International Classification:

F17C 11/00
B01D 19/00

US Classification:

95241, 222 3

Abstract:

This invention relates to an improvement in a low-pressure storage and delivery system for gases having Lewis basicity, particularly hazardous specialty gases such as phosphine and arsine, which are utilized in the electronics industry. The improvement resides in storing the gases in a liquid incorporating a reactive compound having Lewis acidity capable of effecting a reversible reaction between a gas having Lewis basicity. The reactive compound comprises a reactive species that is dissolved, suspended, dispersed, or otherwise mixed with a nonvolatile liquid.

International Classification:

B01D 53047

US Classification:

95 98

Abstract:

A pressure swing adsorption process for absorbing CO. sub. 2 from a gaseous mixture containing CO. sub. 2 comprising introducing the gaseous mixture at a first pressure into a reactor containing a modified alumina adsorbent maintained at a temperature ranging from 100. degree. C. and 500. degree. C. to adsorb CO. sub. 2 to provide a CO. sub. 2 laden alumina adsorbent and a CO. sub. 2 depleted gaseous mixture and contacting the CO. sub. 2 laden adsorbent with a weakly adsorbing purge fluid at a second pressure which is lower than the first pressure to desorb CO. sub. 2 from the CO. sub. 2 laden alumina adsorbent. The modified alumina adsorbent which is formed by depositing a solution having a pH of 3. 0 or more onto alumina and heating the alumina to a temperature ranging from 100. degree. C. and 600. degree. C. , is not degraded by high concentrations of water under process operating conditions.

US Classification:

206531

Abstract:

A dispenser for solid dosage form pharmaceutical preparations for self-administration on a daily basis related to the menstrual cycle is made up of a blister pack in a carrying case. The case has a septagonal post and the blister pack a cooperating septagonal opening. The dose form to be taken on the first day is indicated and is aligned with the day taken. The remaining dose forms are taken sequentially. Once inserted on the starting day, the blister pack is not moved. A triphasic, 21-day regimen for oral contraceptives is described which may be followed by seven days of iron tablets.
