Abstract: ABSTRACT OF THE DISCLOSURE     A controlled clutch/brake unit having a control interface between a computer and a clutch/brake unit to learn what position exists in a particular application, to learn what movement has to be done to attain a targetted stopping position, to make corrections within the control system by the control system itself until the desired targetted stopping position has been accurately attained, and to keep correcting as the work operation progresses in order to automatically compensate for any error in the system as it drifts off due to temperature or any other factor. An index table application is also described having any number of stations, which number of stations may be readily altered by mere removal and repositioning of target buttons without change in the computer program, and having a pneumatically controlled, oil cooled clutch/brake unit integrally disposed within the control system of the index table.

Abstract: Abstract Methods  and  media  for  preparing  bulk  cultures  of exclusively proteinase negative lactic bacteria and methods for making fermented dairy products such as cheese, cottage cheese,  and  sour  cream  employing  exclusively  proteinase negative lactic bacteria.  In one preferred embodiment, the medium   comprises   a   whey-based,   pH-controlled   medium containing  sufficient  nitrogenous  nutrients  to  render the medium  suitable  for  growing  proteinase  negative  lactic bacteria.  The medium is heated to inactivate bacteriophage present  therein and  subsequently  cooled  to  a  temperature favorable  to  the  growth  of  proteinase  negative  lactic bacteria,  and the proteinase negative  lactic bacteria are introduced  into  the medium and allowed to propagate to a population sufficient to serve as an inoculant in making the particular fermented dairy product.  The proteinase negative lactic  bacteria  culture  and  an  appropriate  enzyme  are introduced into a vessel containing a quantity of milk where coagulation and syneresis of the milk occurs to produce the fermented dairy product.

Out-puts from the contacts are applied to a digital-to-analog converter which converts the digital contact switching in-formation into an analog signal related to a dimming level for the gas discharge lamp circuit.  The analog output sig-nal is connected through a fader circuit to the proportional control electrode of the gas discharge lamp dimmer system.

Abstract: ABSTRACT OF THE DISCLOSURE           The disclosed methods improve conventional agglu-tination processes for assaying immunoreactive and like substances, primarily by improving the measurement of the agglutination itself.  Suspensions containing agglutinated particles are automatically inspected, preferably intermit-tently during the agglutinating reaction, and the resulting data are processed to identify individual particle aggrega-tes of a selected limited class, which may, for example, comprise aggregates having sizes within a limited size interval.  The numbers of such aggregates are compared with corresponding reference values obtained with standard solu-tions and suitable controls to evaluate the concentration of one of the reactive substances, or other information.          The aggregate size intervals and other parameters which are used to define aggregate classes are preferably selected with attention to the detailed behavior of each test system.

For calibration, a second aspirator is provided in the input line for equalizing the flow in the input and the output lines to stop the flow of sample gas through the analyzer.  After the flow is equalized and thus reduced to zero, a test gas is supplied to the input line at the same selected flow rate as the sample gas was supplied through the analyzer.  The test gas is used for calibrating the analyzer.

Abstract: ABSTRACT Polarized shear wave surveys are performed to determine azimuthal variations in the earth's subsurface caused by fracture orientation and density.  The surveys may be done by using the same polarization (either horizontal or ver-tical) shear waves along two different seismic lines of profile, or by using different polarization shear waves along one common line of profile.  The survey data are then processed and compared; any differences constitute a measure of fracture orientation and density.  Subsurface zones of high fracture density, once identified, have been found to afford a higher likelihood of successful well completion.     TDS: jde/mh
