  • Patent number: 10759551
    Abstract: An ejection head for an ejection device of a sealing machine for sealing a container includes a supporting element with a supporting axis and a sliding end, and a sliding element for sliding the supporting element along a sliding profile of the sealing machine. The sliding element is arranged at the sliding end and a force acting essentially in the direction of the supporting axis is capable of being transmitted via the sliding element to the supporting element. So that the sliding element and the sliding profile are subject to reduced wear, the sliding element is a rotatable rolling element, so that in the operating state the supporting element is capable of being unrolled over the rotatable rolling element along the sliding profile.

  • Patent number: 10639647
    Abstract: Pusher centrifuges having screen drums rotatable about axes of rotation are used for separating a mixture into solid cake and into liquid phase. Pusher centrifuges may further have pusher bases arranged in the screen drums and arranged to be movable to and fro alternately in a first pushing direction and a second pushing direction along the axis of rotation that are used in order for the solid cake to be alternately displaced along the axis of rotation. The mixture is introduced into a first empty space or into a second empty space using a feed device. The first empty space is established on a displacement of the solid cake by the pusher base in the first pushing direction and the second empty space is established on a displacement of the solid cake by the pusher base in the pushing direction opposite to the first pushing direction.

  • Patent number: 10363500
    Abstract: A double-action pusher centrifuge separates a mixture into solid cake and liquid. The pusher centrifuge includes a screen drum rotatable about an axis and in which a pusher base device is arranged to be movable along the axis of rotation. The solid cake is displaced by an outer ring region of the pusher base device. A plurality of axial passage openings are disposed in the outer ring region and connect front and rear regions of the screen drum. A feed unit is arranged at an inflow disk such that the mixture can be introduced via the feed unit and the inflow disk into empty space on the screen drum on displacement of the solid cake. An inflow gap applies the mixture into the empty space, and is between an inflow edge of the inflow disk and a pusher base plate of the pusher base device with an inflow region.

  • Patent number: 6547972
    Abstract: The invention relates to a centrifuge comprising a rotating drum (1) and comprising an ejection element (2) which rotates together with the drum in order to eject a cake (3) of solids, which is deposited on the inner side of the drum, in the axial direction (4). The ejection element (2) has a helix (5) which extends over the length of the drum. The helix (5) and the drum (1) are kinematically connected in such a manner that a reference point (A) at the circumference of the helix executes a rotational movement relative to the drum in the form of a sawtooth line (6, 8), with a first flank (7) of the sawteeth (8) corresponding approximately in its inclination (&agr;) to the pitch (&bgr;) of the helix whereas a second flank (9) of the sawteeth (8) corresponds to an approximately axial ejection movement.

  • Patent number: 4313373
    Abstract: Apparatus for pitting dates wherein an endless apron consisting of plates with sockets for dates is transported stepwise by two chains past a hopper which dispenses randomly distributed dates onto the upper sides of successive plates, past an adjustable elastic refuser which intercepts overlapping dates and directs some intercepted dates into empty sockets, past a rotary brush which inclines partly inserted dates in a direction counter to the direction of movement of the plates, past a centering station wherein semicylindrical extensions of tubular centering elements penetrate into the sockets of the adjacent plate to promote or cause complete penetration of partly inserted dates into the respective sockets, and thereupon past a removing station where the cutting edges at the leading ends of reciprocable tools penetrate into the sockets to expel pits from the dates.
