International Classification:

A61M 5/315

US Classification:

604500, 604218, 604228

Abstract:

An apparatus and associated method are provided for controlling the plunging action of a syringe. A plunger control device includes an attachment member adapted to fixedly engage a syringe barrel. A translating member is slideably engaged with the attachment member. The translating member includes an elongate guide member slideably engaged with the attachment member such that the translating member is slideable with respect thereto between a proximal end and a distal end of the elongate guide member. The translating member further includes a plunger attachment portion disposed about the distal end of the elongate guide member and adapted to receive a portion of a syringe plunger for coupling thereto. The translating member further includes an engagement member extending from the proximal end of the elongate guide member so as to be spaced-apart from the syringe barrel when the attachment member is engaged with the syringe barrel.

International Classification:

C07C 110

US Classification:

518700

Abstract:

A process is described using novel thallium-promoted iron catalysts in CO hydrogenation with steam. Mixtures of CO and steam are converted to liquid C. sub. 6 -C. sub. 13 hydrocarbons containing substantial amounts of C. sub. 6 -C. sub. 13 aromatics.

International Classification:

B01J 2108
B01J 3100
B01J 2722
B01J 2724

US Classification:

502258

Abstract:

Disclosed is a method for preparing dual colloid catalyst compositions which are suitable for use in such processes as ammonia synthesis, carbon monoxide hydrogenation, hydrogenation and denitrogenation. The method comprises forming a gel, or suspension, by admixing: (i) one or more transition metal cyano-containing anionic-complex solutions wherein at least one solution contains a reducible transition metal, and wherein one or more of these solutions optionally contains a nonreducible metal, with (ii) one or more solutions containing polyvalent metal cations. The resulting gel, or suspension is heated to a temperature of about 90. degree. C. to about 150. degree. C. for an effective amount of time to allow hydrolysis and polymerization to occur. The resulting solid is then filtered and ion exchanged with ions of one or more metals selected from those exchangeable metals from groups IA, IIA, IIIB, IVB, VIB, VIIB, and VIII of the Periodic Table of the Elements. The resulting ion-exchanged material is then dried.
