Abstract: 1,216,752. Counting particles. MEDICOR MUVEK. Jan. 4, 1968 [Jan. 6, 1967], No. 596/68. Heading G1N. In apparatus for counting particles, e.g. blood corpuscles, in a liquid suspension by counting pulses due to the charge of resistance between electrodes 13, 14 as particles suspended in the liquid pass through an aperture 3, the liquid is sucked into or pushed out of the liquid volume measuring chamber 9 by altering the pressure of the air in chamber 10. Initially, the liquid might be at level 18, an incandescent filament 11 is connected to a source of electric current to increase the pressure in the chamber 10 thereby driving the liquid level below the lower end of electrode 7, the excess liquid leaving the apparatus through a non-return valve 16. The current is then switched off and as the pressure in chamber 10 drops, liquid is sucked from vessel 2 through the aperture 3. Counting is initiated when the liquid level reaches the lower end of electrode 7 and stopped when the liquid level reaches the end of electrode 8. Alternatively, Fig. 2 (not shown), a plunger replaces the filament and photo-electric cells are used to initiate and stop counting. In a third embodiment, Fig. 3 (not shown), a bellows (25) is used to alter the pressure in chamber 10 and counting is carried out when the liquid level is rising and again when the liquid is falling.

Abstract: 1,027,915. Transistor saw-tooth circuits. FERRANTI Ltd. Jan. 8, 1965 [Jan. 8, 1964], No. 795/64. Heading H3T. A saw-tooth generator comprises a Miller integrator having a balanced input stage and having a direct current feedback path operable during the quiescent period. As shown, complementary transistors T1, T2 form a monostable multivibrator in which both transistors are non- conductive during the quiescent period. Transistor T3 and diode D4 are both arranged to be conductive during the quiescent period so that the output O of the Miller integrator comprising transistors T4 . . . T6, is clamped to its input. When a trigger pulse is received at terminal I, transistors T1, T2 become conductive for a period depending on the time constant of the circuit. T3 is turned off for this period, turning off diode D4 and allowing capacitor C4 to charge via R9 and D2 so as to generate a sweep at terminal O. Transistors T1, T2 may alternatively be arranged as an astable multivibrator. In Fig. 4 (not shown), diode D4 is replaced by a series-connected pair of resistors, the clamping feedback during the sweep being inhibited by a switching transistor connected between the junction of the resistors and a point of reference potential. Temperature compensation.-Diodes D2, D3 (in the same container as D4) provide temperature compensation. Transistors T4, T5 should also be in the same container.

Filed: 1980-01-05
Abstract: PURPOSE: To enhance the reliability and working performance of a humidity detetor by spraying air on the moisture sensitive resistor to clean the resistor surface during working and spraying hot air only when the detected humidity exceeds a predetermined value.  
     CONSTITUTION: When the humidity detector is actuated electric power is supplied to the motor (not shown) of blower 2 from AC power source 11 to rotate fan 2a, and air is sprayed on moisture sensitive resistor 1 from blower 2 to scatter toner flying from a developing section and adhering to the surface of resistor 1 and dust in air. Thus, the surface is cleaned. When the humidity detected with resistor 1 exceeds 90%, the 1st timer circuit 10 outputs control signal Sh to turn on switch circuit SW. As a result, a voltage is applied to heater 3 to generate heat, and air from blower 2 is converted into hot air which prevents dew condensation on the surface of resistor 1. When operation is started after dew condensation, hot air is sprayed to dry resistor 1 in a short time.
