Title: Process and apparatus for modifying polyamide amine end content
Inventor: PARLEE BRIAN R
IPC: C08G69/48
Filed: 1989-11-01
Abstract: ABSTRACT             PROCESS AND APPARATUS FOR MODIFYING POLYAMIDE AMINE END CONTENT      A process for controlling the amine end content or dyeability of polyamide articles during the manufacture thereof is disclosed. The articles are manufactured by forming them from a stream of molten polyamide.  Firstly, either a dyeability measurement or an amine end measurement of the articles is taken at periodic intervals.  The dyeability measurement or amine end measurement is then compared to a set point representing the desired dyeability or number of polyamine ends of the articles.  Diamine is then injected into the stream of molten polyamide in response to any deviation of the dyeability measurement or amine end measurement from the set point. The diamine is injected at an injection rate determined by the equation:     Injection rate = current injection rate + (correction factor) x (dyeability change or amine end change) x (polymer throughput).     The correction factor is determined empirically.  The polyamide and the diamine are then combine to provide a polyamide having a modified amine end content.

Patent CA-2010738-A1 (CA)
Inventor: GESSAMAN BILL
IPC: H03K7/06
Filed: 1990-02-22
Abstract: ABSTRACT OF DISCLOSURE      A circuit arrangement reduces the time necessary for a voltage-to-frequency converter to provide a new output  frequency  in  response  to  a  change  in  input voltage levels.   A current source provides additional input current to the input integrating node of the v/f before a conversion is requested.  When a conversion is requested,  the  additional  input  current  effectively provides  operation  of  the  v/f  at  an  increased frequency, thus speeding the settling process therefor. When the integrator of the v/f is at a predetermined voltage level in a predetermined operating cycle, the current  source  is  removed,  thus  terminating  the increased frequency of operation.

Title: Method and apparatus for determining the arterial blood pressure in non-invasive manner
Inventor: MEISTER JEAN-JACQUES
IPC: A61B5/022
Filed: 1990-03-07
Abstract: METHOD AND APPARATUS FOR DETERMINING THE ARTERIAL BLOOD            PRESSURE IN A NON-INVASIVE MANNER            ABSTRACT OF THE DISCLOSURE     This  method  for  establishing  blood  pressure  in an  artery  employs  the  measurement  results  from   two non-invasive  sensors  (5,  6)  of  artery  diameter   at  two closely  spaced  locations  (3,  4)  separated by a distance .DELTA.x.  The  method  provides  for  measuring  the  time  spread .DELTA.t(7) between each pair of diameter measurements and establ-ishing the propagation velocity of the pressure wave (9). Next,  this value is compared with an expression  (11)  of the  form  c(D)= c(D,.alpha., .beta., .gamma.,...)  which takes  into account the physical behaviour of the artery. This comparison per-mits one, following  adjustment (12) based on a mathematical procedure for minimizing spreads, to calculate the parame-ters .alpha., .beta., .gamma.,...  of  the  relation  given  hereinabove.  By replacing the parameters .alpha.,.beta., .gamma.,...  by their values in a relation  (10)  D(p)= D(p, .alpha.,.beta., .gamma.,...)  and in employing the measurement results from a diameter sensor, one may deduce the blood pressure value p(t) at each instant of the cardiac cycle. The blood pressure value together with the corres-ponding value of the artery diameter permit tracing a pres-sure-diameter curve (14) by means of which the mechanical properties of the artery may be measured.

Title: Method for enhancing the uniformity and consistency of dot formation produced by color ink jet printing
Inventor: TRASK JEFFREY L
IPC: G06K15/10
Filed: 1990-06-19
Abstract: A multiple pass complementary dot pattern ink jet printing process for enhancing the uniformity and consistency of dot (drop) formation during color ink jet printing.  Such enhancement in turn directly affects and improves the total print quality over a color printed area by minimizing the undesirable  characteristics  of  coalescence,  beading,  hue shift, banding, cockeling and color bleed when printing on both transparencies and plain or special papers. Using this process,  successive printed swaths are made by depositing first and  second partially overlapping complementary dot patterns on a print media.  Simultaneously, the dot spacing in coincident dot rows within the overlapping portions of the dot patterns is alternated between dots in the first pattern and dots in the second pattern.  This invention is also directed to the novel process of combining complementary pass ink jet printing as described above with dot-next-to-dot (DND) super pixeling in order to further optimize the ink drop drying conditions  desirable  for  producing  the  above  optimized uniformity and consistency of dot formation over a given color printed area.

Title: Optical recording medium and method for recording and reproducing information therein
Inventor: SAKO YOICHIRO
IPC: G11B7/004
Filed: 1990-08-24
Abstract: An optical recording medium for storing optically readable data includes at least one preformed recording track of predetermined width and extending in a predetermined recording direction, the recording track having a recordable region extending in the recording direction thereof for recording data containing clock signal components, the recording track being provided with predetermined offset portions extending in the direction of the width thereof representing offset recorded data, the offset portions being formed such that the offset recorded data has a frequency upon scanning the recording track related by an integral ratio with respect to the clock signal components of the data.  When principal information signals are recorded on the track of the recording medium, clock signals are produced with the use of the offset recorded data and, when the principal information signals are reproduced from the recording medium, the offset recorded data are used for accessing, so that record and reproduce clocking may be produced from signals wholly apart from the principal information signals recorded in the recording track.  In addition, by providing offset portions of the recording tracks, it is possible to record information outside of the recordable region of the recording track.  In one embodiment, the phases of clock components of the principal information signals are recorded therewith so that when these signals are reproduced, a phase locked loop produces reproduced clocking signals having a frequency based upon the offset data signals and a phase determined by the signals recorded in the recordable region.  This serves to reduce the time required for frequency and phase capturing and eliminates the need to provide a lengthy clock capturing preamble region in the recording track.

Title: Moving floor type slef-unloading truck body and power drive mechanism
Inventor: COOK PETER P
IPC: B60P1/00
Filed: 1990-09-19
Abstract: ABSTRACT A self-unloading load hauling box for use on a towed carriage or carried by a powered mobile vehicle wherein the box is a rigid unit having a bottom wall with a floor plate and side walls and front end wall projecting up from the rigid bottom wall.  An endless belt is looped around the bottom wall and runs on a driven roller at the rear end of the box and an idler roller at the front end of the box.  The endless belt is driven intermittently through an arc of selected length at spaced apart intervals of selected duration to unload contents from the box.  The jerky action from intermittently driving the belt has a tendency to cause a vibration, loosening the content in the box and thus results in a relatively even discharge during unloading.  Between the upper run of the endless belt and the upper surface of the floor is a friction reducing pad which also absorbs shock loads tending to reduce damage to the belt and/or floor when loading heavy chunk material. The box has a tail gate mounted in such a manner that during an initial period of opening the tail gate, it restricts discharge of contents from the box and thereafter during further opening pivots freely providing an unrestricted discharge opening.
