Abstract: A buccal delivery system capable of being blended in a normal dry powder process and compressed using a standard tabletting machine, said buccal delivery system comprising a matrix of: (a) an effective amount of one or more active ingredients; (b) an amount of one or more polyethylene glycols or derivatives thereof having a molecular weight between 1000 to 8000 sufficient to provide the required hardness and time for dissolution of the matrix; (c) 0.05-2% by weight of the total matrix of one or more suspending agents; (d) 0.05-2% by weight of the total matrix of one or more flowing agents; and (e) 0.05-2% by weight of the total matrix of one or more sweeteners.

Abstract: A water purification system for saltwater or otherwise polluted water. The system employs one or a plurality of tower like structures formed of a plurality of engaged modular individual boilers. Increased energy efficiency is obtained using rising heat from lower situated boilers in a communication with above situated modular boilers, through a channel surrounding the exterior of the stacked modular boilers. Incoming water is thereby subjected to a super heating process to render it potable and collected on exiting the top of the stacked modular boilers.

Abstract: A distillation device for treating liquid to be purified comprising: a) a boiler having an upper chamber (1B) and a lower chamber (1A); b) a liquid delivery system (1) for delivering the liquid to the lower chamber (1A); c) a heater (14) to heat the lower chamber (1A) to a predetermined temperature at which the liquid will be vaporized upon entering and/or contacting a surface of the lower chamber (1A); d) a vapor collector (9, 11) located in the upper chamber (1B) to receive and collect the vapor emanating from the lower chamber (1A); and e) a condenser (1C) in communication with the vapor collector (9, 11) to receive and condense that vapor into purified liquid.

Abstract: Access control system in which a magnetically coded key or card is inserted into a reader which reads the recorded code. The key is coded by small permanent magnets embedded in non-magnetic body of the key at positions on a 4 .times. 4 regular grid of possible positions. The reader includes 16 Hall Effect devices which are disposed adjacent keyway in the reader so as to register with the 16 possible magnet positions on the key when the key is inserted. Signals are generated in those Hall effect devices which register with magnets in the key and these signals are amplified to produce reader output.
