摘要:
A touch-sensitive sensor arrangement comprising a planar-shaped element having a surface provided with a conductive layer, and a plurality of connecting points that are each arranged in an edge area of the element and contacting the conductive layer, wherein a respective decoupling device is arranged for decoupling a current, which is applied to at least two connecting points, from an evaluating signal, between each of the respective connecting points and associated connecting lines for the evaluation of a position of a contact of the element with a contacting object, where the element is heatable by the current.
摘要:
A yarn feeding funnel for a textile spinning machine having an upper shaft portion and a body portion. An axial yarn passage extends through the shaft portion and an outlet passage extends at an inclination downwardly and outwardly from the axial passage to an opening on the surface of the body portion. The body portion above the opening extends to a greater axial extent than the opening and may be an inverted frusto-conical shape or a torus shaped flange or a cylindrically shaped flange. Alternatively the opening may be in an annular recess in the body portion.

The apparatus for making textile fiber strands has a principal drive unit and at least one auxiliary drive unit. At least one alternating current motor of the principal drive unit is provided with a supply current of an adjustable frequency by a frequency converter. The frequency converter or at least one of the frequency converters is connectable to at least one alternating current motor of at least one of the auxiliary drive units in an intermediate time interval in which the receiving members of the apparatus for the fiber strands being produced are not loaded with the fiber strands.

An improved ring spinning machine for making a filled bobbin of yarn, thread or the like comprises at least one ring rail which moves up and down near a plurality of spindles driven by a ring rail drive. A control for the ring rail drive in case of an unforeseen machine stoppage, is arrayed so as to cause the ring rail drive, when it would otherwise drive the ring rail in the upward direction on restart because the ring rail was moving up at the time of shut-off, to reverse so that the ring rail moves downward no later than the time of restart of the spindles, so that the ring rail moves downward after the unforeseen machine stoppage at the beginning of restart thus providing for a safer, more reliable spinning operation.
摘要:
In a ring spinning or other textile machine with a multiplicity of thread-winding stations each including one or more variable-speed motors, a central controller supplies periodic or continuous timing signals to respective speed setters of all stations for a predetermined progressive speed change of the associated variable-speed motors. In a specific embodiment, the timing signals are recurrent pulses for the advance of identical programs of the local speed setters whereby the several stations will follow the same routine but with possible relative staggering in time, taking individual delays due to thread breaks or the like into account.

A method for manufacturing thin-film chip resistors, in which method a resistor layer (14) and a contact layer (15, 16) are applied onto the upper surface of a substrate (10) and structured using laser light so as to form on said substrate (10) a plurality of adjacent, separate resistor lands (24) having a predetermined approximate resistance value, allows the simplified and cheap manufacturing by performing the electrical insulation of the resistor elements (24) and the structuring of the individual resistor lands (24) for the entire resistor land simultaneously by means of a laser-lithographic direct exposure method.
