Title: Tundish outlet edge seal and riser for continuous casting apparatus and method
Inventor: KEY JAMES C
IPC: B22D11/06
Filed: 1993-07-23
Abstract: A method and apparatus for continuously casting metal includes a tundish having edge seals and risers positioned at an outlet portion thereof. The edge seals and risers are configured to reduce the depth of molten metal adjacent the tundish sidewalls such that a lesser volume of molten metal contacts a driven casting surface to permit rapid solidification of edge portions of a cast strip. The edge seals and risers also are configured to form a meniscus between the seals and casting surface to effectively seal a gap between the tundish sidewall and continuous casting surface to prevent molten metal leakage therethrough. Preventing molten metal flow through the gap between the casting surface and sidewalls eliminates the requirement for a mechanical seal during continuous casting of molten metals.

Patent CA-2107269-A1 (CA)
Inventor: MRAZ WILLIAM B
IPC: F16J15/43
Filed: 1993-09-29
Abstract: Abstract A ferrofluidic seal is fitted with a centering ring having an inner edge adapted for engagement with a rotating shaft for centering the seal about the rotating shaft.  The centering ring automatically engages the shaft and centers the seal when the seal is fitted onto the shaft.  The centering ring is affixed to the housing, and/or magnet and pole module.  In one embodiment, the centering ring may be removed after it performs its centering function.  In another embodiment, the centering ring is non-removable and remains within the seal permanently.          According to this latter embodiment, the centering ring serves the additional purpose of retaining ferrofluid, expelled from the seal during "bursting", within magnetic reach of the seal so as to be re-drawn into the seal, thus extending seal life.          Additionally, a ferrofluid retaining ring absent a centering function may be employed.  The centering ring provides for easy installation and accurate centering of a seal with which it is used, and yields a highly functional and operationally safe seal.

Patent CA-2113584-A1 (CA)
Inventor: CROWLEY CHRISTOPHER W
IPC: A61B5/055
Filed: 1994-01-17
Abstract: A remotely positionable device  for use  in magnetic resonance imaging includes a magnet which is juxtaposable against the object to be imaged without actually surrounding the object.   When so positioned,  the magnet generates a static nonhomogeneous magnetic field having a determinable measurement  surface  wherein both  the  magnitude  and  the gradient   of   the   field   are   substantially   constant.          Additionally,  the  device  includes  an  RF  antenna  for periodically pulsing nuclei in the measurement surface with pulses of the Larmor frequency to initially tilt the nuclei and to subsequently refocus the nuclei.   The device also includes a pair of gradient coils which generate a gradient fields that are superposed on the static field to encode the nuclei.  The RF antenna subsequently receives a plurality of encoded spin echo signals from the refocussed nuclei which are averaged by a computer to create a measured response.          Specifically, the nuclei are refocussed and the encoded spin echo signals are received at a rate that is proportional to the gradient of the static flux field.  The computer is also used  to  create  an  image  from  a  plurality  of  measured responses taken from differently encoded spin echo signals.

Title: Continuous forming of complex molded shapes
Inventor: JACOBSEN THEODORE L
IPC: B29C48/08
Filed: 1992-10-06
Abstract: A continuous length or flow of a malleable or fluent material is provided to a forming apparatus which shapes the material, producing a contiguous series of smoothly blended, properly contoured portions of the desired shape. The formation of a shape relies on continuous control of shape-determining variables: instantaneous cross section of the shape in a virtual transition surface between the formable and formed material, rate-of-change of cross sectional dimensions between sequential cross sections, instantaneous angle of movement of the material at any point on the cross section in the transition surface, and rate of movement away from the transition surface of the just-stabilized portion of the shape.  The material is stabilized as these shape-determining variables achieve the proper values in each portion of the material.  Analyzing and modifying a computer model of a desired shape, and developing a process control datafile from the models.
