Method and plant for manufacturing braking elements such as vehicle brake pads. The plant can comprise a first station that applies an adhesive to a first face of a metallic element; a second station that applies to the first face of the metallic element a block of friction material; a checking station that verifies the presence of the adhesive by detecting the gray level of a plurality of points of at least one zone of the first face; and a processing unit that compares the gray level detected for each point with a first threshold value, counts the number of points that have a gray level that satisfies a relationship (which is a function of the threshold value,) and compares such a value with a second threshold value to discard those metallic elements for which the percentage calculated does not correspond to the second threshold value.

The inflatable bag may be arranged to provide air to a patient through a face mask or an endotracheal tube in response to compression/retraction actions applied to the inflatable bag. The respirator body may include a first cover portion and a second cover portion arranged to enclose moving components of the portable respirator and define a substantially circular opening for the inflatable bag to be fitted through, a motor, a pair of levers positioned on opposing sides of the substantially circular opening, and a cam mechanically coupled to the motor and arranged to move the pair of levers in response to a rotation action by the motor such that the pair of levers apply the compression/retraction actions to the inflatable bag fitted through the opening.
Technologies are described for a durable high friction coating (DHFC), which may be manufactured by mixing a binder, a filler, and one or more additives in liquid form, loading the liquid mixture onto a coil material (metal substrate) and curing for subsequent cutting and/or stamping. The metal substrate with cured DHFC layer(s) may be cut to shape to form brake shims. Water-based binders may be used for environmentally friendly chemicals. In some examples, the binder(s) in the DHFC may be in a range from at least 70 weight% to less than 95 weight% and the filler(s) in a range from at least 5 weight% to less than 30 weight% with an elastomeric polymer in a range from at least 1 weight% to less than 8 weight% and a rheology modifier in a range from at least 0.5 weight% to less than 2 weight%.
