Filed: 1990-01-12
Abstract: A specially constructed block for use in forming a mortarless retaining wall is disclosed, as is a retaining wall constructed therefrom and a method of constructing a retaining wall.  Each block has a front face of a predetermined width and a rear wall having a substantially equal width.  The block side walls provide a maximum block width at the front face and a minimum block width adjacent the rear wall.  When such blocks are placed in a side-by-side relationship, a substantially closed cavity is formed between the blocks for receiving backfill material and thereby reinforcing the wall.  A wall constructed from a plurality of such blocks utilizes an engagement clip disposed between blocks in upper and lower courses for preventing relative forward movement between the blocks.  The clip is engageable with the upper surface of the rear web of the block for easy installation after the block is laid in a course.  The clip engages the inner surface of the rear web of a block in an upper course, and is preferably disposed within the core of the upper block.  Each block is provided with outwardly projecting ears which can be knocked off to form a wall having a radius of outside curvature, and the ears and clips cooperate to allow construction of a wall of inside curvature.

Title: Text search and retrieval system
Inventor: COLWELL STEVE
Filed: 1990-01-17
Abstract: Abstract of the Disclosure A text search and retrieval system which builds an index repesenting every word in stored files created by a variety of applications, searches for requested words using the index and ranks the files based on the relative strength of match with the search request.  From a display of the ranked filenames, the user can select a file, whereupon the file is tested to determine which one of a plurality of file viewers to deploy.  The corresponding viewer is automatically loaded and used to display consecutive screens of information from the selected file.  Further searching within the file is accomplished within the context of the viewer by matching character strings of a new search request with words in the items of the file produced by the viewer.  To work on a file in view, the user can invoke the software application which created the file by loading the application corresponding to the viewer along with the desired file, without abandoning the search system.

Inventor: MONTEITH JOSEPH G
IPC: B01D21/00
Filed: 1990-02-02
Abstract: A separator tank for rainwater and waste-water includes a container defining an upwardly open chamber, with a lid to close the chamber.  An inlet is at a first location and an outlet is at a second location.  A passageway forms part of the container and communicates the inlet with the outlet.  A first opening is adjacent the inlet and communicates the passageway with the chamber, while a second opening is adjacent the outlet, also communicating the passageway with the chamber.  The passageway itself is sealed from communication with the chamber, except for the openings.  A weir is provided within the passageway, disposed with respect to the first opening such that, under relatively low entry flow rates, all entering materials are contained by the weir and flow through the first opening and into the chamber. Under relatively high entry flow rates, the entering materials overflow the weir and are delivered by the passageway to the outlet.

Title: Liquid-crystal display having structured carrier plates and process for producing structured carrier plates
Inventor: RAU LOTHAR
IPC: G02F1/1343
Filed: 1990-07-13
Abstract: Abstract of the disclosure:            Liquid-crystal display having structured carrier plates and process for producing structured carrier plates Liquid-crystal  switching  and  display  devices  have recently found numerous new fields of application such as,  for example,  for flat display screens. A uniform layer thickness of the liquid-crystalline material is of great importance for a satisfactory operation of the LC display.            In order to ensure a uniform layer thickness, spacers are used  in  the  display.  In  the  present  liquid-crystal display, said spacers are composed of projections of at least one of the (glass) carrier plates. These projec-tions have a height of 0.1 µm to 0.1 mm and are obtained by a controlled,  striation-free etching process.  The etching process of the carrier plate(s)  includes  as subordinate steps,  inter alia,  the application of an etch-initiating layer (for example made of titanium), the application of a etch-resisting layer (for example made of  gold)  and  also  the  actual  etching process  (for example, with aqueous hydrofluoric acid).            The displays according to the invention can easily be filled with nematic and smectic LC materials and are mechanically very rigid.

Title: Method and apparatus for pipelined parallel rasterization
Inventor: BIRK YITSHAK
IPC: G06K15/02
Filed: 1990-10-29
Abstract: A rasterizer 10 for converting a datastream 12 which describes a page to be printed into a rasterized pagemap bitstream 13 to be sent to a printer. The rasterization is done in four stages using parallel processors in all stages except the first, and pipelining the processors between all of the stages. In the first stage 11, a scan processor 14 identifies and stores state-independent blocks 14 in the datastream. In the second stage 17, parallel block processors 22 convert the scanned blocks into stored intermediate-form data objects 20 and request preparation of often-used resources such as characters.      In the third stage 23, the objects are sorted and stored by geographical region of the pagemap by parallel sort processors 24. In the fourth stage 31, the sorted objects are rasterized into pelmaps and placed in the pagemap by parallel bin processors 30. All four stages are pipelined. End-of-block markers are used in the third and fourth stages to maintain correct ordering of the objects within the final pagemap. The rasterizer uses general purpose microprocessors for all stages.
