Abstract: INVENTORS:  J?RG MUGGLI and MARTIN LABHART            INVENTION:  SMOKE DETECTOR WITH A RADIATION SOURCE OPERATED             IN A PULSE-LIKE OR INTERMITTENT MODE                 ABSTRACT OF THE DISCLOSURE           In  a  line  extinction  detector  using  a pulse-operated radiation source, a radiation receiver is connected to an input amplifier of an evaluation circuit. The output pulses generated by the input amplifier are compared to a reference voltage.  Circuit elements having a time constant above one minute are provided to adjust either one of the voltage of the output pulses or the reference voltage such that their difference practically becomes zero.          The output pulses of the input amplifier are further compared to an alarm threshold derived from the reference voltage and an alarm is triggered when the output signal falls below the alarm threshold value.  The output pulses of the input amplifier are also compared to a disturbance threshold value and a disturbance signal is generated when the output signal drops below the disturbance threshold value.  A further disturbance signal value is also triggered at preset limits for the compensating adjustment between the output signal of the input amplifier and the reference voltage.  A device permits to change the ratio of the alarm threshold value and the reference voltage in order to adapt the sensitivity of the smoke detector to different distances between the radiation source and the radiation receiver.

Abstract: SWEPT ORIFICE DISCHARGER AND METHOD     Abstract of the Disclosure In a pressurized materials processing system, separation of solid particulates from a gaseous process fluid is beneficially accomplished by use of a swept orifice discharger comprised of a cylindrical housing that is closed at one end and open at the other end.  The housing contains an impeller within its interior and has a selected, presized orifice in its cylindrical side wall.  In operation, the solid material and gaseous fluid are received in the swept orifice discharger housing and the solid material is continuously centrifugally urged toward the housing side wall so that it separates from the gaseous process fluid and collects of the housing side wall.  Contemporaneous-ly, the impeller continuously sweeps the collected solid material past the orifice, to avoid plugging of the orifice opening, while the pressurized gaseous fluid, which is continuously maintained at desired elevated pressure, blows the collected material through the presized orifice opening with only a controlled or predetermined minor portion of the available pressurized gaseous fluid.  The remaining, clean or substantially particle-free, pressurized gaseous process fluid may then be recycled in the processing system or other-wise conserved, if desired.

Abstract: ABSTRACT OF THE DISCLOSURE         A heater control circuit functions in conjunc-tion with a suitable heating coil to provide precision, automatic  temperature  regulation.   The  combination  of heating and temperature sensing functions into a single system results  in  a  two-wire heater  regulator  control circuit in which a continuous excitation voltage and a power voltage can be simultaneously present at the heater coil.  Temperature of the heater is established by contin-uous excitation and sensing independent of the occurrence of power for heating.  A short circuit protection circuit is responsive to an electrical short in the heater coil (which significantly changes its resistance with tempera-ture) and disables the power voltage.

Abstract: PROTOCOL FOR DETERMINING PHYSICAL ORDER OF ACTIVE STATIONS ON A TOKEN RING    ABSTRACT      A reconfigurable serial loop or ring communication system is provided with a method and apparatus which enables stations on the loop to ascertain the address of its nearest active upstream neighbor (NAUN).  A Ring Poll Frame is generated and broadcast from an originating station.  The Ring Poll Frame includes a Ring Poll command, a From Address and a reset Address Recognized (AR) control bit.  The first active downstream station recognizes the command with the control bit in the reset state, copies the contents of the ring poll frame and sets the bit.  The set bit inhibits subsequent downstream stations from copying the frame. The first active station then generates a substantially similar formatted ring poll frame and passes it downstream.  The process is continued by downstream active stations until the originating station receives a ring poll frame having a reset control bit. The reset control bit is an indication that all stations on the loop know the address of its NAUN.      A ring management station may use the ring poll process to acquire information relative to the location of active stations on the ring.

Abstract: ABSTRACT          When producing  images of  the earth using rotating planar mirrors mounted in an aircraft,   errors are introduced by roll,  pitch and yaw of the aircraft.    These errors are overcome in one of two ways.  In the first way, the scanning planar mirror is mounted on a shaft,  the axis of which can be moved through small angles  during  the  rotation  of  the  shaft.   This movement of the shaft is achieved by supporting the shaft so that the end which does not carry the mirror is located within a cylindrical hollow region at the end  of  an  outer  shaft.   The  two  shafts  rotate together.  A pair of permanent magnets,  each mounted axially in a respective shaft,  have opposite poles adjacent to each other. The attraction of the magnets is  perturbed  by   a  transverse  magnetic  field established by an electromagnet mounted outside the outer  shaft.   The  current  in  the  winding  of the electromagnet depends upon the value of signals which are proportional to pitch and yaw of the aircraft.          Those signals are derived from a gyroscope system.          The second mechanism for overcoming errors involves mounting the scanning,  planar mirror in a cylinder which is part of an inertial system that, in turn, is mounted on gimbals.  Radiation received by the mirror is reflected by a system of mirrors which is similar to a Cassegrain telescope.  The radiation is finally reflected  by  an  elliptical  mirror to  radiation monitoring  equipment.    In  each   case,    signals indicative of the roll of the aircraft are used to control the time at which samples of the incoming radiation are first monitored.

Abstract: ABSTRACT OF THE DISCLOSURE:     In a low bit-rate coding device for coding a discrete speech signal sequence into an output code sequence for use in exciting a synthesizing filter, an autocorrelation function of an impulse response calculated for the synthesizing filter by using a parameter sequence representative of a spectral envelope of the segment and a cross-correlation function between the segment and the impulse response are used to produce a sequence of excitation pulses by successively deciding locations and amplitudes of the pulses with the location of a currently processed pulse decided by the use of the locations and the amplitudes of previously processed pulses and with renewal of the previously processed pulse amplitudes carried out concurrently with decision of the currently processed pulse amplitude by the use of the previously and currently processed pulse locations.          Alternatively, the currently processed pulse location and the previously and currently processed pulse amplitudes are decided by the use of the previously processed pulse locations. The parameter and the excitation pulse sequences are coded and then combined into the output code sequence.  The correlation functions are preferably calculated with the segment and the impulse response weighted by weights dependent on the parameter sequence.  The segment may be a frame of the speech signal sequence or a subframe of a constant or variable length.
