Filed: 1974-12-13
Abstract: 1495288 Control of D.C. motors COPAL CO Ltd 13 Dec 1974 [14 Dec 1973] 54041/74 Heading H2J [Also in Division G3] A rotary indicator which is advanced at regular intervals when a motor 8 is energized has a series of indicator flaps 1 to show, for example, the days of the week, and at least one further flap 1-1, 1-8 which is displayed to indicate an abnormal condition such as low battery voltage. At a point of rotation of flap drum 2 corresponding to the abnormal condition indication a cam recess 16 causes blade 22 of switch SWa to move from contact 23 to contact 24. The motor drives the drum via a worm 7 and gears 4-6, gear 5 and a cam 9 making one rotation for each step of the drum. The cam 9 controls a further switch SWb which, once the motor has been started by a control pulse applied to an SCR, is closed to keep the motor running for a complete revolution of the cam. The motor circuit, Fig. 2, includes a transistor 25 which is turned ON by the SCR and held ON by the switch SWb. Signals from a battery check circuit are applied at terminals 28, 29 to keep transistors 26, 27 respectively OFF and ON while the battery is healthy. When the drum 2 reaches its fault indication position and blade 22 moves to contact 24 as described above, the motor remains energized since transistor 27 is ON, so that the fault indication flaps are passed over and the next day indication is given. If the battery voltage drops, the check circuit turns the transistors 26, 27 respectively ON and OFF so that the motor becomes energized and runs until lever 19 drops into cam recess 16 to change over the switch SWa; the drum 2 then stops with flaps 1-1, 1-8 displayed. In a modified control circuit, the battery check circuit controls a relay (31, Fig. 3, not shown) and the transistors 26, 27 are omitted.

Abstract: 1322457 Extracting castings from sand moulds PONT-A-MOUSSON SA 23 Nov 1971 [3 Dec 1970] 54309/71 Heading B3F Apparatus for removing castings from a line of sand moulds 3 comprises an overhead conveyer having suspended hooks 12 which can be raised and lowered, means 25 for guiding a downwardly moving hook to a position adjacent a mould, and means 29 for displacing the guide means 25 so as to cause the hook to penetrate the mould and engage the casting 2. In the embodiment shown in Fig. 2, the guide 25 is pivoted at 28 to a fixed support 27 and may be moved by a jack 29. In operation, a rail segment 15 is lowered so that a pin 24 on the hook 12 engages in grooves 26 on the guide 25. After the hook has reached the position shown in Fig. 2, the jack 29 is activated to bring the guide 25 to a vertical position, thus causing the hook to penetrate the mould and engage the sprue and runner of the casting. The rail segment 15 and the hook 12 are now raised, this withdrawing the casting from the mould. After the pin 24 has emerged from the top of the guide 25, the latter is moved back to its original position ready for the reset cycle. The embodiment shown in Fig. 9 is used when two lines of moulds are located adjacent one another. After the casting has been removed from a mould in line 1 by the apparatus shown in Fig. 2, a spade 32 is inserted between the two lines and then moved to the left by a jack 34 so as to provide a space 38 into which the hook 12 may be lowered. After the pin 24 has emerged from the lower end of the guide 25, the hook is guided by contact with the spade 32 and mould 3a and is caused to penetrate the mould by moving the spade 32 to the right from the position shown in Fig. 9. During the upward movement of the hook the pin 24 bears against a track on the outside of the guide 25, the guide being freely pivotable about a fixed support and having its pivotable movement limited by abutments (36) and (37).

