A tester for bonded composite materials uses a magnetic source to generate a response signal from wires infused in an adhesive used between layers of the composite material. Acoustic or magnetic response signals, separately or in combination, can be received and analyzed to detect stresses in wires indicative of voids in the adhesive or other defects affecting the bond quality between layers of the composite material.

A universal rotating chuck system capable of accommodating multiple small-batch or one-off machining jobs, involving workpieces of different diameter and composition, comprises a rotating chuck having multiple jaws that may be adjusted positionally inward or outward towards the longitudinal centerline of the workpiece or removed entirely. The chuck is rotated by a dual-motor system driving an inner and outer shaft, where the inner shaft is selectively coupled to the outer shafts to rotate independently and adjust the jaws, or rotate alongside the outer shaft to rotate the chuck. In operation, the system is capable of conducting numerous machining operations independent of direct user intervention, including loading/unloading workpieces, loading/unloading tools, measuring tools and workpieces for quality control, and storage.

A packaging material for a power storage device has a structure in which at least a base material layer, a first adhesive layer, a metal foil layer provided with an anti-corrosion treatment layer on one surface or both surfaces thereof, a second adhesive layer or an adhesive resin layer, and a sealant layer are laminated in this order. In the packaging material, the sealant layer includes a layer formed of a resin composition that contains 60 to 95 mass % propylene-ethylene random copolymer (A), and 5 to 40 mass % polyolefin elastomer (B) including 1-butene as a comonomer and having a melting point of 150 C. or less.

A CNC machining apparatus (14) is configured for machining a rotating part (3;4) of an object (2) by comprising a hinge member (15) adapted to be secured to the object (2) and a CNC X-Y table (16,17,18) securable to the hinge member (15). The CNC X-Y table (16,17,18) comprises a CNC base (16), which is adapted for being rotationally secured to the hinge member (15), a lower linear slide mechanism (17) adapted to be secured in a selected lower working position on top of the CNC base (16), and an upper linear slide mechanism (18) adapted to be secured in a selected upper working position on top of the lower linear slide mechanism (17). The CNC machining apparatus can be used to crown pulley wheels of a band saw while the pulley wheels remain mounted on the band saw. The CNC machining apparatus can also be used on a bench as part of a turning lathe (128).
