An integrally formed angioplasty cutting device for balloon angioplasty of a stenotic lesion in a body vessel. The device comprises a distal collar and a proximal collar. The device further comprises at least one strut integrally formed with the distal collar and the proximal collar. At least one of the collars has a slot formed therethrough defining a C-shaped configuration. The strut is configured to be disposed at the stenotic lesion to engage the stenotic lesion for dilatation of the body vessel during angioplasty.

A process comprises (a) providing (1) at least one sample suspected of comprising at least one coliform strain, (2) at least one culture device comprising at least one culture medium that is hydrated or hydratable, and (3) at least one particulate concentration agent that is substantially optically transparent when in contact with the culture medium in the culture device when the culture medium is hydrated; (b) placing the particulate concentration agent in contact with the sample such that at least a portion of the coliform strain is bound to the particulate concentration agent to form coliform-bound particulate concentration agent; (c) placing the coliform-bound particulate concentration agent in contact with the culture medium; (d) incubating the culture device comprising the coliform-bound particulate concentration agent in contact with the culture medium, the culture medium being hydrated; and (e) optically detecting the presence of the coliform strain without separating the coliform strain from the particulate concentration agent.

A production process for producing high-purity silica from a crude silica source by means of fluosilic acid, including the steps of: (a) subjecting the crude silica souce and the fluosilicic acid to a reaction in a reaction stage, so as to produce silicon tetrafluoride and water; (b) selectively evaporating the silicon tetrafluoride with respect to at least a portion of at least one impurity derived from the crude silica source, and (c) reacting the silicon tetrafluoride with water to produce the high-purity silica, wherein the reaction stage (a) is performed at a temperature above 75° C.

A fairing drive assembly couples a flap assembly of a wing of an aircraft to a fairing of the wing. The fairing drive assembly may include a fairing cam including a first joint and a second joint, and a flap link pivotally coupled to the first joint of the fairing cam and the flap assembly. A fairing drive arm is pivotally coupled to the second joint and the fairing. The fairing cam is configured to rotate upon actuation of the flap assembly and deflect the fairing away from the flap assembly.

A speech therapy device configured to be placed in a mouth of a speaker. The speech therapy device includes a first bite plate and a second bite plate disposed opposite the first bite plate. The speech therapy device further includes at least one connecting member disposed between the first bite plate and the second bite plate. A method for using the speech therapy device is also provided.

A method for the preparation of Cinacalcet is disclosed comprising treating (R)-1-naphthyl ethylamine with an aromatic aldehyde to form (1R)-1-(2-naphthyl)-N-(aryl methylene)ethanamine derivative of Formula (IV), which is further treated with 1-(3-halopropyl)-3-(trifluoromethyl)benzene of Formula (V) to obtain an iminium salt of Formula (VI), followed by hydrolysis to obtain Cinacalcet free base.

The invention relates to a torque transmitting device comprising a torque input element (17a, 17b) and a torque output element (8) able to pivot about a shaft (X) with respect to one another, at least one elastic leaf (22), rotationally coupled to the torque output element (8) or to the torque input element (17a, 17b) respectively, the elastic leaf (22) being able to be elastically and radially supported by a supporting member (18) carried by the torque input element (17a, 17b) or the torque output element (8) respectively, the elastic leaf (22) being able to bend upon rotation of the torque input element (17a, 17b) with respect to the torque output element (8).

Thermosetting resins are provided that are toughened with an irradiated thermoplastic toughening agent and which have reduced levels of solvent-induced micro crack formation. The thermoplastic toughening agent is treated with a sufficient amount of high-energy radiation (e.g. electron beam or gamma rays) to cause a reduction in solvent-induced micro crack formation in the cured resin when compared to the same toughened thermosetting resin in which the non-irradiated version of the thermoplastic toughening agent is used.

A method for eliminating metal composites from a polycrystalline silicon cell piece, comprising the steps of: injecting current into the polycrystalline silicon cell piece under a certain temperature by means of an electric injection method, thereby eliminating the metal composites from the interior of the polycrystalline silicon cell piece; the present invention discloses a simple process, a short processing-time, a low manufacturing cost, and can easily be scaled for manufacture.

A stiffening device for a base frame is disclosed. The disclosed stiffening device comprises hydraulic jacks fitted with structural members of the base frame; strain gauges coupled to the structural members of the base frame, the strain gauges configured to detect deformation in the structural members of the base frame and generate first signals based on the detected deformation in the structural members; at least one signal conditioner unit coupled to the strain gauges to receive the first signals and generate second signals by performing any or a combination of amplification, filtering and conversion of the received first signals; and a hydraulic console configured to actuate at least one of the hydraulic jacks when value of received second signals is above a predefined threshold value. Upon actuation, the actuated at least one of the jacks stiffens at least one of the structural members of the base frame.
