Abstract: 958,313. Interrogating systems; semi-coriductor pulse circuits. GENERAL ELECTRIC CO. Feb. 26, 1962 [March 24, 1961], No. 7328/62. Headings H3T, H4L and H4U. [Also in Division B7] Apparatus for obtaining coded data from a number of coded stations, e.g. for obtaining assigned data from each of a number of railway vehicles when passing a location on a track, comprises a transmitter which provides a pulsed R.F. signal for interrogating the coded station, passive means at the station for transforming each received pulse into a time sequence of pulses coded in accordance with the assigned data and for transmitting the coded pulse sequence in the form of pulses of R.F. energy to the interrogating station and means at the interrogating station for producing an output signal corresponding to the data assigned to the coded station. An interrogator transmitter 7 transmits a B.F. pulse, when triggered by an interrogating pulse generator 6, which is received by a coded station receiver 3 and applied, after demodulation, to a pulse train generating means 1. This comprises an artificial delay line formed of a number of sections each comprising an inductance 30, a saturating core 31, a capacitor 32, an output winding on each core and switch means 34 for selecting particular output windings. As the interrogating pulse is propagated along the line, time spaced pulses are generated in turn in each output winding. The switch means determine which pulses are applied to the series circuit connecting the output windings, hence assuming each pulse represents binary 1 and the absence of a pulse binary 0, the sequence of pulses applied to transmitter 5 represents the coded information. predetermined by the setting of switches 34. Each pulse has sufficient amplitude to bias a tunnel diode 37 to the negative resistance part of its characteristic so that the coded information is transmitted in a series of R.F. pulses to the interrogated station. At the interrogator station the pulses are demodulated in receiver 8 and applied to a common input terminal of a series of tunnel diode coincidence circuits 9. The other input terminal of each coincidence circuit is connected to an output winding of one of the sections of a delay line 2 identical to that at the coded station. A pulse is applied to delay line 2 when the interrogator transmitter is triggered and this produces a series of time spaced pulses simultaneously with those generated at the coded station. Those coincidence circuits which receive an input signal from an output winding of delay line 2 when a pulse is applied to its other input circuit from receiver 8 switch to their second stable state and supply an output (binary 1) and those which receive an input from delay line 2 during the absence of a pulse from receiver 8 remain in their first stable state and supply no output (binary 0).

Abstract: 397,399. Darning. JAMIESON, T. W., Charity Farm, Shotley, near Ipswich. March 13, 1933, No. 7539. [Class 112.] A machine for darning comprises two alternately reciprocating needles cooperating with a single looper which places the loop of one needle on the other needle. The thread loops are thus interconnected and fill up the hole. The thread is passed round tension discs, through the eyes of springs and through the eyes of the needles 9, 9a. The material to be darned is placed on the holder 35 which is fullv drawn out to the left of the channelled arm 26. The arm 26 is in its extreme right hand position so that the stud 41 is at the end of the inclined slot 25a. In this position, the needles enter the sound portion of the material at the edge of the hole to give the " darn " an anchorage. The handle 32a is then turned. One complete turn effects stitch 1, Fig. 7, and the rack 30 and hence the material on the holder, is moved one tooth to the left. The next turn of the handle forms stitch 2, Fig. 7, the holder and material being again moved through one tooth. Successive turns of the handle form the stitches 1 .. 17, Fig. 7, so filling the hole. The stitches 8 .. 14 are made by a reverse rotation of the handle, causing a reversal of the feed by the aid of a crescent-shaped pawl. The stitches referred to are interconnected loops, each row being connected to adjacent rows. When the needle 9 has descended, the looper 19 moves from the left and the hook 39a, Fig. 3, catches the thread and draws the loop under the needle 9a. The needle 9a descends into the loop as the needle 9 rises and draws the loop round the needle 9a up to the material. The looper then moves to the right and the hook 39 catches the thread from the needle 9a and draws it under the needle 9 which descends through the loop as the needle 9a rises.
