Patent GB-945302-A (GB)
Abstract: 945,302. Control of motors. N. F. HECTOR, and K. J. ASTROM. April 6, 1960 [April 9, 1959; Sept. 24, 1959], No. 12668/60. Heading H2J. [Also in Division G1]. Relates to a device for increasing the inherent moment of inertia of a rotatable system 1 comprising an electric motor 5 coupled to a tachometer generator 2, in which the generator feeds current back to the motor through differentiating device 3 and amplifier 4. The output voltage of the amplifier, representing the acceleration of the system, is phase-displaced by 180 degrees with regard to its input voltage, the motor torque opposing an external torque to increase the moment of inertia of the system. In another arrangement, the deflection of gyroscope 24 is proportional to the angle of displacement of a rotatable system 21, a device 26 generating a voltage proportional to such angle. This voltage is double-differentiated, amplified, and applied to motor 30. If a restraining force increasing linearly with the deflection angle of the gyroscope is developed between axis 25 and platform 22, the voltage produced by the device 26 becomes proportional to the angular velocity of the system 21. A single differentiation only is then necessary. The restraining force may be produced by a resilient member or a torque motor 31 which is supplied with the amplified voltage from the device 26. In other modifications, the output of the device 26 is made to be directly proportional to the angular acceleration of the system 21, the feedback voltage to the motor 31 being proportional to the velocity of the system. The device 26 may be replaced by a tachometer generator.

Title: Improvements in or relating to the dispensing of fluids
Inventor: SCARFFE MICHAEL FREDERICK
IPC: B67D1/00
Filed: 1993-07-27
Abstract: A system for dispensing mixed beverages has a processor (6) to control the liquid dispensed at an outlet (2) in dependence upon the demand of a user as input to a keypad (8). Carbonated water is fed to the outlet (2) by way of tubing (12) and a syrup concentrate is also fed thereto by way of a tubing (20). The water and syrup is mixed in the correct quantities by way of respective proportional valves (14) which adjust the quantity or flow rate of the two constituents fed through a mixing chamber (16) in accordance with flow rate readings provided to the processor (6) by respective flow transducers (22). The flow transducers (22) measure the speed of flow ultrasonically and are able to provide flow rate readings at a rate of 50 per second. The proportional valves (14) are able to adjust the quantities fed to the mixing chamber (16) at a similar rate such that the mix can be reliably determined even if there are transitory pressure drops or viscosity changes in the system. <IMAGE>

Title: Automatic curve-fitting
Inventor: KOEHRSEN CRAIG L
IPC: G06F17/17
Filed: 1995-08-21
Abstract: A B-spline curve is automatically generated in a processor as an approximating curve to a set of data points. A set of four control points are selected (104) at equal intervals along a path defined by the data points. A B-spline curve generated (108) using these control points is compared (112) to the path to determine the separation (116) between the curve and the path. If the separation exceeds a threshold separation, then one or more control points are added (118) and the curve regenerated. The process of adding control points continues until the curve approximates the path within a specified level of separation. A control point is then removed (120) from the solution and the curve is regenerated (124) and again compared (128) to the path. If there is no adverse effect, the control point is left out (136) of the solution. If there is, however, that control point is returned (140) to the solution. This process of checking a control point to determine whether it can be removed is repeated for the remainder of the control points. The path may be a route followed by a sea-going vessel or by a dump truck in an autonomous mining operation. <IMAGE>

Title: Source voltage generating circuit
Inventor: KANG BOK-MOON
IPC: G11C5/14
Filed: 1996-04-26
Abstract: An internal source voltage generating circuit for a semiconductor memory device comprising a feedback unit 11, 12, 13, 14 in the form of a differential amplifier connected between an external source voltage EVcc and a current control node N4, receives the internal source voltage IVcc output from node N2 and a reference voltage Vref and regenerates the internal source voltage in accordance with the difference between the two voltages. A mode control signal * capital Greek phi *CTL turns on NMOS transistor 31 during a self refresh operation in a self refresh mode, lowering the resistance of the current path between node N4 and ground potential Vss and thus increasing the DC current in the differential amplifier. This allows rapid recovery of a change in the internal source voltage output. In all other modes transistor 31 is turned off to reduce current consumption.

