Abstract: ABSTRACT OF THE DISCLOSURE        A rotating electric machine comprising a stator and a rotor which is adapted to be rotated about an axis and which is disposed opposite said stator.  Normally, the magnetic field of the rotor is excited by a direct current which is supplied via sliding contacts.  In order to avoid wear of the sliding contacts, the invention employs the measure that the exciting current for the magnetic field of the rotor is supplied via a second stator and a second rotor by means of induction.

Abstract: POWER SAVER CIRCUIT FOR AUDIOVISUAL SIGNAL UNIT     ABSTRACT A combined audio and visual signal unit with the audio and visual components actuated alternately and powered over a single cable pair in such a manner that only one of the audio and visual components is drawing power from the power supply at any given instant. Thus, the power supply is never called upon to provide more energy than that drawn by the one of the components having the greater power requirement. This isparticularly advantageous when several combined audio and visual signal units are coupled in parallel on one cable pair. Typically, the signal unit may comprise a horn and a strobe light for a fire alarm signalling system.

Abstract: ABSTRACT OF THE DISCLOSURE           Undulations in rear side of tag, such as alternating ribs and troughs, permit air flow to area around stem of pin having conical head or point.  Pin has a soft plastic base attached to stem opposite conical point and a hard plastic button larger than head of pin, surrounded by soft plastic.  Pin stem has groove at button, which has holes and convex undersurface. Applicator has opposed arms on pivoted handles, one arm having a laterally enlarged platform with a rim on both sides and at rear, the latter to position the pin base longitudinally.  Spring clip engages pin base and has slot to laterally position pin stem.      Opposite arm has rimless surface engaged by tag head, to permit different angular tag positions, for about 260 degree. Longi-tudinal notch is opposite rimless surface and permits pin head to pass through during installation, while ledge around notch abuts end of socket and perpendicular wall, around ledge, positions tag head in alignment with pin.  Platform on one arm and rimless surface on the other arm are divergent with respect to pivot axis of arms prior to installation but convergent when arms are moved to closed position.

Abstract: JEWELRY CLUTCH Abstract of the Disclosure A clutch is disclosed consisting of two parts, the first part being a tubular shell closed at one end, the shell having therein a resilient female clutch member that is held in position by lips on the open end of the shell. A male member is provided which is adapted to be received within the resilient member.  The resilient member within the shell is cylindrical of a longitudinal dimension less than the space within the shell and of an outside diameter less than the inside diameter of the shell.  The male member is made of a size so that the sum of its diameter plus the wall thickness of the resilient clutch member is greater than the inside diameter of the tubular shell, so as to cre-ate an airtight joint when the male member is inserted within the resilient member, but yet permitting air to escape around the outside of the resilient member and retarded only when disengagement is attempted  at which time the resilient clutch member will seal against the lip of the tubular shell.

Abstract: ABSTRACT     A sputtering cathode apparatus for the deposition of thin films which are produced at a relatively high deposition rate.  A relatively large planar maynetron sputtering system or apparatus is provided with a preferred single convoluted electron path so as to obtain high geometric efficiency.  The target is larger than the substrate and the substrate motion is confined to an area within the defined target area.  The cathode system requires a vacuum system of relatively small dimension due to the increase in target size in comparison with substrate size along with the provision for multiple plasma legs separated by non-emissive regions therebetween.  This construction enables minimized substrate motion relative to the target.

Abstract: ABSTRACT OF THE DISCLOSURE A new process is provided for producing highly resilient, textured, continuous multifilament polymeric yarns and combinations of such yarns with other continuous filament yarns and with spun yarns. The unstable or wild loops which form in conventional air jet textured yarns are substantially eliminated in the product yarns of this invention. The product yarns are formed by continuously drawing polymetic yarn under controlled temperature conditions, texturing the yarn in an air jet texturizer and subjecting the textured yarn to saturated steam while restraining the linear shrinkage of the yarn in the presence of the steam, followed by continuous take-up of the yarn on a package.

Abstract: Abstract of the Disclosure A no-load missile restraint arrangement for releasing a rocket propelled missile promptly after ignition of its rocket motor, and the expulsion of a nozzle seal from its rocket motor nozzle.  An anchor device extends from the aft end of the missile, which is engaged by the nose portion of a pivotable latch member.  The latch member has two operative positions, with the nose portion engaging the anchor device until the sea is driven rearwardly at the time of ignition of the rocket motor.  An elongate device operatively associated with the latch member is struck by the rapidly moving seal, bringing about the releasing of the latch member such that it can pivot to an anchor-releasing position.  In this way the missile is released prior to any substantial buildup of thrust in the rocket motor.
