Abstract:
Disclosed is a rubber composition for flexible coupling. In particular, the rubber composition for flexible coupling is prepared by mixing a filler including an HNBR alloy and carbon blacks having different average particle diameters with a hydrogenated acrylonitrile-butadiene rubber such that performance deterioration due to hydrolysis can be prevented even in hot and humid environments and the rubber composition has superior heat resistance and improved mechanical strength.

Abstract:
A minimally invasive lithotripsy device; for fragmenting calculi stones formed in the body (such as in the kidney, urethra, gall bladder and salivary glands) by means of vibrations and performing the cracking operation within the body; for rupturing foreign objects with the aim of curing cancerous cells and tumours; for treating fractured and broken bones and hence easing the pain caused by such reasons. The lithotripsy device serves to break the targeted mass/stone by a nail, according to which method a hammer, that moves by means of pressurised air, applies systematic strikes on the nail. The device acquires a mechanism which serves to release the air, in front of the hammer as it moves forward, and at the back of the hammer as it is reset backwards, out to the atmosphere while it incorporates a handling equipment.
Abstract:
A uniform heating assembly including at least one first insulative substrate, at least one first common terminal, at least one second common terminal and a multiplicity of conductive filaments at least partially embedded in the at one insulative substrate and extending at least mainly along both electrically parallel and geometrically parallel paths between the at least one first common terminal and the at least one second common terminal.
