Abstract: A transport system with curved track pair is constructed for multiple pulsed X-ray source-in-motion to perform fast digital tomosynthesis imaging. It includes a curved rigid track pair with predetermined curvature, a primary motor stage car loaded with X-ray sources and wheels loaded with tension or compression springs. The car is driven by primary motor mounted at base frame and an engaged gear mounted at the car. The car can carry heavy loads, travel with high precision and high repeatability at all installation orientations while motion vibration is minimal. It is also scalable to have a larger radius. Track angle span usually can be from about ten degrees to about 170 degrees. During imaging acquisition, X-ray sources can sweep precisely from one location to another. The car has enough clearance to move in its path without rubbing wheels on tracks. Better than 0.2 mm overall spatial precision can be achieved with the digital tomosynthesis imaging.

Abstract: A turboexpander can operate as a microgrid electric generator for islanding operations. The turboexpander can recover energy lost during a pressure letdown sequence to generate electricity. Pressurized process gas can cause a turbine to rotate, thereby rotating a rotor within a stator of the turboexpander. A power electronics can include an islanding mode inverter to output an alternating current that comprises a frequency and an amplitude compatible with powering a load. The power electronics can include a battery that is charged by the turboexpander and can provide power for starting up the turboexpander. The power electrics can include a bidirectional inverter to send excess power from the turboexpander to a power grid and to receive power from the power grid for start-up.

Abstract: When a drive unit 5 drives to rotate a first rotator 6 and a second rotator 7 relative to one another in a first relative positional relationship R1 toward one side, graspers 8 turn toward the one side to cause respective pawl portions 8c to advance into a detachment operation space S1 such that the pawl portions 8c can contact an electrode 10 set in the detachment operation space S1, and when the drive unit drives to rotate the first rotator 6 and the second rotator 7 relative to one another in a second relative positional relationship R2 toward another side, the graspers 8 turn toward the other side to cause the respective pawl portions 8c to advance into the detachment operation space S1 such that the pawl portions 8c can contact an electrode 10 set in the detachment operation space S1.

Abstract: A tool changing mechanism includes a tool base housing, a mandrel disposed therein and having a chamber and a keyway provided axially, and first and second linked units. A first shoulder portion is provided at an end of the keyway, and pulling jaws are disposed at the other end. The first linked unit has a first pulling rod, an end of which has an external thread, and the other end has a connecting portion driven by a pneumatic cylinder. The second linked unit has a second pulling rod, an end of which has an internal thread, and a pressing head is disposed at the other end. The second pulling rod has a sliding key located in the keyway. The first pulling rod is screwed into the second pulling rod, and the relative screwing rotation therebetween attains tool pulling for fixing or tool loosening for removing the cutting tool.

Abstract: An integrated circuit includes a flip-flop circuit and a gating circuit. The flip-flop circuit is arranged to receive an input data for generating a master signal during a writing mode according to a first clock signal and a second clock signal, and to output an output data according to the first clock signal and the second clock signal during a storing mode. The gating circuit is arranged for generating the first clock signal and the second clock signal according to the master signal and an input clock signal. When the input clock signal is at a signal level, the first clock signal and the second clock signal are at different logic levels. When the input clock signal is at another signal level, the first clock signal and the second clock signal are at a same logic level determined according to a signal level of the master signal.

Abstract: The present invention discloses a multitype-adsorptive-group polycarboxylic acid water-reducing agent, consisting of 30-60 wt % of a macromolecule with multitype-adsorptive groups and water, the macromolecule with multitype-adsorptive groups has a polyethylene glycol side chain, and adsorption groups of the polymer backbone include a carboxylic acid group, a sulfonic acid group and a phosphoric acid group, the phosphoric acid group being linked to the backbone of the macromolecule with multitype-adsorptive groups by nucleophilic addition. The water-reducing agent of the present invention has significantly improved adaptability to different cements and aggregates while maintaining a high water reduction efficiency, compared with the conventional polycarboxylic acid water-reducing agent agent. It has a good water reducing efficiency in many different grades of cement, as well as a better resistance to aggregates containing more impurities such as machine-made sand.
