Title: Rigid continuous casting starter bar with flexible end for storage
Inventor: BEHRENDS GUNTHER
IPC: B22D11/08
Filed: 1993-02-09
Abstract: A starter bar (20) for continuous casting has a free end portion (40) which is flexible for storage and a substantially rigid portion (36) at the end which plugs the mold (24). The starter bar (20) is constructed in discrete blocks (60, 62, 63) secured to one side of a planar spine (61, 64, 66) provided in segments and arranged end to end. Spacing means adjustable spacers in the form of tapered blocks (92) are disposed between the blocks of the bar (20) to allow the starter bar (20) to be self-supported in a curved configuration corresponding to the casting path. A more flexible spine (66) in the end portion (40) of the starter bar (20) allows the starter bar (20) to be curved to a tighter radius than that of the casting path while the blocks (62) fan out in an unsupported configuration. A storage ramp (46, 48) is provided to support the flexible end (40) in the stored position.

Patent CA-2137705-A1 (CA)
Title: Lubricated Means for Slack-Free Railcar Connections
Inventor: KAUFHOLD HORST T
IPC: B61G7/10
Filed: 1994-12-09
Abstract: Slack-free or slackless coupling systems have application in various types of coupling arrangements such as drawbars, articulated connectors, and E and F type couplers. The gravity wedge that takes up any slack developed when the system components wear, maintains a constant longitudinal force on the follower block and coupler member butt-end interface. However, under high buff loading, that mated interface develops high friction forces during curving and angling. It has been found that the lateral component of these friction forces can become great enough to cause wheel lift at the wheel/rail interface. The present invention reduces that component of friction by greatly reducing the coefficient of friction at the coupler/follower block interface by supplying a lubricant between these surfaces. The present invention incorporates a series of lubrication retention reservoirs in the follower block front face to hold and distribute lubricant such that each time the coupler member butt-end laterally and vertically angles, lubricant within the reservoirs is wiped out of the reservoirs. The reservoirs are large enough to hold enough lubricant until the car is serviced for maintenance. Alternatively, a manual or automatic lubricant supply system can be used in conjunction with the follower block to ensure that lubricant is always held within the reservoirs.

Inventor: HOFFMAN CARVEL D
IPC: G01B15/04
Filed: 1993-08-02
Abstract: The present invention relates to a computer tomography system which measures the thickness and edge position of hot-rolled steel. X-rays produced by two X-ray sources are directed, through the sample being measured, to a plurality of radiation detectors. The radiation detectors measure the attenuation of the X-rays caused by the sample. The attenuation levels sensed by each detector are correlated with each detector's physical location. This information is collected as each X-ray source illuminates the radiation detectors. The collected information is triangulated or averaged, as necessary, to determine the dimensions and position of the measured sample.

Patent CA-2161168-A1 (CA)
Title: Optical fiber cable for underwater use using terrestrial optical fiber cable
Inventor: BLEE JOHN JAMES
IPC: G02B6/44
Filed: 1995-10-24
Abstract: An underwater optical fiber cable is constructed from a terrestrial optical fiber cable by hermetically enclosing the terrestrial optical fiber cable with a hydrogen barrier such as a copper tube or by using a terrestrial optical fiber cable having a hydrogen barrier therein, and by wrapping at least one layer of galvanized armorwires outside of the hydrogen barrier. As so reinforced, the terrestrial optical fiber cable has the strength needed for an underwater optical fiber cable by using relatively inexpensive galvanized armor wires. Although the galvanized armor wires generatehydrogen by contact with water, this hydrogen is prevented from adversely affecting optical fibers in the terrestrial optical fiber cable by the presence of the hydrogen barrier. Advantageously, a standard terrestrial optical fiber cable can be chosen from the many types available including high fiber count designs. Therefore, the flexibility of the core terrestrial cable choices permits system optimization and compatibility of underwater cores with shore cables without a proliferation of limited underwater cable designs. Also, the terrestrial optical fiber cable can be selected to include nohydrogen-generating material inside of the hydrogen barrier. Thus, the optical fiber cable of this invention will inherently have greater long-term reliability and, in the event of a rupture or leak in the hydrogen barrier, will last longer than optical fiber cables using hydrogen-generating material inside of a hydrogen barrier.

IPC: G01V3/02
Filed: 1996-02-27
Abstract: Apparatus for monitoring particles in fluid systems in which a detector has electrical contacts that are bridged by particles captured from suspension in the fluid. Upon detection of a particle, a control microprocessor stores a predetermined quantity of electrical energy on a capacitor, which is then discharged through an inductor to burn off the particle at the detector. The burn-off charge and return lines from the charge storage capacitor are un-grounded, and are connected by respective electronic switches through relay contacts to the conductors connected to the chip detector. The relay contacts are also connected to the inputs of a differential amplifier for detecting presence of a chip bridging the detector contacts and monitoring continuity of the conductors to and from the detector. The relay is powered by system voltage, and in the event of system power failure connects the chip detectors directly to warning lamps on an operator panel.

IPC: G01V1/28
Filed: 1995-02-10
Abstract: A method for efficiently and accurately producing filter coefficients for wavefield extrapolation which is particularly useful for migrating seismic data using a multiprocessor  parallel  computer as  provided.  In 3D seismic migration, the techniques have been  developed for 3D  processing using  ID  extrapolation filters.  The present  invention uses a  Remez-type  approximation  for developing such extrapolation filters which increases image quality or reduces processing  time, or both. Additionally, the method provides an  automated  method  for  producing such extrapolation filters which is  particularly  useful in parallel seismic migration  because of the  large  number of  extrapolation filters which  must be  produced.  The automated method of generating filters  sets  a frequency transition band where the amplitude is specified  to  be monotonically decreasing which insures stable filter design.

Abstract: A fuel delivery system for delivering fuel from a fuel tank to an internal combustion engine has a fuel pump with a pump inlet and a pump outlet, a fuel reservoir with a reservoir outlet, and a chamber connecting the pump inlet with the reservoir outlet. A reservoir supply valve between the reservoir outlet and the chamber is moved between an open position in which fuel flows from the reservoir to the chamber and a closed position in which fuel is prevented from flowing from the reservoir to the chamber, by a fuel level sender having a float arm which depresses or releases a plunger extending from the reservoir supply valve. A float attached to the float arm rises and falls with changes in fuel level within the fuel tank so as to contact the plunger and thus move the valve between the open and closed position when the tank fuel level is below and above, respectively, a predetermined level.
