Title: Method and system for foreground detection using multi-modality fusion graph cut
Inventor: CHANG FELIX L
IPC: G06V10/28
Filed: 2009-04-29
Abstract: A method for foreground detection using multi-modality fusion graph cut includes the following steps. A foreground region in a video frame is designated 430 using an adaptive background Gaussian Mixture Model (GMM) and a threshold value. The foreground region containing at least one object block is segmented 450 using a multi-modality fusion graph cut procedure. Information regarding each block is saved and compared 433 with the GMM; when a trend in a change is detected by the GMM the GMM is updated. The GMM may be updated via a Kalman filter 436. The designated foreground is segmented via a graph cut process 450. The graph cut process may utilize a Markov Random Field (MRF) graph model 451. The cut algorithm is adapted to minimize an energy function.

Title: Improvements in processes for purifying gases containing hydrogen sulphide from hydrogen sulphide
IPC: C10K1/12
Filed: 1934-04-03
Abstract: In purifying gases from hydrogen sulphide by washing them with an alkaline liquid, e.g. alkali carbonate solution, and regenerating the washing liquid by the introduction of carbon dioxide followed by the removal of hydrogen sulphide and carbon dioxide, carbon dioxide from a previous cycle of the process is introduced into the spent washing liquid while maintaining the hydrogen sulphide in the liquid and first the hydrogen sulphide, and then the carbon dioxide, is removed; the regenerated liquid and the carbon dioxide being returned to the process.  The solution containing hydrogen sulphide may be treated with carbon dioxide in a closed container, the carbon dioxide being forced in below, at or above atmospheric pressure.  The sulphuretted hydrogen may then be removed by means of a vacuum at ordinary or slightly increased temperature after which the solution may be boiled to drive off the carbon dioxide and regenerate the solution. Specification 190,115, [Class 1 (ii)], is referred to.
Patent GB-731997-A (GB)
Title: Apparatus for distilling water containing impurities
IPC: C02F1/04
Filed: 1953-04-13
Abstract: <PICT:0731997/III/1> In a device for using solar heat for generating electricity and distilling water, e.g. sea water, the liquid passes to a conduit 6, having air-removing bells 29, from a reservoir 7 to a basin 17 covered by a dome of resiliently-mounted glass panels 20 from which a duct 9 leads vapour, produced by the sun's rays passing through the glass, to a high level condenser 12.  Furthermore, a pump 28 removes air from the condenser while liquid condensed by a cooling coil 26, e.g. potable water, passes through a conduit 13 to a high level storage reservoir 14 from which it may be run to generate electricity.  A turbine 10 driven by the passage of the vapour moves an electric generator 11, which, however, before starting the device, is used as a motor so that the turbine withdraws air from the basin 17 and draws liquid up the conduit 6. A closed-ring duct 8 with a check valve 23 in one vertical section and bearing fins 8a extends from the reservoir through the basin 17 and contains liquid which by thermo-siphon action transfers some heat from the reservoir to the basin to replace that lost by evaporation.  The glass panels are coated with nitrides to increase the transmission of sun's rays therethrough.  Any residue, e.g. salt if sea water is used, is drawn off from the basin 17 to a vessel 16a through a valved pipe 16.  The device may also be used for cooling only, by covering the glass panels 20 if necessary with vanes 20a and by driving the turbine 10 to create a vacuum in the basin 17 and cool the liquid therein by evaporation, the liquid in reservoir 17 then being cooled by the thermo-siphon 8.

