Abstract: An improved feeding mechanism is provided for apparatus used for evacuating and compacting filled aerosol cans. The feeding mechanism is made up of a support plate adapted to be fitted into an inclined feed chute of a compaction and evacuation apparatus. Connected to the support plate is a rocker stop which by reciprocating between first and second positions serves to feed one can at a time into the crushing mechanism. By use of a toggle mechanism connected to both the rocker stop and a chamber door and operated by a pneumatic cylinder, the chamber in which the compaction and evacuation of the containers takes place is separated from the feed mechanism. The feeding mechanism and rocker stop are retained by quick-disconnect devices so that an entire feeding mechanism may be quickly substituted to adapt to feeding cans of different sizes.
Abstract: Herein is disclosed compounds of the formula ##STR1## in which R.sup.1,R.sup.2,R.sup.3,R.sup.4 and R.sup.5 each is hydrogen or lower alkyl, therapeutically acceptable acid addition salts thereof, processes for their preparation, methods of using the compounds and pharmaceutical compositions. The compounds exhibit dopamine-receptor stimulating activity in a mammal and are useful for treating hyperprolactinemia, galactorrhea, amenorrhea, impotence, Parkinsonism, diabetes, acromegaly, hypertension and other central nervous system disorders.
Abstract: A process and intermediates for preparing 6-(lower alkoxy)-5-(trifluoromethyl)-1-naphthalenecarboxylic acid derivatives are disclosed. The derivatives are useful for preparing aldose reductase inhibitors. With reference to the process, 1,1,1-trifluoro-5-(2-methylphenyl)-2,3-pentadione 3-oxime is cyclized to give a key intermediate 3,4-dihydro-1-hydroxy-5-methyl-1-(trifluoromethyl)-2(1H)-naphthalenone oxime; and 3,4-dihydro-1-hydroxy-5-methyl-1-(trifluoromethyl)-2(1H)-naphthalenone is aromatized to 5-methyl-1-(trifluoromethyl)-2-naphthalenol with a dehydrating agent.

Abstract: Spherical frozen particles, which may be subsequently freeze dried are prepared by introducing a liquid medium in the form of droplets beneath the surface of a cooling liquid. The temperature and density of the cooling liquid is chosen so that liquid droplets freeze as they float towards the surface of the cooling liquid. Preferably a column of cooling liquid is employed and the liquid medium is introduced through an inlet near the base of the column.
