Patent number: 9777852Abstract: A non-return valve fitted on a tubular element for use for the reinforcement and consolidation of soil, for example, in an excavation. The non-return valve includes a portion of elastomer material which has a nick and is connected to a structural body tightened onto the tubular element. The structural body can be connected rigidly to the portion of elastomer material or may be at least partially incorporated therein. The body has a central portion with a window within which the nick is arranged, and the edges of the nick open out and function as a non-return valve under the action of a fluid under pressure injected into the interior of the tubular element and emerging from radial holes in the vicinity of the nick.Type: GrantFiled: December 28, 2015Date of Patent: October 3, 2017Assignee: ELAS GEOTECNICA S.R.L.Inventor: Cristiano Bonomi

Patent number: 9777469Abstract: The present invention provides a control valve for a water channel, which comprises of, from top to bottom, a control shaft bolt, a sliding valve disc, a fixing valve disc and a valve base. A valve shell combining with the valve base covers around a lower portion of the control shaft bolt, the sliding valve disc and the fixing valve disc to prevent mentioned components from falling out. The amount and the open/close operation of the two different kinds of water sources can be operated and controlled by a single control valve of the water channel to simplify the complexity in structure. Also it is convenient for a user to control the amount and the open/close operation of two different water sources by a single control valve.Type: GrantFiled: September 27, 2015Date of Patent: October 3, 2017Assignee: GEANN INDUSTRIAL CO.

Patent number: 9759341Abstract: A freeze tolerant ball valve for controlling the direction of expansion of freezing water within the ball valve is disclosed. The valve includes valve body inlet and the valve body outlet, and a spherical-shaped gate that has an axial fluid passage that extends through the spherical-shaped gate. The spherical-shaped gate can be rotated to block fluid communication between the valve body inlet and the valve body outlet. The valve body also has a first sidewall that is of a first sidewall thickness, and a sidewall having a boss that supports a concave cap that has a bottom wall that is of a bottom wall thickness, the bottom wall thickness being substantially thinner than the sidewall thickness. The cooperation of the passage through the spherical-shaped gate, the first sidewall with its first sidewall thickness positioned opposite to the bottom wall of the concave cap results in a valve that directs the effects of freezing on to the concave cap, which would fail first in the event of freezing.Type: GrantFiled: April 7, 2016Date of Patent: September 12, 2017Inventor: Ronald Lehman

Patent number: 9752731Abstract: Systems and related methods for conserving various resources, such as, but not limited to, water, laundry chemicals, natural gas, electricity, linen, labor, and wear on equipment (e.g., a solenoid valve of a commercial washing machine drain line). The inventor has spent the past 14 years in the industrial chemical field, allowing him to access and service commercial washing machines, and has discovered that drain issues relative to such commercial washing machines result in enormous losses to such institutions that process a large volume of laundry. Such typical institutions include, but are not limited to, hotels, hospitals, prisons, universities, colleges, laundries, and nursing homes. By replacing a portion of the opaque drain pipe section between the valve and the floor drain, operators and technicians can quickly determine if a leak is occurring, and take corrective action. An access port may also be provided to test characteristics of discharged wash water.Type: GrantFiled: July 30, 2015Date of Patent: September 5, 2017Inventor: Kevin C. Goodsell

Patent number: 9752696Abstract: Embodiments of the present invention generally include a pressure relief system and methods of use, in which an apparatus includes an upper chamber fluidly connected to a pressurized fluid source, a lower chamber having an inlet and an outlet, a vertically moveable plate intermediate the chambers and disposed within a plate support, and connected to the plate by a vertical shaft, a vertically actuating lower chamber inlet valve including an inlet seal. Pressure relief is accomplished by controlling fluid pressure in the upper chamber such that varying downward force on the plate and therefore, via the shaft, the inlet seal, allows for selective opening/closing of the inlet valve as a function of upper chamber fluid pressure relative to the pressure exerted from a fluid source for which pressure relief is desired, beneath the inlet seal, whereby over-pressured fluid entering the lower chamber via the inlet is vented out the outlet.Type: GrantFiled: October 13, 2015Date of Patent: September 5, 2017Inventor: Strom W. Smith
