摘要:
Ceramic compositions which exhibit the phenomenon of superconductivity are disclosed. Methods of making and using the compositions are included. The compositions comprise 1-2-3 ceramic compositions (e.g., Y, Ba, Cu/Ag) with the fourth constituent comprising sulfur, selenium or tellurium. Unexpectedly high temperature (e.g., non-cryogenic) and essentially atmospheric pressure superconductor characteristics are shown.

摘要:
An improved method, and resulting product, for creping a web of papermaking fibers by adhering the web to a creping dryer and with a creping blade removing the web from the creping dryer which provides increased absorbency with less reduction in strength. The improvement comprises reducing the cohesive forces between the fibers to a greater extent than reducing the adhesive forces between the web and the creping dryer accomplished by applying a fluid at least primarily comprising water overall to the side of the web away from the creping dryer in sufficient quantity and at a position to accomplish the improved results. The method is particularly useful in the practice of wet creping wherein the web is creped from the creping dryer at a dryness of from 45% to 60%.
摘要:
A device, method, and system for developing, managing, acquiring and playing electronic board games. Game developers may illustratively access one or more electronic game board, game piece templates and/or other game development application software from a game server to design and develop electronic board games. Such electronic board games may then be acquired by game players in the form of full, limited and/or modifiable versions. A game service module of the game server makes a number of electronic board game related services available to game players for managing, playing and acquiring electronic board game collections and/or for enhancing or facilitating electronic board game playing.
摘要:
The invention provides an electric fence charger of the type that periodically provides high voltage electrical shock pulses through an electric fence wire. The fence charger has a low voltage power source that powers the fence charger and supplies a charging current. An energy converter converts the low voltage and charging current of the power source to high voltage for storage in a high voltage storage means. A timer emits pulse discharge control signals on a periodic basis and these control signals are used to control discharge of the stored high voltage for delivering shocking pulses into the fence wire. A regulator adjusts operation of the energy converter to provide a minimum high voltage energy level as long as the power source voltage exceeds an established power source voltage reference. In another embodiment of the invention, a fence charger employs a DC-DC flyback converter for charging a high voltage storage means to a discharge voltage level which provides a minimum shock energy pulse. This embodiment includes means for operating the flyback converter at a constant frequency and means responsive to battery voltage for changing the flyback converter duty cycle to regulate the discharge voltage level.
