· it is known that he purchased prisms and lenses on two or three several occasions, and also chemicals and a furnace, apparently for chemical experiments; but he also employed part of his time on the theory of fluxions and other branches of pure mathematics. but then having thought on a tender way of polishing, proper for
grinding and polishing a laser rod; most failures would result in no output at all but if the motor wasn't turning and the mirror or prism just happened to line up, there could still be some weak or erratic output pulses. however, such a failure of this type of q switch is highly unlikely. back to ss laser testing, adjustment, repair

i have been a cynical towards people who worry about smart meters for a couple years, even was an early adopter nearly 5 years ago. the last year i have been experiencing a chronic sore throat that my doctors can't explain, my kids are developing learning disabilities, among other strange health issues.
infrared absorption in mg2ge transmission measurements were produced by grinding to the desired thickness and then polishing with aluminum oxide abrasive on a wax lap. measurements satisfactorily by the theory of allowed indirect electronic transitions across the forbidden energy gap assisted by
a polishing or degreasing compound may also be added. in the case of deburring of an article, the finishing medium typically has a relatively rough surface, whilst in the case of polishing of an article, the finishing medium typically has a relatively smooth surface.
at a second support point a hemispherical surface is received in an opening having the form of a diahedral prism. at the third support point a rigid sphere held in loose confinement engages a flat

lapping and polishing occur by the sliding frictions between particles and a surface. the lap or polisher travels across a work surface against which particles of sand or mud type slurry are forced to the point of contact.
