Patent CA-2147548-C (CA)
Title: Nestable stent
Inventor: RUDNICK JAMES J
IPC: A61F2/06
Filed: 1995-04-21
Granted: 2004-08-31
Abstract: An intraluminally implantable stent is formed of helically wound wire. The stent has a generally elongate tubular configuration and is radially expandable after implantation in a body vessel. The wire includes successively formed waves along the length of the wire.      When helically wound into a tube, the waves are longitudinally nested along the longitudinal extent of the stent so as to form a densely compacted wire configuration.      After radial expansion the stent maintains high radial compressive strength and wire density to retard tissue ingrowth.

Abstract: A train of rectangular pulses is sent into a fibre (5), which pulses have such a wavelength that fibre (5) operates under anomalous dispersion conditions, such a peak power as to cause modulation instability in the fibre and such a ratio between duration and repetition period that the average power is lower than the threshold at which stimulated Brillouin effect takes place. The maximum value of instability gain is measured in the spectrum of the pulses exiting the fibre and the kerr non linearity coefficient is is obtained from the maximum measured value of modulation instability gain by minimising the error, in the range of power values used for the measurement, with respect to a theoretical curve expressing such maximum gain as a function of the peak power. The device to realise the method is also provided.

Title: A system for and method of dispensing lottery tickets
Inventor: STOKEN RAYMOND G
IPC: G07C15/00
Filed: 1996-09-11
Granted: 1999-06-29
Abstract: A lottery ticket dispensing system is for improved pull-tab lottery tickets of atype that include a plurality of normally closed windows that can be opened to reveal play symbols thereunder with some of the play symbols being winning symbols. Each of the improved lottery tickets is also provided a normally closedbar code window with bar code markings hidden thereunder which includes ticket information for indicating each of the play symbols as aligned with its respective window. A lottery ticket dispensing machine includes a ticket storage area and means for initiating the dispersing of the ticket from the storage area toward the front panel of the machine. When the ticket is being dispensed, the bar code window is opened and the bar code revealed thereunder is aligned with a bar code reading device that is operably connected to electronic control circuitry of the machine that receives and stores the ticket information included in the bar code markings of the dispensed ticket. The front panel of the machine includes aplurality of display areas and associated switches that correspond to the windows of the ticket. Selective activation of each switch causes the electronic controlcircuitry to generate a display symbol in the corresponding display area which indicates the play symbol that is under the selected window of the ticket. The ticket information also includes winning information to provide a separate winning display area on the front panel when any of the play symbols are winning symbols. If the play symbols are not winning symbols, bonus winning markings may be added to some of the regions of the ticket but not shown on any display screen to encourage the opening of all of the windows of the tickets that are dispensed even if they do not include any winning display symbols.

Title: Process and device for coating a substrate surface
Inventor: LOHWASSER WOLFGANG
IPC: H01J37/305
Filed: 1997-01-09
Granted: 2001-08-14
Abstract: In a process for coating a substrate surface with a layer of inorganic material (38), the inorganic material is vaporised in a vacuum chamber evacuated to at least 10-3 mbar by bombarding with an electron beam from a high voltage electron-beam gun (10) and deposited on the substrate surface. Gas discharging is created between the point of incidence (A) of the electron beam (16) on the inorganic material (38) to be vaporised and an anode (20) such that the electrostatic charge created by the high voltage electron-beam gun (10) flows off via the anode (20). This way damage to the substrate, which may arise as a result discharging phenomena, can be effectively avoided.

Abstract: There is disclosed a soft and compliant spacer body wherein the body is provided with modified substrate engaging surfaces to accommodate transverse dimensional changes when the spacer is bent about a corner or otherwise flexed in an insulated assembly. In one embodiment, the corners are cut to reduce the thickness of the strip as the same is bent or flexed about a corner. Other embodiments aredisclosed. The advantage is that when the transverse dimension is maintained relatively constant about the bent corner, the result is a more effective seal between the substrate engaging surfaces and the substrates. This is augmented by the use of cellular materials and selected sealants to provide multiple sealing surfaces in a high efficiency spacer body.
