Title: Laser nephelometric system
Inventor: TSUJI YASUHIRO
IPC: G01N21/47
Filed: 1981-07-30
Granted: 1986-05-28
Abstract: A laser nephelometric system measures the concentration of various substances in a solution particularly in blood or serum. The system receives a number of data elements each indicative of the intensity of light scattered from the solution at its sampling time. These data elements are processed in accordance with a statistical analysis. Based upon the fact that the relative variation of the scattered light intensity increases as the scattered light decreases, a first screening of data elements is performed so that the band of selection for data elements accords with the above fact. Further a second screening of data elements is performed in order to reduce the effect of the unnecessary light resulting from the other reflecting objects, such as dust, air bubbles and other substances. The average of the screened data elements provides an accurate value of the intensity of scattered light due to the substances to be measured, i.e. measurand.

Title: Vibration damping arrangement
Inventor: VENUTI GUY S
IPC: H01J37/02

Granted: 1987-10-15
Abstract: A cryogenic vacuum pump has an expander module (12) suspended from the vacuum chamber of an electron microscope by a metal bellows (32) which dampens the vibrations transmitted to the electron microscope from the expander module. A weight (44) mounted on the expander module and disposed around the bellows counters the lifting force of the atmospheric pressure acting on the expander module and protects the bellows. The expander module is maintained in a centered position by vibration damping isolators (50) disposed symtrically around the expander module and which are attached to a support (10) extending down from the vacuum housing. In one embodiment the isolators are bar magnets which repel magnetic ring attached to the expander module. In another embodiment the isolators are ladders in which the rungs are wire cables tensioned between a side members attached respectively to the expander module and to the support. The compressor (16) of the cryogenic vacuum pump is a separate unit having a high pressure feed line (14) and a low pressure return line (16) which are connected to the inlet and outlet of the expander module by helical flexible hoses having freely suspended turns which damp the vibrations transmitted by the hoses.

Date May 24, 1984.A single mode optical fiber switch having a base (70) and a laterally slidable top (91). The base is composed of a quartz block (70) with a slight radius of curvature along its length supporting a silicon substrate (66) having a plurality of parallel v-grooves (68). The grooves are fitted with single mode optical fiber segments (64) and lapped to create a flat coupling surface (82) extending laterally across the base. The top (91) is composed of a quartz block with a single v-groove (93) holding a segment of single-mode fiber (95). This fiber (95) is lapped to create a flat coupling surface matable with the coupling surface on the base. The base (70) and top (91) are placed together such that the top fiber (95) may be selectively slid into and out of coupling alignment with any of the fibers (64) in the base (70) to form a discretely variable delay line. A single length of fiber (121) is wrapped around the base ( 70) in helical fashion with each loop being secured in one of the v-grooves (68). By coupling the top fiber (95) with different loops of the base fibers (121), different amounts of delay can be obtained. The delay line can be used to provide variable frequency response for notch and transversal filters.
