Abstract: ABSTRACT          There is provided a stringed instrument in which an outer peripheral frame surrounds an open area, and in which a sounding board extends across the open area attached to the frame.  Anchoring means for strings are centrally located in the open area,   and pegs are dis-tributed around the edge of the frame.  Strings are provided between the anchoring means and the pegs, and due to the symmetrical nature of the structure, the high tension forces exerted by the strings on the center anchoring means are largely balanced out, so that particularly heavy bracing structure for the anchoring means is not required.          The instrument is suitable for being played by a plurality of players, approaching the instrument from several direc-tions, this being a departure from typical stringed instru-ments which are designed to be played only by one person at a time.

Abstract: Abstract of the Disclosure A fixed high frequency oscillator, variable frequency divider, and low frequency timer are provided to produce a high frequency output pulse group which is terminated at different intervals by both the variable frequency divider and the timer.  The characteristics of the frequency divider may be varied to produce a number of modes of generator operation, all of which utilize a single high frequency output.  The generator includes means for producing a voltage spike as one of the pulses of each output group with a crest ratio of at least 3:1 in the cut command group and at least 14:1 in the fulgurate mode.  The spike reionizes the current path through tissue without excessive tissue destruction due to wasted power and is minimized in dessicate mode where reionization arcing is undesirable.  A pair of opto-isolated hand-held switches allow the user to select continuously between two preset modes of operation without risking shock.

Abstract: COORDINATED CONTROL SYSTEM FOR AN ELECTRIC POWER PLANT     ABSTRACT OF THE INVENTION         The operation of an electric power plant is controlled by generating a control signal in response to the pressure at the throttle valves, the load demand signal and the megawatt output of the power plant.  During the start-up, before the pressure ramp ends, the control signal varies in accordance with the difference between the pressure at the throttle valves and the pressure required at the throttle valves to produce the load represented by the load demand signal and, after the pressure ramp ends, the control signal is varied in accordance with the difference between the load represented by the load demand signal and the megawatt output of the power plant.  Integral separators are employed during start-up to separate the water from the steam and a bypass system is provided to collect the water from the separators and recirculate it.  The firing rate of the furnace is controlled in accordance with the control signal.  After the bypass system has gone out of service, the feedwater pump is controlled in accordance with the control signal.  After the pressure ramp ends, the position of the throttle valves is controlled in accordance with the control signal.

Abstract: ABSTRACT        A control system is disclosed for connecting the primary windings of a three-phase AC induction motor in a delta-connection at heavy loads and for automatically reconnecting the windings in a wye-connection at light loads to effect energy savings.  A power sensor produces a control signal which is directly proportional to the power applied to the induction motor.  A differential comparator responds to the control signal and to an adjustable reference signal, representing a preselected power input level, for generating an actuating signal for switching a wye-delta starter between two conditions, one of which effects the wye-connection and the other the delta connection.  When the power input is below the preselected level the wye-connection is established, whereas the delta-connection is made when the power input is above the preselected level.

Abstract: ABSTRACT The invention relates to apparatus for analyzing electrical circuit boards.  Individual elements which have failed can be identified without disconnecting them from the circuit and testing may be done by unskilled operators by contacting a probe to a lead on an element.  The probe has at lease two contact elements close enough to each other to simultaneously con-tact a lead of a mounted integrated circuit, but spaced apart from each other sufficiently to permit measurement of electrical activity in the lead segment between the tips.  Circuitry is connected to the probe for measuring the voltage drop between the two tips resulting from the flow of test current through the resistance of the lead segment, which current flow is indicative of the condition of the element.

Abstract: ABSTRACT OF THE DISCLOSURE        A slack adjuster for axially moved push rods is provided.          An axially extending rotating actuating shaft turns a helical, driving cam member that in turn axially displaces a non-rotating driven cam member.  The driving and driven helical cam members are located in a housing with the actuating shaft extending out of one end thereof and a threaded push rod extending out of the other end of the housing.  A helical return spring is positioned between the driven cam and the inner wall of the housing to bias the cam members together.  The push rod is held against rotation intern-ally of the housing by a flange whose periphery is frictionally engaged by the return spring.  A nut is threaded onto the rod and engaged by the driven cam member to transmit axial force to the push rod; and relative extension of the push rod from the cam members is accomplished by a one way spring brake acting on the nut and a disc clutch drive between the driving cam and nut.  Lost motion is provided to prevent rotation of the nut on the rod during normal push rod clearance, and rotation of the nut on the push rod occurs when excessive push rod clearance occurs.

Abstract: ABSTRACT OF THE DISCLOSURE          Lighting apparatus for independently controlling the lighting level in several areas or zones.  For example, each zone has two fluorescent lamp units, one connected between the power lines through the contacts of a first low voltage AC latching relay, and the other which produces about half the light of the first connected between the power lines through the contacts of a second relay.  Each relay has three terminals.  When a low voltage AC signal is applied between a first terminal and a common terminal, the relay is latched closed; and when a low voltage AC signal is applied between a second terminal and a common terminal the relay is latched open.  The common terminals of the two relays or each zone are connected together to provide enable connections identifying each zone.  The first terminals of all the first relays are connected together, the first terminals of all the second relays are connected together, the second terminals of all the first relays are connected together and the second terminals of all the second relays are connected together to provide four data connections.  By applying momentary low voltage AC signals between appropriate data and enable connections, any desired combination of lamps can be turned on or off.
