Abstract: 1335583 Variable speed rollerway conveyer GOODYEAR TIRE & RUBBER CO 3 Dec 1971 [4 Jan 1971] 56250/71 Heading B8A In a passenger or load-carrying conveyor, the acceleration and deceleration sections comprise a plurality of driving rollers having axially varying diameters, which rollers engage rails mounted on driven passenger- or loadsupporting means, the driven speed of the supporting means being changed by engagement of the rails with the rollers at different axial positions along the rollers. In the Figure, rails 17 and 18 are canted such that the forward end F contacts the rollers 23 at a slowermoving smaller diameter section 39 while the rearward end R contacts a faster-moving larger diameter section 38. Since the rollers are driven at progressively higher speeds in the direction of the arrow, the rails contact portions of the rollers moving at the same speed, thus preventing slippage while the passenger cab on which the rails are mounted accelerates. Deceleration occurs in a similar fashion. Transverse movement of the passenger- or loadcarrying cabs is constrained via engagement of angles 34 with cam rollers 35 which rotate about a vertical axis 36. In an alternative embodiment (Figs. 5-7, not shown) the rollers are driven at a constant speed and acceleration or deceleration occurs by varying the spread of pivoted rails attached to the cab, which rails then contact the rollers at different axial positions depending on the transverse distance between the longitudinal parallel rails.

Patent GB-566106-A (GB)
Abstract: 566,106. Electromagnetic ammeters and voltmeters. GALL, D. C. Sept. 7, 1943, No. 14668. [Class 37] A moving coil instrument is so constructed that it is sufficiently sensitive to indicate small currents while being substantially unaffected by accelerations or decelerations imparted to the instrument as a whole. The moving coil 1, Fig. 4, is very light and is wound to a small rectangular shape, for example, with long sides 1.5 cm. and short sides 1 cm. in length. Centrally of each short side is attached a short length 2 of fine copper wire with its axis in the central plane of the coil 1. Each of these wires extends within the coil and fits closely within the bore of a fine glass capillary tube 3, the opposed ends of the wires 2 being spaced apart and cemented in the tube. The outer ends of the wires are cut away for half their thickness to produce a diametral flat face to each of which is attached one end of a fine phosphor bronze strip 4, to which the ends of the coil are connected. The other ends of the suspension strips 4 are each attached to a tension spring 5; the springs being adjusted to produce a considerable tension in the strips 4 and preferably being of flat spiral form. A small mirror 6 is attached to the glass tube 3, as by being clipped in a light metal frame 7 which is soldered to a few turns 8 of wire wound on and cemented to the glass tube 3. Fine wires 9 are attached to the coil or, as shown, to one of the supporting wires 2 for balancing the coil, which may be effected by clipping off or bending the wires or by loading with a few turns of extremely, fine wire 10. The central soft iron core piece 14, Fig. 2, has a slot 16 to accommodate the glass tube 3 and mirror 6, the slot being widened at 16a to permit movement of the mirror and allow the beam of light to be reflected without obstruction. The coil is rendered dead-beat by electromagnetic damping, as by employing a low resistance external circuit, or by shunting a low resistance across the coil, or by providing a .short-circuit turn on the moving coil. The mirror 6 may be formed integrally with the glass tube 3 by flattening this at its centre to disc shape and silvering one of the flat surfaces.

Abstract: 1410807 Controlling power in A.C. loads WESTINGHOUSE ELECTRIC CORP 8 Dec 1972 [27 Jan 1972] 56854/72 Heading H2H [Also in Division H3] A switching circuit comprising a three electrode semi-conductor switch SCR1 includes means for sensing the voltage across the main electrodes 7, 8 and forming a conductive path from a voltage source 11 to the control electrode 9 when the main electrode voltage reaches a predetermined value. As described, a circuit for controlling the supply of A.C. to a load comprises a pair of back-to-back thyristors, SCR1, SCR2, each having a respective control circuit 10 operated by a common control signal V 2 , the arrangement ensuring that the thyristors remain conductive under light load conditions. Application of a control signal V 2  to light emitting diode 29 turns on photo-transistor 30 to apply base drive to transistor Q3. Q2 can therefore become saturated, but only if the voltage across SCR1 exceeds the sum of the junction voltage drops of diode 24, the baseemitter voltage drop of transistor Q2, and the collector-emitter voltage drop of transistor Q3. When this occurs, Q2 saturates turning on Q1 to provide gate drive from source 11 to turn on SCR1. If the load current is sufficient to maintain SCR1 conducting the gate drive is then removed since the voltage between its main electrodes falls below the threshold. If however the load current is too low to sustain conduction gate drive will be maintained, and will vary inversely with load current. SCR2 is controlled in a similar manner.
