Title: A method and an apparatus for turning boards
Inventor: GUNNARSSON CENNETH
IPC: B65G47/248
Filed: 1997-02-14
Abstract: A method of turning boards (2) comprises the steps that the boards (2) are transported on a conveyor (1) with conveyor dogs (4), with their longitudinal direction transverse to the conveyor (1). The boards (2) are accelerated relative to the conveyor (1) until the front edges (13) of the boards (2) abut against the rear edge (14) of the next dog (4). Lifting devices (16) which move synchronously with the conveyor (1) lift the front edges of the boards (2) at the same time as the boards (2) are moved towards the lifting devices (16), whereby the boards (2) are turned with their front edges facing upwards and backwards.  An apparatus for turning boards comprises a first conveyor (1) with dogs (4) for transport of the boards (2), and a second conveyor (11) with an upper part (12) which, on the first conveyor (1), shunts the boards from one dog (4) to the next. The lifting devices (16) are disposed to move synchronously with the first conveyor (1) and gradually to be raised immediately behind the dogs (4) of the first conveyor.

Title: Indexing databases for efficient relational querying
Inventor: CONSENS MARIANO PAULO
IPC: G06F17/30
Filed: 1998-11-10
Abstract: A computer system for indexing databases for efficient relational querying. A set of index files is created to index an entire set of structured or semi-structured source data. The source data is tokenized. During the tokenization of the source data the source data is manipulated in accordance with the relational data base model. Tokens are generated in the index files to represent the table and the column in the source data for following value tokens. Index files are created to map into the position of data in the source file, and index files which represent the data as sorted lexicographically. The index files include a sort vector file and an associated join bit file. The system provides for efficient relational queries across the entire source data by use of the sort vector file, the join bit file, and related inverted files.

Patent CA-2258604-A1 (CA)
Inventor: PERTHOLD RAINER
IPC: H03F1/32
Filed: 1997-06-17
Abstract: A circuit (10) for predistorting a signal to be transmitted via a non-linear channel (18) comprises an envelope detector (24) for detecting an envelope of the signal (v). A  quantization means (22) for forming quantized envelope values on the basis of the detected envelope is connected to the envelope detector (24) as well as to a table (16) for supplying complex predistortion coefficients which depend on said quantized envelope values and on a previously detected transmission function of the non-linear channel. An evaluation circuit (14) separated from said non-linear channel (18) and used for the complex evaluation of the signal (v) to be transmitted via the non-linear channel (18) with the complex predistortion coefficients permits the distortion introduced by the non-linear channel (18) to be substantially compensated according to amount and phase.

Patent CA-2267820-A1 (CA)
Title: In-line fluid agitator
Inventor: DEERING HARVEY E
IPC: F02M33/08
Filed: 1999-04-01
Abstract: An in-line agitating device for fluids includes an elongate internally-threaded cylindrical tube, open at each end, with a flow-disturber such as a round ball positioned inside the tube so as to substantially but not completely block off the bore of the tube. When a fluid is introduced into one end of the tube, its velocity increases as it is forced through the restricted space between the ball and the inner surface of the tube and then rapidly decelerates, causing turbulence which results in vigorous agitation of the fluid. This agitation is intensified by swirling action imparted to the fluid by the internal threading of the tube.

Title: Network proxy server that alters links
Inventor: CRUICKSHANK III ROBERT F
IPC: G06F17/30
Filed: 1999-04-14
Abstract: A network proxy server that stores frequently requested web pages/sites in a storage area. When a user requests a new web page, the network proxy server gets the new web page from storage local to the server or from remote sources, such as the Internet, and scans the new web page data for any HTML or other links contained within the requested new web page. The network proxy server searches to determine if any of the pages accessible from the links on the new web page are already in local storage. If so, the network proxy server alters the links on the user's screen, either visually, audibly, or both, when the requested new web page is displayed. Thus, the user can visually see and/or hear which web pages are quickly accessible from the requested new web page that are already stored locally on the network proxy server.
