Abstract: A battery charging system for battery-powered vehicles has a battery transfer station, at which a vehicle is positioned for removal and replacement of the spent and charged battery. The spent battery is removed from the vehicle and transferred to a charging system, and a charged battery is transferred from the charging system to the vehicle. In one form, the batteries are conveyed through a continuous charging system, upon removal from the vehicle, and a fully charged battery is deposited in the vehicle. In another form, batteries are transferred from and to the vehicle by a battery transfer system which transfers the batteries to and from storage and charging bays. In all cases, the discharged battery is removed from the vehicle, and a charged battery is installed in the vehicle.

Abstract: A clinical thermometer device includes a body with means for reading out temperature electrically or electronically and a probe body supporting a pair of thermo-couple wires which are thin and of themselves not self-supporting, with the thermo-couple junction exposed at an end of the probe body. The probe is oriented with respect to a plug receptacle to establish correct polarity, or wires on the probe and contacts in the plug establish correct polarity regardless of orientation.

Abstract: A battery operated thermometer by which a person's temperature is measured by a thermistor which varies the current flow through a resistance bridge circuit, and the temperature is shown by adjusting a dial to adjust a meter to a null point. A quick connector is employed to connect the disposable probe in the bridge circuit. The probe consists of a pair of conductor wires in an insulating sheath and having bared ends held by pressure only in conductive contact with a thermistor chip by a plastic tip which shrinks to press the bared ends against the chip.
