Title: Recording and reproducing colour picture information
IPC: H04N9/077
Filed: 1971-12-23
Abstract: 1369839 Recording colour television signals SONY CORP 23 Dec 1971 [28 Dec 1970] 60187/71 Heading H4F  An arrangement for recording colour television signals on monochrome film comprises, as shown, modulators 23B and 23R for modulating the colour-difference signals R-Y, B-Y on to a carrier derived from the horizontal synch. signal S h  by frequency multiplication and (in the case of 23R) a #/2 phase shift, adding at 22 the luminance signal Ey, and also the chrominance carrier E j  with a phase which is charged with respect to the chrominance signal in successive fields. This phase reversed is obtained in the arrangement shown by the switching of 30 by vertical sync. signals to successively open gates 27 and 29, and a discrimination signal Ed identifying alternate fields is obtained from gate 35 during vertical blanking periods (signal S l ), the signal having a frequency of about 100 KHz and being obtained from S h  by a second frequency multiplier 33. The composite signal is applied to an electron beam recorder 37 the electron beam of which is scanned across monochrome film 21 as the film is continuously advanced. For reproduction from the film (Fig. 4, not shown) two frames are scanned simultaneously and the outputs added and subtracted (after extraction of the luminance signal by filtering out the low-frequency components) to produce the chrominance and index signals, the discrimination signal controlling the appropriate switching. Figure 5 (not shown) illustrates the use of a colour camera using a stripe filter to produce a colour-separated image, in which the phase-reversed index signals are obtained by illuminating the photosensitive layer through the filter during vertical blanking periods alternately with green and cyan light, and a peripheral area of the colour filter may be used to provide the discrimination signal. Phaseinversion in successive fields may be effected to the chrominance carrier instead of the index signal. By using a colour camera as described in Specification 1,328,411 the index signals may be obtained from the camera output by supplying appropriate electrical signals to the index electrodes of the camera, separating the chrominance and index signals by use of a one-line delay and adder and subtractor, and switching at line frequency to obtain an index signal of constant phase for the frame (Fig. 10, not shown).

Abstract: 1,196,200. Photographic vesicular images. AGFA - GEVAERT A. G. Dec.20, 1968 [Dec. 23, 1967], No. 60699/68. Heading G2C. The invention comprises photgraphic images consisting of a silver image and vesicles superimposed imagewise on the silver image and a process for the production of such photgraphic images which comprises (a) imagewise exposure of a supported light-sensitive silver salt emulsion layer and developing the exposed layer to form a silver image in the layer; (b) treating the layer containing the silver image with a compound which is decomposed by the silver image to from a gas or a product which becomes gaseous on heating the layer and (c) heating the layer to form vesicles superimposed imagewise on the silver image. The compound used in step (b) may be hydrogen peroxide, and this step may be carried out with H 2 O 2  vapour follwed by water vapour at 50-90 C; the water vapour may have a pH between 8 and 12, which is achieved by adding to the water vapour small amounts of water vapour or volatile amines. This invention provides a greater density of the silver images produced in the photgraphic silver salt layers by the superimposition of the vasicular image.

Abstract: In a method of and apparatus for processing PAL colour television signals in digital form, the signals are transcoded between (i) a 2fsc format consisting of an encoded signal of PAL type sampled at 2fsc and (ii) a 3fsc format consisting of a luminance signal Y sampled at 2fsc and a chrominance signal C sampled at fsc and comprising U + V and U - V on alternate lines (or either the luminance signal or composite chrominance signal by itself). Converting from the 2fsc to the 3fsc format, over the chrominance bandwidth (22) undelayed and 1- and 2-line delayed (14, 16) samples are combined in the proportions 1 DIVIDED 4:1 DIVIDED 2:1 DIVIDED 4, and below the chrominance band the 1-line delayed samples are low-pass filtered (24), these together providing the luminance signal Y. To provide the chrominance signal C the undelayed and 2-line delayed signals are combined (50) in the proportions - 1 DIVIDED 4:1 DIVIDED 4. The low- and band-pass filters (24, 22, 52) are digital transversal filters operating on adjacent samples in the signal. Transcoding in the other direction is similar. <IMAGE>

Title: A water displacing device for use in explosive welding underwater
IPC: B23K20/26
Filed: 1979-07-16
Abstract: When explosively welding an underwater pipe 13 to a surrounding flange 14 the presence of water in the pipe in the region of the explosive charge may cause rupture of the pipe adjacent the flange. To avoid this rupture, water is displaced from this region by introducing into the pipe a device comprising a folded bag 21. As described, the bag is interposed between an explosive charge 51 and a moveable carriage 17. Prior to detonating the charge, gas is introduced into the bag to cause it to become unfolded. The carriage 17 is moved along the pipe by the bag as the bag unfolds and inflates and displaces the water away from the explosive charge. In an alternative embodiment where the water cannot be displaced away from the charge, the bag is made in a tapered form and its inflation displaces the water past the charge. <IMAGE>

Title: Controlling filter cleaning
IPC: B01D46/04
Filed: 1981-05-12
Abstract: Dirt etc collecting in a pressure sensor tube (22) of a filter element cleaner control system is flushed out periodically. The filters (14) are cleaned by a backflow pulse of compressed air from nozzles (19) when a preset pressure differential is reached in chambers (11, 12) as monitored at tappings (22, 23). Typically one fifth of the filters (14) are cleaned by a sequence of 0.06-0.2 second backflow pulses of compressed air each time the preset pressure differential is reached. When all the filters have been cleaned, the pressure sensor tube (22) is also cleaned by a backflow of air. The backflow pulse control system comprises a pressure transducer and microprocessor (Figs. 2 and 3) and during cleaning the pressure signal from the transducer is suppressed for 1-2.5 seconds. If the backflow pulse of compressed air does not reduce the pressure differential below the preset differential after 90 seconds, an audible and visual warning signal is produced. The preset pressure differential and actual pressures in the chambers (11, 12), backflow pulse time and number of cleaning cycle pulses may be visually displayed and printed. <IMAGE>
