An actuator connected to receive high pressure gas from a pyrotechnic initiator incorporates a primary piston and a secondary piston mounted for limited movement along cylindrical bores in a housing; the pistons are held in a fixed inactive position and are restrained from movement within the housing by a tension screw connected to the primary piston and the housing. The tension screw incorporates a calibrated reduced diameter section that ruptures at a predetermined applied force to permit the pistons to move within the housing. Gaseous products resulting from initiation are trapped and maintained within the housing by an expandable bellows secured internally of the housing at one end of the bellows and secured at the opposite end of the bellows to the interior of the housing. A calibration/test port extends through the housing into the bore externally of the bellows to permit calibration and testing of the actuator without initiating the pyrotechnic device.

A process for the alkylation of a benzene-containing refinery stream such as reformate with light refinery olefins which is capable of achieving high benzene conversion levels operates in a fixed bed of an MWW zeolite catalyst, preferably MCM-22, in single pass mode in the liquid phase at a relatively low to moderate temperatures with pressure maintained at a value adequate to ensure subcritical operation. High levels of benzene conversion with conversions of at least 90% and higher, e.g. 92% or 95% or even higher are achievable. A high octane product is produced, comprising mono-, di- and tri-alkylbenzenes with lesser levels of the tetra-substituted products. By operating with staged olefin injection, the end point of the alkylation product can be maintained at a low value while, at the same time, achieving high levels of benzene and olefin conversion.

Disclosed are a recombinant acid-resistant yeast having lactic acid-producing ability and suppressed glycerol production and a method of preparing lactic acid using the same. More particularly, disclosed are a recombinant acid-resistant yeast into which a gene involved in lactic acid production is introduced and in which a gene involved in glycerol production is deleted or attenuated, and a method of preparing lactic acid using the same. When producing lactic acid using the recombinant acid-resistant yeast, the production of lactic acid is maintained while the production of glycerol is reduced, so crosslinking by glycerol can be suppressed in the oligomerization reaction for conversion to lactide, and thus the conversion yield of lactic acid to lactide can be increased.
