Title: Marker light for an aircraft landing zone and a color-code angle of descent indicator
Inventor: BRAIN JOHN E
IPC: B64F1/20
Filed: 1990-11-23
Abstract: ABSTRACT      A  marker  light  for  an  aircraft  landing  zone comprising a three-dimensional tapered structure with an inclined light emitting side-wall including an array of electroluminescent   light   strips   generating   visible radiation  with  an  ascending  direction  of  propagation toward a plurality of azimuths.   An electronic control circuit momentarily actuates individual light strips of the array at different instants in time to produce a rapid succession  of  light  pulses  originating  at  different locations  on  the  inclined  side-wall  of  the  tapered structure,  whereby  the  latter  becomes  visible  from different  horizontal  directions.    The  invention  also provides a luminous color-code angle of descent indicator, comprising electroluminescent light sources for projecting chromatically  distinct  visible  radiation  at  different vertical  angles providing  in an  approach area  of the landing zone a light-emission field color-stratified in a vertical direction, whereby establishing for an observer in an aircraft moving toward the  landing zone along a descending path a dependence of the color appearance of the indicator on the aircraft angle of descent.

Abstract: In the representative embodiments of the invention described in the specification, an ink jet head has a series of aligned arrays of ink jet orifices arranged to project drops of different colored inks in sequence to the same location on a substrate during each scan of the ink jet head adjacent to the substrate. The spacing of the orifices in each aligned array and the speed of the ink jet head during the scanning are arranged so that all the ink drops applied at the same location on the substrate are applied in a time period of no more than about 100 milliseconds and preferably no more than 50 milliseconds. Moreover, to avoid banding the lines produced by successive scans of the head are interlaced so as to produce a periodic frequency of no more than about four lines per millimeter.

Abstract: DISPOSITIF DE SUSPENSION POUR BASE ACOUSTIQUE L'invention concerne les dispositifs de suspension des bases acoustiques de sonar (2) à l'intérieur de leur dôme de protection (9). Elle consiste à utiliser deux biellettes (3, 4) articulées d'un côté sur la coque du bâteau (5, 6) et de l'autre (7, 8) sur la base, acoustique. Ces biellettes forment une triangulation qui impose lors des mouvements de la base une rotation de celle-ci autour d'un centre instatané de rotation (R) situé au-dessus du centre de gravité (G) de la base. De cette manière lorsque la base vient toucher la surface intérieure du dôme, le choc se produit surface contre surface et non pas coin contre surface, ce qui limite les dégâts dus aux chocs. Elle permet d'obtenir simultanément une suspension très libre de la base acoustique et une bonne protection du dôme sonar. FIG. 1

Abstract: Les boitiers d'alimentation A.C. utilisés en cablodistribution contiennent des batteries et un bloc d'alimentation. Dans la plupart des cas, lorsque l'on doit remplacer ces composantes, on se sert d'un palan qu'on accroche au toron d'acier situé au-dessus du boitier d'alimentation. Dans les cas où il n'y a pas de toron d'acier ou lorsqu'il est inutilisable, le support de levage portatif (invention) permet d'accrocher le palan au-dessus du boitier d'alimentation A.C. et permet aussi de déplacer le palan latéralement. Le support de levage portatif s'adapte sur le dessus du boitier d'alimentation A.C. et s'y fixe par gravité. Un panier adapté au support de levage permet d'y déposer les batteries ou le bloc d'alimentation A.C. Le support de levage est pliable pour faciliter le rangement. Le crochet du support de levage est placé sur une glissière pour déplacer latéralement le palan. Une barrure de sûreté empêche le support de se replier lorsqu'on l'utilise.

Inventor: OKANO HIDENOBU
IPC: B29C44/58
Filed: 1991-06-10
Abstract: Disclosed herein is a method and apparatus for producing a molded polyurethane foam without using low-boiling solvents such as Freon and methylene chloride which present problems when used as a blowing agent. The polyurethane foam has the same good appearance and soft feeling as that produced with low-boiling solvents.      A polyurethane foam is produced by injecting a polyurethane material into an evacuated cavity and permitting it to expand so that it flows and fills the cavity, said polyurethane material being composed of 100 parts by weight of polyol component and 0.1-0.6 part by weight of water as a blowing agent. The cavity pressure may be maintained high spontaneously or low while the polyurethane material is flowing in the cavity. When the polyurethane material has reached the final fill position in the cavity, the fore-end of the polyurethane material is discharged from the cavity.

Title: Air cooled heat exchanger for multi-chip assemblies
Inventor: BERENHOLZ JACK
IPC: H01L23/427
Filed: 1991-06-28
Abstract: ABSTRACT OF THE DISCLOSURE      In an air-cooled self-contained evaporator and condenser apparatus with no external power source  for cooling a multichip unit,the apparatus includes a cold plate having a first surface with recesses formed therein (which recesses might have aluminum nitride slugs for heat transfer) in a matrix or array corresponding to the matrix or array of chips on a multi-chip module or unit.  The opposite surface of the cold plate includes a finned arrangement which, in conjunction with the cold plate, forms part of an isolated evaporation chamber of the cooling unit with the chamber housing a boilable fluid which changes phase from liquid to vapor.  Positioned above and contiguous with the isolated chamber is a condensing chamber, including a plurality of finned tubular passageways.  Heat is transferred from the chips through the slugs, through the cold plate to cause boiling of the fluid within the chamber, the vapors of which are condensed in the upper part of the cooling unit to thus return as fluid to the chamber.

IPC: G06T11/20

Abstract: An integrated hardware generator (12) for generating digital signals representa-tive of vectors, polygons and conics primitives and area fills therefor. The primitive signals are used in the formation of a final digital output signal read into a bit map memory  (22) of a graphics display processor. Its operation is based on applying one or more of a set of internal subfunctions to generate mathematical solutions for render-ing each geometric shape as a graphics primitive digital signal. The basic building block of the generator (12) is a digital differential analyzer (60) which is adapted to ac-cumulate fractional (subpixel) components of x/y coordinate data and to signal when the accumulation overflows across pixel boundaries. This occurrence enables an in-crement or decrement of the x/y coordinates that indicate the pixel address to be loaded (drawn). The digital differential analyzer (60) forms an independent vector generator and comprises a pair of input differential comparators (62) an arithmetic logic unit (64) and register and counter files (66 and 67). On receipt of a command from a host processor (14) the comparators receive updated x and y data, compares them to the present values which are stored in the register file (66) and forwards the differences to the arithmetic logic unit (64). When either the x or y value exceeds the pixel boundary, the arithmetic logic unit (64) computes the coordinates of the next pixel to be filled and inserts them into the register file (66) to replace the previous values.

Abstract: In a policing arrangement for an ATM network, every incoming cell is stored in a cell buffer and a virtual path identifier (VPI) contained in the cell is extracted and translated to a corresponding one of a set of threshold values.  Policing circuits of a matrix array are connected column by column for transferring a VPI in accordance with a read/write control circuit.  Each policing circuit of the first column is uniquely responsive to a VPI of a particular value for storing the extracted VPI into a bridge memory, and this column has a greater number of policing circuits than any of the other columns of the array.  At least one of the policing circuits of each row of the array includes a cell counter for incrementing a cell count value in response to the VPI of every incoming cell and decrementing the cell count in response to a VPI of the bridge memory of the policing circuit.  The cell count value is compared with the threshold value and a cell is discarded from the cell buffer when the cell count value exceeds the threshold value.
