Publication number: 20120132284Abstract: 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.Type: ApplicationFiled: February 10, 2010Publication date: May 31, 2012Inventor: Leo Bühler

Publication number: 20110315024Abstract: 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.Type: ApplicationFiled: October 21, 2009Publication date: December 29, 2011Applicant: BÜHLER AGInventors: Boris Ouriev, Hannjo Boden, Bernhard Bauer, Leo Bühler, Andreas Diener

Patent number: 6983534Abstract: 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).Type: GrantFiled: October 18, 2002Date of Patent: January 10, 2006Assignee: Schleuniger Holding AGInventors: Dietmar Zeibig, Leo Bühler

Publication number: 20040025661Abstract: An apparatus is proposed which makes it possible to produce contact windows only for one conductor track or a plurality of individual conductor tracks in the flat cable. The other conductor tracks should not be influenced or impaired. A flat cable is transported in a guide channel through the apparatus. For each conductor track of a flat cable, a cutting disk is present above and a pressure element below. As soon as insulation is to be stripped from an area, the actuating element is actuated and the pressure element is raised. As a result, the flat cable is pressed with the insulated conductor track against the cutting disk and the insulation layer above the conductor track is removed.Type: ApplicationFiled: June 16, 2003Publication date: February 12, 2004Inventor: Leo Buhler
