Abstract: ABSTRACT         A double diaphragm, two stage vacuum break device in which the vacuum break plunger operates in a first stage in re-sponse to movement of one diaphragm assembly and in a second stage in response to movement of a pair of diaphragm assemblies.     Metering valves are employed to cause delay of movement of the vacuum break devices in each of its ranges and delay can be eliminated from a selected one or both of the stages of move-ment by omitting a valve member.  The stages of movement are under the control of separate sources of vacuum, a selected one of which may be under control of a temperature responsive valve.  The range of movement of the plunger in its two stages of operation may be adjusted by mechanical means or a member responsive to temperature.

Abstract: ABSTRACT A process for the substantial removal of carbon dioxide from a normally gaseous mixture containing the same, which comprises:    (a) in an absorption step, contacting said normally gaseous mixture with an aqueous absorbing solution containing from about 5 to about 65 weight percent of at least one mildly sterically hindered water-soluble primary monoamine defined as having a secondary carbon atom attached to the amino group to absorb the carbon dioxide in said aqueous absorbing solution, wherein the absorption step is conducted at temperatures in the range from about 20° to about 100°C and the partial pressure of the carbon dioxide in the feed gas is in the range from about 1 to about 1000 psia; and (b) in a regeneration step, desorbing absorbed carbon dioxide from said absorbing solution at temperatures in the range from about 50° to about 170°C and at pressures ranging from about 1 to about 50 psia until at least more carbon dioxide is desorbed from the absorbing solution than would be desorbed from an absorbing solution containing the same amount of mono-ethanolamine under the same conditions of regeneration.   Aqueous solutions containing water-soluble primary monoamines having a secondary carbon atom attached to the amino group provide the same high cleanup and fast absorption rates as aqueous solutions containing monoethanolamine, with the advantages of slightly higher capacity and much easier regeneration than the monoethanolamine solutions.

These resins are fabricated into cups, tubs, bowls, trays and similar articles by deep draw thermoforming or high-speed injection molding.  For such service, it is desired that the im-pact polystyrene resins have melt toughness or resistance to thinning in cross section while being formed in the molten state as well as satisfactory general molding and physical property characteristics.  Also, it is advantageous to have impact poly-styrene resins that with minor changes in the polymerization recipe for the resin can be used for injection molding and ex-trusion or extrusion alone.
