Abstract: This patent defines a device for automatic calibration of optical sights for firearms. Only one shot has to be fired to achieve this. The device can be integrated with an optical sight or fitted as a separate unit mounted on the sight. The device consists of a digital camera (e.g. CCD), a beam splitter, a microprocessor including a memory for camera images and computer software, servo motors including a gear mechanism, an electrical switch and light emitting diodes and a shot detecting sensor. In the digital sight application, the device also includes a display unit while servo motors, gear mechanism, light emitting diodes and beam splitter are excluded. The calibration procedure involves firing a round at a target consisting of a rectangular white surface on a dark background at the chosen range. The camera saves the last image immediately before the firing moment and compares the cross-hairs position with that of a following image from which the projectile point of impact can be found. After calculations that determines the error between point of aim and the projectile point of impact—which are based on image analysis only—the position of the cross-hairs is adjusted by servomotors to align with the detected projectile impact point position. In the digital sight application, the cross-hairs is simply re-drawn at the new correct location on the display. The weapon and the optical sight are now calibrated at the chosen range.

Abstract: The invention provides a flow distribution system for pressure medium for steering hydraulics of machines with two or more pumps. A flow distribution valve controlls pumps of a feed pressure medium via the distribution valve through the steering valve to the selected operative unit and, on the other hand, to what extent the output of the pumps is directed to the tank channel, and in which system a coil spring is arranged as acting upon one end of the flow-control shaft in the flow distribution valve, which spring presses the shaft to one of its extreme positions, in which extreme position all pumps of the system feed pressure medium through the flow distribution valve via the steering valve to the operative unit. The invention is characterized by a force determined by the magnitude of the loss of pressure on the output side of the steering valve which is arranged as acting upon the flowcontrol shaft against the spring force of the coil spring whereby the position of the flow-control shaft is determined by means of the pressure difference between the pressure in the pressure medium coming from the flow distribution valve to the steering valve and the pressure in the pressure medium in the working cylinder connected to the steering valve.

Abstract: A dry method of removing pyrite from mineral coal in which the coal is mill-dried in a milling gas stream and the milled product is subjected to classification to recover a predominantly coal combustible fine fraction and a gravel or coarse fraction containing mining detritus, pyrite and coal. The gravel or coarse fraction, according to the invention, is subjected to density separation in whole or in part before being recycled to the milling stage and the density separation separates a light coal fraction from a heavy fraction containing the pyrite and detritus. This coal fraction can be returned to the miling stage while the heavy fraction can be subjected to further separation to recover the pyrite for other use or treatment.
