Patent GB-377637-A (GB)
Title: Improvements relating to the manufacture of sheet glass by rolling
IPC: C03B13/16
Filed: 1932-05-20
Abstract: 377,637. Rolling sheet glass. SOC. ANON. DES MANUFACTURES DES GLACES ET PRODUITS CHIMIQUES DE ST. GOBAIN, CHAUNY, ET CIREY, 1 bis, Place des Saussaies, Paris. May 20, 1932. No. 14414. Convention date, May 23, 1931,. Addition to 361,839. [Class 56.] Relates to the method of rolling sheet glass, described in the parent Specification, in which that part of a roller which first comes into contact with the hot glass is given an initial warp or distortion by cooling an interior zone of the roller at the point where contact occurs. According to the present invention, the cooling is effected by directing liquid into the zone to be cooled, not only during periods when the roll is at rest but also while the roll is rotating. This localized action of the cooling-liquid can be combined with a circulation of liquid through the roller in the ordinary manner. The cooling-liquid is led into the roller A by two conduits G, H and it is discharged through a conduit J. The liquid entering through the conduit H serves for cooling the roller generally, and it flows into the interior of the roller around a pipe E arranged coaxially within the roller. The liquid then passes through passages L and is discharged through passages M and the conduit J. The liquid which enters the conduit G passes through the pipe E which terminates at about the middle of the roller and has its end curved towards that part of the wall of the roller which is to be cooled the most. The pipe rotates with the roller and the localized cooling continues during the rolling operation.

Abstract: 1,014,853. Resistors. PLESSEY CO. Ltd. April 12, 1962 [April 21, 1961], No. 14445/61. Heading H1S. A metal film resistor is protected by wrapping a foil or strip of plastic material round the resistor the plastic being coated with an adhesive so that it adheres tightly to the metal film and the body on which the film is deposited. Fig. 1 shows a ceramic body 1 on which is deposited a metal film 2 in which is ground a helical groove 3 which lengthens the resistive path. Terminal wires 4 and 5 are soldered to the ends of the body to contact the metal film and the metal film protected by winding a polyester tape provided with a self-adhesive rubber coating tightly around the body. When slightly more than one complete turn has been applied a length of aluminium foil, 7, slightly longer than is required for one complete turn, in interposed between the first layer of tape, 6, and a layer 8 applied over the metal foil. The winding is continued preferably for one complete turn after the end of the metal foil so that the tape will not unroll when it is severed from the supply. The ends of the resistor are finally sealed by pouring or pasting on plugs 10 of polyester resin. Before wrapping on the plastic tape the resistor may be coated with silicone varnish. Apparatus for applying the tape, comprising three rollers spaced equally around the circumference of the resistor and applying pressure to force the tape into close contact with the resistor, is also described, Fig. 2 (not shown).

Title: Image reproduction system
IPC: H04N5/84
Filed: 1973-03-26
Abstract: 1395472 Film scanning MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 26 March 1973 [25 March 1972 (2) 14 July 1972 (2)] 14481/73 Heading H4F Colour television signals recorded on a film are read-out using a flying spot scanner and associated photo-cells to produce, on an associated display, either movie pictures if the film is fed continuously, or still picture if the film is stopped, an auxiliary motor being included to move the film, after the main drive has been disengaged to allow for still picture reproduction, to ensure registration of the scanning raster and a film frame. The auxiliary motor is stopped by detection of a sync mark on the film by a photo-electric converter co-operating with an associated light source. The scanning raster for scanning the moving film has a height equal to twice the height of a film frame and is controlled by a vertical sync signal derived by detecting, with a sync detector, vertical sync marks provided on the film, one sync mark being provided for each film frame. For reproducing a still picture, the main film drive is disengaged, and the auxiliary motor may be energized until one of the vertical sync marks is detected by the sync detector, the scanning raster also being collapsed to be the same height as a film frame, and the scanning raster then being moved by half the height of a film frame, so as to be in register with the film frame. Alternatively, as shown in Fig. 7, a second sync detector 51 may be provided for still operation in which case the collapsed raster need not be moved. The sync detector 31 for movie operation may then be omitted if the output of detector 51 for movie operation is delayed by half a television field to provide a movie sync signal equivalent to that detected by detector 31. To provide for automatic detection of still frames, the movie frames preceding a still frame may be provided with additional sync marks, each provided midway between two vertical sync marks, two detectors arranged as in Fig. 7 being used to detect this arrangement. Still film frames may be of twice the height of the movie film frames, so that the scanning raster need not be collapsed when viewing these still frames. These still frames may be provided with positioning sync marks spaced from the centre of each still frame by one half the height of a movie frame. A manual switch may be provided to allow for repeated still operation, operation of the switch momentarily cutting off the "stop" signal to the auxiliary motor, which then feeds the film until the following sync mark is detected.
