Device removes hydrogen gas from enclosed spaces

Hydrogen-oxidant galvanic cell removes small amounts of hydrogen gas continually released from equipment, such as vented silver-zinc batteries, in enclosed compartments where air venting is not feasible. These cells are used in satellite compartments

Hermetically sealed cells protected from internal gas pressure

Manufacturing process prevents damage to hermetically sealed nickel-cadmium secondary cells by buildup of gas pressure during overcharging and reversed charging conditions. The cells are manufactured with less charge capacity in the positive electrode than in the negative electrode, and two additional electrodes are added

Dielectric prisms would improve performance of quasi-optical microwave components

Properties of the Brewster angle and internal reflection in a dielectric prism are proposed as the basis of a new type of element for use in oversize waveguide in quasi-optical microwave components. Waveguide loss is reduced and precision broadband attenuators, phase shifters, and directional couplers can be constructed on the basis of the properties

Storage and feeding of coal

Reliable feeding of coal from storage bins to process requires the knowledge of the behavior of coal during flow. The study of the flow of bulk solids was undertaken in the 1950's and led to the development of flow ability testing equipment and of the Mass Flow concept of design for reliable flow. The theory has since been expanded to two-phase, solids-gas system, and has found world wide application in the design of storage and feeding systems

Conflicts of interest in self-regulation : can demutualized exchanges successfully manage them?

The author examines the implications of demutualization of financial exchanges for their roles as self-regulatory organizations. Many regulators and exchanges believe that conflicts of interest increase when exchanges convert to for-profit businesses. Demutualization also changes the nature of an exchange's regulatory role as broker-dealers'ownership interests are reduced. These factors are leading to reduced regulatory roles for exchanges in many jurisdictions. The resulting changes have significant implications for regulation of financial markets, especially as exchanges are the only self-regulating organizations (SROs) in most countries. Major changes in the role of exchanges require a rethinking of the allocation of regulatory functions and the role of self-regulation, as well as stronger mechanisms to mitigate conflicts of interest. Carson looks at the views of both exchanges and regulators on these issues in Asian, European, and North American jurisdictions where major exchanges have converted to for-profit businesses. He finds that views on the conflicts of interest faced by demutualized exchanges vary widely. In addition, the tools and processes used by exchanges and regulators to manage conflicts also differ significantly across jurisdictions. The author concludes that new and greater conflicts result from demutualization and canvasses the regulatory responses in the jurisdictions examined.Economic Theory&Research,Payment Systems&Infrastructure,Non Bank Financial Institutions,International Terrorism&Counterterrorism,Environmental Economics&Policies,International Terrorism&Counterterrorism,Non Bank Financial Institutions,Environmental Economics&Policies,Insurance&Risk Mitigation,Economic Theory&Research
