  • Patent number: 6281455
    Abstract: A force-responsive sensor comprises upper and lower cover layers, one superimposed on the other. The underside of the upper layer carries a first conductive layer which is electrically insulated from a second conductive layer carried by the upper surface of the lower cover sheet by a series of electrically insulating spacers placed along the length of the sensor with longitudinally spaced gaps between them, each spacer extending over substantially the full width of the sensor and being obliquely inclined to the longitudinal direction of the sensor.

  • Patent number: 4055084
    Abstract: A liquid flow meter comprises a housing having a cylindrical piston chamber and a control chamber. A measuring piston is movable in the piston chamber and a flow control slider is movable in the control chamber and it has respective oppositely directed control surfaces which are made effective, by the flow of liquid between the inlet to the housing and a communication between the measuring piston chamber and the control chamber to move the control slider in a control direction. At each end position of the slider, there is a magnetic holding device for holding the slider until a predetermined control pressure is brought to bear against it to move it in an opposite direction. At each limit of its movement, the piston engages and charges an energy or power storage device operable to accelerate its movement in the opposite direction. The control movements of the slider for regulating the flow between the inlet and the outlet are varied in accordance with the position of the measuring piston.
