Title: Improvements in or relating to receiving arrangements for teleprinter signals
Inventor: CLARK RAYMOND LAURENCE
IPC: H04L27/14
Filed: 1948-09-24
Abstract: 666,231. Code telegraphy. STANDARD TELEPHONES & CABLES, Ltd. Sept. 24, 1948, No. 25007/48. Class 40 (iii). A telegraph receiver for marking and spacing teleprinter signals comprises a two-condition electronic trigger device employing first and second thermionic valves each including a screen grid and a suppressor grid and each having its anode cross-connected to the screen grid of the other valve so that conduction of either valve cuts off the other, means for applying input marking and spacing signals to said device to cause the conduction respectively of said first and second valves and means for applying a negative impulse to the suppressor grid of said second valve shortly after the cessation of input signals to trigger said device into the marking condition, if not already in that condition. In the circuit arrangement shown, a negative spacing impulse applied to the grid of the pentode 3 renders the valve non-conducting and makes valve 4 conducting and a subsequent marking impulse applied to the valve 3 reverses the condition of the valves. The impulses derived from the anode circuit of the valve 3 are fed via a D.C. amplifier 12 to an output terminal 13. The output from the amplifier 12 is also fed through a blocking condenser 18 and a rectifier 19 poled so that a condenser 21 is charged negatively and cuts off a triode valve 14. When signals have ceased the condenser 21 discharges through a resistance 20 which is short circuited by a rectifier 23 during the charging operation. The discharge of condenser 21 allows the valve 14 to conduct and apply a negative pulse to the suppressor grid of the valve 4 which is made non-conducting if it had not been left in that condition. The cutting-off action of the valve 4 also applies a positive pulse to the grid of the valve 14 which accelerates the pro- - cess of the cut off of the valve 4. The resistance 20 is such that the condenser 21 discharges more slowly than it was charged. A rectifier 25 prevents the suppressor grid of the valve 4 from acquiring a positive charge. The mark-to-space rates of the output signals can be varied by an adjustable tapping point on a potentiometer resistance 5 connected across the equal anode load resistances 6, 7 of the valves 3, 4. The input signals at the terminals 1, 2 may be derived from a frequency-modulated transmission system. Specification 652,154 is referred to.

[Class 106 (iv).] A recording-mechanism for measuring instruments and apparatus comprises an attachment with an auxiliary index connected to a recording element the index being controlled manually or automatically by coupling it directly to the moving member so as to follow or copy its movement. As shown in Figs. 1 and 2, the attachment comprises a casing with drums 4 carrying a record-strip and one or more displaceable slides 6 carrying marking elements 1 and a stylus 2 for marking time graduations.. Each slide is connected to an auxiliary index 8 co-operating with a scale plate 9 and adapted to be moved by hand in coincidence with the rectilinear movement of the moving element of the measuring instrument. If the attachment is separated from the instrument the auxiliary index may be connected to the slide by threads 17 in sheaths 21. To copy the angular movement of a pointer the auxiliary index is arranged as shown in Fig. 3. A frame 10 mounted on the face of the dial has a slot 29 in which is mounted a sliding piece 11 on which is pivoted the auxiliary device 12 that is movable by hand over the scale 15. In one mode of operation the slide 11 is clamped in the central position and the pivot 13 of the arm 12 is arranged coincident with the instrument pointer. To the arm 12 is clamped the ends of a thread 17 guided around pulleys 19 and on the arcuate surface of a member 18 forming part of the slide. Movements of the arm are transmitted by the thread to the slide 6 and marker 1. The device of Fig. 3 may be used also with rectilinearly moving pointers by clamping the arm 12 in its central position and moving the slide 11 along the slot in coincidence with the pointer movement. An example of the use of the device is shown in Fig. 5, wherein the speed and power of a generator are recorded by the markers 1, 1<1> of an attachment the threads 17, 17<1> of which are operated by the coupling sleeve 23, 24 of a speed governor and by following the pointer of the power meter 25<1>.
