The present invention relates to methods for producing nanoparticle and microparticle powders of a biologically active material which have improved powder handling properties making the powders suitable for commercial use using dry milling processes as well as compositions comprising such materials, medicaments produced using said biologically active materials in particulate form and/or compositions, and to methods of treatment of an animal, including man, using a therapeutically effective amount of said biologically active materials administered by way of said medicaments.

A system for treating infectious waste is provided that employs a medical waste handling and shredding sub-system that feeds partially processed waste to an oxidizer to eliminate potential airborne infectious waste prior to transforming the medical waste into useful co-products. Medical waste is transformed into value added products including hydrocarbon based gases, hydrocarbon-based liquids, carbonized material, and recovered precious metals and rare earth materials in a system having as its transformative element an anerobic, negative pressure, or carbonization system. With medical waste as a feedstock for the production of valuable products, an economically viable and environmentally more responsible alternative to traditional methods of medical waste treatment is realized.

There is provided an impact grinding assembly. The assembly, according to one aspect, includes a pair of conveyors for conveying at least partially unground material. Each conveyor has a lower portion and an upper portion which is spaced-apart above its lower portion. The assembly includes a pair of vibrating impact plates aligning below the upper portions of respective ones of the conveyors to receive the at least partially unground material. A first one of the impact plates operatively directs material thereon to the lower portion of a second one of the conveyors. A second one of the impact plates operatively directs material thereon to the lower portion of a first one of the conveyors. The impact grinding assembly may further include a material-separation assembly for removing material from the conveyors which has a particle size no greater than a desired particle size.

Each of the plurality of interchangeable milling heads further includes an adaptor unit configured to connect the milling head to the connecting unit and for converting the range of motor characteristics of the driving motor into the milling driving characteristics of the connected interchangeable milling heads.

An adapter has a body cylindrical on one end and having a shape of a regular polygon on the opposite end, with an outer diameter, a height, and a central axis, a first counter-bore concentric with the outer diameter on the cylindrical end, the first counter-bore having an internal thread compatible with a thread on a neck of a conventional Mason jar, and ending at a horizontal shoulder, a second counter-bore from the end having the polygonal shape to a depth, ending in a second horizontal shoulder, the second counter-bore having an o-ring groove implemented on an inner diameter of the counter-bore, and a through bore concentric with the central axis passing through the adapter and providing a common inner diameter through the first and the second horizontal shoulders.

Precursors and methods for manufacturing perforated composite parts are disclosed. An exemplary precursor (19) comprises structural fibres (24,28) embedded in a cured matrix material (24,26) and interposed between two removable plies (20). The precursor may also comprise a sacrificial fibre (28) extending through the removable plies (20), the matrix material (24,26) and between the structural fibres (24,28). An exemplary method comprises removing the removable plies (20) from the precursor (19) and removing the sacrificial fibre (28) from the precursor after removing the removable plies to form a through hole in the precursor (19) at a location of the sacrificial fibre (28).

Non-limiting embodiments of the present disclosure relate to a method comprising: obtaining asphalt shingle waste (ASW) and performing grinding, screening, and separating steps on the ASW. In some embodiments, granules are removed from the ASW. In some embodiments, the method transforms ASW into ASW powder. In some embodiments, the ASW powder is formed into a plurality of briquettes. In some embodiments, at least one of: the ASW powder, the plurality of briquettes, or any combination thereof is fed into a mixing process that results in an ASW powder filled coating.

A device for comminuting ore and/or slag is contemplated. The device may be comprising an ore feeding unit for feeding ore which is to be comminuted to a first pulverizer, said first pulverizer being composed of at least of two comminuting elements which can be moved relative to each other, said elements forming together at least one comminuting space for the ore which is to be comminuted, such that, by a relative movement in the form of a rotation about the rotational axis of at least one of the two comminuting elements the ore which is to be comminuted is at least partially pulverized. One or more accelerating elements, in particular protrusions, are provided on at least one of the comminuting elements, said accelerating elements being arranged in particular on the end face of at least one of the two comminuting elements and accelerating and comminuting the ore to be comminuted by the rotation of one of the two comminuting elements. An intermediate space is provided between the two comminuting elements and/or in at least one of the two comminuting elements, through which space the pulverized ore, during the rotation, is transported from the center of rotation toward the outside and away from the two comminuting elements. At least one of the two comminuting elements is operatively connected to a hydraulic spring pressure device, said hydraulic spring pressure device being designed such that the comminuting element to which it is operatively connected is variably resiliently mounted in the direction of the other comminuting element depending on an adjustable hydraulic spring pressure control unit.

A specimen extraction kit includes a flexible tubular container configured to contain an extraction liquid, two holding portions opposed to each other and arranged at opposite sides of the tubular container, a coupling portion that couples the opposing holding portions, and a bending rib arranged on each of the opposing holding portions and configured to bend the tubular container and an extraction subject.

A hydrate production apparatus according to the present invention comprises: a main body unit having a reaction space in which a hydrate is produced therein; an inlet pipe unit connected to one side of the main body unit so as to introduce, into the reaction space, a host material and a guest material for producing the hydrate; an outlet pipe unit connected to the other side of the main body unit so as to discharge the hydrate produced in the reaction space to the outside; and a pulverizing device unit provided inside the reaction space so as to increase a reaction area for producing the hydrate by pulverizing, into fine-sized particles, an object to be pulverized, which is at least one of the introduced host material and guest material.
