Patent CA-2177907-A1 (CA)
Title: Method and apparatus for gas flow modulated differential scanning calorimetry
Inventor: READING MICHAEL
IPC: G01N25/20
Filed: 1996-05-31
Abstract: A modulated differential scanning calorimeter ("MDSC") wherein the temperature of the sample and/or the reference is modulated by modulating the characteristics of a gas in thermal contact with the sample and or a reference.  In a first embodiment, the major heat flow path between the sample/reference and the furnace is the purge gas in the furnace chamber.  The composition of the purge gas in the furnace chamber of the DSC cell is modulated by alternately purging the DSC cell with a high thermal conductivity gas (e.g., helium) and with a low thermal conductivity gas (e.g., nitrogen), thus modulating the flow of heat to and from the cell. In a second embodiment, the sample and reference are heated (or cooled) by a temperature-controlling gas flowing around the sample and reference holders.  The gas is heated by being passed through a furnace before it flows around the sample and the reference.  The flow-rate of the temperature-controlling gas is modulated, thus modulating the temperature of the sample and the reference. The third embodiment is similar to the second embodiment, but in the third embodiment, the temperature (not the flow-rate) of the temperature-controlling gas is modulated.  The third embodiment preferably uses modulation furnaces which have a relatively low thermal mass, such that the sample/reference temperature can be modulated at relatively high modulation rates.

Title: Smoking object, packet that contains one or several of the smoking objects, and system for the user-production of cigarettes
Inventor: SCHWARB ALAIN
IPC: A24C5/40
Filed: 1996-08-21
Abstract: The application concerns a smoking object in non-smokable form with a wrapping-material sheet and with a tobacco layer applied to one surface of the wrapping-material sheet, which object is converted into smokable object, in particular a cigarette, through rolling up or twisting by the consumer. The wrapping-material sheet can be of cigarette paper and is then rectangular, for example, and has no adhesive strips on its long sides. The sheet can also have the form of a parallelogram with corners not equal to 90° . The depth of the tobacco layer can be uniform and ap- proximately correspond to the radius of the smokable object obtained through rolling up, or the tobacco layering is wave-like when viewed from the side. The wrapping-material sheet can also be of tobacco foil, with a tobacco layer located on only one of the surfaces. The invention concerns further a packet that contains one or several of the smoking objects in non-smokable form, as well as a system for the user-production of the cigarettes that includes one of the smoking objects in non-smokable form and a small cigarette- paper sheet or a (filter-) cigarette-paper sleeve.

Filed: 1997-04-24
Abstract: A novel plano lens and eyewear incorporating such lens is presented wherein the plano lens comprises a front surface curvature which is created by rotating an aspheric shape about an axis which is offset from an axis of the aspheric shape. In a preferred embodiment, the aspheric shape is an ellipse or at least is an aspheric shape, a segment of which has an elliptical arc. This elliptical arc is rotated about an axis spaced (offset) some distance from a major or minor axis of the ellipse. In a more preferred embodiment, the ellipse is rotated about an axis spaced from and parallel to the major or minor axis of the ellipse, but in the same plane as the ellipse. The resulting surface of this preferred lens configuration will have a cross section in a first axis which is a segment of an ellipse, and a cross section in a second axis (perpendicular to the first axis) which is a segment of a circle. A  significant feature of the preferred front lens configuration is that the surface generated is rotationally symmetric.
