Title: Sensing the level of molten metal
Inventor: KRUZYNSKI MARK T
IPC: G01F23/60
Filed: 1995-06-01
Abstract: A method and apparatus for casting molten metal in an opaque container 12 and for determining the level of the metal within the container. This is accomplished by locating a strain sensing transducer 34 over the container and metal, and sending a current pulse from the transducer along a wire 56 located in a tube 36 connected to the transducer and extending toward the vessel and molten metal. A permanent magnet 38 is located on a stem 40 connected to a float 43 within the container, whereby the magnet is displaced alone the tube 36 in dependence on the level of molten metal. A current pulse is sent along the wire 56 from the transducer, producing a magnetic field which interacts with the magnetic field of the permanent magnet 38. The interaction of the two fields exerts a strain on a fine tube (57, Fig. 3) around the wire within the tube 36, which strain is sensed by the transducer. The transducer also senses the time at which the current pulse is sent along the wire, and the time elapsed between the sending of the current pulse and the sensing of the strain on the tube indicates the level of molten metal within the opaque container. The occurrence of strain (torque) in the fine tube (57) is sensed by a pair of magnetic tapes (74) attached to diametrically opposite points on the tube and carrying sensor windings (76). <IMAGE>

Title: Correction of errors in a magnetic compass
Inventor: RUSTON FREDUN
IPC: G01C17/38
Filed: 1995-09-15
Abstract: A magnetic compass comprising an arrangement to displace a correcting marker to create a compass correcting coefficient equal to the sum of the variation and the deviation errors effecting the compass so as to counteract the compass error, and to indicate the true course. The correcting marker 4 becomes the steering reference and a vessel is steered so that the correcting marker is aligned with the true course to be steered by the vessel. Repeaters fed from this compass, which repeaters are fed by the hunting between the compass card and the displaceable correcting marker, indicate the true course as well as true bearings. The displacement of the correcting marker can be controlled from a computer programme, which displaces the correcting marker in dependence upon the effecting variation and deviation. Thus the magnetic compass shows true course and the repeaters show true course and true bearings automatically. Methods of steering a craft using a magnetic compass are also claimed. <IMAGE>

Title: Digital cursors for serial digital television waveform monitoring
Inventor: TALLMAN JAMES LARRY
IPC: G01R13/20
Filed: 1997-04-21
Abstract: Generation of digital cursors for serial digital television waveform monitors includes inputting numerical values, such as decimal or hexadecimal values, for the cursors by an operator via a front panel (FIG 2, 32). The numerical values are received by a microprocessor 30 which loads them into appropriate registers (FIG 3, 50) of a co-processor 20. The outputs of the cursor registers (50) in the co-processor 20 are input to respective inputs of a multiplexer (52) together with a digital signal representing a serial digital television signal 10. A select signal for the multiplexer is generated by a selection circuit (54) that is enabled by a digital cursor ON command when the waveform monitor is in a cursor mode. The selection circuit (54) at predetermined locations of the digital signal generates the select signal so that the appropriate cursor values are inserted into the digital signal at those locations. The processed digital signal from the co-processor is then converted to analog, filtered, 22 and displayed on a display device 26 to present a waveform representing the serial digital television signal together with the digital cursors.

Title: Device for deflecting a laser beam
Inventor: JURCA MARIUS
IPC: C04B41/50
Filed: 1997-07-04
Abstract: A device which is suitable for deflecting a laser beam, comprising a main body (2) made of a ceramic material with good thermal conductivity which provides a reflective surface (29) finished to a high optical quality. The reflective surface (29) is formed from a layer of a highly reflective material which is applied to the main body (2). The main body (2) may be composed from an aluminium oxide based ceramic material, and the reflective layer (29) may be produced from either copper, silicon, ZnSe or GaAs. The main body (2) may be formed in two parts (2a, 2b), where one of the parts (2a) is formed from the ceramic material and supports the reflective layer (29), and a cooling channel may be provided at the interface between the two parts in order to circulate a cooling fluid in the body. The use of a ceramic body (2) with a good thermal conductivity seeks to overcome the problem of surface deformations which are caused by the laser beam and which impair the quality of the laser beam. The ceramic material also provides a lighter device and one which may be more easily fixed to a supporting structure with a reduced risk of damage. A method and a process of producing such a device are also disclosed.

Title: Load balancing in a distributed computer enterprise environment
Inventor: BEREITER THOMAS WILLIAM
IPC: H04L12/56
Filed: 1997-09-18
Abstract: A method of balancing loads during data distribution in a managed network environment wherein at least one gateway machine services a plurality of endpoints. System management tasks include data distributions, which are normally initiated at the gateway (source node) and distributed to all managed endpoints EP1-EP14. Load balancing is achieved by setting a load parameter for each subnet A-G of each network path between the gateway machine and an endpoint machine serviced thereby. The load parameter is selectable and identifies an amount of network bandwidth that may be used by a particular data distribution over the segment. Prior to initiating a distribution, the effective load that a given subnet will "see" when the operation begins is then calculated. If that effective load for any subnet exceeds that subnet's respective load parameter, the data distribution rate is altered for the overall network path. This technique effectively balances network loads and makes more efficient use of resources.

The table 5 is again moved to the left side, so that each workpiece W is subjected to a boring process by the cutting tools P and Q. The workpiece carry-out device 7 receives the processed workpieces W, and then the workpieces W are unloaded by a workpiece unloading device 4, and are fed to a subsequent step.

Title: Seat belt buckle
Inventor: HARRISON MARK JOHN
IPC: A44B11/25
Filed: 1998-06-05
Abstract: A seat belt buckle for use with a tongue 16, includes a frame 10, in which is mounted an ejector 20, operable by an ejector spring 22. Insertion of the tongue pushes a retainer 30 down a track 26, against the action of a retainer spring 32. The track is inclined at an angle a to the path 15 of the tongue and extends outwardly away from the path in the direction of insertion of the tongue. When the tongue has been inserted an adequate amount, the retainer 30, e.g. a ball returns up the ramp under the influence of the spring 32 and engages in an aperture 18 in the tongue to retain the tongue in the locked condition. Operation of a release mechanism (42, Fig 5) disengages the retainer from the aperture thereby to release the tongue.
