Title: Improvements in and relating to the control of electric motors driving sections of aplant for carrying out a continuous process
IPC: H02P5/50
Filed: 1957-06-24
Abstract: 859,669. Control of several D.C. motors. SOC. GENERALE DE CONSTRUCTIONS ELECTRIQUES ET MECANIQUES ALSTHOM. June 24, 1957 [June 26, 1956], No. 19813/57. Class 38 (3). [Also in Group XXXV] In a system for electric motors driving individually a master section and ordinary sections of a plant and including a circuit whereby the speeds of all the motors may be varied simultaneously, an amplifier having output connections to the speedcontrol circuits of two motors driving two adjacent ordinary sections is provided so that control of the amplifier for changing the speed of one motor causes a change of speed of the other. The speeds of motors A1-A3 of Ward Leonard sets A1-A3, B1-B3, are maintained constant at speeds predetermined by potentiometer H by the action of the difference between the output voltage of the tachometer generators I1-I3 and the voltage G from the master section on the fields D1-D3 of the generators. The difference is applied to coil K1 of a preamplifier W1, which may be a push-pull magnetic amplifier, supplied at Q from a 1000 C.P.S. source to control field windings L1, L<SP>1</SP>1, controlling an amplidyne C1 feeding the generator fields. The tachometer voltages may be adjusted by potentiometers J1-J3. Potentiometers M2, M3, and magnetic amplifiers P2, P3, are provided for effecting a change of speed of motors A2 and A3, the output from the magnetic amplifier A2 energizing a coil R2 to oppose the effect of coil K2 in its own section, and through a potentiometer U3 a coil T3 in amplifier P3 to correspondingly modify the speed of the succeeding section. Negative feed-back is provided by coils S2, S3. The wipers of potentiometers U3 and M3 are ganged to maintain the ampere turns of T3+N3=N2. In a modification described with reference to Fig. 2 (not shown), the output from the speed-changing magnetic amplifier is connected in series with the reference voltage and the opposing coils R2 in the pre-amplifiers are dispensed with.

Title: Improvements in and relating to load lowering and lifting
Inventor: HUMPHRYES JAMES ANTHONY
IPC: B66C3/06
Filed: 1955-07-09
Abstract: 797,839. Load-lifting devices with automatic control; grabs. BRAITHWAITE & CO. ENGINEERS, Ltd. June 26, 1956 [July 9, 1955], No. 19912/55. Class 78 (4). Equipment for load-lowering and lifting, comprising means for suspending the load, as for example a winch and cable, and wherein, on conclusion of lowering, a supplementary operation on the load is effected automatically under the influence of a controlling condition which thereupon arises, namely slackening of the means of suspension on being relieved of the load, is characterized by means for automatically requiring repetition at least once of the controlling condition before the supplementary operation actually takes place. As shown, the equipment is suspended from a cable attached to a slide 1, Fig. 1, having limited movement between stops 9, 10 relatively to a cage 4 carrying pivoted members 3 gravity-biased by lugs 6 which support the load 2 when teeth 12 are engaged by a crossbar 11 on the slide 1, as shown in the left-hand side of Fig. 1. When the cable slackens the cage is supported on the load by a flange 7 and the stop 9 engages the teeth 12, as shown in the right-hand side of Fig. 1. Each time the cable becomes taut after slackening, the members 3 take up the successive positions b, c, d, Fig. 1, the load being released only when position d is reached. In an embodiment for closing the jaws of a grab, the ends 28, Figs. 4a, 4b, of catches 29 act as bearing blocks between a tubular fair lead 21 fixed between side plates 20 on the grab body, and a button 27 on the end of a rod 25 carried by the supporting cable, the blocks being gradually withdrawn under the control of an escapement device, finally allowing the button 27 to pass through the fair lead, taking with it the cable extension 26 for closing the grab jaws. The catches 29 are pivoted on shafts 30 engaging slots 31 in the plates 20 and slots 38 in T-shaped plates 35 guided for vertical movement and carrying racks engaging pinions 39, Fig. 4b, mounted on brackets fixed to the plates 20. As the plates 35 descend, the ends 28 of the catches move outwards and downwards after the heavier ends 32 meet stops 24. The pinions 39 are rotated one tooth at a time, on each slackening and re-tightening of the cable, by a bobbin 41 slidable between a shoulder 42 and a top flange 43 on the rod 25, and urged upwards if necessary by a'spring (not shown). The pinions have cylindrical recesses 46, 47 to allow the passage of the flange 45 and button 27. In a modification, Fig. 7, the fair lead 21b is movable vertically and carries the racks on its inner surface, the catches 29 being in the form of bell-cranks having fixed pivots, their horizontal arms being engaged by the fair lead at the lower end of its travel, and extensions on their vertical arms releasing the button 27. In this embodiment the bobbin 41 is fixed to the shaft 25.

Title: Overrun brake control
Inventor: HAHN PIERRE
IPC: H03K3/037
Filed: 1966-05-05
Abstract: 1,150,076. Overrun brakes for trailer vehicles. P. HAHN. May 5, 1966 [ May 5, 1965], No. 19933/66. Heading F2E. An overrun brake control for trailer vehicles comprises a coupling rod connected between a tractor vehicle and an hydraulic damper on the trailer, the damper being of the oleopneumatic type which is provided with a compressed air chamber 9, separated from the hydraulic fluid by a free piston 10, to provide initial resistance to collapse of the towbar assembly, a trailer brake lever or levers being acted on by a force derived from that acting on the coupling-rod through a parallel connection, e.g. a spring, so arranged that the derived force is different. As shown, a spring 16 is arranged in parallel with the damper and acts on lever 11 of the trailer brake linkage whenever movement of the coupling-rod 2 occurs, whilst the damper 7 acts directly between the tractor and trailer. For this purpose, the coupling rod 2 supports a tube 3, which slides within a tube 6 secured to the trailer, and has an extension-rod 15 extending rearwardly from it to connect with the piston rod 21 of the damper 7, the latter being secured at 8 within the tube 6. Spring 16, which surrounds the rod 15 and is enclosed within a tube 12, acts on the lever 11 via a collar 13 which includes pins 14 engaging slots in bifurcations of the lever 11. Extension of the coupling is limited by a stop-ring 18 and interposed resilient ring 19. The relay lever 11 is pivoted at 26 on a clamp 28 secured to the tube 6, and acts on a rod 17 coupled to the trailer brakes, the lever giving a mechanical advantage of more than 2:1. A pneumatic or hydraulic slave cylinder may also act directly on the trailer brakes under control of the tractor brake system. A hand-brake lever formed by a pair of lever arms 23 is also pivoted at 26 and engages with play in extensions of the coupling pin which connects the linkage 17 to the lever 11. A pawl 26 on the hand-brake lever engages a ratchet 27 formed on the clamp 28. A chain 25 is connected between the lower end of the handbrake lever and the tractor to apply the brakes automatically if the coupling should become disconnected.
