Abstract: Disclosed is a hose strangler which considerably reduces the risk of slippage when the strangler is being removed from the hose. The hose strangler includes a clamping member adapted to hold a hose in position. The clamping member has a first arm having a concave portion for receiving the hose and a second arm having a convex portion matching the concave portion of the first arm, the concave and convex portions defining a hose strangling area, where the first and second arms are pivotally secured at a first end so as to permit the clamping member to rotate between a closed position and an opened position. A blocking mechanism to open and close an opening between the first and second arms is also provided, where the blocking mechanism is located in the hose strangling area. A locking mechanism is also provided for securing the clamping member in a closed position. In use, when after the hose has been strangled and the necessary work done, the opening between the first and second arms is open so as to equalize the pressure on both sides of the hose. Once the pressure has been equalized, the locking mechanism can be unlocked and the hose strangler removed safely and without causing any injury.

Title: Pre-paid phone card
Inventor: SCRYMGEOUR LYLE HAROLD
IPC: G06K19/18
Filed: 2001-09-24
Granted: 2002-09-17
Abstract: Described herein is a pre-paid phone card composed of two card portions, each having a rear surface and a front surface. The front surfaces include promotional graphics and phone card information including a value of service to be provided in relation to the card. One of the rear surfaces includes a PIN, which may be covered with a scratch-off layer. The card is formed by connecting the rear surfaces together around an edge with one of the portions including a surrounding line of weakness allowing separation of that portion from the remaining card part.   The PIN is thus facing inwardly and not visible without separating the card into its two portions. The card thus forms in effect a pouch enveloping the PIN and keeping it more secure but without the wastefulness of additional wrapping material.  If the part without the PIN includes on its rear surface material of value to the user, this encourages the user to keep both parts for recycling.

Title: Data parsing system for use in electronic commerce
Inventor: CLARKE WILLIAM D
IPC: G06Q30/00
Filed: 2000-02-11
Granted: 2006-09-12
Abstract: A parsing technique suitable for use in electronic commerce that avoids the disadvantages of known monolithic parsers. The parsing system generates code specific to each input document and data stream type, which may then be updated as needed to handle document-specific idiosyncrasies without requiring modifications to the core parser code. As a user (10) defines parsing rules for extracting data from a representative sample document (15), a visual trainer (16) automatically generates code in the background, referred to as a filer (17), that is specific to that document and that embodies the rules for extracting data from that particular document. The generated code may be modified manually (18) as needed to account for any idiosyncratic conditions associated with the document. Each representative document has associated with it its own filer. A parsing engine (20, 21) comprises a collection of such individual filers appropriate for the types of documents that arise in any given organization. A mapping or other association is maintained between representative document types and their filers. In regular operation, a user selects a data set to be extracted from certain documents. When the parsing engine receives a document in an input data stream, the associated filer is loaded and parses that document for the selected data set. Then another filer is loaded in response to another input document, and so on. The filers may be especially efficiently generated using an object-oriented approach and then dynamically instantiated at run time as may be conveniently achieved, for example, in the Java programming language.
