Title: Dry copy means and methods
IPC: G03B27/30
Filed: 1965-06-18
Abstract: 1,100,676. Thermal copying apparatus. VIEWLEX Inc. June 18, 1965 [Dec. 8, 1964], No. 25849/65. Heading G2A. In a thermal copying machine, the original and copy sheets are passed together between rollers 8 and 9. Roller 8 is a glass cylinder within which is adjustably housed a heat lamp 6 and reflector 7, so that the heat is concentrated on the line of contact between the rollers. The sheets are fed in through slot 3, passing between guides 17, 18, between the rollers, and between further guides 24, 25 to the exit 4. Thus the sheets take an S- shaped path through the machine, which minimizes overall slippage between the sheets. As they enter slot 3, the leading edge engages a projection 20a of a feeler 20, pivoting it clockwise about a shaft 20', and so closing a switch (21, Fig. 6, not shown) to energize the lamp. The sheets also engage another projection 20b of the same feeler, so that the lamp remains energized until the trailing end leaves projection 20b. A thermostat switch keeps the motor which drives the rollers running after the main switch has been turned off until the lamp has cooled sufficiently not to cause any damage to stationary rollers. Similarly the rollers are arranged to idle when the machine is on but has no sheets in it. The speed at which the sheets pass through the machine can be manually set, and then automatically adjusted by suitable circuits to compensate for fluctuations in the lamp temperature. A blower 30 for cooling is provided. If the rollers become jammed, an automatic switch arrangement shuts off the lamp.

Title: Improvements in and relating to the reduction of interference in electric signal transmission systems
IPC: H03G11/00
Filed: 1935-11-08
Abstract: 470,140. Wireless receiving systems. PERCIVAL, W. S. Nov. 8, 1935, Nos. 25997/36 (divided out of 467,263), and 10595/36. [Class 40 (v)] In a circuit for removing interference from received signals to produce "gaps" therein, means are provided for reducing the loss of signal energy due to the gapping. The interference removing circuit is described in Specification 467,263, and comprises a main signal channel which is disabled during disturbances by an auxiliary channel which produces the gapping impulses from the disturbances. The signal preceding the gap may be made to persist in a tuned circuit F, Fig. 6, connected to the output of the main channel and normally damped by a resistance M in series with a conducting diode K. When a gapping impulse is applied to the signal channel, it is also applied to the diode K to render it non- conducting, thus removing the damping from the circuit F which continues to sustain oscillations at the amplitude of the preceding signal to be fed to the output circuit H1, H2. In a further embodiment, particularly for television reception a bias corresponding to " grey " may be impressed on the main channel simultaneously with the removal of the received signal and interference, for instance by a mechanical or thermionic switching device. The gaps may be arranged to be followed by an increase in gain of the signal channel to compensate for loss of signal energy. This is accomplished by an amplifying stage comprising two parallel-connected valves V11, V12, Fig. 7, the valve V12 normally being biassed to cut-off. The gapping impulses are applied to the valve V12 through a delay network E1 and choke L13 so that for a period equal to the gap and immediately following it the amplification of the stage is doubled by the removal of the cut-off bias from valve V12. The increase in amplification may be made to precede the gap by suitable delay circuits and may alternatively be produced by switching over to an alternative valve of higher amplification. Specifications 446,663, 462,228, and 468,994, also are referred to.
