Patent number: 3961642Abstract: A fire hydrant is designed to break away at the point of the coupling between the upper and lower standpipes when hit by a moving vehicle or the like, to reduce the chance for damage to the hydrant, the vehicle and possibly to the occupants of the vehicle. A valve push rod extends from a valve operating nut at the top of the hydrant down to operable connection with a hydrant valve so that the valve can be opened when water is to be delivered through the hydrant. To provide a breakaway connection for the push rod, a semi-cylindrical frangible coupling sleeve connects an upper valve rod section to a lower valve rod section in about the same horizontal plane as the upper and lower standpipes are coupled to each other. Then when the upper standpipe is broken away from the lower standpipe, the frangible coupling sleeve will also break, allowing separation of the upper valve rod section from the lower valve rod section without substantial danger of damage to the hydrant.Type: GrantFiled: March 10, 1975Date of Patent: June 8, 1976Assignee: Waterous CompanyInventors: David F.

Patent number: 3960149Abstract: A flow control device for accurately regulating the flow of fluid through flexible tubing. A pivotal platen is employed in conjunction with a roller which upon rotation along an intersecting axis with a length of tubing will effect a squeezing or compressive action on the tubing but with the compressive force being applied over a wide area of the tubing so as to not effect a distortion of the tubing after the compressive force is discontinued. The flow control unit can be utilized as a clamp in that it can completely disrupt the flow of fluid through the tubing yet it is highy adapted to being used as a flow control device in conjunction with a parenteral administration set.Type: GrantFiled: November 13, 1974Date of Patent: June 1, 1976Assignee: Abbott LaboratoriesInventor: Albert Frank Bujan

Patent number: 3958592Abstract: Pressurized fluid is controlled by a reverse valve gate on a valve stem that extends through annular packing in a bore of a bonnet to a piston in an outer control chamber. Control fluid pressure moves the piston inward to open the valve against line pressure on the valve and/or spring pressure on the valve. In the absence of both line pressure and control pressure, the valve is closed by spring pressure. The control chamber construction permits quick replacement of control chamber seals. In the event of a fire, the control chamber seals disintegrate to release the control pressure and thus cause line pressure and/or spring pressure to close the valve. The valve stem packing may be conveniently expelled hydraulically for replacement. Various different control assemblies may be mounted interchangeably on the valve bonnet without disturbing the structure of the valve. An auxiliary control may be quickly mounted on the outer end of the control chamber to convert the shut-off valve to manual operation.Type: GrantFiled: February 6, 1974Date of Patent: May 25, 1976Assignee: Willis Oil Tool Co.Inventors: Richard E. Wells, Victor E. Derval, John D. Muchow
