Patent CA-2202076-A1 (CA)
Title: Steam condensing apparatus with freeze-protected vent condenser
Inventor: STROCK THOMAS WAYNE
IPC: F28B1/06
Filed: 1997-04-07
Abstract: A two-stage steam condenser that prevents freezing from occurring in the tube rows by continual purging of the tube rows.          Such continual purging prevents any steam from back-flowing into a tube row thereby eliminating the possibility that condensate or noncondensable gases will become trapped therein.  This is achieved by isolating each of the tube rows in the second stage of the condenser so that the pressure of one tube row is not exposed to the pressure occurring in another adjacent tube row.          The condensate collected in the various tube rows of this second stage is delivered to a common drain pot that is hydraulically balanced to accommodate the various pressures in these tube rows.          Such hydraulic balancing also prevents any back-flowing from occurring from one tube row into another.  Furthermore, in this second stage of the steam condenser, the steam and resulting condensate   both   flow  concurrently   downward  while   any noncondensable gases are vented counter-currently upward against such steam and condensate flow.

Abstract: Improved insulating modular panels (200, 210, 220, 240, 260, 270) are manufactured to incorporate into each insulating modular panel (200, 210, 220, 240, 260, 270) at least one vacuum insulation panel (102). Vacuum insulation panels (102) are conveyed seriatim toward a pultrusion die (108) which ultimately produces the insulating modular panels (200, 210, 220, 240, 260, 270) as a continuous block (116). Joint spacings (110, 112, 114) or gaps between adjacent vacuum insulation panels (102) and sides (120) of the vacuum panels (102) are filled with foam or preformed filler material (126, 128) to form a substantially continuous inner core (118) which has substantially continuous side edges. Reinforcement material (136, 150) is applied to the inner core (118). The reinforcement material (136, 150) can be impregnated (140, 152) with resin prior to its application to the inner core (118) or resin may be injected (154) into the pultrusion die (108). In either event, a continuous elongated block (116) of insulating modular panels (200, 210, 220, 240, 260, 270) emerges from the pultrusion die (108). The continuous elongated block (116) is severed at joint spacings (110, 112, 114) or gaps between adjacent vacuum insulation panels (102) to form insulating modular panels (200, 210, 220, 240, 260, 270) of desired sizes from the block (116). Preferably, the sides of the insulating modular panels (210, 220, 240, 260, 270) are formed to define intermating members (212, 222, 242, 262, 272) which engage one another to facilitate construction using the insulating modular panels (200, 210, 220, 240, 260, 270).

Title: Improved system and method for use and storage of geographical data on physical media
Inventor: NYCZAK GREGORY M
IPC: G06F17/30
Filed: 1997-10-24
Abstract: An improved method and system for storage of geographic data on physical storage media. The geographic data are stored in a manner that facilitates and enhances use and access of the data by various navigation application functions in navigation systems that use the data. The geographic data includes a parcelization that separates the geographic data into parcels having less than or equal to a maximum parcel size but having at least a desired fill percentage. The parcelization method also provides for a division arrangement that facilitates addressing and identification of the parcels. According to a further aspect, thegeographic data includes special nodal entities that are used to collapse complex intersections, such as roundabouts, cloverleaves, and divided highways, into simpler data representations. The special nodal entities are associated with road segment data entities and used in a route calculation program in place of regular node entities. Further, the geographic data include a normalized attribute array that includes reoccurring combinations of certain selected attributes of the geographic data. Indices to the array are included in place of data corresponding to the selected attributes. When a navigation application program requests data, an entry in the normalized attribute table pointed to by an index in the data is used to return the requested data in the particular combination of attributes from the normalized attribute array. The geographic data is compiled by a method that facilitates access to the data on a physical medium. According to the compilation method, data files to be stored on the medium are organized into parcels. The data records within the data files are identified by the parcel in which they are located. An arrangement of all the data files on the medium is determined and a parcel identification related to the medium is assigned to each parcel. Cross references between data records areupdated to include the assigned parcel identifications and the parcels are stored on the medium.

Abstract: Une station de base téléphonique permet à plusieurs terminaux cellulaires d'accéder à un réseau de téléphonie à fil dans sa zone locale. Les utilisateurs appartiennent, d'ordinaire, à un groupe spécifique, familial ou d'affaires. La station de base est reliée au réseau de téléphonie à fil par une ligne individuelle de sorte que l'émetteur-récepteur radio de la station de base communique avec les terminaux cellulaires multiples de façon sérielle. Chacun des terminaux cellulaires est authentifié lors de son entrée dans la zone locale. Durant la communication avec un terminal donné, les terminaux restants de la zone locale ne peuvent accéder à la station de base. A réception d'une communication d'arrivée, un message est transmis à l'abonné demandeur pour qu'on puisse identifier le terminal cellulaire souhaité. La station de base communique alors avec le terminal cellulaire identifié et interdit l'accès aux terminaux restants.

IPC: B41J2/455
Filed: 1998-05-20
Abstract: A xerographic light emitter array uses organic light emitting diodes (OLEDs) operating at modest light levels to expose a photoreceptor drum or belt. This isaccomplished by staging a single row array of emitters in the scan direction with increased length of each emitter in the slow scan direction and focusing the increased length and thus increased light level of each emitter onto the photoreceptor in the scan direction. Increased emitter lifetime and the ability to operate at lower light levels are achieved in proportion to the length of the emitter. The focusing lens array can include a divergent cylindrical lens, a Selfoc lens and a convergent cylindrical lens. The emitters can be rectangular in shape to form a square spot on the photoreceptor or the emitters can be elliptical in shape to form a circular spot on the photoreceptor.
