摘要： A liquid fuel blender dispensing pump having a computer to drive price and volume indicator drums and an interlock shaft to switch on the computer. A reset motor is coupled to reset the drums to zero and then switch on the main pump motor at the beginning of a dispensing cycle. The reset motor is also coupled to drive the interlock shaft and is switched on by movement of an actuator in response to or allowed by removal of the dispensing nozzle from the pump housing.

摘要： An end cutting unit for a mining machine comprises a cutting unit body, a ranging arm carrying a drivable cutting device, said ranging arm being carried by the cutting unit body at a location towards a first end thereof, and a transmission for transmitting drive to the cutting device. In order that the end cutting unit may be adaptable to advance and retreat mining uses as required, transmission is provided with two drive couplings respectively at said first end and at the opposite second end of the cutting unit body to enable rotary drive to be transmitted to the cutting device from a selected one of said drive couplings, and the ranging arm is capable of being set in a position, about which the arm can be ranged, in which the arm extends generally away from the end of the cutting unit body at which is located whichever drive coupling has been selected to impart rotary drive to the cutting device.
