The invention relates to a flexible structure, a hinge and a shutter comprising such flexible structure. The invention further relates to a mobile communications apparatus and a mobile telephone comprising such hinge or shutter. The flexible structure comprises a plurality of elongated bars having a length axis and being connected to each other, wherein:the bars are arranged mainly parallel to each other,each bar has a first end part, a second end part and a middle part between the end parts,at least two neighboring parallel bars are connected to each other by a connector at their point of connection.At least some of the parallel bars are elastic in such a way that the first end part and the second end part of one bar are arranged rotatable in relation to each other around the length axis of the bar.

The invention relates to so-called scanning tips of probes necessary for scanning a measured object, in particular in scanning force microscopes and other scanning microscopes, so-called scanning probe microscopes. The possible resolution of such microscopes depends primarily on the fineness of the tip, i.e. its curvature or radius being as small as possible. According to the invention, a photostructurable material, e.g. a photosensitive resists, serves as the material for the scanning tip which is exposed via a mask and is subsequently developed / hardened in a manner known per se. The unexposed parts of the photosensitive resist are removed as usual. By the shape of the exposure mask, the preferably directed exposure of the photosensitive resist, and the subsequent hardening, a tip is formed preferably laterally on or at a carrier, usually made from a different material, which is provided with a very small radius, thus very well suitable for scanning probe microscopy and similar applications. By an appropriate selection of the mask and / or the exposure angle, the geometry of the tip can be controlled, in particular its bending radius and edge angle, for other applications as well, e.g. for measuring scanners or profile meters.

An apparatus and related method for the recovery and the pneumatic transportation of dust coming from a filtration system provided with a particulate collection hopper. The apparatus comprises:an intermediate chamber for the passage of the particulate towards the evacuation means; andshutting means for a bottom opening (AP1) of said hopper. The apparatus is characterized in that the shutting means comprise, in turn, a shutter moved according to an arrow (ARW) by the action of intermittent pressurized air that flows in a control conduit forming part of said shutting means. Furthermore, the evacuation means comprise elements, specifically a nozzle aligned with a Venturi, to produce a pressure drop in the intermediate chamber.

Arm-rest, adjustable in inclination, in particular for vehicles, comprising: —a fixed part 2, intended to be connected to the frame of the vehicle; —a movable part 3, hinged to the fixed part 2 around a rotation axis X by —hinging means 10, 43, 53 to move between a lowered angular position and a raised angular position; and —a system for adjusting the inclination of the movable part 3 between the aforesaid lowered position and the aforesaid raised position. The invention is characterized by the fact that the system for adjusting comprises at least one freewheeling bearing 20, chosen from the rolling-contact or cam type, associated to the hinging means 10, 43, 53 so as to allow the movable part 3 to rotate around the axis X only in the direction of rotation which from the lowered position leads to the raised position. The system for adjusting also comprises releasing means which act on the hinging means 10 and are able to liberate the rotation, of the movable part 3 from the raised position to the lowered position.

A choke valve for an intake manifold with a retracting tumble system for an engine provided with a number of cylinders, the choke valve being adapted to vary the passage section of the air through an intake duct which connects each cylinder with the intake manifold and is regulated by at least one intake valve; the choke valve comprises a butterfly mounted to rotate about an axis of rotation disposed transversely and externally with respect to the corresponding intake duct under the thrust of a corresponding rotary electric motor which comprises a stator and a rotor housed directly in the butterfly.

A muscle-building agent comprising a whey protein hydrolyzate having a molecular weight distribution of 10 kDa or less, a main peak of 200 Da to 3 kDa, an average peptide length (APL) of 2 to 8, a free amino acid content of 20% or less, and antigenicity equal to or less than 1 / 100,000th of that of ²-lactoglobulin is provided. The whey protein hydrolyzate is very safe, exhibits high transparency when dissolved in water, has low bitterness, can be used for an arbitrary product, and exhibits a muscle-building effect.

An optical gas detector (20) in metal or other suitable material, comprising a cup-shaped body (1), with upper mouth (9) closed by a lid (2) the bottom of which (8) is flat and provided with a plurality of through holes (15) variously arranged, which place said detector (20) in communication with the outside environment, and inside which an IR source (10) and an IR analyser (11) are placed, borne by an overlying circuit board (12). The inner lateral surface of the body (1) forming a first reflector wall (6) having a regular or irregular annular extension and defining, in conjunction with a second convex or concave reflector wall (7, 7′) of a shaped appendage (5) and with one or more reflectors (3, 3′, 21, 22, 23,24,25) pre-inserted and positioned in the body (1), a multiplicity of geometrically alternative optical paths (4, 4′, 4″, 4′″) of the electromagnetic radiation emitted by the IR source (10) and detected by the IR analyser (11).

A car comprising a car body and a rear spoiler that projects from the outline of the car body to deflect the air flow upwards so that the air flow skims over an upper surface of said rear spoiler. The rear spoiler comprises a through aerodynamic duct, which starts in an inlet opening arranged in correspondence with an initial end of the rear spoiler and ends in an outlet opening arranged in correspondence with a final end of the rear spoiler, so that a part of the air flow hitting the rear spoiler flows above the rear spoiler, skimming over the upper surface of the rear spoiler, and the remaining part of the air flow hitting the rear spoiler flows through the rear spoiler crossing the aerodynamic duct.

A method for production of an eyeglass temple, the method including an injection of a first material into an injection molding tool upon forming an eyeglass temple main part with a main body and an inclination bearing body, and an injection of a second material into an eyeglass temple adjustment part cavity of the injection molding tool upon overmolding at least partly the inclination bearing body to form an eyeglass temple adjustment part, which is penetrated by the inclination bearing body and pivotable in relation thereto, after the first material has cured at least partly, and a removal of the eyeglass temple, which is in an eyeglass temple injection molding position, from the injection molding tool when the first material and the second material have cured at least partly.
