摘要: A gauge for measuring a dimensional change, such as a change in the periphery of a test object, is an elastomeric tube filled with an electrically conductive fluid such as mercury. The gauge can be formed into a loop around the test object. Thereafter, any change in, e.g. the circumference of the test object is monitored by measuring the change in resistance (or voltage) between the ends of the tube.

摘要: A device provides an electrically settable resistance and comprises first and second electrodes. Each electrode comprises a redox active material. The device further comprises means defining an environment for each electrode such that the average redox state of the electrodes, taken together, remains substantially constant. The environment-defining means includes an electrolyte between the electrodes. The device further comprises a pair of terminals electrically connected to the first electrode at spaced-apart locations, the electrically settable resistance being defined between the pair of terminals and being a function of the oxidation state of the first electrode. The device further comprises means, including a terminal electrically connected to the second electrode, for defining a control circuit path, including the first and second electrodes and the electrolyte, to enable a control current flowing through the control circuit path to change the oxidation state of the first electrode so that control current flowing in one direction sets the resistance to a lower value and control current flowing in the opposite direction sets the resistance to a higher value.

摘要: The invention relates to a movement detector, more particularly a sensor comprising a container partially filled with a liquid into which three electrodes extend. An input alternating signal is applied to two of the electrodes and an output signal amplitude modulated in accordance with movement of the liquid in the container, is detected from another two of the electrodes by means of a sensing circuit which includes a demodulator for detecting the amplitude modulation and a circuit arrangement which provides a container movement signal in response to successive peaks in the demodulated signal which are in excess of a given threshold value being spaced apart in time from one another by a time dependent upon the peak magnitudes of the demodulated signal.

摘要: An electric water heater that includes a metallic housing having a water inlet and outlet, and a non-electrically conducting liner that is impervious to the action of water. First and second carbon electrodes, each in the form of a plate wedge-shaped in cross-section and having an obliquely disposed flat surface, are arranged within the liner with their respective obliques flat surfaces in parallel spaced relation to define a water passage therebetween. Manually operable means permit the second electrode to be moved relative to the first electrode to vary the width of a water passage defined between the electrodes. The housing supports first and second electric terminals that are insulated from one another, but are in electrical communication with the first and second electrodes. The degree to which water will be heated is dependent on the velocity at which the water flows through the passage between the first and second electrodes, and this velocity being determined by varying the width of the passage between the electrodes by use of the previously mentioned manually operated means.
