Abstract: ABSTRACT OF THE DISCLOSURE          A torsional vibration damper of the type having a hub which carries an outer inertia ring coupled thereto by an elastomer.  Supplemental damping is added to the system via the use of dry friction.  A broad frequency range of effectiveness is provided by designed non-linearity of the device made possible by the dry friction.          A greater broadening of the frequency range of effective-ness is made possible by utilizing a plurality of inertia masses carried by the hub, all mounted on the same elasto-mer.  Elastomeric compression is utilized to spring-load the friction surfaces, providing a series-parallel, elas-tomer viscous-dry friction damping medium.  In multiple mass application the concept of mass interaction is utilized to further determine the dynamic performance of the damper.

Abstract: Abstract An integrated logic circuit is formed on a layer of semi-con-ductive material of one conductive type.  The first region of the opposite conductivity type is formed in the layer with no contact means formed on or in it so that no external electrical signals can be applied to the first region.  A second region of the one conductivity type is formed within the first region and provides, with the first region and the layer, a vertical transistor structure.  Third and fourth regions of the opposite conductivity type are formed in the layer at positions spaced away from each other and from the first region so that the layer forms the base region of both a first lateral transistor comprising the fourth and third regions, and of a second lateral transistor comprising the third and first regions.  Means operable to inject current into the layer performed in the base region of both lateral transistors through the fourth region.  An input circuit for applying input voltage signals to the third region to control the current distribution between the two lateral transistors and thus the current supplied to the first region is formed in the base region of the vertical transistor.  An output circuit comprises the controlled current path of the vertical transistor.  the vertical transistor is normally operated so that the second region acts as the collector zone.  One or more further regions of the opposite conductivity type may be formed in the layer at positions spaced away from each other and from the first, third and fourth regions.  Each further region has an individual further input circuit whereby a pattern of input voltage signals applied simultaneously to the third and further regions determines the base currents applying to the base of the ver-tical transistor.

Abstract: ABSTRACT OF THE DISCLOSURE         A piston type internal combustion engine is arranged to use, in a time dependent process, the shock compression and expansion waves generated by the com-bustion of the fuel to pump highly energized compressed air from a reservoir chamber adjacent the combustion chamber and in communication with the latter through a restricted passageway into the combustion zone during the entire combustion process.  The combustion chamber, reservoir chamber and passageway are configured to pro-mote controlled pumping of air from the reservoir into the combustion chamber throughout combustion due to the interaction of the compression and expansion waves.  The air in the reservoir is fuel-free and is preferably placed in the reservoir during an aspirated intake event by controlling the timing of fuel flow during intake and the mixture of the charge at the intake port.  The pre-ferred embodiment provides the reservoir chamber in the piston near its working face and the passageway is an annular gap between a radial lip of an annular member supported above the piston and the cylinder wall.

When a text measure is wider than the width of a display device, only a portion of the text can be displayed at one time.  By divid-ing the text into segments, all of the text can be ultimately displayed.  This is done automatically dependent upon the current location of a cursor positioned within one of the lines of the text.  Entire lines of text, including a scale line, are sequentially loaded into a line buffer beginning with the line containing the cursor.  A segment of the line con-taining the cursor is determined and displayed, and then corresponding segments of subsequent lines are determined and displayed.  Thereafter, a corresponding segment of the scale line is determined and displayed.  The display includes only whole characters adjacent its left edge.

Abstract: Abstract of the Disclosure There is disclosed a method of selectively plugging broken fibers included in a bundle of hollow fibers having open ends protruding from a tubesheet and closed ends distal from the tubesheet. The protruding open ends are immersed in a curable, fluid sealant and capillary attraction is utilized to draw the sealant into the broken fibers. The resistance to compression of the gases in the unbroken fibers is such that the sealant does not move into the latter fibers so far that they will not be open after the protruding ends are removed. The imbibed sealant is cured in place and the protruding fiber ends are cut off flush with the final surface of the tubesheet. This method is of particular value in preparing tubesheet-fiber assemblies for use in high temperature alkali metal-sulfur battery cells, wherein the hollow fibers function as an electrolyte-separator.

Abstract: ELECTROMAGNETIC CLUTCH DEVICE                 ABSTRACT OF THE DISCLOSURE         An electrogmagnetic clutch device for transmitting torque from an input means to an output means includes  a clutch actuating means in the form of an electromagnetic winding. The input means includes a driving plate coaxially disposed with and connected to an input shaft for rotation therewith, a driving friction ring member coaxial with the input shaft and connected to the driving plate for rotation with the input shaft and axial movement relative to the input shaft, and an armature coaxially disposed with and threadably connected to the friction ring member.  In response to the energization of the electro-magnetic winding, the friction ring member advances on the armature and into engagement with the output means for driving the output means.  A driving spring interconnecting the driving plate and friction ring member biases the friction ring member away from the output means to disengage the friction ring from the output means upon de-energization of the electromagnetic winding.  The relative rotational motion between the armature and the output means causes the armature to advance on the thread thereby allowing the friction ring member to fully engage with the output means.  The relative position between the armature and the driving friction ring member is maintained by a retarder disposed between the armature and driving friction ring which permits relative rotational motion between the driving friction ring member and the armature in one direction while preventing relative motion in the opposite direction.  The retarder also exerts an axial force on the threaded connection to the friction ring member and the armature.  In addition, a driving spring force reducer coacts with the driving plate and armature to bias the friction ring member toward the input means to compensate for the increased spring force exerted on the friction ring by the driving spring as the friction surface wears.
