Title: Screening method and apparatus
Inventor: TOHKALA ANTTI
IPC: B07B13/18
Filed: 1992-12-02
Abstract: The present invention concerns a screening method and apparatus for sorting wood chips into three categories, namely, accept chips, overthick and/or overlong chips requiring further processing and reject fines. The chips are fed onto a disc screen. A major portion of fines and a portion of accepts fall by gravity through clearances between the discs (1) of the disc screen and a portion of the chips travels over the disc screen. Screening of chips on the disc screen is cut short before all accept chips have fallen through the disc screen. Chips travelling over the discharge end of the disc screen are routed onto a roller screen (10), whereby the remaining portion of accepts can fall by gravity through the roller screen while overthick and/or overlong chunky chips are conveyed over the discharge end of the roller screen.

Title: Multi-use drum of plastic and a process for manufacturing and reconditioning this
Inventor: SCHUETZ UDO
IPC: B65D51/22
Filed: 1993-12-15
Abstract: ABSTRACT            In order to manufacture a screw-cap drum (1) that can be used as a multi-use drum, a circular heating ring is installed on the rim (18) of the drum body (2) from above and a screw-cap cover (6) that has an annular extension (23) that is moulded onto the underside of the cover flange (17) and which is coaxial to the axis of the cover is placed on the heating ring.  After a heating period that melts the annular extension (23) that is arranged on the cover flange (17) and the annular bead (26) that is formed on the drum rim (18), the cover (6) and the heating ring are raised. Then the cover (6) with the annular extension (23) is placed on the drum rim (18) under pressure and with the cover seal (16) pre-tensioned, in such a way that the annular extension (23) on the cover flange (17) is joined to the annular bead (26) on the drum rim (18) to form an annular closing piece (20) that connects the cover flange (17) and the drum rim (18) to each other.  In order to recondition the screw-cap drum (1) after single or repeated use, the screw-cap cover (6) is separated from the wide-neck drum body (2) by culling the connecting piece (20).  The drum body (2) can then be converted to form a wide-neck drum with a simple cover and a clamping ring closure of sheet metal, or can be converted to form a drum with a screw-cap cover or a screw-cap drum with a welded-on or moulded-on screw-cap cover.

Abstract: ABSTRACT  The plug is intended to be coupled to a container which holds an enamel for nails or the like.  The application may be effected by actuating sideways a push-button (15) or by pressing axially an annular push-button (21). By acting on the push-button (15, 21) a canula (9) is displaced axially and acts upon the plunger of the pumping device (4) which is part or is mounted on the mouth of the container holding the enamel.  When releasing the push-button, the product is ejected to the bristels (13) of a brush-type applicator which emerges from a trunco-conical nozzle (19) integral with the body. The trunco-conical nozzle (19) is sealingly closed by means of a thread cap (20) and carries inside an obturating bell which is adapted to the conical periphery of the nozzle and which is spring-biased (30).
