Patent CA-2340903-A1 (CA)
Inventor: SOLLARS JOHN A JR
IPC: B60R21/232
Filed: 2000-06-15
Abstract: L'invention concerne des tissus gonflables revêtus (26), notamment des airbags sur lesquels des faibles quantités additionnelles de revêtement ont été appliquées, et présentant des perméabilités à l'air extrêmement faibles. Les tissus de l'invention sont principalement destinés à être utilisés dans des coussins de sécurité d'automobile nécessitant des caractéristiques de perméabilité faibles (tels que des airbag latéraux). Habituellement, des couches lourdes et onéreuses de composés, tels que le néoprène, les silicones et similaires, sont utilisées pour que les faibles niveaux de perméabilité requis soient atteints. Ainsi, l'airbag revêtu de l'invention possède un revêtement d'au plus 2,5 onces par yard carré, et idéalement d'environ 0,8 once par yard carré, et présente un temps d'échappement (mesure du temps requis pour que la quantité de gaz introduite dans l'airbag à une pression de pointe pendant le gonflement s'échappe de l'airbag à 10 psi) d'au moins 7 secondes. L'invention concerne tous les revêtements, notamment les revêtements élastomères, non siliconés, et les airbags remplissant ces conditions.

Patent CA-2350242-A1 (CA)
Inventor: SMITH BRAD
IPC: G01R22/06
Filed: 1999-11-24
Abstract: An improved process ensures to the extent possible that the usage memory of an electronically-based electricity meter is always in a state that most recent data may be retrieved. Two separate areas or pages of memories are maintained and updated as to quantitative consumption, i.e. kilowatt-hour. The older of the two data memories is updated, based on a data validation check. The approach ensures that a previous value is always retained, to prevent full data loss in the event that the power goes down. If one area of memory becomes corrupted, the other value can be retrieved and verified so as to prevent loss of both memory areas, before a subsequent data reading (such as kWh or a unit of time for a kW reading). Use of a relatively small unit of measure prevents significant adverse data loss, since any data lost is limited to the chosen unit of measure since the most recent update.

Title: Pseudo-reflective read inhibitor for optical storage media
Inventor: HELLER ADAM
IPC: G11B7/24
Filed: 2000-03-23
Abstract: Systems and methods are described for inhibiting the readability of an optical storage media (200) due to changes in a pseudo-reflective material that composes the optical media (200) after the optical media (200) has been exposed to air for a predetermined time. An optical media (200) includes a data encoded element (220). At least a fraction of the data transforms from a substantially optically reflective state to a substantially optically non-reflective state as at least in part a function of time from an initializing event.

IPC: F15B15/26
Filed: 2002-04-08
Abstract: A lock for securing the head of a fuelling machine, defuelling machine or inspection machine to the end fitting of a fuel channel of a nuclear reactor is a rod and piston lock which engages or disengages according to the differential between the pressure in the snout cavity and the pressure in the fuelling machine magazine. The lock is engaged when the snout cavity pressure and the fuelling machine pressure are substantially equalized. When the pressure in the snout cavity is reduced sufficiently below the level of the pressure in the fuelling machine, the lock is engaged. The lock remains engaged if there is a drop in reactor pressure during refuelling and during reactor shutdown conditions. Engagement of the lock prevents inadvertent unclamping of the fuelling machine from the fuel channel.
