Title: Helix with wings disposed planetarily about its axis of rotation on a track of the same or of a different radius and on the same or on a different transverse plane
Inventor: DIAMANTOPOULOS PANAGHIOTIS J
IPC: B63H1/26
Filed: 1985-03-05
Abstract: A propeller for ship propulsion consists of trapezoidal helically shaped wings (3) which are arranged planetarily about its axis of rotation advancing axially in a screwing mode. The wings of the propeller, constituting a portion of a complete spiral of a screw, are disposed at a certain distance (radius) from their axis of rotation, on the same or on a different perpendicular or transverse plane to the axis of the hub (1) and at the same or a different radius, being mounted on the hub by means of arms (6). The wings (3) tend to momentarily (instantaneously) immobilize a mass of water in which the propeller is operating, thus attaining a support on a solid and steady (or almost solid and steady) body/mass and consequently causing axial advance in a screw-like manner like a worm screw. <IMAGE>

Patent PT-83542-B (PT)
IPC: A63H27/08
Filed: 1986-10-14
Abstract: A toy accessory for a kite comprises a slider intended to ride up the string of an airborne kite. The slider comprises a frame (3, 4, 5, 6) intended to be suspended from the kite string by pig-tail eyelets (7, 41). The front eyelet (41) forms the trigger of a latch mechanism including a cranked wire element having an intermediate limb (43) slidable longitudinally in holes (15, 8) in the frame, and a sear (46) slidable in hole (9) in the frame. The sear (46) latches a lever (27) in the position shown, in which it holds a pair of pivoted wings (1) in their operative spread position via ties (47), and, via a spring (26), holds a pivoted clip (23) in its uppermost position to trap a folded toy parachute between the frame member (5) and the clip (23). The slider is propelled up the kite string by wind pressure acting on the wings, until the front eyelet (41) strikes a stop on the kit string. This causes the wire element, and therefore the sear (46), to slide back, the lever (27) is released to pivot anti-clockwise, permitting the wings (1) to pivot forward to a folded position under the effect of an elastic band (40), and releasing the spring (26), allowing the clip (23) to hinge down and release the parachute. With the wings folded, the slider slides back down the kite string. The slider is then reloaded, and the latch mechanism reset, ready for a further ascent.

IPC: A01G23/06
Filed: 1988-03-30
Abstract: The invention consists of a tool for uprooting brushwood and shrubs, whose configuration starts from a head for hitching onto a driving tractor, bearing two side plates (2) attached to the hitching head, and on the lower edge of those plates is attached a dettachable shovel (4). The upper portion of these plates is prolonged to form a backward projection, to link the end of the hydraulic cylinder (3), the free end of whose rod links between the lower ends of a pair of arms (8) that, on their upper ends, are also linked that extend from the plates to which the shovel is attached, backwards and in a sloping manner. The tool also has means to disengage any shrubs or branches that may remain attached to the shovel after uprooting, and a set of claws (12) to secure the tool into the ground and stabilize it during the performance of its work. A second variation of this tool features a second shovel (22), installed facing the first shovel, so that betwen them both they encompass tree-trunks (25), to uproot and lift them.

Abstract: An expansion dowel is proposed which has an expansion cone (4) which can be drawn into an expansion sleeve (5), a sliding sleeve (8) of plastic or the like being arranged, according to the invention, between the expansion cone (4) and the expansion sleeve (5). During the expansion process, a part of the sliding sleeve material is crushed by the expansion sleeve (5) over the cone surface of the expansion cone (4), so that the pores of the metallic surfaces of the expansion cone (4) and of the expansion sleeve (5) abutting onto one another are clogged by the material of the sliding sleeve (8). In this way, good sliding characteristics are achieved between the expansion sleeve (5) and the expansion cone (4), and a correspondingly good subsequent expansion capability.
