Title: Improvements in or relating to teleprinters
IPC: H04L13/18
Filed: 1965-11-03
Abstract: 1,129,805. Typewriters. OKI ELECTRIC INDUSTRY CO. Ltd. 3 Nov., 1965 [11 Dec., 1964], No. 46570/65. Heading B6F. A teleprinter having a selectably rotatable type-drum 19 provided with plurality of groups of type 19a, 19b, 19c, e.g. different fonts or cases, is shifted to print with the desired group by a mechanism comprising a shaft 14a having a plurality of arms 15, 16, 17, a plurality of selecting forks 10a, 10b, 10c which when actuated rotate the shaft 14a to move the type-drum 19, and a releasable locking slide 111 to lock the shaft in the shifted position. When one of the forks 10a, 10b, 10c is moved to the right, Fig. 1, -the associated fork is rotated and its hub accommodated in the slot 18a, 18b or 18c. Actuation of the fork is initiated by one of three electromagnets 1a 1b, 1c releasing a selecting pawl 3a, 3b, 3c so that when a power cam 5 is rotated, a pulling bar 4 moves one of the levers 8a, 8b, 8c to shift the appropriate fork 10a, 10b, 10c. Character selection.-A rotative movement, adding or subtracting to the shaft rotation is effected by a rack 27 and differential gearing 23, 24, 25. A selecting mechanism also moves the drum 19 axially. Effecting impression.-Printing is effected by projecting the selected type radially outwards against a spring located within the type-drum. Special platen rotation.-The mechanism could be used to effect special rotation of a platen.

[Also in Divisions G4 and H1] . In a pulse delay arrangement, the pulses Ust to be delayed are applied to a Gunn effect element Pr biased by a D.C. voltage source U so as to raise the field strength in the element to at least the critical value or decrease it below said value to initiate or interrupt (as the case may be) the oscillations in the element, thereby producing, as output from the arrangement, current or voltage jumps which are delayed by the amount of the transit time of the high field zones in the element. The pulses are preferably applied to an intermediate control electrode St which extends parallel to the direction of movement of the charge carriers and is separated from the element by a thin insulating layer D. Alternatively, the control electrode forms a P-N junction with the element and is constructed as a point-contact or by applying a P-type layer to the element. Additional intermediate electrodes may be provided on opposite sides of the element or at different distances from the ends. The element is preferably of III-V semi-conductor material. Various circuits employing the arrangement are described, the output being applied either to the same element, thereby constituting a single- or multi-bit store, or to a second similar element, thereby enabling a second delay stage to be included. A plurality of elements may be arranged in cascade, the output from a later element being fed back to the first if desired. The delay obtainable may be adjusted by varying the temperature of the element.

Title: Noise Metering Circuit

Abstract: 1,180,253. Noise measurement. BURROUGHS CORP. Oct.30, 1967 [Oct.31, 1966], No. 49250/67. Heading G1U. A noise measuring circuit for measuring radar receiver noise passed by a quantiser incorporates a differential amplifier-meter arrangement 26-27 whose inputs are supplied respectively from an integrator system 11 which receives the noise output from the quantiser and a potentiometer arrangement 25 which is adjustable to balance the integrator output, balance being indicated by the meter 27 and the potentiometer setting indicating the noise level. The circuit is operated in such a way that input to the integrator system is inhibited during clutter times and dead times of the radar receiver and during these inhibit times the voltage across the potentiometer is controlled by activating the switching and integrating circuit 32, so that the voltage at the potentiometer wiper 28 falls in correspondence with that from the integrator system 11. Activation of the circuit 32 is achieved by applying a pulse to the base of transistor 29 at the same time as the integrator is inhibited. Thus the meter still indicates a balance condition during the inhibit times, and it does not appear that the potentiometer should be adjusted. The integrator system and potentiometer circuit are supplied by the potential across a zener diode 22 connected via resistor 21 to a positive supply. The system 11 integrates by means of RC network 18, 19 in the collector circuit of input transistor 12. The network 13-17 in the transistor emitter circuit biases the transistor so that it responds to input valves only in excess of a given level.

Each pawl 10, 11 is connected via an arm 18, 17 to a push rod 20, 19, the two push rods having slots 20a, 19a through aligned portions of which a pin 21 passes, the pin being fixed to an arm 22 rigidly connected to a spindle 23 rotatable by a hand lever 24 such that rotation of the hand lever 24 in the clockwise direction, pushes rod 19 to the right and through the engagement of the arm 17 with pawl 11 causes disengagement of the pawl 11 and sector 7 thereby allowing the spindle 5 to rotate with lifting of the rear edge of the seat portion through arms 28. On release of lever 24 the push rod moves to the left under action of a spring 25 connected between the two push rods. To lift the front edge of the seat the lever is turned anti-clockwise. Inadvertent disengagement of the pawl and toothed sector are prevented by the engagement of a projection on the arm 17 with an edge formed in a plate 13 on which the pawl is pivotally mounted.
