A method and apparatus relating to a biocompatible soft tissue implant is disclosed. The implant, in the form of a prosthesis, is constructed of a knitted pile mesh material arranged into either a 3-dimensional structure or a planar shape or structure. The material or fabric includes a plurality of filament extensions projecting outwardly therefrom. The filament extensions can be radially projecting looping filaments from one or more rows of the knitted pile mesh material. The combination of the filament extensions with the 3-dimensional structure results in the biocompatible implant having a structural resistance to hinder anticipated crushing forces applied to the implant, and also provide a suitable 3-dimensional structure for promoting rapid tissue in-growth to anchor such implant without migration and strengthen the repaired tissue area.

Submerged combustion systems and methods of use to produce foamed glass. One system includes a submerged combustion melter having an outlet, the melter configured to produce an initial foamy molten glass having a density and comprising bubbles filled primarily with combustion product gases. The initial foamy molten glass is deposited directly onto or into a transport apparatus that transports the initial foamy molten glass to a downstream processing apparatus. An intermediate stage may be included between the melter and the transport apparatus. One intermediate stage is a channel that includes gas injectors. Another intermediate stage is a channel that produces an upper flow of a less dense glass and a relatively more dense glass lower flow. The upper flow may be processed into foamed glass products, while the more dense flow may be processed into dense glass products.

Some embodiments provide a drum structural framework comprising a top shell mount, bottom shell mount, rod holders, and tension rods. The top shell mount and bottom shell mount are mounted to either ending edge of a drum shell disposed between the two mounts. A first set of the rod holders are coupled to the top shell mount and an aligned second set of the rod holders are coupled to the bottom shell mount. The tension rods link the two sets of rod holders without hindering resonance of the drum shell. Tuning assemblies on the rod holders adjust the distance separating the top shell mount from the bottom shell mount, thereby controlling the force imposed on the drum shell. Each rod holder includes one or more dampeners that isolate energy passing from the drumhead to the shell from also reverberating throughout the structural framework of the tension rods and rod holders.

According to typical inventive practice, precursor particulate is pressed and / or caste and / or molded and / or machined, thereby producing a porous green body of a desired shape. A gas is brought into contact with the porous green body so that, via reaction bonding between the gas and the porous green body, the porous green body becomes a porous reaction-bonded ceramic preform, geometrically corresponding to the porous green body. One or more infiltrant materials, at least one of which is glass or polymer, is / are caused to infiltrate the pores of the RB ceramic perform. The infiltrants are selected from glass, polymer, and metal. The infiltrated preform is permitted to cool and solidify, resulting in an embodiment of an inventive non-ceramic-infiltrated reaction-bonded-ceramic structure. Because of their potential material attributes such as strength, energy dissipation, and low density, the present invention's non-ceramic-infiltrated reaction-bonded-ceramic structures are especially favorable for inclusion in personal / personnel ballistic armor systems.

Electric vehicles usually inherit a chassis of a pressed steel construction from a conventional vehicle design. This imposes a substantial weight penalty on the vehicle. We disclose a chassis element for a vehicle, formed of an outer skin material, an inner core material enveloped by the outer skin material, and at least one array of aligned fibres, and comprising a restraint for an electrical battery adapted to locate the battery over the at least one array. There can be multiple arrays of aligned fibres, preferably disposed at a transverse angle relative to each other of less than 90°. We particularly prefer three arrays of aligned fibres, which can be disposed relative to each other at an angle of 60°. The fibres can be disposed within the skin material. The restraint ideally comprises an upstanding wall which will serve to confine the batteries in the event of a collision or other sudden movement, but will allow them to be replaced easily for maintenance purposes or to replace an exhausted set of batteries with a charged set. Alternatively, the restraint can comprise an attachment point for the battery. The core material is preferably less dense than the skin material, thereby allowing the composite element to have a light weight and a high rigidity. The application also relates to a vehicle comprising a chassis, an electric motor, a chassis element as set out above, and electrical connections from the battery to the motor, wherein the chassis element is attached to the chassis via removable fixings extending through the fixing points of the chassis element into corresponding fixing points on the chassis

Electrospun materials are fabricated using air-flow impedance technology, which results in the production of scaffolds in which some regions are dense with low porosity and others regions are less dense and more porous. The dense regions provide structural support for the scaffold while the porous regions permit entry of cells and other materials into the scaffold, e.g. when used for tissue engineering.

An annular design heat exchanger is formed from an arrangement of wedge-shaped stacks of wafers. Each wafer includes sheets of material separated by peripheral and supporting walls that define interior flow channels through which a first fluid can flow. Holes in the sheets provide inlets and outlets to the channels, and walls surrounding the holes mate with neighboring wafers in the stack, forming integral inlet and outlet manifolds, while ensuring uniform spacing between the wafers. A second fluid can flow around the manifolds and through the spaces between the wafers in a counterflow pattern. In the annular assembly, the manifolds are oriented substantially axially, and the flow channels are oriented substantially radially. The heat exchanger can be formed from a ceramic material, and can be incorporated into an engine assembly or a heat-recirculating combustor.

The invention discloses a method for preparing a copper alloy additive material based on electron beam powder laying forming. The method comprises steps that an obtained STL format file is inputted into rapid forming software of a molding machine; a layer of copper alloy powder is spread on a forming platform in advance, and an electron beam preheats a substrate and a powder bed; the outline is melt, and the electron beam scans the boundary in a spotted mode; the cross section is melt, and an electron beam linear scanning cross-section beam current value is increased from 5.5 mA to 7 mA over time; the process is repeated till manufacturing of copper alloy parts is completed. The method is advantaged in that the method is the additive material manufacturing technology utilizing powder laying electron beam selective zone melting, due to substrate and powder bed preheating and beam incremental scanning modes of the electron beam before melting, warping and non-dense organization caused bythe residual stress in the forming process are effectively reduced, the phenomenon of overheating or spheroidization of formed parts is avoided, and thereby high quality and efficient additive material manufacturing of the copper alloy is achieved.
