Title: Method for blurring the background of an image
Inventor: KIM YOUNG-GEOL
IPC: H04N13/122
Filed: 2009-05-06
Abstract: A digital image processor and a method for blurring a background of an image in a digital image processor is provided. An image is photographed with a flash being on and off when a shutter input signal is received. The background of the image is blurred through comparison between an image prior to the shutter input signal being received and an image during which a flash is activated, and then a subject of the image with a flash being off is combined with the blurred background. A processor blurs an image generated by a brightness difference between a first image generated before a shutter input signal is received and a second image generated with the flash being on after the shutter input signal is received and combining a third image generated by turning off the flash after the shutter input signal, to the blurred image.

Abstract: 706,341. Television. COLUMBIA BROADCASTING SYSTEM, Inc. May 1, 1951 [May 11, 1950], No. 10214/51. Class 40 (3). [Also in Group XL(c)] Means for increasing the sharpness of reproduced television pictures comprises a circuit for differentiating the incoming picture video signal and combining the differentiated and undifferentiated signals whereby the rate of change of signal level during transitions between dark and bright portions of the picture is increased. The picture video signal developed at the anode of valve 26 is applied directly to the control grid of receiving cathode-ray tube 13 and is also passed to a differentiating circuit shown within the broken line rectangle 24. The differentiation is achieved by the inductive anode circuit of valve section 47, the output signal therefrom being amplified by valve section 59 and applied to the cathode of the cathode-ray tube. If desired a further inverting stage may be used to re-invert the differentiated signal before application to the cathode-ray tube. In a modification, Fig. 5 (not shown), the output of the differentiating circuit is applied to two oppositely-poled parallel-connected rectifiers which are so biased that only the positive- and negative-peaks of the differentiated signal are passed. In this arrangement, the differentiated and undifferentiated signal are combined before application to the cathoderay tube. Delay means may also be incorporated into the circuit to enable the relative-phases of the differentiated and undifferentiated signal to be selected to achieve an optimum effect. The invention is not limited to use in receivers but may also be employed at the transmitter.

Abstract: 731,637. Gas turbine plant. SIEMENSSCHUCKERTWERKE AKT.-GES. April 15, 1953 [April 17, 1952], No. 10341/53. Class 110 (3). [Also in Group XXIX] A gas turbine c driving a compressor a for boosting the pressure in a long distance gas main is driven by gas tapped off for low pressure consumption from a main III. The tapped quantity passes through a heat exchanger b supplied by a combustion chamber g fed through an ejector h with gas from the exhaust side of the turbine c and pre-heated air from gas coolers d and e. A conduit p and a cooler f enable gas from the turbine to be re-circulated to the compressor a to compensate for fluctuations in the load on the main III. By means of control systems m, n, o and r, the quantities of air and gas flowing through the ejector h are controlled by the pressures in mains II and III and the intake pressure of the turbine c while the quantity of re-circulated gas is controlled by the intake pressure of the compressor a. To prevent large fluctuations in the heating value of the gas from producing excessively high temperatures in the gas entering the turbine the combustion chamber and the heat exchanger may be combined and a cooler interposed between them. If the' heating value is constantly higher than that required in the main III the tapped gas may be subjected before expansion to an incomplete combustion process to which air is supplied from the cooler d by a second compressor coupled to the turbine c.