Title: Accounting machine
Filed: 1964-03-10
Abstract: 992,453. Magnetic record-card machines. NATIONAL CASH REGISTER CO. March 10, 1964 [April 5, 1963], No. 10047/64. Heading G4M. An accounting machine comprises at least one transducing head co-operating with a magnetizable record medium, the path for conducting the operating potential to the head including a pair of electrical contacts, one being fixed and connected to the transducing head, the other being movable and connected to the potential supply, there being provided a potential-responsive device connected to the fixed contact and rendered conducting when the fixed and movable contacts fail to make proper electrical contact thereby actuating an indicator and/or locking the machine. The arrangement described is adapted for use with the accounting machine disclosed in Specification 852,827 in which transducing heads co-operate with magnetizable strips on the rear of ledger cards, and provides a means of checking that the potential supply to the transducing heads is effectively connected thereto. As shown in Fig. 1, an accounting machine comprises a plurality of transducing heads 32 each energized via a supply lead including cam-actuated contacts SC101, each supply lead being connected also, at a point 20, to a potentialresponsive device in the form of a transistor 54, the arrangement being such that during an auxiliary cam cycle of the accounting machine in which data erasing and recording takes place, all the transistors 54 are normally non-conducting due to the potential supplied via the closed contacts SC101. However, if effective contact is not made at any of the contacts SC101, e.g. due to the presence of dirt, the corresponding transistor 54 is rendered conducting thereby causing a power transistor 62 connected in common to all the transistors 54 to conduct. Conduction in transistor 62 is effective to operate a relay K403 which holds over contact K403AC1 and is effective to operate an indicator lamp and to energize a further relay (Fig. 3, not shown) thereby disabling circuits to prevent further operation of the machine.

Filed: 1932-04-08
Abstract: 399,855. Reproducing music. JONES, W. B., 38, South Dearborn Street, Chicago, U.S.A. April 8, 1932, No. 10100. [Class 40 (iv).] To reproduce musical and similar sounds binaurally, the sounds are picked up by two microphones arranged at the same distance apart as human ears, the two inputs are transmitted over separate channels to the left and right ears respectively of a listener, and the listener's head is immersed in a sound wave having the same sound and arriving at the head at the same time as the arrival of the sound at the ears. The left and right ear versions may be reproduced by loud-speakers or may be communicated to the listener by head phones, one or more loud-speakers being used to produce the wave that reaches the human head, or a single ear phone and one loudspeaker may be used. As shown in Fig. 1, the sounds from sources 10, 11, 12 are picked up by microphones 14, 15 in the dummy head 16 and are transmitted over channels 20, 21 and loud-speakers 22, 23 to listeners A and B. Amplifiers, radio apparatus or the like may be interposed in the circuit as shown at 19. In the arrangement illustrated in Fig. 3, the righthand effect is communicated through the ear piece 35 whilst the left-hand effect and the external locus effect are produced by loudspeaker 36. A delay network 43 is provided in the channel 41, 42 to ensure that the sounds reaching the two ears are correctly phased, whilst an amplifier 45 is fitted in channel 40 to give similar strengths of signal. Fig. 4 illustrates a system in which both ears receive the sound through head phones whilst the head receives the sound via loud-speakers 50, 51. Specification 302,179, [Class 40 (iv), Telephones &c.], is referred to.

