Abstract:
The present patent application for industrial invention relates to a "cushioned parachute" for rolling shutters or blinds, in which the kinetic energy of the shutter during its uncontrolled descent is dissipated by deformation of elastic organs (6) compressed by a rotary ring (2) provided with one or more external facets (5) and driven into rotation by a rotor (1 ) coupled with the winding shaft of the shutter only in case of excessive rotational speed of said shaft.
Abstract:
A fluid mixer comprising a tank designed to contain the fluid to be mixed, a rotary shaft (1) that goes through a hole (22) obtained on the wall (2) of the tank, generating a channel (23) in which the fluid enters from the tank towards a chamber (24) outside the tank, in which the shaft (1) rotates and a seal unit designed to prevent the fluid from seeping out of the chamber (24) is disclosed. The said seal unit comprises a first seal ring (6A) mounted on the rotary shaft (1) and a second seal ring (6B) mounted on a support flange (4) fixed to the wall (2) of the tank, in such a way that the first seal ring (6A) slides in close contact with the second seal ring (6B) preventing the passage of fluid outside the chamber (24).
Abstract:
A walker (1) is disclosed, which comprises a base frame (20) supported by wheels (22) and support rods (3, 4) mounted on the said base frame (2) to support at a suitable height support means (7, 8) designed to support the patient during walking.The support rods (3, 4) are hinged mutually and to the base frame (2), in such a way to go from the operating position, in which the support means (7, 8) are at a suitable height to support the patient, to a minimum-volume position, in which the support means (7, 8) are near the baseframe (2).
Abstract:
The present invention relates to a laminectomy forceps that comprises a cleaning device with sliding rod inside the tray of the forceps, in such a way to remove the bone fragments that get stuck in the point of the tray.
Abstract:
The present invention relates to a pair of spectacles of the type comprising a partially rigid structure (22) designed to support a pair of lenses (20, 21 ) and a rim (1) provided at least with one frame (4) associated with two side-pieces (2, 3) by means of rotation, in which the structure (22) is coupled with the frame (4) by means of translation with the structure (22) in oblique position with respect to the normal operating condition and is held in place by means of rotation around its axis until the position that corresponds to the normal operating condition is achieved.
Abstract:
The present invention relates to a machine used to clean destalked grapes, being composed of a frame (T) that supports a screening and feeding belt (1), which is provided with a series of identical meshes (1a) and is wound on a parallel pair of movement and support rollers (2) with horizontal axis, of which one is a driving roller and one is a driven roller.
Abstract:
The present invention relates to an abrasive tool, of the type suitable to be mounted on a machine tool, comprising at least a bearing structure with abrasive material, the said bearing structure being provided with at least a grid (6) with abrasive material, the grid (6) partially protruding or emerging from a body (7) without abrasive material.
Abstract:
The present invention relates to a system used to feed WC flushing tanks (C) with recycled water collected in a tank (1) in which the water coming from the sink (L), other sanitary fittings and household appliances (LB) is drained; it being provided that, in case of absence or draining of the recycled water reserve, the same system is capable of favouring the feeding of the flushing tanks (C) with "clear" water normally supplied by the domestic water network (8).
Abstract:
The present invention relates to a submersed mixer for wastewater and treatment tanks, which comprises a seal chamber (5) obtained between the mobile part (6) associated with the propeller (1) and the fixed part (7) associated with the case (4) of the motor, in which the seal chamber (5) ends into the external environment (8) with an annular passage (9) and has a decreasing height away from the rotation axis of the propeller.
Abstract:
The present invention relates to a box (1) for disposable cotton buds characterised in that it is associated with one or more containers (5) for cosmetic, hygienic and/or sanitary products in fluid or semifluid state, each of them being provided with a hole (6) used to deeply insert one of the cotton buds inside the corresponding container.
