摘要:
A multi-use pallet of the compact type for gathering refuse, rubbish and loose bulk objects from the floor or similar surfaces, comprising a gathering portion (2) developing in a principal plane (P) united with a handling portion (3) with a longitudinal axis (L) for being grasped by a user. The gathering portion (2) is united to the handling portion (3) by hinge means (10) and has stop means (15, 15') for selectively blocking the relative angle (β) formed between the longitudinal axis (L) and the principal development plane (P). The handling portion (3) comprises an essentially cylindrical body (8) with an external grip surface for the user and an internal cavity for the insertion of an elongated rod-like sleeve (9). The hinge means (10) comprise a pin (13, 13') inserted in respective adjacent elements (11, 12) of the portions (2, 3) for defining a connection pivotable between themselves.

Mobile barrier with anti-falling access particularly for lofts delimited by railings (P) with at least one open section for allowing loading/unloading of goods, comprising a bascule structure (2) contained inside the perimeter of the railing (P) and defining a space (V) which is openable outwardly for the transit and temporary confinement of the goods, means for connecting (6, 7, 9, 10) the structure (2) to the loft (S) adapted to allow movement between a first position, in which the transit space (V) is only accessible from the loft (S), and a second position, in which the space (V) is only accessible from the outside. In both positions the bascule structure (2) is adapted to shut the open section of the railing so as to define a permanent security barrier.
摘要:
An orthopaedic apparatus, particularly for the surgical correction of angular and longitudinal defects of the bones of limbs, of the femur and tibia type, comprising a longitudinal rod (2) externally positionable substantially parallel to a bone for correction, a first clamp (3) movably anchored to the rod (2) for supporting drilling guides for screws insertable in a proximal portion of the bone, and at least one second clamp (4) movably anchored to the rod for supporting drilling guides for screws insertable in a distal portion of the bone. The first and second clamps are orientatable and selectively blockable, before the surgical intervention, in predetermined angular positions with respect to the rod (2) corresponding to the angular deformations of the bone, and are repositionable with respect to the rod in correct angular positions after the osteosynthesis of the proximal and distal portions of the bone so as to eliminate the angular deformations of the bone.
摘要:
An intramedullary cavity nail for the treatment of proximal femoral fractures, comprising a solid elongated body having a proximal portion (2) with at least one hole for accommodating corresponding screws (9,10) for stabilising the femoral neck, joined to a distal portion (3) with at least one distal hole (16) for accommodating at least one diaphysis screw for stabilising the distal part of the femur. The proximal portion (2) has a substantially constant diameter (⌀ p ) adapted to be stably anchored in a relatively limited length bore of the femur for reducing blood losses, while said distal portion (3) has a substantially constant diameter (⌀ d ) which is less than that of said proximal portion for being easily inserted in the medullary canal of the femur without any drilling. The proximal and distal portions (2; 3) are substantially rectilinear and form between themselves a predetermined deviation angle (β) in a lateral plane. The proximal portion (2) has a pair of inclined holes (7, 8) adapted for accommodating respective cephalic screws (9, 10) for the fixing of the femoral head.
摘要:
A compact external fixator for the treatment of fractures in small bones and in children comprises a pair of clamps (2, 3) for bone bolts (V) connected by means of corresponding ball joints (5, 6) to a central body (4) comprising at least one male member (7) and one female member (8) which are joined telescopically. One member (7) is made of a material which is highly transparent to X-rays, the other (8) of a rigid substantially radio-opaque material having walls of a minimum thickness. Anti-rotation means between the male (7) and the female (8) telescopic member are provided; transverse eccentric pins (34, 35) are housed in each clamp to act on corresponding locking blocks (28, 29) which immobilise the balls (24, 25) of the joints. A tensioning device (36) applicable to the fixator (1) comprises hook formations (49, 50) which can be coupled to ends of the telescopic members (7, 8) and are attached to the ends of counter-threaded rods (43, 44) screwed in the threaded portions of a rotatable sleeve (37). The fixator permits full X-ray examination of the fracture even through the central body, and is light and small as a result of the arrangement of the locking means for the joints within the clamps.
摘要:
A refuse trituration-compaction machine including: a rotating loading inlet (21) with a cylindrical portion and a pivoting sack-pushing flap for pushing material into the machine; a horizontal conveyor belt (5) for transporting the refuse from the loading inlet to a rotating cutter element (30) in which the conveyor belt is provided with a pivoted portion arranged above the rotating cutter element for allowing material blocked on the rotating cutter element to pass under the upwardly pivoted belt portion; a pivoted presser plate (20) movable between a work position for compacting refuse in a containment bin (18) and a non-working position arranged distally from the rotating cutter element such that material may fall directly from the rotating cutter element into the containment bin (18); a complementary cutter element (26) removably arranged adjacent the rotating cutter element (30) with spaced-apart fixed blades for arrangement between a cutter blades of the rotating cutter element spaced apart by intermediate spacer disks, and a presser device (28) slidably mounted on the complementary cutter element (26) for pressing refuse material between said fixed blades and said cutter blades, and including plates (28) connected to a movable end portion of the presser device and extending for arrangement between the cutter blades of the rotating cutter element, and raised portions (31) provided on the intermediate spacer disks for grazing the fixed blades of the complementary cutter element; and a user control system including a magnetically coded card identifying each user of the machine, a magnetic card reader for reading the magnetically coded card, and a computer system for processing data including refuse amount data and time of conferment data related to each specific user.
