Abstract: TUNING APPARATUS                  ABSTRACT OF THE DISCLOSURE         Tuning apparatus is disclosed for a radio receiver having an adjustable tuning section which exhibits a tuning condition that is adjustable over a frequency range to be tuned to selected broadcast frequencies.  An IF section is coupled to the tuning section to produce an IF signal as a function of the frequency to which the tuning section is tuned.  An IF detector detects whether the IF signal corresponds to a signal received on a broadcast frequency to which the tuning section is tuned.          If the tuning section is tuned to a broadcast frequency, a tuning indicating signal is produced.  This tuning indicating signal is produced whether the received signal is a relatively high or a relatively low level signal.  The IF detector also produces the tune indicating signal if the tuning section is tuned to a frequency that is within a predetermined amount of a broadcast frequency and the received signal is a relatively high level signal.  An adjusting circuit changes the condition of the tuning section in predetermined frequencies selectively in an upward or downward direction.  A sensor senses that the tune indicating signal has been produced so as to enable the adjusting circuit to change the tuning condition of the tuning section by a predetermined frequency step and then to disable the adjusting circuit if the tune indicating signal still is sensed following this frequency change so as to maintain the last-attained tuning condition.  Alternatively, if the tune indicating signal no longer is sensed after the tuning condition has been changed by the predetermined frequency step, the tuning section is returned to its preceding tuning condition by this predetermined frequency step.  Consequently, if the received signal is a high level signal, the tune indicating signal is produced when the tuning condition of the tuning section differs from a broadcast frequency by this predetermined frequency step; and the tuning condition then is changed by this step so as to arrive at the desired broadcast frequency.  If, however, the received signal is a low level signal, the tune indicating signal is produced only when the tuning condition of the tuning section coincides with a desired broadcast frequency, and then this tuning condi-tion is changed by one step followed by a return of one step to the proper condition.     - ii -

Abstract: Abstract:            To control the rotation of wire being fed from a reel, the tension of the wire is sensed by a pivotable arm which, through a valve system, controls operation of a pneumatic cylinder having a reciprocatable piston rod which coacts with a friction clutch.  The rod in one position causes the clutch to brake the reel, in response to low tension, and in another position allows the reel to rotate freely, in response to a higher tension, and the rod is reciprocatable to impart accelerating pulses to the reel through the clutch in response to a still higher tension.

Abstract: ABSTRACT OF THE DISCLOSURE:        The invention relates to a string made of polyvinylidene-fluoride in the form of a stretched monofilament or a bundle of monofilaments which are twisted, braided or otherwise joined together, characterized in that the elasticity of the poly-vinylidene-fluoride monofilament, at a pretensioning force in the range of between 170 and 320 N corresponds approximately to that of a natural gut string.  The strings of the invention do not show a high attenuation at room temperature and therefore rebound faster; they are, at the same time, more elastic than all heretofore known synthetic resin strings  and they do not age as rapidly.

Abstract: A B S T R A C T     This invention deals with an improved electrostatic shield (10) which is adapted to be mounted on the applicator of a conventional diathermy apparatus between the radiating electrode thereof and the patient receiving treatment.  The shield (10) is comprised of a first and a second plurality of electrically conductive strips (24, 28) which form the body portion of the shield and which encircle the current carrying coil (16) of the radiating electrode.  The strips (28) likewise form the face portion (14) of the shield and define a plane which is generally parallel to the plane formed by the current carrying coil (16).         Each strip of the face portion (14) is preferably coupled with one of the strips of the body portion.  However, the face portion strips (28) of the shield extend generally radially inward from the outer periphery of the surface defined by the face of the shield.  These strips then terminate within the inner portion of the area defined by the shield such that the terminating end of the strips are electrically insulated from each other.  A loop (26) is provided to surround and electrically couple each of the strips of the body portion of the shield.  In this configuration, the strips comprise an electrostatic shield (10) which will impede electrostatic field radiated by the current carrying coil (16) located within the applicator head. The shield, however, allows passage of the radiated electromagnetic field in a relatively unimpeded fashion.

Then, in a second treatment zone, they are passed first through a cylindrical zone from which the medium can in part escape radially, and subsequently through a slight-ly conically flared zone from which the medium can also escape laterally.  The speeds of the fluid medium and the filament are selected to be such that the ratio of the residence time of the filament in the cylindrical zone to the residence time in the conically flared zone is from 1:19 to 4:1, preferably from 1:9 to 1:2.

Abstract: PIRZ, F. C. 5-11 CONTINUOUS SPEECH RECOGNITION SYSTEM Abstract of the Disclosure A  continuous speech analyzer is adapted to recognize an utterance as a series of reference words for which acoustic feature signals are stored.  Responsive to the utterance and reference word acoustic features at least one reference word series is generated as a candidate for the utterance.  Successive word positions for the utterance are identified.  In each word position, partial candidate series are generated by determining reference word corresponding utterance segments and combining reference words having a prescribed similarity to their utterance segments with the partial candidate series of the preceding word position.  The determined utterance segments have beginning points within a predetermined range of the utterance position endpoint for the preceding word position candidate series to account for coarticulation and differences between acoustic features of the utterance and those for reference words spoken in isolation.
