Patent number: 6223746Abstract: A metered dose inhaler pump for delivering a metered dose of an active compound from an active compound inlet through a spray outlet without the need of a pressurized active compound container. Reciprocating action of an inlet valve, an outlet valve and a plunger alternately draw a metered dose of the active compound from an active compound container into an active compound chamber and pressurize the drawn metered dose of the active compound to eject the metered dose through the spray outlet. The plunger substantially fills and evacuates the metered dose chamber, leaving no void head space therein.Type: GrantFiled: February 12, 1998Date of Patent: May 1, 2001Assignee: IEP Pharmaceutical Devices Inc.Inventors: Warren R. Jewett, Robert C. Williams, III

Patent number: 5771920Abstract: A domestic water valve assembly protects against water leaks by closing a valve if a leak is detected. A leak is detected when a water flow rate falls below a predetermined low flow rate for a length of time longer than a predetermined time-out period or when the water flow rate exceeds a predetermined high flow rate. The predetermined high flow rate, low flow rate, and time-out period may be changed by an operator. When a leak is detected, a control system activates an electric motor to close a valve, the valve remaining closed until reset by the operator.Type: GrantFiled: August 4, 1997Date of Patent: June 30, 1998Assignee: FloLogic, Inc.Inventors: Warren R. Jewett, Perry A. Genova

Patent number: 5622163Abstract: The disclosure is of a device for indicating the number of fluid dispensations remaining in a container for holding and dispensing metered quantities of the fluid. The device is a hermetically-sealed unit which is assembled with the dispenser portion or component of the container and includes microprocessor means for maintaining an inventory of the doses or dispensations remaining of a predetermined number of dispensations. Indicator means signals when the predetermined number of dispensations reaches a level before empty.Type: GrantFiled: November 22, 1995Date of Patent: April 22, 1997Assignee: IEP Group, Inc.Inventors: Warren R.

Patent number: 5346672Abstract: A cover has been designed to make a sealed chamber over a desired specimen area to control reagent evaporation which is critical for amplifying DNA in slide specimens. The cover is positioned over the specimen and temporarily adhered to, or pushed against, the slide, forming a sealed chamber. Reagents are added through a channel in the cover with a standard pipette and the channel opening is closed to prevent evaporative loss of reagents. The chamber is also designed to relieve internal vapor pressure, which is creating upon heating, thereby facilitating diffusion in and out of cells rather than allowing high pressure to flatten cells against the slide surface. Increasing the height of the chamber upwards toward a neck in the cover allows air bubbles being formed during each cycle to leave the specimen area, while at the same time preventing water vapor loss or partitioning of water vapor condensate.Type: GrantFiled: March 2, 1993Date of Patent: September 13, 1994Assignee: Gene Tec CorporationInventors: Marilyn J. Stapleton, Villette S. Thorpe, Warren R. Jewett

Patent number: 4464563Abstract: An intravenous fluid warmer includes an electrically heated warmer module receiving a low volume (10 ml.) disposable cartridge through which the fluid being heated flows. The module is configured as two spaced concentric elongated metallic heating elements having attached electric heaters and defining therebetween an elongated plenum adapted to receive the disposable cartridge. The temperature of the heating elements is individually monitored by separate sensors and an electronic temperature control module maintains the inner heating element at a slightly higher temperature (36.degree. C.) than the temperature (34.degree. C.) at which the outer heating element is maintained. The inner heating element is free floating through a limited range to accommodate manufacturing differences is the disposable cartridge. The cartridge, made of polystyrene or polycarbonate plastic, nests in the plenum in contact with the heating elements.Type: GrantFiled: August 28, 1981Date of Patent: August 7, 1984Inventor: Warren R.
