Abstract: A laundry ozone injection system includes an ozone generator connected to an ozone distribution manifold having a plurality of manifold outlets connected through ozone valves to ozone injectors associated with washing machines of a laundry plant. Each washer has water cycled therefrom by a pump, through the ozone injector, and back to the washer chamber. A washer cycle controller of each washer is interfaced to a local interface module along with a pump motor. The local interface modules are interfaced to an ozone distribution controller or main controller which is also interfaced to the ozone valves. The current washer cycle of each machine is detected by its local interface module and communicated to the main controller which controls the rate of ozone production of the ozone generator, the activation of the pump motor, and the opening of the ozone valve of a washer in accordance with the currently detected washer cycle to thereby control the delivery of ozone to the washer.

Abstract: The invention includes an apparatus for and method of moving textile articles such as pieces of laundry or the like comprising an enclosed passageway having two opposing open ends, and at least one bend between the two open ends; a vacuum source coupled with one of the two open ends and developing a subatmospheric pressure along the passageway and at the other open end of the passageway to draw textile articles into the other open end and through the passageway to the one open end; and a sensor located at the one bend and sensing textile articles drawn through the passageway. The sensor is coupled with an appropriate counter for accumulating a count of successive textile articles drawn through the passageway. A delay circuit is included between the sensor and the accumulator to inhibit successive detector outputs for a selectable but fixed time period, regardless of the size of the textile articles being passed and counted.
