Abstract: 26                48, 380 ABSTRACT OF THE DISCLOSURE A dynamic stabilizer of the type which is util-ized to compensate or stabilize the effect of subsynchro-nous resonance oscillations in a turbine generator system is taught.  Silicon controlled rectifiers are connected in series with inductors between the lines of the electrical system.  The silicon controlled rectifiers may be main-tained at two quiescent conduction intervals of 90° and 135° depending upon the peak value of rotor oscillation. If the peak value of rotor oscillation is sufficiently small the lower conduction interval of 90° is utilized as this is sufficient to stabilize low level oscillations. Furthermore, it has great advantage in the fact that the losses represented by 90° quiescent conduction interval are relatively small when compared with the larger quies-cent conduction interval.  If on the other hand the gener-ator speed peak oscillations become very large necessita-ting extended dynamic range for the stabilizer the quies-cent conduction interval is changed automatically to 135°. This  provides  the needed dynamic  range.   A short time after the circuit has been stabilized in this region the circuit  is  automatically  returned  to  a disposition  in which the minimum conduction angle is utilized.

Abstract: ELECTRICAL CONNECTOR ATTACHABLE              TO AN END PORTION OF A POWER CABLE     ABSTRACT OF THE DISCLOSURE     An electrical connector having a tubular support through which a power cable extends, and a contact housing within which the cable is connected to male or female contacts.          The support and housing have mating quick threads facilitating their assembly after connection of the cable to the contacts. A lock means on the support automatically responds to connection of the support and housing to each other, to prevent their accidental separation.  Normal operation of a cable clamping device on the support clamps and strain-relieves the cable within the support.  Deformation of the cable to offer strain relief acts upon the lock means to prevent its movement from the position in which it locks the housing and support against accidental separation.  A cable-clamping and strain-relieving device is disclosed, including a screw threadable laterally through an opening of a wiring device body into a power cable-receiving passage formed in the body.          A swiveled head on the screw bears against the insulation of the conductor.  Through the provision of guide slots in the body in which the screw is mounted, the head is maintained against rotation during advancement of the screw and removal of the screw from the body is prevented.

Abstract: ROLLER SUPPORT FOR CAGE SWEEP MECHANISM                ABSTRACT OF THE DISCLOSURE         The reciprocating cage sweep mechanism (26) for an axial flow rotary combine is supported by grooved self-lubricating plastic rollers (46) running on a pair of parallel support rods (42, 43).  The bottoms of the grooves (81) of the rollers (46) are spaced from the rod surface to permit a squeezing action to occur as deposits of crop material and dust build up on the surface of the rod (46).  The squeezing action causes the deposits to be extruded rather than compacted on the rod surface.  Thus, the buildup of deposits on the rod (46) are reduced.  The rollers (46) are individually supported on the reciprocating cage sweep carriage (41) by nonrotatable shafts (71) each of which has a spiral recess (74) in its cylindrical bearing surface (73).  The spiral groove (74) induces egress of dust and other fine particles from between the complementary cylindrical bearing surfaces (78, 74) of the roller (46) and its shaft (71).

Abstract: ABSTRACT OF THE INVENTION The present invention relates to an apparatus for accepting or rejecting a single type of coin, which is designed and constructed only to accept genuine coins of a particular value or denomination, and to reject spurious coins or slugs which may have the same dimen-sions. The present invention also provides an auxiliary coin acceptor-rejector component or device which may readily be fitted into already existing coin operated devices so as to discriminate more accurately between genuine coins and spurious coins or slugs. In such apparatus a sensing coil is provided for discriminating between genuine and non-genuine coins by suitable cir-cuitry to actuate an accept solenoid to receive a genuine coin in an accept slot and to direct all other non-genuine coins to a reject slot. To discriminate between genuine and non-genuine coins two parameters are utilized. The first parameter provides discrimination by means of the current being proportional to voltage drop and the second parameter provides discriminations by a frequency shift, both of such discriminations being detectable when the coin passes through the sensing coil.
