Abstract: CONTROL CIRCUIT FOR GAS HEATED APPLIANCE                  ABSTRACT OF THE DISCLOSURE           A normally closed, single pole, single throw, thermostatic switch is electrically connected in parallel relationship across a timer motor.  The parallel network constituted by the timer motor and switch is connected in series relationship with a gas burner regulation cir-cuit.  The series-parallel network, constituted by the interconnected timer motor, thermostatic switch, and bur-ner circuit, is electrically connected between two main power lines via timer motor controlled contacts.  The impedance of the timer motor is substantially greater than the impedance of the burner circuit.  Thus, when the thermostatic switch opens, the timer motor runs while the series-controlled lower impedance burner control circuit, and its associated gas burner, do not operate. Under predetermined decreasing temperature conditions, the thermostatic switch will reclose to deenergize the timer motor and energize the burner control circuit.  Such a simplified control circuit provides for both time and temperature dependent regulation of the associated gas burner, such as is used in a gas heated automatic clothes dryer of the domestic type.

Abstract: ABSTRACT OF THE DISCLOSURE A sticking material for preventing resticking comprises an adhesive layer, a second layer laminated on one main surface of the adhesive layer r a peeling agent layer laminated on the second layer and a first layer laminated on the peeling agent layer by coating with a resin.  The rela-tive adhesiveness of the various layers is satisfied by the equation:                          a  <  b wherein a represents the force required to separate the first layer from the second layer through the intermediary of the peeling agent layer, and b represents the adhesive power of the adhesive layer to a material being sealed. Since the second and first layers are adhered temporarily via the peeling agent layer in a condition whereby resticking is impossible, the first layer once being separated from the second layer can not be readhered.

Abstract: S P E C I F I C A T I O N            "Devices for Imparting Rotary Motion"                 ABSTRACT OF THE DISCLOSURE           A down-hole signal transmitter includes an annular impeller mounted on a cylindrical casing and arranged to be driven by the mud flow passing along a drill string.  Each of the impeller and the casing incorporates two sets of magnets with their poles arranged axially relative to one another such that axial movement of the impeller in one direction will tend to be resisted by a force of magnetic repulsion acting between the first set of casing magnets and the second set of impeller magnets and axial movement of the impeller in the opposite direction will tend to be resisted by a force of magnetic repulsion acting between the second set of casing magnets and the first set of impeller magnets.  In this way the axial thrust due to the fluid flow is largely taken up.  Furthermore the magnetic coupling between the magnet sets is such as to enable driving torque to be transmitted by the impeller to a rotary drive member on which the casing magnets are mounted.

Abstract: SELECTIVE CHEMICAL DETECTION BY  ENERGY MODULATION OF SENSORS                  ABSTRACT OF THE DISCLOSURE    A portable instrument for use in the field in detecting, identifying, and quantifying a component of a sampled fluid includes a sensor which chemically reacts with the component of interest or a derivative thereof, an electrical heating filament for heating the sample before it is applied to the sensor, and modulating means for continuously varying the temperature of the filament (and hence the reaction rate) between two values sufficient to produce the chemical reaction.  In response to this thermal modulation, the sensor produces a modulated output signal, the modulation of which is a function of the activation energy of the chemical reaction, which activation energy is specific to the particular component of interest and its concentration.  Microprocessor means compares the modulated output signal with standard responses for a plurality of components to identify and quantify the particular component of interest.  In particular, the concentration of the component of interest is proportional to the amplitude of the modulated output signal, while the identifying activation output energy of the chemical interaction indicative of that component is proportional to a normalized parameter equal to the peak-to-peak amplitude divided by the height of the upper peaks above a base line signal level.

Abstract: ABSTRACT OF THE DISCLOSURE:           This invention relates to a control system for heat supply as hot water from nuclear power plants equipped with condensation units.   This leads to the increased efficiency of the nuclear power plant on the basis of heat extraction from the turbine and its utilization for district heating with hot water as agent.  The system requires a turbine nonadjustable bleeding through which a steam flow is extracted.  A flow nozzle for steam flow measurement is provided on the steam transport line, a pressure transducer which sends a signal to a comparing and control unit which receives also a signal from another pressure transducer located on the turbine first stage.   The comparing and control unit actuates the motorized steam and condensate valves, performing the turbine protection in case that the steam flow extracted at the nonadjustable bleeding exceeds the allowed limit.  The delivered heat control is performed indirectly by water flow variation in the seconary circuit of district heating by means of a motorized control valve. This  control valve is controlled by means of a heat calculation unit  which receives  signals  from  a  flow transmitter and two thermoresistances.
