The invention falls within the sector of bottling plants. In a method for capping containers (2) with crown caps, the step of centering the cap is performed without the container (2), the cap being completely free to arrange itself in position on a movable magnetic element (4). The capping machine has capping means (7, 11) which are eccentric with respect to the capping axis (20) and positioned at a higher level than the zone for capping the container (2).

Designed for use primarily with needles carrying radioactive material in which the syringe is inserted into a radiation shield, the device includes a freestanding support having a planar shield on the upper end of a stem extending upwardly from a base. A central aperture through the shield and into the stem includes an upstanding portion having a chamfered outer end. The lower end of the radiation shield surrounding the syringe includes an inwardly tapered or chamfered bore so that self centerin...

A rotary action graphic recording system includes a pen carriage supporting a plurality of recording pen shuttles in a linear array together with means for moving the pen carriage in a carriage path. Each pen shuttle supports a recording pen having a downwardly extending tip. Rotary actuation means are supported by and operative upon the pen carriage to engage selected ones of the recording pen shuttles for movement of the pen tips into contact with the recording media. The rotary actuating mean...

A process is disclosed which provides for the reduction of the occurrence of oxidative and/or thermal degradation of polyphenylene oxides by contacting the oxides with a capping agent in the presence of a water soluble base, a catalytic phase transfer agent, and, optionally, an effective organic phase reducing agent. The resulting capped polyphenylene oxides can be used to prepare improved articles of manufacture using conventional techniques such as molding, vacuum forming, extrusion, etc.

A liquor bottle capping assembly comprising a perforated member fixedly attachable to the liquor bottle in covering relationship with a threaded opening in the liquor bottle for preventing flame propagation into the liquor bottle.

A rotary type capping apparatus for screwing caps onto the mouths of containers includes a turn table provided with a plurality of container holders fixedly mounted along the periphery thereof, a main motor for rotating the turn table in a predetermined direction and a capping head assembly including a plurality of cap holders, each of which is disposed above the corresponding one of the plurality of container holders, so as to be movable closer to or away from the turn table. In one aspect of t...

An improved method for crystallizing amorphous or polycrystalline material is disclosed, which method employs a novel intermediate product. A film of material to be crystallized is formed on a substrate. A porous silica cap is formed over the film. The resultant intermediate product is heated to melt the film which crystallizes upon cooling. Gases generated during melting of the film escape through the porous cap which also functions to prevent deleterious agglomeration of the material while it ...

Apparatus for attaching rigid, conventional ridge tiles to a roofing structure is disclosed wherein elongated members extend along either side of the roof ridge so as to support the lateral edges of the conventional ridge tiles. The ridge tiles are supported on both elongated members such that the tiles extend over the ridge of the roof. Since the tiles merely rest against the elongated members, a plurality of locating and retaining straps are utilized to retain the ridge tiles on the elongated ...

An apparatus is disclosed for automatically dispensing cups to a continuously moving flight conveyor having openings for receiving the cups and carrying the same continuously forward through a cup-filling station, a cup capping station and a cup discharge station. A cup filling means travels forwardly while filling the cups and a heat sealer means heat seals cups to the cup rims while traveling forwardly with the cups. At the discharge station, the cups are automatically lifted and transferred f...
