Title: Stable operation of a smelter reactor
Inventor: DOWNING KENNETH B
IPC: C21B13/00
Filed: 1997-03-21
Granted: 2003-05-20
Abstract: A process of producing molten iron involves: a) introducing iron oxide, flux, oxygen, nitrogen, carbon, and hydrogen to a smelter reactor; b) maintaining conditions to cause (i) the iron oxide to be reduced, (ii) molten iron to be created and stirred in the bottom of the reactor, surmounted by a layer of foaming, FeO-containing slag, and (iii) carbon monoxide gas to rise through the slag; c) causing at least some of the carbon monoxide to react with the oxygen; d) releasing an offgas containing CO, CO2, H2 and H2O; and e) removing at least some of the molten iron and slag from the reactor. Good process stability is achieved by: f) repeatedly measuring, during the process, the conditions of the slag height, the temperature of the molten iron, the levels of CO, CO2, H2, and H2O in the offgas, the carbon level in the molten iron, and the FeO level in the slag, and g) subsequently adjusting one or more process variables (e.g., a reactant feed rate, the iron bath stirring rate, or the height of the oxygen lance above the slag) so as to help keep one or more of those process conditions within a predetermined range.

Abstract: An apparatus for determining the position and alignment of wheels, including  targets (130) for attachment to the wheels (112-115), a pair of optical sensing means such as television cameras (122, 124) for viewing the targets,  an electronic processing means connected to the optical sensing means for processing data relating to images of the targets to determine position and alignment information, and a display means for displaying the position and alignment information. The optical sensing means view a target and form an image. Electronic signals corresponding to each of the images are transferre d to the electronic processing means which correlates the image signals of eac h of the targets with the true shape of each target. The processing means relates the geometric characteristics and positional interrelationships of certain known elements of the target with corresponding elements in the view ed images and calculates the position and alignment of the wheels to which the targets are attached.

Granted: 2003-03-25
Abstract: Pixel information and control information transmitted by a facsimile machine 1a is received by a procedure controlling circuit 13 having a MODEM 13a for facsimile machines.  A facsimile procedure controller 14 decodes the pixel information and the control information.  A connection/transfer controller 15 edits the decoded information and produces a control packet and a pixel packet. The control packet and the pixel packet are output to a local area network (LAN) 4 via a LAN controller 17 and a LAN control circuit 18.  When receiving a facsimile, the control packet signal transmitted via the LAN 4 is converted into pixel control information by the connection/transfer controller 15, and the pixel control information is supplied to the facsimile procedure controller 14.  The connection/transfer controller 15 also converts the received pixel packet signal into pixel information. The pixel information is temporarily stored in a memory 16.  When a predetermined amount of pixel information is accumulated in the memory 16, said predetermined amount of pixel information is supplied to the facsimile procedure controller 14, and finally transmitted to the facsimile machine 1a via the procedure control circuit 13.

Inventor: HATA SATOSHI
IPC: B60N2/90
Filed: 1998-09-09
Granted: 2004-03-30
Abstract: Predetermined multiple points of the front passenger seat and its periphery are irradiated with spot beams, caught with a camera, and distances are measured based on the irradiation position of the spot beams. Conversely, the characteristics for each status of use of the seat such as the shapes of the contour of the seat or the contour of a child seat are detected from the picture information caught with the camera. The status of use of the seat is decided based the characteristics for each status of use and the distance information that was previously measured. Based on this decision, the operation of a passive safety device such as an air bag device is controlled.

Abstract: L'invention concerne une centrale électrique à cycle combiné, qui comprend une installation turbine à gaz (10) et une installation turbine à vapeur (40) associées, et dans laquelle la température de la vapeur de refroidissement est contrôlée de façon que la turbine puisse être fabriquée avec des matériaux faciles à se procurer. La vapeur provenant d'un évaporateur moyenne pression (26) est amenée à une conduite d'alimentation (14) en vapeur de refroidissement, qui amène un gaz de combustion provenant d'une turbine haute pression (41) à une partie haute température (11a) d'une turbine à gaz et servant de vapeur de refroidissement destinée à être mélangée audit gaz. On abaisse la température de la vapeur de refroidissement sans que cela diminue le rendement général, ce qui permet d'utiliser un matériau ayant une moins grande résistance à la chaleur pour former la partie haute température (11a) de la turbine à gaz qui est en contact avec une partie à refroidir. Un matériau relativement bon marché et facile à se procurer peut ainsi satisfaire aux exigences de la conception et de la fabrication.

Abstract: Methods and systems in a telecommunications system having a call forwarding service to connect an unanswered forwarded communication directly to a voice mail service of the called party. Upon notice that a communication for a subscriber has gone unanswered at a forwarded location, a call is placed to a code followed by voice mail information. As the call is routed, the code is recognized and the voice mail information is parsed into call instructions including a voice mail directory number as the redirected number. The call is further routed based on the call instructions until a recognition of the designated directory number in the call instructions results in call termination instructions. These instructions direct the serving switch to connect the call to the redirected number which is the voice mail service directory number. Once the call is connected to the voice mail service, the call is transferred to the unanswered forwarded communication so that the caller may leave a message in the voice mail service for the subscriber.

Title: Video-assisted apparatus for hearing impaired persons
Inventor: LAPALME MARIE
IPC: G09B21/00
Filed: 1998-05-26
Granted: 2003-09-16
Abstract: The apparatus for hearing impaired persons of the present invention comprises a telephone receptionist style headset which is to be worn by a speaker person on her head, in the conventional way. This headset is equipped with a frontwardly extending support arm which carries at its front free end a miniature camera (and also optional microphone) targetting the speaker's mouth. The camera is linked by a wire to a transmitter having intrinsic power means, which transmits the images caught by the camera by means of a wireless signal to receivers located remotely of the transmitter, e.g. on students' desks in a classroom. The receivers decode the signal and retransmits the images to television screens.  Thus, hearing impaired persons can observe the screens for performing lip-reading of the speaker person, so as to understand the conversation, even though the speaker's mouth may not be visible from the distance to these hearing impaired persons at any given time. Alternately, the camera could be shifted back over an ear of the speaker person, and a minor directed toward the camera placed instead ahead of the speaker's mouth, for reduced weight of the headset ahead of the teacher and therefore enhanced comfort by the speaker person.
