maceration of biological material in an electroporation reactor, it is proposed to monitor the conductivity of the mixture therein and to detect any arcing which occurs therein. The results of such monitoring are used to modify the operating voltage of the electroporation reactor and/or the composition of the mixture located in the reactor channel.
