Abstract: ABSTRACT:         Digital information can be applied to a data transfer station from a first memory by means of a first read-out device. The information read is tempora-rily stored in a second memory. When the second memory reaches a first degree of filling in the upwards direc-tion, the first read-out device is blocked after a given delay. When the second memory in its turn has output information elements, so that a second degree of filling is signalled, the first read out device is un-blocked after a given delay. The second memory is serial-ly organized. In as far as the said degrees of filling are not determined, at least the minimum value of the first degree of filling is equal to (or higher,than) the maxi-mum value of the second degree of filling. Notably the delay incurred upon blocking can be caused by the run-out time of a mechanical device, by information delay times or in that the blocking of the transfer per se implies a number of delaying procedure steps.

Abstract: Abstract of the Disclosure Flame supervisory method and apparatus in which a cross-checking relay system is controlled jointly by time-delay factors and a two-state control signal derived from the flame and having respectively pre-flame and flame-responsive polarity characteristics produced by reflexive bias and regenerative amplification and conversion of the basic flame-detection current to a control signal determining either switch-over to full flame burner operation or lockout of the system under ignition failure conditions. The two control states of the converted flame-detection signal are of a self-locking character, the pre-flame state tending to inhibit false response of the relay system to spurious flame signals, and the converted control signal in general being highly discriminative owing to an abrupt, non-linear change in polarity differentiating it from the pre-flame state.

Abstract: Abstract of the Disclosure The invention relates to an improved method of fluidization and more particularly of drying bulk material.  A fluidizing fluid is introduced at the bottom of a bed to be fluidized at a velocity which is by at least one order of magnitude greater than the velocity of fluidization.  The flow direction of the fluidizing fluid which withdraws from the orifices of a distributor is parallel to the bottom of the bed.  It has been found that such inflow direction and velocity in connection with the pulsation of the latter and the employment of a plurality of level inlets results in vigorous circulating currents or fluxes throughout the bed by which the entire material of the latter is set into uniform bubbling motion.  Thus, a homogeneous loose bed can be obtained in an unusually broad band of velocities.  In addition, no particles will deposit in the inlets of the fluidizing fluid since they would be unable to proceed against a horizontal flow of high speed gaseous media.

Abstract: ABSTRACT OF THE DISCLOSURE A method and apparatus are described for re-ducing or removing the background noise caused by thoron gas (220Rn) in uranium exploration conducted by the detection of radon gas (222Rn) emanating from the ground. This is accomplished by the use of a number of alpha particle detectors, each of which is disposed in a protective enclosure.  A permselective membrane, which permits, but selectively retards, the passage therethrough of gases is disposed in the path to be traversed before such gases can reach the alpha particle detector.  The retarding influence of the membrane should be sufficient to make the concentration of thoron inside the enclosure small relative to the concentration of thoron outside the enclosure.  The influence of the membrane on radon should be negligible, i.e. the radon concentration inside and outside the enclosure should be substantially equal,

Abstract: ABSTRACT OF THE DISCLOSURE        A circuit for providing immunity from noise and nuisance tripping for a ground fault protective device having two or more electrical contacts connected to an electrical distribution system having two or more conductors.  The cir-cuit has means for tripping the electrical contacts of the ground fault protective device connected to the first two conductors.  A power supply is connected to the second of the two conductors and the tripping means.  The tripping means are a selected impedance for limiting current to the power supply when noise voltage in the electrical distribution systems exceeds a predetermined second level so that energy dissipated by the power supply does not exceed the power supply's capacity.          The power supply has means for clipping the noise voltage when it exceeds the predetermined second level.  Ground fault res-ponsive means for producing a fault signal are electrically connected to the two conductors.  Switching means connected to the ground fault responsive means and responsive to the fault signal, and also connected to the power supply and the means for tripping and responsive to a predetermined first level of noise voltage higher than the predetermined second level of noise voltage, are provided as well.  These switching means cause the means for tripping to be energized by the power supply when it receives the fault signal from the ground fault responsive means.

Abstract: A LINEAR PHASE MODULATOR            Abstract of the Disclosure The present invention relates to a linear phase modulator comprising two known Armstrong modulators connected in a balanced configuration to eliminate even-order nonlinearities in the output phase modulated signal.          In addition, a preselected amount of in-phase carrier is added to the quadrature carrier normally added to the output of the suppressed-carrier modulator forming a part of each Armstrong modulator, the carriers being added to each modulator output, however, differing in phase from quadrature by equal and opposite amounts.  By properly preselecting the amount of phase difference from quadrature of the added carriers, third-order nonlinearities can also be substantially eliminated after combining the outputs of the Armstrong modulators in a multiplier circuit.

Abstract: ANGULAR COMPRESSION EXPANSION CYLINDER WITH RADIAL PISTONS.     ABSTRACT OF THE DISCLOSURE        An angular cylinder piston combination for providing compression and expansion chambers in a large number of items, such as compressors, pumps, internal and external combustion engines, hydrostatic generators, air motors, and the like, in which compression and expansion chambers are formed angularly, inside a cylindrical drum which rotates at substantially uniform velocity "Wo". The chambers are formed between N outer radial pistons provided by the drum and N inner radial pistons attached to an inner rotor which accelerates and decelerates from zero velocity to a velocity "2wo" with respect to a stationary housing. A single port per chamber provides intake and exhaust as it comes in coincidence with slots, azimouthally cut on the base of the stationary housing. The inner radial pistons, oscillating within the angle subtended between the outer pistons, do not cross the ports; lubricating oil can then be permitted to run between a pair of sealing elements positioned along those edges of the pistons which slide with respect to other members of the device. The application of this angular cylinder in the desing of an improved Tri-Rotor device is demonstrated.
