Title: System and method of displaying information by an electronic price label
Inventor: ZIMMERMAN TERRY L
IPC: G06Q20/20
Filed: 2000-01-19
Abstract: A system and method of displaying information by an electronic price label which uses thresholds to minimize the number of messages to an electronic price label. The system includes a record for an item associated with the electronic price label which contains the thresholds. The thresholds divide the information into a number of ranges including a first range of information and a second range of information. The system further includes a computer for scheduling messages for transmission to the electronic price label, wherein the computer obtains first information associated with the first range and displayed by the electronic price label, obtains second information which is more recent than the first information, determines whether the first information equals the second information, and if the first information does not equal the second information, obtains the second range, determines whether the first information is within the second range, and sends a message to the electronic price label containing the second information and a command to display the second information instead of the first information if the first information is outside the second range.

Title: Lockdown mechanism for well tools requiring fixed-point packoff
Inventor: DALLAS L MURRAY
IPC: E21B33/043
Filed: 2000-02-29
Abstract: An apparatus for securing a mandrel of a well tool in an operative position in which the mandrel is packed off against a fixed-point in the well is described. The apparatus includes a mechanical lockdown mechanism to secure the tool to the wellhead and maintain the mandrel in proximity to the fixed-point for packoff, and a mechanical or a hydraulic mechanism to move the mandrel into the operative position while the mechanical lockdown mechanism is in a lockdown position. A second mechanical locking mechanism is provided to ensure the mandrel is maintained in the operative position in the event that hydraulic pressure is lost. The invention provides a mechanism to lock down well tools requiring fixed-point packoff in a well and advantageously improves the range of adjustment of the lockdown mechanism so that the length of a mandrel may be less precisely matched to a distance from a top of the wellhead to the fixed-point in the well.

Title: Dynamoelectric machine rotor ventilation
Inventor: FERGUSON JAMES HAROLD
IPC: H02K9/12
Filed: 2000-10-26
Abstract: A dynamoelectric machine has a stator member, a rotor member, a first shroud and a second shroud. The first shroud and the second shroud members are mounted to the rotor adjacent respective first and second end portions of the rotor for rotation with the rotor. The first and second shrouds extend radially over and are spaced from the respective radially extending first and second end portions of the rotor to respectively define radial inlet and outlet paths therewith. The first and second shrouds each have a first radially inner end adjacent and spaced from the shaft to define a gas inlet or outlet, respectively, and a second radial outer end mounted to the rotor adjacent and spaced apart the ventilation ducts for communicating gas between the ventilation ducts and the inlet and outlet paths. The second outlet shroud is spaced further from the shaft than the inlet shroud so as to facilitate the gas flowing in the inlet shroud and out the outlet shroud during normal machine operation. Fan motors are provided at the inlet and outlet of the shrouds to direct gas flow. The present invention provides for an improvement in windage loss by angularly accelerating the gas prior to entering the ventilation ducts of the rotor and an additional improvement by partially reclaiming energy at the outlet shroud energy by angularly decelerating the gas flow.

Abstract: A method and apparatus for enabling background caching of encrypted programming data on a storage medium for later playback in a digital video recorder (DVR) system. A set-top box (STB) equipped with a DVR searches a program guide for upcoming pay-per-view (PPV) events. When the PPV event begins, the STB tunes an appropriate transponder and begins receiving programming data packets containing audio, video, system time and conditional access data packets associated with the event, which are stored for playback on a storage medium. When the user turns the STB on and selects an option to playback a previously-recorded PPV event, the appropriate programming data is retrieved from the storage medium, and the STB recreates the original transmission timing of the data, to be displayed on a display device of the user.

Title: System and method for enhanced short message service
Inventor: ALPEROVICH VLADIMIR
IPC: H04W4/029
Filed: 1999-03-31
Abstract: A telecommunications system and method is disclosed for organizing SMS  messages sent to a mobile terminal based on the location of the mobile terminal or the time of delivery of the SMS messages. Thus, when a subscriber sends a short message to another subscriber, the originating subscriber can specify the time of delivery of the message. In addition, the originating subscriber can specify the priority associated with the message, e.g., the SMS message can have an indication of priority one, which indicates to the receiving subscriber that the message is urgent. Furthermore, the originating subscriber can also specify that the message is to be delivered only when the called subscriber is in a certain location. The receiving subscriber can also control the display of the SMS messages by moving the received SMS messages to an action list, and then specifying when and/or where the SMS  messages should be displayed again.
Patent CA-2326766-A1 (CA)
Inventor: FRIDE ESTHER
IPC: C07C43/15
Filed: 1999-03-30
Abstract: The present invention relates to a compound of the general formula (I) which is a non-hydrolysable analogue of endogenous cannabinoids, which are found to be more potent therapeutic agents as they are more stable, for example, to hydrolytic cleavage in the gastrointestinal tract. The cannabinoid analogues of the invention have a therapeutic value. Therefore, pharmaceutical compositions comprising as active ingredient a therapeutically effective amount of at least one compound of the invention may be prepared. Such compositions may be used as anti-inflammatory, anti-asthmatic, analgetic, hypotensive, antiemetic or anti-spasmodic compositions, and as compositions for treating and/or preventing glaucoma or migraine, or as compositions for relieving symptoms of multiple sclerosis and mood stimulating compositions.
Patent CA-2326773-A1 (CA)
Title: Selective blocking in a communication network
Inventor: MAZZARELLA NICK J
IPC: H04Q7/36
Filed: 2000-11-24
Abstract: A selective blocking request is sent from a requesting network element to an SCF (system control function component), where the request identifies a targeted network element. The SCF may then block communications from the targeted network element to the requesting network element, or it may send an ACG (automatic code gapping) message to the targeted network element requesting it to stop sending communications to the requesting network element. This technique offers the advantage of allowing an overloaded network element to reduce its workload while informing other components of the network that messages from a targeted network component will not be accepted by the overloaded network element.

Title: Method for producing a rim hole
Inventor: PLANK OTTO
IPC: B21D39/03
Filed: 1999-01-15
Abstract: With previously known riveting methods for joining a pile of plate-shaped work pieces, material of a work piece lying on the outside is pulled through pre-drilled holes of the other work pieces and subsequently the part of the rim hole protruding out over the latter work piece is flanged. A disadvantage with this is that separate pre-drilling of work pieces is complicated and expensive. The new process is supposed to reduce the number of work steps, make the individual work steps easier and thus make the process less expensive and more effective. In addition, the connection is supposed to be accomplished flush to the surface. According to the invention, in a single feed movement of a rim hole punch, both the rim hole is formed from the one work piece as well as the openings in the other work pieces by breaking out one or more pieces of material.      Producing a rim hole.
