Abstract: ABSTRACT OF THE DISCLOSURE         Apparatus for conducting fluorescent spectroscopy with sensitivity levels sufficient for precise fluorescence immunoassay measurement on extremely dilute solutions.  An improved filter assembly rotatable between a test position and a reference position.   The filter assembly includes a pair of test filters, one passing excitation light at one wavelength and the other passing fluorescent light from a test solution at a second wavelength, a pair of reference filters, each passing light at the first wavelength, and light shielding means to block stray light and prevent it from optically coupling between the filters.  A pre-filter minimizes the background transmitted light.  Insertion of the filter assembly into a commercially available automated clinical photometer enables the instrument to be used as a filter fluorimeter.  The disclosure also describes a method for conducting fluorescent spectroscopy which involves irradiating a test sample with light of a first wavelength which causes the test sample to fluoresce light of a second wavelength and measuring a portion of the fluorescent light; irradiating the test sample with light of the first wavelenght at reduced intensity and measuring the light of the first wavelength transmitted through the test sample; and comparing the intensity of the fluorescent light to the transmitted light.  The invention also includes apparatus for carrying out the above method.  The methods and apparatus of this ivention are particularly useful in clinical chemistry.

Abstract: ABSTRACT         An expansion dowel assembly includes an axially elongated sleeve having a leading end and a trailing end, a spreading member located within the sleeve adjacent its leading end, and a threaded bolt extending into the trailing end and toward the leading end of the sleeve.  The threaded bolt is axially movable through the sleeve between a first position where the dowel assembly can be inserted into the bore hole and a second position where the bolt is driven further through the sleeve into the spreading member thus radially spreading both the spreading member and the sleeve and the threading on this bolt enabling the bolt to be screwed into the spreading member, after driving in.  An abutment is provided at the leading end of the sleeve to prevent displacement of the spreading member out of the sleeve when the bolt is driven from the first position toward the second position, and a flange is provided at the trailing end of the sleeve to limit entry into the borehole.  A flange is located on the trailing end of the sleeve, and it is displaceably retained in position so that it can be deflected radially inwardly.

Abstract: FAULT-TOLERANT COMPUTER SYSTEM     ABSTRACT A fault-tolerant computer system provides information transfers between the units of a computing module, including a processor unit and a memory unit and one or more peripheral control units, on a bus structure common to all the units.  Information-handling parts of the system, both in the bus structure and in each unit, can have a duplicate partner.  Error detectors check the operation of the bus structure and of each system unit to provide information transfers only on fault-free bus conductors and between fault-free units.  The computer system can operate in this manner essentially without interruption in the event of faults by using only fault-free conductors and functional units.           Arbitration circuits of unusual speed and simplicity provide units of the computing module with access to the common bus structure according to the priority of each unit.           The units of a module check incoming and outgoing signals for errors, signal other module units of a detected error, and disable the unit from sending potentially erroneous information onto the bus structure.

Abstract: Recoil System With Guided Slide Assembly for Track-Type Vehicles Abstract A track-type vehicle includes a track roller frame, a track idler mounted forwardly on the track roller frame, and a recoil system interconnected between the track roller frame and the track idler . Conventional recoil systems, such as those employing one or more return springs therein, are sometimes sub-jected to adverse impact loads which could unduly subject undercarriage components to high stresses. This invention is directed to a slider assembly slidably mounted for fore and aft movements on the track roller frame and having the track idler rotatably mounted thereon.  Linear movement of the slider assembly on the track roller frame is guided by a pair of guides laterally spaced on either side of the track idler.
