Title: Improvements in or relating to inductive train influencing arrangements
IPC: B61L3/12
Filed: 1931-02-10
Abstract: 383,606. Inductive control of trains from track. VEREINIGTE EISENBAHNSIGNALWERKE GES., Siemensstadt, Berlin. Feb. 10, 1931, No. 4148. Convention date, March 18, 1930. Void [Published under Sect. 91 of the Acts]. [Class 105.] Relates to train control apparatus inductively actuated from the track when a train control is to be effected. The arrangement comprises a brake valve magnet V which is energized over a contact i<1> of the impulse relay Ji, a front contact c2 of a control relay C, and a contact l, whichisclosed when a manual brake-release key L is in its unactuated position. A magnet Ja to pull over the armature J when the track impulse is received in the relay Ji is also energized over a front contact c1 of the relay C and contacts b2 of an " instruction key" B and g of a speed controlled device. The brake application, which is initiated when the armature J opens contact il, is cancelled by depressing the brake release key L to close contact l2, thereby short-circuiting the pullover magnet Ja so that the armature J is able to move over to the normal position shown, the impulse circuit now having travelled beyond the sphere of action of the track circuit and being in normal condition. The brake release key L must not be maintained depressed as only when the key is unactuated and the contact h1 closed can the brake magnet V be energized to cancel the braking. An impulse may be rendered ineffective by placing the " instruction key " B on contact b<1> so that the pull-over magnet Ja is short-circuited over the armature contact i2 and does not therefore pull off the armature J ; the train speed must be low enough to close the contact g over which the control relay C is energized otherwise the brake magnet circuit is open at contact c2.

Title: Method and apparatus for the synchronous frequency modulation of binary data
IPC: H04L27/20
Filed: 1965-02-01
Abstract: 1,039,148. Data transmission. LENKURT ELECTRIC CO. Inc. Feb. 1, 1965 [Feb. 6, 1964], No. 4328/65. Heading H4P. To transmit binary data by frequency shift, the data is combined with clock pulses to provide pulses of discretely varying repetition frequency. In a first embodiment the data is gated with clock pulses at a multiple of the bit rate, so that the gate gives pulses only during the zero bits. These pulses are combined with clock pulses of the same P.R.F. but 180 degrees out of the phase with the first clock pulses. The resultant signal feeds a toggle, resulting in square waves changing between one frequency and another half its value to represent zero and one bits. The square wave is passed to a band-pass filter to give a sinusoidal output, the pass-band being defined by the two frequencies of the square wave. Transition from one frequency to the other takes place at zero amplitude. In a second embodiment, the input data is first converted to differential code by gating it with the second clock pulses, and converting the resultant pulse train to square waves by a toggle. The output of this toggle feeds the system described above, but in this case the output of the filter will be of three frequencies, a centre frequency indicating one bits and either of the upper and lower frequencies indicating zero bits.

Abstract: 1380167 Digital data transmission systems WESTERN ELECTRIC CO Inc 1 Feb 1972 [9 Feb 1971] 4545/72 Heading H4P To improve the self-synchronization properties of the variable length coded signals from a sequential prefix encoder fed with fixed length coded signals, logic circuitry selectively forms sequential rearrangement of signals input to the encoder and selectively complements signals output from the encoder. Likewise at a receiving decoder corresponding logic circuitry selectively complements signals input to the decoder and selectively forms sequential rearrangements of signals from the decoder. In the sequential prefix encoder shown in Fig. 7, a difference circuit 11 forms the difference between a di-bit input signal i and the preceding di-bit input signal 1 delayed by circuit 10<SP>1</SP>, for presentation to sequential prefix encoder 12<SP>1</SP> via an interposing logic circuit which forms the reflections of the difference if the most significant bit of the delayed di-bit is a one bit. The output of the encoder passes through a circuit 22 which complements the coded signal if the least significant bit of the delayed di-bit is a one bit. In the decoder of Fig. 8, circuit 17<SP>1</SP> adds a delayed output signal to the output from reflecting logic circuitry 24 to form the original input signal, and the delayed signal is also applied to logic circuitry 23 which complements the input signals if the least significant bit of the delayed di-bit is a one bit. Reflecting logic circuitry 24 forms the reflection of the decoded signal if the most significant bit of the delayed di-bit is a one bit. In another arrangement (Fig. 13, not shown), the modification logic circuitry is combined with the subtraction logic circuitry.
