Abstract: An extruder, granule feed, and liquid additive dispenser system for 3D printers, having a mobile print head (1) with a substantially vertical extruder barrel (17) and a throat (18) which, at the upper area whereof, includes a mobile funnel-shaped hopper (10?) for the receiving of the granules (2) and a rotating internal worm (19). The mobile hopper (10?) presents curved indentations (28) that progress inward in the rotational direction of the worm, seeking langency to the mouth (29). The worm (19) includes, as an extension to its thread (26), a drag shovel (20) complementary to the mobile hopper (10?) with a sloping internal thrust face (27) that links with its cavity (25) and draws inward the granules contained in the hopper (10?) via the indentations.

Abstract: An anchor assembly (1) that has two hooks (2, 3) pivotably connected by a rotary shaft (4). A distal end of each hook has a tooth (21, 31) and the other end, a slot (22, 32). The assembly has an insertion configuration (P1) where hooks (2, 3) are superposed, and a securing configuration (P2) where teeth (21, 31) are separated whereby hooks (2, 3) project to remain retained in an inner support surface (51).

Abstract: The invention relates to a scissor-type securing element (1) comprising two hooks (2, 3) pivotably connected together by a rotary shaft (4), a distal part being defined in each hook (2, 3) on one side of the shaft (4) and a proximal part being defined on the other side of the shaft (4), each distal part being provided with a tooth (21, 31) and each proximal part being provided with a penetrating slot (22, 32). According to the invention, the securing element has an insertion configuration (P1) in which the hooks (2, 3) are superposed, and a securing configuration (P2) in which the teeth (21, 31) are in a more separated position and the hooks (2, 3) project so as to remain retained in an inner support surface (51) of a case (5).

Abstract: A scope formed integral with a mount which may be used on rifles or similar weapons utilizing telescopic sights.

Abstract: A novel, moving target system for the improved practice of hunting and improved shooting skills. The target may be comprised of one or more knockdown target sections moving along a track assembly on a carriage and may be preprogrammed to simulate random, realistic behaviors including running, walking, or grazing to simulate hunting game. The target may be programmed to adjust its speed randomly or in reaction to a gunshot or strike on the target or may be programmed to pause or randomly reverse direction, approximating the random behavior observed in hunting targets. The knockdown sections will react to a strike with preprogrammed behavior as described above, giving immediate feedback to the shooter.

Abstract: A novel, adjustable locking windage and elevation knob assembly for the improved accuracy of scopes wherein an adjustment turn knob may be raised from its locked position to rotate freely for desired windage or elevation adjustments and thereafter be pushed back down into a locked position.

Abstract: An evaporative cooling system is disclosed. The system comprises a housing comprising a base sheet and a side wall and having at least one opening fitted with an evaporative medium pad and an exhaust vent. The system also comprises a pump configured to disperse water over the evaporative medium pad. The system also comprises a pan configured to receive the water. The pump is configured to cooperate with the pan to recirculate the water. The system also comprises an exhaust fan configured to draw air into the housing through the evaporative medium pad and out the exhaust vent. The side wall of the housing is at least partially pressed into the base sheet of the housing to form a joint having a corrosion resistant coating. A kit for assembling an evaporative cooling system is also disclosed. A method of making an evaporative cooler is also disclosed.