Title: Preselective apparatus for gear changing
Filed: 1936-04-08
Abstract: 455,342. Controlling variable speed gearing ; Bowden selector mechanism. CHASSERIEAU, G., 54, Rue du Grand Hospice, Brussels. April 8, 1936, No. 10344. Convention date, Oct. 9, 1935. [Classes 80 (ii) and 80 (iii)] In control mechanism for change-speed gearing, preselection is effected by pulling four Bowden cables 44, 45, 46, 47, Fig. 4, selectively, the executive action being effected by one or other of two suction pistons 4, 4<1>, Fig. 1A, energized by depressing an engine clutch pedal (not shown). The pistons 4, 4<1> which slide in two cylinders 2, 2<1> in line have piston rods 6, 6<1> side by side each with a slot 7 or 71 through which passes a pin 9 carried by a forked striking lever 14. The lever 14 which rocks and slides on a fixed pivot pin 11, is normally held by a spring 15, Fig. 2, at right, in engagement with a selector bar 8. The bar 8 is moved in the two directions of Fig. 1A, by operating valve rods 26, 26<1> selectively. This is done by pulling the cables 45, 46, Fig. 4, selectively which rock valve control levers 22, 221 selectively without rocking a lever 17 which changes the engagement of the striker lever 14 with the bars 8, 81. Thus to bring in second speed, the cable 46 is pulled which rocks the lever 22<1> anticlockwise of Fig. 2, which thrusts the valve rod 26<1> left so as to close a valve 271, Fig. 3, which like its companion valve 27 is normally open. By depressing the main clutch pedal, a main suction valve (not shown) is opened which connects a duct 32 to engine suction. This suction is passed into the cylinder 2<1> so that the piston 4<1>, Fig. 1A, is sucked right pulling the pin 9 over with it so that the bar 8 is thrown over left. The bar 8 is thrown right to the position illustrated by pulling cable 45 which rocks the lever 22 so as to close the valve 27 without sliding the lever 14. Other two ratios are effected by sliding the bar 81, Fig. 2, and this is done by pulling the cables 44, 47, Fig. 4, selectively, which in addition to rocking the valve levers 22, 22<1>, also rock the lever 17 clockwise of Fig. 2, to thrust the striking lever 14 over into engagement with the bar 8<1>. Each of the valve levers 22, 22<1> has an arm 38, 38<1>, Fig. 4, which when a power stroke is to be effected presses down on a lever end 39, Fig. 2, so as to raise a weighted stop lever 42, Fig. 1A. When this stop 42 is not raised, it is engaged by horns 43, 431 on the piston rods 6, 6<1> so that the striker lever 14 is stopped in neutral. The idle loose ends of the four cables 44, 45, 46, 47 are shown in Fig. 8B. If it is desired to pull the cable 47, a manual bolt 50 is slid so as to bring a cam 51 upon it between two spring pistons 52 in the plane of that cable. The bolt is then turned anticlockwise of Fig. 8A, so as to thrust the loose end of the cable 47 right and pull down on the left the operative part of the cable which passes over the bolt 50 and upwards and on to the valve levers.

Title: Improvements in or relating to direct current thermionic valve amplifiers
IPC: H03F3/36
Filed: 1953-04-16
Abstract: 732,290. Valve amplifying circuits. TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE. April 16, 1953 [May 24, 1952], No. 10476/53. Class 40 (6). In a direct-coupled amplifier compensation for variations in the D.C. operating voltages is obtained by applying to an early stage in the amplifier a compensating voltage such that for zero signal input the amplifier output voltage is also zero. The compensating voltage is dependent upon the D.C. operating voltages and varies in the same sense and proportion. As applied to an amplifier comprising stages 1, 2 and 3, 4 fed from H.T. sources 9, 11 respectively and with a source of bias 10, in which the sources 9, 10, 11 are all obtained from the same mains supply and linearly related to one another a compensating voltage is applied at terminals 13 in series with the input 5, 6. If the output voltage is required to be other than zero when the signal input is zero, a stabilized bias voltage giving the required output zeroshift may. be introduced at some point in the amplifier, for example by means of a stabilized source 14 in series with the input.

Title: Improvements in pivotal fin assemblies for rocket propelled projectiles
IPC: F42B10/14
Filed: 1959-03-26
Abstract: 903,842. Tin assemblies for rotated projectiles. BOMBRINI PARODI-DELFINO S.p.A. March 26, 1959 [April 4, 1958 (2)], No. 10537/59. Classes 9 (1) and 9 (2). A collapsible tail assembly for rotated rocket projectiles is mounted by means of ball bearings around the nozzle, so that the rotation of the projectile is not communicated to. the tail during flight. The divergent part 16 of the nozzle is screwed on to the convergent part 18 and has external seatings for ball races 1, 2 carrying a sleeve 3. Slidably secured within the ring 3 by rotatable studs 5 is a bush 7, wings 6 being secured by swaging to the outer ends of the studs. Each wing 6 is partly housed in a milled slot in the ring 3, Fig. 2, and is engaged by a pivot-pin 10. Longitudinal slots 11 guide the studs 5 as the wings move to the extended position. A ring 12 holds the ring 3 in place. A plugged hole 15 is provided for the insertion of the ballbearings 2. On launching the rocket from a tube, the propellent gases issuing from the nozzle impinge on inclined vanes 14 and thus cause the rocket to rotate. Due to inertia, the bush 7 moves counter to the rocket's rotation and in consequence as it slides rearwardly, the studs 5 cause the wings 6 to rotate about the pins 10 to the extended position in which they impinge on the bottom of the slots 8.
