Abstract: "SHEET FOLDER"                   Abstract Bed sheets are moved in an unfolded condition along their lengths on a horizontal conveyor, grasped at the opposite sides of their leading edge, stretched at their leading edge and fed into a nip roll of a folder.   The nip roll progressively moves the sheet down an inclined guide plate toward a first clamp assembly.  The first clamp assembly holds the leading edge of the sheet, and the sheet is spread away from the first clamp assembly into a second, facing clamp assembly.  The second clamp assembly grasps the sheet and the first clamp assembly releases the sheet, and the sheet is spread away from the second clamp assembly toward tile first clamp assembly, the first clamp assembly regrasps the sheet as the second clamp assembly releases the sheet, and the progressive, alternative spreading and clamping functions continue to draw the sheet into the clamp assemblies and fold the sheet in an accordion fold.  The sheet is then conveyed along its folded length out the ends of the two clamp assemblies to a winding fork where the according folded sheet is grasped by and folded about the winding fork in a flat spiral configuration and then is moved off the ends of the tines of the winding fork.

Abstract: Abstract A digital spark and dwell ignition control system is disclosed.  Maximum advance and reference sensors are uti-lized to determine positions of maximum and minimum possible advance for spark ignition with respect to the position of the engine crankshaft.  For each maximum advance sensor pulse a main counter starts sequentially counting clock pulses wherein the maximum count obtained by the counter is related to engine crankshaft speed.  The count of the main counter is utilized by a dwell circuit to determine the time prior to the maximum advance pulse at which spark coil excitation should occur.  The main counter count also deter-mines several inputs to a read only memory (ROM) circuit whose output controls a rate multiplier.  The rate multi-plier receives input clock signals and provides selective frequency division for these clock signals in accordance with the ROM output.  The output of the rate multiplier is coupled to an accumulator means, preferably a series of counters, which provides an accumulated count corresponding to the rate multiplier output.  The accumulated count is utilized to determine the occurrence of spark ignition. Pulse width modulation circuitry receives an analog signal related to the amount of sensed engine vacuum pressure and produces a corresponding periodic digital two state signal which has a duty cycle related to the magnitude of the analog vacuum signal.  The periodic two state digital signal is coupled as an input to the ROM which controls the rate multiplier means.  In this manner the accumulator count is -?-made to depend upon the magnitude of the analog vacuum signal while a minimum amount of ROM storage space is utilized.

Abstract: 7                   48,456 ABSTRACT OF THE DISCLOSURE The  separation  rate  of  an  oil-in-water or  a water-in-oil emulsion is increased by first determining the HLB number of the emulsion and then adding to the emulsion a surfactant which has the opposite HLB number. The HLB number of the emulsion can be determined by iden-tifying whether the emulsion is an oil-in-water emulsion or a water-in-oil emulsion and using an HLB number of 3 to 7 if the emulsion is an oil-in-water emulsion and an HLB number of 7 to 18 if the emulsion is a water-in-oil emul-sion.  The type of emulsion can be determined by measuring the electrical resistance, a resistance of less than 1000 ohms indicating an oil-in-water emulsion and a resistance of more than 1000 ohms indicating a water-in-oil emulsion.

Abstract: RCA 74, 541 ABSTRACT OF THE DISCLOSURE         A horizontal deflection generator includes the series arrangement of a horizontal deflection winding and a trace capacitor, a retrace capacitor, and a horizontal trace switch.  The trace switch comprises a damper diode and a horizontal output transistor.  Base drive for the horizontal output transistor is provided by a horizontal driver stage through a driver transformer.  A secondary winding of a flyback transformer is coupled to a high impedance cascade rectifier arrangement to form a DC supply which provides collector supply voltage for the driver stage. The DC supply has a relatively large source impedance to changes in the load current being drawn from the supply by the driver stage.  Such a large impedance is desirable in order to limit the base driver to the horizontal output transistor during picture tube arc-over and to allow for duty cycle tolerances in the horizontal oscillator output.
