Abstract: The present invention is a new electronic memory-assist device which can be used to remind an individual when it is time to take a prescribed medicine. The invention uses complementary metal-oxide semiconductor technology in conjunction with surface-mounted device technology to provide a programmable portable unit. The device has three parts: a body-carried reminder, a local interactive compliance processor and a supervisory unit. The reminder has a portable power supply, microprocessors, software, memory, an alarm, an input key and communication linkage to the compliance processor. The compliance processor has a central processing unit, a pill case, a modem and, possibly, a recharger for the portable power supply. The supervisory unit is connected to the central processing unit remotely by modems. The device operates by providing data to the user through an alarm that it is time to take prescribed medication. The alarm is visual, auditory, tactile or any combination of the three.

Abstract: A process of making a deicing or dust control agent with reduced corrosivity comprises mixing spent sulfite liquor and chloride salt of an alkali metal or alkaline earth metal proportionally so that the ratio of lignosulfonate solids of the spent sulfite liquor to metal chloride salt is from about 1:25 to about 15:1 and the pH of the mixture is from about 4.5 to about 8.5. The sulfite liquor: chloride salt product can be spread onto road surfaces in dried form, sprayed on as single or multiple solutions, and/or mixed with a non-slipping agent or the like.

Abstract: A process is described for clarification of an aqueous liquid by imparting magnetic characteristics to flocculated particles by addition of a ferromagnetic organic composition to the liquid to associate the ferromagnetic composition with the flocculated particles.

Abstract: A process for the preparation of aryl sulfonate-aldehyde condensate compositions having magnetic properties which may be water-soluble and compositions thereof are described.

Abstract: A process for recovery of dissolved mercury salts from aqueous solution is described which involves precipitating the mercury as mercury sulfide and contacting the solution with zinc sulfide particles.

Abstract: A process for the separation of mannitol from galactitol is disclosed which comprises selectively crystallizing mannitol from an alkanol-water solution of the mixture to which a small amount of a soluble salt of an iron, nickel, or cobalt has been added.
