Patent number: RE34787Abstract: A bidirectional gasket providing a water-tight seal between an opening in a manhole assembly and a pipe extending into said opening, comprises a T-shaped anchoring portion for embodiment in a manhole opening. A substantially A-shaped pipe engagement portion is joined to the anchoring portion by a slender connecting web facilitating bending of the gasket. The A-shaped portion has "legs" and recesses which form water pockets preventing water from entering. The durometer of the gasket material enhances the water-tight seal of the legs with increasing water pressure. The pipe engaging portion accommodates a greater outside pipe diameter compared with conventional connectors due to reduced volume, by providing voids within the connector together and a lower durometer of gasket material. The gasket has enhanced ability to accommodate diameter deflection or ovation in rigid and flexible pipe materials.Type: GrantFiled: July 21, 1993Date of Patent: November 15, 1994Assignee: Poly-Tec Products, Inc.Inventors: James A.

Patent number: 5363519Abstract: Disclosed herein is a drain valve for a bathtub or other gravity drained container. When energized with an electrical pulse, a solenoid mounted directly below the drain elbow drives the poppet upward, which unseals the outlet drain. A permanent magnet latches the solenoid armature in place in the up position. The valve is closed by energizing the solenoid with a pulse of opposite polarity which pulls the armature downward and out of the influence of the permanent magnet. A piston in a sleeve over-nested by a movable shroud provides leakage protection and allows manual opening and closing.Type: GrantFiled: December 23, 1992Date of Patent: November 15, 1994Assignee: Kohler Co.Inventor: Thomas J.

Patent number: 5363520Abstract: A free-standing, self-supporting bed has a movable platform supported by a stationary frame. The platform may be elevated vertically to a stored position higher than head height when the bed is not in use. Counterweights allow the platform to be elevated and lowered with a minimum of effort. In the stored position the platform is suspended from the frame by redundant lines passing over pulleys. In the sleeping position the counterweights are suspended from the frame and the platform rests on the frame and may be secured thereto by latching devices operable from one side of the bed. The lines and pulleys are arranged so that the counterweights have a 2:1 mechanical advantage with respect to the platform and so that, during raising or lowering of the platform, forces keeping the ends of the platform horizontal are automatically exerted thereon.Type: GrantFiled: March 16, 1992Date of Patent: November 15, 1994Inventor: Robert C.
