Title: Method of and apparatus for the tape loading and use of a single turntable in the rendition of a taped program
Inventor: JOHNSON JOSEPH R
IPC: B65H20/26
Filed: 1977-10-27
Granted: 1980-01-29
Abstract: Abstract of the Disclosure A turntable is rotated to wind the tape of a taped program thereon in equal lengths per revolution thereof.  Each equal winding forces the preceeding windings inwardly on the turntable to assume progressively curving paths as the respective windings recede from the periphery of the turntable.  Pressure pads are equally spaced around the periphery of the turntable and rotate therewith.  The pressure pads extend radially, and frictionally engage the top edges of the tape windings which follow increasingly curved paths there-between as the equal windings are forced inwardly by succeeding equal windings.  The ends of the tape are connected leaving a por-tion of the closed loop formed thereby for engagement by associated apparatus and rendition thereby of the taped program.  Since all of the windings on the turntable are of the same length per rotation thereof, tape can be simultaneously wound on and off the turntable as it is rotated with no slippage and friction between windings, and as the beginning and end of the taped program are joined, the program can be repeated for as many performances as desired, with only moni-toring for mechanical failures required.

Abstract: ABSTRACT OF THE DISCLOSURE           The present invention relates to a control system for a multi-stage reducing apparatus through which elongate material is advanced and reduced in cross section.  The invention is particularly suitable for use in connection with apparatus, e.g., metal strip rolling mills and wire drawing machinery, having a series of material reducing stages through which elongate material is continuously advanced and progressively reduced in cross sectional area.  The apparatus includes means for generating a set of signals representing the cross sections of the material at each of the stages, means for generating a speed control signal representative of the speed of the material at one stage, and control means responsive to the cross section signals and the speed control signal and operable for producing a plurality of speed reference signals for controlling the speed of the material at each stage, each such reference signal being proportional to the speed control signal and the ratio of the cross section of the material at said one stage and the cross section of the material at the respective stage.  The control means is preferably embodied as a plurality of analog arithmetic units, for the plurality of stages, each responsive to the speed control signal and to the cross section signals of said one stage and the respective stage and operable for generating an output signal corresponding to the product of the speed control signal and the ratio of the cross sections of the material.

Granted: 1981-08-11
Abstract: Apparatus for heat sealing a thermally-sensitive material to a substrate material includes a frame, and a pair of internally heated shafts mounted fast on the frame.  A roller member is rotatably mounted on each shaft, and is arranged to be heated by the heating element within the shaft.  The rollers are rotated in opposite angular directions so that an object interposed at the nip will be translated therebetween.  The facing peripheral portions of the roller members each have a sinusoidal cross-section, with the peaks of one roller member being aligned with the valleys of the other.  The roller members are spaced from one another to provide a degree of frictional resistance with the materials to be bonded together.  The cross-sectional configuration in the roller members serves to provide a plurality of ribbonlike seals between the materials, without propagating a bubble as such materials are passed between the roller members.

Abstract: ABSTRACT OF THE DISCLOSURE       A spark gap device in a high-voltage direct current interrupting device maintains a substantially constant ignition voltage by constructing the spark gap device in at least two series-connected main spark gaps connected in parallel with a voltage divider for distributing the voltage across the main spark gaps.  An ignition voltage-determining auxiliary gap is connected in series with an impedance con-nected in parallel with one or more of the main spark gaps to effect a continued ignition thereof.  The ignition voltage of the high-voltage direct current interrupting device is determined by the auxiliary gap such that the auxiliary gap is not subjected to appreciable wear whereby the variations of the ignition voltage are relatively small and not influenced by the wear of the main spark gaps.

Abstract: COMPOSITE CARTRIDGE AND DEVICE FOR   METERING EXTRUSION OF CONTENTS              Abstract of the Disclosure The invention provides structural components for making a composite cartridge and the resulting composite cartridge.  The cartridge contains, in separated condition therein, two different fluid compositions which cure on mixing.  The cartridge has an elongated cylindrical main body with a protruding round neck at its head end and plunger-movable closure means at its butt end.  One composition is enclosed in an inner central chamber having a disc-like closure.  The other is in an outer ring chamber oriented coaxially about the central chamber and having a donut-like closure.  Each chamber is connected to a separate passageway through the round neck of the cartridge.  A means solely at the head end braces the central chamber against relative movement within the cartridge during plunger extrusion of the compositions.  A fastening means on the cartridge neck is for locking a mixing nozzle thereon.  Also provided is an assembly of the cartridge releasably mounted on apparatus for simultaneous metering extrusion of the separated compositions from it.  The apparatus comprises a frame, and a plunger assembly of coaxial elements mounted in and guided by the frame for linear advancement as a unit with respect thereto.          The frame is equipped with a holding means for retaining the cartridge with its butt end closures axially aligned anteriorly to the coaxial elements of the plunger assembly.

Abstract: GRATE PREHEATER KILN SYSTEM     ABSTRACT OF THE DISCLOSURE         Grate burner fuel supplies additional heat to the grate preheater for accomplishing more calcining.  A cooler recoup system directs cooler recoup air to the grate fuel burner as preheat combustion air for the fuel burner.  The cooler recoup air is also directed to the grate preheat zone as preheated combustion air for fuel in the pellet bed.  Cooler recoup air is also directed to the drying zone.  The cooler recoup system is controlled so that excess cooler recoup air is bypassed to the waste gas system to dump excess air.  Also, a cooler recoup fan speed or damper is regulated to control kiln firing hood pressure by varying the flow.  In addition, there is provided the cooler recoup excess air bypass damper for controlling duct pressure to stabilize air flow in the system by varying the flow to the waste gas system.  The dis-closed apparatus operated according to the method herein dis-closed provides improved fuel economy, more effective control and reduction in waste gas, thus reducing heat consumption to provide improved fuel economy with better control of the pre-heating and drying operation.
