Abstract: 1,237,890. Typewriters. VARITYPER CORP. 7 Nov., 1968 [8 Nov., 1967], No. 52896/68. Heading B6F. Repeat action of a power-operated hammer 18 in a typewriter is prevented by a pawl 70 having a foot 72 which on depression of a character key 19 is released from engagement with a projection 45 of a one-revolution spring clutch 44 through a link 78 pulled leftwardly by depression of the key, the clutch initiating an impression cycle of the hammer 18 by rotation of a cam 47, one function of which comprises the pivoting counterclockwise of a lever 53 by a pin 66 on the cam engaging a cam follower end 86 of the lever 53, such pivotal motion of the lever 53 causing a cam end 85 thereof to engage the link 78 and push the link downwardly in an L-shaped slot in the pawl 70 so that the pawl is released from the force of the link 78 and can return into a position wherein the foot 72 engages the projection 45 and rotation of the cam 47 is ceased after a single revolution. Rotation of the cam acts firstly to pivot a lever 52 through engagement of the pin 66 therewith, the lever acting through a link 64 to pivot a latching lever 32 counterclockwise so that a cocking lever 29 is free to move with the hammer under the influence of a driving spring 22, a pin 57 on the lever 29 thereby being moved into engagement with the end of a loop 56 on a link 55. The pawl 70 is then returned to its operative position, and finally the link 55 is pulled rightwardly by pivotal movement of a lever 51 through the cam 47 to cock the hammer 18 and re-engage the cocking lever 29 with the latching lever 32 which will have returned to its operative position under a spring 37. The link 78 returns to its operative position in the slot 82 under a spring 80 when the key 19 is released.

Abstract: 1,250,226. Television. INTERNATIONAL STANDARD ELECTRIC CORP. 26 Feb., 1969 [28 Feb., 1968], No. 10264/69. Heading H4F. In a rastor type television system using dot interlace of ratio n to reduce the video signal bandwidth, each line sync. signal causes generation of a discrete train of sampling signals of frequency f e =f v .(LE/n) where f v  is field frequency, L is the number of lines in one field, E is the number of picture elements in one line, and LE/n is not integral, so that at each sampling signal the video input is coupled to an output circuit, and the system is characterized in that means responsive to the field sync. signals set up, for any one line, n different phase relationships between the respective line sync. signal and the ensuing sampling train, the sequence of phases repeating in successive sets of n frames so that the illusion of dot crawl is eliminated. Each frame may be formed of x fields if a vertical interlace ratio x, preferably where x = 2, is used. The dots of each field may lie on 45 degree diagonals to remove any directional diagonal emphasis. In a preferred embodiment, Fig. 1, at a transmitting station line sync. pulses delayed by a monostable 22 set a bi-stable 24 to actuate a clock 26 generating pulses of frequency f v .LE. After E pulse a counter 28 resets bi-stable 24 to stop the clock, and is itself reset by underlayed line sync. pulses. The clock pulses are divided by a bi-stable chain 33 e.g. 34, 35 for n = 4 and after sloping at 36 the resulting sampling train is fed, with the line and sync. pulses to an " OR " gate 44, which controls a gate 46 for passing line field and sampled video signals from a camera 12 to an output 48. Field sync. pulses (divided at 63 by x if line interlace is used) are fed to a further bi-stable chain 65, 67, with an equal number of bi-stables to those in chain 33, and the state of each circuit 65, 67, together with field sync. pulses or the frame frequency signal from 63 establishes the state of the corresponding circuit 35, 34 at the commencement of each field or frame, using " AND " circuits 68, 70, 73, 75. The chain 33 therefore assumes a different one of n initial counts at the beginning of each field or frame. In a modification, Fig. 6 (not shown), frame frequency pulses operate the chain 65, 67, but line sync. pulses are fed to the "AND " gates together with the outputs of elements 65, 67, so that the chain 33 is preset to the same initial count at the beginning of each line in any one field. A further " AND " circuit between elements 65 and 67 alters the relative phases of the elements to give a different sequence of phase relationships of the sampling trains. A similar circuit 11 may be employed at the receiver to resample and reshape the incoming video signal 48.

A transistor oscillator Q1, Q2, Q3, Q4 and TTF, for a telephone key sender, stabilized against variations in temperature and supply voltage, includes a phase-shifting network TTF containing only R and C components and preferably being a Twin Tee filter, and also a negative feedback circuit Q1A, R2, R1, Q2A, which for example limits the peaks of half cycles of one polarity (Fig. 2B, not shown) by providing a negative feedback path during those half cycles. In operation, one of an array of push buttons PB is pressed, inserting corresponding components into Twin Tee filter to produce a burst of oscillation from a high frequency oscillator and a low frequency oscillator, each oscillation having one of four values of frequency determined by the components inserted into the corresponding Twin Tee. On positive half cycles at the base of Q5, Q1A and Q2A are turned on, thus providing a negative feedback path, to limit the peaks of the half cycles by lowering the voltage at the base of Q3. The circuit is integrated and temperature effects in the limiting circuit are eliminated by forming R2 of silicon, having a positive temperature coefficient, and R1 of tantalum having a negative temperature coefficient. The effect of loop length is minimized by making the collector currents of Q1 and Q1A equal.

Abstract: 1,264,375. Vacuum switches; arc extinguishing in switches. GENERAL ELECTRIC CO. 24 June, 1969 [5 July, 1968], No. 31768/69. Heading H1N. An arrangement for interrupting a D.C., similar to that described in Specification 1,133,037, in which a capacitor 55, charged from the circuit to be interrupted, is discharged through the interrupting arc to cause an artificial current zero, is operated so that the charge on the capacitor 55 is reversed before the main contacts 27, 28 are separated so as to avoid the initial rise in arc current. An overload in the line 16 is detected by a relay 96 which applies a short pulse to a trigger electrode 86 to render a spark gap 58 conducting; the capacitor thus discharges through the spark-gap 58 and the main contacts 27, 28 (still closed). The discharge is oscillatory due to the inductance 60 of the circuit and therefore when the current through the spark-gap reaches zero the voltage across the capacitor has reached a maximum in the reverse direction. The large current pulse through the main contacts 27, 28 caused by the discharge of the capacitor causes a coil 51 to repel a disc 52 operating a valve 44 to open the main vacuum switch contacts 27, 28. A cam closes auxiliary contacts 97 causing a second pulse to render the spark-gap 58 conducting again causing the capacitor to discharge, in the correct direction, through the arc. To operate effectively the contacts 27, 28 must be opened very quickly after the current pulse in coil 50 (within 4 m.sec.); therefore the coil 50, valve 44 and pneumatic actuator 30 are mounted together at high voltage between the two series-connected vacuum switches 25. For use at low voltage only, where a short insulating coupling between valve 44 and disc 52 is acceptable, the coil 50 may be located in the capacitor circuit (Fig. 4, not shown). Series connected pairs of vacuum switches may be used for high voltage, each pair being operated by its own individual actuator 30 and coil 50. Several series-connected spark-gaps will also be used.
