| A vibration isolating apparatus comprises an upper bed which is placed with an object thereon, a lower bed which directly receives a vibration caused by an earthquake, a support mechanism for supporting the upper bed so that the upper bed is relatively displaceable with respect to the lower bed in a horizontal direction with a small friction, a plurality of guide members separated from each other and provided on the upper and lower beds, a wire member provided around the guide members in a form of a loop, and a spring mechanism for absorbing a tension in the wire member depending on a deformation of a shape of the loop formed by the wire member due to a displacement of the lower bed with respect to the upper bed caused by the earthquake. | ||||||
| 262 | Method and apparatus for stabilizing high-dynamics devices | US6001 | 1987-01-21 | US4924749A | 1990-05-15 | Otto Beyer; Bertold Kirst |
| A method and apparatus for stabilizing relatively high-dynamics devices (e.g. a sight) mounted on a low-dynamics support such as a tank. Movement of the low-dynamics support is determined by means of an inertial central sensor block that may comprise a strapdown set of gyros or gyros and accelerometers. Stabilization is achieved by a two-step process in which the individual high-dynamics devices are stabilized with respect to the support by means of large bandwidth control loops. The much slower support movement is applied to a superposed loop of appropriately smaller band-width. Compensation thereby takes place by specifying a reference value for the control loops of the higher-dynamics devices. | ||||||
| 263 | Apparatus and process for measuring an optical characteristic of a predetermined portion of a flat object | US806784 | 1985-12-09 | US4900148A | 1990-02-13 | Stephen Doerr |
| An apparatus for measuring an optical characteristic, such as color, of an object having two edges comprises a support for the object, a stop member slideable but releasably secureable to the support in a variety of different positions allowing for variation of the position of the stop member in two dimensions, and an optical instrument for measuring the desired optical characteristic. In use, the two edges of the object to be tested are abutted against two stop surfaces on the stop member and the optical instrument lowered adjacent the object to determine the optical characteristic of a portion of the object beneath the instrument. A number of similar objects can be tested by abutting them in turn against the stop surfaces of the stop member. | ||||||

A clamping assembly with an elastomer isolation pad holds the carriage onto three upward protrusions over each support assembly. A clamping assembly with an elastomer isolation pad holds the carriage onto three upward protrusions over each support assembly. | ||||||
