Title: Charge pump circuit having protection leakage elements
Inventor: PENNOCK JOHN
IPC: H02M1/32
Filed: 2008-12-30
Abstract: This invention relates to charge pump circuits having circuit components SS1-4 - LS1-4 such as transistors which may be damaged by voltage transients greater than the normal operating voltage levels of the charge pump circuit, such as may be experienced during powering down. The circuit components to be protected are connected in parallel with a leakage element D1-4 arranged to have a leakage current that is small enough during normal operation to allow the charge pump to operate effectively but which is large enough, during development of a voltage transient, to prevent excess voltage levels being achieved. The leakage element may have a significant leakage current at a voltage less than the breakdown voltage of the circuit component. The leakage elements may be poly diodes 20.

Title: Resolution reduced video monitoring method to enable real time video processing
Inventor: NIEM WOLFGANG
IPC: G06T3/40
Filed: 2009-04-07
Abstract: A device and method for reducing the resolution of an input image G showing a three-dimensional scene which is captured by a monitoring camera 3, characterised in that the resolution reduction is dependent on the object distance in the 3D scene and/or the perspective distortion of the 3D scene. The object distance is the distance between the camera and the scene objects in the 3D scene. Areas of the image with a large object distance have their resolution reduced less than the areas of the image with a small object distance so that distant objects and close objects that are the same size have a similar resolution for subsequent object segmentation, object following or motion detection 10. The resolution reduction may be adjusted by analysis of camera parameters, by modelling a scene reference model and/or a datum plane or by combining with other pre-rectifications of the input image. The distorted and resolution-reduced input image may be used for image analysis where object-describing metadata is formed. This resolution reduction method enables real time video processing because it reduces the processor load by undersampling in the resolution uniformly in the horizontal and vertical directions before image processing.

Inventor: DAY EDWARD CHARLES
IPC: G01C9/12
Filed: 2009-07-22
Abstract: A device is provided for aiding the levelling of a caravan, mobile home, trailer, or chassis. The device is placed on a flat, horizontal surface within the caravan or trailer. The device comprises a pendulum 2 mounted on a stand 3 which points to a scale 4 which provides a direct reading of how much a wheel of a caravan or trailer must be raised so that the caravan or trailer is level. The pivot point and length of the pendulum 2 are adjustable by means of a slot and scale 1, and holes 5 to account for different wheel spacing of the caravan or trailer. The scale 4 is magnified by a lens 6. The trigonometry of the device is thus related to the caravan or trailer such that the height of the pivot point and scale reading of the pendulum point are two sides of a triangle which is similar to a triangle of which the wheel spacing and difference in wheel heights form two sides.

Title: Battery power supply
Inventor: HIGGINSON MARK CHRISTOPHER
IPC: F03D9/02
Filed: 2009-12-21
Abstract: A power supply arrangement comprises a power storage device such as battery 10; a generator capable of charging the battery, such as solar panel 24, wind turbine 26 or man-powered bicycle training machine generator 28; and a power consuming device such as television 18 supplied via an inverter 30 and plug 20. A controller such as computer 32 determines whether the power storage device 10 is used to power the consuming device and prevent power being supplied by the battery when the stored power is below a threshold, during a certain period such as when the solar panel is charging it, or when low power, for standby, is required. The controller can also warn when the battery charge is low, allow discharge to start only when charge is sufficient, and only permit one supply to supply power at a time, using switches 14, 16. The controller can monitor the duration or times of supply, the power supplied by the battery 10 and mains 12 and the state of charge. The power supply can be portable, have more than one removable battery, supplying power in turn, and more than one power consumer can be supplied simultaneously, via sockets.
Patent GB-2476509-A (GB)
Title: Turbine with reduced thrust coefficient at excessive speed
Inventor: KING JEREMY
IPC: F03B13/26
Filed: 2009-12-24
Abstract: A turbine such as a tidal turbine comprises blades that are shaped so that thrust coefficient decreases significantly beyond the first rotational speed up to a runaway speed for the turbine assembly. The blades may have an enlarged chord and/or angle of twist compared with a blade which is optimised for power coefficient. This may result in a slight decrease in power output for equivalent blades, but a much lower thrust coefficient in runaway conditions, so that excessive load is not transferred to the support structure. This provides passive over speed control, and may reduce or eliminate the need for variable pitch control or braking systems.

