Abstract: The present invention relates to a method and a device for clearing mines deployed on or in the ground using a mechanical demining vehicle operating on the rotary cultivator principle in a way that prevents major damage to the demining tool (6) or the engine (5 ). The basis of the present invention is that the demining tool (6) is enabled to deflect away from large mine detonations whereby the demining tool (6) moves in coordination with the engine so that neither it nor its drive function suffers any major damage.

Abstract: A method for deterring arboreal animals from climbing and reaching a bird feeder nesting box or elevated plant holder, supported atop a post set within the ground, includes the steps of providing a freestanding, non-rotatable hollow, longitudinally extending body and inserting the post supporting the bird feeder, nesting box or elevated plant holder conjunctionally therein. Alternatively, the bird feeder, nesting box or elevated plant holder may be directly supported atop the freestanding, non-rotatable, longitudinally extending body. The free standing, non-rotatable longitudinally extending body extends up from the ground, and is made of a minimal height and width, whereupon the arboreal animal will slide down the free standing, non-rotatable hollow, longitudinally extending body to a position where the arboreal animal is out of a jumping range to reach said bird feeder, nesting box or elevated plant.

Abstract: A groove is provided on an upper surface of a handgun slide, wherein the groove is enclosed on one end and open at the rear end of the slide. The groove, beginning at a predetermined point along the top and extending rearward to the end of the slide, has a front face and a rear opening. A small cylinder of tritium activated phosphor is installed in the front face of the groove and is longitudinally parallel to the device so that the end of the cylinder is visible to a holder of the device. Additionally, a second small cylinder of tritium activated phosphor is installed just below the rear opening of the groove. The second cylinder is parallel to the bottom of the rear opening so that the length of the cylinder is visible to the holder. Sighting is accomplished by aligning the first cylinder end with the bottom of a target and aligning the second cylinder length with the bottom of the first cylinder end in the standard “six o'clock” sighting position.

Abstract: An air gun trigger system, working in conjunction with an air gun, having a firing system, moving between a rear position in a ready state and a forward position for firing bullets, the air gun trigger system comprising: a holding element; a first trigger device; a second trigger device; and a driving unit. The holding element holds the firing system in the ready state and when triggered releases the firing system therefrom to move towards the forward position. The first trigger device is manually operated to trigger the holding element. The second trigger device automatically triggers the holding element and is driven by the driving unit. Thus the holding element is triggered to release the firing system from the ready state by either the first trigger device or the second trigger device. The driving unit causes a continuous movement of the second trigger device, resulting in fully automatic firing of bullets.
