Abstract:
The instant invention is related to a single conveyor system for carrying bobbins about a spinning machine wherein the conveyor system is capable of handling both empty bobbins and bobbins wound with a strand of yarn and the like and of sorting the wound bobbins doffed from the machine from empty bobbins being supplied to spindles upon the machine for winding.
Abstract:
In order to provide fast response to control signals for modifying high pressure fluid flow paths such as air at 80 psi through large orifices by use of thin flexible diaphragms, a movable control element is positioned with two ends disposed between two thin impervious flexible diaphragms which can be deflected to move the element in opposite directions. Pressure chambers acting on each diaphragm cause the control element to move as a function of the differential pressure. In one pressure chamber positioned in alignment with one end of said control element is a valve nozzle through which the controlled fluid flows. Thus the control element may squeeze the diaphragm against the nozzle to control fluid flow in response to fluid input pressures. This basic control element is used variously as a flow amplifier, a threshold detector, a latching thyratron type relay, and a pressure divider, with the control element having opposite end contact surfaces of different area used to vary the ratios of differential pressure which may move the element into a valve control position. A further movable element is used as a biasing source to oppose the movement of the control element in proportion to fluid control pressure bearing thereupon. The ''''Not'''' function of inverting signals is achieved by overcoming the biased element tending to close a vented nozzle with an input signal to open the vent and reduce the pressure of the biasing source.
Abstract:
Dynamic operating conditions of a fluid logic integrated circuit module are shown on a front panel circuit schematic diagram with dynamic pressure indicators located for viewing at monitored schematic circuit positions to provide diagnostic information for servicing or monitoring a system sequence. The module comprises a sandwich array of two logic element plate layers with an intermediate taut flexible elastomer diaphragm layer common to a plurality of logic elements spaced on the two logic plates with mating cavity wells for the individual logic elements disposed on opposite sides of the diaphragm. Adjacent one logic element plate is the pressure indicator panel having a foam layer common with a plurality of indicator units, which are connected to preselected monitor points in the module to display the states of the elements and the pressure conditions of the supply fluid sources or input and output channels. A back panel includes a visual circuit connecting diagram for the particular custom circuit showing where to connect hoses between various modular access channels, so that the systems can be connected and put into service on-site by unskilled personnel. A set of indicators thus connected into any particular circuit design is set apart for viewing in position on a schematic circuit overlay on the front panel which blocks out the unused indicators in the module.
