Abstract: An apparatus and method for presenting a viewer with an overall representation of the present number of entertainment programs available for selection given one week of program schedule data for 300 or more channels and one or morefiltering criteria to limit the number of items represented in the overall representation. Sequentially applied filters will filter the group of program schedule data items that has at least 100,000 half hour time slots offered by 300 channels each week into a smaller subgroup where individual consideration of each item of the subgroup can be made in a reasonable time. A set top box drives the display of overall representations or results of filtering criteria on a commercial TV set. Once a reasonable sizedsubgroup is obtained, other displays provide specific information of the programofferings of the subgroup. Selection of the filtering criteria and selection from within a subgroup is interactively made by a viewer through the use of a controller that looks and operates very much like a TV remote control. This makes the interaction familiar, easy and predictable.

Title: Improvements in anti-drain back/pressure relieved filter cartridges
Inventor: COVINGTON EDWARD A
IPC: B01D27/06
Filed: 1996-11-12
Granted: 2005-08-23
Abstract: A filter cartridge has an annular filter element retained within a housing by an end plate. The end plate has a central outlet and a plurality of inlet holes. Mounted on the end plate is an annular valve support which supports an annular valve member disposed between the valve support and the filter cartridge. A coil spring urges the annular filter member against the valve member which, in turn, engages the valve support and urges the valve support against the end plate. The valve support has an inner sleeve portion which seats against the end plate and an outer sleeve portion with holes therethrough. The valve member has an expandable collar portion which normally seals the bypass holes and a skirt portion which normally seals the inlet holes. When the filter is filtering lubricating oil for an internal combustion engine, the skirt is deflected by pressurized lubricating oil and flows around and through the filter element before passing out of the central outlet in the end plate.    When the engine is not running, oil in the filter cartridge is blocked from flowing back out of the inlet holes in the mounting plate. If the media of the filter element becomes clogged, then pressure is exerted through the bypass holes in the valve support and applied to the expandable collar of the valve member. The pressure causes the expandable collar of the valve member to expand to uncover the bypass holes. The lubricating oil then flows through the bypass holes and out of the central outlet opening without having to pass through the filter. Preferably, the valve member is made of a low swell silicone material which requires greater pressure to expand at low cold start temperature than at operating temperatures.

Patent CA-2202076-C (CA)
Title: Steam condensing apparatus with freeze-protected vent condenser
Inventor: MILLAS GEORGE STEVE
IPC: F28B9/10
Filed: 1997-04-07
Granted: 2000-06-27
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.

Les lattes faisant ressort sont fixées aux longerons au moyen de barres de support (4) élastiquement déformables situées plus bas que lesdites lattes. Les longerons sont disposés en-dessous des lattes faisant ressort et des barres de support et se trouvent, par rapport aux bords latéraux du sommier, vers l'intérieur, c'est-à-dire près du milieu de celui-ci. Au moins une latte faisant ressort et une barre de support sont reliées, au niveau de leurs extrémités en vis-à-vis (3a, 4a), par un élément de bord (6) à un module de support (7). La barre de support présente une zone centrale (8) élastiquement déformable, située entre les longerons, qui est plus élastique que ses deux zones terminales (9, 10) qui s'étendent depuis les longerons jusqu'aux extrémités des lattes. La barre de support est soutenue par les longerons et fixée à ses points de support par des éléments de retenue (11). La barre de support peut effectuer un mouvement transversal limité par rapport aux longerons correspondants, au niveau de chaque point de support, les sens de déplacement au niveau des points de support étant opposés lorsque le sommier à lattes est soumis à une charge. L'élément de bord présente un moyen de retenue en forme de poche pour chaque extrémité des lattes faisant ressort et de la barre de support. Tous les moyens de retenue sont disposés côte-à-côte le long des longerons et ne se chevauchent pas dans cette direction. Les moyens de retenue sont assemblés par liaison de force, au moyen d'un panneau de couverture formant un pont et conçu comme un élément de support. Les lattes individuelles sont maintenues de façon à pouvoir osciller dans l'élément de bord qui peut lui-même osciller par rapport à la bande de support. Un tel assemblage permet d'obtenir un sommier à lattes garantissant un confort de sommeil au-dessus de la moyenne tout en présentant une esthétique séduisante.

Abstract: Apparatus and method are provided for combining, in real time, weather radar  data in digital format from multiple radar sites into a mosaic covering a regional or national area (e.g., the continental United States). Such apparatus and method is designed to be implementable as computer software an d to run on a general purpose computer such as a personal computer. Such apparatus and method preferably utilizes a database of "lookup tables" which  are used to project individual radar data bins directly to a grid of the desired coordinate system for that mosaic. Using these lookup tables, each o f a plurality of radar data bins is converted to a corresponding grid location  or box in a mosaic image. While each radar data bin is mapped to a grid box for the mosaic, not every such grid box within the coverage area of the rada r may receive such a data bin. Any resulting holes in the produced mosaic are then identified using yet another grid whose locations correspond to those o f the mosaic but which instead provide information regarding the data then appearing in corresponding locations in that mosaic. Each such hole is then filed with data from the locationally closest data bin.
