Title: Improvements in or relating to the manufacture of plate or sheet glass by rolling
IPC: C03B13/02
Filed: 1934-04-13
Abstract: 423,284. Glass manufacture. COMPAGNIE REUNIES DES GLACES ET VERRES SPECIAUX DU NORD DE LA FRANCE, Boussois-sur-Sambre, Nord, France. April 13, 1934, No. 11229. Convention date, May 5, 1933. [Class 56] Relates to the method of making plate or sheet glass in which molten glass is poured from a melting-pot 4 on to the casting table 1 of a rolling-apparatus, or between the rollers of a double-roll machine, and the pot is moved parallel with the axis of the rollers during the pouring-operation. According to the invention, the stream of glass that descends from the pot is seized, as it approaches the end of the roller 2, and is prevented from falling back on to the glass that has been poured. In the construction shown, the lateral spreading of the glass 3 on the table 1 is restricted by side plates 5, 6, the upper part 7 of the plate 6 being inclined away from the table. A blade 8, situated above the part 7, is secured to a plate 9 which is pivoted on an axle 10 and is counterbalanced by a weight 12. During a pouring-operation, at the time when the pot 4 approaches the side plate 6, the stream of glass descending from the pot meets the blade 8 and then continues to fall on to the plate 9. As soon as this takes place, the plate 9 is turned in the direction of the arrow f<2>, either by hand or automatically, and thus prevents the glass on the plate from falling on to the mass 3 on the table. The glass on the plate 9 can be drawn back into the pot.

An electrode assembly comprises a stacked array of planar elements mounted on support pins extending upwards from a base 10, the elements being separated by insulating washers, some elements having at their ends elongated openings which fit round the pins. The sup; port pins 18 are attached to base wires 14 through sleeves 16. Beads 20 on the pins serve to locate the anode 22 which is the first element assembled ; this is of channel form, with a raised portion 28. Ceramic sleeves 36 are now slipped over the pins, and ceramic washers 38 over these, serving to separate the anode from the grid 40. Similar washers 48 determine the grid-cathode spacing. The cathode 50 comprises two dished plates 52 joined together, enclosing a space for the heater 56. Strengthening channels 58 formed in the cathode' plates also act as ducts through which the heater leads pass, shielding them closely up to their point of attachment to their respective lead-wires. Notches 54 in the cathode plates fit round the ceramic sleeves 36, allowing some free lateral expansion. The assembly is duplicated on the other side of the cathode, to form a doubletriode. The upper ends of pins 18 are finally swaged over to secure the stacked array in position. Each anode 22, 72 is insulated from one or other of pins 18 by respective ceramic bushings 34, 76. Such a structure is suitable for automatic assembly. If desired, the elements may be assembled completely on the pins 18 before the latter are secured to the base 10.

Title: Binary coded information transmission
IPC: H04J3/20
Filed: 1978-03-22
Abstract: In the transmission of PCM information over two-wire lines using resonance transfer, high demands are placed on the coincidence of the switches at the two line ends (LE). These demands are lessened by the procedure presented here. For this purpose, in a first section of the bit time period, a positive or negative charge, corresponding to the binary value to be transmitted, is applied to the two-wire line (ZLA) at each line end (LE). In a following section of the bit time period, the charge state is tested at each line end (LE), and the received bit value is determined by comparison with the charge applied at the same end. The method is preferably used in PCM time-division multiplexed transmission systems. <IMAGE>