Title: Improvements in or relating to Devices having Stabilised D.C. Motors.
IPC: H02P7/292
Filed: 1967-11-29
Abstract: 1,154,076. Control of D.C. motors. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 29 Nov., 1967 [2 Dec., 1966], No. 54356/67. Heading H2J. [Also in Division G3] A D.C. Motor 3 is supplied from A.C. source 4 through a controlled rectifier 1, the speed being stabilized by feeding back a signal representing the armature voltage to the gate circuit of the rectifier, the cathode of the rectifier 1 being connected to the cathode of a diode 2 through which the motor is supplied during alternate half-cycles of the supply, the gate of the rectifier 1 being connectible through diode 14 to the upper armature terminal. The anodes of the rectifiers 1, 2 are connectible to respective tappings in a supply transformer the upper armature terminal being connectible to an intermediate tapping 7. High-speed operation of the motor is provided when switches 12, 15 are in their upper positions, the motor being supplied through tappings 10 or 11 and current-limiting resistors 17 or 18 in accordance with the position of a change-over switch 16. The gate of the rectifier 1 is then connected to its anode for operation as an uncontrolled diode. In the lower positions of the switches 12, 15, the voltage across the motor is fed back through diode 14, between the gate and cathode of the rectifier 1. If the speed is excessive, rectifier 1 becomes blocked and the motor is fed only through the diode 2. A temporary reduction of armature current causes the rectifier 1 to become non- conductive for a number of periods until the armature current is restored to its former value whereupon the controlled rectifier conducts for a number of half-periods, as required for maintaining the speedat a substantially constant value. In a modification the rectifier 1 remains out of operation when the switches 12, 15 are in their upper positions, the motor being fed through resistor 17 or 18 and diode 2. In a further embodiment, the rectifiers 1, 2 are included in a bridge circuit comprising third and fourth diodes. An inductor provided with tappings is connected in the bridge circuit to adjust the no-load current of the motor. The motor may be of the shunt type, or may have a series field winding which is not, however, included in the control circuit of the rectifier 1. A variable resistor may be connected in series with the diode 14.

Title: V. F. Receiver
IPC: H04Q1/46
Filed: 1967-11-30
Abstract: 1,179,614. Voice-frequency receivers. INTERNATIONAL STANDARD ELECTRIC CORP. 30 Nov., 1967 [3 Dec., 1966], No. 54595/67. Heading H4R.  A voice-frequency receiver distinguishes single frequency signals by the fact that they exceed lower and upper thresholds during each positive excursion whereas more complex signals may have positive excursions that exceed only one of the thresholds. As illustrated the invention is applied to a receiver for two 1-out-of-n V.F. codes, one signal being in an upper band passed by Vra while the other signal is in a lower band passed by Vrb. Considering the upper band alone: a received signal is applied to a threshold device V11 tied to a low threshold potential Uv1 (possibly zero), and a threshold device V21 tied to a high threshold potential Uv2. The potential Uv1 is taken from a potential divider and is fixed while the potential Vv2 is varied by a transistor PS in accordance with the average value of the received signal. Both thresholds may be fixed or both may be dependent on average signal value. When the lower threshold is exceeded a differentiator DG11 pulses a delay circuit T11 and an AND gate U11. When the upper threshold is exceeded a differentiator DG21 pulses a delay circuit T21 and an AND gate U21. After the differentiator outputs have subsided the delay circuit outputs set or reset a bi-stable FF1. So long, therefore, as FF1 is not already in the state to which a delay circuit output directs it the gates U11, U21 will remain closed. If, as will happen with a signal waveform of single frequency, a positive-going excursion crosses both thresholds in turn, bistable FF1 is switched back and forth the gates U11, U21, remaining closed. If the waveform is such, however, that it only exceeds one of the thresholds during a positive-going excursion (either because the excursion is not great enough to reach the high threshold or starts from above the low threshold) one of the thresholds is exceeded twice without the other being exceeded in between. In such a case FF1 is already in the state to which a differentiator delayed output drives it so that AND gate U11 or U21 opens to set a bi-stable FF3 to record that a valid signal is not present. Bi-stable FF3 is scanned periodically by a resetting input Ab to determine if a valid signal is present (FF3 found reset) in order to summon up a common receiver to determine which of the n frequencies is present, such determination being made with the use of tuned circuits or, as from terminal Z1, by counting the number of times the upper threshold is exceeded in a given time. Considering both signal bands, the lower band delivered over Vrb is treated in exactly similar fashion. Since, however, a signal in only one band would be invalid in a 2,1-out-of-n, code a detector PK requires that the average signal strength in both bands exceeds the minimum threshold UV1 and, if this is not so, it sets bistable FF3 to indicate that no valid signal is present.
