Title: Combining multiple images to enhance dynamic range
Inventor: CHEN HAI
IPC: G06T5/40
Filed: 2009-06-03
Abstract: A method and a system for fusing images in an image processing field are described. The method includes: capturing at least two frames of images having different intensities under different exposure time in the same scene; fusing the images having different intensity values according to an intensity mapping relation between every two frames of images in the images having different intensity values, and obtaining a fused image is, in which the intensity mapping relation represents a corresponding relation between an intensity value of pixel location in a bright image and that at the corresponding location in a dark image. Through the method and the system for fusing the images the dynamic range of the image is enhanced. Statistical analysis of intensity mapping histograms, pixel weighting and bilateral filtering may also be used.

Abstract: A quench path outlet assembly or method for a cryogen egress path 40 from a cryogenic vessel comprises a quench valve 26, a cryogen egress tube 32 and a burst disc closing the egress path 40. The quench valve 26 may be located within a flange 28 which may be split into two parts at a joint 44 such that the valve 26 can be separated from the burst disc element when the disc element needs to be replaced. The burst disc may be located at a position 34 upstream or downstream of the valve 26. The flange 28 and egress tube 32 may be tested to ensure that they are leak-free prior to being fastened and sealed to a cryogenic vessel of a superconducting magnet. The valve 26 may be removed to provide a more compact vessel for transportation. The valve 26 and straight tube 32 may provide a compact, efficient, reliable cryogen egress arrangement which cause less back pressure and in which the valve 26 may open directly to the atmosphere. The assembly or method may be used in magnetic resonance devices.

Title: Improvements in joining sheet metal structures
IPC: E04B2/62
Filed: 1961-03-21
Abstract: 902,993. Making posts; sheet-metal joints; bending cutters. EXPANDED METAL CO. Ltd. March 21, 1961 [April 12, 1960], No. 10303/61. Classes 83 (2) and 83 (4). [Also in Group X] A method of joining together two sheet-metal members comprises placing a flat portion of one member back-to-back with a flat portion of the other member, cutting through the two contiguous flat portions at two places to form two spaced pairs of tabs, each pair consisting of two identical overlapping tabs, one of which is integral with one member and the other of which is integral with the other member, bending both pairs of tabs out of the planes of the flat portions in opposite directions towards the same side of the flat portions through 180 degrees, pressing the bent tabs and the flat portions together and forming a concave depression in them which extends across the bent edge of each tab. In an embodiment the central web sections 18 and 19 of a partitioning stud 15 are joined together at a number of places 22 by the method of the invention. Apparatus for carrying out the method comprises a punch and die assembly 44, Fig. 2. The web sections to be joined are supported on a die block 46 which co-operates with a U-shaped bending cutter 48 having cutting edges about the truncated conical surfaces 51, 52 of the limbs 49, 50. The bending cutter cuts two spaced double-thickness D-shaped tabs 56 and 57, Fig. 4, from the overlapping web sections and curls them inwardly toward one another on the under-side of the web as they are being cut. At the end of the curling operation a lower die 47 is raised to engage the tabs and co-operates with the bending cutter to compress the tabs against the webs and to impart a concave depression in the joint, Fig. 9, which prohibits the tabs from being lifted or bent outwardly when subjected to structural forces.

