Title: Apparatus for irradiating articles
IPC: G21K5/02
Filed: 1970-09-08
Abstract: An irradiation apparatus comprises a radioactive source consisting of two independent cylindrical radio-active elements associated co-axially in end to end relationship one on each side of a horizontal plane of symmetry of an irradiation zone, a horizontal platform on which rows of articles to be irradiated can be arranged around the source and means for moving the rows successively along different linear paths in turn so that each article makes at least one complete circuit around the source and successively occupies each of a number of possible positions. Preferably the source unit is that indicated generally as 21 in Fig. 4 and each of the source elements 22 and 24 is provided with a positioning and storing mechanism comprising a source carrier e.g. 32 closely sliding in a cylindrical cavity e.g. 30 in a substantially hemispherical shield 28, each source carrier being rotatable about a horizontal axis e.g. 38 within the cavity, the source being brought into an irradiation position, as exemplified by source 22, or shielded, as exemplified by source 24, by rotating the source carrier about its cylindrical axis. The rotation of these carriers may be remotely controlled from outside by means of pulleys and flexible cables (Fig. 5, not shown). Preferably the axis on which each of the source carriers is mounted is situated below the centre of gravity of the assembly mounted on it when the source is in the irradiating position, so that the release of a locking device enables the source to return automatically to its shielded position by the force of gravity alone without relying on external power. The articles are preferably pushed around by rams. The source and conveyer systems are contained in a conventional shielded chamber.

Title: Filament quenching apparatus and process
IPC: D01D5/092
Filed: 1970-02-09
Abstract: As shown in Fig. 1, an apparatus for quenching melt extruded filaments of a synthetic organic polymeric thermoplastic material comprises an entry chamber 1 for a cooling gas (preferably air) formed by outer cylindrical neoprene rubber bellows 2 which surrounds an inner cylindrical neoprene rubber bellows 3 in a concentric manner thereby forming a gas entry chamber of annular cross-section. Cooling gas entering the chamber 1 is passed through filter felt 4 and then through perforations in the wall of a perforated metal cylinder 5 into a porous, multi-cellular, polymeric foam diffuser 6. The cooling gas is diffused in diffuser 6 and enters quench chamber 7 as a substantially non- turbulent stream before quenching filaments 8 extruded from spinneret assembly. The cooling gas then passes downward through quench chamber 7 into and through the cooling stack 10 and is discharged therefrom. The filaments emerging from the stack 10 are drawn and collected in take-up means 11. Spinneret 9 is surrounded by a cylindrical wall 12 which surrounds and encloses the filaments which are extruded from spinneret 9. The rubber bellows 2 is connected to the inner flange 13 of the wall 12 and the metal cylinder 5 is connected to the inner flange 14 of the wall 12. The bottom of the cylinder 5 is connected to the outer flange 15 at the top of the stack 10 which serves as a further cooling chamber for the quenched filaments. The inner bellows 3 is connected to the upper part of the stack 10. The filter felt 4, which may be of woven or non-woven felt material, is wrapped around the metal cylinder 5 and serves to provide a means for producing an additional pressure drop across the diffuser 6 and to filter dust from the cooling gas prior to its entry into the chamber 7. The diffuser 6 is held in place by a flange 17 at the bottom of the wall 12 and a flange 18 at the top of the stack 10. The diffuser 6 can be cut from porous bulk material or can be fabricated from slab stock. It may be preferably to 2 inches thick and have a length (generally parallel to the axis of the quenching chamber) of preferably 6 to 24 inches. The diffuser 6 has preferably 75 to 150 cells per linear inch and a cellular void volume of preferably 75 to 97% of its total volume. The bulk density of the polymeric foam of which the diffuser consists is preferably 1À4 to 6 lbs per cubic foot and the foam may be flexible or rigid. The preferred diffuser material is a polyurethane foam, but it may be a polyvinyl chloride or polyvinyl acetate foam, or a natural or synthetic foam rubber.
