Patent number: 11306829Abstract: A low pressure, low operating force valve, for applications where automated valves are used, having reduced power requirements for an associated actuator. A low torque ball valve of a fixed ball valve configuration for low to medium pressure applications, such as for an electric motor actuated residential shutoff valve where pressures are typically below 100 psi, and commonly less than 60 psi, for example. The valve can be open or shut using a smaller electric motor than would be required for a conventional residential floating ball shutoff valve of a similar size. As such, the power requirements of the electric motor or other actuator are reduced allowing for the use of smaller motors, smaller power supplies and overall more efficient operation.Type: GrantFiled: October 16, 2020Date of Patent: April 19, 2022Assignee: LeakSmart Inc.Inventors: John C.

Patent number: 8091587Abstract: A system and method for installing and removing a flow restrictor assembly in a shower, while prevents tampering with the flow restriction system thus installed. Tampering is prevented by concealing the flow restrictor assembly behind a shower wall, attached directly to a water supply line. The system further prevents tampering by concealing the tool-hole necessary for its removal behind a flow restrictor disk, so that there are no visible means of removing the flow restrictor assembly. The flow restrictor assembly threads onto a showerhead arm and the flow restrictor assembly with the attached showerhead arm threads directly into the water line. When the showerhead arm is unthreaded, the flow restrictor assembly remains connected to the water line by an external screw thread. The flow restrictor must be removed to reveal the tool-hole which may only then be engaged by a tool for removal.Type: GrantFiled: January 28, 2010Date of Patent: January 10, 2012Inventor: David Schwartz

Patent number: 8091571Abstract: A valve box, a valve control device, an assembly thereof and a method are provided for accessing an underground valve and indicating presence and position of the underground valve. The valve box includes a support member having a tubular section; and a resilient tubular member telescopable slidably into the tubular section of the support member. An upper end of the resilient tubular member is extendable above the ground. Various elements are disclosed for stiffening the tubular member against deformation due to forces applied to it. The valve control device comprises a control rod having one end attachable to the underground valve and a control key including a key head, a key handle and a key stem. The key head has a cone-shaped cavity and a recess portion at the top of the cavity, the recess portion being dimensioned to engage a projection at the other end of the control rod.Type: GrantFiled: July 24, 2007Date of Patent: January 10, 2012Assignee: The Water-Box Development CorporationInventors: Edward Weisz, Jon Whiteside

Patent number: 8087639Abstract: An oxygen tank key includes an elongated substantially thin flat handle portion defining a first plane and having first and second ends that define the length thereof and first and second side edges that define the width. A socket, integrally formed with the handle portion between the two ends, has a thickness that is greater than the thickness of the handle portion. The socket includes an aperture that opens adjacent one of the side edges and has a depth extending substantially the width of the handle portion. The aperture has a substantially rectangular cross-section and is adapted to fit onto the rectangularly shaped end of an oxygen tank valve control stem. A slot passes through the handle and is elongated in the direction of the length of the handle. The slot includes champhered ends and is adapted to fit over the lever of a regulator for the oxygen tank to help release the regulator from the tank.Type: GrantFiled: December 31, 2007Date of Patent: January 3, 2012Inventor: Joshua Knapp

Patent number: 8061684Abstract: An anti-twist device retains an actuating motor (10), which is placed in a force-fitting and/or form-fitting manner onto the projecting driveshaft (22) of a pivotable shut-off flap (62) of a gas transport tube (34), in particular of an HVAC tube or flue gas tube for a building, in a longitudinally moveable manner. Arranged at an adjustable axial distance (a) from the driveshaft (22) is at least one clamp (36) which secures the actuating motor (10). The parallel limbs (46) of the preferably substantially U-shaped clamp (36) are of resilient design, wherein in each case one end-side, inwardly projecting latching lug (48) is formed for holding down the actuating motor (10).Type: GrantFiled: February 19, 2007Date of Patent: November 22, 2011Assignee: Belimo Holding AGInventors: Frank Lehnert, Urs Niederhauser
