Patent GB-2270439-A (GB)
Title: Chromakey method and apparatus for picture signals
Inventor: GEHRMANN RAINER
IPC: H04N5/275
Filed: 1993-08-27
Abstract: A chromakey method in which fading operations are performed between the picture signals in proportional zones in dependence upon a control signal, while intermediate colors occurring in the porportional zones in the foreground signal are transformed into new intermediate colours which constitute a transition from the color of the foreground picture signal to that of the background signal. An optimal adaptation of the proportional zone to the respective colour location of a foreground picture signal region is ensured by determining individually the distance between the colour location of the region and the colour location of the key colour and generating a control signal each region dependent upon this distance. <IMAGE>

Title: Defect detection using an indicator fluid
Inventor: YOUNG PETER DAVID
IPC: G01N21/88
Filed: 1996-10-04
Abstract: In some types of non-destructive testing, an indicator fluid (e.g. a dye) is applied to a cast, forged or machined metal article (after washing the article) and allowed to penetrate into cracks or other flaws in the article. After excess indicator fluid has been removed, the indicator fluid still remaining in these tiny flaws can be seen and allows the flaws to be observed by an operator. The invention addresses the problem of poor drying after the initial washing stage (and the resulting blockage of recesses in the article under test, preventing penetration by the indicator fluid) by using a reduced pressure (at least a partial vacuum) to draw washing fluid away from and out of the article under test.

Patent GB-966261-A (GB)
IPC: H04L1/04
Abstract: 966,261. Telegraphy. GENERAL ELECTRIC CO. Ltd., W. J. BATTELL, G. W. DANN, and G. H. PELLS. Sept. 29, 1961 [Oct. 18, 1960], No. 35775/60. Drawings to Specification. Heading H4P. In a data transmission system each block of data to be transmitted is divided into a number of groups of data signals and the groups are transmitted simultaneously over a corresponding number of voice frequency channels. At the receiver the groups are combined to reproduce the original block of data. The recurrence frequency of the data signals is too high to allow transmission over any one channel. In the embodiment described, a block of 52 digits, plus a 4-digit address, a 5-digit instruction signal, and 5 spare digits, is fed in parallel from a computer to a shift register. Parity bits are derived by circulating the data stored in the register and counting the number of, for example, mark pulses in a certain predetermined number of sequential data pulses. Six parity bits are added to the register in this way so that the register holds a total of 72 bits. The register is connected to 18 further registers, each to hold 4 digits, so that digits 1-4 are held by one register, digits 5-8 by the next &c. Four read-out pulses now cause the 18 registers to be read out simultaneously, the data pulses being applied to frequency modulate 18 voice-frequency channels-the transmission path may be a land-line or a radio link. At the same time a further set of 4 signals, forming a " start " signal, is transmitted over a further channel. A pilot tone may also be transmitted in order to allow partial compensation for any overall frequency shift that may occur. At the receiver the start of the start signal, which signal is sent via the fastest channel, initiates the reading in to a set of 19 four-digit registers of the signals received on the 19 voicefrequency channels. Coincidence gates check that the address and the start signal have been correctly received, whereupon the data from the 17 remaining registers is fed simultaneously to a 68-digit register. The parity of the stored digits is checked by means of associated circuitry, an alarm being operated if necessary. Finally, the instruction digits and the data digits are read out from the 68 digit register for utilization. To enable more data to be signalled in a given time, three separate sets of voice-frequency equipment are used, successive blocks of 72 digits being fed to each set in turn and the three sets of 19 four-digit groups being transmitted, overlapping in time, over three land-lines. Specifications 922,063 and 966,262 are referred to.

Title: Motion compensated video signal processing
Inventor: DAVID MORGAN WILLIAM AMOS
IPC: G06T7/20
Filed: 1993-08-19
Abstract: In a motion compensated video signal processing system, each correlation surface is combined with a group of correlation surfaces from surrounding search blocks (each correlation surface representing the correlation between a search block of one image with a search area in a subsequent image) to generate a plurality of combined or grown correlation surfaces and a motion vector is generated from each of the original and combined correlation surfaces. Each correlation surface is subjected to an array of delays, delays 650 being equal to the transmission time for one correlation surface, whilst the row delays 660 correspond to the transmission time of a row of correlation surfaces. The outputs of each of the delays in the array are therefore identical points in the surfaces. The outputs from selected delays are normalised and combined (Figure 16) to generate, as described, five combined correlation surfaces (Figures 4B - 4F), form each of which a motion vector is generated.

Title: Pressure compensation system for a packer
Inventor: CORONADO MARTIN P
IPC: E21B33/12
Filed: 1998-01-28
Abstract: A pressure-compensation system is in fluid communication with the annular space between the body of the packer or plug and the inflatable element. The compensation system responds to thermally induced pressure load changes within the wellbore by allowing fluid to escape from beneath the inflated element when increases in fluid temperature in the wellbore increase the pressure under the element. The system additionally supplies fluid behind the element should the wellbore fluids decrease in temperature, thus lowering the pressure under the inflatable element. When the packer 12 is expanded pressure passes along passage 18 to move piston 48. This moves until it contacts piston 60. Fluid in cavity 54 is vented via ports 70. If there is a further pressure increase due to a temperature rise piston 48 moves piston 60. This causes fluid in chamber 72 to pass along passage 74 and through one way valve 90. The fluid is accomodated by movement of piston 88. If there is a temperature fall fluid can pass along passage 90 and through one way valve 100 to move pistons 60 and 48 to push fluid into the packer.
