Title: Improvements relating to metal teeming
Inventor: GRIFFITHS WILLIAM ALBERT
IPC: F41B11/00
Filed: 1988-09-09
Abstract: A bottom pour molten metal containment vessel, e.g. ladle, has a pour passage which may experience temporary blockage which would prevent teeming when the valve (16) is opened, so to remove the blockage apparatus (30) is located in the path of teeming, aimed upwardly at the blockage. Apparatus (30) has a tubular barrel (32) lodged in the teeming path by holding means (40) and a short projectile (32') ejectable from the barrel. A high pressure gas supply (48) is connected via a valve (50) to the barrel for pneumatically propelling the projectile (32') at the blockage so as to impact thereon and bring about its breaching, removal or disruption. The projectile (32') is a solid body, or a closed hollow body filled e.g. with a reactive substance such as magnesium or a gas generating composition. Various specific forms of projectile are disclosed. <IMAGE>

Patent GB-2231457-A (GB)
Title: Phase-failure detectors
Inventor: BARNES JOHN
IPC: H02H1/00
Filed: 1990-04-02
Abstract: A circuit breaker incorporates three bi-metal strips 2, 3, 4 which bend due to the heat produced by current flow. Loss of current in one phase results in unequal bending of the strips. In one arrangement, a light-emitting diode 5 fitted to a first strip 2 causes light to pass through an aperture 8 in a plate 7 on the second strip 3 and to fall on a photo-sensitive detector 6 on the third strip 4. Any unequal bending causes the light to be cut-off and the resulting signal trips the circuit breaker 10. The strips may constitute the circuit breaker, and may be indirectly heated by coils 19a, 20a, 21a, or may be connected in the lines 19, 20, 21.

Patent GB-2249399-A (GB)
Title: Circuit test method
Inventor: MCKEON ALICE
IPC: G01R31/3167
Filed: 1991-04-09
Abstract: In a method of testing digital and analog circuits, stimuli are applied to first nodes of a circuit under test (CUT) (not shown), measurements are taken at second nodes of the CUT, and two possible values of a parameter at nodes of the CUT are derived by different methods of analysis. If the values are incompatible a fault is present in the CUT. The analysis is then repeated with the constraints of a selected part of the CUT removed and that part of the CUT is suspected to be faulty if the incompatibility is then removed. At least one further node is selected for measurement on the basis of calculated discrimination factors which depend on possible voltage ranges at unmeasured circuit nodes if various components are considered as faulty. Figure 2 shows possible ranges of values at nodes 2-9 of a CUT with the constraints of various parts of the CUT removed. <IMAGE>

Title: Circuit for compensating for the drop-out of a reproduced video signal
Inventor: HAN HONG-KYU
IPC: H04N5/94
Filed: 1991-09-23
Abstract: A drop-out compensator for a video reproducing apparatus comprises a switch means SW for selectively outputting a reproduced video signal and a 1H-delayed signal in response to a drop-out detecting signal, a 1H delay circuit 20 for delaying a video signal whose drop-out is compensated and which is output via the switch means SW, and an automatic level control means 100 for comparing the synchronous signal levels of the reproduced video signal and 1H-delayed signal, amplifying the 1H-delayed signal output from the 1H delay circuit 20 in response to the result of the comparison, thereby adjusting the level of the 1H-delayed signal to be supplied to the switch means SW to match that of the reproduced video signal. The compensator can automatically adjust the amplitude of a drop-out compensated signal by comparing the levels of the synchronous signal of a reproduced video signal and the synchronous signal of a 1H-delayed signal and matching the amplitudes of 1H-delayed signal and the reproduced video signal. <IMAGE>
Patent GB-2258417-A (GB)
Title: Mass production of discs from sheet materials with minimal waste
Inventor: BURROUGHS WILLIAM ERNEST
IPC: B21D28/06
Filed: 1992-01-31
Abstract: The process produces in two or more stages from strip 10 or sheet material circular discs, polygons or lobed shapes. The process applies to any malleable material and reduces the waste of conventional blanking. Asymmetrical squares or hexagons which tesselate are cut by progressive notching and/or cropping. The shapes give complete separation and permit errors in feeding the material. Waste only arises at the sides of the strip, in the case of hexagons. For malleable materials the parts are compression extruded between punch and dies considerably thinning, enlarging and forming the discs into circles, polygons or lobed shapes, within the die or punch profiles. Pressures of extrusion can be reduced by conically pointed punches. Conical indents in the discs can be avoided by special punches in which the conical points flatten due to the final high pressure. The punches are within the invention. For harder materials the parts are roll rimmed reducing the corners towards circular or lobed forms as desired. Alternatively the rounding can be done by punch and die sinking. Both techniques use special tooling within the invention. <IMAGE>

Title: Escape route guidance system
Inventor: JONES DEREK ANTHONY
IPC: G08B5/36
Filed: 1992-03-06
Abstract: A guidance system, particularly for guiding persons to a fire exit under conditions of darkness or poor visibility, comprises tactile guiding strips (3a, 3b) mounted along the walls of the building at a convenient height. The strips comprise lengths of fabric pile where the pile is inclined in a direction towards the fire exit 2. The pile therefore feels smooth when a hand is passed over it in a direction towards the fire exit, but feels rough when the hand is moved in a direction away from the fire exit. In conditions of poor visibility a person may thus find the fire exit by following the "smooth" direction of the strip. Other forms of surface shape or texturing may be employed to give the strip a different feel in opposite directions. <IMAGE>

Title: Aircraft system for computing yaw compensated angle of attack: stall warning.
Inventor: GREENE LEONARD MICHAEL
IPC: G05D1/06
Filed: 1993-03-12
Abstract: An aircraft system for computing a yaw compensated angle of attack includes an angle of attack sensor 2 for generating a signal which represents an aircraft's angle of attack as determined by an angle of attack vane 3 and a transverse accelerometer 5 for generating a signal in response to the lateral acceleration of the aircraft. A summing device 4 sums the two signals to thereby provide a yaw compensated angle of attack signal. The system may also include a rudder deflection sensor 6 for generating a signal which represents the deflection of an aircraft's rudder. The rudder deflection signal is then subtracted from the yaw compensated angle of attack in the summing device. A stall warning system incorporating the yaw compensation system includes a stall warning computer 7 for comparing the yaw compensated angle of attack signal to a predetermined value. The stall warning computer then triggers a stall warning device 8 when the yaw compensated angle of attack signal exceeds the predetermined value. <IMAGE>

Title: Erase unit for ion deposition web-fed print engine.
Inventor: POLLUTRO DENNIS C
IPC: G03G21/06
Filed: 1993-10-22
Abstract: An erase unit (24) for an ion deposition web-fed print engine (10) includes a plenum (26) extending the width of the electrostatic image on the image cylinder and defining an ionization chamber with the image cylinder (12) surface. The plenum has first and second electrodes (29, 31) separated by a dielectric (34). Upon application of a time-varying potential having a frequency of 0.2 to 50 mHz across the electrodes, ionization of argon gas fed through the hollow electrode (31) occurs, causing an ion current flowing in relation to the image surface until the image surface and the biasing electrode are at the same potential, thus erasing any residual electrostatic image on the cylindrical surface. By providing a DC biasing voltage, the residual electrostatic image may be erased when equalization occurs, with the image cylinder maintaining a pre-charged potential. <IMAGE>
