IPC: B61G1/28
Filed: 1921-05-06
Abstract: 180,193. Grahnstr÷m, F. May 6, 1921. Couplings, automatic.-In an automatic coupling in which a coupling-pin is held in the open position by a spring-controlled member which, on impact, is moved rearwardly by the coupling- link of another wagon to release the coupling- pin, the member that holds the coupling-pin in the open position is connected at its outer end with an impact plate carrying a supporting- bracket for the coupling-pin, which plate is held pressed against the pin by a spring. The coupling-pin 5 is of inverted U-shape, the front leg of which rests on a bracket 7 attached to a plate 8 supported by two spring-controlled horizontally spaced rods 9, 10 carried in guide-plates 11, 12. The rear leg of the coupling-pin is weighted and is guided in plates 3, 4. A lever 18 is pivoted at 17 to the rear leg and has a forked end between the jaws of which is an inclined face 28 working against a stop 22 on a spring-controlled catch 15. This catch is pivoted to the rear leg of the coupling-pin at 14 and angages the under-surface of the bar 4 when the coupling-pin is in the down position; a projection 23 at the upper end of the catch engages with an inclined surface 24 on the rod 10 when the pin is raised to the set to couple position. On the link of the opposing coupler striking the plate 8, the pin 5 is dislodged from the bracket 7 and engages the link. In uncoupling. the wire 20 is wound up on a winch situated on the vehicle, the lever 18 turns about its pivot 17 and the inclined surface 28 pushes the catch 15 out of engagement with the under surface of the bar 4. Further winding of the wire 20 raises the coupling-pin on to the projection 7, and the projection 23 engages the inclined surface 24 on the bar 10 and retains the catch 15 in the unlocked position. When the vehicles are to be shunted, the plate 8 is withdrawn rearwardlv bv the wire 25 until the inclined surface 24 clears the projection 23, the catch 15 is then drawn inwardly by the spring 16 until the under side of the catch rests on top of the bar 4 and retains the coupling-pin in the raised position.

Title: Motor control apparatus
IPC: H02P7/29
Filed: 1972-03-21
Abstract: 1445972 Automatic control systems PRINTED MOTORS Ltd 21 June 1973 [21 March 1972] 13243/72 Heading G3R [Also in Division H2]  A control system as shown in Fig. 1 and generally similar to that described in Fig. 4 as modified by Figs. 6 and 7 of Specification 1416681, is provided with a tachogenerator 31 coupled to or integral with the low inertia motor 30 and supplying a speed signal to the input of amplifier 20, whereby the droop of the speed-load characteristic is limited. The negative feedback effect of the speed signal on the error signal at input terminal 21 is explained for error signals just outside the dead band defined by stages 27, 28, Figs. 2 and 3 (not shown). These stages receive the output of a variable gain stage 24, 25 and produce pulses at a rate and of polarity respectively determined by the magnitude and polarity of the error signal. The pulses are provided by a reference oscillator 33 consisting of an amplifier (50) with feedback through a variable resistor (55) and a phase shifting network, the amplitude and frequency of the amplifier output being adjustable by a potentiometer (51) which varies the proportion of the non-linear effect of diodes (52, 53), Fig. 5 (not shown). The oscillator produces a square wave output of unity mark/space ratio. The control system of Fig. 1 is described in detail, Figs. 4, 7 and 8 (not shown). Regulation may be improved by passing the signal from tachogenerator 31 through a parallel R.C. circuit (71, 72) to the input of amplifier 20, which is shunted by a capacitor (73) in this case to compensate for the loss of gain in the amplifier, Fig. 10 (not shown). In another modification of amplifier 20 to protect against malfunction caused by transient inputs thereto, limiting diodes (85, 86) are reverseparallel-connected across its input and its feedback circuit consists of a resistor in parallel with the series combination of a capacitor (81) and reverseparallel-connected limiting diodes (82, 83), Fig. 11  (not shown). The output pulses from oscillator 33 may be modified to comprises two waveforms phase displaced by 180 degrees, to prevent maloperation of the motor power stage, Fig. 4 (not shown) when a sudden change in polarity of the error signal tries to produce a corresponding sudden reversal of the motor. The feedback circuit of amplifier 20 may comprise the series combination of a resistor and capacitor, Fig. 14 (not shown). Uni-directional drive of the motor may be provided by using only two thyristors with a modified firing circuit, Fig. 15 (not shown).
