Abstract: A circuit arrangement for a piezoelectric positioning element is formed of a series connection of a capacitive element, an inductance, and first switch to be controlled, said series circuit being connected across at least one piezoelectric body of the positioning element. The capacitive element, which may be another piezoelectric body of the same positioning element but which is operated in reverse phase, has at least approximately the same capacitance value as a capacitance of the first piezo-electrical body. The inductance is dimensioned sufficiently large in order to magnetically intermediately store substantially an entire energy increment to be transferred between the positioning element and the capacitive element. The first switch is connected to permit termination of a charge transfer. A series circuit is formed of an electrical energy source for charging and recharging and a second switch, said series circuit being connected parallel to the positioning element or the capacitive element. A controllable short-circuit switch is connected parallel to the capacitive element or parallel to the positioning element. In this way, the activation energy of the piezoelectric body is recovered on de-activation, for re-use on the next cycle.

Abstract: For cyclically charging the filling tube of a sausage stuffing and closing machine with ready-for-stuffing tubular casing lengths, a tubular casing material flatly wound upon a supply roll is first withdrawn, opened and, in respectively one section length, drawn upon a support. Thereupon the drawn-on casing section is divided off the material cord and, along with the support, is placed ahead of the charging tube for conveyance thereto while at the same time, a new casing section is drawn onto another support to repeat these working steps in permanent alternation of the two supports. The invention resides in that each support after being placed ahead of the charging tube along with the casing section drawn thereonto is pushed in the same direction in which the drawing onto the support was performed beforehand, onto the charging tube up to the stopping means, whereupon the support is advanced in the same direction, pulled out of the retained casing section and, finally, removed laterally. This will save precious time until a new charging operation starts and enhance the degree of efficiency. A corresponding apparatus for implementing the method is equally suggested.

The filter core or its wrapper coaxially surrounds a filter shell (114) whose diameter corresponds to the diameter of the outer shell. An air-impermeable wrapper (115), which also serves to connect the strand part and the filter element, surrounds the filter shell. A ventilation zone (116) is incorporated into the air-impermeable wrapper for the filter shell. A smoke mixing zone (120) for changing, in a defined manner, the smoke mixture leaving the strand part before it flows into the filter element is designed in the transition region between the strand part and the filter element. <IMAGE>

Abstract: Patente de Invenção:<B>"MéTODO PARA A RECICLAGEM DE POLICARBONATOS AROMáTICOS"<D>. Os policarbonatos são reciclados sem a necessidade de modificação química por dissolução em um solvente seguido da remoção de quaisquer materiais insolúveis e da precipitação por adição de um não-solvente. A etapa de precipitação pode ser seguida por polimerização de estado sólido do policarbonato reciclado. Particularmente, quando a polimerização de estado sólido deve ser feita, o uso de uma combinação de solvente e não-solvente que produz um intermediário cristalino é realizado, e o uso de um reagente modificante que aumenta a concentração de grupo terminal hidróxi do policarbonato pode ser vantajoso.
