Abstract: VACUUM CLEANER CONDITION INDICATOR AND SAFETY DEVICE     ABSTRACT OF THE DISCLOSURE    A vacuum cleaner detector that indicates when the hose is clogged and bleeds in cooling air to the vacuum chamber so as to prevent overheating of the motor blower.  The in-dicator comprises an actuator valve and a relief valve.          The actuator valve includes a pressure responsive member having filter bag compartment pressure applied to one side thereof and atmospheric pressure applied to the other side.          When the absolute pressure within the filter bag chamber drops, the pressure responsive member is moved toward the low pressure side moving a plunger which opens a port when the pressure drops below that desired to allow filter bag chamber pressure to vent to the low pressure side of a pressure responsive member in the relief valve.  The other side of the relief valve pressure responsive member is acted upon by atmospheric pressure which thereby forces the pres-sure responsive member away from a bleed hole to allow atmos-pheric pressure to flow into the filter bag chamber to insure that the motor blower has sufficient air flow for cooling, and simultaneously the pressure responsive member forces an in-dicator button out of the cleaner.  Also disclosed is a vacu-um cleaner filter bag condition indicator that detects when the bag is substantially full and should be replaced.  The use of the two indicators together allows the determination of whether the filter bag is full or whether the hose is clogged.

Abstract: Abstract of the Disclosure An oscillator provides an output signal of frequency f0, whose phase is shifted by substantially 45 to obtain a test signal which is coupled by a first cable to a bridge circuit located in proximity to a sample box and interconnected with an active center electrode of that sample box. In response to the test signal the bridge circuit provides a bridge output signal whose frequency is identical to that of the test signal and whose phase relative to that of the test signal and whose amplitude are related to the electrical admittance of particulate material within the sample box. The oscillator output signal is also applied to a phase-shifting network which provides first second third and fourth signals respectively in-phase, 90° out-of-phase 180 out-of-phase and 270 out-of-phase with the test signal. A switching circuit couples the first second third and fourth signals to its output in a predetermined sequence and at a frequency of fa, wherein f0 is much greater than fa, to develop a reference signal which is coupled by a second cable to a first input of a double-balanced mixer located in proximity to the bridge circuit. The bridge output signal is applied to a second input of the double-balanced mixer whereby a time-multiplexed mixer output signal is provided which has four successive DC levels proportional to positive and negative values of the conductance and susceptance components of the bridge output signal. The mixer output signal is coupled via the second cable and temperature and bulk density compensation circuits to first second third and fourth sample and hold circuits. The first and third sample and hold circuits store successive DC levels of the mixer output signal corresponding to positive and negative values of the conductance component and the second and fourth sample and hold circuits store successive DC levels of the mixer output signal corresponding to positive and negative values of the susceptance component. A first operational amplifier takes the absolute difference of the stored DC levels in the first and third sample and hold circuits to provide a first output signs proportional to the conductivity or the particulate material and a second operational amplifier takes the absolute difference of the DC level stored in the second and fourth sample and hold circuits to provide a second output signal proportional to the dielectric coefficient of the particulate material.
