Patent CA-2179762-A1 (CA)
Title: Apparatus for the cleaning of dust laden gas
Inventor: DEHN GUENTHER
IPC: B01D46/24
Filed: 1996-06-21
Abstract: A filter for the cleaning of dust laden possibly hot gas includes ceramic filter candles which are closed at one end and positioned in multiple levels one above the other and are connected to laterally spaced apart candle supporting clean gas collectors. The collectors and the filter candles within one level form a filter module which is divided into several mutually separate filter segments in the shape of a circular sector. The collectors of each filter segment are connected to a clean gas collecting channel located on the same level.    A collector free space remains at the center of each module.      A cleaning lance protrudes into each clean gas collecting channel either directly or indirectly for the supply of pressurized, pulsed cleaning gas. This allows the groupwise cleaning of the filter candles and substantially reduces the amount of cleaning gas required for the cleaning of the whole filter unit.

Abstract: Tracheostomy tube assemblies may comprise an outer tracheostomy tube and an inner cannula, the outer tube being straight at its patient end and having a short straight machine end with a coupling. In the present invention, the inner cannula is of a flexible material preformed to the shape of the outer tube and smooth on its inside and outside. The patient and machine ends of the outer tube are separated by a curved intermediate region divided along its length into two sub-regions. The first sub-region closer the machine end has a small radius of curvature; the other sub-region closer the patient end has a radius of curvature at least three times that of the first sub-region. This shape enables the patient end of the assembly to be aligned with the patient's trachea.

Abstract: A first slidable auxiliary pinion (58a) on the bottom of a horizontally moveable elevator cab A (Figs. 2-6) disposed on a car frame (14) or a landing is moved out from under the cab toward another car frame (13) or landing by means of a motorized pinion (56) until it engages a motorized pinion (57) on the adjacent car frame (13) or landing, which then pulls the auxiliary pinion and the entire cab toward the other car frame or landing until a main rack (45) fixed to the bottom of the cab engages a motorized pinion (34) on the other car frame (13) or landing, which pinion then pulls the entire cab onto the other car frame or landing.  The auxiliary racks (58a, 58b) may be mounted on a common auxiliary rack member (58), or may be separate.  The auxiliary motorized pinions (55, 56, 57) may be bidirectional, or may be unidirectional and mounted on the same shaft with main pinions (32a, 32c; 33a, 33c; 34a, 34c).
Patent CA-2190045-A1 (CA)
Title: Customer activation system for cellular network
Inventor: HOLMES DAVID WILLIAM JAMES
IPC: H04M1/00
Filed: 1996-11-12
Abstract: A mobile communication terminal device such as a cellular telephone is provided with a preliminary identifier stored in memory. The identifier allows access to a cellular network for verification and provides essentially unique identification by the network, but is insufficient to allow further use of the network. During verification, the identifier is analyzed by a cellular network processor and a determination is made whether the cellular telephone should have restricted access to the network. Upon favorable completion of the identifier analysis, a signal may be transmitted to the cellular telephone that allows the cellular telephone to have less restricted access to the network.

Title: A method and device for partitioning physical netword resources
Inventor: BLAABJERG S REN
IPC: H04Q11/04
Filed: 1995-06-12
Abstract: A method for partitioning physical transmission resources of a physical network is provided. At first, a set of logical networks is established on top of the physical network. The logical networks comprise nodes and logical links extending between the nodes so as to form the logical networks. The logical links are used by routes. Next, the capacities of the logical links of the logical networks are determined such that the route blocking probability on each individual route in each one of the logical networks is less than or equal to a maximum allowed blocking probability, given for each individual route. This is realized by distributing, for each individual route, the route blocking evenly among the logical links used by the individual route. Finally, the physical transmission resources are allocated among the logical links of the logical networks according to the determination. In addition, a device for partitioning physical transmission resources of a physical network is also disclosed.

Title: Low power infrared scene projector array and method of manufacture
Inventor: COLE BARRETT E
IPC: H01L27/16
Filed: 1995-12-20
Abstract: An array for projecting thermal images and a method of making same. The array of the present invention combines a two-tier architecture created with special processing whereby each pixel member (12) resides on an elevated platform directly over discrete pixel control electronics (14) and electrically conducting traces couple a plurality of pixels so that they can be controlled to project thermal images at equal to or faster than video frame rates. Microlens assemblies coupled to each discrete pixel improves the thermal efficiency of the array for certain applications. In the method of fabrication, a semiconductor microbridge-type structure is obtained with the use of sacrificial layers under deposited pixel members in a compact array so that the pixel electronics reside beneath their associated pixel and the array electronics inhabit the same chip as the array thereby improving fill factor and time constant of the resulting array.

Abstract: A hanging structure for hanging an object such as a flower pot or the like from a gutter. The hanging structure includes an anchoring jaw. The anchoring jaw is formed of an integrally extending wire bent into a generally "U"-shaped configuration.  The inherent resiliency of the spring wire is used biasing the jaw towards an opened configuration wherein they frictionally engage the respective inner surfaces of the gutter walls. The hanging structure also includes a hook segment formed by the same wire being integrally bent into a generally "U"-shaped configuration.  The substantially "U"-shaped configuration of the hooking segment being in a substantially inverted orientation relative to the "U"-shaped configuration of the anchoring jaw.  The hanging structure further includes a substantially elongated spacing segment extending downwardly from the hooking segment. A hook having a substantially "U"-shaped configuration extends integrally from the lower end of the spacing segment for receiving the object being hung.  The hanging structure also includes a stabilising rod mounted on the anchoring jaw so as to abut against the edge of a roof. The hanging structure in mounted on the gutter by having the hooking segment abuttingly overriding the gutter front wall while the anchoring jaw is inserted within the gutter.  The jaws formed by the "U"-shaped anchoring jaws are biased against the inner surfaces of the gutter walls and the stabilizing rod abuttingly contacts the adjacent roof edge.