Title: Ultra-short wave generator
IPC: C01D3/06
Filed: 1934-04-04
Abstract: 423,832. Valve generating circuits. NAAMLOOZE VENNOOTSCHAP MACHINERIEEN-EN APPARATEN FABRIEKEN, 30, Croeselaan, Utrecht, Holland. April 4, 1934, No. 10276. Convention date, April 4, 1933. [Class 40 (v)] Current or voltage is supplied to an intermittently-operative short-wave oscillator from a condenser-relaxation oscillator. As shown, the relaxation oscillator comprises a pair of condensers C, C<1> charged through choke coils D, D<1> from the centre-tapped secondary of a supply transformer Tr. The condensers discharge in turn through discharge tubes Th, Th<1> and through the respective halves of an output coil L, which is connected through an amplifier, transformer, or other element N to a potentiometer H. A vibrating-electron shortwave oscillator R has its plate A and grid G connected to opposite ends of this potentiometer, its cathode K being connected to a tapping. The Specification indicates by curves, Fig. 1, (not shown), the relations between the amplitudes and phases of the grid and plate voltage for obtaining the greatest frequency change and maximum energy output, and in practice a compromise between these conditions is adopted. In applying the invention to magnetron oscillators, a relaxation oscillator is employed for supplying anode voltage, and current for the magnetizing-coil. The supply system may also be employed for back-coupled oscillators. The supply may be of audiofrequency, and the oscillations may occupy only a small fraction of the supply cycle.

Title: Improved means for analysing gaseous substances
IPC: G01N29/02
Filed: 1951-05-04
Abstract: An instrument for determining the nature of a gas comprises a self-excited oscillator supplying electrical energy to one or more sending transducers adapted to transmit sound energy through a vessel containing a variant gas, one or more receiving transducers for the sound energy transmitted, and means for comparing the electrical signals received as regards phase and amplitude with those obtained by the passage of sound energy through a datum gas. The presence of methane and carbon dioxide in the atmosphere of a mine may be detected.  The instrument may be made of portable size by employing ultrasonic frequencies.  As shown, high frequency alternating current is supplied by an oscillator 10 to transducers 11, 16; perforated tube 13 is accessible to the gas being tested, and sealed tube 18 contains a known gas; sound energy is converted back to electrical energy by transducers 12, 17.  A difference in velocity through the tubes causes a change in phase relationship in the outputs of 12, 17, which is measured by phase meter 14 comprising a ring modulator; attenuation of the sound energy causes an amplitude difference of the outputs measured by a voltmeter.  The measuring means may comprise a relay-operated signalling device.  Apparatus is described in which the two tubes are arranged side by side in a box and a water wick maintains a constant <PICT:0727891/III/1> moisture condition in the gas being tested.  In alternative forms of apparatus (a) the tubes are in line with a double-diaphragm transducer arranged between their ends; (b) the tubes are formed by bores in a single body, and a transducer, separated from the bores by a diaphragm, is arranged at each end of the body; (c) the tubes are curved and their ends are connected to two double-diaphragm transducers.

Title: Improvements in and relating to baking apparatus
IPC: C23D5/00
Filed: 1927-04-20
Abstract: 269,900. British Thomson-Houston Co., Ltd., (Assignees of Heisler, C. L.). April 22, 1926, [Convention date]. WiTe enamelling ovens; air, preventing admission of. - Relates to ovens for baking varnish, enamel, &c., on material which is continuously passed therethrough, e.g. on wire or cambric, and comprises means for maintaining uniform temperature conditions throughout the length of the oven. In the apparatus shown wire from drums 17, 18 is passed over idler pulleys 19, 20 through enamel baths 27, and then vertically through the oven 10 where the enamel is baked. Preferably the wire receives a number of coats of enamel and is passed through the oven a corresponding number of times before being finally wound on the drums 25, 26. The oven is heated by heater elements 13, 14, 15, 16 each consisting of a sinuous tube 65, Figs. 6 and 7, having a combustion chamber 61 at its lower end fired by a gas burner 64. The tube may be built up of cast sections held together by bolts 66, and its upper end is open so that the products of combustion pass into the oven. The lowermost heater element is fired at a somewhat higher temperature than the remainder, and it is surrounded by a casing 68 so that the wires are protected from the more intense radiation. Horizontal baffles 67, 69, which may be more closely spaced towards the lower part of the oven, are fitted to obstruct the upward flow of gases. Products of combustion are withdrawn from both ends of the oven by a fan, and dampers 33, 36, Fig. 4, are provided in the outlet ducts so that a substantially uniform temperature can be maintained over the whole length of the oven. The gases are cooled by water sprays 37, 38 before passing to the fan, and at the lower part of the suction box 30 a series of horizontal baffles 30<a> is fitted to cause intermingling of the hot gases with water from the spray 38. At the lower end of the oven are three groups of baffle plates 41, 42, 43, Fig. 5, spaced apart to form slots 46, 47 through which the wires pass. The baffle plates of the outer groups have upwardly bent edges 48, while those of the inner group are fitted with downwardly inclined hinged flaps 50. At the upper end of the oven are two groups of baffle plates 52, 54, those of the upper group being arranged step fashion as shown in Fig. 4. These baffles tend to prevent entry of air to the oven, and any air which mav pass through the slots for the wire will be drawn off to the fan with the heating- gases.
