A sag carrier for an aerial cableway is driven along the main cable 25 by a driving rope 7a which is reeved to drive pulleys 1, 2 which in turn drive pulleys 3, 4, Fig. 2, around which is reeved a rope 7b, Fig. 1, which is held stationary or moved in the opposite direction from the rope 7a. The sag carrier is employed in a system in which a number of carriers are moved by the same ropes 7a, 7b at speeds such that they always divide the distance between the load carriage and the adjacent terminal in the same proportions. The proper speeds may be provided by varying the diameters of the sheaves 1, 2, 3, 4 or by varying the ratio of gearing between the sheaves on one side of the carriage and those on the other. In the arrangement of Figs. 1 and 2 gears 31, 32, 33 and 34, 35, 36 join the sheaves on each side of the carriage and the drive from the sheaves on one side to those on the other is through a clutch 15 which may be declutched by cams 38, Fig. 1, operated by buffers 16 when the trolleys come into contact with one another. Each trolley is supported on the track 25 by rollers 30 and counter-rollers 24. The ropes 7a, 7b may comprise the two runs of an endless rope secured to move with the load carrier or separately driven, or the ropes 7a may be an independent endless rope while the rope 7b is a fixed rope or an endless rope driven in the opposite direction from the rope 7a. The pairs of sheaves 1, 2 and 3, 4 may be replaced by a single sheave on each side of the trolley and the ropes 7a, 7b may be reeved around these and around idler pulleys. The drive between the sheaves on opposite sides of the trolleys may include an epicyclic gear in which an annulus is carried by one sheave, a crown-wheel by the shaft of the sheave on the opposite side of the trolley, and the planet pinions by the frame of the trolley.

Abstract: 641,753. Pulse generating circuits. DEPARTMENT OF COMMERCE, DIRECTOR OF THE OFFICE OF TECHNICAL SERVICES OF. Feb. 27, 1948, No. 5968. Convention date, Oct. 19, 1945. [Class 40 (vi)] A pulse generator in which the pulse width and repetition frequency can be adjusted independently comprises a first capacitor which is charged at an adjustable rate and subsequently discharges through a main path comprising a first valve and a resistor in series and an auxiliary path comprising controllable means and a second resistor and' valve connected in series so that current flowing in the second resistor renders the controllable means non-conductive. A second capacitor has one terminal connected between the first valve and resistor and the other terminal connected between the controllable means and the second resistor the discharge rate of the second capacitor through the second resistor and valve determining the width of the output pulse. In the Figure capacitor C1 charges through resistors R1 and R3 from the D.C. supply at a rate adjustable by the setting of R1. At a predetermined voltage the gasfilled valve N1 fires and discharges capacitor C1, N1 then being extinguished. While capacitor C1 charges valve V1 conducts and capacitor C2 is charged to the voltage across the high value resistor R6 so that when N1 fires the increased voltage across resistor R4 causes tube N2 to fire the discharge capacitor C2 via resistors R4, R7 and N2, the current flow through resistor R7 causing valve V1 to cutoff. When N2 fires valve V2 conducts and capacitor C3 is charged from the D.C. supply via resistor R2 and tube N2 until its decreasing grid voltage causes valve V2 to cut-off when capacitor C3 discharges through resistor R10. When N2 is extinguished valve V1 again conducts and capacitor C2 commences to charge again. The width of the output pulse produced across capacitor C3 is determined by the period for which N2 fires which depends upon the charge acquired by capacitor C2 which can be adjusted by varying the valve of this capacitor.
