The invention relates to a device for producing a fluid containing a radioactive constituent, the device comprising: a shielded chamber (5) within which is located an isotope container (6) housing a radioactive isotope (7), the shielded chamber including first and second fluid connections (12,13) to opposing ends of the isotope container and a fluid conduit (14,15) extending from each of the first and second fluid connections to a fluid inlet (16) and a fluid outlet (17) respectively characteris...

A yarn withdrawal device for open-end spinning arrangements has a yarn withdrawal nozzle and a balloon-breaking insert which extends the axial channel of the yarn withdrawal nozzle. The yarn withdrawal nozzle has a curved contact surface for deflecting a yarn to be withdrawn and simultaneously rotating the yarn in a crank-like manner, which contact surface graduates from a front surface into the axial channel. The balloon-breaking insert has an inner wall which is provided with raised areas and/...

An invented hinge for coupling three buoyant-slats pool cover sections together is described wherein three, modified, longitudinal buoyant slats are coupled for pivoting around three angularly spaced, parallel hinge axes aligned with the slats by a plurality of hinge plates each defining a coupling aperture received and pinned within registering hinge bays penetrating into adjacently positioned, longitudinal side flotation chambers of the three modified buoyant slats by a longitudinal hinge pin ...

A channel plate adapter 24 is provided for an open-end spinning arrangement 1 having a spinning rotor 3 which turns at a high number of revolutions inside a rotor housing 2 chargable with an underpressure. The channel plate adapter 24 is made of a plastic material, defines the orifice area of a fiber guide conduit and a center through-bore 26 for a yarn withdrawal nozzle 27, and is adapted to be exchangeably arranged in a receiver 22 of a fiber channel plate 10 for closing the rotor housing duri...

A flashlight with power supply adapter comprising a front light housing with a light bulb in the tip of the main body of the flashlight. There is a compartment in the main body for storing a rechargeable battery and a spare battery. There are also an on/off switch and a battery select switch for selecting between the rechargeable battery and the spare battery. During use, when the power of the rechargeable battery is drained, the flashlight can still be made to work by changing the battery selec...

The oxidation behavior of the bond coat is improved using a HVOF nanostructured NiCrAlY coating. NiCrAlY powder is mechanically cryomilled and HVOF sprayed onto Ni-based alloy to form a nanocrystalline bond coat. Oxidation is performed on the coating to form the thermally grown oxide layer (thermally grown oxide). After heat treatment at 1000.degree. C. for 24 and 95 hour, a homogeneous .alpha.-Al.sub.2O.sub.3 layer is formed on top of the bond coat. The nanostructured characteristic of the coat...

A folding chair has a hinges on the seat and on a back panel and on a brace. The chair further includes side frame elements to which the seat, back panels and brace are all hingeably connected. The chair can be folded into a very compact form.

An open-end rotor spinning device comprising a spinning motor rotatable at high speed inside a rotor housing subjected to low pressure and closable by a covering element. A single motor-driven opening cylinder rotates in a opening cylinder housing. A fiber guiding channel (18) includes an output-side channel section extending in a channel plate adapter whose installation position in the covering element is specified by its position with regard to the spinning rotor, and an input-side channel sec...

A sunshade includes a post having a rib-mounting member mounted thereon. A plurality of ribs, each having a rib end, are pivotally connected to the rib-mounting member. A runner is slidably mounted on the post. A plurality of stretchers each have a stretcher end pivotally connected to an intermediate portion of an associated rib and a runner end pivotally connected to the runner. An illuminating device is mounted in the runner or the rib-mounting member. Damage to the illuminating device is avoi...

A fiber guide channel for pneumatic transport of individual fibers combed from a sliver by an opening cylinder of an open end spinning device for delivery to a spinning rotor. The fiber guide channel is arranged in a cover element for the rotor housing and the input side of the fiber guide channel is matched in its width to the mountings of the opening cylinder. The inlet and the outlet openings of the fiber guide channel have a slot-like shape and the maximum extension (B) of the inlet opening ...
