摘要:
Garment (10) comprising means (20, 30) for active protection of the upper part of the body against falls and/or impacts with obstacles, in which a single active protection means (20, 30) extends from one side to the other of the chest above the sternum.
摘要:
A heating panel (11) for floors and/or for forming platforms, having at least one internal electrical resistance (20) which can be fed from outside through electrical conductors arranged inside the panel, characterised by comprising one or more connectors having terminals to which said conductors are connected.
摘要:
During the manufacture of slabs of stone or stone-like material using the technology which envisages preparation of a mix formed by a granular product and by a binder consisting of a hardening synthetic resin, vacuum vibrocompression of a layer of said mix and hardening of the resultant rough slab by means of a catalytic action and by heating, the slab is cooled to room temperature by directing onto both its surfaces a flow of cooling fluid, in particular air at room temperature, while controlling the flowrate of the air, so as to ensure gradual and controlled cooling, and supporting the slab in a static and perfectly flat condition. The device consists of a flat structure provided with a plurality of spacers (20) which keep the slab in a perfectly flat condition and allow the flow of cooling fluid to perform its action.
摘要:
End-of-travel device (10) for roller blind actuating systems, comprising a member (22) displaceable as far as an end-of-travel position (26), coupling means (20) in engagement with the displaceable member (22) and rotationally actuated by a motor, and lever means (40) for converting the displacement of the displaceable member (22) into activation of an end-of- travel switch (60). The lever means (40) comprise a movable member (50) pivotably hinged on a frame and engageable with pressure by the displaceable member (22) when its reaches the end-of-travel position (26). The member (50) can be engaged with an actuating member (58) of the switch (60) where an actuating member of the switch (60) is positioned radially with respect to the axis of displacement of the member (22).
摘要:
Guard structure (10) for protecting a lower limb, comprising a number of substantially rigid members (14, 26, 32), which are adapted to be removably and adjustably applied on to the thigh and the calf of the user. These rigid members are connected with each other in such a manner as to allow for the length of the entire structure to be adjusted in accordance with the actual length of the limb, in particular of the calf, while keeping the rigid members themselves joined with each other. The lower end portion of the structure, which is intended for wearing under the usual garment, is anchored in an adjustable manner to a containment shell (52) for a shoe (36).
摘要:
An apparatus for machining an article (L) in the form of a slab or the like comprises-in addition to a rotary tool (24) associated with a spindle (22)- a nozzle (26) ejecting water at very high pressure. Both the rotary tool and the nozzle are supported by a carriage (20) sliding along a beam (18) in turn sliding along two shoulders (14) in a perpendicular direction. In the working area (12) and above a tank (30) normally filled with water, the article (L) is supported in a horizontal position not only by an interchangeable grid (32; 52) , but preferably also by a disposable support (34) which prevent the rotary tool (24) from coming into contact with the grid. The disposable support is periodically replaced.
摘要:
A core, for example made of steel, is provided with a coating formed by an agglomerate obtained by means of hardening of a mixture comprising a granulated stone material, preferably of the type having a high hardness factor and light colour, and a hardening resin, preferably an epoxy resin. For the manufacture of the roller, a form work having a cavity for housing a core is prepared so as to provide an interspace which is filled with the aforementioned mixture, following which compacting of the mixture present in the interspace and then the resin hardening step are performed.
摘要:
The invention relates to a device for interrupting selectively a rotary translational movement, comprising a threaded elongated element (14; 14) and an element (112) having a female thread mating with the thread of the elongated element (14; 114), one of said elements (112, 14; 114) performing a translatory movement as far as at least a position defined by an end-of-travel stop (150) as a result of engagement with the other element, and said translating element being able to undergo momentary deformation upon reaching said at least one end-of-travel position (150) with the effect of being disengaged from the other element.
摘要:
While an article (12) made with fibres of inert materials bonded with resins, in particular a panel, is machined, the zone of contact between a swarf-removing tool (14) and the article (12) is sprayed with water. The dust and fine particles produced during machining operations are thus eliminated.
