Abstract: Methods and systems for electrochemically producing at least one product are disclosed. In some embodiments, the systems include a membraneless electrochemical flow-through reactor. A pair of porous electrodes configured at an angle to each other is disposed within the reactor in a channel of flowing electrolyte including a target reactant. As the electrolyte stream flows through the porous electrodes, a voltage is applied across the electrodes, resulting in the generation of a catholyte effluent stream and an anolyte effluent stream Gaseous and/or liquid products may then be separated from these streams. The membraneless electrochemical flow-through reactor is an easy to design and assemble apparatus for a variety of electrochemical processes.

Abstract: A torque monitoring system includes a rotatable measurement interface and a stationary data receiver. The measurement interface is configured to be attached to a rotatable shaft. The measurement interface includes a strain gauge, a processor, and a near field communication (NFC) transceiver coil. The stationary data receiver is stationary with respect to the rotating shaft. The stationary data receiver includes a processor and an NFC transceiver coil. The rotatable measurement interface receives operating power via its NFC transceiver coil that is derived from a radio signal wirelessly transmitted by the NFC transceiver coil in the stationary data receiver. The processor in the rotatable measurement interface is configured to receive strain gauge signals from the strain gauge indicative of torque on the rotatable shaft and wirelessly transmit digital data indicative of the strain gauge signals through the NFC transceiver coils to the processor in the stationary data receiver.

Abstract: A ninety degree snap fit electrical fitting for enabling rapid snap-fit insertion of an electrical cable to an electrical box. The ninety degree snap fit electrical fitting includes a connector body having a leading end, a trailing end, an internal bore, a box connection arrangement on the leading end, and a cable connection arrangement on the trailing end. A seat on the leading end of the connector body includes a snap ring with an outward extending locking tang. An internal snap ring is secured within the internal bore of the connector body at the trailing end. A cable retaining tang on the internal snap ring is adapted to engage and secure an electrical cable to the trailing end of the connector body.

Abstract: A duplex electrical connector constructed of two body portions with internal bores. The body portions easily assemble and disassemble in a sliding manner, the direction of the assembly and disassembly being substantially at right angles to the axes of the internal bores. A front connector body includes a leading end and a trailing end with a lip, a trailing flange, and a bottom periphery. A tab with an aperture therein extends from the top lip. A rear connector body includes a leading end with a front extension, a boss, a trailing end, and two internal bores extending from the trailing end to the leading end. Sliding assembly of the connector bodies enables minimizing the size of the connector bodies for reducing unit production costs while enabling easy disassembly of the two connector body portions for inspection of internal cable connections.
