Title: Improvements in apparatus for making sheet glass
IPC: C03B13/04
Filed: 1925-03-21
Abstract: 240,074. White, A. E., (Pittsburgh Plate Glass Co.). March 21, 1925. Rolling.-Relates to a machine for making sheet glass continuously from a tank by rolling, as described in Specification 192,092, and consists in providing (1) means for enabling the slot member of the tank to be removed readily or adjusted vertically. (2) means for preventing the introduction of bubbles into the sheet, and (3) means for preventing cracking and for ensuring flatness of the edges of the sheet. Mounting the slot member. The machine comprises a forehearth 1 projecting from a tank furnace and provided with a gate 2 and a slot member 3, sheet-forming rolls 5. 6, situated close to the slot 4 in the member 3, and a lehr 13 in which the sheet 11 is flattened and annealed. The slot member 3 consists of a fireclay block mounted in a frame consisting of channel members 19, 20 in which the block is clamped by means of bolts 19<a>, Fig. 3. The frame is suspended by hangers 21 from a crane, and may be adjusted vertically or may be replaced readily after the gate 2 has been dropped to stop the flow of metal. Preventing bubbles in the sheet. The slot 4 is provided with lips 22, 23 of " calite " or other heat resisting metal, the temperature of which can be regulated. Usually these lips are cooled by means of perforated air pipes 26 or by means of water circulators, and their use is stated to eliminate the bubbles which are sometimes introduced into the sheet when the glass passes directly from the clay block to the rolls 5, 6. Instead of using the metal lips, the object may be accomplished bv chilling the glass, particularly the under surface. For this purpose, water-cooled or air-cooled pipes may be arranged in contact with the glass as it emerges from the slot. In another construction, the slot is formed with lips, and perforated air pipes are arranged to direct jets of air into the space between the lips and the roll 5, 6. In a further construction, the slot is formed with an upper lip, the lower lip being an attached metal member similar to the member 22. In some cases, the metal lips may require to be heated instead of being cooled in order to prevent excessive chilling of the glass. Forming and flattening the edges of the sheet. The triangular spaces formed between the rolls at the ends of the slot 4 are closed bv hollow metal members 27, Figs. 3 and 6, which are heated internally by means of burners. The members are not in contact with the rollers and their inner edges 33<a> are truncated. The use of these heated members is stated to prevent firecracks in the edges of the sheet. The sheet after it emerges from the rolls 5, 6, passes over rolls 9, 10 into the lehr, and its edges tend to turn upwards slightly. To overcome the tendency, the edges are flattened by rolls 12 which bear against the rolls 10. The roll 12 at each side of the sheet is carried by a lever 36 provided with a counterweight 37 to regulate the pressure of the roll.

Title: Improvements in noise limiting circuits for radio receivers
IPC: H03G3/26
Filed: 1955-03-17
Abstract: 774,440. Radio receiving circuits. COLLINS RADIO CO. March 17, 1955 [April 12, 1954], No. 7844/55. Class 40(5) The muting circuit of an asm. receiver is made operative not only in the absence of carrier, but also if the signal-noise ratio exceeds a predetermined value, the noise being detected by its very high modulation ratio. The muting valve 41, when conducting, reduces the grid bias of the audio output valve 26 below cut-off, but in the presence of a carrier valve 41 is normally non-conducting due to a negative bias tapped off the load resistor of the detector 14 at point 48 and applied via a low-pass filter 51. Hence if the carrier ceases, the output is muted. A second diode 58 is coupled by a condenser 57 to the same point 48 and produces across its load resistor 55 a voltage proportional to the peak value of any audio-frequency modulation. This voltage opposes the negative bias, and is applied to the muting valve via a second low-pass filter 62, but it cannot exceed the negative bias with a normally modulated carrier and hence the receiver is normally operative. The presence of noise however, having a peak amplitude in excess of the carrier level, causes the voltage at 55 to exceed that at 48, and so allow valve 41 to conduct and mute the output.
