Patent CA-2501216-A1 (CA)
Inventor: BIEKER GUIDO
IPC: B61H7/08
Filed: 2003-10-03
Abstract: A magnetic rail brake for a rail vehicle is disclosed of the type comprising a magnet (5) supported from the rail vehicle a small distance above the rail (4). The magnet is supported by springs which are overridden on actuation of the magnet. A guide assembly guides the magnet for movement in a substantial ly vertical plane while allowing limited lateral movement. The magnet is provid ed with an extension arm (20) arranged to contact the rail vehicle at a distanc e from the magnet which is substantially greater than either the maximum exten t of vertical movement or the maximum extent of lateral movement. By controlli ng the motion of the extension arm within these limits of lateral and vertical motion, unwanted and excessive tilting of the magnet can be avoided.

Patent CA-2519318-A1 (CA)
Title: Burner assembly
Inventor: ALDRICH CHRIS
IPC: F23D14/02
Filed: 2005-09-14
Abstract: A burner assembly has a burner head and a deflector plate extending radially therefrom and across a firetube housing for supporting the burner assembly therein. The deflector plate has a plurality of angled vanes for re-directing secondary combustion air flowing through the housing. Secondary air is deflected away from a nozzle tip at the burner head to minimize lifting of the flame by the deflector plate or by a low pressure ring formed around the nozzle tip above the deflector plate for creating an area of low pressure.  Preferably, a combination of the deflector plate and low pressure ring provides a stable flame positioned at the nozzle tip under low-fire and high-fire conditions enabling use of a pilotless ignition and flame sensing system which is consistent under low and high fire conditions. More preferably, the deflector plate supports the igniter and optionally a heat return tube for heat tracing of the freeze-prone burner assembly components.

Patent CA-2528035-A1 (CA)
Title: File management method
Inventor: KIYAMA JIRO
IPC: G11B20/12
Filed: 2001-02-22
Abstract: When one recording medium is accessed from a multiple number of applications, the medium is usually divided into multiple areas. If this area division is performed and managed by partitioning, it is difficult to change the size of the partitions. Therefore, there has been the problem that the recording medium can not be used effectively. The recording medium is divided into multiple areas, and for each area, dummy data is written into the blank space in the area so that dummy data can only be overwritten using a particular application or with a file of a particular type. This configuration makes it easy to divide the medium into multiple areas and change the size of the areas.
