Abstract: ABSTRACT OF THE DISCLOSURE         A method of static reactive power compensation is disclosed wherein the system voltage is compensated by supply-ing advanced-phase or retarded phase reactive power in dependence upon the difference between the system voltage and a reference voltage.  The difference is formed by a comparator  which receives a variable reference voltage from a filter containing a time lag circuit and which receives the system voltage as an input.  For transients, the output of the filter does not change and thus reactive power is applied.          For smooth variations, the output of the filter follows that of the system voltage so that the output of the power com-pensation circuit is maintained at zero.

Abstract: ABSTRACT          "Proximity Switch Circuit"                (Fig. 1) The circuit operates a main switch SCR to pass an a.c. supply V through a load L when a metallic object is in proximity to coil L1.  Coil L1 is driven by an oscillator comprising transistor T2 and associated components.  SCR is gated on simultaneous occurrence of an output from level detector T3 and a signal from T5, these being ANDed by T4.     The timing of the signal from T5 in the supply cycle is governed by the RC time constant of C4,Z1,R14 and is such that the power supplied to the oscillator and level detector is the minimum necessary, for a wide range of supply voltage and load current.

Abstract: ABSTRACT OF THE DISCLOSURE           A rotatable film wrapping apparatus for wrapping a load on a conveyor with an overwrap of stretched plastic film web, having a film web pre-stretching mechanism which is provided with a constant torque by a power assistance mechanism.  The power assistance mechanism comprises a stationary ring adjacent a rotary ring on which the film roll and pre-stretch mechanism are mounted, and a  friction roller on the rotary ring which contacts the stationary ring to transfer rotational energy to the pre-stretch device as the rotary ring rotates.  The pre-strech mechanism comprises a downstream roller across which the film is drawn to the load at a speed which varies, and an upstream roller linked by gears to the downstream roller so that the upstream roller rotates, at a fixed fraction of the speed of the downstream roller to stretch film between the rollers. The energy of the friction roller is transferred through an adjustable constant torque device to the pre-stretch mechanism without controlling the speed of the pre-stretch mechanism, and since a constant torque is added to the pre-stretch mechanism, the the force on the film to the load can be substantially reduced while allowing the pre-stretch drive to speed up and slow down according to the film demand from corners or changing load size.  This permits higher levels of stretch, faster payout speeds, and use of less uniform film than were thought possible previously.  Relatively centered loads with minimum corner protrusion may be wrapped without the constant torque device by a proper selection of gears such that the downstream roller surface speed is driven slightly below the average relative surface speed of the load.

Abstract: Elevator Control Abstract An operational controller is located in the elevator car, and a mobile transceiver, also located in the car, is connected to the operational controller, which includes a microprocessor that controls the transceiver.  A stationary transceiver is located in the lobby, and the two transceivers are connected over two pairs of wires in the traveling cable.  These transceivers communicate by dual tone combinations, each combination identifying a hall button, a hall lantern, and a position indicator in the lobby.  When the hall button is depressed, to place a call, the stationary transceiver provides a dual tone signal over one pair of wires to the mobile transceiver.          When the call is registered, the mobile transceiver echoes that signal back over the other pair of wires.          The stationary transceiver activates the light asso-ciated with the button and blocks out the connection between the button and the transceiver to prevent further production of the signal.  The mobile transceiver provides a dual tone signal to the stationary trans-ceiver which decodes it to activate the proper numeral in the position indicator.  When a service request is answered, the echo signal is again supplied to the stationary transceiver, but along with a D.C. level shift in the wire pair carrying it.  The stationary transceiver in response to both deactivates the light associated with the button identified by the echo signal.  The mobile transceiver also provides a dual tone signal which identifies the lantern on the floor, and the stationary transceiver decodes that signal to activate that lantern.

Abstract: ELECTRICAL SWITCH MECHANISM                        Abstract An electrical switch mechanism which operates in response to deceleration or acceleration for use on on board trains for brake assurance purposes.  High sen-sitivity to deceleration or acceleration with low hys-tereisis is obtained by actuating a switch, when a pendulum swings a predetermined distance, through a force transfer system providing a mechanical advantage enabling a pendulum of reasonable size and mass to actu-ate commercially available switches which require appre-ciable actuating force.  The motion of the pendulum is damped by an eddy current damper having a plurality of magnets establishing a magnetic field which alternates in direction along the path traversed by a vane of con-ductive material carried by the pendulum to reduce over-swing in response to acceleration or deceleration, to reduce pendulum response to high frequency components of the acceleration and deceleration and help in preventing transient motion of the pendulum which might arise from other than deceleration or acceleration events which are to be detected by the switch mechanism.
