  • Patent number: 5017177
    Abstract: The present invention relates to a maize sheller having at least one drum and counter drum (concave). The counter drum has an adjustable part and a non-adjustable part. The maize sheller according to the invention possesses a regulating mechanism for regulating clearance between the drum and the adjustable part of the counter drum. The use of a counter drum of such a construction economizes a significant amount of metal and enhances the screening capacity and the productivity of the entire device. The regulation of the outlet aperture within a comparatively wide range permits the use of the maize sheller for shelling corn cobs of different sizes and with different moisture content without causing damage to the grain. In case of penetration of foreign matter into the shelling apparatus, the drum and the counter drum are protected against deformation by a safety sector which is automatically opened.

  • Patent number: 4991561
    Abstract: A gas-air mixer for internal combustion engines having an inlet and an outlet diffusor and being mounted in a collar member which forms a cyclindrical surface between them. Feeding channels are disposed between the inlet and outlet diffusors which terminate at the external side of the diffusors in a concentrically shaped annular channel. Both diffusors are constructed as separate bushings. The outlet diffusor is fixedly mounted in the collar and the inlet diffusor is movably mounted in the collar, around its axis by means of a control lever. The diffusors are seated end face to end face and an outer cylindrical surface mutually defined by them through which have been cut radial slots form feeding channels for gas fuel. By turning of said diffusors with respect to each other the cross-section of the feeding channels is adjusted depending on the angle of rotation of the inlet diffusor around its axis different operating regimes of the engine.

  • Patent number: 4989402
    Abstract: The invention relates to textile machine control. The run of spinning units is controlled by two busses, a two-way bus, and a reserve one-way bus, the latter being activated, as a rule, by a central electronic system, and possibly, though less often, by the operator. A suitable arrangement of the circuits on the criterion of whether they belong to the two-way bus or to the one-way one, facilitates troubleshooting and permits shorter repair time on vast systems comprising a plurality of work stations of the textile machine.The invention can be used on various types of spinning machines where a predetermined length of wound yarn is required.

  • Patent number: 4967803
    Abstract: Method of preparing a weft and its removal from an open shed in jet weaving machines automates the preparatory operation of weft upon finding a weaving fault. This is achieved by performing both the preparation and the withdrawal of the weft in the course of the first quadrant of the jet weaving machine revolution. The method includes the step of supplying a further unseparated weft length, forming a loop between the unseparated weft length in the open shed while the loop elongates due to the action of an inserting medium until the loop face emerges from the shed on the shed outlet side and removing the weft from the shed by a weft withdrawing device.

  • Patent number: 4966624
    Abstract: A method for electric refining of lead with alternating current in which the basic stage of the process is preceded by two stages, a preparatory stage and an initial stage. The preparatory stage involves pretreatment of the electrode surfaces by means of alternating current of equal width and amplitude of the forward and reverse pulses. During the initial stage there is effected an electric refining with alternating current having reduced current density.A circuit for electric refining of lead with alternating current has two controllable current rectifiers, each of which is connected to a separate group of electrolytic baths. The groups of electrolytic baths and the controllable current rectifiers are connected in series and opposite to one another.
