  • Patent number: 9765538
    Abstract: Methods, systems and apparatuses for providing high electrical resistance for an upper control assembly (including control handles) of an aerial lift are provided through an isolation member that is integral to the upper control assembly and interposed between fluid lines in the control assembly and a set of fluid conduits that extend from the control assembly towards other portions of the aerial lift. The isolation member is a dielectric element that comprises a manifold that is made of material that is substantially electrically non-conductive, and that has a plurality of through-holes or hoses configured to allow hydraulic fluid to flow through the isolation member into and out of the fluid lines and conduits. These methods, systems and apparatuses are preferably used in upper control assemblies of aerial platforms that can carry one or more operators in order to prevent such operators from electrocution when controlling the lift.

  • Patent number: 9732739
    Abstract: Mixed concrete is pumped under pressure along a primary flow path to a typically lengthy supply line. In the event a clog, blockage or other supply line concern is detected, a branch conduit in communication with the primary flow path permits a portion or all of the pressurized flow to pass through a diverter valve and a recirculation conduit back into an open-to-atmosphere reservoir or hopper from which the concrete originally was pumped. The recirculation system of this invention permits supply line pressure to be safely regulated, diminished, relieved and jogged, all without there being any need to discharge or waste valuable mixed concrete, and without having to dangerously open one or more connections of a pressurized supply line.

  • Patent number: 8641153
    Abstract: A valve assembly, which houses a valve closing member that co-operates with an armature to connect or separate pressure medium channels in a valve housing, the member being directed towards a valve seat which is situated on a valve seat body fixed in the valve housing. The valve assembly includes a solenoid for actuating the armature which is pushed onto a non-magnetisable sleeve section of the valve housing and a magnetic core that is diametrically opposed to the armature in the valve housing. Various valve functions can be achieved by using identical valve components in a modular manner.

  • Patent number: 8596610
    Abstract: A universal control valve may use two different seat ring types including a threaded seat ring or a clamped seat ring. The valve includes a valve body, a cage mounting space enclosed by a bonnet and sized to receive two different valve cage types, and a seat ring mounting location including, an annular shoulder, a radiused projection, and a threaded portion. The threaded portion receives a threaded seat ring and the radiused projection forms a seal, while the shoulder supports a mounting flange of a clamped seat ring and forms a seal. Accordingly, the seat ring mounting location can receive a selected one of the two different seat ring types.

  • Patent number: 8539973
    Abstract: A normally open non-electric valve includes a flow path through an apertured valve seat . . . cavity isolated from the flow path is sealingly closed off adjacent the valve seat by a flexible diaphragm. The diaphragm is sufficiently flexible to be pushed and held away from the valve seat by fluid flowing in the flow path. When it is desired to close the valve, a pressure medium is introduced into the cavity so as to force the diaphragm against the valve seat and interrupt the fluid flow in the flow path. The normally open valve can inexpensively be converted from an inexpensive electric solenoid valve by removing the plunger, spring and coil from the electric valve, closing off the plunger cavity with a flexible diaphragm, and selectably introducing a pressure medium into the cavity when it is desired to close the valve.

  • Patent number: 8449289
    Abstract: Cooking appliance having an external control panel equipped with one or more regulating valves, where the rotary regulator organ is equipped with various peripheral openings for supplying a flow Q. For the supply of one or another type of gas, NG or LPG, either the control knob or a bezel disk in the external panel are interchangeable on the appliance, being chosen between two different available units, one and the other permitting two different angular position limits A2, A3 of the regulator organ or the supply of a constant flow Qmin through one or another opening with calibrated sections, respectively for NG or LP gas. An appendix in the control knob guided in a slide groove on the control panel of the appliance, or a tongue on the bezel disk stopping the rotation of the control knob, determines the travel limit A2 for the supply of Qmin of NG.

  • Patent number: 8381757
    Abstract: A valve device for a hydraulic circuit (10) divides the incoming volume flow into at least two pre-determined partial flows for supplying hydraulic consumers (V1, V2) of the circuit (10) and has at least one pressure balance (16) and at least one orifice. Since the orifice is embodied as a variable orifice (32) controllable by a proportional magnet (34), the opening area of the orifice varies. A flow regulator is then realized and can switch the regulated volume flow and/or proportionally adjust the regulated volume flow in a defined manner.