Title: Tubular conductor
IPC: H01L39/24
Filed: 1974-03-08
Abstract: 1439442 Making superconductive conductors; drawing SIEMENS AG 8 March 1974 [9 March 1973] 10577/74 Headings B3A and B3P [Also in Division H1] A method of manufacturing seamless tubular conductor comprises depositing a layer of electrolytic Cu 2 on a Nb layer 1 by fusion under a vacuum of 10<SP>-4</SP> mm. Hg and thereafter cold drawing the resulting composite tube to obtain the required external diameter. A Nb tube 1 having, e.g. wall thickness 2 mm., internal diameter 40 mm. and length 500 mm., is mounted inside a thicker walled Cu tube 2 with a wall-thickness, e.g. 20 mm., of the same length. A support tube 3 of V 2 A steel and a support ring 4 of Nb or V-A steel complete the assembly which is introduced into a vacuum chamber 5. A narrow zone of the Cu is melted by the h.f. heating coil 7, which is moved downwardly in the direction of the arrows 8. After cooling the support tube 3 is removed, e.g. by turning. The tube is then applied to a round bar hardened steel mandrel (11), Fig. 2 (not shown), and pulled through a hard metal or steel drawing nozzle (13) as in Fig. 2 (not shown). The wall thickness is reduced by about 10% at each drawing step carried out with successive drawing dies of decreasing internal diameter. Typical drawing speeds are about 5 m./minute and final dimensions of the conductor are 10 m. length with Cu and Nb layers approximately 1 and 0À1 mm. thick. In another method of manufacture, Fig. 3 (not shown), molten copper at a temperature of 1150 C. is poured from a graphite crucible (39) into the annular cylindrical cold mould formed by a Nb tube (32) and a steel tube (33) welded to an end plate 34; the whole operation taking place in an evacuated chamber (31). The wall thicknesses of the Nb and Cu are 1 and 10 mm. respectively. The cold drawing is then carried out as in the first method. Drawing aids such as "Zapon" (Registered Trade Mark) or other quick-drying nitrocellulose lacquer, soapy lubricants such as zinc stearate or drawing oils may be used in both methods. The Nb may also be coated with a layer of Nb pentoxide by anodic oxidization (e.g. in a 25% aqueous ammonia solution) to facilitate drawing. The Cu layer may also be applied to the Nb by centrifugal casting.

Abstract: 1,63,776. Film winding mechanisms. EASTMAN KODAK CO. March 13, 1964 [March 16, 1963], No. 10644/64. Heading G2A. Each frame of a film strip has a corresponding aperture, which is sensed by means which then locks the transport mechanism; the lock is released again when the shutter is operated. In the form shown, the film is transported and the shutter set by lever 13 being turned in the direction of arrow 16. The lever, which is pivoted at 20, has gear teeth 21 which, via a pinion 22, drive a rack 23 to the left against a restoring spring 24. During this movement a lever 26 on the rack engages against and rotates a toothed segment 27, which in turn meshes with a pinion 28, so setting the shutter 30. Lever 13 also carries an off-centre shaft 38 which has an angled pawl 40 engaging the teeth of a ratchet gear 42. Coupled to gear 42 is a further gear 44 which drives, via gear 45, a gear 46 coupled to a shaft 48. Thus as lever 13 turns, the motion is transmitted through the gear train to shaft 48. This shaft drives a member 36 coupled to the film take-up spool (not shown). Thus operation of lever 13 both sets the shutter and transports the film 35. Each frame of the film has an aperture 58, in which a sensing slide finger 57 can engage, as in the "set" position of Fig. 3 (not shown). The shutter release button 14 is mounted on an arm 50. When the button 14 is pressed downwards to trigger the shutter, a lug 54 of the arm 50 engages against the sloping edge of a right-angled ear 55 of a lever 52, causing it to turn against a restoring spring 53. This turning movement withdraws the sensing finger 57 from aperture 58. At the same time a lug 62 engages under a lug 64 on arm 50 (position of Fig. 2) so as to prevent a further depression of trigger button 14. As lever 52 is rotated, it causes, via a coupling shaft 66, a lever 68 to rotate correspondingly, lever 68 being retained by a latch 69. A pawl 70, normally locking a ratchet 71 to prevent operation of the film transport shaft 48, is biased away from ratchet 71 by a spring 72, so that transport may take place when lever 16 is operated. When a complete film has been advanced, sensing finger 57 falls once more into the next aperture 58, so that spring 53 is able to pull levers 52, 68 back into the "rest" position. A pin 74 on rack 23 engages latch 69, and pivots it so as to release lever 68 which, as it retracts to the "rest" position, allows pawl 70 to lock ratchet 71 once more against film transport. Fig 4 (not shown) is a further interlocking arrangement.
