Abstract: A tandem polyolefin depolymerization-metathesis process and system for converting polymer waste to smaller hydrocarbons, specifically liquid and gaseous products, which subsequently can be modified and used as feeds or co-feeds for making circular products such as circular ethylene and polyethylene. Specifically, the disclosed processes include a tandem depolymerization process step followed by a metathesis process to provide a effluent that can be separated, further processed with a subsequent depolymerization step, or both. The effluents can be supplied to downstream processing units such as a steam cracker or AROMAX® unit thereby providing an efficient method for converting polymer waste into useful circular products. Therefore, these processes and systems can expand the number of usable plastic waste streams and improve the economics of plastic waste recycling.

Abstract: Conventional devices deliver a degree of electrical charge into biological tissues; —to satisfy regulatory and safety concerns, measures are taken to maintain a zero-charge residual at the stimulation site. Disclosed herein is a method of controlling electrical energy provided by a stimulation device to one or stimulation electrodes comprised in the device, the device including: a first stimulation electrode; a pulse energy controller for transferring electrical energy as one or more electrical stimulation pulses to the first stimulation electrode; the pulse energy controller further including two or more stimulation energy supplies for each supplying electrical energy substantially concurrently to the first stimulation electrode as a first pulse; and each supplying electrical energy separately to the first stimulation electrode as a second pulse.

Abstract: A method of identifying a selected pollination window in a Poaceae crop by monitoring one or more environmental parameters and identifying a selected pollination window based upon the monitored parameters. The correct selection of parameters has been shown to markedly increase seed set, yield, and/or other desirable characteristics, including but not limited to preferred content of oil, starch, protein, and/or other nutritional components. Parameters may include one or more of: temperature, relative humidity, and vapor pressure deficit.

Abstract: An Environmental Control System may use an electronic air treatment system to control humidity in an aircraft. The electronic air treatment system may use an electronic charging system and a separation system. A turbine rotor may drive a power generating stage to provide high voltage power to the electronic charging system. The charging stage may charge airflow passing through to repel liquid particles away from the airflow. Liquid droplets may be collected and centrifugally flung toward a periphery of the separation system. The liquid particles may be collected outside of the airflow, which may be allowed to pass through the separation system and out to a destination in the aircraft without the collected liquid.

Abstract: A turbomachine having gas cooled bearings may include an axially-oriented, cooling-gas passageway interconnecting first and second bearing chambers. The passageway may include grooves formed at an interface between an aerodynamic component of the turbomachine (e.g., a wheel or impeller) and a portion of a shaft assembly of the turbomachine.

Abstract: A compressor ported shroud takes compressed air from the shroud of the compressor before it is completely compressed and delivers it to foil bearings. The compressed air has a lower pressure and temperature than compressed outlet air. The lower temperature of the air means that less air needs to be bled off from the compressor to cool the foil bearings. This increases the overall system efficiency due to the reduced mass flow requirements of the lower temperature air. By taking the air at a lower pressure, less work is lost compressing the bearing cooling air.

Abstract: A method for manufacturing a rotor assembly. The method includes providing a stub shaft having a first part and a second part, providing a magnet between the first part and the second part, and compressing the magnet between the first part and the second part using a connecting device. The method also includes drilling a hole through the first part and the magnet, cooling an inner shaft, and inserting the inner shaft into the hole.

Abstract: This invention introduces a new concept called virtual construct intervals (VCI), where each predicate interval is decomposed into one or more of these construct intervals. These VCIs strictly cover the predicate interval. Namely, every attribute value covered by the predicate interval is also covered by at least one of the decomposed VCIs, and vice versa. Each construct interval has a unique ID or interval coordinate and a set of endpoints. A construct interval is considered activated when a predicate interval using it in its decomposition is added to the system. The predicate ID is then inserted into the ID lists associated with the decomposed VCIs. To facilitate fast search, a bitmap vector is used to indicate the activation of VCIs that cover an event value. The challenge is to find an appropriate set of construct intervals to make predicate decomposition simple and, more importantly, to build efficient bitmap indexes.

Abstract: A fuel cell system comprises a compressor and a fuel processor downstream of the compressor. A fuel cell stack is in communication with the fuel processor and compressor. A combustor is downstream of the fuel cell stack. First and second turbines are downstream of the fuel processor and in parallel flow communication with one another. A distribution valve is in communication with the first and second turbines. The first and second turbines are mechanically engaged to the compressor. A bypass valve is intermediate the compressor and the second turbine, with the bypass valve enabling a compressed gas from the compressor to bypass the fuel processor.
