Title: Characterizing matter of biological origin using near infrared spectroscopy
Inventor: CALLIS JAMES B
IPC: G01N21/31
Filed: 1990-09-13
Abstract: A method is provided for predicting a property of a matter of biological origin, such as biological fluid, containing water, where the biological matter may be approximated to contain two compartments where one compartment has a proportionally larger or smaller amount of water than the other compartment having the property of interest. The method involves establishing a training set in the near-infrared (NIR) region with independent quantification of the property of the matter using known techniques. The training set is mathematically analyzed according to a correlation developed by regression analysis after employment of a pre-processing technique.      The result is a mathematical transformation equation which quantitatively relates spectral intensities at specific wavelengths to the property of interest. This transformation equation may be applied to unknown samples so as to predict their properties, thereby eliminating need for the reference method, except for validation and recalibration. The method provides rapid and accurate prediction of the property of the unknown sample, which may be the property of hematocrit or hemoglobin concentration in whole animal blood. The pre-processing technique may be the transformation of the spectra using a multiple derivative calculation, such as computing the second derivative of the several spectra of known and unknown samples.

IPC: H04J3/06
Filed: 1991-02-12
Abstract: An incoming data signal including so-called gaps is synchronized to a new outgoing clock signal by employing a single elastic store and a smooth writeaddress. An elastic store write address is generated in response to an incoming clock signal and is inhibited from advancing during the gaps in the incoming data signal. A smooth clock signal is obtained by appropriately dividing the incoming clock signal by a value dependent on the duration of the gaps in a predetermined portion of the incoming data signal. The smooth clock signal is used to control a counter to generate a smooth write address. The smooth write address is supplied to a phasedetector. An adjusted read address is generated in response to the new outgoing clock signal and is supplied to the elastic store and to the phase detector. A counter used to generate the adjusted read address is inhibited from advancing during intervals in which gaps are to appear in the output data signal from the elastic store. A stuff decision is made at predetermined stuff decision points which are strategically placed relative to the positions of the gaps to be inserted in the outgoing data signal so that apparent jumps in a write-read separate signal generated by phase detector do not affect the stuff decision.

Abstract: APPARATUS FOR CRIMPING TOW INCLUDING               STUFFER BOX, CRIMPING ROTTERS AND                      MOLDING ROLLERS                Abstract of the Invention An apparatus for crimping a continuous tow of textile material including a pair of molding rollers for initial molding and pulling of the tow, a pair of crimping rollers for molding and feeding the two to a stuffer box crimper wherein the tow is crimped.  The novel pair of molding rollers includes the two spaced rotatable rollers cooperating with a side plate at each end of the nip between the rollers to define a rectangular space.          Tow material is passed through the space wherein the tow is pressed and molded to the rectangular configuration.  After the initial molding, the tow is passed through the pair of crimping rollers and fed into the stuffer box wherein the tow is crimped.          Using the novel apparatus to crimp the tow drastically improves the uniformity of the crimped tow and the processibility or the tow.  Furthermore, the novel apparatus allows for a significant reduction in the forces applied to the molding rollers and crimping rollers resulting in the reduction of filament distortion in the tow material.

Title: Toughness and processibility of high heat polycarbonate compositions
Inventor: CHOU CHAI-JING
IPC: C08J3/20
Filed: 1990-10-23
Abstract: (57) Abstract Compositions of polycarbonate having good resistance to thermal deformation, good impact resistance and reduced notch sensitivity are formed from a high heat polycarbonate, an elastomeric toughening agent such as a thermoplastic or core-shell rub-ber, and a flow modifier such as an olefin/carbon monoxide copolymer, a styrenic thermoplastic resin, a polyester or a polya-mide. The presence of the flow modifier in the composition reduces the viscosity of the high heat polycarbonate and thus the tem-perature at which it can be processed or compounded. Compounding at such lower temperature allows formation of the composi-tion at a temperature which is low enough that the toughening agent will not be degraded. The flow modifier should be added to the composition no later than the addition of the toughening agent so that there is an opportunity for the flow modifier to per-form this function.

IPC: C07D409/00
Filed: 1990-02-15
Abstract: A process for the optical resolution of racemic 1,4-dihydropyridines, containing isothioureido groups. Salification of racemic isothioureas with optically active acids produces diasteroisomeric mixtures of isothiouronium salts, that, using conventional techniques, are separated in the individual components to give optically pure isothioureides of 1,4-dihydropyridines and salts thereof with conventional acids. Said optically pure 1,4-dihydropyridines can then be subjected to desulphuration and to different transformations to give other enantiomerically pure and therapeutically useful 1,4-dihydropyridines.

Abstract: An intelligent subsystem separately supports inking functions in order to allow stroke-ignorant software to be  supported  in  a  stylus  driven environment.   This subsystem thus provides the inking capability missing in existing flat-panel display controllers.  Separate inking functions are incorporated into the subsystem in order to support inking management functions which do not corrupt the  display  refresh  buffer  as  it  is  understood  by existing application software.   The subsystem makes no assumptions about the application's awareness of stroke data  as  an  input  modality.   Instead,  the  subsystem assumes that a conventional display subsystem also exists in the system.  The subsystem utilizes the strobes and clocks generated by the conventional display controller to generate addresses in a memory which has physically separate  address  and  strobe  lines  from  the  display refresh buffer.  The content of this added memory is used to control the source of input to the data lines of the display.  The invention can be generalized to allow any number  of  planes  to  be  added  to  a  display  system providing access to that display system by any number of asynchronous processes such as inking.
