  • Apparatus and method for actuating arms
    Patent number: 6702010
    Abstract: In an apparatus and method for actuating arms used on a borehole data-logging tool to deploy measuring instruments against a borehole wall, a mandrel is provided. At least one arm carried by the mandrel is mounted to the mandrel to move between an expanded position, in which a part of the arm projects from the mandrel, and a retracted position. A resilient biassing compression spring provides a resilient biassing force on each arm for biassing the arm towards its expanded position. A hydraulic piston and cylinder assembly associated with each arm restrains the arm against movement towards its expanded position. A drive piston and cylinder assembly acts upon the resilient biassing compression springs for adjusting the resilient biassing force acting upon each arm.

  • Cutting of a stream of tobacco into measured weight portions
    Patent number: 3978987
    Abstract: Method and apparatus for dispensing particulate material in portions of predetermined weight by providing a flow of material measurable by a radiation detector, measuring the flow rate per unit time of the material and removing successive determined portions of the material from the flow when the measurement indicates that each such portion is of predetermined desired weight.
