Abstract: Nucleic acid hybridization probes for human papillomavirus types and particularly human papillomavirus type 56; and methods for employing the same.

Abstract: A valve for dividing a fluid flow at an inlet port subject to variable flow volume into two fluid flows at first and second outlet ports having a substantially constant ratio of flow volumes, including first and second flow passages from the inlet port to the first and second outlet ports. Each flow passage includes a variable orifice the openings of which are varied by fluid pressures proportional to the fluid pressure acting on opposite ends of a spool valve. A normally closed valve is provided for permitting an increase in fluid flow through the first outlet port when the inlet fluid flow exceeds a predetermined pressure.

Abstract: A faucet of the type for controlling volume flow of fluids therethrough and for further controlling and varying the temperature of said fluids as determined by the operator of the faucet, for the purpose of effecting mixing of cold and hot water or cold and hot fluids whereby the resultant temperature may be selected from the temperature of the cold fluid supply to the temperature of the hot fluid supply or therebetween.

Abstract: A valve, such as a butterfly valve, having an adjustable valve seat. The valve includes a valve body having an interior passage and a valve member journalled in the body for movement between positions opening and closing the passage. The body further includes an inwardly opening groove for receiving a valve seat formed of a flexible material. Also received within the groove is an arcuate structure, the circumference of which can be selectively adjusted. As the circumference is increased, the arcuate structure bears against the valve seat to compress the same and distort a portion thereof into the passage to provide good sealing contact with the valve member.
