摘要:
A hydrogen generating system regulates its rate of hydrogen generation by monitoring one or more parameters of the hydrogen generation process and then providing relative movement between the fuel tank and the catalyst chamber so as to increase or decrease the rate of hydrogen generation.In the disclosed embodiments, the catalyst chamber is disposed in a tank containing the fuel. The relative movement provided moves the catalyst chamber toward the fuel solution so as to increase the rate of hydrogen generation and moves the catalyst chamber away from the fuel solution to decrease such generation. Advantageously, such self-regulation can be provided without an external power source and can be varied to meet the requirements of different commercial applications. The overall system can be readily fabricated using commercially available parts.

Fatty acid esters of which the fatty acid constituents are saturated and/or mono- or polyolefinically unsaturated fatty acids containing a total of 12 to 22 carbon atoms and of which the alcohol constituents are saturated and/or mono- or polyolefinically unsaturated monoalcohols containing a total of 1 to 22 carbon atoms, with the additional proviso that the fatty acid constituents of the esters contain an alicyclic group which may optionally be substituted by an aliphatic group, are suitable as solvents for printing inks.
摘要:
A self-dispersing curable epoxy composition is prepared upon contacting an epoxy resin with a polyoxyalkylenemonoamine having a molecular weight of from about 3,000 to about 15,000 in a ratio of about 0.001 to 0.060 reactive equivalents of polyoxyalkylenemonoamine to about 1.0 reactive equivalents of epoxy resin. The self-dispersing curable epoxy resin forms an aqueous dispersion upon mixing with water. When cured, the dispersion is useful as a coating composition.
摘要:
A circuit for generating a pulse signal in response to an input signal. The circuit provides a pulse width for the pulse signal. A first logic device receives the input signal and generates a first intermediate signal. A delay device is coupled to the first logic device and receives the first intermediate signal. The delay device generates a second intermediate signal in response to the first intermediate signal after a period of time. The second intermediate signal has the same state as the second intermediate signal. A second logic device is coupled to both the first logic device and the delay device. The second logic device generates the pulse signal in response to the first intermediate signal.

摘要:
The integrated circuit includes an input path circuit with an address path having an input buffer for providing address signals to a register. A separate clock path having an input buffer provides a clock signal for clocking the register. The input path circuit also includes one or more decode units each having a number of logic gate cells such as NAND gate cells or NOR gate cells. Circuitry is provided within the logic gates for reducing timing delay differences between propagation of multiple bit binary signals, such as address signals, through the logic gates. In an exemplary NAND gate described herein, reduction in timing delay differences is achieved by positioning an additional PMOS device along a current path between a power source and an output path otherwise including only a pair of parallel PMOS devices. The additional PMOS device acts as a choke on the current flow through the pair of parallel PMOS devices thereby reducing propagation delay differences which would otherwise occur as a result of either only one or both of the parallel PMOS devices operating to pull up the output path. Similar circuit modifications are provided within NOR gates or logic gates.
