Title: Transmission for scooters and other vehicles
Inventor: MERCIER CHRISTIAN
IPC: F16H61/662
Filed: 1999-04-23
Abstract: The driving pulley (12) is used in a continuously variable transmission (CVT) and comprises two flanges (22, 24) around which a drivebelt (20) is partially wound. The first flange (22) is fixed in translation with reference to the drive shaft (16) while the second flange (24) is movable, with reference to the first flange (22), between a distal position and a proximal position. The driving pulley (12) is provided with an arrangement which allows the return force on the second flange (24) to be maximum when the second flange (24) is at the distal position, and minimum when the second flange (24) is at the proximal position. The driving pulley (12) is also capable of being disengaged from the drivebelt (20) at a low rotation speed. This driving pulley (12) is particularly well adapted for use on a scooter.

Title: A method for determining access time of repeatedly broadcast objects
Inventor: BITTNER RUDOLF
IPC: H04N7/088
Filed: 1999-05-19
Abstract: Broadcast based information systems like Teletext use a unidirectional communication scheme in order to get access to information. This means that requests for data objects are not transmitted from a client to a server.  Instead the receiver part of the client has to listen for the requested object on the broadcast medium and copy it to the local storage when it goes by. The access time from the receiver point of view is defined as the difference between the reception point in time of the object and the point in time when the request was made. Nowadays realized broadcast based information systems are not able to determine precisely when a requested object will be available. The present invention uses a repetition distance which defines an additional parameter which has to be transmitted with each broadcast data object at the transmitter side. The receiver can use this information to determine the precise repetition point in time of a requested object. This information can be used to realize a progress indicator, so that a user can be informed about the time he has to wait for the requested object. Also, this information is essential for the realization of certain caching strategies.

Title: Ostomy or incontinence pouch
Inventor: STEER GRAHAM E
IPC: A61F5/445
Filed: 1999-12-21
Abstract: An ostomy pouch (10) is defined by a front wall (12) and a rear wall (14) having a stoma aperture (18). One or more rupturable capsules (24) are carried on a carrier or intervening wall (44) welded to the front and rear walls at a common weld seam (16). When desired, a capsule (24) can be ruptured by squeezing, the pouch wall together at that position, to dispense the contents (for example, a deodorising agent, a disinfectant or a preservative). In one form, the carrier does not cover the stoma aperture. In another form, the contents are dispensed on the side facing the front wall (12), and the curtain (44) shields the stoma aperture (18), to prevent the agent spurting out or contacting the stoma. In another form, one or more rupturable capsules may be arranged on the front wall (12) or on the rear wall (14). A plurality of the capsules (24) may contain different agents if desired. In another form, one or more self-dissolving capsules, for example, of gelatine, may be introduced into the pouch to dispense the agent in response to environmental conditions (for example, temperature/humidity) within the pouch.

Filed: 1998-06-09
Abstract: A device for implanting small diameter conductive leads for an artifical cardiac pacemaker or other body-implantable medical device includes a stylet (22) for guiding the lead along a predetermined path within the patient's body. At least a portion (25, 27) of the stylet which is to traverse the path has an enhanced radiopaque characteristic attributable to the application or addition to the material of which the stylet is composed of a substance having such radiopaque characteristic. When viewed under fluoroscopy external to the patient's body as the lead is maneuvered along the path, although the thin lead itself may be difficult to see, the stylet is readily discernible by virtue of its enhanced radiopacity, thereby enabling the physician to position the lead at a desired location within the patient's body. For various reasons,the thin lead itself may not be amenable to similar enhancement, which makes the stylet a suitable solution. A portion of the distal end of the stylet, such as its distal tip (25) or a plurality of spaced apart points (25, 27) along its distal end, is provided with the enhanced radiopacity, as by application or addition of gold to the stylet material.

Title: Method and apparatus for generating numbers to play in a lottery
Inventor: HALL EDGAR ROBERT JR
IPC: G07C15/00
Filed: 2000-09-07
Abstract: A method and device for generating hot sheets for lottery numbers based upon previously drawn numbers and astronomical data. A player selects at least one number for input. The input number is then searched for in a database containing historical data of at least one comparison lottery including the number and date of previous draws. It is then determined when the number selected by the user was previously drawn in the comparison lottery by accessing the comparison lottery database. A second database, which is also accessible by the device, which may be a part of the first database, contains data regarding the timing of certain astronomical events, such as planet aspects, planet ingress, moon ingress, and the phases and eclipses of the moon. Time gaps between the time of the previous drawings of the number selected by the player is determined, such as by using the dates immediately before and after the dates the number previously fell. Based upon these time gaps hot numbers are determined for each of the astronomical events, such as the number corresponding to the smallest and largest time gaps for each event. These numbers are then displayed on a display and/or printed on a sheet of paper as a "hot sheet" to be used in selecting numbers for play in a lottery.
