Title: Raw material feeder in particular for extrusion machines
IPC: B29C31/02
Filed: 1988-02-15
Abstract: The subject of this invention is a device for raw material feeding, in particular into an extrusion machine or other equipment relying on continuous or intermittent feed of raw materials, that allows for an easy selection of position of the bin depending on the local conditions. There is equipment known to feed raw materials by means of spring loaders (coiling) according to a French Patent No 530 328. In this approach and also in other similar solutions the construction of the dumping end of the loader makes it difficult to change the location of the loader with the bin attached to it in relation to the equipment being fed. There are known applications aimed at achieving this by using elastic materials for casing but it has a negative effect on the durability of the casing and also the spring because the transport has to be along a curve. In the current invention, an intermediate element, a socket, was employed between the dumping end of the spring loader and the dump bin. The connection between the round dumping end equipped with a stopper ring and the bin is achieved by means of a socket with a blocking clamp. The design of the socket allows for a full turn of the spring loader along the axis of the dumping end in relation to the bin. It is also possible to change the location of the spring loader in the horizontal plane due to the slidable mounting of the socket and sleeve in guides with handles for the positioning of the dumping end after the optimal location of the spring loader in relation to the bin has been selected. The subject of this invention is depicted in examples, where Fig 1 illustrates the general view and Fig 2 shows the cross-section of the device in the A-A plane.

Filed: 1993-03-19
Abstract: The method designed for obtaining organic cyclical sulphites with the general formula I, where R refers to H, CH3, CH2Cl, C6H5 or CH2OC4H9. The method consists in copolymerization of ethylene oxide with SO2 in the presence of a Lewis base or ammonium salt, followed by the decomposition of the resulting polymer. Characterized in that: The copolymerization of ethylene oxide - with the general formula II, where R refers to H, CH3, CH2Cl, C6H5 or CH2OC4H9 - is realized with an equimolar amount or with up to double surplus of SO2 at the temperature of 30-60 degrees C for 1-6 hours. The Lewis base or ammonium salt are added in the amount of 0.5-5 percent by weight of the ethylene oxide. The decomposition process of the resultant polymer is carried out in the presence of 1-5 percent by weight of Lewis acid, protonic acid or trimethylchlorosilane, with respect to the weight of ethylene oxide, at the temperature of 40-60 degrees C, for 4-6 hours.
