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.

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.

Double-document detection arrangement

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.

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.

Document separation/detection technique

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.
