Abstract: Procédé de production de fonte brute liquide ou de produits de départ liquides en acier à partir de matière contenant de l'oxyde de fer, selon lequel de la matière sous forme de fines particules contenant de l'oxyde de fer est réduite en éponge de fer sous forme de fines particules à l'aide d'un gaz de réduction dans au moins un étage de réduction (7, 8) par le procédé à lit fluidisé, et des blocs de minerai sont réduits en blocs d'éponge de fer dans un étage de réduction à lit fixe (28). L'éponge de fer est introduite dans une zone (11) de gaséification par fusion et y est fondue, avec ajout simultané de supports de carbone et de gaz contenant de l'oxygène. On obtient ainsi un gaz de réduction contenant CO et H¿2?, destiné à la réduction de la matière contenant de l'oxyde de fer. Pour éviter que l'on ait à traiter séparément l'éponge de fer sous forme de fines particules et les blocs d'éponge de fer, on introduit l'éponge de fer sous forme de fines particules et à l'état brut directement dans la zone (11) de gaséification par fusion et on l'y fait fondre avec les blocs d'éponge de fer.

Title: Electromechanical cylinder lock
Inventor: HURSKAINEN OIVA
IPC: E05B49/00
Filed: 1999-03-17
Abstract: An electromechanical cylinder lock includes a lock body and a turnable lock cylinder and a locking mechanism inside the lock body. The locking mechanism normally prevents turning of the lock cylinder relative to the lock body and can be moved by means of a key of the lock to a releasing position allowing turning of the lock cylinder. The key for the lock includes a transmitter for transmitting an electronic code and the lock correspondingly includes a receiver for receiving and identifying the code of the key.      When the receiver detects the correct code the receiver enables mechanical opening of the lock by means of the key.      The lock includes a locking disc with a key opening which is so designed that the turning of the key does not directly act mechanically on the locking disc. The lock also includes a coupling element for coupling the locking disc to the turning movement of the key. The lock is provided with electric operator which is activated by means of the electronic code from the key and which in an active state controls the coupling element so that the locking disc turns with the key to a position required for opening of the locking mechanism.

Patent CA-2266866-A1 (CA)
Inventor: BORDOGNA MARK ALDO
IPC: H04L12/56
Filed: 1999-03-25
Abstract: A simple, elementary switch fabric is provided for switching individual signals as a composite group based on goup signal status that is embedded and carried within each of the individual signals in the goup. In general, a group signal status is derived for a group based on the signal status of each of the individual signals within that group. This group signal status is then individually encoded and embedded in each of the individual signals in the goup. The embedded group signal status can be extracted and decoded at any point within the transmission path, as necessary, to facilitate appropriate switching decisions. Although each individual signal is switched independently by the elementary switch fabric, the individual signals are effectively switched as a composite goup because the switching decision for each individual signal in the group is based on the same group signal status. That is, individual signals in a particular goup will either be selected or rejected together as a single, composite group.

Title: Self-evacuating vacuum cleaner
Inventor: SEAHOLTZ CRAIG A
IPC: A61L2/14
Filed: 1997-10-06
Abstract: A vacuum cleaner has an electric motor driving an air impeller (74) for creating suction and a pump (104) which draws liquid material through an inlet tube from the bottom of a tank and expels it from the tank (32). The vacuum cleaner also includes a mechanical shut-off and override assembly (144) that automatically shuts off the motor if the liquid level in the tank gets too high. A user, however, can mechanically override this automatic shut-off in order to continue pumping liquid out of the tank (32). A priming apparatus is disposed in the tank in fluid communication with the pump, and a valve is selectively actuable to establish a pressure differential across liquid in the priming apparatus to thereby prime the pump.

Title: Hydrogen fueled power plant
Inventor: YANG WEN CHIN
IPC: F01D25/12
Filed: 1997-08-13
Abstract: A power plant that combusts hydrogen with oxygen in a high pressure combustor (2) to produce steam, which is mixed with cooling steam (30) before being sent to a high pressure expander (12), which expands the steam and generates rotating shaft power. The expanded steam is mixed with steam from the combustion of hydrogen and oxygen in an intermediate pressure combustor and expanded in an intermediate pressure turbine (14), thus generating more rotating shaft power. The steam from the intermediate pressure turbine is fed into a heat recovery steam generator (18) that cools the steam and heats water streams to form cooling steam (58) for at least one of the turbines and the combustor. The now cooled steam exits the steam generator and passes through a low pressure turbine (20), thereby generating more rotating shaft power, and is condensed into the water streams for heating into cooling steam in the steam generator.

Abstract: A method for switching transmission devices to an equivalent circuit for the bidirectional transmission of ATM cells.      The prior art for the switching of ATM cells to an equivalent circuit involves the problem of incorrect switching operations. The method according to the invention provides a remedy for this by virtue of the fact that when there is a fault on a service link an equivalent circuit switching operation onto just one standby link is controlled in accordance with priority criteria and logic operation information.

Title: Method for separating mixtures of substances using a material pervious to said substances
Inventor: HOERPEL GERHARD
IPC: B01D46/42
Filed: 1998-09-18
Abstract: The present invention relates to a method for separating mixtures of substances using a material which is pervious to said substances. The use of this material for separating substances comprises briefly applying a voltage on the material, which substantially increases the efficiency of substance separation methods such micro-filtration or ultra-filtration. The material used as a membrane can be purified in different ways by applying a voltage thereto, the separation capacity being thus increased while providing an even cleaning of the membrane. The material used as a membrane can also be heated by applying a voltage thereto so as to increase the transfer of matter through the membrane. This method can be used for separating substances in various gas or liquid mixtures as well as in solutions.

Patent CA-2277391-A1 (CA)
Inventor: KNIGHT KEITH ALAN
IPC: G02B6/38
Filed: 1999-07-15
Abstract: A fiber optic connector is provided which includes a free floating ferrule so as to reliably withstand significant side-pull forces. In other words, the fiber optic connector is designed such that the minimum rotational angle of the combination of the ferrule and the pin clamp within the connector housing is greater than the maximum rotational angle of the connector housing within an adapter. In order to permit the ferrule to be free floating, the fiber optic connector can provide increased clearance or spacing between the combination of the ferrule and the pin clamp and the connector housing. For example, the inner sidewalls of the forward end of the connector housing may have either a beveled or a stepped profile in longitudinal cross-section so as to provide additional clearance at the forwardmost portion of the ferrule. The combination of the rear end of the ferrule and the pin clamp can also have a beveled profile so as to provide clearance at the rearwardmost portion of the ferrule and pin clamp combination.      Similarly, the inner sidewalls of the connector housing proximate the rear end of the connector housing can also be tapered at an angle of at least 2° to provide additional clearance.
