Abstract: ABSTRACT OF THE DISCLOSURE           A multibladed helicopter rotor carries at least three bifilar absorbers which are tuned to eliminate in-plane vibrations of the rotor that otherwise would be transmitted to the helicopter fuselage.  By drooping the radial support arms for the absorbers out of the plane normal to their axis of rotation, the resultant of the centrifugal forces acting on the pendulous elements of the absorbers and the weight of these elements acts normal to the axes of the tuning pins of the absorbers which minimizes internal frictional damping in the absorbers.

Abstract: TEMPERATURE COMPENSATED SURFACE ACOUSTIC                     WAVE OSCILLATOR                          ABSTRACT      Disclosed apparatus compensates for the parabolic temperature induced frequency drift characteristic of a surface acoustic wave tuned oscillator.  The apparatus in-cludes a pair of varactor diodes and a temperature sensitive voltage supply.  The diodes are series connected and coupled in circuit with the oscillator to affect the frequency thereof.  The voltage supply connects to the common connec-tion of the diodes, for producing control voltages thereat.    Each varactor diode is chosen to have a .delta. > 1; and the control voltage varies linearly with temperature.  This results in a varactor diode capacitance versus temperature characteristic which is a continuous, true parabolic function providing precise compensation for the thermal drift of oscillator frequency.

Abstract: ABSTRACT          A pneumatically operated rotary power slip assembly which is mountable in a rotary drilling table.  It includes a stationary housing having an axially extending opening therethrough adapted for mounting generally coaxially with the pipe opening in the rotary table.  The stationary housing has a conduit therein for transmitting pressurized fluid.  The assembly includes a rotary housing having an axially extending opening therethrough, which housing is adapted for mounting generally coaxially with the opening in the rotary table and for rotation therewith.  The stationary housing is provided with a pair of inflatable annular seals which, together with the rotary housing, form two axially spaced apart annular ducts between said housings upon inflation of the seals.  The rotary housing supports at least one generally radially extendable and retractable slip, which slip is arranged to engage a pipe inserted through the rotary housing in the radially inwardly extended position and for releasing the pipe in the radially outwardly retracted position.  At least one pneumatic cylinder is mounted in the rotary housing and arranged for moving the slips radially inwardly and outwardly upon actuation thereof.  Additional conduits are provided in the rotary housing for communication with each of the aforesaid ducts and transmitting pressurized fluids to the pneumatic cylinder for operation of the aforesaid slips.  The apparatus includes valve means for controlling alternate flow of fluids through the ducts to control operation of the pneumatic cylinder to move the slip radially inwardly and outwardly.  There is thus provided a rotary power slip assembly which is removably inserted in a rotary drilling table wherein the pneumatic cylinder rotates with the slips such that the slips can be positioned in any position around the full circumference of the opening through the drilling table.  The seal arrange-ment for transmitting fluid pressure to the pneumatic cylinder permits operation of the cylinder in any position as aforesaid.

Abstract: ABSTRACT           Alternate-twist plied yarns, wherein a secondary strand for providing a special effect is plied with at least two alternately, false-twisted primary strands, are made by converging the secondary strand with the primary strands downstream of the point at which the primary strands are converged.  Node centers at the twist reversal points for the secondary strand are displaced with respect to node centers of the primary strands.  Improved effectiveness from an antistatic secondary strand in the plied yarn can be obtained by this method.  Where a node of a secondary strand overlaps a node of the primary strands, whether or not the node centers are displaced, a preferred configura-tion is one wherein the secondary strand forms a node by wrapping around only one of the primary strands in a portion of the primary node.

Abstract: ABSTRACT OF THE DISCLOSURE    An electrical socket and associated circuitry is provided wherein current can flow to the socket only when a load device is in the socket and a normally open, momentary "make" switch is closed.  The circuitry includes a relay for actuating a switch in parallel with the momentary make switch, which relay is energized upon closure of the momentary make switch and remains energized so that current will continue to flow to the socket until a normally closed, momentary "break" switch is opened.          Current cannot flow through the socket with the load device re-moved even if one should touch the socket except in the unlikely event the make switch is closed.  Several embodiments are disclosed wherein no current can flow through the socket unless at least three socket parts are engaged.  In one form of socket, the socket base contact is divided into two parts, both of which must be engaged in order for the relay to remain energized.  In another form the socket shell contact is divided into two parts and again both parts must be engaged for the relay to remain energized.  Other sockets are illustrated wherein the presence of a load device is sensed by switch means which may include the socket base contact. Circuits for use with polarized plugs are disclosed and a form of circuit for use with an unpolarized plug is also dis-closed.  Further, a circuit utilizing a rectifier and a low voltage relay is also disclosed wherein the make and break switches are in low power lines.
