Abstract: An airflow test device designed to be used in a clothes dryer. The device includes a retainer which is mounted to an outlet grate of the dryer drum. A vent card is removably supported a predetermined distance from the outlet grate by a support finger extending from the retainer. The vent card is supported in such a manner that a predetermined rate of airflow through the outlet grate during dryer operation moves the vent card toward the outlet grate. Movement of the vent card toward the outlet grate and off the support finger during clothes dryer operation signals that an adequate rate of airflow is passing through the outlet grate.

Abstract: A liquid sight monitor includes a translucent thermoplastic viewing tubular element having ends that are flared, after the tube is inserted through the central holes of flanges located at either end, to secure the viewing element in place. A float may be included in the viewing element of the same material and cup shaped to entrap air so that the float rises to the level of the fluid surface, even though it is otherwise heavier than the fluid. A flow-through restrictor disk prevents the float from falling out the bottom of the viewing element when there is an absence of fluid therein. The monitor may have a protective see-through shield connected between its top and bottom flanges, if desired.

Abstract: A combined idler assembly and belt failure switch for a dryer is provided in which the idler assembly is mounted directly to the motor end bell for ensuring precise alignment of the assembly and a centrifugal motor switch is utilized to perform an additional function of terminating dryer operation upon breakage of the drive belt.

Abstract: A clothes dryer with a non-circular front access opening is provided with a split ring bearing attached to the dryer drum in a manner to allow for expansion and contraction of the bearing relative to the drum and which rides on a support ring which is attached to and conforms to the access opening, thereby providing a front support for the drum.

Abstract: A liquid sight monitor including an internal sight tube surrounded by an external sight tube, the ends therebetween being spaced apart by inserts including "O" rings sealing against both tubes. The internal annulus between the tubes can be environmentally purged. A protective shield can be provided, which also provides mounting flanges for supporting the overall apparatus in position for metering the system.

Abstract: A device for the purpose of providing computerized direction and control in the process of manually sorting documents. A sorting bin is provided containing compartments into which documents are placed to effect the sort. The sorting bin is contained within a sorting console which also houses a power supply; an indicator and document detector array; a control unit which monitors the document detectors, operates the indicators, and communicates with a computer; and control switches and indicators.An operator sorts documents by depositing them one at a time into a selected compartment of the sorting bin. The control unit, under computer direction, indicates to the operator the correct compartment for depositing each document, by illuminating indicators associated with the proper compartment. Document detectors inform the control unit when a document is deposited in any compartment. When a document is deposited in an incorrect compartment, an alarm alerts the operator.
