Title: Electronic printing method
Inventor: PLUMMER WILLIAM T
IPC: G03B27/72
Filed: 1987-04-14
Granted: 1991-09-24
Abstract: ABSTRACT OF THE DISCLOSURE         An electronic printing method by which originals are photographically reproduced by exposing high-contrast copy material with an intensity modulated illumination source that coarsely scans the original while the original is sharply imaged with a well-cor-rected optical system.  The source intensity is modulated to compensate for the original's tonal qualities and electronically shapes the response of the copy material to enhance tonal reproduction.  The imaging system in conjunction with the high-contrast material assures high reproduction of detail.  The method enhances copy sharp-ness and reduces copy time, memory and computational needs otherwise required for copies of comparable quality.

Title: Vibration-absorber
Inventor: SCHIEL CHRISTIAN
IPC: F16C/
Filed: 1987-10-28
Granted: 1992-06-09
Abstract: ABSTRACT    A  roll  with  a  roll-shell  rotating  about  a stationary central axis.  A first chamber located in the interior  of  the  roll  is  filled  with  fluid  which transfers a hydraulic supporting force from the central axis to the roll-shell.   The said first chamber is connected, through at least one choke-point, to a second chamber also located in the interior of the roll which is at all times only partly filled with fluid.  Thus, in the event of a change in pressure in the first chamber, the volume of liquid in the second chamber can change quickly.    When  therefore  the  roll-shell  tends  to vibrate, fluid flows back and forth through the choke point and, as a result of fluid-friction, vibrational energy is converted into frictional heat.

Abstract: A method for purifying hemoglobin, mixed with other proteins is described, wherein the mixture is contacted with an ion exchange matrix so that the hemoglobin is adsorbed to it.  The matrix is washed to remove unadsorbed components, and the hemoglobin is then selectively eluted using a ligand which specifically binds the hemoglobin causing it to desorb from the matrix.  The method can also be used to effect reduction of methemoglobin to hemoglobin on an ion exchange matrix followed by selective elution to achieve purification.   The method can also be used to purify methemoglobin.

Title: Fiber optic sensor
Inventor: POORMAN THOMAS J
IPC: G01H9/00
Filed: 1988-08-24
Granted: 1992-10-27
Abstract: ABSTRACT OF THE DISCLOSURE     The invention is an optical fiber sensor system in which an optical source,  such as a laser diode, emits a pulse of optical energy which is transmitted in an optical path  through  an  optical  energy  modulator.    A  partial reflector, included in the optical path before the optical modulator, reflects a portion of the optical energy of the pulse.    The  optical  path  terminates  in  an  optical reflector, where the pulse is reflected back through the optical modulator to the partial reflector. The optical energy  reflected  by  the  partial  reflector  and  the terminating reflector travels along the same optical path from  the  partial  reflector  to  a  photodetector  and demodulator,   where  the  magnitude  of  the  parameter modulating  the  light modulator  is  determined  from  the relative  magnitude  of  the  energy  reflected  from  the partial reflector and the terminating reflector.