IPC: F02B75/26
Filed: 1921-02-11
Abstract: 180,278. Almen, J. O. Feb. 11, 1921. Rotary distributors.-In an internal-combustion engine having the cylinders arranged around and parallel to the crank-shaft, and rotary valves at the heads of the cylinders, the valves are fitted with ignition plugs and with electric contact members arranged to engage a fixed contact ring while the plugs are in registration with the cylinder ports. Fig. 1 shows an engine having two sets of seven cylinders 3 arranged around the crankshaft 8, the valves 25 being arranged one at each - end of the engine and formed with inlet passages :38, Fig. 4, and exhaust ports 39. Three sparkplugs 50, Fig. 4, are provided in radial pockets 51 in the valve, holes 52 in the pockets communicating with the cylinder ports 21 at the times of firing. To prevent pocketing of burned gases in the chambers 51 after an explosion, discharge ports 60, Fig. 5, are provided so as to communicate with the exhaust ports after ignition. One terminal of each spark-plug 50 is grounded through the engine frame, and the other extends from the inner end of the plug so as to engage yielding legs 53 of contact plates 54, Fig. 9, equally spaced around insulating-rings 56 secured within the rotary valve 25. The contact plates 54 are further formed with prongs 57 which engage, at the required time for firing the seven cylinders, with conducting-rings 58 secured in the, cylinders heads concentric with the crank-shaft. This engagement between the prongs 57 and rings. 58 is effected by the movement of the valves 25 due to their eccentric mounting and the valve-gear described below, so that firing occurs in the order a, c, e, g, b, d, f, Fig. 4. The valves 25 are bolted to pinions 28 which are mounted on eccentric journals 30 on the crank-shaft and engageinternally-toothed gears 31 fixed to the cylindercasings. The gears 28, 31 are such that the valves are rotated at one-sixth crank-shaft speed and in the opposite direction; the valves also receive a wobbling motion due to their eccentric mounting.

Abstract: 1,247,797. Linkwork; bearings. TRANSISTOR AUTOMATION CORP. 27 Feb., 1969, No. 10557/69. Headings F2A and F2K. [Also in Division H2] A vacuum chuck 28 (Fig. 3) for holding an article 18 being worked on or tested in an automatic probing machine of the type described in Specification 1,128,034 (see Divisions G3 and H2) is raised and lowered by a wedge 44 movable horizontally by a solenoid 64, the wedge acting on the base of a plate 50 carrying the chuck 28. An annular diaphragm 58 secured to the plate 50 and to the rim of a cylindrical cavity 34 formed in a base 30 limits the plate 50 to vertical movement. Annular ball bearings 42, 54 having flat cages 40, 52 of a phenolic resin separate the wedge 44 from the plate 50 and a guide plate 38. A dashpot 72 is connected to the wedge. Energization of the solenoid 64 moves the wedge rightwards against the thrust of a compression spring 70, a spring- loaded stud 48 pulling the plate 50 downwardly on to the wedge 44. The base 30 is mounted on a table indexable in two directions at right angles under automatic control. The wedge device serves to raise the article 18 into contact with a probe 104 of a manipulator (Fig. 4). A holder 112 for the probe 104 is supported by parallel leaf springs 106, 108 from a bifurcated block 76 slidable relative to a support 80 by a joystick 86. The halves of a split ball 88 on the joystick are spring-urged apart to engage recesses 90, 92 in the support 80 and a plate 82 to which the block 76 is bolted. The holder 112 is adjustably spring-loaded downwards by a curved spring 130 acting via a leaf spring 128, a lug 120 on the holder being movable between shoulders 124, 126 which limit vertical movement. A screw 134 acting between two portions of the block 76 allows vertical adjustment of the probe 104. A strain gauge 142 on the leaf spring 106 is used to provide a signal indicating whether the probe 104 has engaged the article 18 when the latter is raised. If it has not, the table is automatically indexed until contact takes place. No supply to the probe via a lead 146 is permitted until such contact is made.

Abstract: 768,508. Colour television. HAZELTINE CORPORATION. April 13, 1955 [May 10, 1954], No. 10630/55. Class 40 (3). [Also in Group XL (c)] The synchronizing burst at colour sub-carrier frequency occurring during the line retrace interval is separated from the colour sub-carrier appearing at the output of the chrominance channel 19 in a colour television receiver by means of a normally non-conducting triode 43 which receives the combined signal across its tuned cathode load 55 and is gated to conduction during the line retrace interval by a positive pulse applied to its grid from the line scan generator 25. The synchronizing burst is developed in amplified form across anode tuned circuit 45, whilst the low grid-cathode impedance of the conducting triode effectively damps the cathode circuit and prevents the burst entering the chrominance detector 21. The synchronizing burst is applied to control the sub-carrier generator 22 through an amplifier stage 23 which may also be gated by pulses from the line scan generator so as to permit a greater amplification to be obtained from a valvo of given power rating.