Title: Apparatus for determining position of moving body
Inventor: MURAYAMA OSAMU
IPC: G05D1/02
Filed: 1994-12-06
Abstract: It is the object of the present invention to correct deviation of a guided moving body by dead reckoning before and after each round of a lane to precisely guide it. When the moving body (1) travels on a lane (L3), the positions of two reference points (R11) and (R12) immediately forward the start point (P3) of the lane (L3) are calculated as the positions on coordinates x-y. When the moving body completes one round of the lane (L3) and continues to run, the positions of the two reference points (R11) and (R12) described above are again calculated as the positions (R'11, R'12) on the coordinates x-y. Deviations of the position and travelling direction of the moving body (1), that occur while the moving body (1) is running the lane (L3), are corrected on the basis of the positions of these two reference points so calculated and the estimated position and estimated direction Pe (xe, ye, * small Greek theta *e) when the moving body (1) returns to the start point (Ps) after each round.

Title: Verifyng  that a stored cryptographic key has not been altered before allowing its use
Inventor: JAMES ANDREW LEWIS
IPC: H04L9/00
Filed: 1997-11-26
Abstract: The current application is designed to defend a secret stored key K against external attack. It is possible to attempt to determine the value of a secret stored key by inputting the same number time and again and monitoring the resultant output while progressively modifying the stored key by external means (eg. microwave bombardment). The current application attempts to foil this approach by checking that the key K remains unchanged using a stored check value D which has a known relationship to the stored key K. If either the stored key K or the stored check value D becomes corrupted then the known relationship breaks down and encryption using the key K is prevented.

Title: Thickness meter for thin transparent objects
Inventor: COHEN GIL
IPC: G01B11/06
Filed: 1998-05-28
Abstract: A thickness meter uses a single fibre confocal method for direct measurement of the distance between the focal points of the beam on the top and bottom surfaces of a lens 30 or object being measured. A light source transmits illumination down an optical fibre 14 to a movable focussing head 18, which focusses the illumination from the end of the fibre onto the object to be measured, and focusses illumination reflected from the object back to the end of the fibre. The end of the fibre 16 thus acts as the pinhole aperture for the confocal effect. A directional coupler 12 is located in the optical fibre, for diverting illumination reflected from the lens or specimen to a detector. This detector detects the maxima which occur as the focal point passes through the surfaces of the object, and the object thickness is calculated therefrom.

Filed: 1998-06-30
Abstract: An optical device (S1) comprises at least one waveguide core (K) which is provided with an incident end (4a) through which light enters the optical device (S1), and an emergence end (4b) through which light emerges from the optical device (S1). Between these two ends (4a, 4b), a slit (6) is provided across the waveguide core (K) and an optical element (12) is installed within this slit (6). The core size of the waveguide core (K) varies such that the slit (6) is smaller in size than either of the incidence (4a) or emergence (4b) ends. This means that the mode field size of the light beam travelling through the optical device (S1), is larger in the slit (6), than it is at either the incidence (4a) or the emergence end (4b) of the waveguide core (K). A bulk non-reciprocal polarising rotator and a bulk reciprocal rotator may be mounted in the slit (6), and an optical fibre (8) may be provided at the incident end (4a) and/or the emergence end (4b) of the waveguide core (K).

Title: Off-line teaching apparatus
Inventor: KANEKO MASAKATSU
IPC: B25J9/22
Filed: 1998-09-04
Abstract: The apparatus receives commands via input devices 12,14 and modifies a robot model which is displayed on the monitor 26 according to the commands. The commands which are input are successively stored in a buffer before execution of the commands. The number of commands awaiting execution in the buffer is counted, and when the number is at least a predetermined value, a sound is produced 28,30 when the next command is input to the buffer. This informs the operator that the command has been accepted by the system, but there may be a delay in its execution, reducing the risk of re-entry of the command. Other or additional features described are a system which determines the point on the model where the command is to operate, and features of the display such as magnification and viewing direction, so that the displayed image is modified correctly. A second feature provides an insensitive zone about a desired direction of movement, so that movement within the insensitive zone that is not in the desired direction of movement is not permitted.
