TL;DR: In this article, a transformer having a primary connected in series with a switch and storage device and a secondary connected with the load and a monitor circuit develops an output signal indicative of the load voltage and current.
Abstract: A pulse forming network or capacitor load is charged to a precise voltage from an energy storing device with a circuit including a transformer having a primary connected in series with a switch and storage device and a secondary connected in series with the load and a monitor circuit. The monitor circuit develops an output signal indicative of the load voltage and current. In response to the output signal increasing to a predetermined value the switch is opened. The transformer, having a substantial leakage inductance, releases its stored energy when the switch is opened. The transformer stored energy is coupled to the load and to a capacitor connected to the primary. Charge stored in the capacitor after the load requirements have been satisfied is transferred back to the energy storage device.

TL;DR: The structure of tetramethyl-1,3-bis(trimethyl-siloxy)distannoxane is known from X-ray analysis as discussed by the authors, and the proton magnetic resonance spectra of this compound demonstrates that its dimeric nature is preserved in solution.

TL;DR: In this paper, direct aqueous injection is used for the rapid screening of trihalomethanes and other volatile organic compounds (VOC's) in water by direct on column injection of the water sample in to wide bore capillary columns, to which is attached an electron capture detector.
Abstract: The disinfection of drinking water with chlorine produces carcinogenic by-products called trihalomethanes or (THM's). These compounds are formed when the chlorine reacts with the organic matter in the raw water. The four major THM's are chloroform, bromodichloromethane, dibromochromethane, and bromoform. Direct aqueous injection is used for the rapid screening THM's and other volatile organic compounds (VOC's) in water by direct on column injection of the water sample in to wide bore capillary columns, to which is attached an electron capture detector.

TL;DR: In this article, a wide bandwidth linear motor system with a coil assembly with a structure which suppresses secondary resonances was proposed, allowing the linear motor to be used in a wide-band servo control loop.
Abstract: A wide bandwidth linear motor system suitable for high performance applications such as driving the tuning plunger of a magnetron oscillator. The linear motor includes a coil assembly with a structure which suppresses secondary resonances, thereby permitting the linear motor to be used in a wide bandwidth servo control loop. The coil assembly includes a cylindrical coil support, a bushing coaxial with the coil support for attachment to the linear motor shaft, a plurality of radial ribs connecting the coil support to the bushing and a coil having multiple turns wound circumferentially around the coil support. The coil support is subdivided by axial gaps into at least two separate coil support elements, each connected by a radial rib to the bushing. Resonance of the coil support and the coil is suppressed by the separate coil support elements and the lossy connection therebetween.
