Patent number: 6749091Abstract: A single dosage dispenser for delivering chemical reagent to a test sample includes a body having an inlet and opposing outlet. The inlet is threadably and communicably engaged with a container holding a chemical reagent. The outlet includes a plurality of stepped receptacles for communicably receiving respective sizes of test sample holders. A spring actuated plunger is slidably mounted within the dispenser body between the inlet and the outlet. The plunger includes a reagent accommodating compartment. The spring urges the plunger into a first state wherein the plunger is communicably connected to the inlet for receiving a single dosage of reagent from the container. The user presses the plunger to drive the plunger within the dispenser body so that the compartment is communicably connected to the outlet. As a result, the reagent in the compartment is dispensed through the outlet into the test sample holder.Type: GrantFiled: April 16, 2002Date of Patent: June 15, 2004Assignee: H. F. Scientific, Inc.Inventors: Rowan T. Connelly, Alvin L. Waltman

Patent number: 6749172Abstract: A rotary blowout preventer has a first and a second fluid circuit. Each of the fluid circuits are defined into and out of a stationary body and between the stationary body, a rotating body, and two seals. The first fluid circuit is physically independent from the second fluid circuit although they share a seal interface. A fluid is introduced into the first fluid circuit at a pressure responsive to the well bore pressure. A fluid is introduced into the second fluid circuit at a pressure responsive to and lower than the pressure of the fluid in the first circuit. Adjustable orifices are connected to the outlet of the first and second fluid circuits to control such pressures within the circuits. Such pressures affect the wear rates of the seals. The system can therefore control the wear rate of one seal relative to another seal. A thrust bearing is added to share the load placed upon the upper bearings. The thrust bearing is connected between the top end of a packer sleeve and the stationary body.Type: GrantFiled: April 25, 2003Date of Patent: June 15, 2004Assignee: Precision Drilling Technology Services Group, Inc.Inventor: Joseph Kinder
