    摘要： An improved twin screw extruder device (14) is provided which is capable of producing a wide variety of high quality extrudates having greatly varying final properties, without the need for extensive machine. The extruder (14) includes a barrel (16) together with a corotating twin screw assembly (22). The assembly (22) is made of a pair of srews (50,52) having central, tapered shafts (54,56) equipped with outwardly extending helical flighting (58,60); the srews (50,52) are non-parallel and are positioned so that the flighting (58,60) thereof is intercalated along the length of the srews (50,52). The flighting is of specialized configuration and tapers along the length of screws (50,52) preferably at an angle of taper different than that of the shafts (54,56); moreover, the width of the outer flighting surfaces (70,72) increases along the length of the shafts (54,56). This screw geometry defines a series of alternating upper and lower close-clearance high-pressure nip areas (78) defined by the flighting (58,60) which serves to propel an extrudable forwardly towards the outlet end (20) of the barrel (16). However, passageways (80) and kneading zones (82) are also defined between the screws (50,52), which assures full mixing, shearing and cooking of the material. The extruder device (14) is capable of producing high density sinking aquatic feeds as well as expanted, low density products merely by changing the rotational speed of the screws (50,52) together with appropriate temperature control. In another embodiment, fluid extraction extruder (138) is provide having a specialized extruder head (140) including an outer shell (144) and an inner, elongated, slotted sleeve (152).

    摘要： A two-component thermosetting polymer system is formed and dispensed by adding a foaming agent to one of two components of the polymer system. A solution of the foaming agent in the first component is formed in a supply tank. The foaming agent and first component solution is then mixed with a second component at a dispensing head or nozzle. By adding the foaming agent to only one of the two components and, in particular, by forming a solution of the foaming agent in the first component one is able to very carefully control the foam density of the cured end product.

    摘要： The present invention relates to a component-feed nozzle for use with a reactive-mixing head of a reactive-injection apparatus encompassing a housing (12, 13) with a component-inlet (18) and with a nozzle-shaped component-outlet (15), and to a seal (16, 17) inserted in the housing (12, 13) by means of a drive (30) so as to be displaceable between at least two positions, where, in a first position, the seal (16) seals the component-outlet (15), and in a second position the component-outlet (15) is free and there is a flow connection between the component-inlet (18) and the component-outlet (15). In order to avoid surmounting a reactive force during a displacement, it is proposed that there is a seal-and-throttle unit (16, 17) which has at least one area of a first type (A1, A3) and one area of a second type (A2), which on application of the component pressure generate a force in an opposite direction, where the sizes of the areas (A1, A2, A3) have been selected in such a way that the opposed forces substantially offset one another.
