Abstract: ABSTRACT OF THE DISCLOSURE     A gas flow control valve wherein radially disposed vanes are mounted within an annular flange with rotationally mounted shims connecting the radial vanes to the inner peripheral surface of a flange.  The shims are disposed in a rim-to-rim configuration with a groove defined in rims of the shims and a cable laid in the grooves in a serpentine pattern.  By causing one of the shims to rotate by means of a sealed shaft extending through the flange, the remaining shims may be driven by the cable, causing corresponding motion of the vanes. The shims are mounted to the flange by means of pins.  The shims are relatively thin such that they may be hidden beneath overhanging regions on opposite side walls of the flange, exposing only the radially disposed vanes to a gas  flow path.  Fine and coarse control modes are achieved by allowing one of the vanes to be controlled by a shaft through the flange independent of all shims for fine mode control and another shaft driving the shims for control of the remain-ing vanes for coarse mode control.

Abstract: IMPROVED AUTOREGULATING HEATER     ABSTRACT     An autoregulating electrically shielded heater employs a structure of two magnetically permeable members of different Curie temperatures and preferably differing resistivities.          The two members are in electrical contact with one another; having at their interface a very low resistivity layer or member provided by copper or a like material.  A first of the electromagnetic members has the lower Curie temperature and high resistivity while the other of said members has the higher Curie temperature of the two and preferably lower resis-tivity.  A constant current a.c. source is connected to induce currents in the members parallel to their interface.  Below the Curie temperature of the first member, current is substan-tially confined to a narrow region along a surface remote from the interface.  Above the Curie temperature, some of the current spreads into the low resistance layer or member and into the second electromagnetic member where it is confined, due to skin effect to a narrow region adjacent the interface.          The I2R heating is greatly reduced, 6 to 1 in a typical case, so that autoregulation of temperature occurs near the Curie temperature of the first member.  Since the current in the second electromagnetic member is limited in its penetration by skin effect, a low frequency power supply may be employed in a thin device without radiation of the electromagnetic field.

Abstract: ABSTRACT OF THE DISCLOSURE           A fiber optic digital data transmitting system is disclosed which has the capability of transmitting and accurately reproducing digital data signals at the receiver even when the optical signal is attenuated in the fiber optic transmitting medium.  A composite signal is produced at the transmitter which is the time coincident sum of the non-zero amplitude of the digital data signal to be transmitted and a time varying signal which encodes each non-zero amplitude of the digital signal and other information.  The composition signal modulates an optical carrier signal which is coupled to a fiber optic transmission medium which couples the transmitter to the receiver.  At the receiver, the presence of each time varying signal is detected as a non-zero amplitude of the digital signal.  Circuitry is provided in the receiver for producing a pulse in response to the detection of each time varying signal for reproducing the transmitted digital signal and for detecting any information in addition to the non-zero amplitude of the digital signal which has been encoded in the time varying signal.  The present invention is compatible with existing PCM systems which utilize threshold detection.

Abstract: ABSTRACT OF THE DISCLOSURE    An automatic valve for a sewer or the like includes a body having an upstream inlet and a downstream exit for liquid.  A path joins the inlet and exit, and a closure gate is hingedly mounted to the body at a substantially horizontal axis located above the path, so that the gate can swing between a first position in which it blocks the path and a second position in which it unblocks the path.  An arm is fixed with respect to the closure gate to swing with it in such a way that the arm is higher when the gate blocks the path than it is when the gate unblocks the path, the arm counterbalancing the closure gate so that the latter normally seeks the second position.  A cage surrounds the arm and communicates with the path, and a float member in the cage under the arm means is free of connection to the arm means or any other part of the apparatus, whereby a rise in liquid level causes the float member to urge upwardly against the arm and close the closure gate.

Abstract: ABSTRACT           The invention relates to a process for restoring to shape a deformed numerical signal and also to a device for putting the process into effect.          The process consists in working out an intermediate analog signal SI for the signal S, noting the times of intersection of the signals SI and S, and working out a binary signal N which passes from one binary state to the other at each of the times of intersection.   The binary signal SN is identical with the signal S1, which is itself equal to the signal S before the deformation of such signal S.   The working out of the intermediate signal SI depends on its law of evolution and on contraints imposed on its slope and amplitude.          Application to numerical signal receivers.

Abstract: Abstract of the Disclosure Tracing, identifying and distinguishing electrical conductors in a power distribution network energized by a varying or alternating voltage is achieved by use of a transmitter which absorbs or conducts pulses of current in the power distribution network, and by a remotely located receiver which detects the electromagnetic field signals corresponding to the current pulses conducted through the network conductor.  The transmitter includes means for varying the time width duration of each pulse of current conducted in relation to the instantaneous voltage present on the conductor during the pulse, in order to deliver pulses which are of substantially uniform and constant energy content.  Discrimination of adjacent electrical conductors is enhanced because the strength of the electromagnetic field signal remains substantially constant despite the alternating or varying nature of the voltage on the distribution network.

Abstract: ABSTRACT OF THE DISCLOSURE      A probabilistic learning element for performing task independent sequential pattern recognition.  Said element receives sequences of objects and outputs sequences of recognized states composed of objects. A plurality of memory means are utilized to store the received objects in sequence and for storing in context learned information including previously learned states, objects contained in previously learned states, positional information for each object in a learned state and other predetermined types of knowledge relating to the previously learned states and the objects contained therein.  The element correlates the sequences of received objects with the learned information relating to previously learned states for providing conditional probabilities to possible sequences of recognized states.  The most likely state sequence is determined and outputted at a recognized sequence when the element detects that a state has ended.  The memory for storing learned information is a context organized memory including a plurality of tree structures having various types of information stored in the nodes thereof with certain of said tree structures including at each node an attribute list referring to other tree structures whereby searching is facilitated and unnecessary searching eliminated.       The element derives support coefficients relating to how much information was available when calculating the conditional probabilities and said support coefficients and conditional probabilities are combined to provide a rating of confidence.          When the rating of confidence exceeds a predetermined level, the element is caused to store the outputted recognized state sequence as a learned state sequence with said memories storing the various types of knowledge relating to said learned sequence of states.
