Abstract: INVENTORS:     MARTIN LABHART and J?RG MUGGLI            INVENTION:     SMOKE DETECTOR OPERATING ACCORDING TO THE                RADIATION EXTINCTION PRINCIPLE                      ABSTRACT OF THE DISCLOSURE                A smoke detector contains two radiation transmitters and two radiation receivers. Each of the radiation transmitters emits in a different spectral region, for instance, one emits above and the other one below 600 nm. One part of the radiation of both radiation trans-mitters is conducted via a measuring path, which is accessible to smoke, to one of the receivers constituting a measuring radiation receiver, and another part of such radiation is conducted via a comparison path, which is not accessible to smoke, to the other of the receivers consti-tuting a comparison radiation receiver. Connected to both radiation receivers is an evaluation circuit which forms from the measuring radiation intensities prevailing in the two spectral regions and from the comparison radiation intensities prevailing in the same spectral regions a function of the type:                       , By suitably adjusting or selecting the components of the evaluation circuit, the coefficients a and b are selected such that in the absence of smoke in the measuring path, A becomes zero and in the presence of smoke such is proportional to the smoke density.

Abstract: Abstract A non-invasive, real time blood pressure measurement system (10)  includes a cuff (40)  connected to a pump (12), a cuff pressure sensor (48), and a detector (52, 54 or 56) to sense the times when the cuff (40) stops or starts blood flow in a user's body appendage.  The pump (12) cyclically varies the cuff (40) pressure from above systolic to below diastolic levels at a relatively fast rate  compared  to  the  heartbeat  rate  enabling  blood pressure measurements to be made quickly in sequence. Electrical circuitry (50) is provided to make the blood pressure measurement by correlating the cuff pressure with the detected times.  This system is compatible with major types of automatic sphygmomanometric systems.

Abstract: A B S T R A C T         The invention relates to an arrangement for rotor-frequency-dependent short-circuiting of rotor-resistances for driv-ing motors, more particularly in the case of hoist motors.  To this end use is made of a frequency-detecting/and converter unit and a rated-value pre-selector which are connected to a comparison-circuit which produces a short-circuiting command.  The frequency-detecting and converter unit consists of a rotor-frequency-depend-ent gate-circuit which, in the open condition, releases a fixed reference frequency to a counter which, in turn, passes the counted periods of the reference-frequency, through a matrix-circuit such as an EPROM, as a digital rated rotor-frequency value, to a comparison-circuit, rated-value pre-selection being effected digitally by adjustable code-switches at the comparison-circuit.

Abstract: IGNITION DISTRIBUTOR     Abstract of the Disclosure An ignition distributor for an internal combustion engine in which the rotor is locked in a predetermined position by a locking pin fixed to the base of the distributor and having a portion thereof positioned in a slot formed in a plate that rotates with the distributor shaft and rotor.  The rotor is locked in a position in which the electrode or segment thereof faces or is aligned with one of the output terminals of the distributor cap and when the distributor shaft is driven by the engine the locking pin breaks or fractures to permit free rotation of the rotor.  With the arrangement that has been described, the distributor can be assembled to an engine and after assembly provides proper ignition timing without rotative adjustment of the base and cap relative to the rotor.  One end of the locking pin is press-fitted to a bore formed in the base of the distributor so that the pin is permanently fixed to the base.

Abstract: ABSTRACT OF THE DISCLOSURE         Glowing coke descending through a cooling duct in a coking plant is quenched by two gas  flows  respectively traversing an upper compartment and a lower compartment of the duct, the two compartments meeting at a restricted gate for the passage of the coke.  At least the lower gas flow, passing in countercurrent to the descending coke charge, is also circulated through a drying and preheating oven for coal to  be  fed  to a coke-oven battery of  the  plant,  thus containing some water vapor.  When the upper flow is also constituted by coal-drying gas, it is passed downward through the upper compartment in order to reduce the height of a high-temperature zone in which combustion and thus loss of coke could occur.  The coke gate is formed by a funnel-shaped upper  partition and  an upwardly pointing conical lower partition between which a scavenger gas passes in cross-flow.

Abstract: ABSTRACT:          "Multiple redundant clock system comprising a number of mutually syn-chronizing clocks, and clock circuit for use in such a clock system".     A multiple redundant clock system comprises at least n=4 clocks and is self-synchronizing and fault tolerant against the failure of at the most ?(n-1) clocks. Each clock comprises an oscillator cir-cuit which activates a dividing circuit at the end of each period in order to form its own clock signal on the output of the dividing circuit.          Each clock furthermore comprises a deviation-determining device which compares the own clock signal with the clock signals originating from the other clocks in the system. When an excessively large number of the other clock signals deviate during the first half of the (own) period, the own oscillator circuit is decelerated. When an excessively large num-ber of the other clocks signals deviate during the second half of the own period, the own oscillator circuit is accelerated.
