An automatic control system for a construction machine includes the construction machine provided with a ground leveling implement, a target, and a laser sensor; a survey unit that has a coordinate position measuring element and projects a beam of tracking light indicating a finished-plane height toward the target; a storage unit for storing finished-plane height data in correspondence with a horizontal coordinate position in the coordinate position; a computation unit for computing the finished...

A powder inhaler comprises a medicament container, a rotatable metering disc extending into the interior of the medicament container and an air channel through which air is drawn via a mouthpiece. The metering disc has one or more peripherally located dosing grooves extending axially through the metering disc. The dosing grooves are filled with a metered dose of the medicament while being inside the medicament container and are transferred to the air channel wherein the stream of inhaled air dis...

The invention relates to a method for producing copper in a hydrometallurgical process from copper-bearing raw materials, such as sulfidic concentrates. The concentrate is leached in a leaching stage of several steps into a chloride-based solution. The copper-bearing solution obtained from this leaching is subjected to reduction and solution purification, whereafter the copper contained in the solution is precipitated as copper oxidule by means of alkali hydroxide. The alkali chloride solution f...

An image recording apparatus has a photoconductive drum and a roller, e.g., developing roller, in pressure contact with the photoconductive drum. The photoconductive drum rotates on its rotational axis and has drum gears rotatable about the rotational axis. The drum gears are at opposite ends of the rotational axis. The roller is in pressure contact with the photoconductive drum and rotates on its rotational axis substantially parallel with the rotational axis of the photoconductive drum. The ro...

New ruthenium dimeric complexes with high antimetastatic and antitumour activity and remarkable chemical stability are described.

An apparatus and method for externally managing data within an asynchronous pipeline. The asynchronous pipeline over which control is sought includes a data path and a control path. In accordance with the method of the present invention, a data tag value is assigned to the data prior to its entry into the asynchronous pipeline. The data tag value is sent into the control path at the same time the data is sent into its data path such that the data tag value passes through the asynchronous pipelin...

A gravity-operated anti-surge valve for a turbine pump consists of a poppet adapted to be moveable under fluid pressure between a closed position and a valve seat for the poppet. The weight of the poppet biases the poppet in the closed position against the valve seat in the absence of fluid pressure. Fluid pressure developed by the pump forces the poppet open. As fluid pressure decreases when the pump is shut off, the weight of the poppet allows the poppet to gradually close against continuing f...

A system for moving watercraft for storage inside a dry stack watercraft storage facility. The system includes a frame assembly, a cradle assembly and a rack assembly which closely interact with each other to precisely and securely position and protect watercraft stored inside the facility. The cradle assembly lifts a watercraft from the watercraft's center of gravity to position in the rack assembly. The rack assembly supports the watercraft through a pair of cantilever beams, and further inclu...

A bunting bag, particularly well suited for use with children and child carriers, has a top portion detachably coupled to a bottom portion so that the top portion may be completely removed from the bottom portion. The bottom portion is configured or shaped to nest or mate in the child carrier without folds or substantial overhangs. The bottom portion has a head, back, seat, leg, left and right portions and surface area. The top portion has a head, body, and leg portion and preferably covers the ...

A method to provide a highly intelligent, automated diagnostic system that identifies the need to replace specific parts to minimize machine downtime rather than require extensive service troubleshooting. In particular, a systematic, logical test analysis scheme to assess machine operation from a simple sensor system and to be able to pinpoint parts and components needing replacement is provided by a series of first level of tests by the control to monitor components for receiving a first level ...
