  • Patent number: 10507258
    Abstract: A new diffuser for essential oils and the like is rendered more compact by integrating the entire diffuser into a form of cap threaded to fit a bottle operating as a reservoir. The motor and pump system are integrated into a package sleeved inside a housing that then receives in a silo beside the pump and motor the entire reservoir and diffuser system. Simplified control algorithms provide a limited set of buttons that are more intuitive by which a user need only define total time of operation, some level of intensity of scent, and an indication of the comparative size of the space to be conditioned by the diffused scent.

  • Patent number: 10493610
    Abstract: A hydraulic hammering device that uses a scheme in which a front chamber is switched into communication with a low-pressure circuit when a piston advances, wherein occurrences of “galling” to the piston at a sliding contact portion with a front-chamber liner is reduced. The front chamber has the front-chamber liner fitted to an inner surface of a cylinder. A hydraulic chamber space communicating with the front chamber and filled with hydraulic oil is formed as a cushion chamber on the inner peripheral surface of a rear portion of the front-chamber liner. The cushion chamber has a second drain circuit (from first end face grooves to slits to second end face grooves), which is provided separately from a drain circuit that guides the hydraulic fluid passing through a liner bearing of the front-chamber liner to the low-pressure circuit.

  • Patent number: 10485190
    Abstract: A center pivot irrigation system is described that includes a controller that makes use of a particular flow rate of input water to deliver differing or variable depths of irrigation to two or more user-defined areas under a pivot irrigator. The controller operates to pulse control valves for the nozzles/sprinkler heads on and off as the sprinkler arm rotates. The valve pattern along the span of the sprinkler arm is chosen during each operating cycle such that the total water flow through all the open valves matches the flow rate of the input or supply water to the pivot irrigator. To ensure the variable application depth, the speed may be changed during valve duty cycles. A farmer may define an irrigation plan that defines the variable rate irrigation (VRI) zones and also defines exclusion or no spray zones in which no irrigation should occur.

  • Patent number: 10478921
    Abstract: A method for generating, in layers, an application structure made of high heat resistant super alloys on a substrate is provided. A powdery construction material is melted by an energy beam at a working point, wherein the working point is guided across the substrate along a primary movement direction and thus swings transversely to the primary movement direction. The working point thereby swings from a first edge of a respective layer of the application structure to a second edge of the layer. In this way, a time interval passes between departure from a respective edge and a return to the respective edge directly following the departure, such that a melt bath on the respective edge solidifies into a paste-like zone during the time interval.

  • Patent number: 10478917
    Abstract: A welding system comprises a two manipulators and a controller. A first manipulator has a joint detection device and a first welding device, usually of the laser type while the second manipulator has a second welding device, usually of the arc weld type. The joint detection device is operative to read welding joint characteristics along a welding joint. The controller determines a corrected trajectory based on a predetermined welding trajectory and on the welding joint characteristics read by the joint detection device. This corrected trajectory is transmitted with a first time delay to the first manipulator and with a second time delay to the second manipulator. The second time delay is a function of a distance between the joint detection device and the second welding device. A corresponding method for welding components along a welding joint is also disclosed.
