Abstract: ABSTRACT OF THE DISCLOSURE A novel sponge mop is provided herein.  The sponge mop includes a hollow body of elongate tubular configuration; an operating handle adapted for axial reciprocation within the body between a working posi-tion and a water wringing position, the handle endwardly carrying a sponge assembly connector means, the sponge assembly connector means comprising a cylindrical, axially aligned fastener means downwardly projecting from the handle; a sponge squeezing assembly affixed at one end of the hollow body, the sponge squeezing assembly comprising at least a pair of spaced rollers to wring water from the sponge; and a sponge assembly releasably connected to the sponge assembly connector means and comprising a sponge, a sponge carrier and engagement means to engage the sponge assembly fastener means, the engagement means com-prising a threaded nut secured to the sponge carrier, the nut releasably engaging the fastener means, at least major portion of the sponge being pulled between the rollers to drive water from the sponge when the operating handle is reciprocated to its water wringing position.  In this construction, all necessary upwardly directed forces required to wring water from the sponge or downwardly directed forces to expose the sponge below the rollers for cleaning action are axially applied by the reciprocating handle within the hollow body.  All forces necessary for sponge wringing purposes are applied directly in axial alignment whereby the reciprocation of the sponge above and below the rollers can be accom-plished with minimum forces in a fully balanced manner, thereby to assure most efficient application of force.  The simplified wring means design requires the utilization of only a minimum number of operating parts.

Abstract: A B S T R A C T             CHARGE BALANCE VOLTAGE-TO-FREQUENCY CONVERTER                       UTILIZING CMOS CIRCUITRY       A  charge balance voltage-to-freqency converter utilizes CMOS circuitry to provide a digital pulse output proportional to an analog input signal. The converter approaches a desired charge balance by cycling between a charging and a discharging state. A clock signal provided by a stable oscillator is applied to a clock input of a CMOS          D-type flip-flop. The analog input signal effectively is fed to a non-inverting input of an integrating amplifier. The output of the integrating amplifier is fed to the D input of the flip-flop, which input has  a threshold level.   The Q output  of  the  flip-flop  is connected  via  a  voltage  divider  to an  inverting  input  of  the integrating amplifier.  This configuration eliminates the need for a dual  polarity  power  supply.   When  the  output  of the integrating amplifier rises above the threshold level of the D input, on the next rising edge of the clock signal, the flip-flop sends feedback pulses to the inverting input,  thus beginning  the discharge state.   Each feedback  pulse  causes  the  integrating  amplifier  to  discharge  a predetermined amount.  When the output of the integrating amplifier falls below the D input threshold level feedback pulses are inhibited, and the charging state begins again. The output pulses from the flip-flop, when accumulated over a period of time, represent the charge required to balance the charge provided by the input signal. The feedback pulses are summed by an accumulator to provide an indication of the converter input.
