The present invention relates to a chamber for a centrifuge wherein the longitudinal circulation of air in the chamber is assisted. This is achieved, for example, by a specific form of lid for the chamber.

This disclosure is directed to a fluid envelope, e.g., water bed, frame comprised of an underlying pedestal assembly, an intermediately located platform upon which the fluid envelope rests and an upper rail section containing a plurality of side rails and end rails secured together at their ends by a plurality of common fastening means. The underlying pedestal section is comprised of two or more notched support members having positioned thereon in mating fashion a plurality of pedestal cross mem...

A dispenser has an outlet nozzle which is reversibly movable by rotation of a control cap from a first extended position, in which adhesives is dispensed as a series of fine spots, to a second retracted position in which adhesive is dispensed as a film using the flat upper surface of the control cap as a spreading tool. The base of the nozzle is joined to the walls of the dispenser by a flexible membrane. The control cap is provided with a centrally located hole, in the flat upper surface, throu...

A device in a submersible pump or mixer prevents solid bodies from entering a housing containing a mechanical seal. The device has a helically formed groove so directed, that pollutant material is fed in a direction away from the mechanical seal, and the device has a cutting means to cut the pollutant material.

The application describes a valve device which can be used to open and shut a laterally arranged inlet in an inclined wall of a mixer granulator and which can be used in an automatic operation. The valve device comprises a main body (1) and a piston (2), the piston being movable between a retracted position and an advanced position. The piston (2) comprises a face (3) at its forward end which is inclined to the direction of movement and the device comprises means (24,19) to rotate the piston as ...

A sheet material comprising discrete depressions which are at least partially filled with micronized medicament and which are useful as or in a drug delivery device. This sheet material is useful in devices which provide for aerosolization of the medicament, for delivery to a patient by inhalation.

The present invention relates to a device for administering a fluid medicament to an infant via a teat in fluid flow communication with a reservoir for the fluid medicament, characterised in that the device comprises: a. a teat having an inlet at or adjacent its proximal end to receive fluid from the reservoir and an outlet at or adjacent its distal end through which fluid fed to the teat from the reservoir is adapted to flow into the mouth of a user; b. a conduit within the teat directly connec...

A filtering device for an injection device which includes a syringe and a needle affixed to the syringe. The filtering device comprises an elongated hollow tubular element mounted on the medical injection device to surround and sealingly enclose the needle. The end of a tubular element remote from the tip of the needle is open for the introduction of fluids therethrough into the hollow interior of the tubular element. A nonfiber releasing filtering member for filtering fluids is provided which i...

In a lock comprising a rotor and a stator, the rotor being rotatable in the stator by means of a key from a first position to a second position, the improvement comprising means defining a first abutment associated with the rotor for rotation therewith, means defining a second abutment mounted in the lock nonrotationally relative to the axis of the rotor, the second abutment being in such engagement with the first abutment as to block rotation of the rotor from the first position to the second p...

A device for protection of a semiconductor device comprises a metallic wire and means for connecting said wire to the output of said semiconductor device, said metallic wire having a characteristic that when a current a little lower than the current that destroys said semiconductor device flows through said wire, said wire is melted in as short a period of time as possible.
