  • Design of a grating mechanism for a near-infrared spectrograph
    Through this exercise we chose 17-4PH stainless steel for the cam and a proprietary alloy called AMPCO-M4 for the follower, given a maximum force at the point of contact of 100 lbs. from the two preloaded springs'5. .... The housing is balanced by a counterweight so that the pressure between the cam and the follower is limited to that from the springs, and eliminates the varying gravity components as the telescope tracks.
  • Practical to tactical: an evolution of the dual line-of-sight experiment
    The axis drives are each made of 440C stainless steel to match the thermal properties of the bearings and allow the bearings to operate predictably over a wide temperature range. .... The elbow assembly includes the elevation drive, the azimuth FOG sensor, the elevation fold optic, and the counterweight for the telescope mass.
  • Research on the support structure of the primary mirror of large-aperture telescope
    The A frames are stainless steel complex devices linked to the mirror by means of Invar pads glued on the outer ribs. .... The lateral support frame includes a counterweight system to minimize deformation of the mirror surface dues to … pull counterweighted levers, springs, and pneumatic/hydraulic actuators are all commonly used in astronomical telescopes , as well as…

    During transportation, shock absorbers (made of stainless steel encased in balsa wood collars) are fixed to the ends. .... telescoping mast. .... counterweight .
  • Design of the primary mirror segment support system for the E-ELT
    Keck used the approach of counterweights glued to the segments, and TMT (Thirty Meter Telescope )[2] has proposed the machining of the pivot position of the whiffletree at slightly different positions for each segment type. .... The material of the tripods is an Al-Si alloy, the material of the pivots is a martensitic stainless steel and material of the end needles is a precipitation hardened high strength stainless steel.
  • System description and first light-curves of HAT, an autonomous observatory for variability search
    The right ascension is driven by a five-phase stepper motor via sprockets and cog- wheels and a stainless - steel roller with combined gear-ratio of 1 microstep of the motor = 1′′ (arc- sec) movement of the horseshoe. ....
