  • Patent number: 9074697
    Abstract: The invention relates to a valve flap (1) for producing a casting machine valve (100), in particular for installing into a casting machine for casting a flowable substance, in particular a liquid substance with suspended solid particles, such as chocolate for example, in which cocoa particles and sugar particles are typically suspended in a molten fatty substance that has cocoa butter and milk fat to a greater or lesser extent. The valve flap is designed such that a valve can be produced with at least one other valve element, said valve consisting in particular of at least two valve flaps (1) that are preferably identical.

  • Patent number: 8733230
    Abstract: Devices for the preparation of a liquid food or beverage. One device includes a housing, pump, pump support for securing the pump to the housing, a rigid duct that is connected by an elastic sealing member to the housing and to an inlet or outlet of the pump. The pump support includes an elastic support member for resiliently supporting the pump chamber in the housing. Another device includes a pre-suction chamber connected to a liquid inlet of a pump and being designed to intermittently provide liquid to said liquid inlet. A further device includes a connector of at least one elastic sealing member designed to absorb vibrations from a pump of the device and to enable a relative movement of a duct and a liquid inlet or outlet of the pump.

  • Publication number: 20120132284
    Abstract: A method is provided for portioning a flowable, optionally pressurized mass. In a first step a first pinch valve is opened and a second pinch valve located thereafter in a principal flow direction of the mass (m) is slightly closed. As soon as a desired quantity of the mass has passed the pinch valves the first pinch valve is closed. The second pinch valve is then opened. The opening, the slight closing and the closing of the first pinch valve and of the second pinch valve is accomplished by a pressure medium. A controller, a valve arrangement and a portioning device are also provided for executing the method.

  • Publication number: 20110315024
    Abstract: The invention relates to a casting machine valve (32, 42; 50; 60; 70; 80; 90; 100; 110; 120; 130), a pressure generating means (3, 4, 5, 6, 32, 42) for installation in a casting machine (1), and a casting machine (1) for casting a flowable mass, particularly a liquid mass having suspended solid particles, such as chocolate, wherein cocoa particles and sugar particles are typically suspended in a melted fat mass containing cocoa butter and more or less milk fat. The valve (50; 60; 70; 80; 90; 100; 110; 120) comprises a valve body (51; 61; 71; 81; 91; 101; 111; 121; 131) having a valve opening and at least one valve cap (53; 64; 76; 83; 94; 105; 115; 128; 133) that is associated with the valve opening, is hinged on the valve body, and closes the valve opening in the unpressurized state without preloading.

  • Patent number: 6983534
    Abstract: The invention relates to a continuous process and an apparatus for partially exposing conductor tracks in fully insulated laminated cables according to specifiable parameters selectable in accordance with the subsequent conditions for use. The object of the invention is to insert windows in exactly predetermined parts above/below individual/all flat conductors of a multiconductor flat cable, which windows are distinguished by clean and accurate contours and furthermore ensure good positional stability of the conductors. The flat cable (1) is first fed to an apparatus and fixed on it in such a way that an individually feedable and individually movable peeling tool (5) can be coordinated in a defined manner with each flat conductor, both from above and from below, which peeling tool effects first an incision in the insulation layer, then peeling off down to the flat conductor and finally separation of the chip (10).
