Title: Improvements in or relating to oscillation generators
IPC: H03B5/10
Filed: 1936-10-27
Abstract: 483,918. Valve generating circuits. STANDARD TELEPHONES & CABLES, Ltd., LAWRENCE, W., and LEVY, M. M. Oct. 27, 1936, No. 29175. [Class 40 (v)] An oscillator is provided with positive or regenerative feed-back at the oscillation frequency and with negative feed-back at all frequencies, the negative feed-back voltages being derived from a resistance in an output circuit whereby the same proportion of each component frequency in the output is fed back negatively. In the case of a dynatron oscillator having an anti-resonant circuit in the plate circuit of the valve for determining the fundamental oscillation frequency, an adjustable voltage derived from a feed-back resistance in the anode circuit of the valve is applied to the grid of the valve in such a phase as to oppose regeneration at all frequencies. The pentode valve V1 is provided with a positive feed-back coupling including a tuned antiresonant circuit C1, L1, the coil L1 being coupled to a coil L2 in the control-grid circuit. Negative feed-back is obtained from a resistance R1, so that the voltage applied to the grid consists of the sum of the voltages across the coil L2, and across the tapped part of the resistance R1, the tapping point being adjusted so that the positive feed-back is nearly neutralized by the negative feed-back. Several amplifier stages may be provided, the anodecathode circuit of the last valve being coupled to the grid-cathode circuit of the first valve as in the single-valve arrangement shown. Positive feed-back may be applied to one grid of an oscillator valve and negative feed-back to a second grid. In such an arrangement, the anode-cathode circuit includes a resistance and a coil in series, the resistance being tapped to supply the negative feed-back at all frequencies to one grid, and the coil being coupled to a tuned circuit to provide positive feedback at a particular frequency to the other grid. In a modification, the resistance R1 is connected in series with the tuned circuit and may be in series or in shunt to the output impedance, or alternatively negative feedback is obtained from a resistance in the common cathode lead providing grid bias for the valve, a byepassing condenser being connected across an adjustable portion of the resistance.

Title: Reproducing apparatus for continuously moving documents
IPC: G03B27/50
Filed: 1963-07-24
Abstract: 1,040,588. Photocopying apparatus. R.A.A.DARTHENAY. July 24, 1963 [July 26,1962] No.29362/63. Heading G2A. In a photocopying apparatus the original and the copy sheet move continuously on either side of a size-reducing optical system, their respective speeds being in the same ratio as their respective distances from the optical system; the two are driven by a single motor, the original being driven by a positive sprocket engagement. In the form shown, the document 5 to be copied is folded accordion-fashion and is supoorted on a ledge 3. It is drawn continuously across a platen 2 by means of pointed caterpillar tracks 11, the latter being driven by a belt 18 from a motor 21. The drive for the caterpillar tracks, and hence the unfolded document 10, is coupled by means of reduction gearing to a countershaft 25, which in turn drives the film transport in a camera 8 having a lens 9. The arrangement is such that the respective speed of movement of film and document is in the same ratio as their respective distances from the lens 9. Thus the image of any point on document 10 remains stationary on the moving film for the duration of the exposure. The light sources 29, 30 are arranged above the platen 2 in an enclosure 31. In the top surface of the enclosure is a transverse slit 37, whose width can be varied by sliding blades 38, 39. After the document strip 10 leaves the apparatus, it can be re-formed into accordion folds, or it can be severed by a photo electrically controlled cutting device. If the motion of strip 10 is arrested accidentally, the light sources and driving means may be automatically shut off, or the camera could be closed by a shutter. If the motion is stopped intentionally, it can be arranged that actual stoppage occurs only when a fold in strip 10 lies below slit 37. More than one photograph may be taken of the document, as a safety precaution, or separate parts of it may be photographed separately.
