Patent GB-2139831-A (GB)
Title: AC elevator system with battery charging control
Inventor: KAMAIKE HIROSHI
IPC: H02J7/00
Filed: 1984-05-04
Abstract: An induction motor 6 of an elevator is energised by a variable-voltage, variable-frequency inverter 5 supplied by a battery 4, and the charging rate of the battery 4 from source 1 is controlled in dependence on the rate of discharge of the battery to the inverter 5. A control circuit 14 includes relays for sensing balanced, heavy and light loading of the elevator cage 9, ascent, descent, acceleration, deceleration and constant speed operation. When the motor 6 is drawing heavy current during acceleration or constant speed operation, a command circuit 15 responsive to the relays causes the battery to be charged via a charging circuit 11 at a rate which is greater during such acceleration than during such constant speed operation. At other times, such as constant speed and deceleration stages of a heavy load descent, the battery is regeneratively charged via the inverter 5, the command circuit 15 then causing the battery to be discharged by a circuit 12 at a rate which is higher during the deceleration than during the constant speed operation. The system thus tends to maintain the battery at a constant charge state. Circuit 14 is also responsive to a feedback signal from a current detector 13. In an alternative embodiment, (Figure 7), there is no discharging circuit 12 and the value of a resistor in series with the charging path of the battery 4 from supply 1 is switched in dependence on the battery discharge rate. <IMAGE>

Title: High voltage dynamic focusing system
Inventor: SKOW LAWRENCE H
IPC: G09G1/16
Filed: 1985-01-25
Abstract: A C.R.T. display system 10 has a dynamic focus circuit 86 to compensate for the inherent defocussing of a beam from an electron gun 20 on to a display screen 16. Circuit 86 receives a variable focusing signal 88 of bandwidth from zero to a predetermined frequency and includes a network 110 combining a reference voltage from the anode supply 28, a first portion of the applied focusing signal amplified 98 and coupled via capacitor 108, and a second portion of the applied signal amplified 100, to produce at focus electrode 24 a composite focusing signal 19 which has a nominal focusing voltage level which focuses the beam at the screen center 82. The balancing circuit 102 attenuates this level at the output of the amplifier 100. The circuit 86 has a substantially uniform transfer function relating the applied signal 88 to the composite focusing signal 19 that is frequency independent over the bandwidth of the applied signal so that the composite focusing signal 19 provides accurate focusing both when the beam is fixed off-center or moving. <IMAGE>
