    摘要: An ionization smoke detector containing at least one ionization chamber operated at an extra low voltage or potential. The ionization chamber contains a sensor employing a measuring electrode and a counter electrode. Ambient air has practically free access to the ionization chamber and there are provided one or more radioactive sources for generating ions, a supply voltage source and an electrical circuit for triggering an alarm. The smoke detector possesses increased operational reliability since circuit elements are provided which enable signal reporting to a central station by means of a low-voltage of about 200 volts, however the sensor is operated at an extra low voltage.

    摘要: A D.C. to D.C. voltage converter for producing a regulated, adjustable D.C. output voltage from an unregulated D.C. input voltage. An inverter produces alternating rectangular output pulses from the unregulated D.C. input, which are rectified to produce the regulated D.C. output voltage, with the timing and duration of the inverter output pulses being determined by alternating rectangular control pulses produced by a control pulse generator.The control pulse generator includes an operational amplifier having an inverting input connected to a positive D.C. reference voltage, and a non-inverting input connected to the slide connection of a potentiometer connected between the regulated positive D.C. output voltage and ground. A diode is connected between the amplifier output and ground to block current flow to ground, thus assuring that the amplifier output error signal is essentially always positive, and is only generated when the non-inverting input voltage exceeds the referenced voltage. Another operational amplifier is connected as an inverter to the output of the first amplifier to produce another equal, but negative, error signal. These two signals are combined in a threshold circuit with an alternating triangular wave voltage to produce alternating triangular pulses corresponding to the positive and negative portions of the triangular wave exceeding the positive and negative error signals. The triangular pulses are converted by a pulse shaping circuit into the alternating rectangular pulses which control the inverter switching circuits.

    摘要: Plastic pigment spheric particles which form a matrix for diazotype reproduction materials are applied to a base sheet. Whether the diazo sensitizing solution is included in admixture with spheric plastic pigment particles or is applied thereafter as a second coating, a matrix is formed having a sensitized diazo layer dispersed throughout. Such diazo matrices permit control of contrast ratios over a wide range. Also such diazo matrices are transferable. The diazo matrix image can be made water fast by an after treatment by means of a solvent. Such a matrix lends itself to the heat development process by retaining the heat generated development agents within the matrix due to its thermoplastic character. In another aspect of the invention multi-color diazo reproduction on a single base sheet employing consecutive overcoatings of the matrix and diazo sensitizing solution after each development can be achieved.
