The present invention provides a capacitive humidity transducer based humidity control system. The present invention comprises a humidity sensor, a temperature source for the heated cabinet air, a temperature source at the sensor, and a regulated water mist discharged into the cabinet air circulation system. An electronic system combines the input from the sensor, the temperature inputs, and the humidity percentage setting to regulate the timing and duration of the water mist discharge, thereby allowing to adjust percentage of humidity in heated holding cabinets. The sensor is a capacitor comprising two plates in close proximity but insulated from each other. The electrical output of the capacitor is sensitive to moisture on the surfaces between the plates. By cooling one plate until it reaches its dew point, the signal is detected and received by the electronic system. Cooling of the capacitor plate is accomplished by means of a thermoelectric cooler. When cabinet humidity falls below a predetermined threshold value and a corresponding change in capacitance of the capacitive sensor is detected, the humidity control system turns on a water mister to spray water into cabinet air flow until a desired relative humidity level is reached in the heated cabinet.

An improvement in a toggle bar for brachiation in place by the upper limbs for purposes of exercise and health, including an elongated tubular middle-section bar having a handle defining an enclosed opening mounted upon both ends. A J-shaped hook is mounted at the mid-section of the bar for reception of a suspended support whereby the bar is pivotally movable with respect thereto. In modification, a toggle bar wherein the entire bar is made from one continuous tubular bar.

Exercise bar

A system for locking either all or all but one of the drawers of a file cabinet. A bar rides in a groove at the interior of the shell of the cabinet. A plurality of drawer locks is engaged to the bar, each drawer lock including inclined and vertical surfaces at its rear edge. A rail having a key end is positioned at the side of each drawer so that the blunt end of the key faces the inclined surfaces of an associated drawer lock when all drawers are closed. The engagement of the blunt end with the opposed inclined surface of a lock raises the bar so that the blunt ends of the rail members associated with the remaining drawers abut and are locked by the vertical surfaces of the associated drawer locks. A block at the top of the bar abuts the cylinder of a cabinet lock when extended to prevent the vertical movement of the bar, locking all drawers.
