Abstract: A coating for carbide substrates employs a nanostructured coating in conjunction with a non-nanostructured coating. The nanostructured coating is produced by the addition of a refining agent flow, particular hydrogen chloride gas, during deposition, and may be produced as multiple individual nanostructured layers varying functional materials in a series. The combination of a nanostructured coating and non-nanostructured coating is believed to produce a cutting tool insert that exhibits longer life. Pre-treating the substrate with a mixture of compressed air and abrasive medium prior to coating the substrate and post-treating the coated substrate with a mixture of water and abrasive medium after the coating process is believed to further enhance the wear resistance and usage life of the cutting tool.

Abstract: Rotary jet nozzle assembly (1) for pressure cleaning devices, comprising: a housing (2) extended along a first longitudinal axis (X) between an inlet (3) and an outlet (4) of a washing liquid, defining therein a containment chamber (5) of the washing liquid in fluid communication with the inlet (3); a support (10) rotatable within said containment chamber (5) and about the first longitudinal axis (X) due to the effect of the washing liquid coming from the inlet (3); a nozzle body (20) extended along a second longitudinal axis (Y) inclined with respect to the first longitudinal axis (X) and traversed by a delivery duct (28), the nozzle body (20) being associated with the support (10) and driven in rotation thereby; and a counterweight, integral with the support (10) and arranged in a position that is eccentric and opposite the nozzle body (20) with respect to the first longitudinal axis (X).

Abstract: A cleaning apparatus and system for removing debris from a surface of a plate or utensil. The apparatus has a cleaning area and a pair of brushes disposed in the cleaning area with the bristles of a first brush facing toward the bristles of the second brush so that debris is scraped off the surface as the plate or utensil is pushed through the bristles. The cleaning area may be defined by a container or an opening in a work surface. Brush mounting mechanisms mount the brushes to opposing sidewalls of the container or opposing interior surfaces of the opening. The brush mounting mechanisms and brushes can be cooperatively configured so the bristles of the brushes overlap each other where the plate or utensil will be pushed through the bristles. The mounting mechanism may be a clip that engages a sidewall of the container. The system includes the apparatus.

Abstract: An orthosis with controlled angular excursion can be positioned at the level of a joint or articulation of the human body. The orthosis includes an articulated joint with a basic structure designed to be positioned on the joint and also includes centrally, a pin with toothing located in a circular sector with predetermined width. The basic structure and the relative pin provided with toothing are equipped with a respective pair of rings, each of which has a substantially elongated shape. A hollow part, or slot, includes two straight sectors, of which at least one is provided with toothing with the same pitch as the toothing of the pin with which it engages. The pair of rings can, when in use, be simultaneously rotated around the pin, and are provided with slots which in turn include a tractor for the orthosis.

Abstract: Ultrasonic spray deposition (USD) used to deposit a base layer on the substrate, followed by chemical vapor infiltration (CVI) to introduce a binder phase that creates a composite coating with good adherence of the binder to the initial phase particles and adherence of the composite coating to the substrate, is disclosed. We have used this process to create coatings consisting of cubic boron nitride (cBN), deposited using USD, and titanium nitride (TiN) applied using CVI in various embodiments. This process can be used with many materials not usable with other processes, including nitrides, carbides, carbonitrides, borides, oxides, sulphides and silicides. In addition, other binding or post-deposition treatment processes can be applied as alternatives to CVI, depending on the substrate, the coating materials, and the application requirements of the coating. Coatings can be applied to a variety of substrates including those with complex geometries.

Abstract: A method for the purification of allopregnanolone is disclosed. Allopregnanolone prepared from isopregnanolone contains impurities such as triphenylphosphine oxide and other unknown impurities. To remove these impurities and purify allopregnanolone, the allopregananolone is dissolved in acetonitrile, and crystallized from the acetonitrile. The resulting crystallized allopregnanolone may then be re-crystallized from acetonitrile to further purify the allopregnanolone.

Abstract: The invention relates to an insert for a passport booklet data sheet, formed by a multilayer complex having at least a first layer and a second layer having a hinge that has a folding zone where the insert is intended to be sewn or stapled into a passport booklet, said second layer having, in combination, at least one layer of plastics material and at least one metal reinforcing layer that together form an extension which extends a certain distance beyond said folding zone of the hinge, so as to reinforce the resistance of said data sheet to being ripped out and torn with respect to the passport booklet, characterized in that said layer of plastics material and said metal reinforcing layer extend over the entire surface area of the insert.

Abstract: A straw inspection apparatus for inspecting whether or not a straw sheet is defective comprises: a main body for guiding the transfer of a straw sheet; a driving unit for transferring the straw sheet; a first inspection module for inspecting whether or not foreign materials are present in the straw sheet moving in the main body; a second inspection module for inspecting the exterior of the straw sheet; a controller for determining whether or not the straw sheet is defective based on the inspection results of the first inspection module and the second inspection module; and a cutting unit for separating the straw sheet which is determined to be defective.

Abstract: A physical configuration of multiple-layer coatings formed with at least one layer of coating containing cubic born nitride (cBN) particles with one or more layers in composite form containing cBN particles may have a thickness of each individual layer as thin as in the nanometer range, or as thick as in the range of a few microns and even up to tens of microns. The chemistry of the composite layer consists of any individual phase of (a) nitrides such as titanium nitride (TiN), titanium carbonitride (TiCN), and hafnium nitride (HfN); (b) carbides such as titanium carbide (TiC); and (c) oxides such as aluminum oxide (AI2O3) or any combination of the above phases, in addition to cBN particles. The coating or film can be stand-alone or on a substrate.

Abstract: The invention relates to a system for securing sleepers in a ballastless track formed by a base plate, sleepers and an interposed elastic intermediate plate, wherein the sleeper body comprises at least one through-hole, and the base plate comprises the corresponding blind holes in which a securing pin is embedded, to which a guide rod that can be inserted in the through-hole is joined, via which the sleeper is secured to the base plate in such a way that no additional pretensioning is added to that caused by the positioning of the sleeper thereon, and only a certain amount of vertical movement is permitted, forming a disassemblable assembly of the securing elements and the sleepers.
