Abstract: A face shield adapted to fit over a face of a user to cover a nose and mouth of the user. The face shield includes an exhale port, an attachment system to fasten the shield to the user, a fan insert receiver, and an air inlet opening connected to the fan insert receiver. A fan that attaches to the fan insert receiver. The fan includes a motor, fan blades attached to the motor and an air exit. The air exit of the fan is positioned to dump air from the air inlet opening into the area covered by the shield. An air filter is connected to the air inlet opening of the shield. An exhale valve is connected to the exhale port that allows waste air to exit the shield. There is a power source connected to the fan motor to run the fan.

Abstract: A torque converter in which the standard one-way clutch, otherwise known as an overrunning brake, on the reactor, otherwise known as a stator, is replaced with a jaw clutch. When the jaw clutch is engaged, the reactor is non-rotate. When the jaw clutch is disengaged, the reactor spins freely. The jaw clutch can be placed on the same hydraulic fluid circuit as a bypass clutch.

Abstract: A method for on-the-fly detection and separation of multiple checks or like documents transported in a track, wherein the documents are first subjected to twin opposed vacuum forces from a suction source, to separate multiple documents; then a measuring and analysis of the resulting pressure differentials is taken within the vacuum-forming system; the system being provided with a cyclonic filter-separator upstream of the suction source, for removing a storing dust and debris entrained within the vacuum-forming air flow; the cyclonic filter-separator being designed to provide constant vacuum-forming airflow regardless of the nature or quantity of debris removed and collected; the system also being provided with a pressure sensor to give clear indication of the separated/unseparated state of the passing documents, and to exhibit a variable damping accessory.

Abstract: An apparatus for differentiating and separating multiple overlapped like documents from single like items, transported along a track comprising a suction device applying opposed vacuum forces to separate the documents at a separation station. Measuring and analyzing the resulting pressure differentials within the suction system by a pressure sensor to indicate whether single or multiple documents are passing.

Abstract: A method for differentiating and separating multiple overlapped like documents from single like items, transported along track means, comprising: subjecting the documents to opposed vacuum forces from suction means to separate them at a separation-station; then determining whether the documents are single or multiple, by measuring and analyzing the resulting pressure differentials within the suction system; using a cyclonic filter for removing and storing dust and debris entrained within the suction-conducting airflow, the cyclonic filter and suction system being designed and adapted to provide a relatively constant vacuum-generating airflow regardless of the nature of quantity of debris removed; plus a pressure sensor for indicating whether one or several documents are passing.

Abstract: In a check processing apparatus, a technique for separating multiple checks from single like items, these transported along a track wherein the checks are first subjected to twin opposed vacuums to separate them; their state (whether single or multiple) is then determined by measuring and analyzing the resulting pressure differentials within the vacuum-generating system; which is, in turn, provided with a cyclonic filter/suction pump for removing and storing dust and debris entrained within the vacuum-forming air flow, this cyclonic pump providing a constant vacuum-airflow regardless of the nature or quantity of debris removed and collected; the system being also provided with pressure sensor(s) to indicate whether (single or multiple checks are passing, plus a fail-safe unit to warn of vacuum failure. A pressure sensing unit is further provided with a variable damping stage to mask-out minor, insignificant pressure fluctuations.
