Patent number: 6548307Abstract: This invention provides a RP-HPLC method, for the determination of logPoct values, which combines ease of operation and high accuracy, and which has been shown to work for a set of 36 molecules largely comprised of drugs. The general features of the method are: i) compound sparing (≦1 mL of a 30-50 &mgr;g/mL solution needed), ii) rapid determinations (20 minutes on average), iii) low sensitivity to impurities, iv) wide lipophilicity range (6 logPoct units), v) good accuracy, vi) excellent reproducibility. A linear free energy relationship (LFER) analysis, based on solvation parameters, shows that the method encodes the same information obtained from a shake-flask logPoct determination. The value generated via this method is referred to as ElogPoct.Type: GrantFiled: February 13, 2001Date of Patent: April 15, 2003Assignee: Pfizer Inc.Inventors: Franco Lombardo, Marina Y.

Patent number: 6439387Abstract: A method of packaging liquid detergent or fabric softener for single load use comprising thermoforming a container from a thermoplastic material such as polypropylene, polyethylene, polystyrene and the like, to a size sufficient to contain a 3-4 ounce amount of liquid detergent in a well thereof. The container comprises an open well with a peripheral lip an open end thereof. A printed foil strip, sized to cover the opening and at least a full circumferential portion of the container lip is heat sealed to the thermoplastic after the detergent is disposed therein. The foil and heat seal are of sufficient strength to retain the 3-4 ounces of liquid detergent even in an obverted position with jostling such as drug transport. Because of the heat seal, the container is not reclosable and storable and the full contents must be used once the container is opened, i.e., for a single use.Type: GrantFiled: July 20, 2000Date of Patent: August 27, 2002Assignee: Air Fresh Inc.Inventor: Daniel Bergman

Patent number: 6382264Abstract: A recyclable fuel distribution system comprising a hierarchy of operatively linked (with fuel supply and reaction product collection elements) fluid fuel transport vehicles, fluid fuel storage tanks, fuel supply reservoirs (optional depending on specific use), and fluid fuel usage devices operatively linked to the storage tanks or supply reservoirs, as applicable. The fuel, during use, undergoes a reversible chemical reaction, whereby collected reaction product is reversible to the original fuel. At least one and preferably all of the vehicles, storage tanks and reservoirs contain a storage volume with separated chambers, adapted to inversely change relative to fuel being supplied and reaction product being collected and stored. As a result, a single volume during transport, storage, and use, provides the dual function of fuel supply and collection of reversible reaction product, with concomitant nearly halving of transport, storage and use volumes and costs.Type: GrantFiled: June 21, 2000Date of Patent: May 7, 2002Assignee: Reveo, Inc.Inventors: Tsepin Tsai, Sadeg M.

Patent number: 6066924Abstract: A wax candle simulation device with random flicker electric circuitry, comprising at least two miniature light bulbs mechanically vertically closely arranged with the filaments therein arranged at an angle. The bulbs are contained within a flame shaped translucent housing and are connected to an electrical circuitry comprising two transistors, with one driving the other (inverter) with an external control and a switch between them set by resistor values. Additional resistors slow down light bulb shut down and the filaments are constantly pre-heated with a slow cool down, whereby the transition between the lighting of the light bulbs is very gradual. A single counter IC, creates the external driver circuitry with a portion of the IC providing a low stability oscillator and another portion operating as a counter with outputs connected to resistors. The other ends of the resistors are parallel and connected to the inverter.Type: GrantFiled: May 21, 1998Date of Patent: May 23, 2000Inventor: Gabor Lederer
